Clarifying the importance and moderating roles of temporal self-regulation theory across behaviour types.

Objectives: The aim of this study was to explore the utility of temporal self-regulation theory across four behaviours differing in complexity and approach or avoidance nature. Specifically, we explored if intention, habit, cues, self-regulation (disorganisation, coping planning, task switching, present orientation, sensation seeking, automaticity, planning and distractibility) and interactions between constructs could account for variance in fruit consumption, unhealthy snacking, walking and recycling.

Methods and measures: Two hundred and fifty-four participants completed a two-part online survey measuring theory constructs at time one and behaviours at time two. Data was analysed using hierarchical multiple regression and binary logistic regression analyses.

Results: Findings partially support the theory with differential importance of constructs across behaviours. Intention, habit, sensation seeking and automaticity significantly predicted fruit consumption. Intention and cues significantly predicted unhealthy snacking. There were no significant predictors of walking. Habit, present orientation, sensation seeking, and interactions between intention and sensation seeking, and intention and planning significantly predicted recycling.

Conclusion: Findings may help develop future frameworks to guide research and tailored interventions using the theory according to behaviour type. Behavioural pathways suggested in the theory may be reconsidered, or other constructs could be included as extensions of the model to improve the theory's utility.
