Trait-Based Correlates of Post-traumatic Stress Symptoms in Occupational Injury Sample: Sensory-Processing Sensitivity, ADHD Symptoms, and Dispositional Mindfulness

Abstract

Background: Occupational injuries are associated with substantial post-traumatic stress symptoms, yet brief trait-based markers of vulnerability remain underexplored. This study examined whether sensory-processing sensitivity, adult attention-deficit/hyperactivity disorder (ADHD) symptoms, dispositional mindfulness, and workload factors are associated with post-traumatic stress disorder (PTSD) symptom severity following workplace injury. Methods: Forty-seven adults with documented occupational injuries, assessed 1–12 months post-accident at a university hospital psychiatry outpatient clinic, completed the Impact of Event Scale-Revised (IES-R), the Highly Sensitive Person Scale (HSPS), the Adult ADHD Self-Report Scale version 1.1 (ASRS v1.1), and the Mindful Attention Awareness Scale (MAAS). Group differences were examined with Mann–Whitney U tests, associations with Pearson correlations, and hierarchical multiple regression with IES-R total as the dependent variable. Results: High PTSD-risk participants (IES-R ≥ 33) showed higher ASRS and HSPS scores and lower MAAS scores. Bivariate analyses indicated that IES-R total correlated positively with HSPS, ASRS, and weekly working hours, and negatively with MAAS and time since injury. In the final regression model, HSPS (β = 0.60, p < .001) and weekly working hours (β = 0.35, p = .002) remained significant independent predictors, whereas ASRS and MAAS were not. Conclusions: Sensory-processing sensitivity and workload intensity emerged as key correlates of PTSD symptom severity after occupational injury, beyond ADHD symptoms and dispositional mindfulness. Routine assessment of sensory sensitivity and work demands may support early risk stratification and more tailored interventions for trauma-exposed workers.
