Barriers limiting access to mental health care for lesbian, gay, bisexual, trans, and other sexual and gender minority (LGBT+) university students have not yet been explored in depth. The aim of this study was to explore the barriers and facilitators to mental health help seeking and experiences with service use among LGBT+ university students. Participants were 24 LGBT+ students between 18 and 23 years of age from a university in Chile. Individual semi-structured interviews were conducted and analysed using thematic content analysis. Multiple barriers and facilitators influence mental health help-seeking of LGBT+ students, with some of these barriers being explicitly related to LGBT+ issues (e.g., fear of discrimination or accessing specialised services). Perceived effectiveness of services was closely related to access safe/affirming care. Trans students reported more barriers to help-seeking and negative experiences with professionals than their cisgender peers. Perceptions of university mental health services as safe spaces for LGBT+ students were related to a positive perception of the university regarding LGBT+ issues. Knowing the factors that either hinder or facilitate help-seeking and characterising service use experiences in this population is useful for improving access to mental health services and for the development of policies that promote affirmative care for LGBT+ people.

To investigate the associations of demographic variables, childhood adversities (CAs), and mental disorders (MDx) with onset, transition, and persistence of suicidal thoughts and behaviors (STB) among first-year university students. Poisson regression models within a discrete-time survival framework were constructed using web-based self-report survey data from 72,288 incoming university students across 18 countries (response rate=20.9%; median age=19 years, 57.9% female, 1.4% transgender, 21.0% non-heterosexual). These models examined the associations of four demographic variables, five CAs, and eight MDx with STB outcomes. Lifetime prevalence of suicidal ideation, plans, and attempts was 47.0%, 26.0%, and 9.6%, respectively; 12-month estimates were 30.6%, 14.0%, and 2.3%. In unadjusted analyses, associations were strongest between lifetime onset of suicidal ideation and CAs (RR range 4.4-7.0), particularly parental psychopathology (relative risk [RR]=7.0 [95% CI 6.5-7.7]), followed by MDx (RR range 1.3-3.0). Of the demographic subgroups, transgender students had highest risk of STB (lifetime ideation onset RR=2.4 [2.3-2.6]; ideation-to-attempt transition RR=1.5 [1.3-1.8]). In fully adjusted models, strongest predictors of lifetime ideation onset were emotional abuse (RR=2.1 [1.9-2.2]), major depressive disorder (RR=2.0 [1.9-2.1]), and bipolar disorder (RR=1.8 [1.6-2.0]). Ideation-to-attempt transition remained most strongly associated with panic disorder (RR=1.5 [1.3-1.7]), bipolar disorder (RR=1.4 [1.2-1.7]), and sexual abuse (RR=1.4 [1.2-1.7]). Most predictors were significantly but weakly associated with persistence of ideation and plan, while only physical abuse remained associated with repeated suicide attempts (RR=1.3 [1.0-1.8]). CAs and MDx are strong predictors of both onset of and transition within the STB spectrum, underscoring the importance of implementing early-life prevention interventions.

The literature has shown that including children’s perspectives in intimate partner violence (IPV) field research will improve our understanding of this violence and its impact on the well-being of victims. Furthermore, the literature suggests that children are not passive witnesses. Rather, they use a variety of strategies to cope with IPV. The aim of this research is to understand the experiences and coping strategies of children who have lived through IPV between their parents/caregivers. The participants of this study were nine children between the ages of 8 and 12 years (five girls and four boys). These participants were recruited from a specialized program in Chile focused on the maltreatment of children. Semi-structured interviews were conducted, and a thematic narrative analysis was used to identify recurring themes from the interviews. The results showed that children used a variety of coping strategies when an episode of violence was occurring. The aim of these coping strategies included the following: (a) emotional and behavioral self-regulation, (b) seeking social support, (c) avoiding emotional reactions related to IPV episodes, (d) escaping violent episodes, and (e) intervening to stop the IPV and protect their mothers. Along with these coping mechanisms, the results reveal that children often not only have to confront IPV when it is present in their families but are also potentially subjected to other types of victimization. The findings of this study highlight that children are active subjects with agency in response to episodes of IPV and respond through a range of actions and coping mechanisms. The researchers emphasize the relevance of integrating and validating the voices of children in research, given that children are direct victims of IPV and a high-risk group for other types of child victimization.
