Changes in persistent delusions in schizophrenia using guided self-determination: a single case study.

Delusions in persons with schizophrenia who have limited insight have been targeted with different treatment modalities with equivocal results. Working with the Guided Self-Determination method used in shared decision-making and problem solving, a 55-year-old male diagnosed with schizophrenia gained insight into his own delusions during a period of six weeks with individual training. The case study is based on qualitative data, reflection sheets, and interview and field notes from the Guided Self-Determination training. The patient's new insight developed in a process from resistance to receptiveness and then from doubt to reaching a new system in his thoughts.
