The concurrent validity of the Beck Depression Inventory (BDI) was evaluated in 122 outpatient adolescents referred to a clinic for depression. Criterion validators were Kiddie-Schedule for Affective Disorders and Schizophrenia (K-SADS) generated diagnoses and a 17-item clinician-rated depression scale extracted from the K-SADS. Initial BDI scores of(More)
Videotaped interrater reliability was assessed with the K-SADS-III-R on 25 children with a mean age of 10:9. Kappa statistics were computed in syndromes with a frequency rate of at least 20%. The following mean kappas were obtained: major depression = 0.83; overanxious disorder = 0.85; separation anxiety = 0.85; simple phobic disorder = 0.64; oppositional(More)
Beck Depression Inventory (BDI) scores of 328 adolescents referred to a depression clinic were factor analyzed to test the discriminant validity of each factor. Three of the four factors (Negative Self Attitude.

The U.S. Naval Research Laboratory develops and maintains a freely available IPv6 and IP Security distribution. All of the software builds and runs on BSD/OS, FreeBSD, NetBSD, and OpenBSD, and a growing portion of the software builds and runs on Linux. Each of the four BSDs has evolved signiicantly from their original 4.4BSD-Lite ancestor, and increasingly(More)
