Problematic smartphone use and related factors in young patients with schizophrenia.

Abstract

The present study aimed to examine smartphone use in young patients with schizophrenia and to explore factors that may affect the severity of problematic smartphone use. A total of 148 schizophrenia patients aged 18 to 35years completed self-administered questionnaires exploring sociodemographic characteristics; Smartphone Addiction Scale (SAS), the Big Five Inventory-10 (BFI-10), the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale (PSS), and the Rosenberg Self-Esteem Scale (RSES). All were also assessed using the Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) Scale and the Personal and Social Performance (PSP) Scale. The mean subject age was 27.5±4.5years. No significant differences in the SAS scores occurred between gender, jobs, and level of education. The Pearson r-correlation test showed that the SAS scores were significantly positively correlated with HADS anxiety, PSS, and BFI-10 neuroticism scores; it was negatively correlated with RSES, BFI-10 agreeableness, and conscientiousness scores. In the stepwise linear regression analysis, the severity of PSU was significantly associated with both high anxiety and low agreeableness. Our results suggest that specific groups of patients with schizophrenia may require special care to prevent problematic smartphone use.
