Depression is a common health problem in the adolescent population. The Reynolds Adolescent Depression Scale (RADS) is used to measure depression in clinical and community adolescent samples. Although there is available evidence for the reliability and validity of the RADS, there is insufficient documentation of its factor structure. This study examined the factor structure of the RADS in adolescent boys and girls (m-144). Internal consistency reliability ranged from .91 to .94 based on grade level, and was .91 for boys and .93 for girls. Factor analysis resulted in a 5-factor solution. Interpretation of factors were as follows: (a) Factor I—generalized demoralization; (b) Factor II—despondency and worry; (c) Factor III—externalized somatocism; (d) Factor IV—anhedonia; and, (e) Factor V—self-worth.

Objective: The aim of the present study was to examine the reliability and validity of the short form of the Reynolds Adolescent Depression Scale (RADS-SF). Method: A sample of 9567 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey that included the full-length version of the RADS. The reliability and validity of the subset of items that make up the RADS-SF and its comparability to the original version were assessed using Cronbach's alpha, kappa statistics, correlations between the two versions of the instrument, confirmatory factor analysis and correlation to other questions in the survey considered likely to be associated with depression. Results: The RADS-SF had Cronbach's alpha of 0.88, was strongly correlated (0.95) to the RADS, had acceptable fit for the data (χ2=2823.27, df=35, comparative fit index=0.96, root mean square error of approximation=0.092, 90% confidence interval=0.089–0.095, standardized root mean square residual=0.042), showed configural invariance across gender, age and ethnic groups, and was strongly correlated with other depression-related questions, such as suicidal ideation (r=0.48). While the overall agreement for classification of depression by the two scores was good (κ=0.75), a higher percentage of students were classified as having depressive symptoms using the recommended RADS-SF cut-off point of 26 compared with the RADS criteria. Conclusions: The RADS-SF was found to have acceptable reliability and validity and to have psychometric properties comparable to the RADS in a large population of New Zealand adolescents.

Background and Purpose: This study evaluated the psychometric properties of the Perception of Risk Factors for Type 2 Diabetes (PRF-T2DM), an instrument designed to measure awareness and vulnerability to diabetes and diabetes risk factors. Methods: 248 individuals at increased risk for diabetes because of a positive family history completed the PRF-T2DM. The factor-structure, internal consistency reliability, and construct validity of the PRF-T2DM were examined. Results: The 2-factor structure of the PRFT2DM was a good fit to our data. Overall Cronbach's alpha was .68. Pearson correlation between PRF-T2DM score and overall risk perception was significant (r = .26, p < .001). Replies to individual items supported the validity of the PRF-T2DM. Conclusion: The PRF-T2DM performed modestly in this population. Refinement in scoring and score interpretation may improve reliability and validity of the instrument.

Abstract The Parental Bonding Instrument (PBI) evaluates parental attitudes derived from an individual’s childhood experiences with their parents. The factor structure of the PBI differs depending on variables such as psychosocial factors including culture, race, sex, and psychological and social conditions of participants. Although previous studies of the relationship between perinatal depression and parenting experiences have used the factor structures of the PBI from the general population, it is unclear whether the same factor structures are appropriate in the highly variable perinatal period. In this study, complete responses to the PBI and the Edinburgh Postnatal Depression Scale (EPDS) were received from 932 primiparas at 25 weeks of gestation and at 1 month postpartum. An exploratory factor analysis was performed on half of the responses, and it was confirmed that the three factors were care, interference, and autonomy. Confirmatory factor analysis of the remaining half of the answers showed comprehensible fitness. Each factor showed a high degree of internal consistency, and each factor of the PBI correlated with the EPDS, indicating construct validity. The reliability and validity of the PBI in perinatal Japanese women were confirmed, and it was found that the PBI had a three-factor structure.

