Exposure to ethnic discrimination has been conceptualized as a sociocultural stressor that is associated with lower self-rated health. However, this association remains understudied among Hispanics and less is known about constructs that may mitigate the effects of ethnic discrimination on self-rated health. Accordingly, this study aimed to (a) examine the association between ethnic discrimination and self-rated health among Hispanic emerging adults (ages 18-25), and (b) examine the extent to which self-esteem and resilience may moderate this association.

Addressing comorbidities contributing to cognitive impairment in people living with HIV (PLWH) remains imperative. Prior studies utilizing reaction time intra-individual variability (RT-IIV), a robust behavioral marker of cognitive dysfunction, demonstrate increased cognitive impairment in adults living with HIV who have high early life stress (ELS) exposure relative to those with low-ELS exposure. Yet, it is unknown whether RT-IIV elevations are due to high-ELS alone or both HIV-status and high-ELS.

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.

Data were drawn from a cross-sectional study of 200 Hispanic adults ages 18-25, recruited from two urban counties in Arizona and Florida.

Background: Diversion programs are considered alternatives to the arrest and incarceration of non-violent drug offenders, including those found in possession of smaller amounts of cannabis in states with prohibitive laws. Despite the progressive nature of such programs, the inability to complete diversion program requirements can often result in greater involvement with the criminal justice system than traditional case adjudication. Few studies have evaluated racial group differences in cannabis diversion program completion.

Emerging adulthood has been described as a difficult stage in life and may be particularly stressful for Hispanic emerging adults who are disproportionately exposed to adversity and chronic sociocultural stressors.

As such, this study aimed to (1) examine the association between resilience and depressive symptoms among Hispanic emerging adults, and (2) examine the extent to which intrapersonal resources (e.
