Kinds of Assessment System Terms modified by Assessment System Selected AbstractsMoving Toward a Comprehensive Assessment System: A Framework for Considering Interim AssessmentsEDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 3 2009Marianne Perie Local assessment systems are being marketed as formative, benchmark, predictive, and a host of other terms. Many so-called formative assessments are not at all similar to the types of assessments and strategies studied by,Black and Wiliam (1998),but instead are interim assessments. In this article, we clarify the definition and uses of interim assessments and argue that they can be an important piece of a comprehensive assessment system that includes formative, interim, and summative assessments. Interim assessments are given on a larger scale than formative assessments, have less flexibility, and are aggregated to the school or district level to help inform policy. Interim assessments are driven by their purpose, which fall into the categories of instructional, evaluative, or predictive. Our intent is to provide a specific definition for these "interim assessments" and to develop a framework that district and state leaders can use to evaluate these systems for purchase or development. The discussion lays out some concerns with the current state of these assessments as well as hopes for future directions and suggestions for further research. [source] ANNA: A new prediction method for bioassessment programsFRESHWATER BIOLOGY, Issue 1 2005Simon Linke Summary 1. Cluster analysis of reference sites with similar biota is the initial step in creating River Invertebrate Prediction and Classification System (RIVPACS) and similar river bioassessment models such as Australian River Assessment System (AUSRIVAS). This paper describes and tests an alternative prediction method, Assessment by Nearest Neighbour Analysis (ANNA), based on the same philosophy as RIVPACS and AUSRIVAS but without the grouping step that some people view as artificial. 2. The steps in creating ANNA models are: (i) weighting the predictor variables using a multivariate approach analogous to principal axis correlations, (ii) calculating the weighted Euclidian distance from a test site to the reference sites based on the environmental predictors, (iii) predicting the faunal composition based on the nearest reference sites and (iv) calculating an observed/expected (O/E) analogous to RIVPACS/AUSRIVAS. 3. The paper compares AUSRIVAS and ANNA models on 17 datasets representing a variety of habitats and seasons. First, it examines each model's regressions for Observed versus Expected number of taxa, including the r2, intercept and slope. Second, the two models' assessments of 79 test sites in New Zealand are compared. Third, the models are compared on test and presumed reference sites along a known trace metal gradient. Fourth, ANNA models are evaluated for western Australia, a geographically distinct region of Australia. The comparisons demonstrate that ANNA and AUSRIVAS are generally equivalent in performance, although ANNA turns out to be potentially more robust for the O versus E regressions and is potentially more accurate on the trace metal gradient sites. 4. The ANNA method is recommended for use in bioassessment of rivers, at least for corroborating the results of the well established AUSRIVAS- and RIVPACS-type models, if not to replace them. [source] Identifying reading problems with computer-adaptive assessmentsJOURNAL OF COMPUTER ASSISTED LEARNING, Issue 1 2007C. Merrell Abstract This paper describes the development of an adaptive assessment called Interactive Computerised Assessment System (InCAS) that is aimed at children of a wide age and ability range to identify specific reading problems. Rasch measurement has been used to create the equal interval scales that form each part of the assessment. The rationale for the structure and content of InCAS is discussed and then different formats of feedback supplied to teachers are explained. This feedback is accompanied by research-based strategies for remediation, following the principle of ,assessment for learning', which promotes the provision of feedback on how to improve. [source] Sensory Processing and Adaptive Behavior Deficits of Children Across the Fetal Alcohol Spectrum Disorder ContinuumALCOHOLISM, Issue 6 2010Joshua L. Carr Background:, Prenatal alcohol exposure can have detrimental effects on a child's development of adaptive behaviors necessary for success in the areas of academic achievement, socialization, and self-care. Sensory processing abilities have been found to affect a child's ability to successfully perform adaptive behaviors. The current study explored whether significant differences in sensory processing abilities, adaptive behavior, and neurocognitive functioning are observed between children diagnosed with partial Fetal Alcohol Syndrome (pFAS), Alcohol-Related Neurodevelopmental Disorder (ARND), or children who were prenatally exposed to alcohol (PEA), but did not meet criteria for an FASD diagnosis. The influence of IQ on adaptive behavior as well as further exploration of the relationship between sensory processing and adaptive behavior deficits among these children was also examined. Methods:, A secondary analysis was conducted on some of the Short Sensory Profile (SSP) scores, Adaptive Behavior Assessment System,Second Edition (ABAS-II) scores, and Wechsler Intelligence Scale,Fourth Edition/Wechsler Preschool and Primary Scale of Intelligence,Third Edition (WISC- IV/WPPSI,III) scores of 46 children between 3 and 14 years of age with pFAS, ARND, or who were PEA. Results:, Greater sensory processing deficits were found in children with a diagnosis of pFAS and ARND compared to those in the PEA group. Children with an ARND diagnosis scored significantly worse on measures of adaptive behavior than the PEA group. Children with pFAS scored significantly lower than children with ARND or PEA on perceptual/performance IQ. No correlation was found between IQ scores and adaptive behaviors across the FASD diagnostic categories. A significant positive correlation was found between SSP and ABAS-II scores. Conclusions:, Regardless of the diagnosis received under the FASD umbrella, functional difficulties that could not be observed using traditional measures of intelligence were found, supporting guidelines that a broad range of standardized assessments be included when screening children for FASD.

