Developing a causal model of adolescent vulnerability to addiction based on the sensitivity of sensory processing and behavioral brain systems with the mediation of childhood trauma

Adolescents are heavily influenced by social and cultural changes that are exposed to harmful environmental stimuli such as addictive; Therefore, the present study was conducted with the aim of investigating the causal model of adolescent vulnerability to addiction based on the sensitivity of sensory processing and brain-behavioral systems with the mediation of childhood trauma in the city of Mashhad. The present study was a descriptive correlation in terms of its practical purpose and the method of data collection. The statistical population of the research was all secondary school students of the second year of Mashhad in the academic year of 1402-1401. 228 students were selected by cluster sampling method. In order to collect data, Enisi's questionnaires for identifying people at risk of addiction, Aron's and Aron's sensory processing sensitivity, Carver's and White's brain-behavioral systems, and Bernstein et al.'s trauma questionnaire were used. The collected data were analyzed using structural equation modeling method and SPSS27 and Lisrel8.8 software. The results of the research showed that the sensitivity variables of sensory processing and behavioral brain systems have a direct and significant effect on vulnerability to addiction. The results related to the fit indices of the model also showed that childhood trauma can mediate the sensitivity of sensory processing and behavioral brain systems with vulnerability to addiction.
