体育活动中意图-行为差距的自我调节调节者：年轻人的生态瞬时评估研究

Physical activity (PA) intentions do not always translate into behavior, particularly at the momentary level, producing a well-documented intention–behavior gap; yet it remains unclear whether self-regulatory factors explain for whom and when intention–PA coupling is stronger or weaker. This study examined whether time-invariant self-regulatory traits (behavioral inhibition system/behavioral activation system sensitivity, trait self-control, and PA self-regulatory strategies) and time-varying momentary states (feeling focused, feeling in control, procrastinating) moderate the within-day associ
