PURPOSE
The aim of this study was to examine whether the efficacy of transtheoretical model (TTM)-based interventions on physical activity (PA) varied according to the following criteria: (1) interventions targeted the actual stages of change (SOCs) or did not; (2) participants were selected according to their SOC or were not; and (3) its theoretical constructs (decisional balance, temptation, self-efficacy, processes of change).
METHODS
Thirty-three randomized controlled trials assessing TTM-based interventions promoting PA in adults were systematically identified.
RESULTS
The between-group heterogeneity statistic (Qb) did not reveal any differential efficacy either in interventions targeting the actual SOC compared with those that did not (Qb = 1.48, = 0.22) or in interventions selecting participants according to their SOC compared with those that did not (Qb = 0.01, = 0.91). TTM-based interventions enhanced PA behavior whether they targeted the actual SOC (Cohen's = 0.36; 95% confidence interval (CI): 0.22-0.49) or not ( = 0.23; 95%CI: 0.09-0.38) and whether they selected their participants according to their SOC ( = 0.33; 95%CI: 0.13-0.53) or not ( = 0.32; 95%CI: 0.19-0.44). The moderators of the efficacy of TTM-based interventions were the number of theoretical constructs used to tailor the intervention (Qb = 8.82, = 0.003), the use of self-efficacy (Qb = 6.09, = 0.01), and the processes of change (Qb = 3.51, = 0.06).
CONCLUSION
TTM-based interventions significantly improved PA behavior, and their efficacy was not moderated by SOC but by the TTM theoretical constructs.
目的
本研究旨在探讨基于跨理论模型（TTM）的身体活动（PA）干预效果是否会根据以下标准而有所不同：（1）干预措施是否针对实际的行为改变阶段（SOCs）；（2）参与者是否根据其SOC进行选择；（3）其理论构成要素（决策平衡、诱惑、自我效能感、改变过程）。
方法
系统检索了33项评估基于TTM的干预措施促进成年人PA的随机对照试验。
结果
组间异质性统计量（Qb）显示，与未针对实际SOC的干预措施相比，针对实际SOC的干预措施在效果上没有差异（Qb = 1.48，P = 0.22）；与未根据SOC选择参与者的干预措施相比，根据SOC选择参与者的干预措施在效果上也没有差异（Qb = 0.01，P = 0.91）。基于TTM的干预措施无论是否针对实际SOC（科恩d值 = 0.36；95%置信区间（CI）：0.22 - 0.49），以及无论是否根据SOC选择参与者（d值 = 0.33；95%CI：0.13 - 0.53），均能增强PA行为（d值 = 0.23；95%CI：0.09 - 0.38）。基于TTM的干预措施效果的调节因素包括用于调整干预措施的理论构成要素数量（Qb = 8.82，P = 0.003）、自我效能感的使用（Qb = 6.09，P = 0.01）以及改变过程（Qb = 3.51，P = 0.06）。
结论
基于TTM的干预措施显著改善了PA行为，其效果不受SOC的调节，而是受TTM理论构成要素的调节。
