Increasing Physical Activity Among Early Career Professionals: A Feasibility Trial of an Online Intervention

Health Promotion, Physical Activity

Emotion Regulation, Intention-behaviour Gap, Early Career Professionals

Physical activity promotion remains a public health priority and accessible and scalable interventions are needed. Early career professionals are at-risk for inactivity and therefore a critical target for physical activity promotion. An online delivery format made up of web-based lessons and podcasts meets accessibility needs for this time-pressed population and has strong potential for reach. This study explores the feasibility of a theory-based intervention which accounts for action control, namely by leveraging the the Multi-Process Action Control framework (M-PAC) and targeting factors such as incidental affect (e.g., work-related stress) through emotion regulation strategies grounded in the principles of Acceptance and Commitment Therapy. The primary objective of this study is to examine the feasibility and acceptability of a 6-week web-based physical activity behaviour change program for early career professionals. Primary outcomes include rates of recruitment, attention, adherence as well as study satisfaction and intervention acceptability. Secondary measures will include physical activity and emotion regulation. Additional measures will explore Multi-Process Action Control constructs, perceived stress, applied mindfulness, action and acceptance, and valued living.

BACKGROUND Despite the well-established physical and psychological benefit of physical activity, much of the population is not meeting recommended guidelines. Critical life transitions have been linked to physical activity decline and it follows that targeting those in transition is prudent. Early career professionals are one such critical demographic. Given the stress, demands, and time constraints that come with shifting to the workforce, it can be difficult to follow through on physical activity intentions. As such, an intervention designed to incorporate intention translation, mitigate incidental affect, and foster emotion regulation is warranted. This study will examine the feasibility of an accessible online intervention. Qualitative analysis will assist with refining the intervention and the protocol. Progression criteria will be used to determine whether revisions should be considered before proceeding to a definitive randomized controlled trial. TARGET POPULATION Early career professionals, operationalized as adults aged 25-44 and working at a desk-based job. DESIGN An open parallel feasibility randomized controlled trial will compare an online intervention condition to a waitlist control condition. This study features a controlled baseline with a post-intervention (6 weeks) evaluative design with an embedded qualitative and quantitative process evaluation. INTERVENTION Participants will be randomized to 1) a waitlist control group and 2) and Online Platform Intervention group. Condition one: Waitlist control group representing the comparator. The control group will complete the baseline and final questionnaires. Following study completion, this group has the option of gaining access to the online platform for their own benefit. Condition two: Intervention group. Those in the intervention condition will gain access to the online platform after completing a baseline questionnaire. Participants will engage in a self-guided 6 week program made up of weekly lessons. A 'booster session' will be offered at 3 weeks to check in regarding progress and engagement. A follow-up survey will be completed at 6 weeks, post-intervention. Participants will be invited to complete a qualitative semi-structured exit interview following final questionnaire completion.
