Assessing the Mental Model State of Emergency Responders in the Context of Radiological Dispersal Device (RDD) Incidents: A Multi-state Study.

ABSTRACT: Hazardous Materials (HAZMAT) Technicians' notions of mental model, or cognitive representations of their understanding and beliefs regarding Radiological Dispersal Devices (RDDs) incidents, have not been previously explored. A prior study developed an Expected Mental Model State (EMMS) framework specific to RDD incident response for HAZMAT technicians. The work herein presents the development of a derivative of this framework, the EMMS Diagnostic Matrix, to evaluate the actual Mental Model State (MMS) of HAZMAT technicians in the context of RDD incidents. The EMMS Diagnostic Matrix was administered via a survey and simulation activity in four U.S. states representing the Northeast, West, South, and Midwest regions. Data were collected and coded using grounded theory methodology. Reflexive thematic analysis was employed to identify themes across related areas where the notions of mental model for the HAZMAT technician responders' actual MMS differed from the EMMS. The analysis of the collected data revealed four significant themes representing incomplete notions of the mental model spanning various EMMS conceptual domains: Overestimation of Radiation Dose and Health Effects, indicating misunderstandings about the health impacts of radiation exposure, Acute Radiation Syndrome (ARS), particularly in the lower range of radiation doses; Overreliance on Responder Protection [personal protective equipment (PPE)/self-contained breathing apparatus (SCBA)], highlighting gaps in understanding radiation principles and radioactive material dispersal properties from a radiological dispersal device; Misunderstanding Radiation Detection and Units, signifying confusion about radiation units and differentiation between dose rate and accumulated dose; and Incomplete Understanding of Radiation Characteristics and Dispersal Properties, outlining a limited grasp of inhalation risks from radiation and the dispersal traits of a radiological dispersal device. The interconnectedness of these technical misunderstandings can guide the development of a strategic plan to evaluate and modify existing training, aiming at these specific themes to improve the efficiency of HAZMAT technicians in emergency situations and to identify areas for further research.

Sexual minority identifiers and their perception of illicit drug use risks in the US: Results from a National Survey.

PURPOSE: This study examined the relationship between sexual identities and perception of risks associated with illicit drug use among a nationally representative sample of US adults. METHODS: We analyzed data from five waves of the National Survey on Drug Use and Health (NSDUH, 2015-2019), with 205,418 adult participants. Six survey questions assessing participants' perceptions of the risks associated with illicit drug use (LSD, heroin, and cocaine) were subjected to principal component analysis. Sex-stratified ordered logistic regressions were used to explore potential disparities in perceptions regarding the risk associated with illicit drug use among sexual minority identifiers. RESULTS: Among male participants, approximately 11.3% and 1.8% of them perceived illicit drug use as moderate and low risks, respectively. About 6.0% of female participants perceived illicit drug use as moderate risk, and 1.1% of female participants perceived it as low risk. The sex-stratified regression models demonstrated that participants who identified as lesbian/gay or bisexual all had higher odds of reporting low perception of illicit drug use risks as compared to their heterosexual counterparts (all p < 0.01). CONCLUSIONS: Illicit drug use prevention strategies should consider risk perception disparities by sexual minority populations.

Ageism webinars: a needs-based continuing education training for the national aging network.

To combat ageism, the National Resource Center on Nutrition and Aging (NRCNA) launched two Ageism Webinars (AWs). The study's aims were to 1) assess the effectiveness of the AWs for increasing participants' perceived familiarity (FAM) and knowledge (KNOW) and producing high behavioral intent to implement recommended action steps and quality among participants, and 2) practice equitable evaluation by ascertaining whether outcomes were fairly achieved by participants regardless of race, age, and education. A convenience sample of mostly educated non-Hispanic females with an average age of 52 years (n = 193) completed a retrospective online survey post-webinar. A retrospective Likert scale noted an overall increase in perceived FAM and KNOW (p < 0.001). However, these changes were significantly smaller (p < 0.05) among those from historically marginalized races and ethnicities. The theory of planned behavior (TPB) items predicted high intention to complete the recommended action step following the webinars. High satisfaction for webinars was reported, with 98.7% wanting to attend future NRCNA training. This study provides evidence of an effective training modality for addressing ageist perspectives, and the demonstrated differences provide insight into how to improve the AWs and the evaluation of future webinars.

