Strengths and limitations
cognitive behavior
A strength of this study is that it reached a population that, to our knowledge, has not previously been represented in the literature. Thus, the results presented here are important for future studies aiming to attract this population. However, it is possible that the decision to include only participants who completed One limitation is that the sample of SOs in our study was ethnically homogenous, with a high level of education, and thus does not reflect the Swedish population. However, we consider the current sample representative of the group of SOs who participated in the RCT and believe the results of the interviews are transferable to the larger study population.An aspect regarding credibility involves the authors’ perspectives and experiences. The first author is a clinical psychologist specialized in cognitive behavior therapy and was involved in all parts of the RCT. The second author has a background in social work and was not involved in the quantitative evaluation. The close involvement of the first author comes with a risk of bias, potentially leading to more positive interpretations of data than by a “neutral” observer. This risk was highlighted already from the start of the study and we tried to counteract it by continuously discussing the analyses and results back and forth between the authors.
