“…Despite a strong theoretical case for peer-delivered interventions, only half of the reviewed studies employed a guiding theoretical framework; without a guiding theory, researchers often overlook the study of potential mechanisms that could account for an intervention's effects [54]. Indeed, virtually all of the reviewed studies engaged peers in activities that might be expected to influence key motivational determinants, but only three studies included measures of such variables, and none of them tested for mediating effects.…”

The purpose of this systematic review was to catalogue and synthesize published studies that have examined the effects of peer-delivered physical activity interventions on physical activity behavior. Ten published studies were identified that met the inclusion criteria. The following information was extracted from each study: study design and duration; characteristics of the sample, peers, and interventions; and physical activity outcomes. In all articles reporting within-groups analyses, peer-delivered interventions led to increases in physical activity behavior. When compared to alternatives, peer-delivered interventions were just as effective as professionally delivered interventions and more effective than control conditions for increasing physical activity. Only three studies included measures of social cognitive variables, yielding some evidence that peers may enhance self-efficacy and self-determined forms of motivation. Based on these findings, interventionists are encouraged to include peer mentors in their intervention delivery models. Investigators are encouraged to pursue a more comprehensive understanding of factors that can explain and maximize the impact of peer-delivered activity interventions.

These benefits have also been reported in subpopulations such as older adults [8] and persons with disabilities [9]. Unfortunately, most adults do not perform PA at the recommended level to experience such health benefits [10,11]. Indeed, 39 % of adults are completely sedentary [11], and the rate of inactivity increases with age [8,12] and physical impairment (e.g., [13]).Although health care professionals often hold a role of trusted counselor or health mentor for their

“…Attention to theory-based interventions and intervention mapping were important efforts to ground intervention design in what is known about behavioral sciences. The focus on theory in intervention development was associated with calls to understand causal mechanisms of change or "how" interventions had their effects, with more thoughtful process evaluation, planned mediational analysis [29] and coding scheme development to delineate the extent to which interventions are based on theory [30][31][32][33].…”

Deconstructing interventions into the specific techniques that are used to change behavior represents a new frontier in behavioral intervention research. This paper considers opportunities and challenges in employing the Behavior Change Techniques Taxonomy (BCTTv1) developed by Michie and colleagues, to code the behavior change techniques (BCTs) across multiple interventions addressing obesity and capture dose received at the technique level. Numerous advantages were recognized for using a shared framework for intervention description. Coding interventions at levels of the social ecological framework beyond the individual level, separate coding for behavior change initiation vs. maintenance, fidelity of BCT delivery, accounting for BCTs mode of delivery, and tailoring BCTs, present both challenges and opportunities. Deconstructing interventions and identifying the dose required to positively impact health-related outcomes could enable important gains in intervention science.

Does Neighbourhood Walkability Moderate the Effects of Mass Media Communication Strategies to Promote Regular Physical Activity?

et al. 2013

Background Mass media campaigns are widely used in Australia and elsewhere to promote physical activity among adults. Neighbourhood walkability is consistently shown to be associated with walking and total activity. Campaigns may have different effects on individuals living in high and low walkable neighbourhoods. Purpose The purpose of this study is to compare pre-and post-campaign cognitive and behavioural impacts of the Heart Foundation's Find Thirty every day® campaign, in respondents living in high and lower walkable neighbourhoods. Methods Pre-and post-campaign cross-sectional survey data were linked with objectively measured neighbourhood walkability. Cognitive and behavioural impacts were assessed using logistic regression stratified by walkability.Results Cognitive impacts were significantly higher postcampaign and consistently higher in respondents in high compared with lower walkable neighbourhoods. Post campaign sufficient activity was significantly higher and transport walking significantly lower, but only in residents of lower walkable areas. Conclusions Cognitive impacts of mass media physical activity campaigns may be enhanced by living in a more walkable neighbourhood.