[source] An analysis of the skin care patient mix attending a primary care-based nurse-led NHS Walk-in CentreBRITISH JOURNAL OF DERMATOLOGY, Issue 5 2005S.J. Ersser Summary Background, NHS Walk-in Centres (WiCs) are a new and expanding point of nurse-led primary care access for patients requiring skin care. Little is known about the dermatology case profile of such patients. Objectives, To investigate the skin care patient mix attending a WiC and the feasibility and usefulness of retrieving data from the NHS Clinical Assessment System (CAS), as used by NHS Direct. Methods, Patients over 2 years of age presenting to a WiC in southern England with a nurse-assessed skin condition were recruited over a 12-week period (n = 233). A data set was extracted from CAS and analysed using Excel. Results, Of the total 31 591 patients attending the WiC in the first 2 years, 21% had a skin-related problem. During the 12-week study period, 88 of 233 eligible patients (38%) consented to participate. The typical patient profile was of female patients, 17,35 years (27%) attending during the week before 9 a.m. (35%) or after 5 p.m. (27%) from the locality (72%). CAS employs generic algorithms to specify clinical problems (e.g. rash) rather than medical diagnoses. Most patients presented with a rash (89%). No physical treatment was required in 77% of patients, although this was advised for 46%; 49% were advised to seek help but not return to the WiC; 16% were recommended to contact their general practitioner. There were practical difficulties accessing data from CAS software for research due to research governance requirements. Conclusions, A significant number of patients with dermatological conditions could be seeking primary care through new NHS WiCs. Detailed dermatological appraisal of the patient mix is difficult due to the system of clinical categorization. There is scope to investigate further the nature of dermatological need and the patient education given. CAS is a cumbersome data extraction tool for research. [source] Symptomatic hypogonadism in male survivors of cancer with chronic exposure to opioidsCANCER, Issue 4 2004Arun Rajagopal M.D. Abstract BACKGROUND Profound hypogonadism has been noted in patients receiving intrathecal opioids. The purpose of the current study was to determine whether chronic consumption of oral opioids by male survivors of cancer also would lead to central hypogonadism and whether this hypogonadism was associated with symptoms of sexual dysfunction, fatigue, anxiety, and depression. METHODS A case,control study was conducted at The University of Texas M. D. Anderson Cancer Center (Houston, TX), in which 20 patients who were chronically consuming opioids were compared with 20 matched controls. Patients completed the Sexual Desire Inventory (SDI), the Hospital Anxiety and Depression Scale (HADS), the Functional Assessment of Chronic Illness Therapy with general and fatigue subscales (FACT-G/FACIT-F), and the Edmonton Symptom Assessment System (ESAS) questionnaires. Serum samples were collected for testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). RESULTS Comparing the opioid group with the control group, 18 of the 20 patients (90%; 95% confidence interval [CI], 65,98%) exhibited hypogonadism, compared with 8 of the 20 control patients (40%; 95% CI, 19,64%). The median testosterone level was 145 ng/dL versus 399.5 ng/dL (5.0 nmol/L vs. 13.9 nmol/L; P < 0.0001), the median FSH level was 2.85 milli,International Units (mIU)/mL versus 5.3 mIU/mL (P = 0.08), the median LH level was 1.8 mIU/mL versus 4.2 mIU/mL (P = 0.0014), the median SDI-dyadic score was 18.5 versus 40 (P = 0.01), the median SDI-solitary score was 0 versus 5 (P = 0.007), the HADS (anxiety) score was 8.5 versus 5.5 (P = 0.053), the HADS (depression) score was 7.5 versus 1.5 (P = 0.0002), the FACT-G score was 64 versus 96.3 (P = 0.0001), and the FACIT-F score was 24 versus 46 (P = 0.0003). CONCLUSIONS Survivors of cancer who chronically consumed opioids experienced symptomatic hypogonadism with significantly higher levels of depression, fatigue, and sexual dysfunction. With the increasing use of opioids among patients with cancer, further research in improving quality-of-life outcomes is warranted. Cancer 2004;100:851,8. © 2004 American Cancer Society. [source] Discriminant validity of the International Caries Detection and Assessment System (ICDAS) and comparability with World Health Organization criteria in a cross-sectional studyCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2010Fausto Medeiros Mendes Mendes FM, Braga MM, Oliveira LB, Antunes JLF, Ardenghi TM, Bönecker M. Discriminant validity of the International Caries Detection and Assessment System (ICDAS) and comparability with World Health Organization criteria in a cross-sectional study. Community Dent Oral Epidemiol 2010; 38: 398,407. © 2010 John Wiley & Sons A/S Abstract,,, Objectives:, The aim of this cross-sectional study in preschool children was to assess the ability of International Caries Detection and Assessment System (ICDAS) in discriminating socioeconomic factors associated with the presence of caries lesions at both noncavitated and cavitated thresholds and to compare with the standard World Health Organization (WHO) criteria. Methods:, The study was carried out in Amparo, Brazil, during the National