Key components of effective psychological wellbeing practitioners : evidence from routine practice

The purpose of the literature review was to examine the empirical evidence base for therapist effects. Specifically, the review focussed on the methodological issues associated with studying this phenomenon. Seventeen papers were identified that focussed on comparing quantitative treatment outcomes of psychotherapists, nine of which utilised the recommended analytic strategy for examining therapist effects, multi-level modelling. Fifteen of the papers found positive evidence for the existence of therapist effects and the methodological strengths and weaknesses of the papers are discussed. The purpose of the research report was to examine whether therapist effects existed in a sample of Psychological Wellbeing Practitioners (PWPs) operating at step two of the Improving Access to Psychological Therapies programme. A mixed methods approach was employed, utilising quantitative analysis of electronic client data and PWP measures, and qualitative analysis of interview data from PWPs and their supervisors. Outcome data was analysed using multi-level modelling, which resulted in the finding that almost 9% of the variance in outcome scores was attributable to PWPs. Rankings of PWPs were created from the MLM results and the most effective PWPs were found to have higher rates of resilience than less effective PWPs. Qualitative analysis showed that the more effective group of PWPs described approaching their work in a confident and organised manner, and appeared to be at a more advanced practitioner developmental level than PWPs in the less effective group.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
