How Do Discrepancies between Subjective and Objective Health Predict the Risk of Injurious Falls? A Study of Community-Dwelling Swedish Older Adults.

OBJECTIVES: Previous studies demonstrated that discrepancies between subjective and objective health measures are associated with physical and mental health-related outcomes in older adults. We investigate whether such discrepancies are also associated with risk of injurious falls in community-dwelling Swedish older adults. DESIGN: A prospective, observational cohort study. SETTING AND PARTICIPANTS: Using data from the Swedish National Study on Aging and Care in Kungsholmen, we followed 2222 community-dwelling older adults aged ≥60 years at baseline, across a 10-year period of data collection (2001-2011). METHODS: A "health asymmetry" metric classified older adults into 4 categories, based on the level of agreement between their subjective and objective health scores ("health pessimist", "health optimist", "poor health realist", and "good health realist"). Time-varying Cox proportional hazard and Laplace regressions were employed to investigate if these categories were associated with the risk of injurious falls. RESULTS: Over a 10-year follow-up, 23.5% of the sample experienced an injurious fall. Health optimists had the greatest risk of experiencing an injurious fall [hazard ratio (HR) 2.16, 95% confidence interval (CI) 1.66, 2.80], compared with good health realists. Poor health realists (HR 1.77, 95% CI 1.50, 2.11) and health pessimists (HR 1.66, 95% CI 1.21, 2.29) also had an increased risk of experiencing injurious falls, compared with good health realists. Being a health pessimist was only associated with the risk of injurious falls within the younger-old (HR 2.43, 95% CI 1.63, 3.64) and among males (HR 1.95, 95% CI 1.14, 3.33). CONCLUSIONS AND IMPLICATIONS: Older adults with similar objective health levels may differ in terms of their injurious fall risk, depending on their subjective health. Interpreting subjective health alongside objective health is clinically pertinent when assessing injurious fall risk.

Procrastination, depressive symptomatology, and loneliness in later life.

OBJECTIVES: Procrastination is an almost universal behaviour and yet little research to date has focused on procrastination among older adults. The purpose of this study was to explore the potential association between age and procrastination, and the potential mediating roles of depressive symptomatology and loneliness. METHOD: Structural equation modelling was applied to data from 1309 participants (aged 29-92) from two waves United States Health and Retirement Study (2016-2020). Within the model, sex, education, marital status, and job status were added as covariates. RESULTS: There was no statistically significant direct effect between age and procrastination (ß = 0.06, p = 0.106). However, an indirect effect was present via depressive symptomatology (ß = -0.40, p < 0.001). No mediating effect of loneliness was observed (ß = - 0.01, p = 0.371). Subsequent analysis revealed that the symptoms, fatigue, loneliness, and lack of motivation significantly predicted procrastination. CONCLUSION: While age was not directly associated with procrastination, increasing age was associated with a decreased likelihood of depressive symptomatology, which was in turn associated with an increased likelihood of procrastination. Such findings indicates that age demonstrates no association with procrastination because of the suppressing effect of depressive symptomatology.

Support for the Supporter: Paternal Postpartum Loneliness and Social Support During the COVID-19 Pandemic.

During the postpartum period, fathers may be at risk of increased stress and loneliness, which may be offset or buffered by the provision of social support. This study aimed to explore fathers' postpartum experiences of loneliness, perceived stress, and social support. A constructivist grounded theory approach was used to inform study design and analysis. Semistructured interviews were conducted to collect data from 12 fathers, living in the Republic of Ireland, who had an infant aged 6 months or younger. A grounded theory entitled "support for the supporter," describing fathers' experiences with social support, and loneliness during the postpartum period, was derived. Participants described experiencing increased financial pressure and having difficulty balancing the role of "breadwinner" with fatherhood. Participants described feeling excluded from maternity care and lacked avenues for information within the Irish health care system. Participants linked their experiences of loneliness to the lack of social support in the postpartum period. This study offers a novel insight into Irish fathers' experiences with maternity care during the COVID-19 pandemic. This study is the first to qualitatively explore paternal postpartum loneliness and provides a good foundation for future research and intervention in this area. Findings suggest that it would be wise to promote social support from other experienced fathers, friends, family, and from partners to reduce paternal postpartum loneliness.

Mechanisms through which befriending services may impact the health of older adults: A dyadic qualitative investigation.

Befriending services are often delivered to older adults with a view to improving social connectedness, but they may also lead to improved health. The objective of the current study was to explore potential mechanisms through which befriending services might impact the health of older adults. Data were collected from 13 befriendee-befriender dyads (n = 26), using a constructivist grounded theory and dyadic analytic approach. Potential mechanisms were described, using a realist evaluative framework of mechanistic processes in a complex intervention context. Five mechanisms of action triggered by the intervention were identified: supporting health behaviours; providing emotional support; improving mood; getting cognitive stimulation and novelty; and providing opportunities for socialising. We identified five potential mechanisms through which befriending services might impact health for older people. Our results suggest potential mechanisms through which befriending might positively impact the health of older people, and which should be evaluated empirically in future research.

