Figure 1.

Schematic diagram of the results of mediation by task self-efficacy on moderate-to-vigorous physical activity. Shown are the path coefficients between intervention condition, task self-efficacy at 24–28 weeks, and moderate to vigorous physical activity (MVPA) at 24–28 weeks (A) and at 35–37 weeks (B). Statistically significant path coefficients are shown in bold and with solid lines. Dashed lines indicated non-significant paths. Indirect effects were calculated as the product of the coefficients of the a and b paths (a × b).
