Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

• Change from pre-randomization Subjective Well-Being (Affect) at 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.

  Baseline, 1-week post-intervention, and 1-week follow-up

• Change from pre-randomization Subjective Well-Being (Life Satisfaction) at 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.

  Baseline, 1-week post-intervention, and 1-week follow-up

• Change from pre-randomization Subjective Well-Being (Eudaimonic Well-Being) at 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.

  Baseline, 1-week post-intervention, and 1-week follow-up

• Change from pre-randomization Subjective Well-Being at 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.

Secondary Outcomes (5)

• Change from pre-randomization self-reported Physical Activity at 1-week post-intervention and 1-week follow-up

• Change from pre-randomization self-reported Sedentary Behaviour at 1-week post-intervention and 1-week follow-up

• Change from pre-randomization Depression at 1-week post-intervention and 1-week follow-up

  Baseline, 1-week post-intervention, and 1-week follow-up

• Change from pre-randomization Anxiety (State) at 1-week post-intervention and 1-week follow-up

  Baseline, 1-week post-intervention, and 1-week follow-up

Intervention Group

EXPERIMENTAL

The intervention group will receive a pedometer and HAPA behavioural counseling with the aim of limiting their daily step count to \<5000 steps per day, over a one week period. Counseling strategies will be grounded in the HAPA model - specifically, creating an action plan and coping strategies for maximizing their daily sedentary behaviour and minimizing steps taken. Strategies may include: driving to locations more often, refraining from physical activity as much as possible, and/or completing tasks in sedentary postures.

Behavioral: HAPA behavioural counseling

Control Group

NO INTERVENTION

The control group will not receive any behavioural intervention or instruction.

Interventions

HAPA behavioural counseling BEHAVIORAL

Behavioural counseling grounded in the Health Action Process Approach (HAPA; i.e., action planning and coping planning) to maximize sedentary behaviour and minimize steps taken.
