The Transtheoretical Model based psychoeducation's effect on healthy lifestyle behaviours in schizophrenia: A randomized controlled trial

Objective: The study was conducted with the pretest-posttest randomized controlled trial design to detect the psychoeducation's effect, based on the Transtheoretical Model, on the healthy lifestyle behaviours of individuals with schizophrenia.Methods: The data were collected from 82 participants, as 41 intervention and 41 control. The data were collected via personal information form, behavioural change stage diagnosis form and healthy lifestyle scale II. 6-week psychoeducation, consisting of 6 modules, based on the Transtheoretical Model, was applied to the interven-tion group. No interventions were applied to the control group. Pretests and posttests were applied to both groups.Results: When the healthy lifestyle scale II of intervention and control groups and final test results arranged according to ANCOVA analysis are compared, average final test results were meaningfully positive for the intervention group with taking control of the pretest and other covariants. When the pretest-posttest results in terms of behavioural change of the intervention group are evaluated; a meaningful difference among nutrition, physical exercises, spiritual self-improvement and stress management, which all are the stages of behavioural change, was detected.Conclusion: It was determined that psychoeducation on a healthy lifestyle, based on the Transtheoretical Model in an individual with schizophrenia affected physical exercises, spiritual self-improvement and interpersonal re-lationships sub-dimension in medium level, and had a drastic influence on health responsibility, nutrition, stress management sub-dimensions and all healthy lifestyle behaviours. Progress in behavioural change stages was detected.Clinical trials ID: NCT05259748.