Racial/ethnic/gender-Based Differences in Health Trajectories Among American Older Adults: 10-Year Longitudinal Evidence from the Health and Retirement Study.

Health disparity by race/ethnicity or gender has been well-documented. However, few researchers have examined health outcomes based on the intersection of individuals' race, ethnicity, and gender or investigated various health dimensions. Guided by an intersectionality framework, this study explores racial/ethnic/gender-based differences in trajectories of multiple health outcomes over a ten-year period among American older adults. Longitudinal data from the Health and Retirement Study (2004-2014) were used (N = 16,654). Older adults (65+) were stratified into six mutually-exclusive groups based on their race, ethnicity, and gender: Non-Hispanic (NH) White Men, NH White Women, NH Black Men, NH Black Women, Hispanic Men, and Hispanic Women. Growth curve models examined the trajectories of three health measures, including cognitive function, physical function limitations (i.e. activities of daily living and instrumental activities of daily living), and depressive symptoms. NH White men and women reported significantly better outcomes in cognition and physical function trajectories than racial/ethnic minority groups. Women in all racial/ethnic groups had more depressive symptoms but better cognition than men. Hispanic women reported the most depressive symptoms. Hispanic women and NH Black women had the worst physical function limitations. NH Black men/women were the most disadvantaged in cognition. Racial/ethnic/gender-based differences were stable over time in all health trajectories. Study findings highlight the utility of an intersectional framework in understanding how multiple social identities intersect to generate protective and/or risk effects on cognitive, mental, and physical health. Multilevel intervention strategies are warranted to reduce the persistent health inequity gap.

Who Cares for Older Adults? A Cross-National Study of Care Sources for Older Adults With Functional Limitations and Associated Determinants.

The study compared care source typologies for older adults in China and the United States. Data from the 2014 U.S. Health and Retirement Study and the 2013 China Health and Retirement Longitudinal Study were used. The respondents included community-dwelling older adults aged 65 years or older with at least one limitation in activities of daily living (ADLs) or instrumental ADLs (IADLs) (NChina = 2476, NUS = 2898). Respondents reported whether they received assistance from spouse, child/grandchild, relatives, others, and formal helpers. Latent class analysis and multinomial logistic regression were applied. Four classes were identified in China and the U.S, separately. In both countries, ADLs and IADLs were strong determinants of care source typologies. Care sources were more diverse and included formal assistance among older Americans. Older Chinese relied largely on their spouses and children/grandchildren for support. Policy efforts are needed to expand formal long-term services and supports, particularly in China.

Insomnia Symptom Trajectory of Spouse Caregivers of Older Adults with Functional Limitations.

OBJECTIVES: This study examined the long-term impact of spouse caregiving on insomnia symptoms, compared to propensity-score matched non-caregivers. METHODS: Health and Retirement Study data between 2006 and 2018 were used. Caregivers (n = 403) were respondents (aged 50+) who assisted their heterosexual spouses in performing (instrumental) activities of daily living at baseline. Non-caregivers were matched using a propensity score matching procedure based on baseline characteristics. Insomnia symptoms were measured every 4 years for both groups. Poisson mixed-effect models estimated the association between caregiver status and insomnia symptoms. RESULTS: Compared to matched non-caregivers, caregivers had similar severity of insomnia symptoms at baseline (ßcaregiver = 0.018, 95% CI = -0.089, 0.124) and reported a similar yearly change rate (ßcaregiver×time = -0.008, 95% CI = -0.017, 0.001). No moderation effects of care-recipients' dementia status and social support were significant. CONCLUSIONS: In this study sample, there is no evidence that spouse caregivers, specifically those who performed light duties, experience more severe insomnia symptoms than non-caregivers. CLINICAL IMPLICATIONS: Spouse caregiving, especially in a light-duty capacity, may not be detrimental to the caregivers' sleep health. More data are needed regarding insomnia in spouse caregivers with heavy duties of care to fully assess the health impact of the caregiving experience.

