ABSTRACT
Increasingly, dementia caregiver interventions are informed by acceptance-based approaches such as Acceptance and Commitment Therapy. These interventions promote psychological skills like psychological flexibility and value-based living. Less is known how these constructs interact within well-established caregiver stress processes. We examined a moderated mediation model (N = 161 dementia caregivers; PROCESS Procedure; SPSS Release 4.1), with BPSD frequency (Revised Memory and Behavior Problems Checklist) predicting depressive symptoms (10-item CES-D), mediated via caregiver burden (short Burden inventory). The moderator was the Values Questionnaire, and we controlled for gender, caregiver duration, age, income, and education. Results: revealed that the indirect effect of BPSD on depressive symptoms through caregiver burden was weakened through higher progress toward values (moderated mediation significant at p < .05). Committed action toward values signify caregivers' success at balancing care-related stress with other priorities. Interventions that build skills in values-based living have promise for caregivers, offering healthier ways to adjust to being a caregiver.
ABSTRACT
Objective: To assess possible moderating variables that influence the effectiveness of a college-based mental health literacy curriculum, Mental Health Awareness and Advocacy (MHAA). Participants: Students at a Western University in the United States (MHAA treatment group: N = 474; Comparison group: N = 575). Methods: Using a non-randomized, quasi-experimental design over six semesters (2017-2019), students in the treatment and control groups reported on key demographic factors, experiences with mental health, and their knowledge, self-efficacy, and behaviors related to mental health literacy in a pretest/post-test format. Linear mixed effects models were used to assess moderation. Results: MHAA curriculum's efficacy varied based on participants' current depression and anxiety levels, whether they had prior personal experience with a mental health concern, whether they had been diagnosed with a mental health concern, and whether they had experienced suicidal thoughts. Conclusions: Reducing anxiety and depression among students may increase the efficacy of the MHAA program.
ABSTRACT
Complaints represent an important metric for assessing the quality of nursing home (NH) care. Using the Automated Survey Processing Environment (ASPEN) Complaints/Incidents Tracking System dataset (2017), we examined the relationships between zero-deficiency complaints (ZDCs) and zero-deficiency substantiated complaints (ZDSCs) and the proportion of residents with dementia. NHs (N = 15,339) were separated into three groups-proportion of residents with dementia in the top, two middle, and the bottom quartiles. Negative binomial regressions assessed zero-deficiency complaint patterns in relation to NHs' proportion of residents with dementia, controlling for facility characteristics, staffing, and racial pattern. We reported average marginal effects (AMEs) and 95% confidence intervals (CIs). NHs in the top quartile yielded higher numbers of both ZDC (AME = .189, 95% CI: .102-.276, p < .001) and ZDSC (AME = .236, 95% CI: .094-.378, p = .001), than NHs in the bottom quartile. Results suggest a need for more uniform investigation processes and staff training to promote a more valid complaint process for residents with dementia.

AIM: To examine the mental health conditions of family caregivers residing away from their loved ones who experienced visitation restrictions during the coronavirus disease 2019 pandemic. DESIGN: A mixed-methods design applying the Kessler Scale-10 for the quantitative measurement of psychological distress and an open-ended question for qualitative analysis. METHODS: The participants were recruited from care facilities between February and September 2021. This cross-sectional study included 197 family caregivers who were utilizing formal residential care services for their loved ones. Using thematic analyses, open-ended responses regarding the impact of visitation restrictions were coded. These themes were then examined to determine thematic patterns across caregiver characteristics. RESULTS: Thirteen themes were identified regarding the impact of visitation restrictions. Many participants reported primary harmful effects as follows: 'inability to confirm the type of care and lifestyle assistance provided to an older relative' and 'difficulty communicating with an older relative because of the inability to converse face-to-face'. Younger age, being employed, poor sleep, poor relationship quality with the care recipient and experiencing harmful effects from the visitation restrictions were associated with psychological distress. CONCLUSION: Our findings suggest that to maintain positive mental health after a care transition, it is important for family caregivers to take part in the care of their loved ones and ensure information sharing between the care recipient's family and institution. IMPACT: These findings suggest that both residents and family caregivers living outside facilities may feel distressed due to separation. Therefore, institutional care staff needs to consider how to adjust facility procedures or communication with family caregivers. PATIENT OR PUBLIC CONTRIBUTION: The comments obtained from the participants in this survey helped to shape the study design and are expected to contribute to the further development of quality facility care.

