Psychosocial and Behavioral Aspects of Physical Activity
Domain 8: Psychosocial and Behavioral Aspects of Physical Activity
This domain tests motivation, behavior change, group dynamics, and mental health. Expect questions that ask why an intervention works, not just what it is called.
Core rules
- Self-determination theory: autonomy, competence, and relatedness support intrinsic motivation. Extrinsic rewards can undermine intrinsic motivation when controlling, but can help early adherence.
- Transtheoretical model: precontemplation, contemplation, preparation, action, maintenance. Match strategies to stage; action-focused plans fail in precontemplation.
- Self-efficacy comes from mastery experiences, vicarious experience, verbal persuasion, and physiological/affective states. Mastery experiences are usually strongest.
- Goal setting: specific, measurable, achievable, relevant, time-bound. Process and performance goals often outperform outcome-only goals.
- Motivational climate: mastery climate emphasizes effort and improvement; ego climate emphasizes comparison and winning. Mastery climates tend to support persistence.
- Adherence improves with self-monitoring, social support, convenient scheduling, and relapse prevention.
Worked example
An inactive adult says, “I know I should exercise, but I keep putting it off.” This is contemplation, not action. A coach avoids a rigid program and instead explores barriers, sets a 10-minute walk three times per week, uses a step counter, and recruits a walking partner. Early mastery builds self-efficacy; the plan is then progressed. Giving a demanding five-day program immediately would likely confirm low confidence.
Traps
Not all motivation is intrinsic, and extrinsic motivation is not always harmful. A client’s stated goal may be an outcome goal; convert it into process goals. Correlation is not causation in activity research. Also, “more education” alone rarely changes behavior; skills, support, and confidence matter.
