Refugees have more chance of developing psychopathology, which can be explained from the (biosocial) ecological models. Individual and environmental traits influence the development, course and treatment of psychopathology. An unstable environment might cause more stress and mental health issues. The aim of this meta-analysis is to research how effective psychotherapy is for treating PTSD in refugees, and if age as individual factor and language/ cultural adaptation as environmental factor influence the treatment efficacy. Methodology A systematic review with different meta-analyses. Results Systematic researches provided 132 effect sizes within 80 suitable studies. The overall effect size of treating PTSD was significant (Cohen’s d = -0.941, p < 0.001). There were no significant differences between the mean effect sizes of treating PTSD between children, adolescents and adults. There was no difference in treatment efficacy as a function of the level of language or cultural adaptation found. Discussion and conclusion These results show that psychotherapy significantly lowers PTSD symptoms in refugees. However, our results do not find evidence for the proposed (biosocial) ecological models since age and adaptation are not associated with treatment efficacy. Moreover, there is a large difference in treatment efficacy between refugees and non-refugees, this might be caused by the different structural designs between the studies included in this meta-analysis. Future research should consider these different structural designs and should research more environmental factors that can increase treatment efficacy.Show less

Research is just beginning to explore using sleep interventions to reduce suicidality, but until now has not considered how sleep and suicidality change across the lifespan, and how that may impact the effectiveness of interventions. This study is the first meta-analysis examining whether sleep interventions are effective for reducing suicidality, and whether age has an impact on outcomes. A search was conducted on February 8th, 2022, using PubMed, PsycINFO and Web of Science. Article selection and data extraction was performed using the Covidence Systematic Review software. Twenty-one articles were included in this study. Sleep interventions were categorized as cognitive behavioural therapies (CBTs), circadian rhythm therapies (CRTs) and pharmacological therapies (PTs). Age groups were defined as adolescents (15-18), young adult college students (18-24), and adults (18-64). Sleep interventions overall had a small, significant effect size in reducing suicidality. CBTs and CRTs significantly reduced suicidality with small and medium effect sizes, but PTs did not. When stratified by age group, results found that sleep interventions overall significantly reduced suicidality in adolescents and adults with medium effect sizes, but there was no significant reduction in young adults. The results of this study suggest that sleep interventions may reduce suicidality and serve as a versatile and transdiagnostic treatment approach that deserves more focus. It also provides preliminary evidence that age may be a possible moderator for treatment effectiveness, and that future studies should include age as a moderator.Show less

The main hypotheses were that (1) PTSD patients with a history of CSA report a clinically significant decrease in their PTSD symptoms after treatment, and (2) PTSD patients with a history of CSA would profit equally from trauma-focused treatment as PTSD patients without a history of CSA. Methods: Patients were 76 individuals who participated in a five-day treatment program consisting of eye movement desensitization and reprocessing (EMDR), prolonged exposure (PE) sessions, and trauma-sensitive yoga. The severity of PTSD symptoms was assessed with the PCL-5 at pre- and post-treatment, at one-week follow-up, and at a one-month follow-up. Pre-post differences were calculated and compared between the two trauma conditions (i.e., patients with a history of CSA, and no CSA). Results: Treatment resulted in a significant short term decrease of PTSD symptoms, which was mostly maintained at follow-up. Although patients with a history of CSA showed significantly higher PTSD symptom severity at pre- and post-treatment compared to those without a history of CSA, no significant pre-post differences were found between the two groups. Longer term decrease in PTSD symptoms was significant for patients without a history of CSA, but was not strong enough to be significant for patients with a history of CSA. Clinical significance of the treatment was demonstrated for half of the participants. Conclusion: Results suggest that intensive treatment for PTSD might be a possible therapeutic option for PTSD patients with a history of CSA.Show less
