Selected AbstractsThe Liverpool Violence Assessment: an investigator-based measure of serious violenceCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 2 2003Rajan Nathan Background Antisocial personality disorder (ASPD) identifies adults with persistent offending behaviour and social dysfunction. However, it lacks discrimination within high-risk and criminal populations and gives little indication of an individual's history of violence. Existing measures of violence have significant limitations. The Liverpool Violence Assessment (LiVA) is an investigator-based standardized interview for measuring patterns of violence. Method A total of 61 male prisoners who had been sentenced for serious violent offences were interviewed using the LiVA and the Structured Clinical Interview for DSM IV antisocial personality disorder and alcohol and drug dependence. Official records of offending were examined. Results The inter-rater reliability for the LiVA was high. There were significant correlations between histories of violence assessed by the LiVA and official records, but the frequency of self-reported violence was much higher than in the official records. Antisocial personality disorder was associated with increased violence. However, analyses revealed marked variability of the levels of violence among those with antisocial personality disorder and contrasting patterns of association of violence with antisocial personality disorder depending on the context. Conclusion The LiVA is a reliable and valid measure of the patterns and characteristics of violence. The findings suggest that the causes of violence should be studied in their own right and not only as a feature of ASPD. Copyright © 2003 Whurr Publishers Ltd. [source] Why do Westerners self-enhance more than East Asians?EUROPEAN JOURNAL OF PERSONALITY, Issue 3 2009Carl F. Falk Abstract Much research finds that Westerners self-enhance more than East Asians, with the exception of studies using the implicit associations test for self-esteem (IATSE). We contrasted Japanese and Canadians on a new measure of self-enhancement under low- and high-attentional load to assess whether cultural differences vary across controlled and automatic processes. Participants also completed measures of relational mobility and the IATSE. Results indicated that Japanese and Asian-Canadians were more self-critical than Euro-Canadians, both under high- and low-attentional load. This cultural difference was partially mediated by relational mobility. The IATSE showed no cultural differences, but this measure did not positively correlate with any of the other measures in the study, suggesting that it is not a valid measure of ,true' self-feelings.

Schmukle The stability of the Implicit Association Test for assessing anxiety (IAT-Anxiety) is lower than its internal consistency, indicating that the IAT-Anxiety measures both stable and occasion-specific variance. This suggests that the IAT-Anxiety may be not only a valid measure of trait anxiety but also one of state anxiety. To test this assumption, two studies were conducted in which state anxiety was experimentally induced by a public speaking task. However, both studies showed that the IAT-Anxiety score did not change when a state of anxiety was induced. Thus, it seems that occasion-specific factors other than variations in state anxiety lead to occasion-specific variance in the IAT-Anxiety score. Implications for the indirect assessment of personality dispositions with the IAT are discussed. Copyright © 2004 John Wiley & Sons, Ltd. [source] The Diabetes Continuity of Care Scale: the development and initial evaluation of a questionnaire that measures continuity of care from the patient perspective,HEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 6 2004Lisa R. Dolovich PharmD MSc Abstract The purpose of the present study was to develop and pilot test a questionnaire to assess continuity of care from the perspective of patients with diabetes. Seven patient and two healthcare-provider focus groups were conducted. These focus groups generated 777 potential items. This number was reduced to 56 items after item reduction, face validity testing and readability analysis, and to 47 items after a preliminary factor analysis. Readability was assessed as requiring 7,8 years of schooling. Sixty adult patients with diabetes completed the draft Diabetes Continuity of Care Scale (DCCS) at a single point in time to assess the validity of the instrument. Patients completed the draft DCCS again 2 weeks later to assess test,retest reliability. A provisional factor analysis and grouping according to clinical sense yielded five domains: access and getting care, care by doctor, care by other healthcare professionals, communication between healthcare professionals, and self-care. The internal consistency (Cronbach's alpha) for the whole scale was 0.89. The test,retest reliability was r = 0.73. The DCCS total score was moderately correlated with some of the measures used to establish construct validity. The DCCS could differentiate between patients who did and did not achieve specific process and clinical indicators of good diabetes care (e.g. Hba1c tested within 6 months). The development of the DCCS was centred on the patient's perspective and revealed that the patient perspective regarding continuity of care extends beyond the concept of seeing one doctor. Initial testing of this instrument demonstrates that it has promise as a reliable and valid measure in this area. [source] Ionic dialysance: Principle and review of its clinical relevance for quantification of hemodialysis efficiencyHEMODIALYSIS INTERNATIONAL, Issue 2 2005Lucile Mercadal Ionic dialysance (D) is an online measured variable now available on several dialysis monitors to evaluate small-solute clearance. Based on conductivity measurements in the inlet and outlet dialysate, the principle of the measurement and the different measurement