Evaluating the role of smoking abstinence expectancies in the relation between perceived ethnic discrimination and cigarette dependence among Latinx individuals who smoke.

The experience of perceived ethnic discrimination is prevalent and has harmful effects across various behavioral health processes among Latinx persons. Yet, there is limited work on the association between perceived ethnic discrimination and smoking among this health disparities group. Building from initial work that has demonstrated a relationship between perceived ethnic discrimination and smoking abstinence expectancies, the present study sought to explore mechanisms by which perceived ethnic discrimination may be related to cigarette dependence. Specifically, we tested the indirect effect of perceived ethnic discrimination on cigarette dependence through smoking abstinence expectancies (i.e., negative mood, somatic symptoms, harmful consequences, and positive consequences) among Latinx persons who smoke (N = 338; M = 35.53 years; SD = 8.65; age range 18-61; 37.3% female). Results indicated that abstinence expectancies related to harmful consequences was a statistically significant underlying factor between the experience of perceived discrimination and cigarette dependence (b = 0.39, SE = 0.16, CI95% = 0.08, 0.71, CSE = 0.14). Overall, the present study suggests that smoking abstinence expectancies pertaining to harmful consequences may be a point of intervention for Latinx persons seeking to reduce or quit smoking. Future research is needed to extend the generalizability of these findings by corroborating the mediational role of abstinence expectancies related to harmful consequences across Latinx persons of varying cigarette use severity levels over time.
