简要总结
This study will explore the causality between outcomes of subjective well-being and sedentary behavior, through experimentally increasing the sedentary behavior levels of active university students. Half of the eligible participants will receive a behavioral counseling intervention to increase sedentary behavior over one week, while the other half will receive no instructions. After one week, all participants will receive no instructions and continue to wear the inclinometer for another week.
详细描述
The relationship between subjective well-being (SWB) and sedentary behavior (SB) has been briefly explored. However, the causality of the relationship (i.e., do higher levels of SB cause changes in SWB, or vice-versa) has not been fully examined. Experimentally increasing SB and observing the potential subsequent effect on SWB, in otherwise non-sedentary individuals, may help to determine the causation between SB and SWB.
An active sample of full-time university students attending Western University will be recruited. Upon obtaining consent, demographics will be taken. Baseline sedentary behavior levels will be confirmed objectively through inclinometer wear for 1-week. Upon confirmation of sufficient sedentary/non-sedentary time, participants will complete questionnaires assessing past-week: SWB, SB, physical activity, depression, and anxiety questionnaires. Participants will also be randomized to either a behavioral counseling intervention group, or a no-contact control group. Participants will then continue wearing the inclinometer for 1 week. After the intervention week, participants will complete the questionnaires again, after which all participants will be told to continue daily behavior, and wear the inclinometer for another week. Upon completion of this follow-up week, participants will complete questionnaires again.

结局指标
主要结局
Change from pre-randomization Subjective Well-Being (Affect) at 1-week post-intervention and 1-week follow-up
时间窗: Baseline, 1-week post-intervention, and 1-week follow-up
Subjective Well-Being (specifically, affect) will be assessed through the Positive Affect \& Negative Affect Scale (PANAS). The PANAS consists of a number of words that describe different feelings and emotions. Participants indicate the extent to which they feel a particular feeling and emotion over the past week, using a 5-point scale that ranges from 1 "very slightly or not at all" to 5 "extremely". An overall score for both positive and negative affect is calculated by summing up the points for those particular feelings/emotions (e.g., interested for positive affect, distressed for negative affect). Scores for positive affect can range from 10-50, with higher scores representing higher levels of positive affect. Scores for negative affect can range from 10-50, with lower scores representing lower levels of negative affect.
Change from pre-randomization Subjective Well-Being (Life Satisfaction) at 1-week post-intervention and 1-week follow-up
时间窗: Baseline, 1-week post-intervention, and 1-week follow-up
Subjective Well-Being (specifically, life satisfaction) will be assessed through the Satisfaction with Life Scale (SWLS); a 5-item scale designed to measure global cognitive judgments of one's life satisfaction. Participants indicate how much they agree or disagree with each of the 5-items over the past week, using a 7-point scale that ranges from 7 "strongly agree" to 1 "strongly disagree". An overall score (from 5 to 35) is calculated through summing the responses to the 5-items. Recommended cutoffs for interpretation are: 5-9, extremely dissatisfied; 10-14, dissatisfied; 15-19, slightly dissatisfied; 20, neutral; 21-25, slightly satisfied; 26-30, satisfied; 31-35, very satisfied.
Change from pre-randomization Subjective Well-Being (Eudaimonic Well-Being) at 1-week post-intervention and 1-week follow-up
时间窗: Baseline, 1-week post-intervention, and 1-week follow-up
Subjective Well-Being (Eudaimonic Well-Being) will be assessed through the Subjective Vitality Scale (SVS); a 6- or 7-item scale that assesses the state of feeling alive and alert - to having energy available to the self. For the purposes of this study, the 6-item individual difference level version of the SVS will be utilized. Participants indicate the degree in which a statement/item is true in general in their life, ranging from 1 "not at all" to 7 "very true". An overall score is obtained by averaging the scores for each of the 6-items, with higher scores indicating a greater feeling of vitality.
Change from pre-randomization Subjective Well-Being at 1-week post-intervention and 1-week follow-up
时间窗: Baseline, 1-week post-intervention, and 1-week follow-up
Subjective Well-Being will be assessed through the Warwick-Edinburgh Mental Well-Being Scale (WEMWBS). The WEMWBS consists of 14-items that assesses subjective well-being through both hedonic and eudaimonic dimensions of well-being. Participants select the option that best describes their experience with each of the 14-items over the last week (note: the original questionnaire assesses the last two weeks), using a 5-point scale that ranges from 1 "none of the time" to 5 "all of the time". A total score is calculated by summing the 14 individual statement scores. The minimum score is 14 and the maximum is 70, with higher scores indicating greater levels of subjective well-being.
