Sitting through life? Psychosocial Antecedents of Sedentary Behaviour in a Post-Secondary Setting
Currently, there is a paucity of research on the psychosocial antecedents of sedentary behaviour (SB) in a post-secondary setting. Theory of Planned Behaviour (TPB) constructs may influence sedentary behaviour amongst students. Further, normative messages may be one tool for altering perceptions of sedentary behaviour. However, the effect of descriptive norm messages on sedentary behaviour is currently unknown. The primary purpose of this study is to examine students’ perceptions of sedentary behaviour; the secondary purpose is to investigate whether the receipt of a normative message is an efficacious tool for reducing students’ sedentary behaviour. Post-secondary students will complete an online questionnaire and will randomly receive an injunctive norm, descriptive norm, or control sedentary behaviour message. The questionnaire will measure demographics, TPB constructs, and self-reported SB. One week later, they will complete the same questionnaire. Multiple regression and ANOVAs will be used to address the two study purposes, respectively. Results may inform future interventions aimed at decreasing students’ sedentary behaviour levels.
