本研究探讨了完成体力活动干预后运动维持的预测因素。通过报纸广告招募的久坐不动的成年人被随机分配接受（a）动机匹配的干预与反馈报告，这些反馈报告是通过计算机专家系统根据社会认知理论和跨理论模型中的心理变量单独定制的（IT），或（B）标准的基于打印的干预（ST）。研究的干预阶段包括基线时的邮寄评估和干预材料。1、3、6个月。干预结束后6个月（第12个月）进行仅评估随访。对参与者进行了评估，包括当前的身体活动参与、身体活动的动机准备、一些影响身体活动参与的心理结构（例如，自我效能（self-efficacy）和当前影响。值得注意的是，与ST参与者相比，IT条件下更多的参与者在干预期结束时达到或超过了运动参与目标，并在第12个月随访时保持了这种身体活动水平。前瞻性分析显示，在项目进入（基线）和干预期结束时，在12个月内保持体力活动参与的个体与未保持体力活动参与的个体之间，几种心理结构存在显著差异。结果表明，维持体力活动结束后的积极干预计划可能会受到态度和行为获得沿着增加参与体力活动，以及预先存在的特征，个人带入治疗。
This study examined predictors of exercise maintenance following completion of a physical activity intervention. Sedentary adults recruited through newspaper advertisements were randomly assigned to receive either (a) a motivation-matched intervention with feedback reports that were individually tailored (IT) to psychological variables from social cognitive theory and the Transtheoretical Model via computer expert system, or (b) a standard, print-based intervention (ST). The intervention phase of the study included mailed assessments and intervention materials at baseline. 1, 3, and 6 months. An assessment-only follow-up was conducted 6 months after the end of the intervention (Month 12). Participants were assessed for current physical activity participation, motivational readiness for physical activity, a number of psychological constructs posited to influence participation in physical activity (e.g., self-efficacy), and current affect. Significantly, more participants in the IT condition met or exceeded exercise participation goals at the end of the intervention period and maintained this level of physical activity through the Month 12 follow-up compared to ST participants. Prospective analyses revealed significant differences in several psychological constructs both at program entry (baseline) and the end of the intervention period between individuals who maintained their physical activity participation through Month 12 and those who did not. Results suggest that the maintenance of physical activity following the end of an active intervention program may be influenced by attitudes and behaviors acquired along with increased participation in physical activity as well as by preexisting characteristics that individuals bring into treatment.
