Exploring the Link Between Sensory Processing and Psychopathology in a Community Sample of Young Adults: Bayesian Network Analyses

Abstract

AbstractSensory processing is a fundamental aspect of human experience, and varies significantly between individuals, potentially affecting individual functioning, behaviour, and mental health. This study investigated the associations between sensory processing and psychopathology in a sample of the general population. Participants responded to a general psychiatric screening tool (DSM-5 Self-Rated Level 1 Cross-Cutting Symptom Measure-Adult) and to the Adolescent/Adult Sensory Profile (AASP) questionnaire. The sample comprised 1108 young adults (77.25% females, mean age 22.6). Data were analysed using item response theory and Bayesian network analyses, revealing specific associations between sensory profiles and psychopathological dimensions. Specifically, we detected associations between the low registration sensory profile and the dimensions of psychosis, substance use, and mania. Sensation seeking was associated with mania. Sensory sensitivity was related to depression and mania, while sensation avoiding was inversely correlated with mania. These findings suggest that reduced external sensory awareness may be linked to a predisposition to psychosis, while a multifaceted sensory processing pattern may indicate vulnerability to mood disorders. Assessing sensory processing could yield crucial insights into individual susceptibilities to mental disorders and help identify targeted preventive and therapeutic strategies
