Selected AbstractsMeasuring disability in older adults: The International Classification System of Functioning, Disability and Health (ICF) frameworkGERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 1 2008W Jack Rejeski Background: Despite the importance of disability to geriatric medicine, no large scale study has validated the activity and participation domains of the International Classification System of Functioning, Disability, and Health (ICF) in older adults. The current project was designed to conduct such as analysis, and then to examine the psychometric properties of a measure that is based on this conceptual structure. Methods: This was an archival analysis of older adults (n = 1388) who had participated in studies within our Claude D Pepper Older Americans Independence Center. Assessments included demographics and chronic disease status, a 23-item Pepper Assessment Tool for Disability (PAT-D) and 6-min walk performance. Results: Analysis of the PAT-D produced a three-factor structure that was consistent across several datasets: activities of daily living disability, mobility disability and instrumental activities of daily living disability. The first two factors are activities in the ICF framework, whereas the final factor falls into the participation domain. All factors had acceptable internal consistency reliability (>0.70) and test,retest (>0.70) reliability coefficients. Fast walkers self-reported better function on the PAT-D scales than slow walkers: effect sizes ranged from moderate to large (0.41,0.95); individuals with cardiovascular disease had poorer scores on all scales than those free of cardiovascular disease. In an 18-month randomized clinical trial, individuals who received a lifestyle intervention for weight loss had greater improvements in their mobility disability scores than those in a control condition. Conclusion: The ICF is a useful model for conceptualizing disability in aging research, and the PAT-D has acceptable psychometric properties as a measure for use in clinical research. [source] ADHD rating scale IV: psychometric properties from a multinational study as clinician-administered instrumentINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 4 2005S. Zhang Abstract The development of rating scales for attention-deficit/hyperactivity disorder (ADHD) has traditionally focused on parent- or teacher-rated scales. However, clinician-based instruments are valuable tools for assessing ADHD symptom severity The ADHD Rating Scale IV (ADHD RS), clinician administered and scored, has been validated as a useful instrument to assess ADHD symptoms among American children and adolescents. In this study, we assessed the psychometric properties of the scale in a recent clinical trial conducted mainly in Europe with over 600 children and adolescents diagnosed with ADHD. The trial was conducted in 11 European countries plus Australia, Israel, and South Africa. Results based on data in the study indicate that this version of the scale has acceptable psychometric properties including inter-rater reliability, test-retest reliability, internal consistency, factor structure, convergent and divergent validity, discriminant validity, and responsiveness. There were low-to-moderate ceiling and floor effects. The psychometric properties were comparable with other validated scales for assessing ADHD symptom severity. These results were consistent across the 14 countries participating in this trial. Overall, the data from this study support the use of the ADHD RS as a clinician-rated instrument for assessing the severity of ADHD symptoms in children and adolescents in Europe.

[source] Sensitivity, Specificity, and Usefulness of the Dutch Fatigue ScaleINTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 3 2001Lucas J. Tiesinga PhD Purpose. To test the sensitivity, specificity, and usefulness of the Dutch Fatigue Scale (DUFS), which is based on NANDAs defining characteristics of fatigue. Methods. A cross-sectional design was used among domiciliary patients (N = 213) with chronic heart failure (n = 138) and with breastfeeding postpartum women (n = 75). Findings. Calculations of the sensitivity and specificity of the DUFS, comparisons of the average DUFS sumscores between both nonfatigued and fatigued subjects, as well as between patients with chronic heart failure and postpartum women, and correlation coefficients performed with sociodemographic factors (age, gender, education) demonstrate acceptable psychometric properties. Conclusions. The DUFS is a reliable and valid measurement tool for the assessment of fatigue. Practice Implications. Accurate recognition of the existence and extent of fatigue must precede interventions. Easy to use, reliable tools for the bedside nurse are invaluable assets to practice.

