Acceptable Internal Consistency (acceptable + internal_consistency)
Selected AbstractsA preliminary investigation of the reliability and validity of the Brief Assessment Schedule Depression Cards and the Beck Depression Inventory-Fast Screen to screen for depression in older stroke survivorsINTERNATIONAL JOURNAL OF GERIATRIC PSYCHIATRY, Issue 5 2008A. K. Healey Abstract Objective To conduct an initial assessment of the reliability and validity of the Brief Assessment Schedule Depression Cards (BASDEC) and the Beck Depression Inventory-Fast Screen (BDI-FS) to screen for depression in older stroke survivors. Methods Participants from four inpatient rehabilitation units completed the BASDEC and the BDI-FS together with the Hospital Anxiety and Depression Scale (HADS) for comparison. The Structured Clinical Interview for DSM-IV Axis 1 Disorders (SCID) was then completed with all participants to ascertain a criterion depression diagnosis. The BASDEC and BDI-FS were subsequently completed for a second time. Results Forty-nine stroke survivors (M,=,78.80, SD,=,6.79 years) were included. The BASDEC and BDI-FS demonstrated acceptable internal consistency and test,retest reliability. The BASDEC (cut-off ,7) resulted in a sensitivity of 1.0 and specificity of 0.95 for detecting major depression whereas the BDI-FS (cut-off ,4) had a sensitivity of 0.71 and specificity of 0.74. When participants with minor depression were included in analyses, sensitivity lowered to 0.69 (specificity,=,0.97) for the BASDEC and 0.62 (specificity,=,0.78) for the BDI-FS. Conclusions The BASDEC and BDI-FS were found to have acceptable reliability. The BASDEC demonstrated some advantage in criterion validity over the BDI-FS at the examined cut-offs.

[source] Psychometric characteristics of Cloninger's criteria for personality disorder in a population of French prisonersINTERNATIONAL JOURNAL OF METHODS IN PSYCHIATRIC RESEARCH, Issue 1 2008Antoine Pelissolo Abstract Cloninger has proposed a new procedure to assess personality disorders on the basis of his model of temperament and character. We explored the psychometric characteristics of this instrument in 560 male prisoners, using factor analyses. Results showed that the 20 items relating to the general personality criteria have acceptable internal consistency and that the three-factor structure of the temperament items used to subtype personality disorder are correctly identified by a maximum likelihood factor analysis model with varimax rotation. Overall, 32% of prisoners had a personality disorder according to this model, and it was possible to subtype 68% of these. This new diagnostic procedure for personality disorder seemed to have satisfactory basic psychometric characteristics but further study is required to explore the concurrent validity and the reliability of this instrument.

