Automatic processes moderate the association between reflective processes and movement behavior: A cross-sectional study

Dual-process theories postulate that both reflective and automatic processes regulate health behavior. Further research is required to test the basic postulates of dual-process theories. We investigated the direct associations and moderating effect between automatic processes and multiple indicators of reflective processes on various levels of physical activity and sedentary behavior assessed using accelerometry in adults who were not participating in regular physical exercise programs. This cross-sectional study included 257 adults. Each participant completed a computerized test for automatic associations, a set of questions assessing reflective processes, a seven-day assessment using accelerometers to determine their levels of physical activity and sedentary behavior. The results showed a direct relationship between perceived benefits (B = 15.90, p = 0.043), perceived cons (B =-12.81, p = 0.034), decisional intention (B =-0.07, p = 0.049) with light physical activity, and self-efficacy with daily steps (B = 485.71, p = 0.008). There was a positive association between intention strength and daily steps when implicit associations favored physical activity (b = 623.36, LLCI = 79.09, ULCI = 1167.62, p = 0.025); a negative association between self-efficacy and sedentary behavior when implicit asso-ciations favored sedentary behavior (b =-25.73, LLCI =-49.77, ULCI =-1.70, p = 0.035); and a positive association between intention strength and sedentary behavior when implicit associations favored physical ac-tivity (b = 34.18, LLCI = 8.81, ULCI = 59.56, p = 0.008). These findings underscore the importance of considering the interplay between reflective and automatic processes in shaping movement behavior.

Automated summary

This study investigated the influence of reflective and automatic processes on physical activity and sedentary behavior, and found direct associations and moderating effects between the two. The findings underline the importance of considering the interplay between reflective and automatic processes in shaping movement behavior.
