Sensory modulation and daily-life participation in people with schizophrenia

Research output: Contribution to journalArticlepeer-review


Schizophrenia is considered to be an extreme mental health disturbance that affects a person's well-being and participation in everyday activities. Participation in meaningful everyday occupations is an important component of recovery from mental illness, the ultimate goal of mental health services. The participation restrictions of people with schizophrenia have been widely investigated through different factors, such as illness symptoms and course, cognition, and demographic data; however, the resulting explanations were incomplete. The purpose of the study was to explore the contribution of sensory modulation (SM), in addition to cognition and schizophrenia symptoms, to participation in daily life activities of people with schizophrenia. Forty nine in-patients with schizophrenia (study group) and 32 adults without mental illness (control group) comprised the study. They were assessed for their participation patterns, sensory modulation processes, cognitive functioning and symptoms severity. Results indicate significant differences between the study groups in most measurements addressed: participation (diversity and satisfaction), sensory modulation scores (intensity of the response and frequency of response), and cognitive measurements. The most contributive parameters for the prediction of participation dimensions among people with schizophrenia were negative symptoms severity and general cognitive status. In conclusion, people with schizophrenia experience SM disorder with an under responsive tendency. However the complex condition of schizophrenia dominates its influence on participation dimensions.