Day of Children's Vaccination including 252 children aged 36,59 months. The same child was independently examined by two calibrated examiners, one using the ICDAS and the other using WHO criteria. Socioeconomic information was also recorded. Associations between socioeconomic factors and presence of caries assessed as binary (caries prevalence) and count outcome (actual dmfs values) obtained by WHO criteria and by ICDAS at noncavitated and cavitated thresholds were evaluated by Poisson regression analysis with robust variance. Results:, Some covariates were significantly associated with the presence of caries evaluated by the WHO criteria and by ICDAS (using score 3 as cut-off point). When noncavitated scores of ICDAS were used to calculate the presence of caries, the discriminant power decreased. When dmfs values were used as outcome, no differences in the associations were observed between two systems or using noncavitated caries lesions. Conclusion:, Cavitated scores of ICDAS present similar discriminant validity compared with WHO criteria when presence of caries is used as outcome; however, when actual dmfs values are used, no differences are observed in using noncavitated or cavitated caries lesions. [source] The International Caries Detection and Assessment System (ICDAS): an integrated system for measuring dental cariesCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 3 2007A. I. Ismail Abstract,,, This paper describes early findings of evaluations of the International Caries Detection and Assessment System (ICDAS) conducted by the Detroit Center for Research on Oral Health Disparities (DCR-OHD). The lack of consistency among the contemporary criteria systems limits the comparability of outcomes measured in epidemiological and clinical studies. The ICDAS criteria were developed by an international team of caries researchers to integrate several new criteria systems into one standard system for caries detection and assessment. Using ICDAS in the DCR-OHD cohort study, dental examiners first determined whether a clean and dry tooth surface is sound, sealed, restored, crowned, or missing. Afterwards, the examiners classified the carious status of each tooth surface using a seven-point ordinal scale ranging from sound to extensive cavitation. Histological examination of extracted teeth found increased likelihood of carious demineralization in dentin as the ICDAS codes increased in severity. The criteria were also found to have discriminatory validity in analyses of social, behavioral and dietary factors associated with dental caries. The reliability of six examiners to classify tooth surfaces by their ICDAS carious status ranged between good to excellent (kappa coefficients ranged between 0.59 and 0.82). While further work is still needed to define caries activity, validate the criteria and their reliability in assessing dental caries on smooth surfaces, and develop a classification system for assessing preventive and restorative treatment needs, this early evaluation of the ICDAS platform has found that the system is practical; has content validity, correlational validity with histological examination of pits and fissures in extracted teeth; and discriminatory validity. [source] Application and evaluation of classification trees for screening unwanted plantsAUSTRAL ECOLOGY, Issue 5 2006PETER CALEY Abstract Risk assessment systems for introduced species are being developed and applied globally, but methods for rigorously evaluating them are still in their infancy. We explore classification and regression tree models as an alternative to the current Australian Weed Risk Assessment system, and demonstrate how the performance of screening tests for unwanted alien species may be quantitatively compared using receiver operating characteristic (ROC) curve analysis. The optimal classification tree model for predicting weediness included just four out of a possible 44 attributes of introduced plants examined, namely: (i) intentional human dispersal of propagules; (ii) evidence of naturalization beyond native range; (iii) evidence of being a weed elsewhere; and (iv) a high level of domestication. Intentional human dispersal of propagules in combination with evidence of naturalization beyond a plants native range led to the strongest prediction of weediness. A high level of domestication in combination with no evidence of naturalization mitigated the likelihood of an introduced plant becoming a weed resulting from intentional human dispersal of propagules. Unlikely intentional human dispersal of propagules combined with no evidence of being a weed elsewhere led to the lowest predicted probability of weediness. The failure to include intrinsic plant attributes in the model suggests that either these attributes are not useful general predictors of weediness, or data and analysis were inadequate to elucidate the underlying relationship(s). This concurs with the historical pessimism that we will ever be able to accurately predict invasive plants. Given the apparent importance of propagule pressure (the number of individuals of an species released), future attempts at evaluating screening model performance for identifying unwanted plants need to account for propagule pressure when collating and/or analysing datasets. The classification tree had a cross-validated sensitivity