methods are described. Studies that have evaluated the reliability of ionic dialysance to assess dialysis efficiency are discussed. These studies are divided into two groups: the first comparing ionic dialysance to urea clearance and the second comparing Dt/V to Kt/Vurea, in which the uncertainties of the measurement of Vurea could have misrepresented the relationship between Dt/V and Kt/Vurea. When Kt/Vurea via the Daugirdas second-generation equation taking the rebound into account is considered, slight,even nonsignificant,differences are evidenced between Kt/Vurea and Dt/V. Therefore, ionic dialysance should be considered as a valid measure in future guidelines for dialysis efficiency. [source] Differentiating Type A behaviour and hyperactivity using observed motivation during a reaction time taskINFANT AND CHILD DEVELOPMENT, Issue 2 2003Lilianne Nyberg Abstract In light of the previously found overlap between Type A behaviour as measured by the Matthews Youth Test for Health (MYTH) and hyperactivity scales, the overall aim of this study was to clarify the standing of MYTH-defined Type A behaviour relative to hyperactivity and Attention-Deficit/Hyperactivity Disorder (ADHD), using observed task motivation and performance on a choice reaction-time task, the Complex Reaction Time (CRT) measure. This study included 21 boys exhibiting Type A behaviour, 22 ADHD boys, 20 non-clinically hyperactive boys, and 20 non-hyperactive boys, between the ages of 6 and 13 years. It was proposed that a differentiation of constructs would be possible using observed task motivation if the MYTH were a discriminantly valid measure of Type A behaviour. Results showed that the MYTH-defined Type A group differed from the clinically diagnosed ADHD group, although it was markedly similar to the non-clinical hyperactive group, displaying comparable CRT performance and low level of task motivation. Type A behaviour correlated to CRT performance and task motivation in a way which was conceptually more indicative of hyperactivity than of Type A behaviour, which questions the validity of the MYTH as a measure of the Type A construct. The MYTH Impatience subscale was found to be particularly impure with regard to hyperactivity. Copyright © 2003 John Wiley & Sons, Ltd. [source] Complexity Prediction Instrument to detect ,complex cases' in respiratory wards: instrument developmentJOURNAL OF ADVANCED NURSING, Issue 1 2008Elena Lobo Abstract Title.,Complexity Prediction Instrument to detect ,complex cases' in respiratory wards: instrument development. Aim., This paper is a report of a study to test the hypothesis that the Spanish version of the Complexity Prediction Instrument is a reliable and valid measure of complexity of patients with respiratory disease and to identify the frequency of positive indicators of potential complexity. Background., Respiratory patients are often disabled and severely ill, with co-morbid physical conditions and associated psychosocial problems and need complex nursing care. Method., Trained nurses assessed 299 consecutive adult patients admitted to a respiratory service in Spain from May 2003 until June 2004 with the new, Spanish version of the instrument. Criterion-related validity was tested by studying its ability to predict complexity of care in terms of: severity of illness, scored using the Cumulative Illness Rating Scale; length of hospital stay; ,multiple consultations' during admission; and ,multiple specialists' after discharge. Findings., The hypothesis was supported: patients rating above the standard cut-off point on the Complexity Prediction Instrument scored statistically significantly higher on most of the measures of care complexity studied. Linear regression models showed that the tool was associated with ,length of hospital stay', and predicted both ,multiple consultations' and ,multiple specialists', after controlling for potential confounders. The proportion of ,probable complex cases' was 59·5%. Five positive indicators of potential complexity had a frequency higher than 50%. Conclusion., The Complexity Prediction Instrument is reliable and valid in a new clinical area, respiratory disease. It may be used by nurses for the early prediction of complexity of care. International comparisons may be facilitated with this new Spanish version. [source] Perceived Maternal Parenting Self-Efficacy (PMP S-E) tool: development and validation with mothers of hospitalized preterm neonatesJOURNAL OF ADVANCED NURSING, Issue 5 2007Christopher R. Barnes Abstract Title.,Perceived Maternal Parenting Self-Efficacy (PMP S-E) tool: development and validation with mothers of hospitalized preterm neonates Aim., This paper is a report of a study to develop and test the psychometric properties of the Perceived Maternal Parenting Self-Efficacy tool. Background., Mothers' perceptions of their ability to parent (maternal parenting self-efficacy) is a critical mechanism guiding their interactions with their preterm newborns. A robust measure is needed which can measure mothers' perceptions of their ability to understand and care for their hospitalized preterm neonates as well as being sensitive to the various levels and tasks in parenting. Methods., Using a mixed sampling methodology (convenience or randomized cluster control trial) 165 relatively healthy and hospitalized mother-preterm infant dyads were recruited in 2003,2005 from two intensive care neonatal units in the United Kingdom (UK). Mothers were recruited within the first 28 days after giving birth to a preterm baby. The Perceived Maternal Parenting Self-Efficacy tool, which is made up of 20 items representing four theorized subscales, was tested for reliability and validity. Results., Internal consistency reliability of the Perceived Maternal Parenting Self-Efficacy tool was 0·91, external/test-retest reliability was 0·96, P < 0·01. Divergent validity using the Maternal Self-Report Inventory was rs = 0·4, P < 0·05 and using the Maternal Postnatal Attachment Scale was rs = 0·31, P < 0·01. Conclusion., The Perceived Maternal Parenting Self-Efficacy tool is a psychometrically robust, reliable and valid measure of parenting self-efficacy in mothers of relatively healthy hospitalized preterm neonates. Although application outside the UK will require further cross-cultural validation, the tool has the potential to provide healthcare professionals with a reliable method of identifying mothers of preterm hospitalized babies who are in need of further support. [source] A Preliminary Investigation into the Utility of the Adult Behavior Checklist in the Assessment of Psychopathology in People with Low IQJOURNAL OF APPLIED RESEARCH IN INTELLECTUAL DISABILITIES, Issue 5 2007Nienke H. Tenneij Background, Achenbach & Rescorla (2003) recently developed the Adult Behavior Checklist (ABCL) to assess psychopathology in the general population. The ABCL should be completed by a proxy informant. The use of proxy informants, instead of self-reporting, makes the ABCL potentially suitable for the assessment of psychopathology in adults with intellectual disability. The aim of the present study was to examine reliability and validity of the ABCL in 124 adults with mild intellectual disability or low IQ, and severe challenging behaviour referred for residential treatment. Methods, The ABCL was completed by two independent informants to assess inter-rater reliability. To examine the validity of the ABCL, its relationship with three measures of functioning was assessed. Furthermore, association between scales of the ABCL and DSM-IV axis I disorders was examined. Results, The ABCL was reliable in terms of internal consistency of its scales, and inter-rater reliability. Relationships between clusters of axis I DSM-IV disorders and scales of the ABCL were found as expected. Moreover, ABCL scales predicted different measures of functioning. Conclusions, The ABCL appears to be a reliable and valid measure to assess psychopathology in persons with mild intellectual disabilities or low IQ, admitted for treatment in facilities for adults with mild intellectual disability and severe challenging behaviour. [source] A preliminary study for a new model of sense of communityJOURNAL OF COMMUNITY PSYCHOLOGY, Issue 1 2006Stefano Tartaglia Although Sense of Community (SOC) is usually defined as a multidimensional construct, most SOC scales are unidimensional. To reduce the split between theory and empirical research, the present work identifies a multifactor structure for the Italian Sense of Community Scale (ISCS) that has already been validated as a unitary index of SOC. This study was carried out in two steps: (a) a confirmatory factor analysis was conducted of a three-factor structure, and (b) the author tested the predictive validity of the dimensions to confirm its structure. The study results validate the three-factor solution (i.e., Place Attachment, Needs Fulfillment and Influence, and Social Bonds). Therefore, the ISCS is a valid measure of SOC and a base from which to develop a new model for this construct. © 2006 Wiley Periodicals, Inc. [source] The Danish version of the questionnaire on pain communication: preliminary validation in cancer patientsACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 6 2009R. JACOBSEN Background: The modified version of the patients' Perceived Involvement in Care Scale (M-PICS) is a tool designed to assess cancer patients' perceptions of patient,health care provider pain communication process. The objective of this study was to examine the psychometric properties of the shortened Danish version of the M-PICS (SDM-PICS). Methods: The validated English version of the M-PICS was translated into Danish following the repeated back-translation procedure. Cancer patients were recruited for the study from specialized pain management facilities. Results: Thirty-three patients responded to the SDM-PICS, Danish Barriers Questionnaire II, Hospital Anxiety and Depression Scale, and Brief Pain Inventory Pain Severity Scale. A factor analysis of the SDM-PICS resulted in two factors: Factor one, patient information, consisted of four items assessing the extent to which the patient shared information with his/her health care provider, and Factor two, health care provider information, consisted of four items measuring the degree to which a health care provider was perceived as the one who shares information. Two separate items addressed the perceived level of information exchange between the patient and the health care provider. The SDM-PICS total had an internal consistency of 0.88. The SDM-PICS scores were positively related to pain relief and inversely related to the measures of cognitive pain management barriers, anxiety, and reported pain levels. Conclusion: The SDM-PICS seems to be a reliable and valid measure of perceived patient,health care provider communication in the context of cancer pain. [source] International Experts' Perspectives on the State of the Nurse Staffing and Patient Outcomes LiteratureJOURNAL OF NURSING SCHOLARSHIP, Issue 4 2007Koen Van den Heede Purpose: To assess the key variables used in research on nurse staffing and patient outcomes from the perspective of an international panel. Design: A Delphi survey (November 2005-February 2006) of a purposively-selected expert panel from 10 countries consisting of 24 researchers specializing in nurse staffing and quality of health care and 8 nurse administrators. Methods: Each participant was sent by e-mail an up-to-date review of all evidence related to 39 patient-outcome, 14 nurse-staffing and 31 background variables and asked to rate the importance/usefulness of each variable for research on nurse staffing and patient outcomes. In two subsequent rounds the group median, mode, frequencies, and earlier responses were sent to each respondent. Findings: Twenty-nine participants responded to the first round (90.6%), of whom 28 (87.5%) responded to the second round. The Delphi panel generated 7 patient-outcome, 2 nurse-staffing and 12 background variables in the first round, not well-investigated in previous research, to be added to the list. At the end of the second round the predefined level of consensus (85%) was reached for 32 patient outcomes, 10 nurse staffing measures and 29 background variables. The highest consensus levels regarding measure sensitivity to nurse staffing were found for nurse perceived quality of care, patient satisfaction and pain, and the lowest for renal failure, cardiac failure, and central nervous system complications. Nursing Hours per Patient Day received the highest consensus score as a valid measure of the number of nursing staff. As a skill mix variable the proportion of RNs to total nursing staff achieved the highest consensus level. Both age and comorbidities were rated as important background variables by all the respondents. Conclusions: These results provide a snapshot of the state of the science on nurse-staffing and patient-outcomes research as of 2005. The results portray an area of nursing science in evolution and an understanding of the connections between human resource issues and healthcare quality based on both empirical findings and opinion. [source] The validity and feasibility of saliva melatonin assessment in the elderlyJOURNAL OF PINEAL RESEARCH, Issue 2 2003Nalaka S. Gooneratne Abstract: Recent work in young and middle-aged subjects suggests that melatonin levels in saliva may represent a viable alternative to serum melatonin measurement. We hypothesized that it may be a valid measure of melatonin levels in older adults as well, but features unique to the elderly may limit its utility. To study this, subjects were admitted to an academic medical center where saliva and serum specimens were collected concurrently in dim light conditions during a 14-hr overnight study period and analyzed for melatonin levels with radioimmunoassays (RIAs). Eighty-five subjects over the age of 65 with a broad range of medical conditions participated in the study. Subjects with dementia, depression and anemia were excluded. We found that saliva volume was inadequate for analysis (<200 ,L) in 23.6% of specimens, with the majority of inadequate volume specimens occurring after midnight and inadequate specimens occurring more frequently in females than in males. The correlation coefficient for saliva melatonin and serum melatonin was r = 0.659 (Spearman, P < 0.001), and r = 0.466 for saliva dim light melatonin onset (DLMO) and serum DLMO. Saliva melatonin levels were 30.9% of serum melatonin levels, with a wide range of ratios noted between subjects. Overall melatonin levels influenced both the correlation and ratio of saliva melatonin to serum melatonin; higher correlations and lower ratios were noted when melatonin levels were high. Saliva specimens provide an economical and practical method for melatonin assessment, however, in older adults, issues such as hyposalivation and low melatonin levels limit the feasibility and validity, respectively, of saliva melatonin. [source] Measurement properties of the Villalta scale to define and classify the severity of the post-thrombotic syndromeJOURNAL OF THROMBOSIS AND HAEMOSTASIS, Issue 5 2009S. R. KAHN Summary., The post-thrombotic syndrome (PTS) is a frequent and important complication of deep venous thrombosis (DVT). The diagnosis of PTS is based primarily on the presence of typical symptoms and clinical signs. In the 1990s, a clinical scale known as the Villalta scale was proposed as a measure that could be used to diagnose and classify the severity of PTS. The objective of the present paper was to review the published evidence on the measurement properties of the Villalta scale. Results of the review demonstrate that the Villalta scale is a reliable and valid measure of PTS in patients with previous, objectively confirmed DVT. The scale is acceptable to research subjects and research personnel, and shows responsiveness to clinical change in PTS. Aspects of the Villalta scale that merit further evaluation include test,retest reliability, more detailed assessment of ulcer severity and assessment of responsiveness across the full range of PTS severity. Research aimed at improving the measurement of PTS will also help to improve the overall validity of findings generated by clinical studies of PTS. [source] The Infant Feeding Intentions scale demonstrates construct validity and comparability in quantifying maternal breastfeeding intentions across multiple ethnic groupsMATERNAL & CHILD NUTRITION, Issue 3 2010Laurie A. Nommsen-Rivers Abstract Research tools that are comparable across ethnic groups are needed in order to understand sociodemographic disparities in breastfeeding rates. The Infant Feeding Intentions (IFI) scale provides a quantitative measure of maternal breastfeeding intentions. IFI score ranges from 0 (no intention to breastfeed) to 16 (very strong intentions to fully breastfeed for 6 months). The objective of this study was to examine intra- and inter-ethnic validity of the IFI scale. The IFI scale was administered to 218 white non-Hispanic, 75 African-American, 80 English-speaking Hispanic, 62 Spanish-speaking Hispanic and 64 Asian expectant primiparae. Participants were asked their planned duration of providing breast milk as the sole source of milk (full breastfeeding). The IFI scale was examined for intra-ethnic internal consistency and construct validity and for inter-ethnic comparability. For all five ethnic categories, principal component analysis separated the scale into the same two factors: intention to initiate breastfeeding and intention to continue full breastfeeding. Across ethnic categories, the range in Cronbach's alpha was 0.70,0.85 for the initiation factor and 0.90,0.93 for the continuation factor. Within each ethnic category, IFI score increased as planned