title: Self-presentation and physical activity in breast cancer survivors: the moderating effect of social cognitive constructs.
abstract: This study examined (1) the relationships between self-presentation processes (i.e., impression motivation and impression construction) and moderate-to-vigorous physical activity (MVPA) among breast cancer survivors, and (2) whether social cognitive constructs (i.e., self-presentational efficacy expectancy [SPEE]; self-presentational outcome expectancy [SPOE]; self-presentational outcome value [SPOV]) moderate these relationships. Breast cancer survivors (N = 169; Mage = 55.06, SD = 10.67 years) completed self-report measures. Hierarchical regression analysis, controlling for age and body mass index, indicated that impression motivation was a significant correlate of MVPA (β = .25). Furthermore, SPEE (β = .21) and SPOV (β = .27) were moderators of this relationship. The final models accounted for 12-24% of the variance in MVPA. The findings of this study suggest that self-presentation processes (i.e., impression motivation) may indeed relate to breast cancer survivors' MVPA. In addition, social cognitive constructs (i.e., SPEE, SPOV) moderated the relationship between impression motivation and MVPA. It may be effective to target impression motivation, SPEE, and SPOV in interventions aimed at increasing MVPA among breast cancer survivors.