Objectives: Nursing home (NH) residents' capacity to communicate deteriorates with dementia. Consequently, NHs with high proportions of people living with dementia (PLWD) may receive fewer resident complaints, and/or investigating complaints may be challenging. We assessed NHs' proportion of PLWD in relation to total and substantiated complaints. Methods: Data were from the ASPEN Complaints/Incident Tracking System and the Certification and Survey Provider Enhanced Reports (2017). NHs (N = 15,499) were categorized based on high (top-10%), medium (middle-80%), and low (bottom-10%) dementia prevalence. Negative binomial Poisson regression assessed complaint patterns in relation to NHs' high/low (vs. medium) proportions of PLWD and other facility/resident characteristics. Results: Compared to NHs with medium-dementia prevalence, NHs with low proportions of PLWD had higher total (average marginal effect [AME] = 0.16, p < 0.001) and substantiated (AME = 0.30, p < 0.001) complaints, whereas NHs with high proportions of PLWD had fewer total (AME= -0.07; p < 0.05) and substantiated (AME= -0.11, p < 0.05) complaints. Also, NHs' profit status, chain-affiliation, size, staffing, and resident ethnicity were associated with total and substantiated complaints. Conclusion: The association between high proportions of PLWD and lower NH complaints suggests either that these NHs have higher overall quality or that complaints are underreported. Regardless, surveyors and families may need more involvement in monitoring higher dementia prevalence facilities.

BACKGROUND: Cognitive function is an important component of healthy ageing. However, it is unclear whether relaxation/meditation practices provide cognitive benefits, particularly in midlife and early late life. Meditative practices are associated with higher self-esteem, and self-esteem serves as a general protective factor for many health outcomes. The current study examines associations between meditation practice, self-esteem, and change over 10 years in midlife cognitive performance. METHODS: Data were from waves 2 (2003-2004) and 3 (2013-2014) of the Midlife in the United States (MIDUS) study. We used structural equation modelling to examine whether persistent meditation practice at both waves or episodic practice at one wave is associated with better cognitive function over 10 years, compared to no meditation practice, while controlling for prior cognitive function and covariates (baseline socio-demographics, health, and functional status). Additionally, we assessed if self-esteem mediates the above associations. RESULTS: We included 2168 individuals (Mage = 65 ± 11). After controlling for covariates, the findings revealed that persistent meditation practice in both waves was associated with significantly less decline in episodic memory; however, no such effects were found for executive function. Further, although participants' higher self-esteem was significantly associated with less decline in executive function and episodic memory, it did not mediate the associations between meditation practice and cognitive functions. CONCLUSIONS: While both persistent meditation practice and self-esteem have associations with cognitive outcomes for middle-aged and older adults in MIDUS, self-esteem as a mediator was not supported. Thus, future investigations should examine mechanisms that underlie these protective factors on cognitive performances across adulthood.

