Schizophrenia Quality of Life Scale: validation of the Japanese version

This study was performed to test the validity and value of the Schizophrenia Quality of Life Scale as an assessment tool in a Japanese-language version (JSQLS). The subjects for the present study were 55 inpatients with a diagnosis of schizophrenia as defined by DSM-IV. The JSQLS was administered together with two other self-report measures, the Medical Outcomes Study 36-item short-form health survey questionnaire (SF-36) and the WHO QOL-26, to assess validity. Psychotic symptoms and extrapyramidal symptoms were assessed using the BPRS and the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS), respectively. All the scales (psychosocial, motivation/energy and symptoms/side effects) showed good internal consistency reliability (Cronbach's alpha=0.93, 0.73 and 0.80, respectively). The correlations of items with their scale total revealed that almost all items were significantly correlated with their own scale score. There were associations with relevant SF-36, WHO QOL-26, and DIEPSS scores. From the results of the testing of the reliability and validity of the JSQLS, it is concluded that the JSQLS is a simple and reliable scale.     

Internal consistency and test-retest reliability of the Chinese version of the self-report health-related quality of life measure for children and adolescents with epilepsy

PURPOSE: The aim of this validation study was to evaluate the internal consistency (internal reliability) and test-retest reliability (external reliability) of the Chinese version of the self-report health-related quality of life measure for children and adolescents with epilepsy. METHODS: Children and adolescents with epilepsy between the ages of 8 and 18 years were conveniently sampled in two regional hospitals in Hong Kong. They were requested to complete the 25-item questionnaire twice, with a test-retest interval of 10 to 14 days. Internal consistency and test-retest reliability were measured with Cronbach's alpha coefficient and the intraclass correlation coefficient, respectively. RESULTS: A sample of 50 patients completed the first questionnaire. Internal consistency was adequate on four of five subscales and marginal in the remaining one. Forty-two subjects repeated the questionnaire. The test-retest reliability was acceptable for all five subscales. CONCLUSIONS: The Chinese version of the health-related quality of life measure for children and adolescents with epilepsy demonstrated acceptable internal consistency and test-retest reliability. Further studies are required to study other psychometric properties such as construct validity and factor analysis.     

The Persian Version of a Participation Scale: Is It Valid and Reliable Enough for Use among Iranian Patients with Multiple Sclerosis?

MethodsTrained experts interviewed 364 MS patients and their relatives to assess the criterion validity, stability reliability, and internal consistency of the IPA-p scale. Ten specialists from different disciplines were also recruited to assess its face validity. A consent form was completed by the patients and their relatives. Internal consistency reliability was measured using Cronbach''s alpha and stability reliability was assessed using interclass correlation coefficients (ICCs). The test-retest method was used to detect the reliability of the questioner. The study subjects completed the IPA-p scale on two occasions separated by an interval of 30-45 days. Study checklists were also used to assess the face validity, stability reliability, and internal consistency of the IPA-p scale.ResultsAbout 50% of the respondents reported their perceived overall participation to be "good" or "very good" and 60% of the specialists rated the ability of the IPA-p scale to measure what it was designed for as "excellent." Spearman correlation coefficients were >0.8 for all but one IPA-p domain. Cronbach''s alpha between the mean IPA-p scale scores achieved on two separate occasions ranged from 0.858 to 0.913. The highest and lowest internal consistencies belonged to the "social relationships" and "education and learning" domains, respectively. The test-retest ICCs for the nine domains were between 0.789 and 0.919, and all were significant at p<0.001.ConclusionsThe IPA-p questionnaire can be considered a valid and reliable instrument for assessing self-reported participation among Iranian MS patients.     

The validity and reliability of the Turkish version of Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) in patients with mild and moderate Alzheimer's disease and normal subjects

