The Effect of Game-Based Intervention on the Cognition of Schizophrenia Patients

Shanghai Mental Health Center84 enrolled

Overview

Schizophrenia is a common and severe mental disorder that imposes a significant burden on patients. Cognitive impairment can be regarded as one of the core symptoms of schizophrenia, which is prevalent among patients with schizophrenia. In recent years, digital rehabilitation therapy based on games has shown a remarkable development trend among schizophrenia patients. Serious games, or application games, refer to those games aimed not only for entertainment. They can educate, train, or change the behavior of players through interesting intervention forms and have been applied in many healthcare fields. This study aims to develop a somatosensory interactive game for patients with cognitive impairment of schizophrenia to improve their cognitive functions and verify its effectiveness and feasibility through a randomized controlled trial.

Traditional cognitive rehabilitation methods, such as computerized cognitive remediation therapy (CCRT), require a significant amount of time and manpower, and are costly. Patients cannot achieve the best improvement within a short period of time; moreover, they cannot replicate real-life scenarios, and lack real interaction and immersion, which limits the application of training results in daily life. Patients with schizophrenia may have difficulty adhering to treatment due to their sense of stigma and the time and energy costs required for treatment, resulting in poor treatment compliance and significant impact on treatment outcomes. Sensory interactive games are based on multitasking and require the brain to simultaneously integrate low-level and high-level cognitive resources, which have a very good effect on overall cognitive function. This study first determined the cognitive dimensions that needed intervention by reviewing literature, collecting data, and discussing with experts in related fields. The game content was designed referring to relevant cognitive psychology paradigms, existing research foundations, and actual community scenarios. The game was developed using the gyroscope of mobile devices for sensory interactive serious games. Through the design of a randomized controlled trial and the use of standardized measurement tools, the changes in patients' cognitive functions before and after the intervention were quantitatively evaluated from a scientific perspective, providing a scientific basis for the implementation of such intervention measures; at the same time, the quality of life, social function, and motor ability, which are more relevant to actual rehabilitation performance, were evaluated to assess their significance in the entire rehabilitation process.

Outcomes

Primary Outcomes

MCCB

Using MATRIC Consensus Cognitive Battery (MCCB) to measure the cognition. The MCCB includes 9 standardized tests covering domains such as processing speed, attention, and working memory. The raw scores are converted into standardized T-scores based on normative data. Higher T-scores indicate better cognitive performance.
