  • sense of belonging to the community in continuing care Retirement Communities and adult day care centers the role of the social network
    Journal of Community Psychology, 2020
    Co-Authors: Liat Ayalon
    Abstract:

    AIM This study examined the contribution of the social network to one's sense of belonging to the community (SCB) in two different long-term care settings: Continuing care Retirement Communities (CCRCs) and adult day care centers (ADCCs). METHODS Overall, 245 respondents participated in both waves of the study that were spaced about 1 year apart. RESULTS Results show that constraint in the social network (e.g., being socially invested in a single group of interconnected ties) is particularly detrimental for CCRC residents, but not for ADCC participants. Betweenness, defined as the number of shortest paths that pass through the focal person, was not significantly related to SCB. In addition, the size of the egocentric network, obtained through a name generator of a list of all potentially meaningful individuals identified by respondents, was directly correlated with SCB at follow-up. CONCLUSIONS The findings are discussed in light of differences between the two long-term care settings and the different social network indicators examined in this study.

  • capturing change and stability in longitudinal qualitative research insights from a study about aging and life transitions in israeli continuing care Retirement Communities
    Educational Gerontology, 2018
    Co-Authors: Liat Ayalon, Andrea Nevedal, Sherylyn H Briller
    Abstract:

    ABSTRACTThe present paper considers the use of longitudinal qualitative research (LQR) as a means to capture both change and stability in people’s lives. We use an LQR study conducted in continuing care Retirement Communities to demonstrate three dimensions that should be taken into consideration when addressing change vs. stability. Three waves of interviews with older adults and their family members as well as memos and reflections concerning interview data are used. The first dimension concerns the question of: “who defines change?” A second dimension raises the question of, “what has changed?” Finally, a third dimension concerns the timeframe of change. We argue that LQR provides a tremendous richness of time dimensions and perspectives. Discrepancies between dimensions, perspectives and timeframes can be particularly enriching. Moreover, LQR allows also for the opportunity to examine stability.

  • from a bird s eye view whole social networks in adult day care centers and continuing care Retirement Communities
    Innovation in Aging, 2018
    Co-Authors: Liat Ayalon, Inbal Yahav, Ofrit Lesser
    Abstract:

    Background and objectives The present study describes whole social networks in 4 adult day care centers (ADCCs) and 4 continuing care Retirement Communities (CCRCs) in Israel. Method Each respondent received a list of names of all individuals receiving services in the respective ADCC or CCRC and was asked to indicate whom he/she knows from the list. We derived whole social network properties and used hierarchical cluster analysis to group network settings. We further examined the ability of the social network data to classify respondents as members of either an ADCC or a CCRC. Results Many social network properties were more favorable in CCRCs than in ADCCs. A striking finding of the present study is that one can classify with a relatively high degree of accuracy a respondent as belonging to an ADCC or a CCRC, simply based on his or her social properties (specifically, number of people who know the participant and are known by the participant). Implications Despite some similarities between CCRCs and ADCCs, CCRCs likely allow for more inclusive and active social relations. This information should be valuable to administrators and care providers.

  • loneliness and anxiety about aging in adult day care centers and continuing care Retirement Communities
    Innovation in Aging, 2018
    Co-Authors: Liat Ayalon
    Abstract:

