Self-efficacy Moderates the Mediation of Intentions Into Behavior via Plans

Abstract

Objective: To examine the putative moderating role of self-efficacy in the intention-planningbehavior relationship. Methods: In N=812 individuals, intentions (independent variable) were assessed at baseline, whereas action plans (mediator), self-efficacy (moderator), and physical activity (dependent variable) were measured again 4 weeks later. We examined a moderated-mediation model. Results: Self-efficacy moderates the mediation process: the strength of the mediated effect increased along with levels of selfefficacy. The results remain valid after accounting for baseline physical activity. Conclusions: For plans to mediate the intentionbehavior relation, people must hold sufficiently high levels of self-efficacy. If they lack selfefficacy, planning may be in vain.

Metformin and placebo therapy both improve weight management and fasting insulin in obese insulin-resistant adolescents: a prospective, placebo-controlled, randomized study

“…This placebo effect shows how important the belief in therapy effects and selfefficacy may be (31), as it strengthens the motivation for lifestyle changes in obese adolescents and enhances adhesion to a healthy lifestyle.…”

Optimising the delivery of food allergy information. An assessment of food allergic consumer preferences for different information delivery formats

“…It is relevant to distinguish the concept of ''confidence'', as used in the research presented here, from that of ''self-efficacy''. The latter to an individuals perceived ability to act in such a way as to affect their life (for example, see, inter alia, Bandura, 1977;Lippke, Wiedemann, Ziegelmann, Reuter, & Schwarzer, 2009). This differs from the concept of ''confidence'' as used in the present study, which refers to the extent to which an individuals consumer trusts the safety of food products, (De Jonge, Van Trijp, van der Lans, Renes, & Frewer, 2008), in particular if credence factors (i.e., consumer perceptions of product qualities which are not directly verifiable, but are indicated by information or claims) are utilised in decision-making regarding consumption.…”

Social-cognitive predictors of physical activity initiation in type 2 diabetes following diabetes self-management education : application of the health action process approach.

“…Within the physical activity literature, the HAP A has been applied to a handful of studies across healthy populations (Schwarzer et aI., 2007) and chronic illness populations, including orthopedic rehabilitation, cardiac rehabilitation, and pre-diabetes (Absetz et aI., 2007;Laatikainen et aI., 2007;Lippke, Wiedemann, Ziegelmann, Reuter, & Schwarzer, 2009;Reuter et aI., 2009;Scholz et aI., 2005;Scholz, Schuz, Ziegelmann, Lippke, & Schwarzer, 2008;Schwarzer, Luszczynska, Ziegelmann, Scholz, & Lippke, 2008;Sniehotta, Schwarzer, Scholz, & Schuz, 2005;Sniehotta, Scholz, et aI., 2005;Sniehotta, Scholz, & Schwarzer, 2006;Uutela et aI., 2004;Wiedemann, Schuz, Sniehotta, Scholz, & Schwarzer, 2009;. Most of the identified studies are based on analyses from chronic illness samples derived from Berlin, Germany, limiting the generalizability of findings and highlighting the need to examine the usefulness of the HAP A's framework in more diverse settings and samples.…”