OBJECTIVES: The current study examined whether informal caregivers performed worse, better, or similar to non-caregivers on cognitive tests of executive functioning and episodic memory over 10 years. Methods: Data were from waves 2 (2003-04) and 3 (2013-14) of the Midlife in the United States (MIDUS) study (N = 2086). Multiple linear regression models examined whether caregiving at both waves 2 and 3 predicted better cognitive functioning at wave 3, than caregiving at only one time point or no caregiving (reference) while controlling for baseline covariates (i.e., sociodemographic, health, and functional status). RESULTS: After controlling for covariates, caregiving at both waves was independently associated with better performance in episodic memory (b = .24, SE = .10, p = .013) but not executive function (b = -.06, SE = .05, p = .246). Discussion:The findings partially supported both healthy caregiver and stress process models, indicating caregiving may be associated with better episodic memory but not executive functioning over time among the middle-aged and older adults.
ABSTRACT
This cross-sectional study included 211 employed family caregivers with older relatives living in care facilities in Japan. Using multiple linear regression analysis, we examined the caregiving context after institutionalization of an older family member. Specifically, we examined predictors of negative spillover from caregiving to employment among family caregivers. The outcome was the extent of negative spillover. Primary predictors included caregiver characteristics and postinstitutionalization caregiving contexts such as caregiving tasks and dissatisfaction with institutional care services. Among all caregivers, 134 (63.5%) were female, and approximately half of all caregivers reported satisfaction with institutional care services. We found that dissatisfaction with institutional care services and being a female each had a main effect on greater negative spillover. However, they did not have any interacting effect on negative spillover after the institutionalization. Negative spillover did not terminate when older family members were institutionalized. Higher satisfaction with institutional care may reduce negative spillover.
ABSTRACT
Background and Objectives: Many persons with Alzheimer's disease or related dementias (ADRD) receive care from paid staff in residential communities. The most common staff in these communities are certified nursing assistants (CNAs). Although CNAs have a high number of interactions with residents, and thus the possibility of engaging in social interactions, evidence suggests that they provide limited social support to persons with ADRD. Little is known about the attitudes of CNAs toward providing social support to persons with ADRD and their perception of components of quality social interactions with these individuals. Research Design and Methods: We conducted a thematic analysis of semistructured interviews with 11 CNAs (91% female participants, mean age 23.6) to understand their perceptions about providing social support to persons with ADRD and the components of effective social interactions. Results: Our results show that CNAs consider providing social support to be an important part of their role as CNAs. Additionally, participants emphasized the interplay of verbal communication, nonverbal communication, and internal beliefs and attitudes toward persons with ADRD in creating effective social interactions. Participants highlighted multiple barriers to providing residents with social support, including lack of time, lack of training, and the behavioral and psychological symptoms of dementia. Discussion and Implications: We offer implications for expanding training for CNAs working with persons with dementia and improving policy based on our results.
ABSTRACT
Objectives: Informal caregiving has been associated with higher stress and lower levels of subjective well-being. Mind-body practices including yoga, tai chi, and Pilates also incorporate stress reducing activities. The current study aimed to examine the association between mind-body practice and subjective well-being among informal family caregivers. Methods: A sample of informal caregivers were identified in the Midlife in the United States study (N = 506, M ± SDage = 56 ± 11, 67% women). We coded mind-body practice into three categories, including regular practice (participating in one or more of them "a lot" or "often"), irregular (participating "sometimes" and "rarely") and no practice ("never"). Subjective well-being was measured using the 5-item global life satisfaction scale and the 9-item mindfulness scale. We used multiple linear regression models to examine associations between mind-body practice and caregivers' subjective well-being, controlling for covariates of sociodemographic factors, health, functional status, and caregiving characteristics. Results: Regular practice was associated with both better mindfulness-related well-being (b = 2.26, p < .05) and better life satisfaction (b = 0.43, p < .05), after controlling for covariates. Discussion: Future research should examine whether there is a selection effect of caregivers with higher well-being being more likely to choose these activities, and/or if mind-body practices are effective non-pharmacological interventions to improve family caregivers' quality of life.
ABSTRACT
Resident complaints are vital to understanding nursing home (NH) quality. Using complaints as facility- and resident-level outcomes, this study replicates prior analyses (spanning 1998-2002 and 2007-2012) with 2013-2017 data, the phase prior to NH regulatory changes initiated in November, 2017. Advancing prior papers, we analyze the number of complaints, allegations, and deficiency citations separately. Between 2013-2017, 458,101 total complaints (5.9/NH/year) were identified, containing 949,466 allegations (12.2/NH/year), and resulting in the issuance of 156,135 deficiency citations (2.0/NH/year) in about 15,600 NHs across the country. Regarding the number of complaints, substantiated complaints, and deficiency citations, results show a steady increase compared to previous years. Furthermore, there are marked differences among the CMS survey regions on the prevalence of overall complaints, substantiated complaints, and deficiency citations. However, the average rate of substantiation of complaint allegations shows a decreasing trend over these years, suggesting that complaints may have increased due to higher care expectations.

