Exploring the Effect of an Intervention on Women's Physical Activity Behaviour

- Brief Summary
Physical activity has been shown to reduce the risk of chronic diseases and promote physical and mental health and wellbeing, yet few women are active enough to see these benefits. Wearable activity trackers show promise for helping people increase their physical activity levels by supporting self-monitoring. However, few researchers have examined how providing people with these devices impacts physical activity levels, or motivation for physical activity which is a significant and robust predictor of physical activity. Based on previous research, it is possible that women's physical activity levels would be more likely to increase if they received an autonomy-supportive intervention to enhance motivation in addition to a wearable activity tracker. A pilot, three-armed randomized controlled trial was developed to test this hypothesis and to assess if changes in perceived autonomy-support, basic psychological need satisfaction/thwarting, motivational regulations, wellbeing indicators are associated with changes in physical activity over time.

- Primary Outcome Measures
Name Time Method Physical activity behaviour: Custom strength and resistance training questionnaire Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in strength and resistance training habits from baseline to post-intervention, and from post-intervention to follow-up.
Physical activity behaviour: International Physical Activity Questionnaire Short Form (IPAQ-S) Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in self-reported physical activity (over the past 7 days) from baseline to post-intervention, and from post-intervention to follow-up.
- Secondary Outcome Measures
Name Time Method Physical activity behaviour: Direct measure Duration of intervention phase (8 weeks). Change in weekly directly measured levels of physical activity as measured by accelerometers (Polar A300), which will be worn by participants assigned to Group 1 and Group 2 during waking hours for the duration of the intervention.
Perceived autonomy support: Perceived Autonomy Support Scale for Exercise Settings (PASSES; Hagger et al., 2007) Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in perceived autonomy support for physical activity from baseline to post-intervention, and from post-intervention to follow-up.
Basic psychological need thwarting: Psychological Need Thwarting Scale (PNTS; Bartholomew, Ntoumanis, Ryan, & Thøgersen-Ntoumani, 2011) Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in basic psychological need thwarting activity from baseline to post-intervention, and from post-intervention to follow-up.
Positive and Negative Affect Schedule (I-PANAS-SF; Thompson, 2016; Watson, Clark, & Tellegen, 1988). : Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in affect from baseline to post-intervention, and from post-intervention to follow-up.
Wearable activity tracker usage: Multiple choice questions Post-intervention (week 9). Frequency of wearable activity tracker usage in general during the intervention phase for participants randomized to Group 1 or Group 2.
Basic psychological need satisfaction: Psychological Need Satisfaction in Exercise Scale (PNSE; Wilson, Rogers, Rodgers, & Wild, 2006) Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in basic psychological need satisfaction for physical activity from baseline to post-intervention, and from post-intervention to follow-up.
Vitality: Subjective Vitality Scale (Ryan & Frederick, 1997). Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in vitality affect from baseline to post-intervention, and from post-intervention to follow-up.
Depression: Patient Health Questionnaire (PHQ-9; Kroenke, Spitzer, & Williams, 2001). Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in depressive symptoms from baseline to post-intervention, and from post-intervention to follow-up.
Retention rates Duration of recruitment and intervention phases (9 weeks). The number of participants completing all scheduled assessments.
Body composition Baseline (week 0) and post-intervention (week 9). Change in body composition from baseline to post-intervention as determined by a scale (Tanita BWB 800S) that uses bioelectrical impedance to assess body composition.
Waist circumference Baseline (week 0) and post-intervention (week 9). Change in waist circumference from baseline to post-intervention as measured using a measuring tape.
Motivational regulations: Behavioral Regulation in Exercise Questionnaire (BREQ-2R; Markland & Tobin, 2004; Wilson, Rodgers, Loitz, & Scime, 2006) Baseline (week 0), post-intervention (week 9), and follow-up (week 21). Change in motivational regulations for physical activity from baseline to post-intervention, and from post-intervention to follow-up.
Recruitment rates Duration of recruitment and intervention phases (9 weeks). The number of eligible participants who enrol in the study out of the number assessed for eligibility.
Acceptability: Open ended questions Duration of recruitment and intervention phases (9 weeks). For participants randomized to Group 1, what participants liked, disliked, and would change about the intervention.
Body mass Baseline (week 0) and post-intervention (week 9). Change in body mass measured from baseline to post-intervention as determined using a scale (Tanita BWB 800S).
