Items will require identification of key constructs (e.g., self-efficacy, observational learning, stages/processes of change, autonomy, competence, relatedness), explanation of theoretical assumptions and mechanisms of change, comparison of intervention implications and measurement strategies, and application of theories to evaluate or design program components.
