PTSD Symptoms Are Associated with a Greater Use of Social Camouflaging Strategies in an Eating Disorder Sample with Elevated Autistic Traits

<b>Background</b>: Eating disorders (EDs) frequently co-occur with trauma-related symptoms and elevated autistic traits (ATs), both of which contribute to clinical complexity. Social camouflaging, strategies used to mask or compensate for ATs, has been increasingly described in ED populations, yet its relationship with trauma-related symptoms remains poorly understood. This study aimed to examine the association between social camouflaging and post-traumatic stress symptoms in individuals with EDs and to evaluate whether trauma-related symptomatology is associated with camouflaging behaviors. <b>Methods</b>: A total of 67 ED patients were assessed using the Adult Autism Subthreshold Spectrum, the Trauma and Loss Spectrum-Self Report (TALS-SR), the Camouflaging Autistic Traits questionnaire (CAT-Q), and the Eating Disorder Inventory (EDI-2). Participants were divided into high-trauma-symptoms (HTS) (N = 36, 53.7%) and low-trauma-symptoms (LTS) (N = 31; 46.3%) groups based on TALS-SR criteria. <b>Results</b>: The sample was predominantly female (92.5%), and gender distribution differed between groups, which may represent a potential confounding factor and limits the generalizability of the findings. The HTS group reported significantly higher TALS-SR, EDI-2, CAT-Q, and AdAS Spectrum scores, although for the latter the <i>p</i>-value was barely significant (<i>p</i> = 0.046). No differences emerged in the distribution of ED diagnoses between groups. CAT-Q scores were significantly positively correlated with TALS-SR total scores and with domains related to reaction to losses, maladaptive coping, avoidance/numbing, and personal vulnerability. Regression analyses showed that overall trauma-related symptoms were significantly associated with greater camouflaging; however, the proportion of explained variance was modest, suggesting that trauma-related symptoms represent only one of multiple factors linked to camouflaging. <b>Conclusions</b>: Among individuals with EDs, higher trauma-related symptomatology is linked to greater use of social camouflaging strategies. These findings suggest that camouflaging may represent a transdiagnostic correlate connecting neurodevelopmental vulnerability and trauma responses within ED populations, underscoring the importance of integrated assessment and trauma-informed care.
