A Scoping Review of Behavior Change Techniques Used to Promote Physical Activity among Women in Midlife
Women in midlife experience health risks that could be mitigated by regular physical activity (PA), but rarely achieve PA levels that can protect their health. As a result, many behavioral interventions are designed to promote PA in this population, though their efficacy and effectiveness appear to be limited. It is not clear which theoretical models or associated behavior change techniques (BCTs) are used in PA interventions designed for women in midlife, and little is known about how BCTs are activated in such interventions. A synthesis of this information would be useful as an initial step toward improving PA interventions for this at-risk group, and thus, represented the goal of the present scoping review. Of the 4,410 initial results, 51 articles met inclusion criteria, and these described 36 unique interventions. More than half of the articles (59%) named an underlying theoretical model and interventions included an average of 3.76 identifiable BCTs (range 1-11). However, descriptions of many interventions were limited and did not provide enough detail to determine whether or how specific BCTs were activated. The present review identifies important limitations of existing literature and key opportunities for advancing the design of PA interventions for women in midlife.
