RESUMEN
Hispanic emerging adults are often exposed to ethnic discrimination, yet little is known about coping resources that may mitigate the effects of ethnic discrimination on psychological stress in this rapidly growing population. As such, this study aims to examine (1) the associations of ethnic discrimination, distress tolerance, and optimism with psychological stress and (2) the moderating effects of distress tolerance and optimism on the association between ethnic discrimination and psychological stress. Data were drawn from a cross-sectional study of 200 Hispanic adults ages 18-25, recruited from two urban counties in Arizona and Florida. Hierarchical multiple regression and moderation analyses were utilized to examine these associations and moderated effects. Findings indicated that higher optimism was associated with lower psychological stress. Conversely, higher ethnic discrimination was associated with higher psychological stress. Moderation analyses indicated that both distress tolerance and optimism moderated the association between ethnic discrimination and psychological stress. These study findings add to the limited literature on ethnic discrimination among Hispanic emerging adults and suggest that distress tolerance may be a key intrapersonal factor that can protect Hispanic emerging adults against the psychological stress often resulting from ethnic discrimination.
