Trait self-control as a determinant of health behavior: Recent advances on mechanisms and future directions for research
Abstract
We summarize theory and research testing a mechanistic explanation for the trait self-control-health behavior relationship. Specifically, social cognition constructs summarizing individuals' utility, normative, risk, and capacity beliefs with respect to future health behavior performance are proposed to mediate the self-control-health behavior relationship. The effect represents the informational function of self-control in decision making. We also specify a mechanism wherein trait self-control moderates the intention-behavior relationship such that 'good' self-control affords effective intention-to-action translation. Both effects have pervasive support in the extent literature. We propose ongoing meta-analyses expected to provide further robust support for these mechanistic effects and the need for research employing designs enabling better directional and causal inferences in the effects, including experimental or types of cross-lagged panel design.
