The Development of a Physical Activity Persona Profile Classification for Public Education Campaigns

Area of Science:

• Behavioral Science
• Health Psychology
• Exercise Science

Background:

• Traditional social cognitive approaches inadequately explain the physical activity (PA) intention-behavior gap and differentiate between adoption and maintenance.
• Action control and dual-process theories offer a framework for understanding intention-behavior translation.

Purpose of the Study:

• To develop and validate a concise classification system for physical activity (PA) behavior.
• To address the translation of PA intentions into behavior and its maintenance.
• To utilize PA intentions, behavior, habit, and identity as key classification components.

Main Methods:

• A 4-item classification was developed using PA intentions, behavior, habit, and identity.
• The classification was initially developed on a large population (n=1350).
• Validation was performed on two independent physical activity (PA) campaign populations (n=376 and n=6396).

Main Results:

• The initial classification yielded four profiles: nonintenders, unsuccessful adopters, successful adopters, and successful maintainers, accounting for 87.6% of the sample.
• Test samples predominantly revealed two profiles: successful adopters (69.8%) and successful maintainers (70.9%).
• These profiles represent distinct stages of physical activity (PA) engagement, from intention to sustained behavior.

Conclusions:

• The developed classification effectively categorizes individuals based on their physical activity (PA) engagement.
• The prevalence of 'successful adopters' and 'successful maintainers' in campaign populations suggests a tendency towards intention-behavior translation and maintenance.
• Future research should explore profile distribution across diverse populations to refine the classification's generalizability.