duration of full breastfeeding increased (P < 0.0001 for all). Within the planned duration categories of <1, 1,3, 3,6 and ,6 months, the median IFI score by ethnic category ranged from (low,high) 5,8, 9,10, 12,14 and 16,16, respectively. The IFI scale provides a valid measure of breastfeeding intentions in diverse populations of English- and Spanish-speaking primiparae, and may be a useful tool when researching disparities in breastfeeding practices. [source] Concurrent validity of the Berg Balance Scale and the Dynamic Gait Index in people with vestibular dysfunctionPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2003Dr Susan Whitney Abstract Background and Purpose The Berg Balance Scale is a reliable and valid measure that is used to assess characteristics of balance. The Dynamic Gait Index is a relatively new measure that has been used to record dynamic gait tasks in people with vestibular dysfunction. The purpose of the present study was to determine the concurrent validity of the Dynamic Gait Index with the Berg Balance Scale in people with vestibular disorders. Method A retrospective review of the charts of people who met the criteria of having completed both the Berg Balance Scale and the Dynamic Gait Index during their first physiotherapy visit. Seventy patients (19 male, 51 female) were identified through the retrospective review of the charts of people referred for vestibular rehabilitation with varying diagnoses of vestibular and balance dysfunction. All were seen at a tertiary medical centre in an outpatient physiotherapy setting. Their age range was from 14 to 88 years (mean 65 years). Results Correlation between the scores on the Dynamic Gait Index and the Berg Balance Scale was moderate but significant by use of the Spearman rank order correlation (r = 0.71; p<01). No difference was found between scores on the Dynamic Gait Index or Berg Balance Scale based on gender or diagnosis. A significant difference was identified on the Berg Balance Scale between older and younger people with vestibular disorders. Using previously established criteria to determine increased risk of falling, the Berg Balance Scale and the Dynamic Gait Index agreed 63% of the time. Conclusions The moderate correlation between the Dynamic Gait Index and the Berg Balance Scale establishes the concurrent validity of the Dynamic Gait Index in people with vestibular dysfunction. Both these measures provide valuable information to clinicians about patients' functional balance capabilities. However, the lack of perfect correlation indicates that the tests measure different aspects of balance. The Dynamic Gait Index appears to be a more sensitive assessment tool in identifying people with vestibular disorders who are at increased risk for falling, based on currently published criteria.

[source] Comparing Quantitative Measures of Erythema, Pigmentation and Skin Response using ReflectometryPIGMENT CELL & MELANOMA RESEARCH, Issue 5 2002Jennifer K. Wagner We measured a number of pigmentation and skin response phenotypes in a sample of volunteers (n=397) living in State College, PA. The majority of this sample was composed of four groups based on stated ancestry: African-American, European-American, Hispanic and East Asian. Several measures of melanin concentration (L*, melanin index and adjusted melanin index) were estimated by diffuse reflectance spectroscopy and compared. The efficacy of these measures for assessing constitutive pigmentation and melanogenic dose,response was evaluated. Similarly, several measures of erythema (a*, erythema index and adjusted erythema index) were compared and evaluated in their efficacy in measuring erythema and erythemal dose,response. We show a high correspondence among all of the measures for the assessment of constitutive pigmentation and baseline erythema. However, our results demonstrate that evaluating melanogenic dose,response is highly dependent on the summary statistic used: while L* is a valid measure of constitutive pigmentation it is not an effective measure of melanogenic dose,response. Our results also confirm the use of a*, as it is shown to be highly correlated with the adjusted erythema index, a more advanced measure of erythema based on the apparent absorbance. Diffuse reflectance spectroscopy can be used to quantify the constitutive pigmentation, melanogenic dose,response at 7 d and erythemal dose,response at both 24 h and 7 d postexposure. [source] The 14-item Michigan Diabetes Knowledge Test: translation and validation study of the Malaysian versionPRACTICAL DIABETES INTERNATIONAL (INCORPORATING CARDIABETES), Issue 6 2010HK Al-Qazaz MSc Abstract The aims of this study were to translate the Michigan Diabetes Knowledge Test (MDKT) into the Malaysian language, and to examine the psychometric properties of the Malaysian version. A standard translation procedure was used to create the Malaysian version of the MDKT from the original English version. A convenience sample of 307 outpatients with type 2 diabetes was identified between May and October 2009. All data were collected from the Penang General Hospital, Penang, Malaysia. Instruments consisted of the Malaysian version of the MDKT and a socio-demographic questionnaire. Medical records were reviewed for haemoglobin A1c (HbA1c) levels and other clinical data. Reliability was tested for internal consistency using Cronbach's alpha coefficient. Employing the recommended scoring method, the mean±SD of MDKT scores was 7.88±3.01. Good internal consistency was found (Cronbach's alpha = 0.702); the test-retest reliability value was 0.894 (p<0.001). For known group validity, a significant relationship between MDKT categories and HbA1c categories (chi-square = 21.626; p,0.001) was found. The findings of this validation study indicate that the Malaysian version of the MDKT is a reliable and valid measure of diabetes knowledge which can now be used in clinical and research practice.

