Abstract

Prior research identified assorted relations between trait and social cognition models of personality and engagement in physical activity. Using a representative U.S. sample (N = 957), the goal of the present study was to test two alternative structural models of the relationships among the extraversion-related facet of activity, the conscientiousness-related facet of industriousness, social cognitions from the Theory of Planned Behavior (perceived behavioral control, affective attitudes, subjective norms, intentions), Social Cognitive Theory (self-efficacy, outcome expectancies), and the Transtheoretical Model (behavioral processes of change), and engagement in physical activity. Path analyses with bootstrapping procedures were used to model direct and indirect effects of trait and social cognition constructs on physical activity through two distinct frameworks – the Theory of Planned Behavior and Neo-Socioanalytic Theory. While both models showed good internal fit, comparative model information criteria showed the Theory-of-Planned-Behavior-informed model provided a better fit. In the model, social cognitions fully mediated the relationships from the activity facet and industriousness to intentions for and engagement in physical activity, such that the relationships were primarily maintained by positive affective evaluations, positive expected outcomes, and confidence in overcoming barriers related to physical activity engagement. The resultant model – termed the Disposition-Belief-Motivation model– is proposed as a useful framework for organizing and integrating personality trait facets and social cognitions from various theoretical perspectives to investigate the expression of health-related behaviors, such as physical activity. Moreover, the results are discussed in terms of extending the application of the Disposition-Belief-Motivation model to longitudinal and intervention designs for physical activity engagement.

Highlights

Accumulated research findings demonstrate the importance of social cognitions – beliefs, attitudes, and values anchored in the context of exercise – as correlates and predictors of physical activity intentions and behavior (e.g., Hausenblas et al, 1997; Courneya et al, 2006; Scholz et al, 2009; Rhodes et al, 2010; Lee, 2011; Poomsrikaew et al, 2012; White et al, 2012)
All other correlations were significant at p < 0.01
Both models had a comparative fit index (CFI) score of at least 0.99, indicating that at least 99% of the covariation in the data was reproduced by each model

Summary

Introduction

Accumulated research findings demonstrate the importance of social cognitions – beliefs, attitudes, and values anchored in the context of exercise – as correlates and predictors of physical activity intentions and behavior (e.g., Hausenblas et al, 1997; Courneya et al, 2006; Scholz et al, 2009; Rhodes et al, 2010; Lee, 2011; Poomsrikaew et al, 2012; White et al, 2012). Research has incorporated personality traits, especially from the Big Five domains of extraversion and conscientiousness, into social cognition models to account for the effects of these relatively stable trans-situational dispositional tendencies on physical activity intentions and physical activity behavior (e.g., Rhodes et al, 2002, 2004b; Rhodes and Courneya, 2003; Bogg, 2008; Hoyt et al, 2009). None of this work has bridged across these three major social cognition frameworks to investigate the structure of the multifarious components of these models, let alone incorporate key physical activity-related personality trait facets into such an integration, such as trait activity (a facet of extraversion) and industriousness (a facet of conscientiousness). Using two distinct theoretical perspectives – the Theory of Planned Behavior and NeoSocioanalytic Theory – the primary aim of the present work is to test two structural models of constructs from these varied levels of analysis and conceptual origins using a representative U.S sample
