Predicting smoking behavior: intention and future self-continuity among Austrians.

Area of Science:

• Health Behavior
• Psychology
• Public Health

Background:

• Smoking remains a significant public health issue in Austria, with limited research and interventions.
• The Theory of Planned Behavior (TPB) is a framework for understanding health behaviors.
• Future self-continuity may influence health-related decisions, warranting its inclusion in behavioral models.

Purpose of the Study:

• To assess the applicability of the TPB to smoking behavior in an Austrian population.
• To investigate whether incorporating future self-continuity enhances the TPB's explanatory power for smoking.
• To identify key psychological factors influencing smoking intention and behavior.

Main Methods:

• A prospective study design was employed with 94 current smokers from a South Austrian university.
• Participants completed baseline and one-month follow-up surveys assessing TPB constructs and future self-continuity.
• Statistical analyses were used to test the predictive utility of the TPB and its extended model.

Main Results:

• Perceived behavioral control (PBC) and intention significantly predicted smoking behavior, aligning with the TPB.
• Affective attitude and PBC were associated with smoking intention, while cognitive attitude and subjective norm were not.
• The TPB explained 42% of the variance in smoking behavior and 31% in smoking intention.
• Future self-continuity further accounted for variance in smoking behavior.

Conclusions:

• The TPB is a useful model for understanding smoking behavior in Austria.
• Affective attitude and PBC are key targets for smoking interventions.
• Future self-continuity plays a role in smoking behavior, suggesting interventions should consider long-term perspectives.
