Examining MEmory Training for Recovery-Adolescent among Afghan adolescent boys: a pilot randomised controlled trial.

Objective: To conduct a pilot randomised controlled trial examining the feasibility, acceptability and efficacy of MEmory Training for Recovery-Adolescent (METRA) in improving psychological symptoms among Afghan adolescent boys following a terrorist attack.Method: A pilot randomised controlled trial compared METRA to a Control Group, with a three-month follow-up. The study occurred in Kabul (June-November 2022). Fifty-eight boys aged 14-19 years (Mage = 16.70, SD = 1.26) with heightened posttraumatic stress disorder (PTSD) symptoms were recruited through a local school that had recently experienced a terrorist attack. Participants were randomised 1:1 to receive METRA (n = 28) (10 session group-intervention) or Control (n = 30) (10 group-sessions of study skills). Primary outcomes were self-reported PTSD symptoms at post-intervention. Secondary outcomes included self-reported anxiety, depression, Afghan-cultural distress symptoms and psychiatric difficulties.Results: There were challenges in youth participation related to security and competing education demands. For those who did complete METRA, METRA was deemed feasible and acceptable. Following the intent-to-treat principle, linear mixed effects models found at posttreatment the METRA group had a 20.89-point (95%CI -30.66, -11.11) decrease in PTSD symptoms, while the Control Group had a 1.42-point (95%CI -8.11, 5.27) decrease, with the group over time interaction being significant (p < .001). METRA participants had significantly greater reductions in depression, anxiety, Afghan-cultural distress symptoms and psychiatric difficulties than did Controls. All gains were maintained at three-month follow-up.Conclusions: With some modifications, METRA appears a feasible intervention for adolescent boys in humanitarian contexts in the aftermath of a terrorist attack.
