Linking openness to cognitive ability in older adulthood: The role of activity diversity.

Relatively few studies have examined the reasons older individuals participate in activities that may benefit cognition with aging. Personality traits, particularly, openness to experience, are likely to influence how activities are selected. Openness to experience has also reliably shown to relate to cognitive and intellectual capacities. The current study tested whether diversity in activity helped to explain the overlap between openness to experience and cognitive functioning in an older adult sample (n = 476, mean age: 72.5 years). Results suggest that openness is a better predictor of activity diversity than of time spent engaged in activities or time spent in cognitively challenging activities. Further, activity diversity explained significant variance in the relationship between openness and cognitive ability for most constructs examined. This relationship did not vary with age, but differed as a function of education level, such that participating in a more diverse array of activities was most beneficial for those with less formal education. These results suggest that engagement with a diverse behavioral repertoire in late life may compensate for lack of early life resources.

Association of physical functioning of persons with dementia with caregiver burden and depression in dementia caregivers: an integrative data analysis.

OBJECTIVES: To determine whether caregiver relationship and race modify associations between physical functioning of persons with dementia (PWD) and their caregiver's burden and general depressive symptoms. METHOD: We pooled data from four behavioral intervention trials (N = 1,211). Using latent growth modeling, we evaluated associations of PWD physical functioning with the level and rate of change in caregiver burden and caregivers' general depressive symptoms and stratified these associations by caregiver relationship and race. RESULTS: PWD were, on average, 81 years old (68% female) with mean follow-up of 0.5 years. More baseline PWD physical impairment was associated with less worsening in caregiver burden over time (ß = -0.23, 95% CI: -0.29, -0.14), but this relationship was not modified by caregiver characteristics. More impaired baseline PWD physical functioning was not associated with changes in depressive symptoms (ß = -0.08, 95% CI: -0.17, 0.00), but was associated with less worsening in depressive symptoms among spousal (ß = -0.08, 95% CI: -0.17, 0.00) and non-white (ß = -0.08, 95% CI: -0.17, 0.00) caregivers. CONCLUSIONS: Dementia caregivers may experience reduced caregiver-related burden because of adjustment to PWD functional status, while spousal and non-white caregivers may experience less depressive symptoms resultant of adjustment to functional status.

Impact of Experience Corps® Participation on Children's Academic Achievement and School Behavior.

This article reports on the impact of the Experience Corps® (EC) Baltimore program, an intergenerational, school-based program aimed at improving academic achievement and reducing disruptive school behavior in urban, elementary school students in Kindergarten through third grade (K-3). Teams of adult volunteers aged 60 and older were placed in public schools, serving 15 h or more per week, to perform meaningful and important roles to improve the educational outcomes of children and the health and well-being of volunteers. Findings indicate no significant impact of the EC program on standardized reading or mathematical achievement test scores among children in grades 1-3 exposed to the program. K-1st grade students in EC schools had fewer principal office referrals compared to K-1st grade students in matched control schools during their second year in the EC program; second graders in EC schools had fewer suspensions and expulsions than second graders in non-EC schools during their first year in the EC program. In general, both boys and girls appeared to benefit from the EC program in school behavior. The results suggest that a volunteer engagement program for older adults can be modestly effective for improving selective aspects of classroom behavior among elementary school students in under-resourced, urban schools, but there were no significant improvements in academic achievement. More work is needed to identify individual- and school-level factors that may help account for these results.

Valued activities among individuals with and without functional impairments: Findings from the National Health and Aging Trends study (NHATS).

Using the National Health and Aging Trends Study (NHATS), we examined baseline activity and functional status. Respondents were classified as High (n=1,662), Moderate (n=1,973), or Low (n=989) Function and rated importance of and actual participation in four activities. Transportation and health were also examined. Individuals classified as low function were less likely to engage in valued activities and more likely to report that poor health and transportation limited participation, compared to individuals with no or moderate functional impairments. Data suggest the importance of developing interventions which bridge the gap between activity preferences and participation for older adults with functional limitations.

Valuation of Life as outcome and mediator of a depression intervention for older African Americans: the Get Busy Get Better Trial.

