Behavior Change Coaching: Core Models, Techniques, and Question Traps
What the domain tests
Behavior change coaching questions probe whether you can select and apply a theory-driven, client-centered process rather than simply dispensing advice. Know the major frameworks and when each applies: the Transtheoretical Model (stages of change - precontemplation, contemplation, preparation, action, maintenance) describes readiness, not personality; the Health Belief Model weighs perceived susceptibility, severity, benefits, and barriers; Social Cognitive Theory centers self-efficacy, observational learning, and reciprocal determinism; Self-Determination Theory ranks autonomy, competence, and relatedness as the nutrients of durable motivation; and the COM-B/BMI model sorts influences into capability, opportunity, and motivation.
Core skills
Motivational interviewing (MI) is the engine: OARS (open questions, affirmations, reflections, summaries), rolling with resistance rather than confronting it, and evoking change talk. The decisional balance tool fits ambivalence. Goal-setting should be specific, measurable, and jointly owned - SMART goals work best in preparation/action, not precontemplation. Self-monitoring, stimulus control, and relapse-prevention planning (identifying high-risk situations and coping responses) support maintenance.
Traps to expect
Questions love to reward the client-centered response over the expert response. If an answer has the coach lecturing, prescribing, or arguing, it is usually wrong. Watch for stage mismatches: giving a detailed exercise plan to a precontemplator is a classic distractor. Another trap is confusing self-efficacy (confidence in a specific behavior) with self-esteem (global self-worth). Also distinguish intrinsic motivation from external rewards, which can undermine autonomy.
Rule of thumb
Match the intervention to the stage: raise awareness and explore values in precontemplation, tip the decisional balance in contemplation, build a concrete plan in preparation, problem-solve barriers in action, and plan for lapses in maintenance. When two answers seem right, choose the one that preserves client autonomy and reflects back what the client said.
