Forty female undergraduates were randomly assigned to one of four stress-inducing conditions: one group was given a defensive strategy in the form of denial, rationalization, and intellectualization self-statements (Film S-T); a second was given self-statements designed to help them control their arousal (Arousal S-T); a third group was given relevant information about the nature of the film (Info); and a fourth group was given no relevant information (Control). Measures of self-report of anxiety, cognitive coping techniques, and heart rate were examined during the anticipatory period and throughout the film period. Arousal and Film S-T subjects were significantly more physiologically aroused while anticipating the film, and Control and Info subjects reported higher levels of anxiety due to the film. The relevance of anxiety thoughts made by some subjects prior to the stressor was found to be significantly related to the amount of worry and apprehension reported both while anticipating and during the stressful film. The study provided partial support for the "work of worrying" concept described by Janis and elaborated upon by Meichenbaum. These findings and their implications were discussed. (Author)