Examining the Association between Medical Marijuana Legalization and Criminal Behaviors: Evidence from a U.S. Representative Sample.

Background: Medical marijuana legalization (MML) has been widely implemented in the past decade. However, the debates regarding the consequences of MML persist, especially criminal behaviors. Objectives: We examined the association between MML and criminal behaviors among adults in the United States. The criminal behaviors measured three past-year offenses: whether the adult (1) have sold illegal drugs, (2) have stolen anything worth > $50 USD, or (3) have attacked someone. Methods: Using the 2015-2020 National Survey of Drug Use and Health, we included 214,505 adults in our primary analysis for 2015-2019 and 27,170 adults in 2020 for supplemental analysis (age > = 18). Weighted multivariable logistic regression models were used to examine the association between MML and three criminal behaviors. Results: In our primary analysis, we observed no statistically significant association between MML and the three outcomes of criminal behavior. Nevertheless, our supplemental analysis of the 2020 data showed MML was associated with increasing odds of the three criminal behaviors (have sold illegal drugs: AOR [adjusted odds ratio] = 1.7; have stolen anything worth > $50 USD: AOR = 1.9; have attacked someone: AOR = 1.8; all p < 0.05). Conclusion: Surveys from 2015 to 2019 did not suggest MML as a risk factor for higher incidence of criminal behaviors. However, 2020 data showed statistically significant association between MML and selected criminal behaviors. Issues related to the COVID-19 pandemic, such as the U.S. economic downturn, could potentially explain this discrepancy. Further research efforts may be warranted.

Understanding Healthcare Providers' Care for Patients with Medications Treating Opioid Use Disorder in the Emergency Department: A Scoping Review.

BACKGROUND: There is limited research exploring the changing clinical practices among healthcare providers (HPs) care for patients with Emergency Department (ED)-initiated Medication for Opioid Use Disorder (MOUD). METHODS: This scoping review followed the methodological framework of Arksey and O'Malley to map relevant evidence and synthesize the findings. We searched PubMed, EMBASE, CINAHL, Web of Science, and Scopus for related studies from inception through October 12, 2022. Following the application of inclusion and exclusion criteria, 16 studies were included. Subsequently, they were charted and analyzed thematically based on ecological systems theory. RESULTS: The main determinants in the four ecological systems were generated as follows: (1) microsystem: willingness and attitude, professional competence, readiness, and preference; (2) mesosystem: ED clinical practices, departmental factors; (3) exosystem: multidisciplinary approaches, discharge planning, and (4) macrosystem: stigma, health insurance, policy. The findings have implications for HPs and researchers, as insufficient adoption, implementation, and retention of MOUD in the ED affect clinical practices. CONCLUSIONS: Across the four ecological systems, ED-initiated MOUD is shaped by multifaceted determinants. The microsystem underscores pivotal patient-HP trust dynamics, while the mesosystem emphasizes interdepartmental synergies. Exosystemically, resource allocation and standardized training remain paramount. The macrosystem reveals profound effects of stigma, insurance disparities, and evolving policies on treatment access and efficacy. Addressing these interconnected barriers is crucial for optimizing patient outcomes in the context of MOUD.

Racial and Ethnic Disparities and Prevalence in Prescription Drug Misuse, Illicit Drug Use, and Combination of Both Behaviors in the United States.

