The purpose of this study was to examine the associations of an online coaching intervention that included goal setting with movement behaviors and perceived general health (GH) and emotional wellbeing (EW) in college students. Participants were college students from a university within the western United States (=257; 57.2% female). Participants met with health coaches in an online setting for one hour and goals were set for physical activity (PA) and/or sleep duration. PA, sleep duration, and perceptions of GH and EW were collected at baseline and at 2- and 4-weeks after the coaching session within a single arm research design. Mediation analyses determined the indirect effect (IE) of each movement behavior both after the health coaching session and after goal setting on the GH and EW outcomes in addition to the bidirectional association between GH and EW. No movement behavior positively mediated the associations with GH or EW after the health coaching session or after goal setting, although after goal setting PA and weeknight sleep at 2-weeks associated with GH at 4-weeks (β=0.16-0.39, <0.01) and associated with EW at 4-weeks (β=0.22-0.25, <0.01). EW mediated the associations of the health coaching session on GH (IE=0.19, <0.001) and GH mediated the association of the health coaching session on emotional wellbeing (IE=0.09, <0.001). In conclusion, movement behaviors correlated with GH and EW, but no positive mediating associations were observed. After the health coaching session, EW mediated the association with GH and vice-versa, suggesting a bidirectional association between the two health perceptions.
本研究的目的是探讨一种包括目标设定在内的在线指导干预措施与大学生运动行为、感知总体健康（GH）和情绪健康（EW）之间的关联。参与者是来自美国西部一所大学的大学生（n = 257；57.2%为女性）。参与者在在线环境中与健康教练会面一小时，并为身体活动（PA）和/或睡眠时间设定目标。在单组研究设计中，在基线以及指导课程后的第2周和第4周收集PA、睡眠时间以及对GH和EW的感知。中介分析确定了健康指导课程后以及目标设定后每种运动行为对GH和EW结果的间接效应（IE），以及GH和EW之间的双向关联。在健康指导课程后或目标设定后，没有运动行为对与GH或EW的关联起到正向中介作用，不过在目标设定后，第2周的PA和工作日睡眠时间与第4周的GH相关（β = 0.16 - 0.39，p < 0.01），并与第4周的EW相关（β = 0.22 - 0.25，p < 0.01）。EW介导了健康指导课程与GH的关联（IE = 0.19，p < 0.001），GH介导了健康指导课程与情绪健康的关联（IE = 0.09，p < 0.001）。总之，运动行为与GH和EW相关，但未观察到正向中介关联。在健康指导课程后，EW介导了与GH的关联，反之亦然，这表明这两种健康感知之间存在双向关联。
