Mediation role of alexithymia, sensory processing sensitivity and emotional-mental processes between childhood trauma and adult psychopathology: a self-report study
Abstract Background There is overwhelming evidence for a strong association between childhood trauma and adult psychopathology. This study aims to investigate the mediation roles of alexithymia, sensory processing sensitivity, and emotional-mental processes in the relationship between childhood traumas and adult psychopathology. Methods 337 people (78.9% female, 21.1% male) between the ages of 20–64 participated in this study. Participants filled the scales online via google form. Reading Mind in the Eyes (EYES), Sensory Processing Sensitivity Scale (SPS), Toronto Alexithymia Scale (TAS-26), Childhood Trauma Questionnaire (CTQ), and the Brief Symptom Inventory (BSI) were used. SPSS Process (Model 4) was used to examine the mediating role of sensory processing sensitivity, alexithymia and the eyes test results in the relationship between childhood trauma and psychopathology. Results Sensory processing sensitivity and alexithymia have been found to mediate the relationship between childhood trauma and adult psychopathology. The eyes test (mentalization) was not found to have a mediating effect on this relationship. Conclusion This study shows that childhood traumas may relate more psychopathology in individuals with high sensory processing sensitivity and alexithymia. Our study may contribute to the understanding of what may lead to a person's vulnerability to experiencing psychopathology after childhood trauma. It may be important that future treatment and intervention programs should include sensory sensitivity and alexithymia. Sensory processing sensitivity and alexithymic characteristics of individuals can be examined in the treatment of psychological problems of individuals who have experienced childhood trauma.