OBJECTIVES: The cognitive subscale of the Alzheimer's Disease Assesment Scale (ADAS-Cog) is the most widely used test in clinical trials dealing with Alzheimer's disease (AD). The aim of this study was to investigate the validity and reliability of the Turkish version of ADAS-Cog. METHODS: Twenty-nine patients with AD, fulfilling NINCDS-ADRDA criteria of probable AD, who were in stage 3-5 according to the Global Deterioration Scale (GDS), and 27 non-demented control subjects with similar age, gender and educational status were recruited for the study. The Turkish version of ADAS-Cog, Standardized Mini Mental Status Examination (MMSE) and Short Orientation-Memory-Concentration Test (SOMCT) were applied to both of the groups. Inter-rater reliability, internal consistency, test-retest reliability; face validity, differential validity and convergent validity were statistically analyzed. RESULTS: Both MMSE and ADAS-Cog have significantly differentiated patients with AD and control subjects (p < 0.001). A significant correlation was established between MMSE and ADAS-Cog scores in AD group (r: -0.739). ADAS-Cog was also highly significantly correlated with GDS (r: 0.720) and SOMCT (r: 0.738). For the group with AD, control and whole cohort coefficients of internal consistency, Cronbach's alpha: 0.800, 0.515, 0.873 were found respectively. Inter-rater reliability for total ADAS-Cog score was found as ICC: 0.99 and 0.98 and test-retest reliability was found as ICC: 0.91 and 0.95 for demented and nondemented subjects, respectively. CONCLUSION: The Turkish version of ADAS-Cog has been found to be highly reliable and valid in differentiating patients with mild and moderate AD from nondemented subjects.     

Quality of life assessment in schizophrenia: applicability of the Lehman Quality of Life Questionnaire (TL-30)

The aim of the present study was to investigate the applicability of a quality of life self-rating scale - the Lehman Quality of Life Questionnaire TL-30 - to evaluate the test-retest reliability of the TL-30 and finally to test the quality of life in schizophrenic patients compared with a general population. Patients with ICD-10 F20 schizophrenia were included. An interviewer-administrated quality of life instrument, the Lehman's QoLI interview guide, and two questionnaires, the Lehman TL-30 and the Medical Outcome Study (SF-36) were used at baseline. Hereafter the two questionnaires were completed again 2 weeks after discharge from hospital for the evaluation of test-retest reliability. A total of 56 patients were interviewed and 40 patients (or 71%) completed the questionnaires. Statistically significant correlation was found between the interview form and the questionnaire version. The test-retest coefficients were at the same level (approximate 0.70 for most Lehman subscales) as found for the SF-36 subscales. Compared with the general population, lower health-related quality of life (SF-36) was found in schizophrenia (P<0.01). The results of the present study confirm that the Lehman Quality of Life questionnaire can be validly used in stable schizophrenics.     

Reliability and validity of the substance abuse outcomes module

OBJECTIVE: The study sought to determine the validity and reliability of the Substance Abuse Outcomes Module (SAOM), a self-report tool designed to assess patient characteristics, process of care, and outcomes of care, using a minimum amount of information, in order to improve treatment. METHODS: A longitudinal field test (baseline and three-month follow-up) compared the SAOM to seven other research instruments in the assessment of 100 substance-abusing patients who were entering a new treatment episode. Quota samples of patients were drawn from two private inpatient substance abuse treatment facilities and an outpatient methadone clinic. The study's primary outcome measures were diagnostic accuracy, internal and test-retest reliability of key constructs, concurrent and predictive validity, and sensitivity to change. Cronbach's alpha coefficients were calculated to examine internal consistency and reliability. Intraclass correlation coefficients and kappa coefficients were used to examine test-retest reliability. Concurrent validity of outcomes measures was examined with Pearson or Spearman correlation coefficients and chi square and kappa statistics. Changes between baseline and follow-up were examined as a function of case-mix measures with ordinary least-squares multiple regression. Sensitivity to change was examined by calculating effect size scores. RESULTS: The SAOM had high internal consistency and a high level of agreement with research diagnoses at baseline and follow-up. The SAOM was found to be highly reliable, to have very strong validity, and to be sensitive to clinical change. CONCLUSIONS: The SAOM appears to be a reasonably reliable and valid self-report instrument when used to monitor substance abuse treatment among patients with a primary substance use diagnosis.

Evaluation of the psychometric characteristics of the Spanish version of the Hospital Anxiety and Depression Scale

OBJECTIVE: To assess the psychometric properties of the Spanish version of the Hospital Anxiety and Depression Scale(HADS). METHOD: We administered HADS to 685 participants (256 controls and 429 patients with five different diagnoses). The reliability of the instrument was assessed by a test-retest study. Construct validity studies were carried out through item-subscale correlation and factor analysis for the whole group and by each of the five different diagnoses. Three instruments were used as external criteria to assess concurrent validity. RESULTS: HADS test-retest reliability presented correlation coefficients above 0.85. The internal consistency was high, with a Cronbach's alpha of 0.86 (anxiety) and 0.86 (depression). Factor analysis showed a clear two-factor structure for all groups. The results showed high concurrent validity with the Beck Depression Inventory and State-Trait Anxiety Inventory and with the mental domains of the Short-Form Health Survey. CONCLUSION: The Spanish version of the HADS demonstrated good reliability and validity when used in medical patients.
