Background: Climate change and sustainability are highly interconnected. Addressing climate change requires major social change and collective action. The current study examined the prevalence of, and factors associated with, four climate change activism behaviors in a U.S. nationally representative sample. Methods: Data were derived from the Pew Research Center American Trends Panel conducted in April 2021 of 13,749 panelists. Key outcomes included (1) attending a protest or rally addressing climate change, (2) volunteering for a climate change activity, (3) donating money to an organization focused on climate change, and (4) contacting an elected official to urge them to address climate change. Multivariable logistic regression models examined the independent associations with psychosocial and demographic variables. Results: A fourth (24.7%) of participants reported engagement in one or more climate change activism behaviors. Of those who reported climate change activism, most (54.7%) only engaged in one activity. In the multivariable regression models, individual and social factors were significantly associated with all four climate action outcomes. Factors include social network communications and social norms variables, such as encouragement to take action, criticism for not taking action, and climate change communication frequency. Discussion: This study’s findings indicate that over 41 million U.S. adults reported having donated money to an organization focused on addressing climate change in the prior year, 25 million volunteered, and 26 million contacted an elected official. The association of social and communication variables with climate change activism suggests the importance of training people to talk about and encourage others to engage in climate change activism.

Background: Food insecurity is a growing public health concern associated with adverse cognitive outcomes and shaped by structural barriers. However, the psychosocial mechanisms linking food insecurity to cognitive difficulty remain underexplored. This study examined whether perceived discrimination and vigilance help explain this relationship and whether these pathways differ by U.S. nativity status. Methods: We used data from the 2023 National Health Interview Survey (NHIS) and analyzed 27,525 adults (23,000 U.S.-born and 4,525 foreign-born) aged 18 and older. Key variables included food insecurity, cognitive difficulty, perceived discrimination, and vigilance. We conducted moderated sequential mediation analyses, with discrimination and vigilance as mediators and nativity as a moderator. Models adjusted for age, sex, race/ethnicity, marital status, education, income, and self-rated health. Results: Food insecurity, discrimination, and vigilance were significantly associated with greater odds of cognitive difficulty. Among U.S.-born individuals, the sequential pathway from food insecurity through discrimination and vigilance was significant (β = 0.10, 95% CI: 0.08, 0.12), accounting for 52% of the total effect. Among foreign-born individuals, the pathway was also significant and fully mediated (β = 0.05, 95% CI: 0.03, 0.08), explaining 39% of the total effect. Nativity significantly moderated the full sequential pathway (β = -0.05, 95% CI: -0.07, -0.03), with stronger mediation observed among U.S.-born adults. Conclusions: Discrimination and vigilance help explain how food insecurity affects cognitive difficulty. Addressing both material hardship and psychosocial stress may help prevent cognitive decline across diverse populations.

Black women in the United States face intersecting challenges of HIV and intimate partner violence. Few programs integrate safety planning with HIV care engagement while addressing strengths and contextual factors that sustain resilience. We developed 1MoreStep, a strengths-based intervention grounded in a cognitive behavioral approach and an HIV stigma framework. Formative work included 12 in-depth interviews, seven focus groups, and a six-member Community Advisory Board. Findings revealed multilevel barriers, including internalized and anticipated stigma, isolation, and structural service gaps. These insights informed a six-session hybrid curriculum incorporating cognitive behavioral tools, peer support, scenario-based activities, and the myPlan app. Guided by participants' feedback, we iteratively refined materials to ensure cultural fit, clarity, fidelity, and flexibility. 1MoreStep targets the psychological, interpersonal, and structural challenges faced by Black women living with HIV who experience intimate partner violence. A randomized, pilot, clinical trial is underway to examine the feasibility, acceptability, and preliminary efficacy of the intervention.