of 93.6% and specificity of 36.7%. Based on the area under the ROC curve, the performance of the classification tree in correctly classifying plants as weeds or non-weeds was slightly inferior (Area under ROC curve = 0.83 ± 0.021 (±SE)) to that of the current risk assessment system in use (Area under ROC curve = 0.89 ± 0.018 (±SE)), although requires many fewer questions to be answered. [source] Connecting EIA to environmental management systems: lessons from industrial estate developments in EnglandCORPORATE SOCIAL RESPONSIBILITY AND ENVIRONMENTAL MANAGEMENT, Issue 2 2007Paul Slinn Abstract This paper concerns the relationship between environmental assessment and environmental management systems in the context of recent industrial estate developments. Drawing on environmental statements and interviews with developers, an examination was carried out of the level of good practice in estate design and operation, and the way in which this was influenced by environmental impact assessment and environmental management systems. The study concludes that the environmental impact assessment system worked well within the context of land use planning, but that it failed to facilitate the planning of effective environmental management in practice, with the consequence that the projects examined failed to meet many of the good practice criteria against which they were tested. Finally, several recommendations are made to strengthen continuity between the two. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. [source] In-patient management of diabetes mellitus and patient satisfactionDIABETIC MEDICINE, Issue 5 2002A. Bhattacharyya Abstract Aims To devise a system for assessing in-patient glycaemic control and care satisfaction in diabetic patients admitted to hospital for reasons other than their diabetes. Methods Consecutive January to March 2001 case-notes were reviewed. Admissions with acute metabolic complications, acute myocardial infarction and pregestational or gestational diabetes were excluded. Glycaemic control, frequency of blood monitoring and management of hyperglycaemia were recorded. The diabetes treatment satisfaction questionnaire was used to assess preadmission satisfaction with care. Post-admission a 12-stem questionnaire was used to assess satisfaction with in-patient diabetes management. Results Hypoglycaemia was common. Although none developed a hyperglycaemic emergency, high blood glucose was prevalent and, frequently, persistent hyperglycaemia or recurrent hypoglycaemia was not acted on appropriately. The overall score for in-patient satisfaction with treatment was fair (4.1 ± 1.8 on a six-point scale; 6 = very satisfied and 1 = very dissatisfied). Scores were higher among patients on surgical wards than on medical wards (P = 0.008), but satisfaction did not vary when patients were stratified according to sex, age and mode of treatment. Conclusion Current systems are not achieving satisfactory in-patient glycaemic control and there is poor satisfaction with medical in-patient diabetes care. Following changes intended to produce improvements, this assessment system can be used recurrently to monitor in-patient care and satisfaction.

[source] Validity of High-Stakes Assessment: Are Students Engaged in Complex Thinking?EDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 3 2004Suzanne Lane The validity of high-stakes assessments and accountability systems is discussed in relation to the requirements of No Child Left Behind (NCLB). The extent to which content standards and assessments are cognitively rich, the challenges in setting performance standards, and the impact of high-stakes assessments on instruction and student learning are addressed. The article argues for quality content standards, cognitively rich assessments, and a cohesive, balanced assessment system. [source] District Accountability Without a State Assessment: A Proposed ModelEDUCATIONAL MEASUREMENT: ISSUES AND PRACTICE, Issue 4 2002Chad W. Buckendahl Most states have adopted assessment and accountability systems that involve common measures of student performance. A state assessment system that allows school districts to choose the specific strategies they use to measure student performance on state-adopted content standards presents a unique state accountability challenge. The authors propose an accountability model that addresses this challenge using a combination of student performance, technical quality, and noncognitive indicators of performance. They also describe a study that evaluated the proposed model using data from all school districts in a southern state. [source] CRAS-CBR: Internal control risk assessment system using case-based reasoningEXPERT SYSTEMS, Issue 1 2004Sung-Sik Hwang Abstract: Information technology and the Internet have been major drivers for changes in all aspects of business processes and activities. They have brought major changes to the financial statements audit environment as well, which in turn has required modifications in audit procedures. There exist certain difficulties, however, with current audit procedures especially for the assessment of the level of control risk. This assessment is primarily based on the auditors' professional judgment and experiences, not on objective rules or criteria. To overcome these difficulties, we propose a prototype