Interpersonal theories and SCT in health promotion

The first question carries an unusually direct instruction: apply an interpersonal-level theory to changing a health behaviour, then use the constructs of Social Cognitive Theory the same way, and the brief adds that it wants the construct and an example, not the definition. Obey that literally, because it is also good advice — a post that defines self-efficacy and stops has demonstrated recall, while a post that says what raising self-efficacy would look like for one named person changing one named behaviour has demonstrated application. Note too that the brief forbids reusing the textbook's example, so the illustration must be your own. Interpersonal-level theories are the ones operating between people rather than inside a single head, which is what rules out the Health Belief Model and rules in Social Cognitive Theory and social network approaches, so check the level of your theory before you commit to it.

Work through the Social Cognitive Theory constructs deliberately rather than listing them: reciprocal determinism, observational learning, outcome expectations, self-efficacy, behavioural capability, reinforcement. For each one you use, name the specific thing you would do — who the person watches, what expectation you are correcting, which small success builds the efficacy, what reinforcement is available and from whom. That level of specificity is what the instruction is asking for. The second question shifts register entirely: it wants your own programme's theoretical framework, the priority population and need, why the problem fits the theory, and a recognised graphic illustrating it. Do not sketch your own diagram when a published model figure exists and can be cited properly, and make sure the fit argument runs both ways — the theory has to explain your problem, and your problem has to exercise the theory, and a framework that would fit any health problem equally well is not doing any work.