This study examines racial and ethnic disparities and prevalence in prescription drug misuse, illicit drug use, and the combination of both behaviors in the United States. Using five waves of the National Survey on Drug Use and Health (NSDUH, 2015-2019; n = 276,884), a multinomial logistic regression model estimated the outcomes of prescription drug misuse, illicit drug use, and the combination of both behaviors. Participants' age was considered as an interaction effect. Approximately 5.4%, 2.9%, and 2.5% misused prescription drug, used illicit drug, or had both behaviors, respectively. Compared with White participants, Black (AOR = 0.69, 99.9 CI: 0.61, 0.79) and Asian (AOR = 0.60, 99.9% CI: 0.42, 0.87) participants had significantly lower odds of reporting prescription drug misuse. Individuals who were classified as others had higher odds of reporting illicit drug use (AOR = 1.31; 99.9% CI: 1.05, 1.64), compared with White participants. Black (AOR = 0.40, 99.9% CI: 0.29, 0.56) and Hispanic (AOR = 0.71, 99.9% CI: 0.55, 0.91) participants were significantly less likely to have both prescription drug misuse and illicit drug use behaviors. Interaction analysis showed that Black participants between 18 and 49 years old were less likely to participate in prescription drug misuse. However, Black participants who were 50 years of age or above were more likely to engage in illicit drug use and the combination of both prescription drug misuse and illicit drug use (all p < 0.001). Hispanic adult participants between 18 and 49 years old were more likely to engage in illicit drug use. Successful intervention and cessation programs may consider the cultural and age disparities among different racial and ethnic groups.

Middle Age and Older Adults: Their Nutrition and Physical Activity Needs and How Best to Address Them.

This cross-sectional study assessed the nutrition and physical activity (PA) needs, practices, and programming preferences of adults ages 40+ years from seven states (n = 1,250). Respondents were mostly educated, White, food-secure, adults ages 60+ years. Many were married, suburban-residing, and interested in health programming. By self-report most respondents were "at nutritional risk" (59.3%), in "somewhat good health" (32.3%), and sedentary (49.2%). One-third reported PA intention in the next two months. Desired programs were less than four weeks and under 4 h weekly. Respondents preferred to attend self-directed online lessons (41.2%). Program format preference varied by age (P < 0.05). More respondents aged 40-49 years and 70+ years reported a preference for online group sessions compared to those aged 50 to 69 years. Respondents ages 60 to 69 years reported the highest preference for interactive apps. More older respondents (60 years and older) preferred asynchronous online lessons compared to the younger respondents (age 59 years and younger). There were significant program participation interest differences by age, race, and location (P< 0.05). These results revealed a need and preference for self-directed, online health programming for middle-aged and older adults.

Health Behavior Patterns and Associated Risk of Memory-Related Disorders Among Middle-Aged and Older Chinese Couples.

Objectives: Studies on the interdependence of couples' health behaviors and subsequent cognitive outcomes remain limited. Methods: Longitudinal data from the China Health and Retirement Longitudinal Study (2011-2018) were used (N = 1869 heterosexual couples). Latent class analysis identified the dyadic pattern of health behaviors in 2011 (i.e., alcohol consumption, smoking, and physical inactivity). Stratified Cox models examined the association of latent classes with risk of developing memory-related disorders in 2013-2018. Results: Three classes were identified: class 1 (21.25%, only husband smoke, and both active), class 2 (47.55%, both inactive, neither drink nor smoke), and class 3 (31.20%, both drink and smoke, and both active). Couples' sedentary lifestyle was associated with an increased risk of memory-related disorders among both husbands and wives. Conclusion: Couples were moderately concordant in their physical activity but weakly in smoking and drinking. Couple-based interventions, especially promoting physical activity, may reduce cognitive aging among middle-aged and older Chinese couples.

Racial Differences in Employment and Poverty Histories and Health in Older Age.

