Overview
Brief Summary
Given the numerous physical and psychological benefits of engaging in regular physical activity (Biddle & Ekkekakis, 2005; Warburton et al., 2007) and the decrease in students' physical activity levels during the transition from high school to university (Bray & Born, 2010) it is important for researchers to develop time-and-cost-effective interventions to prevent this drop in physical activity. Intervention research shows mental contrasting (a goal setting strategy) can be taught in a cost-and-time-effective way in order to increase physical activity (Oettingen, 2012). Researchers have also found that individuals who consider the emotional effects of physical activity are more likely to be physically active than those who consider the health-related effects (Rhodes et al., 2009). The purpose of this research is to combine these two approaches to develop and evaluate a novel mental contrasting intervention to increase physical activity among a sample of undergraduate students.
Detailed Description
The transition from high school to university is a vulnerable period for discontinuing regular physical activity, which can have implications for individuals' physical and psychological health (Bray \& Born, 2010). Accordingly, it is imperative to find and implement cost and time-effective interventions to mitigate the consequences of this transition. Mental contrasting is a goal-setting strategy that involves imagining the greatest outcome associated with achievement of a desired future goal while considering the aspects of one's present situation that may serve as obstacles for attaining that same goal (Oettingen \& Gollwitzer, 2010). Intervention research has shown that mental contrasting can be taught as a metacognitive strategy in a cost- and time-effective way, affecting numerous health behaviours including physical activity (Oettingen, 2012). Drawing from diverse theoretical perspectives (e.g., Bechara, 2005; Lawton, Conner, \& McEachan, 2009; Williams, 2010), recent meta-analytic evidence suggests that affective judgements (e.g., enjoyable-unenjoyable) exert greater influence on physical activity behaviors than health-related instrumental judgements (e.g., useful-useless; Rhodes, Fiala, \& Conner, 2009). Nevertheless, research has yet to utilize mental contrasting as a means of targeting affective judgements, through intervention, in order to bolster physical activity promotion efforts. This research will examine how an affective mental contrasting intervention will change university students' affective judgements in comparison to instrumental mental contrasting and standard mental contrasting comparison conditions, and the subsequent impact of these changes on physical activity behaviour.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Individuals will be eligible to participate if they are female, inactive (i.e., engage in moderate-vigorous intensity physical activity for more than 30 minutes, less than three times a week), studying for an undergraduate degree at the University of British Columbia, and are able to read and converse in English.
Exclusion Criteria
- •Participants will be excluded if they have any self-reported physical health conditions using the online version of the PAR-Q+ (http://eparmedx.com/?page_id=75) that would restrict them from increasing their physical activity behaviours at the time of the intervention.
Outcomes
Primary Outcomes
Change is accelerometry measured moderate-vigorous physical activity from baseline
Time Frame: Four-week follow-up
Actigraph accelerometers will measure daily activities. A standard 7-day accelerometry monitoring protocol will be used. Participants will also complete three one-week physical activity logs corresponding to the three accelerometry periods. In these logs, participants will record the time the monitor is on and off, in addition to recording all activities performed with or without the monitor.
Secondary Outcomes
- Change in Godin's Leisure Time Exercise Questionnaire (GLTEQ)(Change between baseline and four-week follow-up)
- Change is Affective and Instrumental Physical Activity Judgements(Changes between baseline, the week immediately following the intervention, and a four-week follow-up.)