OBJECTIVE: Previously, we showed that Get Busy Get Better (GBGB), a 10-session multicomponent home-based, behavioral intervention, reduced depressive symptom severity in older African Americans. As appraising the value of life is associated with depressive symptoms, this study examined whether GBGB enhanced positive appraisals of life and if, in turn, this mediated treatment effects on depressive symptoms. METHODS: Data were from a single-blind parallel randomized trial involving 208 African Americans (≥55 years old) with depressive symptoms (Patient Health Questionnaire, PHQ-9 ≥5). GBGB involved five components: care management, referral/linkage, stress reduction, depression education, and behavioral activation. A 13-item Valuation of Life (VOL) scale with two subfactors (optimism and engagement) was examined as an outcome and as mediating GBGB effects on PHQ-9 scores at 4 months. RESULTS: Of 208 enrolled African Americans, 180 completed the 4-month interview (87 = GBGB; 93 = control). At 4 months, compared with wait-list control group participants, the GBGB group had improved VOL (difference in mean changes from baseline = 4.67, 95% confidence interval 2.53, 6.80). Structural equation models indicated that enhanced VOL mediated a significant proportion of GBGB's impact on depressive symptoms, explaining 71% of its total effect, and its subfactors (optimism, explaining 67%; engagement, 52%). CONCLUSION: Valuation of Life appears malleable through an intervention providing resources and activation skills. GBGB's impact on depressive symptoms is attributed in large part to participants' enhanced attachment to life. Attention to VOL as mediator and outcome and the reciprocal relationship between mood and attachment to life is warranted. Copyright © 2017 John Wiley & Sons, Ltd.

Framed, Interactive Theory-Driven Texting: Effects of Message Framing on Health Behavior Change for Weight Loss.

More approaches to support weight control are needed, especially among racial minorities who shoulder a disproportionate obesity burden. Using an approach influenced by regulatory fit theory, we conducted a 28-day, 4-arm experimental trial with 89 obese adults recruited from urban, predominantly African American churches to ascertain the efficacy of framed text messages to motivate behaviors conducive to weight loss. Participants were assigned to receive message framing that was matched versus mismatched to their motivational orientation. Results were mixed overall; however, matched texts elicited greater motivation to change eating and exercise behavior, suggesting promise in using motivational approaches to tailor messages.

Motivators, Barriers, and Facilitators to Weight Loss and Behavior Change Among African American Adults in Baltimore City: A Qualitative Analysis.

BACKGROUND: African American adults achieve smaller amounts of weight loss than their white counterparts when exposed to the same intervention and are more likely to regain weight during long-term follow-up. OBJECTIVE: To identify perceived motivators, barriers, and facilitators to weight loss and behavior change among African American adults. METHODS: Two focus groups were conducted between April and May 2015 at an urban community health center in Baltimore City, Maryland. A total of 13 participants took part in the discussions. Eligible participants were obese (BMI 30+) African American adults aged 21-70 who had at least one obesity-related comorbidity. Discussion questions were designed to identify the personal, social, and environmental factors that influence weight loss and behavior change among urban minority populations. RESULTS: Statements were first classified as a motivator, barrier, or facilitator, then divided further as a personal, social, or environmental factor influencing weight loss and behavior change. Among the findings, several novel motivators (reducing or eliminating medication, improving physical intimacy) and barriers (personal transportation, lack of access to scales) emerged that were not previously characterized in the existing literature. CONCLUSIONS: This study was intended to provide preliminary evidence that may be used to guide the development of innovative and culturally relevant weight-loss interventions in the future. Results are applicable to similar urban minority populations.

The association of adverse childhood experiences with mid-life depressive symptoms and quality of life among incarcerated males: exploring multiple mediation.

OBJECTIVES: To explore the association of experiencing death, trauma, and abuse during childhood with depressive symptoms and quality of life at mid-life among incarcerated men and to understand how current social support and coping strategies mediate the impact of childhood trauma histories on mental health. METHODS: Study participants were 192 male inmates in a maximum security prison. Participants completed measures of adverse childhood experiences related to death, trauma, and abuse, and depressive symptoms and quality of life. Data were analyzed using multiple mediation modeling. RESULTS: Men who reported having experienced adverse childhood experiences reported more depressive symptoms and lower quality of life than their counterparts. The results showed that in models both unadjusted and adjusted for age, race, education, number of years served, and whether the inmate had a life sentence, the association between adverse childhood experiences and quality of life were partially explained by the total of the indirect effects (point estimate = -.5052; CI.95 = -1.0364, -.0429 and point estimate = -.7792; CI.95 = -1.6369, -.0381), primarily via social support. However, the associations between adverse childhood experiences and depressive symptoms were not explained by social support and coping. CONCLUSION: Adverse childhood experiences are associated with deleterious mental health effects in later life. Social support and coping partially mediate the association between adverse childhood experiences and quality of life. The high prevalence of childhood trauma among aging prison inmates warrants attention to increasing social support mechanisms to improve mental health.