INTRODUCTION: Black Americans encounter more barriers in the job market and earn less than White Americans. However, the extent to which racial disparities in employment and poverty histories impact health is not fully understood. This study characterized employment‒poverty histories for Black and White middle-aged adults and examined their association with health. METHODS: Respondents born in 1948-1953 and enrolled in the 2004 Health and Retirement Study (NBlack=555, NWhite=2,209) were included. Sequence analysis grouped respondents with similar employment‒poverty trajectories from 2004 to 2016, and confounder-adjusted regression analyses estimated the associations between these trajectories and health in 2018. Analyses were conducted in 2021-2022. RESULTS: More than 23% of Black respondents experienced both employment and poverty fluctuations, including bouts of extreme poverty (<50% of the federal poverty threshold), whereas no trajectory for White respondents included extreme poverty. Adversities in employment‒poverty were associated with worse health. For example, among Black respondents, those who experienced both employment and poverty fluctuations had worse cognition than those employed and not poor (ß= -0.55 standardized units, 95% CI= -0.81, -0.30). Similarly, among White respondents, those who experienced employment fluctuations had worse cognition than those employed (ß= -0.35, 95% CI= -0.46, -0.24). Notably, the employed and not poor trajectory was associated with worse survival among Black respondents than among White respondents. CONCLUSIONS: Employment fluctuations were associated with worse health, especially cognitive function, where the association was stronger among Black Americans who experienced both employment fluctuations and poverty. Findings highlight the importance of enhancing employment stability and of antipoverty programs, especially for Black Americans.

Cognitive appraisals and coping strategies of registered nurses in the emergency department combating COVID-19: A scoping review.

OBJECTIVE: Explore the relevant evidence about stress-related cognitive appraisal and coping strategies among registered nurses in the emergency department (EDRNs) coping with the COVID-19 pandemic. METHODS: This scoping review followed the methodological framework of Arksey and O'Malley to map relevant evidence and synthesize the findings. We searched PubMed, EMBASE, CINAHL, Web of Science, and Scopus electronic databases for related studies from inception through February 2, 2022. This review further conducted study selection based on the PRISMA flow diagram and applied Lazarus and Folkman's Psychological Stress and Coping Theory to systematically organize, summarize, and report the findings. FINDINGS: Sixteen studies were included for synthesis. Most of the studies showed that the majority of EDRNs were overwhelmed by the COVID-19 pandemic. Depression, triaging distress, physical exhaustion, and intention to leave ED nursing were cited as major threats to their wellness. Additionally, comprehensive training, a modified triage system, a safe workplace, psychological support, promotion of resilience, and accepting responsibility may help EDRNs cope with pandemic-related challenges effectively. CONCLUSION: The long-lasting pandemic has affected the physical and mental health of EDRNs because they have increased their effort to respond to the outbreak with dynamically adjusted strategies. Future research should address a modified triage system, prolonged psychological issues, emergency healthcare quality, and solutions facing EDRNs during the COVID-19 or related future pandemics. CLINICAL RELEVANCE: EDRNs have experienced physical and psychological challenges during the pandemic. The ED administrators need to take action to ensure EDRNs' safety in the workplace, an up-to-date triage system, and mental health of frontline nurses to provide high-quality emergency care for combating COVID-19.

Depressive Symptom Trajectories and Cognition Among Older American Couples: A Dyadic Perspective.

OBJECTIVES: This study examined whether trajectories of depressive symptoms of one spouse are associated with the other spouse's memory. METHODS: Longitudinal data from the Health and Retirement Study (2004-2016) were used (N = 5690 heterosexual couples). Latent-class growth analysis and structural equation models examined the actor and partner effects of depressive symptom trajectories on memory. RESULTS: Four depressive symptom trajectories were identified (i.e., persistently low, increasing, decreasing, and persistently high). Compared to the low trajectory group, the increasing and persistently high trajectories were associated with worse memory for both men and women. While none of the wives' depressive symptom trajectories was significantly associated with husbands' memory (p > .05), husbands' decreasing trajectory was linked to wives' better memory (ß = 0.498, 95% CI = 0.106, 0.890). DISCUSSION: Older adults with increasing and persistently high depressive symptoms may experience worse memory. Psychosocial interventions targeting depressive symptoms among older men may be beneficial to their spouses' memory.