decision support model named CRAS-CBR using case-based reasoning to support auditors in making their professional judgment on the assessment of the level of control risk of the general accounting system in the manufacturing industry. To validate the performance, we compare our proposed model with benchmark performances in terms of classification accuracy for the level of control risk. Our experimental results show that CRAS-CBR outperforms a statistical model and staff auditor performance in average hit ratio. [source] Standardized health check data from community-dwelling elderly people: the potential for comparing populations and estimating needHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 1 2000Peter Bath PhD Abstract The main aim of this study was to compare EASY-Care data obtained during nurse-administered annual health checks in two populations of older people. A secondary aim was to determine whether a standardized assessment system administered as part of routine practice by a trained nurse during the over-75 health check could generate useful information for comparing population health and functional status of community-dwelling-older people. One hundred and seventy-nine elderly people (aged 75 years and over) from the Woodstock ward, Belfast, having relatively high deprivation; and 238 elderly people from south Hampshire, ranging from affluent wards in New Forest to inner city wards, were assessed using the EASY-Care assessment system as part of their annual health check. There was a high response rate to the standardized assessment in both populations (75% and 79%). Compared to people in south Hampshire, the people in Belfast had higher relative risk of having fair/poor self-rated health, and lower relative risk of having good/sufficient accommodation and of having difficulty chewing. People in Belfast had a higher relative risk of being dependent for six of the seven IADL items and for continence of urine, bathing, grooming, use of the stairs and dressing among the ADL items. The results demonstrate the ability of data generated by assessment system to discriminate between populations of older people when used as part of routine practice. Differences in health and functional status may be associated with deprivation. Data collected during the annual health check about the health and functional status of older people could provide a useful adjunct to census and survey data to measure population needs and to support locality planning. [source] Assessment of the Ecological Status of Streams in Two Carpathian SubregionsINTERNATIONAL REVIEW OF HYDROBIOLOGY, Issue 4-5 2007Il'ja Krno Abstract A multimetric assessment system was developed to determine the ecological status of two types of stream in the Carpathian ecoregion following the requirements of the WFD. The organic pollution gradient was defined using Canonical Correspondence Analysis. Classification based on physical, chemical and biological data divided the tested sites into two stream types with subsequent grouping into several ecological quality classes. From all the metrics tested, 17 for the East Carpathian streams and 15 for the West Carpathian streams, from seven metric categories, were included in the resulting multimetric index. Different kinds of response to degradation (linear, unimodal, exponential) were observed. The Saprobic index (Zelinka and Marvan), Rheoindex (Banning, with abundance classes) and Index of Biocenotic region, showed the best discriminatory ability for both stream types.

KGaA, Weinheim) [source] European best practice in blood transfusion: improvement of quality-related processes in blood establishmentsISBT SCIENCE SERIES: THE INTERNATIONAL JOURNAL OF INTRACELLULAR TRANSPORT, Issue 1 2007Christian Seidl Transfusion medicine is an expanding field comprising the interaction between several medical disciplines. Looking at the ,vein to vein process' covering the donation of blood by the voluntary donor up to the application of blood components to patients, modern blood transfusion services comprise a large variety of sociomedical functions. The production of standard cellular blood components, such as erythrocyte and thrombocyte concentrates, plasmatic blood components as well as special cellular components such as blood stem cells, mesenchymal cells or granulocytes will require an extensive laboratory testing repertoire to monitor product quality and safety. The European blood legislation has defined several key quality elements to achieve good manufacturing practice in the field of blood transfusion. In addition, GMP/GLP and ISO standards are used inter alia by blood establishments. Following the call for proposal in the field of public health by the European Commission, a consortium of blood establishments from 16 European member, acceding and EFTA states has been established in order to survey the individual quality management systems used by the participants and to developed guidelines for quality systems. These guidelines are aimed at assisting blood establishments in preparing for government inspections as required by Directive 2002/98/EC. They could also be used to adapt existing procedures to comply with current EU requirements and/or to prepare for accreditation and certification of these institutions. Major benefits from those quality management systems