Recent research indicates that females are particularly likely to lack confidence in their abilities to perform physical activities. One theory of instruction suggests a need for educational support for developing competence, self-confidence, and persistence in physical activities. Vicarious success in the form of audiovisual presentations is suggested as one method of educational support which may be effective in enhancing confidence, particularly among females. Thirty-nine adult women participating in an exercise class were studied to determine if vicarious success presented via audiovisuals was effective in altering self-confidence, commitment to physical activity, and physical activity involvement. A discriminant function analysis indicated a significant difference between treatment and control groups on a profile of improved confidence/attitude/activity involvement, with the treatment group showing a more positive profile. Vicarious success experiences enhanced self-confidence, and there was a trend toward greater persistence in activity among those experiencing vicarious success through audiovisual presentations.
