DNP 815 Topic 6 DQ 1: Psychosocial Construct

Work backwards from your project rather than forwards from the list, because the four constructs the prompt offers explain different things. Ask what your intervention actually relies on to produce its effect. If it teaches a skill and expects patients to use it unsupervised, the mechanism is confidence in performing the behaviour, and self-efficacy is your construct. If the outcome depends on how people appraise and respond to a demand — a new diagnosis, a caregiving role, a change of regimen — the mechanism is stress and coping. If your population has repeatedly failed to control an outcome and has stopped trying, learned helplessness explains a passivity that looks like non-adherence. If the outcome depends on what happens between appointments, social support is the construct. One of these usually fits noticeably better than the others, and saying why the others fit less well is worth a sentence.

Then do the two things that turn a choice into an application. First, state the mechanism as a chain: the intervention affects the construct, the construct affects the behaviour, the behaviour affects the outcome. Written out that way the project acquires a testable middle step, and if the outcome does not move you will know whether the construct shifted. Second, name a measure, because these constructs are all measurable and a doctoral project that invokes one without measuring it has used it decoratively. General and disease-specific self-efficacy scales exist, coping and perceived stress have validated instruments, and social support has several. Check what has been validated in your population rather than in a general one, and say what you would conclude if the construct moved and the outcome did not — which is the more interesting result and the one worth planning for. Say who administers the instrument and when.