are (1) the definition of an overall quality policy, (2) improved personnel responsibility, qualification and training, (3) error and risk assessment system, (4) continuous improvement, (5) improved resource management, (6) performance improvement. The definition of cost,benefit relation between certification and accreditation of blood establishments will depend on the individual institution itself and the amount of processes covered. With the release of the new EU Directive 2005/62/EC, there are currently EU requirements available that describe in detail relevant processes to be covered by quality system following good practice used in blood establishments. A future challenge for transfusion medicine would be optimizing the synergetic effects expressed by the EU directive, GMP and ISO standards. [source] Imputation of 10-year osteoporotic fracture rates from hip fractures: A clinical validation studyJOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2010William D Leslie Abstract The World Health Organization (WHO) fracture risk assessment system (FRAX) allows for calibration from country-specific fracture data. The objective of this study was to evaluate the method for imputation of osteoporotic fracture rates from hip fractures alone. A total of 38,784 women aged 47.5 years or older at the time of baseline femoral neck bone mineral density (BMD) measurement were identified in a database containing all clinical dual energy X-ray absorptiometry (DXA) results for the Province of Manitoba, Canada. Health service records were assessed for the presence of nontrauma osteoporotic fracture codes after BMD testing (431 hip, 787 forearm, 336 clinical vertebral, and 431 humerus fractures). Ten-year hip and osteoporotic fracture rates were estimated by the Kaplan-Meier method. The population was stratified by age (50 to 90 years, 5-year width strata) and again by femoral neck T -scores (,4.0 to 0.0, 0.5 SD width strata). Within each stratum, the ratio of hip to osteoporotic fractures was calculated and compared with the predicted ratio from FRAX. Increasing age was associated with greater predicted hip-to-osteoporotic ratios (youngest 0.07 versua oldest 0.41) and observed ratios (youngest 0.10 versus oldest 0.48). Lower T -scores were associated with greater predicted (highest 0.04 versus lowest 0.71) and observed ratios (highest 0.06 versus lowest 0.44). There was a strong positive correlation between predicted and observed ratios (Spearman r,=,0.90,0.97, p,<,.001). For 14 of the 18 strata, the predicted ratio was within the observed 95% confidence interval (CI). Since collection of population-based hip fracture data is considerably easier than collection of non,hip fracture data, this study supports the current emphasis on using hip fractures as the preferred site for FRAX model calibration. © 2010 American Society for Bone and Mineral Research [source] Simplified System for Absolute Fracture Risk Assessment: Clinical Validation in Canadian Women,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 2 2009William D Leslie Abstract Absolute 10-yr fracture risk based on multiple factors is the preferred method for risk assessment. A simplified risk assessment system from sex, age, DXA, and two clinical risk factors (CRFs),prior fracture and systemic corticosteroid (CS) use-has been used in Canada since 2005. This study was undertaken to evaluate this system in the Canadian female population. A total of 16,205 women ,50 yr of age at the time of baseline BMD (1998,2002) were identified in a database containing all clinical DXA test results for the Province of Manitoba, Canada. Basal 10-yr fracture risk from age and minimum T-score (lumbar spine, femur neck, trochanter, total hip) was categorized as low (<10%), moderate (10,20%), or high (>20%). Health service records since 1987 were assessed for prior fracture codes (N = 5224), recent major CS use (N = 616), and fracture codes after BMD testing (mean, 3.1 yr of follow-up) for the hip, vertebrae, forearm, or humerus (designated osteoporotic, N = 757). Fracture risk predicted from age and minimum T-score alone showed a significant gradient in observed fracture rates (low 5.1 [95% CI, 4.1,6.4], moderate 11.5 [95% CI, 10.1,13.0], high 25.4 [95% CI, 23.2,27.9] per 1000 person-years; p -for-trend <0.0001). There was an incremental increase in incident fracture rates from a prior fracture (13.9 [95% CI, 11.3,16.4] per 1000 person-years) or major CS use (11.2 [95% CI, 4.1,18.2] per 1000 person-years). This simplified fracture risk assessment system provides an assessment of fracture risk that is consistent with observed fracture rates. [source] Assessment for crisis interventionJOURNAL OF CLINICAL PSYCHOLOGY, Issue 8 2006Rick A. Myer This article describes the triage assessment system (TAS) for crisis intervention. The TAS assesses affective, behavioral, and cognitive reactions of individuals to crisis events. This assessment model offers clinicians an understanding of the type of reactions clients are experiencing as well as the intensity of these reactions. The TAS provides a quick, accurate, and easy-to- use method that is directly usable in the intervention process. The system can also be used to monitor clients' progress during the intervention process. Two case illustrations are presented to demonstrate the use of the model.

