Brief Summary

Researchers have stated in the literature that visual perception is negatively affected in schizophrenia. In recent years, virtual reality interventions have become popular in the treatment of schizophrenia. However, there are no virtual reality studies that directly focus on visual perception. This study was planned to examine the effect of virtual reality intervention on visual perception in individuals with schizophrenia.

Outcome Measures

Primary Outcomes (1)

• Motor-Free Visual Perception Test-3rd Edition-MVPT 3

  MVPT-3 is a widely used scale for the assessment of visual perception. The test consists of nine main subheadings, namely visual discrimination (1-8), shape formation (9-13), visual memory-I (14-21), visual closure-I (22-34), visual discrimination (35-45), spatial orientation (46-50), figure-ground (51-55), visual closure-II (56-60) and visual memory-II (61-65), and consists of 65 items. This test is administered individually to participants between the ages of four and ninety-five. The first 40 items are administered to children between the ages of four and ten, and the remaining 51 items from item 14 to item 65 are for individuals aged ten and over. In the study conducted by Metin and Aral for Turkish validity, the Cronbach's alpha coefficient of the test was determined as 0.85.

Virtual reality group

EXPERIMENTAL

The intervention procedure was planned to consist of 8 weeks, 3 days a week and 45-minute sessions in total. In this intervention group, a virtual reality intervention was applied in addition to the client-centered intervention applied to both groups.

Behavioral: Virtual reality; Behavioral: Client-centered

Control group

EXPERIMENTAL

Client-centered intervention procedure was applied to the control group. The intervention procedure was planned to consist of 8 weeks, 3 days a week and 45-minute sessions in total.

Behavioral: Client-centered

Interventions

Virtual reality BEHAVIORAL

The virtual reality intervention program was carried out in a 30-meter2 area covered with soft ground to prevent injuries. "The Microsoft Kinect for Xbox 360" was used for the virtual reality intervention. For the current study, a team of experts was formed to select the games to be used within the virtual reality intervention program. This team determined which skills were required for the games to be run successfully, which skills could be developed, which games were purposeful, and independently observed each game. As a result, 9 different games were chosen. Since all games involve similarly intense visual, cognitive and motor skill requirements, game selection was left to the participants' preference during the intervention process to encourage motivation and participation. The virtual reality intervention procedure was created by utilizing the literature

Virtual reality group

Client-centered BEHAVIORAL

The client-centered (CC) intervention procedure for individuals with schizophrenia was created using literature and the intervention procedure is presented below: 1. Active Communication and Evaluation 2. Daily Routine, Roles, and Occupational Performance 3. Strengths and Barriers 4. Intervention Program Development 5. Implementation of the intervention program 6. Feedback and Revision:

Control group; Virtual reality group
