Psychosis is a challenging phenomenon for professionals. In the need-adapted approach (NAA), therapy meetings constitute a deliberate effort to meet the challenges by bringing all the main parties together within a common discussion. The aims of this study are to analyze and evaluate psychiatrists' experiences of the treatment processes in psychosis. A qualitative multiple case study approach has been used. Between August 2007 and January 2009, co-research interviews (CR-Is) and stimulated-recall interviews (STR-Is) with 10 psychiatrists from 3 different parts of Finland were videoed and transcribed verbatim. The material was analyzed using qualitative content analysis. The difficult emotions of the professionals and the critical views expressed had a prominent role. It was almost impossible to proceed with the treatment until the memories of coercive acts had been addressed. There were fewer harmful effects in outpatient than in inpatient care. If the client-centered principles of NAA were not followed, the CR-Is functioned primarily as critical evaluations of the treatment processes. The STR-Is helped the psychiatrists to find words for difficult experiences. For the sake of both practice and research, the experiences of staff in the treatment of psychosis should be taken into account. For better prediction of failure, routine measures to obtain feedback could be included in NAA.
