Abstract:Psychological issues among military servicemen are prevalent, with numbers reaching from 4% to even 44% of soldiers suffering from mental health issues. Acceptance and Commitment Therapy (ACT) has shown to be a promising treatment to increase mental health and decrease psychological symptoms. The present study examined the effect of the ACT-based group intervention Living to the Full for the psychological treatment of military servicemen with distress. Questions were examined whether attending the intervention leads to psychological benefits in terms of positive mental health, anxiety-related symptoms and negative self-thoughts, whether core processes of ACT, including mindfulness and acceptance increase in the course of the intervention and whether scores of mindfulness and acceptance predict outcomes of positive mental health. Attending the intervention led to a statistically significant increase in positive mental health (Cohen’s d = - 1.02) and a decrease in anxiety-related symptoms (Cohen’s d = 1.27) and negative self-thoughts (Cohen’s d = 0.35). Moreover, the processes mindfulness and acceptance were both significantly improved. Regression analysis revealed a relation between mindfulness and positive mental health, but not between acceptance and positive mental health. Findings suggest that the ACT-based intervention Living to the Full is effective for the treatment of servicemen suffering from psychological issues.