[source] Screening for distress in cancer patients: is the distress thermometer a valid measure in the UK and does it measure change over time?PSYCHO-ONCOLOGY, Issue 6 2008A prospective validation study Abstract A prospective validation study was conducted in 171 consenting patients from oncology and palliative care outpatient clinics to validate the Distress Thermometer (DT) against the Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire-12 (GHQ-12) and Brief Symptom Inventory-18 (BSI-18) at baseline, four weeks and eight weeks. Receiver Operating Characteristic analysis was used to examine the sensitivity and specificity of the DT scores against the clinically significant cut-off scores of the criterion measures reporting 95% confidence intervals. Standardised response means were used to compare DT scores with criterion measures over time. For a cut-off of 4 vs 5, sensitivity against HADS was 79%, specificity 81%; against GHQ-12, sensitivity was 63%, specificity 83%; and against BSI-18, sensitivity was 88%, specificity 74%. At both four and eight weeks, DT scores tended to change significantly in the same direction as the criterion measures. Ninety-five percent of patients found completing the DT acceptable. The DT is valid and acceptable for use as a rapid screening instrument for patients in the UK with cancer. Our results indicate that it can be used to monitor change in psychological distress over time, but further work is needed to confirm this. Copyright © 2007 John Wiley & Sons, Ltd. [source] Line bisection as a neural marker of approach motivationPSYCHOPHYSIOLOGY, Issue 5 2010Kyle Nash Abstract Approach motivation has been reliably associated with relative left prefrontal brain activity as measured with electroencephalography (EEG). Motivation researchers have increasingly used the line bisection task, a behavioral measure of relative cerebral asymmetry, as a neural index of approach motivation-related processes. Despite its wide adoption, however, the line bisection task has not been confirmed as a valid measure of the precise pattern of activity linked to approach motivation. In two studies, we demonstrate that line bisection bias is specifically related to baseline, approach-related, prefrontal EEG alpha asymmetry (Study 1) and is heightened by the same situational factors that heighten the same approach-related prefrontal EEG alpha asymmetry (Study 2). Results support the line bisection task as an efficient and unobtrusive behavioral neuroscience measure of approach motivation. [source] Evaluating Content Validity and Test,Retest Reliability of the Children's Health Risk Behavior ScalePUBLIC HEALTH NURSING, Issue 4 2006Susan K. Riesch ABSTRACT Objectives: Describe the instrument development process and report the validity and reliability of the Children's Health Risk Behavior Scale (CHRBS), a scale designed to screen for health risk behaviors among youth aged 10,13 Years. Methods: Domain identification and item generation using the Youth Risk Behavior Surveillance Survey from the Centers for Disease Control and Prevention and testing relevance and test,retest reliability among a target audience sample of 77 fifth graders in their classrooms in two separate public school districts. Results: Youth performed their tasks as expert item reviewers effectively. Twenty-one items comprise the CHRBS with a reading level determined to be at the third grade. Conclusions: We have developed a reliable and valid measure to assess late elementary youth's participation in health risk behavior. [source] Assessment of the abbreviated Duke Social Support Index in a cohort of older Australian womenAUSTRALASIAN JOURNAL ON AGEING, Issue 2 2004Jennifer R Powers Objectives: To assess the acceptability, reliability and validity of the 11-item Duke Social Support Index (DSSI) in community-dwelling older Australian women, and to describe its relationship with the women's sociodemographic and health characteristics. Methods: Women aged 70,75 years were randomly selected from the national Medicare database, with over-sampling of rural and remote areas. The mailed survey included items about social support, Medical Outcomes Study Short Form Health Survey (SF-36), health service use, recent life events and sociodemographics. Results: All DSSI items were completed by 94% of the 12 939 participants. Internal reliability was reasonable for 10 of the 11 DSSI items and its factors, social interaction (four items) and satisfaction with social support (six items; Cronbach's alpha of 0.8, 0.6, 0.8). The factor structure was consistent for subgroups of women: urban/non-urban; English speaking/non-English speaking background; married/widowed. Summed scores were highly correlated with factor scores and showed good construct validity. Higher social support was associated with better physical and mental health, being Australian born, more educated and better able to manage on income. Conclusion: Ten of the 11 DSSI items provided an acceptable, brief and valid measure of social support for use in mailed surveys to community-dwelling older women. [source] Evaluation of immunisation coverage for Aboriginal and Torres Strait Islander children using the Australian Childhood Immunisation RegisterAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 1 2004Brynley P. Hull Objective: To estimate immunisation coverage for routinely administered vaccines among