Guidelines for evaluating and reporting social isolation and loneliness interventions.

Given the unpleasant nature of social isolation and loneliness (SIL) and their negative effects on health and wellbeing, interventions are needed. However, persistent issues in the design, evaluation, and reporting of SIL interventions preclude conclusive evidence and commentary on the effectiveness of SIL interventions. Here, we propose guidelines for evaluating SIL interventions, firstly by operationalising them into two categories: (1) interventions aiming to reduce SIL as a primary outcome and (2) interventions aiming to improve non-SIL outcomes in the lives of individuals experiencing SIL. Secondly, we evaluate instruments for measuring SIL and research designs for studying intervention effectiveness. Thirdly, guidelines for reporting information about the intervention, study design, results, and discussion in SIL intervention studies are presented. These guidelines will help researchers to better and more consistently report on SIL interventions and improve comparability of SIL interventions, ultimately contributing to the improvement of interventions and to the mitigation of SIL.

Freedom and loneliness: dementia caregiver experiences of the nursing home transition.

BACKGROUND: the transition to nursing home care has previously been linked to negative outcomes for spousal caregivers of persons with dementia (PwD). However, little is known about the experience or trajectory of loneliness in spousal caregivers during this time. OBJECTIVES: to explore experiences of loneliness in caregivers during the nursing home admission of their spouse or partner with dementia. METHODS: semi-structured interviews were conducted with 11 individuals living in Ireland between Oct 2020 and June 2021, who were married to/partnered with a PwD who had, in the past 7 years, moved to full-time nursing home care. Data were collected and analysed using a deductive qualitative analytic strategy in the grounded theory tradition. RESULTS: data were interpreted in the context of Weiss' typology of social and emotional loneliness and indicated that social loneliness increased for many at the point of diagnosis, decreasing somewhat after the transition, while emotional loneliness increased across the transition. Data were used to refine an existing synthesised model of loneliness, providing an updated model of the causes and contexts of loneliness. CONCLUSIONS: the transition to nursing home care differentially affects loneliness subtypes. Results have implications for other transitions, which should be assessed in terms of various subtypes of loneliness. Our refined theoretical synthesis model of loneliness also warrants further evaluation.

Health asymmetry as a predictor of depressive symptomatology over time among older European adults: A growth curve analysis.

OBJECTIVE: Subjective (SH) and objective health (OH) measures are associated with depressive symptomatology in older adults. We explored whether the discrepancy between SH and OH (operationalised as 'health asymmetry' with four categories: 'health optimistic', 'health pessimistic' and 'good health realistic' and 'poor health realistic') may also relate to depressive symptomatology 1) cross-sectionally, and 2) longitudinally, among older European adults. METHODS: Adults (n = 26,520), aged 50+, from 11 European countries, were assessed over six waves of data collection (2006-2020) in the SHARE study. A hierarchical multi-level growth curve model explored whether health asymmetry was associated with depressive symptomology at baseline, and with depressive symptom trajectories across time, accounting for country of origin. RESULTS: At baseline, 11.8% of older adults were classified as health pessimistic, with 15.5% being health optimistic, 42.9% being poor health realistic and 29.8% being good health realistic. A positive linear trend in depressive symptomatology was noted across 14 years of SHARE data (ß = 0.11, p < .001). Health pessimists displayed higher levels of depressive symptoms than both health realistic groups and health optimists. However, health pessimists experienced a less steep increase in depressive symptoms across time (ß = -0.10, p < .001), relative to good health realists. CONCLUSION: Health pessimists experience elevated levels of depressive symptoms, but show less growth in depressive symptomatology than expected. Further research is required to understand the underlying causes of the varying depressive symptom trajectories among these groups.

Exposure to the troubles in Northern Ireland, memory functioning, and social activity engagement: results from NICOLA.

We investigated the potential impact of a cohort traumatic exposure, the Troubles in Northern Ireland, on memory functioning in later life, and the potential moderating effect of social activity engagement. Using data from 6571 participants aged 60 + in the Northern Ireland Cohort for the Longitudinal Study of Ageing (NICOLA) cohort, we used a structural equation modelling framework to explore associations between traumatic exposure during the Troubles and memory functioning. As expected, social activity engagement was positively associated with memory functioning, ß = .102. Traumatic exposure was also positively associated with memory functioning, ß = .053. This association was stronger at low levels of social activity engagement; among those with higher levels, there was little association, interaction ß = - 0.054. The positive association between traumatic exposure during the Troubles and memory functioning was not moderated by the age at which the exposures occurred (based on analysis of a subsample with available data), interaction ß = - 0.015. We conclude that superior memory functioning was associated with higher levels of traumatic exposure during the Troubles, particularly among those with lower levels of social activity engagement, and regardless of the age at which the exposures occurred. Future longitudinal analyses are required to build on these results, which potentially have implications for life-course epidemiology, in relation to critical periods for traumatising experiences.

