Background. Post-traumatic stress disorder (PTSD) is debilitating for patients and society. There are a number of treatment methods albeit not all patients respond to these and an interesting method using electroencephalography-based neurofeedback (EEG-NF) has become more prominent in recent years. This systematic review aimed to assess whether EEG-NF, compared with sham NF, other treatment, or no treatment, is effective for PTSD. Primary outcomes were self-harm, PTSD symptoms, level of functioning and health-related quality of life. Methods. Systematic literature searches for randomized controlled trials (RCTs) were conducted in six databases. Random effects meta-analysis was performed. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation. Results. Four RCTs were included (123 participants). Suicidal thoughts were significantly reduced after EEG-NF compared with a waiting list in a small study. PTSD symptoms were assessed in all studies with different instruments. Results were consistently in favor of EEG-NF with large effect sizes (standardized mean difference À2.30 (95% confidence interval: À4.37 to À0.24). One study reported significantly improved level of executive functioning and one study a reduction in use of psychotropic medication. Complications were scarcely reported. Certainty of evidence was assessed as very low for the four assessed outcomes.Conclusions. Based on four RCTs, with several study limitations and imprecision, it is uncertain whether EEG-NF reduces suicidal thoughts, PTSD symptoms, medication use, or improves function. Although all studies showed promising results, further studies are needed to increase the certainty of evidence.

Background Research increasingly highlight post-migration factors for migrants’ mental health status. We investigated the association between participation in a health promotion program and changes in migrants’ mental health, and if socio-demographic factors and length of time in the new home country, Sweden, influenced a potential association. Methods A five-week health promotion program named ‘Hälsostöd’ [Health Support], led by community health workers, was offered to migrants, primarily asylum seekers and newly arrived immigrants (N = 202). The framework for the program was salutogenic psycho-education, which focused on health effects of migration experiences, lifestyle and health, and the health care system. Mental health was measured at the start and end of the program. We analysed this follow up by using the recommended clinical cut off (i.e. > 11 of maximum 36, with higher scores indicating possible mental illness) in the 12- item version of the General Health Questionnaire (GHQ12). Chi Square test was used to analyse statistical significance of changes, and multinomial logistic regression to analyse associations to sociodemographic factors and length of stay in Sweden. Results The number of participants scoring above the clinical cut off after participation in the program (N = 79, 39.1%) was lower compared to the corresponding number before participation (N = 111, 55.0%), Chi Square = 10.17, p < .001. The majority of the participants had no change 72.3 (N = 146), 21.8% (N = 44) had a positive change, yet 5.9% (N = 12) had a negative change, compared to before participation in the program. None of the investigated sociodemographic factors showed to significantly influence the association. Length of stay in Sweden was trending, with participants with longer stay being more likely to have possible mental illness. Conclusion We conclude that psycho-educative programs, similar to ‘Hälsostöd’, have potential for promoting asylum seekers’ and newly arrived immigrants’ mental health as the evaluation showed a considerable number of positive changes in participants. The result suggests the importance of offering immigrants health promotive programs in close connection with arrival to the new home country. Future research should clarify under what circumstances sociodemographic factors influence the effects of such programs.

Crime victims' emotional display in legal settings has been found to influence credibility judgments. The specific nature of public expectations about crime victims' emotional responses have, however, not been adequately investigated. In an experimental vignette study, respondents in a community sample (N = 404) estimated the likelihood that female and male victims would experience 7 distinct emotions in response to 5 types of crimes. Across all crime types, female victims were expected to experience significantly more situation-focused (anxiety, fear) and inward-focused (guilt, shame, sadness) emotions, and significantly less other-focused emotions (hatred, anger) than male victims. This calls for an increased focus on distinct emotions in future research on victim's emotions. Implications for victims in legal and social settings are discussed.

Crime victims may respond emotionally to victimization in a multitude of ways. However, little is known about how people use victims’ emotional expressions to draw inferences about their psychological status and needs. In two experiments (total N = 340), participants were presented with a victim who reacted to a crime with either anger or sadness. Additionally, victim gender (Experiment 1) and presentation modality (text, video, or audio; Experiment 2) were manipulated. Male, but not female, victims were perceived to have a stronger need for social support when expressing sadness as opposed to anger. The effect was mediated by the fact that victims expressing sadness (vs. anger) were perceived as warmer. Moreover, the effect was consistent across presentation modalities. The results show that victim gender and differences between distinct emotions need to be taken into account to understand the social consequences of victims’ emotional expressions.