children using receipt of a particular Hib vaccine (PRP-OMP) as a proxy for Indigenous status. Methods: Until May 2000, PRP-OMP was provided only for Indigenous children in all jurisdictions except the Northern Territory. In three one-year ACIR-derived birth cohorts, any child recorded on the ACIR as receiving one or more doses of PRP-OMP as the only Hib vaccine was presumed to be Aboriginal and Torres Strait Islander. Using this proxy, estimated numbers of Indigenous children were compared with Australian Bureau of Statistics estimates, and immunisation status for recommended vaccines was estimated at 12 and 24 months by jurisdiction and remoteness compared with children who received other Hib vaccines (presumed non-Indigenous). Results: The numbers of Aboriginal and Torres Strait Islander children estimated using this ,proxy method' are approximately 42% of those estimated by the ABS. Immunisation coverage (among proxy Indigenous children) at 12 months (72,76%) and 24 months (64,73%) was considerably lower than others (90,94% and 81,88%, respectively). These children had significantly lower coverage when living in accessible areas than remote areas. Conclusions and Implications: These data provide the first national measure of immunisation status and are likely to be a valid measure among those identified. Aboriginal and Torres Strait Islander immunisation coverage is 17% lower with the biggest gaps in urban areas, indicating the need for better quality data informing appropriate interventions. [source] The Child Health Questionnaire in Australia: reliability, validity and population meansAUSTRALIAN AND NEW ZEALAND JOURNAL OF PUBLIC HEALTH, Issue 2 2000Elizabeth Waters Objective: To provide reliability, validity and population means for the Australian Authorised Adaptation of the parent-report Child Health Questionnaire (CHQ). Method: We surveyed a representative sample of Australian parents of school-aged children (5,18 years) in Victoria between July and December 1997, using a school-based cluster sample design stratified by educational sector and age. Results: Some 5, 414 parents responded (72%). Good psychometric performance was observed for the CHQ in Australia. Population means demonstrated differences in health on domains of functioning and well-being by age and gender. This population-derived sample demonstrated high ceiling values on Physical Functioning and Social Role scales. Implications: The CHQ appears to be a reliable and valid measure of child and adolescent functional health and well-being for the Australian population. Child health outcomes of children and adolescents with particular conditions or within population subgroups can be compared with these age and gender benchmarks. Appropriate uses for the CHQ may be to discriminate between children who are generally healthy and children with health problems, or in population surveys partnered with measures that extend the range of physical functioning and social functioning.

[source] The emotional burden of miscarriage for women and their partners: trajectories of anxiety and depression over 13 monthsBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 9 2007GP Cumming Objective, To identify the trajectories of anxiety and depression in women and in their partners over 13 months after miscarriage. Design, A prospective study with follow up at 6 and 13 months after miscarriage. Setting, Three Scottish Early Pregnancy Assessment Units. Sample, Of the 1443 eligible individuals approached, 686 (48.3%) consented to participate (432 women; 254 men). Complete data were obtained from 273 women and 133 men at baseline, 6, and 13 months. Methods, On completion of the management of the index miscarriage, eligible and consenting women and men underwent an initial assessment comprising a semi-structured interview and a standardised self-report questionnaire. The latter was readministered at the follow-up assessments. Main outcome measures, The hospital anxiety and depression scale (HADS), a reliable and valid measure of general psychopathology for use in nonpsychiatric samples. Results, Compared with depression, anxiety was overall the greater clinical burden. Over the 13-month period, women reported higher levels of anxiety and depression than men. Over time, a significantly greater level of adjustment was reported by women particularly with regards to the resolution of anxiety symptoms. The effect of time on HADS scores in either gender was similar between subgroups of socio-demographic and clinical factors. Conclusions, These findings verify that early pregnancy loss represents a significant emotional burden for women, and to some extent for men, especially with regards to anxiety. For many, the detrimental effects of miscarriage are enduring and display a complex course of resolution. These findings are discussed in terms of their clinical implications for early identification and management. [source] Separation Anxiety in Parents of Adolescents: Theoretical Significance and Scale DevelopmentCHILD DEVELOPMENT, Issue 1 2001Ellen Hock Parents of adolescents commonly face separation-related issues associated with children's increasing independence and imminent leave-taking. The aims of this investigation were (1) to develop a reliable and valid measure of parental emotions associated with separation and (2) to validate the measure by relating it to other attributes (attachment