Predicting response to interpersonal counselling (IPC) from case formulation: a systematic comparison between recovered and unchanged depressive cases

Abstract

Objective: We sought to explore how the process between the counsellor and patient for arriving at a case formulation may predict the outcome of manualized interpersonal counselling (IPC) for depression in primary care. Method: Qualitative content analysis and applied conversation analysis (CA) were used to achieve depth in the understanding of case formulation process among five patients who recovered and five who were unchanged according to quantitative post-treatment change rates derived from Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM). Results: Interaction in the case formulations for the recovered group was generally characterized by a joint construction effort between the counsellor and the patient centred on one problem area. The ability to delimit problems to one area was associated with the patient's role disputes in social relationships. For the unchanged patients, the case formulation typically reflected unilateral construction of the problem area, and more than one problem area was selected as the focus. The problem areas in the unchanged group were associated with complicated grief or loneliness. Conclusions: The process between counsellor and patient of arriving at and agreeing on a case formulation might potentially contribute to recovery, and it deserves greater attention in training counsellors and conducting research.

“…The question is how different ways of conducting the entire therapy process vary in their outcome. Such research is still scarce (although see Kontunen et al 2019;Savander et al 2019).…”
