- AIM: Examination of psychometric properties and diagnostic accuracy of the Depression Self-Rating Scale for Adolescents (DSRS-A) as well as development and evaluations of a shorter version, DSRS-A-Screener.METHODS: Analyses of component structure and internal consistency were performed in a community-based sample of adolescents N = 4,506 and among consecutive outpatients from three child psychiatric settings in Sweden (n = 137). Concurrent validity was measured as a correlation between a summation index of the scale items and the total major depressive disorder (MDD) symptom severity score from the Kiddie Schedule of Affective Disorders and Schizophrenia (K-SADS). Diagnostic accuracy was examined in the clinical sample, with the K-SADS interview as the reference test, by receiver operating characteristic analysis (ROC), calculations of sensitivity, specificity among other measures. With the purpose to select items for a shorter scale, associations between scale items and MDD were examined with binary logistic regression. This shorter scale was thereafter examined similarly.RESULTS: Based on association with MDD, five items were selected for the brief DSRS-A Screener that showed one component structure, internal consistency Cronbach's alpha .80 and.82, respectively. In the clinical population concurrent validity was Spearman's rho .63 and ROC analysis showed AUC .84 (95% CI .78-.91; p < .001). The optimal cut-off for screening was 2 with sensitivity .85 and specificity of .64.CONCLUSION: The DSRS-A Screener compared to the original scale, maintained or improved reliability, validity, and showed moderate diagnostic accuracy.

- Background: The World Health Organization Adult ADHD Self Report Scale (ASRS) is a widely used diagnostic tool for assessment of attention-deficit hyperactivity disorder (ADHD) symptoms in clinical psychiatry in Sweden. The ASRS consists of 18 questions, the first six of which can be used as a short screening version (ASRS-S). There is a version for adolescents—ASRS-Adolescent (ASRS-A)—and the corresponding screening version (ASRS-A-S), which has not been validated to date.Aim: The aim was to validate the ASRS-A and the ASRS-A-S for use in adolescent clinical populations.Methods: Adolescent psychiatric outpatients (n = 134, mean age 15 years, 40% boys) reported on the ASRS-A, and were interviewed with the Kiddie Schedule of Affective Disorders and Schizophrenia (K-SADS), a semi-structured interview, together with a parent.Results: Internal consistency was 0.79 for the ASRS-A-S and 0.92 for the ASRS-A (Cronbach's alpha). Internal consistency values were 0.79 and 0.87 for the inattention subscale, and 0.68 and 0.89 for the hyperactivity subscale, respectively. Concurrent validity values, measured with Spearman's correlation coefficient, between the total K-SADS ADHD symptom severity score and the sum of ASRS-A-S and ASRS-A total scores were 0.51 and 0.60, respectively. Psychometric properties of the ASRS-A-S and the ASRS-A were: sensitivity 74% and 79%; negative predictive value 81% and 84%; specificity 59% and 60%; and positive predictive value 49% and 51%, respectively. Both versions showed better properties for girls than for boys.Conclusion: Both the ASRS-A-S and the ASRS-A showed promising psychometric properties for use in adolescent clinical populations.