[source] A psychometric evaluation of the Chinese version of the Cardiovascular Limitations and Symptoms Profile in patients with coronary heart diseaseJOURNAL OF CLINICAL NURSING, Issue 17 2008Violeta Lopez Aims and objectives., The aim of this study was to translate from English and evaluate the validity, reliability and cultural relevance of the Cardiovascular Limitations and Symptoms Profile (CLASP) as a health-related quality-of-life (HRQL) measure in Chinese patients with coronary heart disease. Background., Improvement in HRQL is increasingly used as a primary outcome in determining the treatment benefit using a generic instrument. However, disease-specific instruments are being cited as more responsive and sensitive in detecting even the smallest changes in health status. Therefore, valid and reliable disease-specific measures for patients with coronary heart disease are now being developed and evaluated. Design., Questionnaire design. Methods., The translation equivalence and content validity of the Chinese version of CLASP were evaluated by an expert panel. Measurement performance was tested on a convenience sample of 369 Chinese coronary heart disease patients. Results., The instrument demonstrated good content validity (content validity index 0·94), acceptable internal consistency (>0·70), except for two subscales of angina and tiredness and significant positive correlations among the subscales of CLASP, Hospital Anxiety Depression Scale and the Short Form 36 Health Survey. Principal components analysis revealed nine factors that together explained 69% of the variance. Conclusions., The results of this study support that CLASP is a valid and reliable disease-specific health status measure for Chinese patients with coronary heart disease. However, further item modifications and testings are needed when considering the cross-cultural context. Relevance to clinical practice., The use of disease-specific HRQL measures could effectively evaluate nursing interventions in clinical practice. Further validations of CLASP among different diagnostic groups, such as patients with heart failure and those who have survived an acute myocardial infarction, would provide further empirical support for its use with all patients with heart disorders. [source] The Norwegian version of the American pain society patient outcome questionnaire: reliability and validity of three subscalesJOURNAL OF CLINICAL NURSING, Issue 15 2008Alfhild Dihle MSc Aims and objectives., To examine some psychometric properties of the Norwegian version of the American Pain Society's Patient Outcome Questionnaire (APS-POQ-N). Background., This study is part of an investigation of Norwegian orthopaedic surgical patients, where the overall aim is to evaluate the quality of postoperative pain management. Therefore, an adequate questionnaire on the quality of postoperative pain management was needed. Methods., The sample included 114 orthopaedic postoperative patients. The instrument consists of three main subscales, namely the modified Brief Pain Inventory (modified BPI subscale), the subscale on satisfaction with pain management (Satisfaction subscale) and the subscale on beliefs about pain management (Beliefs subscale), together with six single items about pain management. The reliability of these three main subscales was estimated using Cronbach's alpha coefficients and the construct validity was evaluated using principal-axis factor analysis with oblimin rotation. Results., Face and content validity of the APS-POQ-N were satisfactory, while the modified BPI and the Beliefs subscales showed acceptable internal consistency but the Satisfaction subscale did not. Factor analyses yielded a three-factor solution for the modified BPI, a one-factor solution for the Satisfaction subscale and a two-factor solution for the Beliefs subscale. Conclusions., The APS-POQ-N appears, in general, to be an acceptable method of evaluating postoperative pain management in orthopaedic postoperative patients. However, the alpha value of the Satisfaction subscale was low, and thus the subscale is not recommended for this purpose. Relevance to clinical practice., Reliable and valid instruments are important when performing clinical research. This instrument is applicable as an indicator of quality of postoperative pain management in clinical practice and research. [source] Brief scale measuring patient preparedness for hospital discharge to home: Psychometric properties,JOURNAL OF HOSPITAL MEDICINE, Issue 6 2008James F. Graumlich MD Abstract BACKGROUND: Adverse events occur when patients transition from the hospital to outpatient care. For quality improvement and research purposes, clinicians need appropriate, reliable, and valid survey instruments to measure and improve the discharge processes. OBJECTIVE: The object was to describe psychometric properties of the Brief PREPARED (B-PREPARED) instrument to measure preparedness for hospital discharge from the patient's perspective. METHODS: The study was a prospective cohort of 460 patient or proxy telephone interviews following hospital discharge home. We administered the Satisfaction with Information about Medicines Scale and the PREPARED instrument 1 week after discharge. PREPARED measured patients' perceptions of quality and outcome of the discharge-planning processes. Four weeks after discharge, interviewers elicited emergency department visits. The main outcome was the B-PREPARED scale value: the sum of scores from 11 items. Internal consistency, construct, and predictive validity were assessed. RESULTS: The mean B-PREPARED scale value was 17.3 ± 4.2 (SD) with a range of 3 to 22. High scores reflected high preparedness. Principal component analysis identified 3 domains: self-care information, equipment/services, and confidence. The B-PREPARED had acceptable internal consistency (Cronbach's alpha 0.76) and construct validity. The B-PREPARED correlated with medication information satisfaction (P < 0.001). Higher median B-PREPARED scores appropriately discriminated patients with no worry about managing at home from worriers (P < 0.001) and predicted patients without emergency department visits after discharge from those who had visits (P = 0.011). CONCLUSIONS: The B-PREPARED scale measured patients' perceptions of their preparedness for hospital discharge home with acceptable internal consistency and construct and predictive validity. Brevity may potentiate use by patients and proxies. Clinicians and researchers may use B-PREPARED to evaluate discharge interventions.

[source] Translation and validation of the standard Chinese version of PDQ-39: A quality-of-life measure for patients with Parkinson's diseaseMOVEMENT DISORDERS, Issue 5 2002Kin-Lun Tsang MBBS Abstract PDQ-39 has been widely used in the research and clinical management of Parkinson's disease. It has been translated into and validated in various non-English languages. We report here on the validity and reliability results for the translated standard Chinese PDQ-39 questionnaire. Fifty-four patients were recruited from a movement disorder clinic and two regional patient groups, and data were collected by direct interview. Nineteen patients had the tests repeated 4 weeks later to assess the test,retest and interrater reliability. The standard Chinese version of PDQ-39 demonstrated acceptable internal consistency (Cronbach's , = 0.54,0.90) and was comparable to versions in other languages. Further analysis showed good construct validity and test,retest reliability. Implications and limitations of the study are discussed. © 2002 Movement Disorder Society [source] Reliability and concurrent validity of the Expanded Timed Up-and-Go test in older people with impaired mobilityPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 2 2008Pernille Botolfsen Abstract Background and Purpose.,,Expanded Timed Up-and-Go' (ETUG) was developed to assess each of the subtasks of the ,Timed Up-and-Go' (TUG). The aim of the study was to test the intrarater, interrater, test,retest reliability and internal consistency of the ETUG, and the concurrent validity with the TUG.,Methods.,The present study is a reliability and a validity study. Twenty-eight subjects (80 ± 4.1 years) with balance and gait problems were included. Three raters timed the ETUG subtasks from a video, using a computer-based scoring programme, and the total ETUG time was calculated. TUG was registered by a regular stopwatch.,Results.,The intrarater and interrater reliability (intraclass correlation [ICC][1,1]) ranged from 0.55 to 0.97. The test,retest reliability (ICC[1,1]) ranged from 0.54 to 0.85. The absolute measurement error of the total time (1.96 Sw) was 2.8 seconds. The internal consistency (Cronbach's alpha) was 0.74. The correlation (Pearson's r) between ETUG total time and TUG after correcting for attenuation caused by restricted reliability in each of the measures was 0.85.,Conclusion.,The ETUG scored from a video shows a good reliability for experienced raters and acceptable internal consistency. The ETUG showed a higher reliability than TUG when tested on the same sample of older subjects with impaired mobility, and the high concurrent validity between ETUG and TUG suggests that the two tests may have similar properties. Since ETUG also adds new information compared with TUG, we suggest that ETUG is an interesting alternative to existing clinical tests of mobility. Copyright © 2008 John Wiley & Sons, Ltd.