[source] Conditions for Infection of Apple by Phytophthora syringaeJOURNAL OF PHYTOPATHOLOGY, Issue 4 2003D. C. Harris Abstract The processes leading to Phytophthora fruit rot were divided into two main stages for the purposes of investigating the effects of temperature and duration of wet periods on pathogen development: oospore germination and infection of fruit by zoospores. It was found that the first stage was markedly affected by temperature over the range 10,20°C and required a wet period of 4,7 days. At 18 and 20°C, activation was low regardless of the length of the wet period. Once oospore germination (first stage) had occurred, free water was necessary for only a few hours for fruit infection (second stage) to occur, but the incidence of infection rose rapidly over the first 48 h, regardless of temperature over the range 10,20°C. From the data obtained, mathematical models were produced relating the incidence of Phytophthora fruit rot to the two weather variables. These models can be used to develop a weather-based risk assessment system for the disease. [source] Workplace-based assessment for general practitioners: using stakeholder perception to aid blueprinting of an assessment batteryMEDICAL EDUCATION, Issue 1 2008Douglas J Murphy Context, The implementation of an assessment system may be facilitated by stakeholder agreement that appropriate qualities are being tested. This study investigated the extent to which stakeholders perceived 8 assessment formats (multiple-choice questions, objective structured clinical examination, video, significant event analysis, criterion audit, multi-source feedback, case analysis and patient satisfaction questionnaire) as able to assess varying qualities of doctors training in UK general practice. Methods, Educationalists, general practice trainers and registrars completed a blueprinting style of exercise to rate the extent to which each evaluation format was perceived to assess each of 8 competencies derived primarily from the General Medical Council document Good Medical Practice. Results, There were high levels of agreement among stakeholders regarding the perceived qualities tested by the proposed formats (G = 0.82,0.93). Differences were found in participants' perceptions of how well qualities were able to be assessed and in the ability of the respective formats to test each quality. Multi-source feedback (MSF) was expected to assess a wide range of qualities, whereas Probity, Health and Ability to work with colleagues were limited in terms of how well they could be tested by the proposed formats. Discussion, Awareness of the perceptions of stakeholders should facilitate the development and implementation of workplace-based assessment (WPBA) systems. These data shed light on the acceptability of various formats in a way that will inform further investigation of WPBA formats' validity and feasibility, while also providing evidence on which to base educational efforts regarding the value of each format. [source] Discriminative validity of the behavior assessment system for children-parent rating scales in children with recurrent abdominal pain and matched controlsPSYCHOLOGY IN THE SCHOOLS, Issue 2 2003PAUL M. ROBINS Examined discriminative validity of the Parent Rating Scale (PRS) of the Behavior Assessment System for Children (BASC; Reynolds & Kamphaus, 1992, Circle Pines, MN: American Guidance Services). Two groups were compared: a cohort with recurrent abdominal pain (RAP) (n= 49) and children from the BASC-PRS standardization sample (n = 49) matched on the background characteristics of age, race/ethnicity, and gender. A multivariate, two-group discriminant function analysis was used to compare groups across standard scores from the nine clinical scales of the PRS. Results demonstrated that children with RAP could be differentiated (Wilks , = .642, F = 6.45, df (9, 88), p < .001), and demonstrated higher scores on the Somatization, Depression, Anxiety, Attention Problems, and Withdrawal scales. Subsequent jackknifed classification analysis, diagnostic efficiency statistics, and an odds ratio for the classification analysis added to the overall validity of results. The practical utility of the BASC-PRS is further supported in light of expanding roles for school psychologists in the assessment and treatment of children with health problems. © 2003 Wiley Periodicals, Inc.

Holmboe MDArticle first published online: 4 DEC 200 Abstract Despite spending a substantial amount of time in structured educational settings during early medical training, most physicians will spend the majority of their career in clinical practice. In the clinical practice setting, physicians become responsible for determining and implementing their own educational program in order to maintain, at a minimum, competence. Pressure to change the nature of continuing medical education (CME) parallels pressure from patients, payers, and policymakers to hold individual physicians more accountable for the care they provide. How can these two forces be brought together more deliberately and effectively? Comprehensive physician assessment provides such an opportunity with the potential to benefit all parties involved in health care, especially patients and physicians. Many assessment methods and tools exist today that can facilitate the integration of CME and quality. Using a multifaceted physician-level performance assessment system has substantial potential to align the public's need and desire to ensure their physician is competent, at a minimum, with providing the physician with meaningful, actionable information and data to improve performance and engage in transformative learning. CME programs need to incorporate more robust assessment as part of the learning activity to facilitate improvements in health care more directly. [source] The Methamphetamine Home: Psychological Impact on Preschoolers in Rural TennesseeTHE JOURNAL OF RURAL HEALTH, Issue 3 2008Comfort B. Asanbe PhD ABSTRACT:,Context:A growing number of children reside with methamphetamine-abusing parents in homes where the illicit drug is produced. Yet, the effects of a methamphetamine environment on psychological child outcome are still unknown. Purpose: To examine whether preschoolers who lived in methamphetamine-producing homes are at increased risk for developing psychological problems. Methods: The participants were 58 white children between the ages of 4 and 5 years; 31 with a history of living in methamphetamine-producing homes and 27 children who live in non-methamphetamine producing homes in rural Tennessee. The groups were similar in age, gender, and socioeconomic background. The groups were compared for behavioral and emotional adjustment using the behavior assessment system for children-parent rating scale-preschool (BASC-PRS-P) form. Biological or custodian parents completed a rating on their preschoolers that provided information about the children's pattern of behavior and feelings. Findings: Preschoolers from the methamphetamine-producing homes showed more externalizing problems than their peers, but were comparable on internalizing problems. On specific behaviors, the data indicate that preschoolers in the methamphetamine group showed higher aggression symptoms than their peers from non-methamphetamine-producing homes. Conclusions: These findings, if replicated, point to the need for mental health screening when a child is removed from a methamphetamine-producing home. [source] Assessing and Documenting General Competencies in Otolaryngology Resident Training Programs,THE LARYNGOSCOPE, Issue 5 2006Rick M. Roark PhD Abstract Objectives: The objectives of this study were to: 1) implement web-based instruments for assessing and documenting the general competencies of otolaryngology resident education, as outlined by the Accreditation Council of Graduate Medical Education (ACGME); and 2) examine the benefit and validity of this online system for measuring educational outcomes and for identifying insufficiencies in the training program as they occur. Methods: We developed an online assessment system for a surgical postgraduate education program and examined its feasibility, usability, and validity. Evaluations of behaviors, skills, and attitudes of 26 residents were completed online by faculty, peers, and nonphysician professionals during a 3-year period. Analyses included calculation and evaluation of total average performance scores of each resident by different evaluators. Evaluations were also compared with American Board of Otolaryngology-administered in-service examination (ISE) scores for each resident. Convergent validity was examined statistically by comparing ratings among the different evaluator types. Results: Questionnaires and software were found to be simple to use and efficient in collecting essential information. From July 2002 to June 2005, 1,336 evaluation forms were available for analysis. The average score assigned by faculty was 4.31, significantly lower than that by nonphysician professionals (4.66) and residents evaluating peers (4.63) (P < .001), whereas scores were similar between nonphysician professionals and resident peers. Average scores between faculty and nonphysician groups showed correlation in constructs of communication and relationship with patients, but not in those of professionalism and documentation. Correlation was observed in respect for patients but not in medical knowledge between faculty and resident peer groups. Resident ISE scores improved in the third year of the study and demonstrated high correlation with faculty perceptions of medical knowledge (r = 0.65, P = .007). Conclusions: Compliance for completion of forms was 97%. The system facilitated the educational management of our training program along multiple dimensions. The small perceptual differences among a highly selected group of residents have made the unambiguous validation of the system challenging. The instruments and approach warrant further study. Improvements are likely best achieved in broad consultation among other otolaryngology programs. [source] Application and evaluation of classification trees for screening unwanted plantsAUSTRAL ECOLOGY, Issue 5 2006PETER CALEY Abstract Risk assessment systems for introduced species are being developed and applied globally, but methods for rigorously evaluating them are still in their infancy. We explore classification and regression tree models as an alternative to the current Australian Weed Risk Assessment system, and demonstrate how the performance of screening tests for unwanted alien species may be quantitatively compared using receiver operating characteristic (ROC) curve analysis. The optimal classification tree model for predicting weediness included just four out of a possible 44 attributes of introduced plants examined, namely: (i) intentional human dispersal of propagules; (ii) evidence of naturalization beyond native range; (iii) evidence of being a weed elsewhere; and (iv) a high level of domestication. Intentional human dispersal of propagules in combination with evidence of naturalization beyond a plants native range led to the strongest prediction of weediness. A high level of domestication in combination with no evidence of naturalization mitigated the likelihood of an introduced plant becoming a weed resulting from intentional human dispersal of propagules. Unlikely intentional human dispersal of propagules combined with no evidence of being a weed elsewhere led to the lowest predicted probability of weediness. The failure to include intrinsic plant attributes in the model suggests that either these attributes are not useful general predictors of weediness, or data and analysis were inadequate to elucidate the underlying relationship(s). This concurs with the historical pessimism that we will ever be able to accurately predict invasive plants. Given the apparent importance of propagule pressure (the number of individuals of an species released), future attempts at evaluating screening model performance for identifying unwanted plants need to account for propagule pressure when collating and/or analysing datasets. The classification tree had a cross-validated sensitivity of 93.6% and specificity of 36.7%. Based on the area under the ROC curve, the performance of the classification tree in correctly classifying plants as weeds or non-weeds was slightly inferior (Area under ROC curve = 0.83 ± 0.021 (±SE)) to that of the current risk assessment system in use (Area under ROC curve = 0.89 ± 0.018 (±SE)), although requires many fewer questions to be answered. [source] Use and performances of Web-based portfolio assessmentBRITISH JOURNAL OF EDUCATIONAL TECHNOLOGY, Issue 2 2009Chi-Cheng Chang This research explored the influence of a Web-based portfolio assessment system on students' performances. The methodological procedure adopted was to have the experimental group use the system, with the control group using conventional assessment. The study subjects were junior high school students of two computer classes. The experimental results revealed that the use of the system has significant positive influence on students' performances. According to estimated effect size, the most significant indicators were reflection, self-assessment, continuous improvement, goal setting, problem solving, data gathering, work and peer interaction. However, peer-assessment performance was not enhanced significantly. Therefore, one recommendation was to reduce peer-assessment and instead offer specific illustrations to the students as well as the opportunity to drill. [source] | ||||||||||||||||||||||
