January 16, 2026 updated by: Büşra Taşkıner

THE EFFECT OF PSYCHOEDUCATION-BASED MOTIVATIONAL INTERVIEWING ON KNOWLEDGE ABOUT SCHIZOPHRENIA AND HOPE LEVELS IN PATIENTS DIAGNOSED WITH SCHIZOPHRENIA

This study aimed to examine the effect of a psychoeducation-based motivational interviewing intervention on schizophrenia-related knowledge and hope levels among patients diagnosed with schizophrenia. The study employed a randomized controlled experimental design with pre-test, post-test, and one-month follow-up measurements. Participants were recruited from a community mental health center and assigned to an intervention group or a control group. The intervention group participated in a structured psychoeducation-based motivational interviewing program consisting of one preparatory session followed by five main sessions, while the control group continued to receive routine community mental health services. Knowledge about schizophrenia and hope levels were assessed using validated measurement tools.

Detailed Description

The present study aimed to examine the effect of a psychoeducation-based motivational interviewing intervention on schizophrenia-related knowledge and hope levels among patients diagnosed with schizophrenia. The study was conducted using a randomized controlled experimental design with pre-test, post-test, and one-month follow-up measurements.

A total of 44 patients diagnosed with schizophrenia were included in the study, with 21 participants assigned to the intervention group and 23 to the control group. The study was carried out with individuals followed at a community mental health center between January and June 2025.

Participants in the intervention group received a structured psychoeducation-based motivational interviewing program consisting of one preparatory session followed by five main sessions. The sessions were conducted at least once per week, and each session lasted approximately 60 to 90 minutes. Throughout the study period, the control group continued to receive routine community mental health services.

Data were collected using a Demographic Information Form, the Schizophrenia Knowledge Level Scale, and the Schizophrenia Hope Scale. Changes in knowledge and hope levels were evaluated across measurement points.
