Immigration Status, Legal Vulnerability, and Suicidal/Self-harm Ideation Disparities Among Immigrant-Origin Latinx Young Adults in the U.S

Theories of suicidality typically center intrapersonal processes, with limited attention to social determinants of mental health disparities. Using a legal vulnerability framework, we examined the association between self/parental immigration status and suicidal and self-harm ideation (SI) disparities in three groups of immigrant-origin Latinx young adults attending college in the USA: undocumented students (n = 564), US citizens with undocumented parents (n = 605), and US citizens with lawfully present parents (n = 596). We also evaluated whether self/parental immigration status differences in SI could be accounted for by six dimensions of legal vulnerability and, based on prominent theories of suicidality, explored the role of campus belongingness as a protective factor. Participants completed self-report measures, and SI was assessed using one item from the Patient Health Questionnaire-9, a screening tool that assesses the severity of depression symptomatology. Rates of SI were significantly higher among undocumented students (23.1%) and US citizens with undocumented parents (24.3%) compared to US citizens with lawfully present parents (17.8%). Immigration policy-related social exclusion and discrimination-mediated self/parental immigration status differences in SI. Although food insecurity did not differ by self/parental immigration status, greater food insecurity was associated with higher likelihood of SI. Greater campus belongingness was associated with a lower likelihood of endorsing SI for all students regardless of immigration status or legal vulnerability factors. Findings underscore the importance of examining self and parental immigration status as a social determinant of SI and the value of investigating aspects of legal vulnerability as explanatory factors.
