This study estimated the effect of extraversion, conscientiousness and variables from a modified two-component Theory of Planned Behaviour (TPB) on prospective self-reported physical activity (N = 397). Mediation analysis using structural equation modelling with bootstrapping suggested that only conscientiousness had significant effects on intention and behaviour. Affective attitude and perceived behavioural control partially mediated the effect on intention. The effect on behaviour was significantly mediated by TPB variables consistent with partial or total mediation. The modified TPB mediates the effects of conscientiousness on intention and behaviour; it is unclear whether it is sufficient to mediate all of the effect on behaviour.
本研究评估了外向性、尽责性以及修正后的计划行为理论（TPB）中的变量对前瞻性自我报告的身体活动的影响（N=397）。使用结构方程模型和自举法的中介分析表明，只有尽责性对意图和行为有显著影响。情感态度和感知行为控制部分中介了对意图的影响。TPB 变量对行为的影响显著，符合部分或完全中介。修正后的 TPB 中介了尽责性对意图和行为的影响；尚不清楚它是否足以中介对行为的所有影响。
