Behavioral and Social Approaches to Increase Physical Activity: Family-Based Social Support
Family-based interventions attempt to change health behavior through the use of techniques that increase the support of family members for behavior change. Programs typically include joint or separate educational sessions on health, goal-setting, problem-solving, or family behavioral management and often incorporate some physical activities.
Summary of Task Force Recommendations & Findings
The Community Preventive Services Task Force finds insufficient evidence to determine the effectiveness of family-based social support interventions in increasing levels of physical activity or improving fitness because of inconsistent results.
About the Interventions
These interventions target factors in the social environment and interpersonal and behavioral patterns that are likely to influence physical activity behaviors.
Interventions in this category targeted to children and their families are often implemented as part of a larger strategy that includes other school-based interventions, such as school-based physical education or classroom-based health education.
Results from the Systematic Reviews
Eleven studies qualified for the review.
- As a group, these studies found inconsistent results, with some studies showing increases in activity and others showing decreases.
- This inconsistency of results across the body of evidence evidence also was seen in the physiologic measures assessed.
These results were based on a systematic review of all available studies, conducted on behalf of the Task Force by a team of specialists in systematic review methods, and in research, practice, and policy related to physical activity.
An economic review of this intervention was not conducted because the Task Force found insufficient evidence to determine its effectiveness.
