Emotion dysregulation and hazardous drinking in relation to suicidal ideation among Spanish-speaking Latinx daily-smokers

Objective: Suicidal ideation has increased among Latinx individuals in the last decade. Smoking increases the likelihood of suicidal ideation but work on Latinx smokers is minimal. Hazardous drinking and emotion dysregulation could be factors related to suicidal ideation among Latinx smokers, as has been evident in non-Latinx White samples. The current study sought to examine the main and interactive effects of emotion dysregulation and hazardous drinking in relation to suicidal ideation among Latinx daily-smokers. Methods: Participants were 371 Spanish-speaking daily-smokers (58.8% female; M_age = 33.3; SD_age = 9.8) recruited from the United States through Qualtrics. We used structural equation modeling (SEM) to test an interactive model of emotion dysregulation and hazardous alcohol consumption in relation to suicidal ideation; we also tested the effect of emotion dysregulation on suicidal ideation as a function of hazardous drinking status. Results: Results indicated that latent emotional dysregulation was associated with greater suicidal ideation (p < 0.001); however, hazardous drinking was not related to suicidal ideation (p = 0.186). The interactive term of emotional dysregulation and hazardous drinking was significantly related to suicidal ideation (p = 0.017). Specifically, greater emotion dysregulation was significantly related to suicidal ideation among Latinx smokers who engaged in hazardous drinking (p < 0.001) but not those who did not engage in hazardous drinking (p = 0.123). Conclusions: The current findings suggest that smoking combined with hazardous drinking may be related to increased suicidal ideation among Latinx smokers. Findings are discussed in relation to the potential role of intervention strategies that focus on emotion dysregulation and hazardous drinking among Latinx current daily smokers to mitigate suicidal risk among this established health disparities population.
