Conducted a study to evaluate treatment interventions that may alleviate depression among incarcerated felons. 10 inmates at a large maximum-security prison were randomly assigned to group cognitive therapy or individual supportive treatment plus brief counseling contacts. Analysis indicated statistical and clinical significance on measures of depressive symptomatology for treatment conditions across the periods of assessment. Findings support the utility of depression-treatment programs for prisoners. Moreover, the treatment modalities are presented along a variety of dimensions, which may be useful when considering such interventions at facilities where psychological services are limited.
