Understanding supplement use: an application of temporal self-regulation theory
MetadataShow full item record
© 2017 Informa UK Limited, trading as Taylor & Francis GroupVitamin and mineral supplement use is increasing worldwide. As evidence of the effects of these practices are equivocal at best, it is important to determine why individuals engage in vitamin and mineral supplement use through the application of a theoretical framework. The aim of this study was to employ temporal self-regulation theory (TST) to establish the determinants of supplement use. A cross-sectional design was used with a sample of 121 individuals who consume vitamins or minerals as dietary supplements. Hierarchical regression analyses were conducted to determine the influence of intention, habit, self-control, and the interaction between intention and habit and self-control on the frequency of supplement use. The model accounted for a significant proportion of variance in behaviour (R2 = .44) with intention and habit significantly related to supplement use. Self-control moderated the relationship between intention and behaviour indicating that intention was not related to behaviour when self-control was low. The TST model offers a satisfactory account of supplement use and provides avenues for interventions aimed at increasing safe and beneficial supplement use and decreasing potentially harmful supplement use.

(2013)According to the resource-depletion model, self-control is a limited resource that is depleted after a period of exertion. Evidence consistent with this model indicates that self-control relies on glucose metabolism and ...