    Background and Objectives The present study compares how 2 settings: adult day care centers (ADCCs) and continuing care Retirement Communities (CCRCs) fare with regard to loneliness and anxiety about aging. Loneliness is a highly prevalent and distressing subjective experience of inadequate social relations, which has negative effects on health and well-being. Anxiety about aging is defined as worries brought up by imagining the negative consequences and losses associated with old age. The study also examines whether anxiety about aging accounts for differences in loneliness between the 2 settings. This study took place in Israel, where ADCCs are funded by the National Insurance Institute of Israel and CCRCs tend to be funded by private income and wealth. Despite notable differences between the settings, a common goal of both is to reduce loneliness among older adults. Research Design and Methods A cross-sectional design of 4 ADCCs and 4 CCRCs (N = 456). Results Compared with CCRC residents, older adults in ADCCs reported higher levels of loneliness (Mean [SD] = 1.46 [0.60], Mean [SD] = 1.78 [0.80], respectively, t [df]= -5.10 [448], p < .001) and higher levels of anxiety about aging (Mean [SD] = 2.96 [0.88], Mean [SD] = 3.27 [0.99], respectively, t [df] = -3.42 [440], p < .001). Anxiety about aging partially accounted for the differences between the 2 settings in levels of loneliness (B = 0.03, 95% confidence interval [CI]: 0.0037-0.0651). Discussion and Implications Although it is not possible to determine causality from this cross-sectional design, it is possible that CCRCs provide a better social outlet for older adults than ADCCs.

  • changes in moderate intensity physical activity are associated with better cognition in the multilevel intervention for physical activity in Retirement Communities miparc study
    American Journal of Geriatric Psychiatry, 2019
    Co-Authors: Zvinka Z Zlatar, Katie Crist, Jacqueline Kerr, Suneeta Godbole, Michelle Takemoto, Cynthia Castro M Sweet, Dori E Rosenberg
    Abstract:

    ABSTRACT Objective The authors investigated if the physical activity increases observed in the Multilevel Intervention for Physical Activity in Retirement Communities (MIPARC) improved cognitive functions in older adults. The authors also examined if within-person changes in moderate to vigorous physical activity (MVPA), as opposed to low-light and high-light physical activity, were related to cognitive improvements in the entire sample. Methods This was a cluster randomized control trial set in Retirement Communities in San Diego County, CA. A total of 307 older adults without a formal diagnosis of dementia (mean age: 83 years; age range: 67–100; standard deviation: 6.4 years; 72% women) were assigned to the physical activity (N = 151) or healthy education control (N = 156) groups. Interventions were led by study staff for the first 6 months and sustained by peer leaders for the next 6 months. Components included individual counseling and self-monitoring with pedometers, group education sessions, and printed materials. Measurements occurred at baseline, 6 months, and 12 months. Triaxial accelerometers measured physical activity for 1 week. The Trail Making Test (TMT) Parts A and B and a Symbol Search Test measured cognitive functions. Results There were no significant differences in cognitive functions between the MIPARC intervention and control groups at 6 or 12 months. Within-person increases in MVPA, and not low-light or high-light physical activity, were associated with improvements in TMT Parts B, B-A, and Symbol Search scores in the entire sample. Conclusion Findings suggest that MVPA may have a stronger impact on cognitive functions than lower intensity physical activity within Retirement community samples of highly educated older adults without dementia.

  • assessing psychometric properties of the promis sleep disturbance scale in older adults in independent living and continuing care Retirement Communities
    Sleep Health, 2019
    Co-Authors: Katie Crist, Kelsie M Full, Atul Malhotra, Kevin Moran, Jacqueline Kerr
    Abstract:

    Abstract Purpose Sleep disturbances are associated with poor health outcomes in older adults. The Patient-Reported Outcomes Information System (PROMIS) Sleep Disturbance Scale was designed to assess self-reported general sleep and sleep disturbance. The objective of this study was to validate the short-form PROMIS Sleep Disturbance Scale for use among older adults living in independent-living and continuing care Retirement Communities. Methods Older adults (N = 307) were recruited from Retirement Communities in San Diego, CA, to participate in a physical activity intervention. Study participants were on average 83.6 years (SD 6.4) and predominately female (72.3%). Self-reported health outcomes included sleep disturbance, depressive symptoms, quality of life, stress, and pain. Internal consistency of the PROMIS Sleep Disturbance Scale was determined using Cronbach α, individual item means, and interitem correlations. Construct validity was examined using exploratory factor analysis techniques. Adjusted linear regression models assessed the predictive validity of the Sleep Disturbance Scale and associations with health outcomes. Results The PROMIS Sleep Disturbance Scale had a Cronbach α = .856 and an interitem correlation of .504. All items loaded on 1 sole factor. Additionally, the sleep scale was significantly predictive of depressive symptoms, stress, and quality of life at 12 months. Conclusions The PROMIS 6-item Sleep Disturbance Scale had acceptable internal consistency and strong construct validity among a sample of elderly older adults in an independent-living community setting. These findings suggest that the PROMIS scale may provide an accurate assessment of sleep disturbance in older adults. Additional validation testing using objective measures of sleep is needed to confirm these findings further.

