Twenty-eight schizophrenic and other long-term mentally ill patients who were given cognitive therapy sessions twice a week in the context of a comprehensive inpatient treatment program were assessed every 5 weeks regarding perceived curative factors. The assessments were made by a self-rating questionnaire (Curative Factors Questionnaire [CFQ]) and a qualitative assessment from the patients of what they perceived as helpful in treatment. The results showed that milieu therapeutic elements and therapy sessions were perceived as the most helpful throughout the treatment period. No correlations were found between patient characteristics and perceived curative factors. The factors “instillation of hope”, “problem solution” and “learning I’m not alone” as rated in the initial phase of treatment showed a positive relationship with a favourable outcome of treatment at discharge.
