Abstract

The benefits of physical activities on depressive symptoms have increasingly been reported in the literature, but the effect through which a Web-based physical activity promotion program alleviates depressive symptoms is not clearly known, especially among ethnic minority midlife women. The purpose of this pilot randomized control study is to examine the preliminary efficacy of the Web-based physical activity promotion program in enhancing the depressive symptoms of Asian American midlife women through increasing physical activity. This study adopted a randomized repeated measures pretest/posttest control group design. This study consisted of two groups of research participants: 18 in an intervention group and 15 in a control group. By using multiple instruments, the participants’ background and health status, depressive symptom experience, and physical activity experience were measured at three time points (pre-, post 1-month, and post 3-months). The data were analyzed using a modified intent-to-treat linear mixed-model growth curve analysis. After controlling for covariates, random intercept, and random slope, only discrimination stress showed statistical significances in the group effect (0.18, p = .08 for control) and time effect (-0.04, p = .04), but not in the group × time effect (p = .51). The active living habits scores showed statistical significances in the group effect (0.82, p < 0.01 for control), time effect (0.29, p < 0.01), and group × time effect (-0.31, p = 0.03 for control). Findings support the significant effect of the Web-based physical activity promotion program on the women’s discrimination stress and active living habits.