Based on the theoretical framework proposed by Watkins and Marsick (1993, 1996, 1997), this paper identifies the differences in seven of the Dimensions of Learning Organization Questionnaire (DLOQ) between traditional state-owned enterprises (SOEs) versus independent listed companies and companies in service versus manufacturing industries in China. Results indicate that the Chinese version of the DLOQ demonstrated acceptable psychometric properties. Service companies exhibit better learning practices than manufacturing companies; however, the independently listed companies failed to show better learning practices than their unlisted counterparts. Implications for practice and future research are discussed. [source] Trust in Nurses Scale: construct validity and internal reliability evaluationJOURNAL OF ADVANCED NURSING, Issue 3 2010Laurel E. Radwin radwin l.e. & cabral h.j. (2010) Trust in Nurses Scale: construct validity and internal reliability evaluation. Journal of Advanced Nursing66(3), 683,689. Abstract Aim., This paper is a report of the continued psychometric evaluation of the Trust in Nurses Scale. Background., Qualitative analyses indicate that trust in nurses is critically important to adult patients. Instruments that distinctively measure this concept are lacking. A middle-range theory of patient-centred nursing care provided the theoretical basis for the Trust in Nurses Scale. Content validity was assessed by an expert panel and patient interviews. Construct validity and reliability were found acceptable using multi-trait/multi-item analysis techniques. These findings were previously reported. Methods., Construct validity and reliability of the Trust in Nurses Scale was assessed in 2007 using data collected during 2004,2005 from 187 hospitalized patients in a haematology-oncology setting. Trust in nurses (the latent factor) was operationalized by five items (manifest variables) using confirmatory factor analyses. Fit statistics included comparative fit index, Tucker-Lewis Index, root mean square error of approximation and the standardized root mean square residual. Internal consistency reliability was assessed using coefficient alpha. Findings., Both a five-item and a four-item version demonstrate acceptable psychometric properties. The five-item version met three fit statistics criteria. Fifty-nine per cent of the variance was explained. A four-item version met all fit statistics criteria. Sixty-six per cent of the variance was explained. Acceptable internal consistency reliability was found for both versions. Conclusion., Previous psychometric testing of the Trust in Nurses Scale provided evidence of the instrument's reliability, content validity and construct validity. The presented analyses further support construct validity. Thus, cumulative findings indicate that the instrument measures with a few items the underlying concept of trust. [source] Translation and restandardization of an instrument: the Early Infant Temperament QuestionnaireJOURNAL OF ADVANCED NURSING, Issue 2 2003Elisabeth O.C. Hall PhD RN Aims of the study. ,To test the psychometric properties of a Danish translation of the Early Infant Temperament Questionnaire (EITQ) and to establish standards for scoring the questionnaire. Rationale. ,The general aim was to create a translation that remained close to the original version, was meaningful for the Danish participants, and had acceptable psychometric properties. Background. ,Patterns of temperament can be discerned early in life and tend to persist over time and across situations. For the past 50 years, temperament has been studied by theorists, clinicians and nurse clinicians to predict behaviour, discover interventions that prevent serious behaviour disturbances, and help parents understand the implications of their child's temperament. Thomas and Chess's conceptualization of temperament in nine categories was the framework for the development of the English-language EITQ. Research methods. ,The translation followed a stepwise process of translation, back translation and consensus. A convenience sample of 204 Danish mothers with 1,4-month old infants completed the translated questionnaire and a demographic questionnaire in 1999. Results. ,Alpha coefficients for the nine subscales ranged from 0·59 to 0·82. All alpha coefficients were comparable to or higher than those reported on the original United States standardization study. There were statistically significant differences between reported United States mean scores and those in the Danish sample. Discussion. ,The psychometric properties of the Danish translation are equal to or better than those reported for the United States study. Differences in mean scores or most subscales point to the need to create Danish profiles for scoring. Conclusions. ,The Danish version of the EITQ has acceptable reliability and is ready for use in Denmark. [source] Developing a Chinese quality of life in dementia instrument for patients with early-to-moderate dementia: an exploratory test of validityJOURNAL OF CLINICAL NURSING, Issue 15-16 2010Yi-Chen Chiu Aims., The purpose of this study was to examine the psychometric properties of the Chinese Dementia Quality of Life instrument, which included testing the different pathways through theoretical quality of life domains (self-esteem, feelings of belonging and sense of aesthetics) to reach outcomes of positive and negative affect. Background., Perceived quality of life in dementia has been conceptualised based on dementia stages. However, the relationships among quality of life domains are unclear in patients with dementia with a Mini-Mental State Examination >10. Design., Cross-sectional study. Methods., Older people (n = 110) were consecutively recruited from memory disorder clinics and community wellness centres (controls). Of these participants, 27 were controls, 39 were diagnosed with questionable dementia and 44 with mild-to-moderate Alzheimer's disease. The instrument was back translated and validated. Results., The instrument has good overall internal consistency (Cronbach's alpha = 0·84,0·94). Item-total correlation coefficients, indicating construct validity, were all significant, except for one item. anova showed that controls, patients with questionable dementia and those with mild-to-moderate Alzheimer's disease differed significantly in scores on Sense of Aesthetics subscale. Instrument total score and scores on three of five subscales (not Feelings of Belonging) differed significantly between control and