Evaluating the effect of building self-efficacy on outcomes of total knee replacement surgery (TKR)

This study evaluates a brief self-efficacy guided reminiscence intervention conducted over the phone. This intervention will involve a 5-minute conversation where a researcher prompts participants to recall a time in their life they have overcome a challenge, and think about the strength they demonstrated during this time before and whilst doing their prescribed physiotherapy knee exercises at home. The participant will not share their challenging experience with the researcher, they will simply personally recall it. This intervention is developed in consultation with clinicians and patients who have undergone TKR surgery, and is designed to elicit self-efficacy through past memory of mastery experiences. Participants will receive the intervention once in an individual phone call, between their two physio appointments in either week 3 (Group A: intervention arm) or week 4 (Group B: waitlist control arm) after total knee replacement (TKR) surgery. Adherence to the intervention will be assessed in a feedback survey designed for the purposes of the study, sent to participants at the end of the two-week period. This survey will ask participants if they thought about the hard experience they overcame before or during their exercises. If the answer is yes, they will be asked to state how often, and if no, they will be asked to describe the reasons why they did not.