Although approximately a third of individuals with intellectual and developmental disabilities (IDD) also experience a mental health concern, caregivers often miss early identification of these issues. In this perspective piece, we present an outline for a mental health literacy program that can enhance existing training approaches for caregivers of individuals with IDD. We describe three processes of the Mental Health Awareness and Advocacy (MHAA) curriculum and detail how it provides a strong preventative model to train caregivers to increase their mental health literacy. In describing these processes, we provide illustrative examples and conclude by providing a brief vignette that highlights how this process could be used by caregivers to help reduce mental health concerns in individuals with IDD.

OBJECTIVES: Dementia family caregivers report poor sleep and mood, typically attributed to chronic stress and managing frequent daily stressors. Although many studies use global retrospective reports of these indicators, the current study examines mechanisms linking sleep, negative affect, stress biomarkers, and high-/low-stress contexts at the daily level, from the biopsychosocial perspective of stressor exposure and reactivity. METHOD: One hundred seventy-three caregivers (Mage = 61.97, SD = 10.66) were providing care at home and used adult day services (ADS) at least 2 days a week. Caregivers reported their bedtime, wake time, sleep quality, and nighttime problems of the person with dementia (PwD) daily for eight consecutive days, concurrently reporting noncare stressors, negative affect, and providing five salivary cortisol samples per day. We conducted multilevel analysis to examine whether caregiver sleep characteristics overnight (i.e., total time in bed, quality, and PwD sleep problems) were associated with their anxious and depressive symptoms on days where ADS were utilized versus non-ADS days (i.e., low stress vs. high stress), and whether cortisol daily total output as area under the curve (AUCg) mediated the direct associations, at the within- and between-person levels. RESULTS: On high-stress (i.e., non-ADS) days when caregivers had a longer time in bed than usual the night before, they were less anxious on the following day; the direct association was statistically mediated through lower cortisol AUCg during the day. DISCUSSION: Staying longer in bed than usual before an upcoming high-stress day may help dementia family caregivers better regulate cortisol stress reactivity and anxious symptoms.

