Past studies have presented evidence that depressive symptoms are affected in different ways by social interaction skills and auditory hallucinatory symptoms in people with schizophrenia. However, few studies have focused on examining the relationship among auditory hallucinatory severity, social interaction skills, and depressive symptoms. This study aimed to explore the mediating effect of auditory hallucinatory severity on social interaction skills and depressive symptoms in people with long-term schizophrenia. We propose that auditory hallucination severity functions as a mechanism through which impaired social interaction skills increase depressive symptoms. In this study, a convenience sample of 186 people with schizophrenia was obtained from hospital-based rehabilitation wards. Four instruments were used: A demographic data questionnaire, the Assessment of Communication and Interaction Skills-Chinese version, the Characteristics of Auditory Hallucinations Questionnaire, and the Beck Depression Inventory II. To investigate the mediating effect of auditory hallucinatory severity after controlling for six covariates, we tested an indirect effect in a simple mediation model using the SPSS macro PROCESS, which is a regression-based approach. The indirect effect and the results of Sobel's test were significant (Z = -2.824, P = 0.005), which confirms that auditory hallucination severity mediates social interaction skills and depressive symptoms. This finding suggests that psychiatric nurses must teach people with schizophrenia to use auditory hallucination management strategies to prevent them from becoming immersed in auditory hallucinations and reducing their social interaction with the real world, so that depressive symptoms can be improved.
