大多数健康行为模型没有区分行为采纳和维持的决定因素。本研究比较了205名最初久坐不动的成年人参加以家庭为基础的PA推广试验的心理社会预测因素的身体活动（PA）的采用和预测PA的维护。在6个月时测量心理社会变量（此时107名参与者保持不活动，98名参与者采用常规PA），并用于预测12个月的PA状态（6个月时不活动者采用PA的指标和6个月时活动者维持PA的指标）。6-6个月的PA状态调节了6个月的家庭使用PA设备（p = .049），自我效能（p = .086）和感知满意度（p = .062）与12个月PA状态之间的关系。简单的效应分析显示，家庭使用PA设备是PA采用的预测因素（OR = 1.73; 95% CI：1.05，2.85），但不是PA维持（OR = 0.88; 95%CI：0.58，1.35），而自我效能和感知满意度预测PA维持（OR = 2.65; 95% CI：1.55，4.52; OR = 1.95; 95% CI：0.93，4.06），但未采用PA（OR = 1.50; 95% CI：0.87，2.57; OR = 0.82，CI：0.44，1.52）。结果表明，这些心理社会变量可能在预测PA采用与维护不同。
Most health behavior models do not distinguish between determinants of behavior adoption and maintenance. This study compared psychosocial predictors of physical activity (PA) adoption and predictors of PA maintenance among 205 initially sedentary adults enrolled in a home-based PA promotion trial. Psychosocial variables were measured at 6 months (at which point 107 participants remained inactive and 98 participants adopted regular PA) and used to predict 12-month PA status (an indicator of PA adoption among those inactive at 6 months and an indicator of PA maintenance among those active at 6 months). 6-month PA status moderated the relationships between 6-month measures of home access to PA equipment (p = .049), self-efficacy (p = .086), and perceived satisfaction (p = .062) and 12-month PA status. Simple effects analyses revealed that home access to PA equipment was predictive of PA adoption (OR = 1.73; 95% CI: 1.05, 2.85), but not PA maintenance (OR = 0.88; 95% CI: 0.58, 1.35), whereas self-efficacy and perceived satisfaction were predictive of PA maintenance (OR = 2.65; 95% CI: 1.55, 4.52; OR = 1.95; 95% CI: 0.93, 4.06), but not PA adoption (OR = 1.50; 95% CI: 0.87, 2.57; OR = 0.82, CI: 0.44, 1.52). Results suggest that these psychosocial variables may operate differently in predicting PA adoption versus maintenance.