School climate: perceptual differences between students, parents, and school staff.

Research suggests that school climate can have a great impact on student, teacher, and school outcomes. However, it is often assessed as a summary measure, without taking into account multiple perspectives (student, teacher, parent) or examining subdimensions within the broader construct. In this study, we assessed school climate from the perspective of students, staff, and parents within a large, urban school district using multilevel modeling techniques to examine within- and between-school variance. After adjusting for school-level demographic characteristics, students reported worse perceptions of safety and connectedness compared to both parent and staff ratings (all p < 0.05). Parents gave the lowest ratings of parental involvement, and staff gave the lowest ratings of academic emphasis (ps < 0.05). Findings demonstrate the importance of considering the type of informant when evaluating climate ratings within a school. Understanding how perceptions differ between informants can inform interventions to improve perceptions and prevent adverse outcomes.

Increases in lifestyle activities as a result of experience Corps® participation.

Experience Corps® (EC) was designed to simultaneously increase cognitive, social, and physical activity through high-intensity volunteerism in elementary school classrooms. It is, therefore, highly likely that EC participation may alter pre-existing patterns of lifestyle activity. This study examined the impact of "real-world" volunteer engagement on the frequency of participation in various lifestyle activities over a 2-year period. Specifically, we examined intervention-related changes on reported activity levels at 12 and 24 months post-baseline using Intention-to-Treat (ITT) and Complier Average Causal Effect (CACE) analyses, which account for the amount of program exposure. ITT analyses indicated that, compared to the control group, EC participants reported modest increases (approximately half a day/month) in overall activity level, especially in intellectual and physical activities 12 months post-baseline. Increases in activity were not found at the 24-month assessment. CACE models revealed similar findings for overall activity as well as for intellectual and physical activities at 12 months. Additionally, CACE findings suggested modest increases in social activity at 12 months and in intellectual and passive activities at 24 months post-baseline. This community-based, health promotion intervention has the potential to impact lifestyle activity, which may lead to long-term increases in activity and to other positive cognitive, physical, and psychosocial health outcomes.

Impact of Experience Corps(®) participation on school climate.

We examined the impact of the Experience Corps(®) (EC) program on school climate within Baltimore City public elementary schools. In this program, teams of older adult volunteers were placed in high intensity (>15 h per week), meaningful roles in public elementary schools, to improve the educational outcomes of children as well as the health and well-being of volunteers. During the first year of EC participation, school climate was perceived more favorably among staff and students in EC schools as compared to those in comparison schools. However, with a few notable exceptions, perceived school climate did not differ for staff or students in intervention and comparison schools during the second year of exposure to the EC program. These findings suggest that perceptions of school climate may be altered by introducing a new program into elementary schools; however, research examining how perceptions of school climate are impacted over a longer period is warranted.

Impact of the Baltimore Experience Corps Trial on cortical and hippocampal volumes.

INTRODUCTION: There is a substantial interest in identifying interventions that can protect and buffer older adults from atrophy in the cortex and particularly, the hippocampus, a region important to memory. We report the 2-year effects of a randomized controlled trial of an intergenerational social health promotion program on older men's and women's brain volumes. METHODS: The Brain Health Study simultaneously enrolled, evaluated, and randomized 111 men and women (58 interventions; 53 controls) within the Baltimore Experience Corps Trial to evaluate the intervention impact on biomarkers of brain health at baseline and annual follow-ups during the 2-year trial exposure. RESULTS: Intention-to-treat analyses on cortical and hippocampal volumes for full and sex-stratified samples revealed program-specific increases in volumes that reached significance in men only (P's ≤ .04). Although men in the control arm exhibited age-related declines for 2 years, men in the Experience Corps arm showed a 0.7% to 1.6% increase in brain volumes. Women also exhibited modest intervention-specific gains of 0.3% to 0.54% by the second year of exposure that contrasted with declines of about 1% among women in the control group. DISCUSSION: These findings showed that purposeful activity embedded within a social health promotion program halted and, in men, reversed declines in brain volume in regions vulnerable to dementia. CLINICAL TRIAL REGISTRATION: NCT0038.

