ABSTRACT
Early career professionals (ECPs) are a critical target for physical activity (PA) promotion. Affect contributes to an established PA intention-behaviour gap and is pertinent among ECPs. OBJECTIVE: The purpose of this study was to examine the feasibility and acceptability of a web-based intervention and explore the effects on secondary outcomes (moderate-to-vigorous PA (MVPA), emotion regulation, multi-process action control constructs). METHODS: Adults aged 25-44 who were employed at least part-time in a desk-based job and not meeting PA guidelines (<150 min MVPA) were recruited and randomized into a 6-week online intervention integrating acceptance and commitment principles and affect regulation strategies, or a control group. RESULTS: Forty adults were recruited and randomized to the web-based intervention (n = 21) and waitlist control (n = 19). The recruitment rate was 29%, retention was 75%, engagement was 68%, and satisfaction was high in both quantitative and qualitative assessment. Participants allocated to the intervention improved MVPA (ηp2=0.30), emotion regulation (ηp2 =0.49), behavioural regulation (ηp2=0.53), affective attitude (ηp2=0.23), identity (ηp2=0.24), and constructs of mindfulness (ηp2=0.44), and valued living (ηp2=0.20). CONCLUSIONS: Primary outcomes concerning feasibility were adequate and secondary outcomes improved, suggesting a full-scale randomized controlled trial is feasible with minor modifications. A large-scale study is warranted to establish intervention effectiveness.
ABSTRACT
BACKGROUND: Regular physical activity (PA) is associated with many health benefits during childhood, and tracks into desirable PA patterns and health profiles in adulthood. Interventions designed to support these behaviours among young children are critical. Family-based interventions focusing on parent-child activities together (i.e., co-activity) among preschool-aged children are warranted. Targeting parental support practices can increase the frequency of co-activity, however interventions must move beyond merely building intention and planning skills for successful maintenance. Interventions designed to increase co-activity habit strength may facilitate the sustainability and thus impact child PA. The purpose of this study is to compare the effects of three intervention conditions designed to increase child PA through co-activity: a standard education condition (information about benefits), a planning (action planning, coping planning) + education condition and a habit (context-dependent repetition from prompts and cues) + planning +education condition. METHODS/DESIGN: A longitudinal three-arm parallel design randomized trial will compare three conditions over six months. Families are eligible if they have at least one child between 3y and 5y that is not meeting 60mins/day of moderate to vigorous physical activity (MVPA). The primary outcome (child MVPA) is assessed via accelerometry at baseline, six weeks, three months and six months (primary endpoint). Intervention materials targeting co-activity are delivered post baseline assessment, with booster sessions at six weeks and three months. Parental co-activity habit, parent-child co-activity and other behavioural constructs are also assessed via questionnaire at all measurement occasions. As tertiary outcomes, parental PA is measured via accelerometry and co-activity is measured via a Bluetooth-enabled proximity feature. A total of 106 families have been recruited thus far from the Greater Victoria region. The study is ongoing with a minimum target of 150 families and an anticipated recruitment completion date of August 2022. DISCUSSION: This protocol describes the implementation of a randomized trial evaluating the effectiveness of a habit formation group compared with a planning group and an education only group to increase child PA through targeting parent-child co-activity. This information could prove useful in informing public health initiatives to promote PA among families with preschool-aged children. TRIAL REGISTRATION: This trial was prospectively registered on clinicaltrials.gov in February 2016, identifier NCT03055871 .

BACKGROUND: Adult participation in sport is associated with important positive psychosocial outcomes. Despite the multitude of benefits that have been linked to sport participation, adult participation rates in Canada remain low. Parents with young children represent a demographic that may benefit considerably from sport participation, given the prevalence of inactivity coupled with increased levels of psychosocial distress among this group. This study aims to evaluate the efficacy of two types of sport participation (individual sport and team sport) on key psychosocial outcomes compared with a "personal time" control condition among parents with young children. METHODS/DESIGN: The three-arm, parallel design, single-blind, randomized controlled trial will compare a team sport condition, an individual sport condition, and a "personal time" control condition over 3 months. Parents are eligible if they have a child under 13 years of age, are not participating in a sport at baseline, and are not meeting Canadian Physical Activity Guidelines. Psychosocial variables (quality of life, relationship satisfaction, social functioning, parental stress, and enjoyment) will be assessed at baseline, 6 weeks, and 3 months. A total of 161 parents have been recruited thus far from the Greater Victoria region in British Columbia, Canada. The study is ongoing with a target goal of 240 participants and an anticipated completion date of December 2021. DISCUSSION: This protocol describes the implementation of a randomized controlled trial that evaluates the effectiveness of sport participation for increasing positive psychosocial outcomes. This information could prove useful for future adult sport participation and potentially inform public health initiatives involving parents and families.