Patterns of sedentary time accumulation may vary and have differential health risks. The purpose of this study is to describe sedentary patterns of older adults living in Retirement Communities and illustrate gender and age differences in those patterns.MethodsBaseline accelerometer data from 307 men and women (mean age = 84±6 years) who wore ActiGraph GT3X+ accelerometers for ≥ 4 days as part of a physical activity intervention were classified into bouts of sedentary time (l100 counts per minute). Linear mixed models were used to account for intra-person and site-level clustering. Daily and hourly summaries were examined in mutually non-exclusive bouts of sedentary time that were 1+, 5+, 10+, 20+, 30+, 40+, 50+, 60+, 90+ and 120+ minutes in duration. Variations by time of day, age and gender were explored.ResultsMen accumulated more sedentary time than women in 1+, 5+, 10+, 20+, 30+, 40+, 50+ and 60+ minute bouts; the largest gender-differences were observed in 10+ and 20+ minute bouts. Age was positively associated with sedentary time, but only in bouts of 10+, 20+, 30+, and 40+ minutes. Women had more daily 1+ minute sedentary bouts than men (71.8 vs. 65.2), indicating they break up sedentary time more often. For men and women, a greater proportion of time was spent being sedentary during later hours of the day than earlier. Gender differences in intra-day sedentary time were observed during morning hours with women accumulating less sedentary time overall and having more 1+ minute bouts.ConclusionsPatterns identified using bouts of sedentary time revealed gender and age differences in the way in which sedentary time was accumulated by older adults in Retirement Communities. Awareness of these patterns can help interventionists better target sedentary time and may aid in the identification of health risks associated with sedentary behavior. Future studies should investigate the impact of patterns of sedentary time on healthy aging, disease, and mortality.

  • applying the ecological model of behavior change to a physical activity trial in Retirement Communities description of the study protocol
    Contemporary Clinical Trials, 2012
    Co-Authors: Jacqueline Kerr, Dori E Rosenberg, Katie Crist, Andrea Nathan, Rachel A Millstein, Jordan A Carlson, Kari Wasilenko, Khalisa Bolling, Cynthia M Castro, David M Buchner
    Abstract:

    Objectives To describe the intervention protocol for the first multilevel ecological intervention for physical activity in Retirement Communities that addresses individual, interpersonal and community influences on behavior change. Design A cluster randomized controlled trial design was employed with two study arms: a physical activity intervention and an attention control successful aging condition. Setting Sixteen continuing care Retirement Communities in San Diego County. Participants Three hundred twenty older adults, aged 65 years and older, are being recruited to participate in the trial. In addition, peer leaders are being recruited to lead some study activities, especially to sustain the intervention after study activities ceased. Intervention Participants in the physical activity trial receive individual, interpersonal and community intervention components. The individual level components include pedometers, goal setting and individual phone counseling. The interpersonal level components include group education sessions and peer-led activities. The community level components include resource audits and enumeration, tailored walking maps, and community improvement projects. The successful aging group receives individual and group attention about successful aging topics. Measurements The main outcome is light to moderate physical activity, measured objectively by accelerometry. Other objective outcomes included physical functioning, blood pressure, physical fitness, and cognitive functioning. Self report measures include depressive symptoms and health related quality of life. Results The intervention is being delivered successfully in the Communities and compliance rates are high. Conclusion Ecological Models call for interventions that address multiple levels of the model. Previous studies have not included components at each level and Retirement Communities provide a model environment to demonstrate how to implement such an intervention.
