Method
This study is part of a larger RCT study (PIAAS study) in which 88 Afghan asylum seekers and refugees were randomly allocated either to aPM + in addition to treatment as usual (aPM+/TAU) or TAU alone. The presented study uses a multi-method approach consisting of two parts: First, we investigated participants’ self-identified problems and subjective functional impairment using quantitative and qualitative assessment in both the aPM+/TAU and TAU group (n = 88). Second, we conducted in-depth qualitative interviews with a subsample of the aPM+/TAU group (n = 24) to gain a deeper understanding of participants’ personal experiences with aPM + and to obtain suggestions for improvement. Spearman correlations were applied for quantitative data, and deductive and inductive approaches of thematic analysis were used for qualitative data.
