Objective:
Social support may protect against Alzheimer’s disease and related dementias (ADRD), potentially through emotional or instrumental support elements. Black and Hispanic/Latinx older adults bear a disproportionate burden of ADRD. However, independent effects of emotional and instrumental support on cognition, a primary indicator of ADRD risk, are largely understudied in these groups. Guided by the differential vulnerability hypothesis – the theoretical framework which posits that systemic racism disadvantages Black and Hispanic/Latinx individuals’ health – we hypothesize that emotional and instrumental support may be particularly important to protect against worse cognition for Black and Hispanic/Latinx older adults, who often have fewer resources due to these inequalities (e.g., wealth, educational opportunities) to otherwise maintain health. Using the NIH Toolbox Emotion Module measures of emotional (e.g., the extent to which individuals can rely on others in challenging times) and instrumental support (e.g., the extent to which individuals can rely on others for assistance in daily activities), we aimed to identify positive social support factors (i.e., emotional and instrumental support) that may protect against ADRD risk (i.e., longitudinal executive function and memory performance) among Black and Hispanic/Latinx older adults.
Participants and Methods:Participants were 362 Black and 265 Hispanic/Latinx adults aged 65-89 (63% female, average age=75) from the Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) Study who completed baseline and up to two additional waves of assessments (every 1.5 years), including questionnaires, neuropsychological evaluations, and the NIH toolbox. Predictors included baseline covariates (i.e., age, language of test administration, gender, education, income, self-rated health) and NIH toolbox emotional and instrumental support variables. Outcomes were baseline and longitudinal memory (visual and verbal episodic memory) and executive functioning (verbal fluency and working memory) composites from the Spanish and English Neuropsychological Assessment Scales (SENAS). Latent growth curve models were conducted separately in Black and Hispanic/Latinx participants to estimate effects of emotional and instrumental support on baseline cognition and subsequent change in each domain.
Results:Black participants reported greater emotional support. There were no group differences in levels of instrumental support. Greater instrumental support was associated with better initial memory (standardized β= .194, 95%CI: [.063, .325]) among Black participants but not among Hispanic/Latinx participants. In Hispanic/Latinx participants, greater emotional support was associated with better initial executive functioning (standardized β= .215, 95%CI: [.079, .350]. Emotional support was not associated with either cognitive domain in Black participants. There were no associations between emotional or instrumental support on cognitive change in either group.
Conclusions:Results point to differences between Black and Hispanic/Latinx older adults in the impact of specific aspects of social support on different cognitive domains. Positive associations between instrumental support and baseline memory in Black participants and between emotional support and executive functioning in Hispanic/Latinx participants suggest unique cognitive consequences of social support across groups. Differences in the role of specific types of social supports may be useful in identifying intervention targets specifically for Black and Hispanic/Latinx older adults, who are disproportionately affected by ADRD. Future research will examine these constructs using multiple group models to test these associations more rigorously.

Objective:
Cardiovascular disease (CVD) is a well-known risk factor for cognitive impairment and dementia, particularly among minoritized groups that have experienced a history of low childhood socioeconomic status (SES). Although previous literature has linked all levels of SES to varying degrees of stress exposure, children raised in higher SES households have more access to resources and services that encourage optimal growth and development than children who grow up in lower SES households. Given the disproportionate burden of dementia and cognitive deficits within minoritized groups, the present study examined whether childhood SES is associated with later life cognition among Black and White older adults and if this association persists after accounting for hypertension, a possible mediator of the relationship between childhood SES.
Participants and Methods:1,184 participants were from the first wave of the STAR (n = 397 Black [Mage= 75.0 ±6.8 years]) and KHANDLE (386 Black [Mage= 76.2 ±7.2 years] and 401 White [Mage= 78.4 ±7.5 years]) cohorts. We used general linear models to examine the relationship between childhood SES and later-life executive function, semantic memory, and verbal memory scores, and midlife hypertension. Childhood SES was measured by self-reported perceived financial status (with participants given the following options: ‘pretty well off financially’, ‘about average’, ‘poor’, or ‘it varied’). These models were assessed in the full sample and also stratified by race.
Results:In the full sample, childhood financial status was not associated with semantic memory, verbal episodic memory, or executive function. Financial status was associated with semantic memory in Black adults (β = -.124, t(771) = -2.52, p = .01) and this association persisted after accounting for hypertension (β = -.124, t(770) = -2.53, p = .01). There was no association between childhood financial status and later life semantic memory among White adults. There was no association between childhood financial status and later life verbal episodic memory or executive function in either Black or White adults in models with or without adjustment for hypertension.
Conclusions:Our findings showed no relationship between childhood SES and cognition, except for semantic memory in Black participants; this relationship persisted after accounting for midlife CVD. Future analyses will assess both direct and indirect effects of more predictive measures of childhood SES on late-life cognition with midlife CVD as a mediator.

Background
Subthreshold depression (sD) negatively impacts well-being and psychosocial function and is more prevalent compared with major depressive disorder (MDD). However, as adults with sD are less likely to seek face-to-face intervention, internet-based cognitive-behavioral therapy (ICBT) may overcome barriers of accessibility to psychotherapy. Although several trials explored the efficacy of ICBT for sD, the results remain inconsistent. This study evaluated whether ICBT is effective in reducing depressive symptoms among Chinese adults with sD.
MethodsA randomized controlled trial was performed. The participants were randomly assigned to 5 weeks of ICBT, group-based face-to-face cognitive-behavioral therapy (CBT), or a waiting list (WL). Assessments were conducted at baseline, post-intervention and at a 6-month follow-up. The primary outcome measured depressive symptoms using the Center for Epidemiological Studies Depression Scale (CES-D). Outcomes were analyzed using a mixed-effects model to assess the effects of ICBT.
ResultsICBT participants reported greater reductions on all the outcomes compared to the WL group at post-intervention. The ICBT group showed larger improvement on the Patient Health Questionnaire-9 (PHQ-9) at post-intervention (d = 0.12) and at follow-up (d = 0.10), and with CES-D at post-intervention (d = 0.06), compared to the CBT group.
ConclusionsICBT is effective in reducing depressive symptoms among Chinese adults with sD, and improvements in outcomes were sustained at a 6-month follow-up. Considering the low rates of face-to-face psychotherapy, our findings highlight the considerable potential and implications for the Chinese government to promote the use of ICBT for sD in China.