dementia groups, but not between patients with questionable dementia and those with mild-to-moderate Alzheimer's disease. Factor analyses showed two inconsistencies with the instrument's prior conceptualisation, namely the Self-Esteem and Negative Affect subscales. The Positive Affect path model was supported but not the Negative Affect path model. Conclusions., This patient-reported Dementia Quality of Life instrument has acceptable psychometric properties in Taiwanese patients with dementia with a Mini-Mental State Examination score >10. Relevance to clinical practice., The Chinese Dementia Quality of Life instrument can be used to assess subjective quality of life in Taiwanese patients with dementia with a Mini-Mental State Examination score >10. [source] Psychometric properties of the MacNew heart disease health-related quality of life instrument in patients with heart failureJOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 4 2008Stefan Höfer Abstract Rationale, aims and objectives, Heart failure (HF) is a severe chronic disease and impairs health-related quality of life (HRQL). While validated specific HRQL instruments are required for evaluation of treatment and rehabilitation in patients with HF, a single validated measure to document changes in HRQL for patients with different heart disease diagnoses would be invaluable. The purpose of this analysis was the psychometric analysis of the German MacNew Heart Disease Questionnaire (MacNew) in HF patients, which has previously been shown to be reliable and valid in patients with myocardial infarction, angina pectoris and arrhythmia. Methods, We recruited 89 patients (61.7 ± 11.5 years; 84.3% male) in two Austrian and one Swiss cardiology department with documented HF (effect sizes 28.9 ± 10.1%). The self-administered MacNew, the Short Form-36 (SF-36) and the Hospital Anxiety and Depression Scale were completed. Internal consistency reliability (Cronbach's ,), discriminative and evaluative validity were assessed. Results, Cronbach's , exceeded 0.80. Each MacNew scale differentiated between patients with and without anxiety (3.9 ± 1.0 vs. 5.3 ± 0.8, all P < 0.001), with and without depression (4.2 ± 1.2 vs. 5.2 ± 0.9 all P < 0.03) and by the SF-36 health transition item (deteriorate = 4.39, no change = 4.95, improve = 5.45, all P < 0.02). Evaluative validity was demonstrated with effect sizes >0.70 for a subsample attending a 12-week outpatient rehabilitation programme. Conclusions, The German language version of the MacNew demonstrates consistently acceptable psychometric properties of reliability, validity and responsiveness in patients with documented HF. Together with previous documentation of reliability, validity and responsive, these findings strengthen the argument for the MacNew as a potential ,core' HRQL measure, at least in the German language. [source] University of Rhode Island Change Assessment,Trauma: Preliminary psychometric properties in an alcohol-dependent PTSD sampleJOURNAL OF TRAUMATIC STRESS, Issue 6 2006Yvonne M. Hunt The co-occurrence of posttraumatic stress disorder with substance use disorders (PTSD-SUD) is common and is associated with poorer treatment outcomes. Attrition represents an ongoing, but poorly understood challenge in PTSD-SUD treatment research. The current study examined the initial psychometric properties of the University of Rhode Island Change Assessment,Trauma (URICA-T), a scale designed to assess attitudes and behaviors related to addressing trauma issues, in a sample of 42 individuals meeting diagnostic criteria for PTSD and alcohol dependence. Results suggest that the URICA-T may have acceptable psychometric properties as a continuous measure of motivational readiness in a PTSD-SUD sample. Preliminary data also suggests higher URICA-T scores are associated with retention of alcohol dependent-PTSD participants in a study utilizing trauma-focused exposure. [source] Measuring blood pressure knowledge and self-care behaviors of African AmericansRESEARCH IN NURSING & HEALTH, Issue 6 2008Rosalind M. Peters Abstract The purpose of this study was to develop and conduct preliminary psychometric assessment of instruments measuring knowledge and self-care practices regarding behaviors needed for blood pressure (BP) control among African Americans. Items were empirically derived and scored on a 7-point, bipolar scale. The instruments were evaluated in a sample of 306 community-dwelling African Americans. Results revealed acceptable reliability and validity of the BP Knowledge Scale. Results for the BP Self-Care Scale were mixed. A structural equation model of these scales, recorded BP, and covariates fit well. There was an unexpected positive correlation between self-care and BP suggesting a potential bi-directional relationship. The scales demonstrated acceptable psychometric properties and, with minor revisions, may have clinical utility as measures of BP knowledge and self-care. © 2008 Wiley Periodicals, Inc.

R. Masalu Abstract , Objectives: The objective was to examine the applicability of an abbreviated version of the oral impact of daily performances (OIDP) inventory to Tanzanian adults attending the University of Dar es Salaam. Method: A total of 1123 students (mean age 26.4 years, response rate 58%) completed a survey instrument designed to measure subjective oral health indicators including the eight-item OIDP frequency scores. After a period of 4 weeks, 228 students (mean age 24.6 years, response rate 65%) were examined clinically for the presence or absence of oral disorders. Results: A total of 51% of the participants reported that an oral problem had affected them on at least one daily performance in the 6 months preceding the survey. Cronbach's alpha for the OIDP frequency items was 0.83 and 0.87 on the first and second administration of the questionnaire. A reliability coefficient (Spearman's rho) of 0.87 was obtained for the OIDP frequency scores. For five of the eight OIDP frequency items, the kappa values ranged from 0.60 to 1.0, whereas one scale item had the less satisfactory value of 0.22. Construct validity was demonstrated in that the OIDP frequency scores were statistically significantly associated in the expected direction with clinically observed oral problems and a global self-report indicator of oral health status, respectively. Conclusion: The OIDP frequency scale seems to have acceptable psychometric properties in the context of a descriptive questionnaire survey among Tanzanian university students. [source] | ||||||||||