relationship quality, parent , child communication, and parent , adolescent differentiation) assessed in mothers, fathers, and their adolescents. The newly constructed, 35-item Parents of Adolescents Separation Anxiety Scale (PASAS) was administered to 686 parents of teenagers in grades 6, 8, 10, and 12 or college-bound freshmen and seniors. Factor analyses supported formation of two subscales: Anxiety about Adolescent Distancing (AAD) and Comfort with Secure Base Role (CSBR); both subscales showed distinctive patterns of change with child age. Parents' reports indicated that healthy adult attachment styles were associated with lower AAD and higher CSBR scores; children of parents who had higher AAD scores reported lower quality of attachment to both mothers and fathers. [source] The Leader Observation Tool: a process skills treatment fidelity measure for the Incredible Years parenting programmeCHILD: CARE, HEALTH AND DEVELOPMENT, Issue 3 2008C. Eames Abstract Background Despite recognition of the need to deliver evidence-based programmes in the field of mental health, there is little emphasis on implementing such programmes with fidelity. Attempts by programme developers to ensure adherence to their programmes include the development of training, manuals and content scales, but these alone may be insufficient to ensure fidelity in replication. Observational measures lend themselves as a potentially useful assessment of intervention outcomes, providing accurate and objective accounts of the intervention process. Aim To develop a reliable and valid observational treatment fidelity tool of process skills required to deliver the Incredible Years (IY) BASIC parenting programme effectively. Methods An objective observational fidelity measure was developed to assess adherence to the IY BASIC parenting programme protocol. Observations were conducted on 12 IY BASIC parenting programme groups, attended by parents of pre-school children displaying signs of early onset conduct disorder. Results The Leader Observation Tool (LOT) achieved high internal reliability and good code,recode and inter-rater reliability. Evidence of concurrent validity was also obtained. Conclusions Having demonstrated that the LOT is a reliable and valid measure of implementation fidelity, further research is necessary to examine the relationship between LOT scores and intervention outcome. [source] The post-traumatic embitterment disorder Self-Rating Scale (PTED Scale)CLINICAL PSYCHOLOGY AND PSYCHOTHERAPY (AN INTERNATIONAL JOURNAL OF THEORY & PRACTICE), Issue 2 2009Michael Linden The present study introduces the Post-Traumatic Embitterment Disorder Self-Rating Scale (PTED Scale), which asks for prolonged and disabling embitterment reactions in the aftermath of negative life events. The PTED Scale was administered to four independent samples of patients and normals. Internal consistency and test,retest reliability were high. Factor analysis indicated a two-factor solution, accounting for 55.25% of the total variance. The PTED Scale discriminated significantly between patients who had been classified according to clinical judgement as suffering from pathological embitterment. Correlations with related instruments demonstrated good convergent validity. Data obtained from a non-clinical sample indicated a prevalence of clinically relevant embitterment in the general population of about 2.5%. The PTED Scale is a reliable and valid measure for embitterment as an emotional reaction to a negative life event. Furthermore, results demonstrate that reactive embitterment in connection to a negative life event is a prevalent phenomenon among clinical and non-clinical populations.,Copyright © 2009 John Wiley & Sons, Ltd. [source] Developing an attitude towards bullying scale for prisoners: structural analyses across adult men, young adults and women prisonersCRIMINAL BEHAVIOUR AND MENTAL HEALTH, Issue 1 2009Jane L. Ireland Background,Few studies have attempted to explore attitudes towards bullying among prisoners, despite acknowledgement that attitudes may play an important role. Aim,To evaluate the structure of a new attitudinal scale, the Prison Bullying Scale (PBS), with adult men and women in prison and with young male prisoners. Hypotheses,That attitudes would be represented as a multidimensional construct and that the PBS structure would be replicated across confirmatory samples. Method,The PBS was developed and confirmed across four independent studies using item parceling and confirmatory factor analysis: Study I comprised 412 adult male prisoners; Study II, 306 adult male prisoners; Study III, 171 male young offenders; and Study IV, 148 adult women prisoners. Results,Attitudes were represented as a multidimensional construct comprising seven core factors. The exploratory analysis was confirmed in adult male samples, with some confirmation among young offenders and adult women. The fit for young offenders was adequate and improved by factor covariance. The fit for women was the poorest overall. Conclusion,The study notes the importance of developing ecologically valid measures and statistically testing these measures prior to their clinical or research use. Implications,The development of the PBS holds value both as an assessment and as a research measure and remains the only ecologically validated measure in existence to assess prisoner attitudes towards bullying.
