Diagnostic Interview for Genetic Studies (DIGS): inter-rater and test-retest reliability and validity in a Spanish population.

OBJECTIVE: To test the reliability and validity of the DIGS in Spanish population. METHODS: Inter-rater and test-retest reliability of the Spanish version of DIGS was tested in 95 inpatients and outpatients. The resultant diagnoses were compared with diagnoses obtained by the LEAD (Longitudinal Expert All Data) procedure as "gold standard". The kappa statistic was used to measure concordance between blind inter-raters and between the diagnoses obtained by LEAD procedure and through the DIGS. RESULTS: Overall kappa coefficient for inter-rater reliability was 0.956. The kappa value for individual diagnosis varied from major depression=0.877 to schizophrenia=1. Test-retest reliability was 0.926. Kappa for all individual target diagnoses ranged from 0.776 (major depression) to 1. Kappa between LEAD procedure and DIGS ranged from 0.704 (major depression) to 0.825 (bipolar I disorder). CONCLUSION: Most of the DSM-IV major psychiatric disorders can be assessed with acceptable to excellent reliability with the Spanish version of the DIGS interview. The Spanish version of DIGS showed an acceptable to excellent concurrent validity. Giving the good reliability and validity of Spanish version of DIGS it should be considered to identify psychiatric phenotypes for genetics studies.     

Assessment of the severity of dementia: validity and reliability of the Chinese (Cantonese) version of the Hierarchic Dementia Scale (CV-HDS)

BACKGROUND: With the rapid growth of the older population, early detection of cognitive deficits is crucial in slowing down functional deterioration of the elderly persons. OBJECTIVES: To examine the validity and reliability of the Chinese (Cantonese) version of the Hierarchic Dementia Scale (CV-HDS) for Chinese older persons in Hong Kong. METHODS: The HDS was translated into Cantonese Chinese. The content and cultural validity were evaluated by six expert panel members. Sixty-two participants with diagnosis of dementia were recruited for evaluation. Inter-rater reliability, test-retest reliability, internal consistency and concurrent validity were examined. RESULTS: The CV-HDS demonstrated satisfactory psychometric properties. inter-rater reliability and test-retest reliability were high (alpha = 0.89 and alpha = 0.94 respectively). High value of Cronbach's alpha (alpha = 0.94) demonstrated good internal consistency. The concurrent validity of CV-HDS, through correlation with its scores with that of the Chinese version of Mini Mental Status Examination, was established (ranged from r = 0.58 to r = 0.78, p < 0.01). CONCLUSIONS: The CV-HDS is a reliable and valid instrument for assessing severity of cognitive impairment in Cantonese speaking Chinese people with dementia. It facilitates treatment planning to optimize the effects of functional training and rehabilitation. Copyright (c) 2008 John Wiley & Sons, Ltd.     

The validity and reliability of chinese frontal assessment battery in evaluating executive dysfunction among Chinese patients with small subcortical infarct

OBJECTIVES: Frontal Assessment Battery (FAB) is a valid and reliable screening test for evaluating executive dysfunction among whites with frontal and subcortical degenerative lesions. We studied the properties of a Chinese version of FAB (CFAB) in evaluating executive dysfunction among Chinese stroke patients with small subcortical infarct. METHODS: Concurrent validity was evaluated using Wisconsin Card Sorting Tst (WCST) and Mattis Dementia Rating Scale-Initiation/Perseveration Subset (MDRS I/P) among 41 controls and 30 stroke patients with small subcortical infarct. Discriminant validities of CFAB and its subitems were compared with those of Mini-Mental State Examination (MMSE). Internal consistency, test-retest, and interrater reliability of CFAB were evaluated. RESULTS: The CFAB had low to good correlation with various executive measures: MDRS I/P (r = 0.63, p < 0.001), number of category completed (r = 0.45, p < 0.001), and number of perseverative errors (r = -0.37, p < 0.01) of WCST. Among the executive measures, only number of category completed had significant but small contribution (6.5%, p = 0.001) to the variance of CFAB. A short version of CFAB using three items yielded higher overall classification accuracy (86.6%) than that of CFAB full version (80.6%) and MMSE (77.6%). Internal consistency (alpha = 0.77), test-retest reliability (rho = 0.89, p < 0.001), and interrater reliability (rho = 0.85, p < 0.001) of CFAB were good. CONCLUSION: Although CFAB is reliable, it is only moderately valid in evaluating executive dysfunction among Chinese stroke patients with small subcortical infarct. The clinical use of CFAB in the evaluation of executive dysfunction among this group of patients cannot be recommended at this stage.