Food Insecurity and Mental Health Trajectories during the COVID-19 Pandemic: Longitudinal Evidence from a Nationally Representative Survey.

Food insecurity and mental disorders are pressing public health issues during COVID-19. Empirical evidence on the extent to which food insecurity affects mental health outcomes of American adults as the pandemic unfolds remains limited. Longitudinal data from the Understanding Coronavirus in America survey collected biweekly between April and December 2020 were used (N=4,068). Respondents were asked about their food insecurity experiences and stress, anxiety, and depressive symptoms. Linear mixed-effect models were estimated. Food insecurity was associated with higher levels of stress, anxiety, and depressive symptoms. Stress, anxiety, and depressive symptoms declined among food-secure U.S adults. However, mental health trajectories of respondents with various food insecurity categories remained stable or worsened over time. The mental health gap between food-secure and food-insecure groups widened over time. Food insecurity has substantial mental health implications amidst the pandemic. Screening for and addressing food insecurity may alleviate the mental health burden borne by food-insecure people.

Patterns of Outpatient Service Satisfaction among Low-Income Adults in Rural China: A Latent Class Analysis.

(1) Background: Low-income rural residents in China are disadvantaged due to their financial vulnerability and insufficient access to resources, and this situation demands more research effort. This study examined the pattern of outpatient service satisfaction and its determinants among low-income adults in rural China. (2) Methods: Rural low-income respondents who used outpatient services in their local healthcare facilities in Jiangsu, China evaluated the access, cost, environment, doctor-patient interaction, and other topics during their outpatient visit (N = 662). Latent class analysis was used to identify the groups characterized by various dimensions of outpatient satisfaction. Multinomial logistic regression explored the determinants of class membership. (3) Results: Three latent classes were identified: 28.70% had low satisfaction, unsatisfied with every dimension; 20.69% reported medium satisfaction that valued doctor-patient relationships; and 50.60% had high satisfaction but thought that costs were high. Both low and medium satisfaction were associated with a higher proportion of self-paid fees. (4) Conclusions: Healthcare costs were an important determinant of outpatient service satisfaction. Medical social workers are suggested to be included in the medical team to help patients identify financial assistance. Special aid programs may be developed to help relieve rural low-income patients' medical cost-related burden.

Development of a Nutrition Environment Assessment Tool for Latino Ethnic Stores.

The objectives were to: (1) adapt the Nutrition Environment Measures Survey for Stores (NEMS-S) to better culturally fit small Latino grocery stores (tiendas) in Iowa; (2) assess the newly adapted Latino NEMS-S for inter-rater and test-retest reliability; and (3) compare Latino and original NEMS-S summary scores. This pilot instrument, containing culturally appropriate foods from the original NEMS-S and 2015 US Dietary Guidelines for Americans, underwent two rounds of formative evaluation. The new instrument and scoring protocol were applied to a random sample of 42 of 81 possible tiendas in Iowa. Cohen's kappa was used to assess inter-rater and test-retest reliability for availability and quality of indicator food items (total scores and food category sub scores). There were no differences in summary scores for inter-rater or test-retest reliability using paired t-tests. Inter-rater agreement was high (range 0.82-1.00; p < 0.001). Tiendas averaged 42.0 ± 7.5 of 57 possible points on the Latino NEMS-S, but only 12.0 ± 4.6 of 54 points on the original NEMS-S (p < 0.001). The Latino NEMS-S is a reliable tool for assessing the food environment within Iowa tiendas. Culturally specific instruments can describe diverse food environments more accurately and guide public health nutrition interventions within communities.

