The physical activity training will involve a 6-week physical activity intervention consisting of weekly 1-hour sessions. Each session involves: (1) 30-minutes of behaviour change coaching (e.g., goal setting, action-planning, brainstorming strategies to overcome barriers to engaging in physical activity); and (2) 30-minutes of supervised and structured physical activity training. To address the aims of the study, participants will complete self-report questionnaires at baseline, post-intervention (following completion of the 6-week physical activity intervention), and 1-month following completion of the physical activity intervention. Questionnaires will assess demographic characteristics, primary outcomes (i.e., mental health symptomology including anxiety symptoms, depression symptoms, psychological distress), secondary outcomes (i.e., social support, social connectedness, physical activity behaviour) and contextual implementation factors (e.g., intervention reach, adherence, and program satisfaction) that may be linked to variation in primary and secondary outcomes while offering insight for wider dissemination. It is hypothesized that there will be no group differences between 1:1 delivery and group-based delivery on the primary outcomes. It is also hypothesized that group-based delivery, in comparison to 1:1 delivery will achieve greater improvements and more favourable maintenance effects in the secondary outcomes. Lastly, it is hypothesized that in comparison to the control group, 1:1 delivery and group-based delivery will be more effective in achieving change in the primary and secondary outcomes. conditions: Physical Activity conditions: Mental Health Issue studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL interventionModelDescription: A 3-arm parallel Randomized Controlled Trial (RCT) assessing the immediate (post-intervention) and short-term (1-month) impact of the experimental arms (1:1 physical activity delivery and group-based physical activity delivery) compared to a 10-week control arm (wait-list control) will be conducted. A parallel arm design will be implemented, whereby participants will be randomized to a study arm and each study arm will be allocated a different intervention. The protocol adheres to CONSORT guidelines and SPIRIT recommendations for reporting of clinical trial protocols. primaryPurpose: SUPPORTIVE_CARE masking: SINGLE maskingDescription: Following completion of the baseline assessment (T1), students will be randomly assigned to an experimental arm or the control arm by a program coordinator for the study. To prevent care provider bias, the physical activity coaches will remain blind to the purpose of group allocation and hypotheses of the study. Research Randomizer (www.randomizer.org) will be used to allocate participants into three equal groups using a blocked design (with an allocation ratio of 1:1:1). whoMasked: CARE_PROVIDER count: 93 type: ESTIMATED name: Physical Activity Intervention measure: Depression measure: Anxiety measure: Psychological distress measure: Social Support measure: Social Connectedness measure: Physical Activity Behaviour measure: Intervention Reach measure: Therapeutic Alliance measure: Intervention Satisfaction measure: Coach Perceptions sex: FEMALE stdAges: CHILD stdAges: ADULT stdAges: OLDER_ADULT facility: University of Toronto, Mental Health and Physical Activity Research Centre status: RECRUITING city: Toronto state: Ontario zip: M5S 2W6 country: Canada name: Melissa L deJonge, Msc role: CONTACT phone: 9059739414 email: melissa.dejonge@utoronto.ca name: Catherine M Sabiston, PhD role: CONTACT phone: 416-978-5837 email: catherine.sabiston@utoronto.ca name: Melissa L deJonge, Msc role: SUB_INVESTIGATOR name: Delaney E Thibodeau, Msc role: SUB_INVESTIGATOR name: Sandra Yeun, PhD role: SUB_INVESTIGATOR name: Luc Simard role: SUB_INVESTIGATOR name: Catherine M Sabiston, PhD role: PRINCIPAL_INVESTIGATOR lat: 43.70011 lon: -79.4163 hasResults: False