BACKGROUND: Mental health literacy (MHL) programs are a promising approach to help prevent mental health issues (MHI) among college students; however, there is an increasing need to understand individual factors that influence the development of students' MHL. AIMS: Following a strengths-based approach, we examined if college students' individual characteristics and MHI experience were associated with students' MHL. METHODS: Using two vastly different college samples (Sample 1, N = 617; Sample 2, N = 306), we used the Mental Health Awareness and Advocacy framework, guided by the health belief model and social-cognitive theory, to investigate associations between students' mental health literacy, demographic factors, and their previous experience with MHI. RESULTS: Results from nested regression analyses suggest that personal experiences with MHI are associated with higher MHL (knowledge, self-efficacy, and behaviors), even after controlling for key individual characteristics. Prior experience with having an MHI and receiving therapy appeared to be most important in explaining MHL behaviors. CONCLUSIONS: Students with personal experience with an MHI may be one of the most valuable resources for increasing MHL and utilization of mental health resources on college campuses. Additional implications and future research directions are offered.
ABSTRACT
BACKGROUND: Although there is a general trend of functional decline with age, there lacks an understanding of how cancer diagnosis and other factors may contribute to this trend. This study aimed to examine functional limitation trajectories among adults with and without cancer, and before versus after the cancer diagnosis, and to explore potential contributing factors associated with functional trajectories among cancer survivors. METHODS: The sample were middle-aged and older Chinese adults who participated in all 3 waves of the China Health and Retirement Longitudinal Study (CHARLS, 2011-2015). Ordinary and multiphase growth curve analyses were conducted to examine (1) differences in functional trajectories between participants with (n = 139) and without cancer (n = 7,313), (2) pre-and post-cancer diagnosis changes in functional limitations among those who reported a cancer diagnosis over the 4-year timeframe, and (3) contributing factors associated with functional trajectories among cancer survivors, guided by the Disablement Process Models, including psychological (depressive symptoms), physical (pain and falls), cognitive (self-reported memory problems), and environmental (social contact and available support) factors. RESULTS: There was a trend of increased functional limitations among all participants over time (unstandardized ß = 0.17, p < .0001). However, participants with cancer did not differ from non-cancer participants in neither the level (unstandardized ß = 0.77, p = .08) nor the rate of functional decline (unstandardized ß = -0.43, p = .07). Functional limitation trajectories were different pre- versus post-cancer diagnosis, although not in expected directions (unstandardized ß = -0.48, p < .05). Cancer survivors with greater pain had higher levels of functional limitations which were sustained over time compared to those with less pain (unstandardized ß = 0.93, p < .001). CONCLUSIONS: The study confirmed that Chinese middle-aged and older adults had overall decreased functional decline over time. A novel finding that cancer survivors experienced less rapidly functional decline after the cancer diagnosis suggested that cancer diagnosis might serve as an inflection point at which early intervention is promising to slow the functional decline. In addition, findings that within-person contributing factors, such as pain, can be influential in functional limitation trajectories suggested that more attention is needed to pay to patients with cancer-pain. These findings demonstrated the heterogeneity of functional limitation trajectories and needs for person-centered interventions among Chinese cancer survivors.

Mental health literacy (MHL) training is essential in college environments. These programs are commonly delivered in-person via workshops or for-credit courses. Campuses now seek high-quality online options. We compare the effectiveness of a for-credit MHL course against a comparison course, focusing on whether online asynchronous delivery was as effective as in-person synchronous delivery. This quasi-experimental pretest/posttest treatment/comparison study included 1049 participants across five semesters (pre-COVID-19) who were 18 years or older and self-selected enrollment in a Mental Health Awareness and Advocacy (MHAA) course (treatment; n = 474) or a general lifespan development course (comparison; n = 575). Using linear mixed effect modeling, changes in MHL were compared across groups and across online/in-person modalities. Students in the treatment group significantly increased their MHL knowledge (ß Identifying = .49, p < .001; ß Locating = .32, p < .001; ß Responding = .46, p < .001) and self-efficacy (ß = .27, p < .001), and treatment effects did not differ across modalities. With increased concern regarding mental health issues of isolated college students during the COVID-19 pandemic, this study supports the efficacy of delivering MHL courses online.

OBJECTIVES: Psychosocial and cognitive-behavioral dementia caregiver interventions are effective, yet accessing counselor/therapist-led programs can be costly and difficult. Face-to-face therapist-led Acceptance and Commitment Therapy (ACT) is highly effective in dementia caregivers, as established by two different randomized control trials. The current study evaluates a pilot ACT for Caregivers program, which is a community-based, self-guided, online adaptation of ACT. METHOD: Participants (N = 51; Mage=66.0 S. D =11.7, 80% women) completed 10 self-guided sessions teaching ACT, along with accessing an online dementia education library. RESULTS: Repeated measures ANOVA from pre-, posttest, and 4-week follow-up demonstrated decreased depressive symptoms, burden, and stress reactions to behavioral symptoms, and increased positive aspects of caregiving and quality of life. ACT-specific measures improved, with decreases in cognitive fusion and psychological inflexibility (AAQ-II), and improvements in living according to personal values (ValuingProgress increased; ValuingObstruction decreased). All outcomes were statistically significant (at p < .01) and sustained over 4-week follow-up. Although this was a non-clinical sample, the program demonstrated clinical significance, as average depressive symptoms were at the clinical cutoff at baseline, but one standard deviation below clinical cut-off at post-test and 4-week followup. Use of education materials was low (29% of participants used these, albeit rating them helpful), suggesting that ACT likely contributed more to overall improvements. CONCLUSION: The online ACT for Caregivers pilot program offers an empirically supported translation of traditional ACT, improving accessibility, and affordability for family dementia caregivers.

