Self-regulation Strategies to Improve Exercise Behavior Among Schizophrenic Patients

12. februar 2013 opdateret af: Michael Odenwald, University of Konstanz

Self-regulation Strategies to Improve Exercise Behavior: A Randomized Clinical Trial in Persons With Schizophrenia Spectrum Disorders

Patients who suffer from diseases of the schizophrenia spectrum are frequently burdened by weight gain. Sport programs have been shown to improve somatic and psychological health. However, the motivation to participate in sports therapy is usually impaired due to illness-related factors such as anhedonia and negative symptoms. Previous attempts to increase participation in sports therapy have used psycho-educational and behavioral attempts that require a lot of resources. In this study the investigators will use a brief method developed in experimental social psychology to build up implementation intentions. This method has been shown to improve psychological test performance in schizophrenia patients but has never been used in a clinical context.

In two psychiatric hospitals, in-patients with schizophrenia who have been examined by a medical doctor, for whom any medical concerns for sports therapy participation have been excluded and who declared their motivation to participate in an existing standard sports exercise program will be recruited for the study. After information on the study and signing of an informed consent patients will be randomly assigned to two treatment conditions. In the control condition, the main therapist will individually deliver a 10-minute psycho-education on the helpfulness of sports to improve the health; this will be repeated in a shorter form in the regular individual treatment sessions over the following weeks. The intervention condition will use a structured procedure of the same duration to build up implementation intentions to participate in the sports therapy. The implementation intentions will briefly be repeated and updated in the following session.

Primary outcome variables will be percentage of attended sport therapy sessions, persistence and compliance. Secondary outcome variables will be Body Mass Index. As confounding variables the investigators will assess amount of anti-psychotic medication in Chlorpromazine equivalents, negative and depressive symptoms, usual sport activities and cognitive impairments.

The investigators expect that building up implementation intentions will increase participation, persistence and compliance of the patients in the sports and exercise therapy program compared to the patients who just have received psycho-education.
