Protocol for a telephonic mixed methods study to understand needs and find solutions for bereaved dementia caregivers.

INTRODUCTION: Most caregivers of people living with dementia will experience bereavement within 10 years, but study of and support for their needs rarely persists following the death of their care recipients. A single model that leverages theoretical insights as well as observation from lived experience might help identify who will have greater difficulty following dementia-related bereavement and suggest core mechanisms to target to relieve clinical and subclinical consequences. The millions of existing bereaved dementia caregivers likely have considerable insight into ways to improve experience. Rather than creating interventions from scratch, researchers might leverage those insights to more rapidly improve the lives of bereaved dementia caregivers. METHODS AND ANALYSIS: This study uses a transformative mixed methods approach to explore the needs of caregivers for individuals with Alzheimer's disease (AD) and AD-related dementias, incorporating both quantitative surveys (n=400) and qualitative semistructured interviews (n=45) across diverse subgroups. The study described in this protocol aims to quantitatively test a new model based on self-determination theory to help understand when and why bereaved dementia caregivers experience better and worse outcomes following bereavement. The study also aims to qualitatively explore the ways that bereaved dementia caregivers might meet their needs to inform future interventions. ETHICS AND DISSEMINATION: The study adheres to institutional guidelines, ensuring participant consent and minimising risks through verbal consent procedures and the removal of personal identifiers from survey responses. The study team will share findings widely through academic publications, conferences and targeted outreach to advocacy groups and healthcare professionals, while also providing concise summaries of results to participants and making them accessible through the lab's website.

Self-administered mindfulness interventions reduce stress in a large, randomized controlled multi-site study.

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ ; retrospective registration at ClinicalTrials.gov NCT06308744 ) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single, standalone mindfulness exercises effectively reduced stress, using Bayesian mixed-effects models. All exercises proved to be more efficacious than the active control. We observed a mean difference of 0.27 (d = -0.56; 95% confidence interval, -0.43 to -0.69) between the control condition (M = 1.95, s.d. = 0.50) and the condition with the largest stress reduction (body scan: M = 1.68, s.d. = 0.46). Our findings suggest that mindfulness may be beneficial for reducing self-reported short-term stress for English speakers from higher-income countries.

Racial/Ethnic Differences in the Predictive Utility of Psychosocial Determinants of COVID-19 Vaccination Intentions.

PURPOSE: To test whether the impact of subjective norms, race/ethnicity-specific descriptive norms, vaccine conspiracy beliefs, and prosocial concern on COVID-19 vaccination intentions differs by race/ethnicity for young adults. DESIGN: Cross-sectional study. SETTING: May-August 2021 in Texas. SUBJECTS: Racially/ethnically diverse unvaccinated college students (N = 314). MEASURES: COVID-19 vaccination intentions, theory-driven constructs (eg, perceived susceptibility), vaccine conspiracy beliefs, prosocial concern, and social norms. ANALYSIS: Block-sequential multiple Tobit regression. RESULTS: Results revealed three significant two-way interactions between race/ethnicity and (1) subjective norms, F (5, 251) = 2.28, P < .05; (2) COVID-19 vaccine conspiracy beliefs, F (5, 251) = 2.88, P < .05; and (3) prosocial concern, F (5, 251) = 2.61, P < .05. There was a positive association between subjective norms and intentions for European and African Americans, a positive association between prosocial concerns and intentions for European and multiracial/multiethnic Americans, and a negative association between conspiracy beliefs and intention for Hispanics. The interaction between race/ethnicity and race/ethnicity-specific descriptive norms was not significant, F (5, 251) = 1.09, P = .37. CONCLUSION: Although based on a relatively small sample, our findings suggest the importance of culturally tailoring COVID-19 vaccination messages to correct conspiracy beliefs, signaling a positive subjective norm, and enhancing prosocial concerns for specific racial-ethnic groups.

Risk Factors of Female-Perpetrated Intimate Partner Violence among Hispanic Young Adults: Attachment Style, Emotional Dysregulation, and Negative Childhood Experiences.

This paper examined whether risk factors commonly associated with intimate partner violence (IPV) are associated with female-perpetrated physical IPV and female physical IPV victimization among young Hispanic women. It also examined how emotion dysregulation, impulsivity, and attachment style exacerbated these relationships. Furthermore, it investigates how these associations differ by the type of self-reported physical violence against their romantic partner. Based on the participants' self-reported physical violence, they were classified into one of four groups: nonviolent, victim-only, perpetrator-only, and bidirectionally violent. Bidirectional violence was by far the most common form of violence reported. Utilizing self-report data from 360 young Hispanic women, we used binary logistic regression to examine potential predictors of physical IPV perpetration and victimization for each group. Results demonstrated that women in the bidirectionally violent group reported the highest levels of perpetration and victimization. Parental violence victimization, witnessing interparental violence, insecure attachment styles, and emotional dysregulation predicted physical IPV perpetration and victimization. These findings emphasize the need for effective interventions that include both members of the dyad and acknowledge the impact of women's attachment style, emotion dysregulation, and adverse childhood experiences on female-perpetrated IPV and female IPV victimization.
