Research in clinical psychology and social psychiatry has highlighted the importance of social factors for outcomes following trauma. In this review, we speak to this issue in two ways. First, we highlight the value of a social identity framework for understanding the experience and impact of psychological trauma. Second, we draw on the Social Identity Model of Identity Change (SIMIC) to understand reactions to trauma. Specifically, we show (a) that negative responses to trauma are more apparent where trauma serves to undermine valued social identities; (b) that people prove more resilient in the face of trauma when valued social identities can be maintained or new social identities developed; and (c) that where old or new positive identities are reinvigorated or extend the self, this can be a basis for post-traumatic growth. We conclude by discussing the implications of this model for practice, and emphasise the importance of social identity management in the aftermath of trauma.

Background: Despite a high prevalence of suicide ideation and mental health issues amongst university students, the stigma of help-seeking remains a barrier to those who are in real need of professional support. Social identity theory states that help received from an ingroup source is more welcome and less threatening to one's identity than that from a source perceived as outgroup. Therefore, we hypothesized that students' stigma toward seeking help from their university mental health service would differ based on the strength of their identification with the university.Method: An online survey including measures of stigma of suicide, group identification, experience with help-seeking and exposure to suicide was administered to Irish university students (N = 493).Results: Group identification was a significant predictor of help-seeking attitudes after controlling for already known predictors. Contrary to our expectations, those who identified more strongly with their university demonstrated a higher stigma of seeking help from their university mental health service.Conclusions: Results are discussed in relation to self-categorization theory and the concept of normative fit. Practical implications for mental health service provision in universities are also addressed, specifically the need for a range of different mental health services both on and off-campus.

Suicide is recognised to be subject to social contagion, with an elevated risk of adverse outcomes amongst those affected. Drawing upon research within the social identity approach, we hypothesised that, for those bereaved by suicide, identifying with similar others could provide ‘a social cure’. A large cross‐sectional study and a longitudinal study were carried out at a charity fundraiser for suicide prevention, with participants completing an online survey before and after the event. Results showed that, for those who lost someone they knew (Study 1) or a family member (Study 2) to suicide, there was a significant increase in psychological well‐being after the event. This was mediated by identification with the crowd. These findings demonstrate that collective participation in a suicide awareness event can be an effective social intervention for those bereaved by suicide in terms of psychological well‐being, with implications for informing best‐practice interventions targeting this at‐risk group.

A principle characteristic of public speaking anxiety relates to intrusive mental images of potential future disasters. Previous research has found that the self-reported emotionality of such “flashforwards” can be reduced by a cognitively demanding, dual-task (e.g., making eye movements) performed whilst holding the mental image in-mind. The outcome measure in these earlier studies was participants’ self-reported emotional intensity of the mental image. The current study (N = 34) explored whether an objective measure of emotionality would yield similar results in students with public speaking anxiety. A script-driven imagery procedure was used to measure psychophysiological responsivity to an audio script depicting a feared (public speaking) scenario before and after an eye movement intervention. Relative to the control condition (imagery only), those who made eye movements whilst holding a mental image of this scenario in-mind demonstrated a significant decrease in heart rate, which acted as a measure of emotionality. These findings add to a previous body of research demonstrating the beneficial qualities of dual-tasks and their potential for treatment of both past and future-oriented anxieties.