The Moderating Effect of Personality Type on the Relationship between Leisure Activity and Executive Control in Older Adults.

We examined the moderating effect of personality on the association between leisure activities and executive control in healthy community-dwelling older adults. We found two distinct personality typologies: individuals with a Resilient personality were characterized by emotional stability and self-confidence; whereas, those who resembled an Overcontrolled personality tended to be introverted, but also low on neuroticism. Resilient individuals were more likely than Overcontrolled individuals to demonstrate higher executive function and attention as a result of participation in mental activities. These results suggest that personality might be important to include in studies that test the efficacy of activity interventions for improving cognition.

Personality and cognitive decline in the Baltimore Epidemiologic Catchment Area follow-up study.

OBJECTIVE: To determine the association between personality domains and 11-year cognitive decline in a sample from a population-based study. METHOD: Data from Waves 3 (1993-1996) and 4 (2003-2004) of the Baltimore cohort of the Epidemiologic Catchment Area (ECA) study were used for analyses. The sample included 561 adults (mean age ± SD: 45.2 ± 10.78 years) who completed the NEO Personality Inventory-Revised prior to Wave 4. Participants also completed the Mini-Mental State Examination (MMSE) and immediate and delayed word recall tests at Wave 3, and at Wave 4, 10.9 ± 0.6 years later. RESULTS: In models adjusted for baseline cognitive performance, demographic characteristics, medical conditions, depressive symptoms, and psychotropic medication use, each 10-point increase in Neuroticism T-scores was associated with a 0.15-point decrease in MMSE scores (B = -0.15, 95% confidence interval [CI]: -0.30, -0.01), whereas each 10-point increase in Conscientiousness T-scores was associated with a 0.18-point increase on the MMSE (B = 0.18, 95% CI: 0.04, 0.32) and a 0.21-point increase in immediate recall (B = 0.21, 95% CI: 0.003, 0.41) between baseline and follow-up. CONCLUSION: Findings suggest that greater Neuroticism is associated with decline, and greater Conscientiousness is associated with improvement in performance on measures of general cognitive function and memory in adults. Further studies are needed to determine the extent to which personality traits in midlife are associated with clinically significant cognitive outcomes in older adults, such as mild cognitive impairment and dementia, and to identify potential mediators of the association between personality and cognitive trajectories.

Neighborhood physical disorder, social cohesion, and insomnia: results from participants over age 50 in the Health and Retirement Study.

ABSTRACT Background: We determined the association between neighborhood socio-environmental factors and insomnia symptoms in a nationally representative sample of US adults aged >50 years. Methods: Data were analyzed from two waves (2006 and 2010) of the Health and Retirement Study using 7,231 community-dwelling participants (3,054 men and 4,177 women) in the United States. Primary predictors were neighborhood physical disorder (e.g. vandalism/graffiti, feeling safe alone after dark, and cleanliness) and social cohesion (e.g. friendliness of people, availability of help when needed, etc.); outcomes were insomnia symptoms (trouble falling asleep, night awakenings, waking too early, and feeling unrested). Results: After adjustment for age, income, race, education, sex, chronic diseases, body mass index, depressive symptoms, smoking, and alcohol consumption, each one-unit increase in neighborhood physical disorder was associated with a greater odds of trouble falling asleep (odds ratio (OR) = 1.09, 95% confidence interval (CI): 1.04-1.14), waking too early (OR = 1.05, 95% CI: 1.00-1.10), and, in adults aged ≥69 years (adjusting for all variables above except age), feeling unrested in the morning (OR = 1.11, 95% CI: 1.02-1.22 in 2006). Each one-unit increase in lower social cohesion was associated with a greater odds of trouble falling asleep (OR = 1.06, 95% CI: 1.01-1.11) and feeling unrested (OR = 1.09, 95% CI: 1.04-1.15). Conclusions: Neighborhood-level factors of physical disorder and social cohesion are associated with insomnia symptoms in middle-aged and older adults. Neighborhood-level factors may affect sleep, and consequently health, in our aging population.

Modelling longitudinal changes in older adults' memory for spoken discourse: findings from the ACTIVE cohort.

