Topic: Currently, research into the key elements and role of peer support in the aftermath of victimization is limited. This study reviews the types of evidence available, clarifying key concepts in the literature, examining how research is conducted and identifying key characteristics or factors related to peer support in the aftermath of a victimization experience. Method: A scoping review was performed for peer-reviewed papers using predefined search terms. Studies addressing peer support among victims and survivors of crime, traffic accidents, calamities, suicide, and veterans were included. Selection was based on title and abstract and resulted in 16 papers eligible for review. An inductive thematic analysis was used to synthesize data and findings. Findings: Empirical studies into the key elements and role of peer support in the aftermath of victimization are limited in availability and scattered in terms of approach to research (e.g., methodology, type of respondents, type of peer support) and focus (such as focus on effects on mental health and well-being, on key elements or an evaluation of a support program). Studies mainly have an explorative and interpretative character. Key elements, operationalizations, positive outcomes and negative outcomes of peer support are discussed. Conclusion and discussion: The currently available knowledge on peer support in the aftermath of victimization lacks four points: cross-cultural studies, lived experiences as empirical findings, a variety of victimization events and longitudinal studies. Moreover, it is argued that future research should be improved by adopting a contextual and narrative approach.

Background A substantial number of qualitative studies examined how adult victims of potentially traumatic events (PTEs) experienced support provided by family members, friends, colleagues, and other significant others in the informal network. Importantly, the large majority of qualitative studies focused on the perceived support of victims of specific events such as sexual offences, partner violence, homicide, accidents and disasters. Although it is likely that across specific PTEs there are similarities as well as differences in experienced support from the informal network, to date no systematic review synthesized the results of qualitative studies on support from the informal network following various types of PTEs. The aim of the present systematic review is to fill this gap in the scientific knowledge, which is also highly relevant for victim services, policymakers, and the informal network. Methods A literature search of qualitative studies was conducted using the electronic databases of PubMed, Web of Science, CINAHL, Psych INFO, Scopus, Criminal Justice Abstracts and Picarta. The quality of the identified studies was assessed with the Consolidated Criteria for Reporting Qualitative research (COREQ) checklist, followed by analysis of the results of the identified studies using Qualitative Evidence Synthesis. Findings Seventy-five papers were included in the synthesis, involving 2799 victims of PTEs such as accidents, disasters, homicide, intimate partner violence (IPV), and sexual offences. Saturation was only achieved for IPV. Overall, four major categories of perceived social support were identified, namely, support perceived as supportive, supportive but insufficient, unsupportive, and absent from informal support providers, which included friends, family, neighbors, (if applicable) offender’s family, religious group members, work/school colleagues, fellow victims, the local community, and the social network in general. Across the PTE groups, there were similarities in experiencing positive forms of support (particularly empathy and sharing experiences) as well as negative forms of support (abandonment, avoidance, lack of empathy, and not experiencing support despite victim’s request for help). There were also differences across PTE groups, in particular, victims of sexual and intimate partner violence mentioned a number of other supportive (mobilizing support, no unsupportive responses) and non-supportive (e.g., justification or normalization of violence and minimizing responses) responses. Conclusions The review showed that different actors within the social informal network can play an important role in providing support after victims experience violence, homicide, accidents, and disasters. However, the review revealed that the large majority of qualitative studies were aimed at victims of IPV, and only for this type of PTE was saturation achieved. This indicates that, although this synthesis identified several similarities and differences, it is still too early to draw more definitive conclusions on similarities and differences in experienced social support after various PTEs and that future qualitative studies focusing on other PTEs are much needed.
