MethodTo uncover therapeutic micro-processes from the perspectives of eating disorder (ED) treatment non-responders with childhood trauma (CT) late effects, we explored in-session experiences of poor long-term outcome patients. Female inpatients aged 28–59 (M = 40.2, SD = 5.0) from a randomised trial comparing Compassion Focused Therapy for EDs (n = 3) with Cognitive Behavioural Therapy for EDs (n = 3) were interviewed with video-assisted recall about a self-selected session. Data were analysed through Interpretative Phenomenological Analysis (IPA) with Grounded Theory (GT) elements.ResultsCovert patient strategies included self-effacement, regulating therapeutic distance to open up, and engaging with reflective rather than experiential interventions. First, self-effacement included submissive, passive or pretend responses to perceived criticising or violating therapist behaviours as well as other orientation and submission for approval. Second, some preferred a close patient–therapist alliance with therapist self-disclosure and reciprocity was a requirement for opening up; others required distance. Third, informants detached from experiential trauma work while engaging in joint reflection on post-trauma responses.ConclusionInformants were preoccupied with calibrating the emotional–relational landscape in session; we hypothesized that psychological insecurity and affective intolerance from CT limit their freedom to explore own in-session experiences.
