The process of change in psychotherapy for depression: helping clients to reformulate the problem

There is increasing interest in mental health nurses delivering structured short-term evidence-based psychotherapies such as cognitive behavioural therapy (CBT) and interpersonal psychotherapy (IPT); however, while there is evidence of the efficacy of psychotherapy for depression, there is limited understanding of the treatment processes. Data were drawn from audio tapes of CBT and IPT sessions for treatment of depression. The transcripts of the initial, middle and final psychotherapy sessions of 40 clients were analysed. A thematic analysis was conducted to identify what was occurring in the sessions, how the client was describing psychotherapy and how the client was describing improvement or lack of improvement in depressive symptoms. There were differences in descriptions of therapy and the experience of depression between clients who responded and those who did not respond to therapy that were related to improvement in symptoms but not to the specific therapy. These differences were in the client's engagement with the language of therapy, sense of optimism about the particular model of psychotherapy, ability to examine their own role in the problem and desire to engage with new ways of being in their lives. Clients who responded to CBT or IPT had flexibility to develop new ways of thinking and acting, the ability to accept responsibility for their role in the identified problem and were willing to risk change.