Assessment of physical activity in middle-aged and older adults with schizophrenia

BACKGROUND: Regular physical activity (PA) decreases morbidity in the general population; yet, information about the amount and effects of PA in persons with schizophrenia is scant. To develop interventions to increase PA and to assess its potential benefits in this group, accurate measurement of PA is needed. The purpose of this study was to characterize PA and determine the test-retest reliability and concurrent validity of the Yale Physical Activity Scale (YPAS), a self-report measure, in persons with schizophrenia. METHODS: PA was assessed with the YPAS, a scale of motivational readiness for PA, and accelerometry in middle-aged and older persons with a diagnosis of schizophrenia (n=54) and in a comparison group with no known psychiatric diagnosis (n=27). RESULTS: On the YPAS measures, persons with schizophrenia reported on average 11 h per week of PA, whereas the non-psychiatric comparison group reported about 32 h per week. Only about 30% of schizophrenia subjects were classified as being regularly active relative to 62% of the comparison group on PA motivational stages of readiness. On the accelerometry measures, the schizophrenia group had lower levels of light activity than the comparison group, but there were no differences in moderate and vigorous activity or sedentary behavior. Only in the comparison group were there significant associations between YPAS and accelerometer variables. Several YPAS scores demonstrated high test-retest reliability in both groups, and concurrent validity was supported between the YPAS and PA motivational stages of readiness. CONCLUSIONS: We found that the YPAS is a reliable measure of PA in schizophrenia for some indices. Although the YPAS demonstrated concurrent validity with other self-report measures, it did not demonstrate concurrent validity when compared to PA measured by accelerometry in persons with schizophrenia. Use of multiple measures, both subjective and objective, is recommended when assessing PA in schizophrenia.     

Validation of the Chinese version of the Liverpool Adverse Events Profile in patients with epilepsy

The objective of the study was to validate the Chinese version of The Liverpool Adverse Events Profile (LAEP) in patients with epilepsy. The scale was translated from the English version into a Chinese version and was then back-translated to examine its accuracy. Content validity, concurrent validity, and construct validity were then used to examine the overall validity of this scale. A cross-sectional design with convenience sampling was used to recruit participants from three medical centers. The LAEP Chinese version was tested with respect to validity and reliability in 357 patients with epilepsy, and another 28 patients were invited to evaluate the test-retest reliability of the scale in a 2-week interval. There was a good content validity index (CVI=1.0). Patients undergoing polytherapy had more adverse effects (χ(2)=6.10, p<0.01) and higher LAEP scores (t=-2.91, p<0.01) than patients undergoing monotherapy, indicating a good concurrent validity. Factor analysis included three factors classified by symptoms in the 22-item Chinese version of the LAEP. The total variance of these three factors was 39.3% for the scale. Internal consistency (Cronbach's α=0.92) and the intraclass correlation coefficient (ICC=0.80) were satisfactory. Moreover, the LAEP can be completed in a short time, is perceived as easy to complete, and there was no relevant information missing. The results indicated that the Chinese version of the LAEP yielded highly acceptable parameters of validity and reliability and can be used for measuring adverse effects of antiepileptic drugs among Chinese-speaking patients with epilepsy in Taiwan.     