Background and Purpose: Globally, depressive symptoms are a leading contributor to years lived with disability. The Center for Epidemiological Studies–Depression (CES-D) scale has been used extensively to quantify depression; yet, its psychometric properties remain contentious. This study examined the reliability and factor structure of the CES-D in the MacArthur Foundation’s Midlife in the United States Study (MIDUS), a nationally representative cohort study of noninstitutionalized, English-speaking adults aged 24–74 years. Methods: Internal consistency (Cronbach’s alpha) and confirmatory factor analysis (CFA) were used to examine the reliability and factor structure of the CES-D. Results: There were 1,233 participants who were included in the analysis (mean age = 57.3 years [SD = 11.5], 56.7% female). Cronbach’s alpha of .90 was observed. The 4-factor model had the best model fit. Conclusions: High internal consistency was demonstrated alongside a replication of the original 4-factor structure. Continued use of the CES-D in noninstitutionalized populations is warranted.

The study examined the reliability and validity, including the factor structure, of a 10-item abbreviated version of the Center for Epidemiological Studies–Depression (CES—Depression) scale when administered as part of a mail questionnaire. It also examined patterns of nonresponse to items and the effects of imputation of data for missing items on the factor structure of the inventory. A problem of missing data has been reported even with interview administration of the CES–Depression. Researchers have varied considerably in the amount of imputation used to replace missing datapoints. In this study, factor structures varied when items were imputed. In addition, those subjects with complete data were compared with those with up to two imputed datapoints. Those subjects with imputed data were more likely to be female, have lower functional status scores, lower self-reported health status, more advanced age, and a greater number of depressive symptoms than those with no missing data. While the estimate of coefficient alpha of .78 indicated the inventory was reliable, the effects of missing data on construct validity were problematic.

The reliability and the validity of the standard 21-item form of the Beck Depression Inventory were investigated for a sample of 85 female and 118 male university students. No sex differences were observed. The internal consistency reliability was .82. The Zung Self-rating Depression Scale was used as a congruent depression scale and correlated significantly with the Beck scores ( r = .69). The results indicate a satisfactory reliability and validity for the translated Beck inventory, although the use of a nonclinical sample prevents generalization to clinically depressed populations.

Objective: To examine aspects of the reliability and validity of the Reynolds Adolescent Depression Scale (RADS) in measuring depression in New Zealand adolescents of all major ethnic groups. Method: A sample of 9699 randomly selected New Zealand secondary school students participated in the Youth2000 Health and Wellbeing Survey which included the RADS. Data from this survey have been used to assess some aspects of the reliability and validity of the RADS in the New Zealand context across different ethnic groups. Cronbach's alpha, itemtotal score correlations, correlation to other questions and a factor analysis were done in order to examine the internal reliability, content validity, convergent validity and construct validity of the data and compare to the original Reynolds validation study. Results: Tests of the scale resulted in scores over 0.90 on Cronbach's alpha and high itemtotal score correlations, with a median correlation of 0.62 and 25 of the 30 correlations measuring more than 0.5. The scores were found to have similar factor structure to the original scale and the correlations to other depression related questions indicate acceptable concurrent validity. Conclusions: On all of the tests conducted, the RADS was found to have acceptable reliability and validity for New Zealand adolescents across the major different ethnic groups, indicating that it is a valid and appropriate instrument to use with New Zealand adolescents.

Based on previous factor analyses of child and adolescent depression inventories, the following eight basic dimensions were identified, i.e., Pessimism, Weak Concentration, Sleep Problems, Anhedonia, Fatigue, Loneliness, Low Self-esteem, and Somatic Complaints. Each dimension was assessed by five items, so the Multidimensional Child and Adolescent Depression Scale has 40 brief statements answered on a 3-point intensity scale, i.e., None, Some, and A lot. The eight dimensions have good factorial validity and acceptable to good alpha and test-retest reliability, and good criterion-related validity using three self-report depression scales. The total scale score has from good to high coefficients of reliability and validity. The highest mean scores were on Fatigue and Anhedonia for Kuwaiti boys and girls, respectively, while the Loneliness subscale has the lowest mean score for both sexes. Girls attained significantly higher mean scores than boys for the total score as well as on all dimensions, with the exception of weak concentration. The scale has two compatible Arabic and English versions. It was designed to be useful in defining the profile of children's and adolescents' depression.