Episodic memory shows substantial declines with advancing age, but research on longitudinal trajectories of spoken discourse memory (SDM) in older adulthood is limited. Using parallel process latent growth curve models, we examined 10 years of longitudinal data from the no-contact control group (N = 698) of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) randomised controlled trial in order to test (1) the degree to which SDM declines with advancing age, (2) the predictors of these age-related declines and (3) the within-person relationship between longitudinal changes in SDM and longitudinal changes in fluid reasoning and verbal ability over 10 years, independent of age. Individuals who were younger, were White, had more years of formal education, were male and had better global cognitive function and episodic memory performance at baseline demonstrated greater levels of SDM on average. However, only age at baseline uniquely predicted longitudinal changes in SDM, such that declines accelerated with greater age. Independent of age, within-person decline in reasoning ability over the 10-year study period was substantially correlated with decline in SDM (r = .87). An analogous association with SDM did not hold for verbal ability. The findings suggest that longitudinal declines in fluid cognition are associated with reduced spoken language comprehension. Unlike findings from memory for written prose, preserved verbal ability may not protect against developmental declines in memory for speech.

The Association Between Lifestyle Activities and Late-Life Depressive Symptoms.

The association between lifestyle activities and incident depressive symptoms was examined within the Women's Health and Aging Study II. Measures of activity and depressive symptoms were collected on four occasions, spanning six-years. Discrete-time Cox proportional hazards models were employed to examine the effects of baseline activity on depressive symptoms over time. Overall, activity was not associated with incident depressive symptoms. When specific activity domains were examined, greater participation in creative activities was associated with a reduced risk of depressive symptoms (hazard ratio = 0.92; CI 95% 0.87, 0.98). Further longitudinal research between diverse activities and incident depressive symptoms is warranted.

Associations Between Body Mass Index and Cognitive Change in the ACTIVE Study: Variations by Race and Social Determinants of Health.

Objectives: The current study examines relationships between Body Mass Index (BMI) and cognitive performance and change in processing speed, memory, and reasoning, while accounting for variations by race and the influence of social determinants of health. Methods: Secondary data analysis of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, which included participants who self-identified as African American or Black (n = 728) and White (n = 2028). Latent growth curve modeling was used to assess study aims. Results: Increases in BMI were associated with less cognitive decline over 10 years across each cognition domain. Race moderation effects were noted for speed and memory. Relationships between BMI and cognitive trajectories were mediated by economic stability for speed and reasoning. Discussion: Overall, these findings are consistent with the "obesity paradox." Further research is needed to elucidate patterns of results by race.

Rural-Urban Differences in Cognition: Findings From the Advanced Cognitive Training for Independent and Vital Elderly Trial.

ObjectivesWe examined associations between three geographic areas (urban, suburban, rural) and cognition (memory, reasoning, processing speed) over a 10-year period. Methods: Data were obtained from 2539 participants in the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) trial. Multilevel, mixed-effects linear regression was used to estimate cognitive trajectories by geographical areas over 10 years, after adjusting for social determinants of health. Results: Compared to urban and suburban participants, rural participants fared worse on all cognitive measures-memory (B = -1.17 (0.17)), reasoning (B = -1.55 (0.19)), and processing speed (B = 0.76 (0.19)) across the 10-year trajectory. Across geographic areas, greater economic stability, health care access and quality, and neighborhood resources were associated with better cognition over time. Discussion: Findings highlight the importance of geographical location when examining cognition later in life. More research examining place-based life experiences is needed to make the greatest impact on geographically diverse communities.

Methods and operational aspects of human-centred design into research processes for individuals with multiple chronic conditions: A survey study.

AIM: To examine ways in which human-centred design was integrated into a nursing school's research processes involving individuals with multiple chronic conditions. DESIGN: Cross-sectional survey study. METHODS: Three surveys were sent out, with surveys 1 and 2 involving faculty who had worked closely with design strategists and survey 3 as a school-wide survey eliciting experience with human-centred design, respectively. RESULTS: Survey respondents (n = 7 for surveys 1 and 2 and n = 36 for survey 3) had no or minimal experience with human-centred design. Faculty respondents indicated it helped engaging various stakeholders, particularly in intervention development. Key lessons learned included: (1) the importance of designer involvement from study conception, (2) distinguishing a design strategist's skillset from strictly visual design, (3) challenges during the ethical review processes, and (4) sustainability of resources. The dynamic approach of human-centred design has benefited our efforts to advance the science of caring for individuals with multiple chronic conditions.
