Vasiljevic, M., Ng, Y., Griffin, S., Sutton, S., & Marteau, T. (2015). Is the intention-behavior gap greater among the more deprived? A meta-analysis of five studies on physical activity, diet and medication adherence in smoking cessation. British Journal of Health Psychology, 21 11-30. https://doi.org/10.1111/bjhp.12152
Objectives: Unhealthy behavior is more common amongst the deprived thereby contributing to health inequalities. The evidence that the gap between intention and behavior is greater among the more deprived is limited and inconsistent. We tested this hypothesis using objective and self-report measures of three behaviors, both individual- and area-level indices of socio-economic status (SES), and pooling data from five studies. Design: Secondary data analysis. Methods: Multiple linear regressions and meta-analyses of data on physical activity, diet, and medication adherence in smoking cessation from 2511 participants. Results: Across five studies we found no evidence for an interaction between deprivation and intention in predicting objective or self-report measures of behavior. Using objectively measured behavior and area-level deprivation, meta-analyses suggested that the gap between self-efficacy and behavior was greater among the more deprived (B = 0.17 [95% CI = 0.02, 0.31]). Conclusions: We find no compelling evidence to support the hypothesis that the intention-behavior gap is greater among the more deprived.
