Article: [Agreement of clinical diagnosis, structured interviews, and self-report questionnaires for depression in children and adolescents].
[show abstract] [hide abstract]
ABSTRACT: Objective: The present study examines the agreement of structured child and parent interviews as well as clinical diagnosis for depressive episodes in children and adolescents. Moreover, it compares the accuracy and optimal cutoff scores of self-report questionnaires with reference to each of these diagnostic assessments. Method: 81 children (9-12 years) and 88 adolescents (13-16 years) in psychiatric care and their parents completed the structured diagnostic interview Kinder-DIPS. The children answered the German Children's Depression Inventory (CDI), and the adolescents answered the German Center for Epidemiologic Studies Depression Scale (CES-D). Kappa coefficients quantified the agreement. Receiver operating characteristic (ROC) curves were used to determine optimal cutoff scores, sensitivity, specificity, as well as positive and negative predictive values. Results: The agreement between the child and parent interviews as well as between the interviews and clinical diagnosis was low to moderate. Clinicians diagnosed depressive episodes more frequently than the interviews. Cutoff scores and measures of accuracy varied between the reference standards, with less favorable results for clinical diagnosis. Conclusions: Clinicians may profit from conducting structured interviews. Strategies for dealing with conflicting information from children and parents should be tested empirically and described in detail.Zeitschrift für Kinder- und Jugendpsychiatrie und Psychotherapie 11/2012; 40(6):405-14. · 0.99 Impact Factor -
Article: The Beck Depression Inventory-II in adolescent mental health patients: Cut-off scores for detecting depression and rating severity.

ABSTRACT: The Beck Depression Inventory-Second Edition (BDI-II) was developed as an indicator of the presence and severity of depression in psychiatric patients from age 13. Its cut-off scores were derived from an adult sample and differentiate four categories of severity but contain no screening cut-off score for classifying patients as depressed vs. nondepressed. We aimed to determine this screening cut-off score and to examine the utility of the severity cut-off scores for adolescents in mental health care. 88 adolescent psychiatric patients (13-16 years, 58% female) completed the German BDI-II. A structured diagnostic interview served as the reference standard for computing receiver operating characteristic (ROC) curves and identified 24 adolescents (27%) as depressed. ROC analysis of depressed vs. nondepressed patients yielded an area under the curve (AUC) value of 0.93. The optimal screening cut-off score according to Youden's Index was ≥23, where sensitivity was 0.88 and specificity was 0.92. The severity cut-off scores yielded satisfying sensitivity (≥0.89) and specificity (≥0.72) for mild and moderate but not for severe depression. Our findings indicate that the BDI-II can be recommended for screening for depressive disorders in adolescent mental health patients. However, the currently used severity cut-off scores may be suboptimal for this population.Psychiatry Research 05/2012; · 2.52 Impact Factor
