Secondary Research Questions
Does the planning condition improve motivational, health-related quality of life, and health-related fitness outcomes compared to the control condition at six months?
Hypothesis: The planning condition will not affect intentions or underlying motives (theory of planned behaviour constructs) for physical activity because its effect on behavior is to tie initial intentions better to behavioural action (i.e., behavioural regulation) and not to enhance motivation. Health-related fitness and quality of life, however, will be higher for the planning condition in comparison to the standard physical activity education intervention condition. The effect may wane over time from the initial measurement period but all outcomes will remain significantly higher at six months in the planning condition compared to the standard physical activity education group.
Can motivational variables predict adherence? Do these differ by condition?
Hypothesis: The approach will test Ajzen's theory of planned behavior, extended by the concept of active planning. Affective attitude and perceived behavioural control will predict intention, intention will predict planning and planning will predict adherence across conditions.
Background:
Obesity is rapidly becoming one of the more serious public health challenges of this century, especially when considering that overweight and obese children are likely to stay obese into adulthood and are at a higher risk of developing chronic diseases at a younger age. The need for changes to modifiable risk factors associated with obesity and chronic diseases is paramount. Physical activity is associated with the reduction of several chronic diseases in adults, including breast cancer, colorectal cancer, CVD, stroke, high blood pressure, type 2 diabetes, osteoporosis, and hypertension. In children 5 to 17 years old, physical activity and high physical fitness help guard against high blood pressure, high blood cholesterol, metabolic syndrome, low bone density, depression, injuries, and obesity. Unfortunately in Canada, well over half the adult population, and almost half the child population, are not active enough to reap these health benefits. Children spend considerable time within the care of their parents, and indeed parents appear to be the 'gatekeepers' of children and their experiences during family time. Our review of 34 intergenerational studies showed that parental support was synonymous with physical activity in their children. Thus, focusing on the parent as a means to changing youth physical activity appears a necessity. At present, physical activity interventions focused on the family are limited and have resulted in negligible changes. A recent review of these studies demonstrated very low success in producing behavior change - considerably lower than the comparable adult literature. The authors suggest that focused research attention needs to be placed on the family in order to improve our current practice of physical activity promotion. Our pilot study [15], which serves as the template for this research proposal, demonstrated that focused planning on when, what, how, where, and overcoming other expected barriers followed by prompts and cues resulted in a significant change in physical activity over the more standard persuasion/education approach. The following proposal is an extension of this line of successful research with improvements to the methodological rigor and sample generalizability used in the pilot study.
Target population:
The targeted population will be inactive families within the Greater Victoria Area, British Columbia.
Sample size:
A total of 160 families will be recruited (n=80 per group).
Intervention:
The intervention will follow the prior work conducted in our successful pilot trial. The standard (comparison group) package will consist of Canada's family guide to physical activity guidelines recommending 60 minutes of activity a day in bouts as short as five to ten minutes for children and a breakdown of ways for the family to achieve this physical activity (structured, unstructured, endurance, strength, activities, less than 60 minutes of sustained sedentary activity, reduce screen viewing by 30 min per day) commensurate with this guide. This will include the new insert by CSEP. The guide also contains arguments and information about the benefits of physical activity.
The intervention condition will receive the same guidelines as the comparison condition but will also be provided with family physical activity planning material. This material will include skill training content (workbook how to plan for family physical activity) and practical material to create a plan (i.e., a colourful dry erase wall calendar for family activities with fridge magnets). The skill training material for planning is based on several streams of prior work in the adult physical activity literature. Families were instructed to plan for "when," "where," "how," and "what" physical activity will be performed commensurate with the creation of implementation intentions/action planning. The workbook, however, also focuses on problem solving barriers to physical activity which is more akin to coping planning and traditional goal setting. The design of all material was created for the pilot study and features graphic design and colour images that represent family physical activity.

Change from baseline in children's physical activity to 6 months
Children's physical activity will be quantified by accelerometry. Children will wear an accelerometer for a minimum of 10 hours per day for 7 days at baseline and 6 months. Additionally this measure will assess intermediate outcomes at 6 weeks and 3 months.
Time frame: baseline & 6 months
Change from baseline in parent's physical activity at 6 months
Parent's physical activity will be quantified by accelerometry. Parents will wear an accelerometer for 7 days at baseline, 6 weeks, 3 and 6 months, for a minimum of 10 hours per day.
Time frame: baseline & 6 months
Change from baseline in motivation at 6 weeks
Motivations for family based physical activity and personal physical activity will be measured using the constructs of the TPB and SDT including affective attitude, instrumental attitude, injunctive norm, descriptive norm, perceived control, behavioural, normative, control beliefs, intrinsic motivation, extrinsic motivation, and amotivation. The Behavioural Regulations in Exercise Questionnaire-2 (BREQ-2) will be completed by both parents and the target child. Change in motivation variables will be examined (6 weeks minus baseline).
Time frame: baseline & 6 weeks
Change from baseline in self-reported family based physical activity and personal physical activity at 6 weeks
The target child will complete a modified version of the Physical Activity Questionnaire for Children (PAQ-C) to assess habitual moderate to vigorous physical activity. The Godin Leisure-Time Exercise Questionnaire (LSI) will be used to measure self-reported physical activity in parents. The LSI contains three questions, which assess the frequency of mild, moderate, and strenuous activity performed for at least 15 minutes during free time in a typical week. Change in self-reported physical activity will be examined (6 weeks minus baseline).
Time frame: baseline & 6 weeks
Change from baseline in health-related quality of life / psychosocial distress at 6 months
Quality of life will be assessed with parents using the Satisfaction with Life Scale and the 12 item Short Form Health Survey. The target child's quality of life will be assessed using the 5-item Satisfaction with Life Scale Adapted for Children (SWLS-C). Change in health-related quality of life/ psychosocial distress from baseline to 6 months (i.e., post-intervention) will be examined.
Time frame: baseline & 6 months
Change from baseline in physical home environment at 6 months
The physical home environment will be assessed using three sections from the Active Where surveys (i.e., Section A. equipment checklist, Section P. Home Environment, \& Section R. Sedentary Behavior). The Active Where surveys include items designed to to assess how the physical environment impacts the physical activity and eating behaviors of youth. Change in physical environment will be examined from baseline to 6 months (post-intervention).
Time frame: baseline and 6 months
Change from baseline in body composition at 6 months.
Skinfolds (triceps, biceps, subscapular, supra iliac, medial calf) will be measured using standard anthropometric procedures. Change in body mass index (BMI), waist circumference, and sum of 5 sites will be examined from baseline to 6 months (post-intervention)
Time frame: baseline and 6 months
Change from baseline in cardiovascular fitness at 6 months
A single state treadmill walking test will be used to assess cardiovascular fitness in both parents and target child.
