Abstract

The present study investigated differences in MMPI-2-RF scale scores between individuals with and without a history of mild traumatic brain injury (mTBI). The goal was to identify distinct psychosocial functioning patterns in individuals with mTBI. Archival outpatient sample of 147 adults aged 18 to 70 (M = 43.28, SD = 11.13) was utilized, comprising 65 participants with mTBI and 82 without TBI. Significant differences were observed across multiple MMPI-2-RF scales. The group with mTBI history exhibited higher levels of symptom overreporting, symptom validity concerns, emotional and internalizing dysfunction, somatic and cognitive complaints, and negative emotionality, as compared to the non-mTBI group. Effect sizes ranged from medium to large (Cohen’s d range: 0.46 – 1.09). These findings highlight the need for comprehensive multidisciplinary assessments and psychosocial interventions for individuals with mTBI history. Such approaches can significantly enhance the psychosocial well-being of individuals affected by mTBI, ultimately improving their overall quality of life.