Kinship bereavement and psychological well-being of U.S. Chinese older women and men.

This study examined the relationship of kinship bereavement with the psychological well-being of Chinese American older women and men. Data from the Population Study of ChINese Elderly were used. Respondents were asked if their spouse, children/grandchildren, siblings, close relatives, and friends had died. Widowhood was associated with more loneliness for both genders. For women, close relative/friend loss was associated with more stress, and children/grandchildren loss was linked to stronger anxiety. Only coefficients for close relative in the stress model were significantly different between genders. The variation in patterns of kinship bereavement may be attributed to Chinese cultural attitudes toward death.

Gender-based depression trajectories following heart disease onset: significant predictors and health outcomes.

BACKGROUND: Using a nationally representative sample of U.S. older adults (50+), this study investigates gender-based depression trajectories following heart disease onset and associated risk of disability and mortality over an 8-year period. METHOD: Six waves of longitudinal data from the Health and Retirement Study (2006-2016) were used (n = 1787). Heart disease onset was defined as self-reporting no heart disease at baseline but reporting a positive diagnosis in a subsequent wave. Growth Mixture Modelling identified depression trajectories. Multinomial logistic regression models determined significant predictors of depression trajectories. Cox proportional-hazards models examined the associated disability and mortality risks. RESULTS: Three distinct depression trajectories were identified, including persistent minimal depression (men: 68.65%; women: 60.17%), moderate depression (women: 29.70%; men: 17.97%), and chronic depression (women: 10.12%) or emerging depression (men: 13.38%). Younger age and depression status at baseline were associated with women's chronic depression and men's emerging depression. Chronic/emerging and moderate depression were associated with higher disability risks than was minimal depression among both women and men (hazard ratios [HR] ranged from 2.12 to 3.92, p < 0.001). Only men's emerging depression was linked to higher mortality risk compared to minimal depression (HR = 2.03, p < 0.001). CONCLUSION: Longitudinal course of depression following onset of heart disease is heterogeneous in later life. Unfavorable depression trajectories (i.e. moderate, chronic, and emerging) were associated with higher disability risk compared to the minimal depression trajectory. Study findings characterize risk stratification regarding depression after heart disease onset, which can inform the development of interventions to improve health outcomes among older adults with heart conditions.

Advance Directive Completion Among Older American Couples: A Dyadic Perspective on the Role of Cognitive Function and Other Factors.

OBJECTIVE: Dyadic perspective is scarce in existing advance directive (AD) literature. Particularly, the significance of one's own and/or one's partner's cognitive function on AD remains unknown. This study investigates the relationship of cognitive function and other factors with AD completion within the spousal context. METHOD: Data from the Health and Retirement Study (2014-2015) were used. Older heterosexual couples (age ≥65) married for 10+ years were asked if they had a living will and/or appointed a durable power of attorney for health care (DPAHC). Structural equation models examined the actor and partner effects of sociodemographic, health, and couple-level characteristics on wife's and husband's AD, respectively. RESULTS: Moderate spousal interdependence was observed in living will (kappa coefficient, κ = .60) and DPAHC (κ = .53). Older age and higher education were related to both spouses having AD. Less household wealth and being racial/ethnic minority were associated with a lower probability of having AD. Notable gender contrasts in actor and partner effects were found. Wife's higher level of cognitive function was associated with husband's AD completion. Contrarily, husband's lower level of cognitive function was associated with wife's AD completion. Retirement status had primarily actor effects for both husbands and wives. More chronic conditions were linked to husband's AD completion. DISCUSSION: The spousal interdependence of AD warrants practitioner efforts to facilitate family-oriented end-of-life planning. Wives and husbands may have different thoughts regarding their spouse's cognitive capacity to surrogate. Facilitating couple-based discussions may be a feasible approach to promote engagement with AD among older adults.
