Abstract
Management of long-term conditions is a significant challenge in contemporary health care as people often require support for both physical and psychological symptoms. Assessing the competence of healthcare professionals delivering psychologically informed interventions informs decisions about future implementation. This is a comprehensive intervention fidelity assessment nested within a randomised controlled trial. We developed a bespoke intervention fidelity assessment framework to assess the competence of primary care respiratory nurses, physiotherapists and occupational therapists delivering a cognitive behavioural intervention for people with COPD. A total of 180 (representing 15% of trial cases) intervention audio files, from 36 intervention arm participants, were coded. The intervention was delivered with acceptable adherence for most components. Therapeutic competency was achieved and comparable with previous research studies. Interpersonal skills and focus had higher competency whilst guided discovery and application of appropriate change techniques was lower but still adequate. Skills improved over time and with an increased number of clients. With proper training and supervision, primary care respiratory nurses, physiotherapists and occupational therapists can deliver cognitive behavioural interventions with acceptable therapeutic competency but questioning and change techniques may need particular focus in training and greater practice.
