BACKGROUND
Adults with physical disabilities experience lower physical activity (PA) engagement. The theory of planned behavior (TPB) has been one of dominant theories in understanding and promoting PA. There is no previous meta-analysis examining the use of the TPB on PA of adults with physical disabilities.
OBJECTIVE
The purposes of this review were 1) to conduct meta-analysis to examine predictive effects of TPB on PA behavior of adults with physical disabilities and 2) to investigate a possible moderator among components of TPB.
METHODS
One-stage meta-analytic structural equation modeling was used to conduct meta-analysis. Type of physical disability was examined as a moderator.
RESULTS
Intention had moderate effect on PA (β = 0.37, p < .001), attitude had a moderate effect on intention (β = 0.30, p < .001), SN had a non-significant effect on intention (β = 0.03, p = .75), and PBC had a moderate effect on intention (β = 0.43, p < .001) and a non-significant direct effect on PA (β = 0.09, p = .18). The studies conducted with only participants with SCI lowered the predictive effect (β = -0.12, p = .02) of PBC on PA.
CONCLUSIONS
Predictive effects of component of TPB were slightly different from those of individuals without disabilities. Type of physical disability can be a critical factor determining the impact of perceived control on PA behavior. Attitude and PBC can be targets for promoting PA of adults with physical disabilities.
背景
身体残疾的成年人参与身体活动（PA）的程度较低。计划行为理论（TPB）是理解和促进 PA 的主要理论之一。以前没有关于 TPB 在身体残疾成年人 PA 中的应用的元分析。
目的
本次综述的目的是 1）进行元分析，以检验 TPB 对身体残疾成年人 PA 行为的预测效果，2）探讨 TPB 各成分中的一个可能的调节因素。
方法
采用单阶段元分析结构方程模型进行元分析。身体残疾的类型被视为一个调节因素。
结果
意图对 PA 有中等程度的影响（β=0.37，p<0.001），态度对意图有中等程度的影响（β=0.30，p<0.001），主观规范对意图没有显著影响（β=0.03，p=0.75），而感知行为控制对意图有中等程度的影响（β=0.43，p<0.001），对 PA 没有显著的直接影响（β=0.09，p=0.18）。仅对 SCI 参与者进行的研究降低了感知行为控制对 PA 的预测效应（β=-0.12，p=0.02）。
结论
TPB 各成分的预测效果与无残疾个体略有不同。身体残疾的类型可能是决定感知控制对 PA 行为影响的关键因素。态度和感知行为控制可以成为促进身体残疾成年人 PA 的目标。
