To investigate the effects of viewing various films on affect, 200 volunteer subjects were assigned to 10 groups following a modified Solomon four-group design. Five groups received pretesting and five groups received no pretesting before being exposed to one of five treatments and follow-up testing 2 or 3 wk. later with the State Form of the Multiple Affect Adjective Check List and the Depression Check List. The treatments required viewing films of an actor who conveyed depression, positive affect, and neutral affect, and a no-film control. Subjects viewing a film were administered 13 semantic differential adjective pairs to obtain the observers' perception of the character in the film and the California Psychological Inventory. Depression increased following the depressed and neutral film conditions, and decreased from posttest to follow-up test, while the positive and no-film control conditions produced no change from pretest to posttest levels of depression. Similar results were found for the measure of anxiety but not for hostility. Subjects tended to be affected in the same way by the treatments regardless of their pretreatment levels of depression, anxiety, or hostility. Relationships between the changes in depression from pre-to posttest and personality variables were not confirmed.
