​Research aim: To investigate the effectiveness of psychiatric treatment for trauma-affected refugees, focusing on symptom profiles, treatment outcomes, and predictors of these outcomes. The goal is to identify which therapeutic components work best for different patient subgroups, improving evidence-based treatment differentiation.

Design: The study uses data from five randomized controlled trials (RCTs) conducted at the Competence Centre for Transcultural Psychiatry (CTP), involving a large cohort of trauma-affected refugees (N = 1,196). Advanced statistical methods, such as Latent Growth Mixture Modeling, network analysis, and machine learning, will be applied to analyze treatment outcomes.

Population: The study population includes 1,196 trauma-affected refugees who participated in previous RCTs at CTP.

Methods: Data from the five RCTs, which include both psychotherapy and medication interventions, will be analyzed using state-of-the-art statistical techniques to identify subgroups with different treatment trajectories. The study will explore the relationship between patient characteristics (e.g., demographics, symptom severity, chronicity) and treatment outcomes, aiming to tailor treatment approaches to specific patient needs, including factors like interpreter use and cultural matching.
