Assessment of depression in childhood and adolescence: an evaluation of the Center for Epidemiological Studies Depression Scale for Children (CES-DC).

Psychometric characteristics of the Center for Epidemiological Studies Depression Scale for Children (CES-DC) were evaluated with 148 child and adolescent psychiatric inpatients. Test-retest reliability, internal consistency, and concurrent validity were adequate. Principal components analysis identified three distinct factors: behavioral and cognitive components of depression and a happiness dimension.

Social reinforcement and the naturally occurring social responses of severely and profoundly retarded adolescents.

This study was designed to determine if the deficits in social behavior of retarded persons might be due, in part, to the failure of their environment to maintain that behavior. Using an ABAB design, we systematically ignored severely and profoundly retarded, institutionalized adolescents and gave them social reinforcement for appropriate social behavior. Social behavior decreased during nonreinforcement conditions and increased during reinforcement conditions.