Validation of the virtual-reality prospective memory test (Hong Kong Chinese version) for individuals with first-episode schizophrenia

This study was performed to examine the psychometric properties of a Virtual-Reality Prospective Memory Test (Hong Kong Chinese version; VRPMT-CV). The VRPMT was administered to 44 individuals with first-episode schizophrenia. The test was administered again 2 weeks later to establish test-retest reliability. The concurrent validity of the VRPMT was evaluated by examining the correlations between the VRPMT score and the score on the Chinese version of the Cambridge Prospective Memory Test (CAMPROMPT-CV). The performance of individuals with schizophrenia on the VRPMT was also compared with that of 42 healthy control subjects to examine the test’s sensitivity and specificity. The intraclass correlation for test–retest reliability of the total VRPMT–CV score was 0.78 (p?=?.005). A significant correlation was found between the total VRPMT-CV score and the total CAMPROMPT-CV score (r?=?0.90; p?相似文献   

Reliability and validity of the Korean version of the Scale for the Assessment of Thought,Language, and Communication

BackgroundOur study aimed to assess the inter-rater and test-retest reliability, as well as concurrent and convergent validity, of the Korean version of the Scale for the Assessment of Thought, Language, and Communication (TLC scale).MethodsThe factor solutions and psychometric properties of the Korean version of the TLC scale were evaluated among 167 schizophrenia inpatients (study subjects) at two sites in South Korea. Using Pearson’s correlation, the concurrent and convergent validities of each of the factor solutions were represented by the correlations with the scores on the Clinical Language Disorder Rating Scale, Brief Psychiatric Rating Scale, Young Mania Rating Scale, and Calgary Depression Scale. Using receiver operating characteristics curves, the optimal cut-off score for the Korean version of the TLC scale to distinguish between study subjects with and without disorganized speech, was identified.ResultsThe results showed that the Korean version of the TLC scale has a three-factor solution: fluent disorganization, speech emptiness, and speech peculiarity. In addition, the interrater reliability of the Korean version of the TLC scale was moderately good (intraclass correlation coefficient = 0.51) and its test-retest reliability was very good (Pearson’s correlation coefficient = 0.94). For detecting the current presence of disorganized speech, the optimal cut-off total score on the TLC scale was proposed to be 8 points (sensitivity = 88.1%; specificity = 82.9%).LimitationsPsychometric tools covering cognitive functions were not used in our study.ConclusionsThe Korean version of the TLC scale is a promising psychometric method for examining formal thought disorder (FTD) and disorganized speech in schizophrenia patients.     

Reliability and validity of the Chinese version of Narcolepsy Severity Scale in adult patients with narcolepsy type 1

ObjectiveTo evaluate reliability and validity of the Chinese version of Narcolepsy Severity Scale (NSS) in adult patients with narcolepsy type 1 (NT1).MethodsOne hundred and fifty-one adult patients (≥18 years) with NT1 were recruited. All filled out the 15-item Chinese version of NSS. Item analysis included critical ratio and correlation analysis. The validity of NSS was assessed by exploratory factor analysis, discriminant validity and convergent validity. Reliability of NSS was assessed by Cronbach's α coefficient, spilt-half reliability and test-retest reliability.ResultsCritical value of all 15 items ranged from 3.01 to 13.36. Each item was significantly correlated with the total score by a correlation coefficient (r) ranging from 0.219 to 0.700. Three common domains were extracted and 15 items explained 54.86% of the total variance. There was a shift in domains compared to the English version likely due to cultural differences. Cronbach's α coefficient for the total scale of 15 items was 0.821 and for three factors was 0.726, 0.748 and 0.760 respectively. The NSS had good correlation with Epworth sleepiness scale scores, Insomnia severity index scores and moderate correlation with mean the sleep latency of polysomnographic recording, and European Quality of Life-5 Dimensions Questionnaire. The Chinese version of NSS showed good spilt-half reliability and test-retest reliability.ConclusionThe Chinese version of NSS shows satisfactory psychometric properties with good validity and reliability. It is applicable to evaluate the severity and consequences of symptoms in Chinese adult patients with NT1.