The purpose of this study was to identify predictive factors of effort-reward imbalance (ERI) among employees in multiple long-term care settings in Japan. This cross-sectional study by convenience sampling included 944 participants providing three types of long-term care: home-based (n = 201), community-based (n = 128), and institutional (n = 615). Multiple logistic regression analysis was used to identify factors associated with self-reported ERI. Low job satisfaction, being a care manager, holding a position of department head, working long hours, and having family-related stress were the common factors associated with ERI in employees across all three types of long-term care setting. Long-term care providers should consider the needs of care recipients and their family, as well as the needs of care employees, maximizing rewards so that turnover can be reduced and the diversity of individual work-family needs can be accommodated across multiple forms of long-term care settings.

OBJECTIVE: Grip strength is a widely used motor assessment in ageing research and has repeatedly been shown to be associated with cognition. It has been proposed that grip strength could enhance cognitive screening in experimental or clinical research, but this study uses multiple data-driven approaches to caution against this interpretation. Furthermore, we introduce an alternative motor assessment, comparable to grip dynamometry, but has a more robust relationship with cognition among older adults. DESIGN: Associations between grip strength and cognition (measured with the Montreal Cognitive Assessment) were analysed cross sectionally using multivariate regression in two datasets: (1) The Irish LongituDinal Study on Ageing (TILDA; N = 5,980, community-dwelling adults ages 49-80) and (2) an experimental dataset (N = 250, community-dwelling adults aged 39-98). Additional statistical simulations on TILDA tested how ceiling effects or skewness in these variables influenced these associations for quality control. RESULTS: Grip strength was significantly but weakly associated with cognition, consistent with previous studies. Simulations revealed this was not due to skewness/ceiling effects. Conversely, a new alternative motor assessment (functional reaching [FR]) had a stronger, more robust and more sensitive relationship with cognition compared to grip strength. CONCLUSIONS: Grip strength should be cautiously interpreted as being associated with cognition. However, FR may have a stronger and clinically useful relationship with cognition.

OBJECTIVES: With high numbers of persons with dementia living in residential care, it is vital to maximize psychosocial well-being for this population in this setting. The current study observed whether proportions of positive affect in residents differed based on co-occurring staff (typically certified nurse assistants) interaction types. METHODS: A trained research team observed staff/resident interactions and affect in residents with dementia in common areas of a residential memory care unit (n = 22; observations over one year, or 6999 minutes total). RESULTS: The most observed resident affect type was neutral (53.1% of all minutes observed), followed by positive affect (44.5%). The most common staff interaction type was neutral/no interaction (81.1% of all minutes observed), followed by positive staff interactions (18.1%). There was very little resident negative affect (2.4%) and staff negative interactions (.8%) observed. When staff had neutral/no/negative interactions, residents were positive 36% of the time, whereas when staff had positive interactions with them, residents were positive 81% of the time (z = 28.84, p < .001). A qualitative review of field notes identified themes and subthemes providing a more thorough understanding and context for the resident affect and staff interactions. While quantitative analyses suggested low rates of negative staff interaction, field notes highlight that neutral or no interactions with residents sometimes comprised missed opportunities, as well as more problematic lack of interaction (ignoring). CONCLUSIONS: Not just avoiding negative interactions, but eliciting positive social interactions between staff and residents is important in promoting positive affect and overall wellbeing in persons with dementia.
