Improving Insight in Patients Diagnosed With Schizophrenia

Background:

Rehospitalisation and discontinued treatment are common among patients with schizophrenia and is often associated with lack of insight into the illness. Improving patients' insight has been attempted through psychoeducation and standard treatment but without any considerable change. A newly developed method, Guided Self-Determination (GSD), originally developed and proved effective in difficult diabetes care has been adjusted to patients with schizophrenia. A qualitative evaluation of GSD has shown a positive influence on patients' insight into the illness.

Aim and hypotheses: The aim of the study is to evaluate the effects of the method GSD in the care of patients with schizophrenia compared to treatment as usual. The following hypotheses will be tested:

The method GSD will improve: Cognitive and clinical insight in patients, various domains of recovery, patients' self-esteem, psychopathology and social functioning.

Material and method:

The study design is a randomised controlled trial. The participants are diagnosed with schizophrenia and schizoaffective disorder, receiving treatment in 3 Assertive Outreach Teams and 3 Psychosis Teams in Region North. Participants complete four self-rating questionnaires, a demographic data sheet, an interview concerning psychopathology and an assessment of social functioning at baseline, and after 3, 6, and 12 month. All assessments will be conducted by the investigator, except for the assessment of social functioning, that will be measures by community nurses. Intervention with the method GSD will also be conducted by the community nurses but under supervision from the investigator. Fifty patients are randomly assigned to immediate receipt of individual training with the method GSD (intervention group) and 50 to a 12-month waiting list for individual training with the method GSD (control group).

Perspectives:

In mental health nursing practice in Denmark there is no tradition for empirical research as the basis of psychiatric nursing - unverified theories or general empirical consensus of good clinical practice are often the foundation of psychiatric nursing. If the method GSD proves effective in the care of patients with schizophrenia, this study contributes to an evidence based nursing intervention, which is ready for further research on implementation in mental health nursing practice.