Expecting the best or fearing the worst: Discrepancies between self-rated health and frailty in an ageing Irish population.

OBJECTIVES: Ageing populations have the propensity to rate their health status more inaccurately than their younger counterparts. As a result, we (1) devised a metric which categorized older adults into groups based on the discrepancy between their self-rated health (SRH) and Frailty Index (FI) scores, and (2) investigated which factors predict group membership. DESIGN: A cross-sectional design was employed using data from The Irish Longitudinal Study of Ageing (TILDA). METHODS: A health asymmetry metric was derived: this categorized 6907 participants (aged 50+ years) into three groups: 'health pessimistic' where participants underestimated their healthiness, 'health realistic' where participants accurately assessed their health, and 'health optimistic' where participants overestimated their healthiness. A multinomial logistic regression modelled the ability of a set of sociodemographic, psychosocial, and health behaviour variables in predicting membership of these categories. RESULTS: A significant proportion of the study population were categorized as 'health realistic' (~69%). The prevalence rates of health optimistic individuals increased in older age groups, and conversely, health pessimistic rates decreased in older age groups. Most notably, psychosocial factors significantly predicted being health pessimistic: such as anxiety (OR = 1.03), loneliness (OR = 1.04), and decreased social connectedness (OR = 0.87). However, less clear sociodemographic, psychosocial, and health behaviour associations were found for being health optimistic. CONCLUSION: Health asymmetry is a useful method of identifying at-risk individuals for inaccurate SRH. The ability of this metric to predict clinical mental health outcomes should be investigated.

Posttraumatic stress disorder, complex PTSD and subtypes of loneliness among older adults.

OBJECTIVES: Research examining the relationship between loneliness and Complex Posttraumatic Stress Disorder (CPTSD) is scarce, particularly among older adults. CPTSD includes the core symptoms of PTSD along with additional symptoms reflecting "disturbances in self-organisation" (DSO). This study examined the cross-sectional relationships between loneliness (emotional and social loneliness) and CPTSD symptoms (i.e., PTSD and DSO symptoms) in older adults. METHODS: Structural equation modelling was used to examine these relationships in a nationally representative sample of US adults aged 60-70 years (n = 456). RESULTS: Controlling for covariates, emotional loneliness was associated with PTSD (ß = 0.31) and DSO (ß = 0.57) symptoms whereas social loneliness was only associated with DSO symptoms (ß = 0.25). The model explained 35.0% of the variance in PTSD symptoms and 71.3% in DSO symptoms. CONCLUSION: These findings have important implications for treating and understanding PTSD/CPTSD and their correlates among older adults.

Social isolation, social support and loneliness as independent concepts, and their relationship with health-related quality of life among older women.

Objectives: To assess whether social isolation, social support, and loneliness are independently associated with health-related quality of life (HRQoL).Method: Retrospective analysis including 10,517 women aged 70-75 years from the Australian Longitudinal Study on Women's Health (ALSWH). Social isolation, social support (Duke Social Support Index), and loneliness (single item) were investigated for their association with standardised HRQoL (physical [PCS] and mental [MCS] components of the SF-36® questionnaire). Analyses were adjusted for sociodemographic variables and number of medical conditions.Results: Only 3% reported being socially isolated, having low social support and being lonely, and 34% reported being not socially isolated, high social support and not being lonely. Each construct was independently associated with HRQoL, with loneliness having the strongest inverse association (PCS: isolation -0.98, low support -2.01, loneliness -2.03; MCS: isolation -1.97, low support -4.79, loneliness -10.20; p-value < 0.001 for each). Women who were not isolated or lonely and with high social support had the greatest HRQoL (compared to isolated, low social support and lonely; MCS: 17 to 18 points higher, PCS: 5 to 8 points higher). Other combinations of social isolation, social support and loneliness varied in their associations with HRQoL.Conclusion: Ageing populations face the challenge of supporting older people to maintain longer, healthy, meaningful and community-dwelling lives. Among older women, social isolation, low social support and loneliness are distinct, partially overlapping yet interconnected concepts that coexist and are each adversely associated with HRQoL. Findings should be replicated in other cohorts to ensure generalisability across other age groups and men.

Social isolation, social support, and loneliness and their relationship with cognitive health and dementia.

BACKGROUND: Poor social health is prevalent in older adults and may be associated with worse cognition, and increased dementia risk. The aim of this study was to determine whether social isolation, social support and loneliness are independently associated with cognitive function and incident dementia over 5 years in older adults, and to investigate potential gender differences. METHODS: Participants were 11,498 community-dwelling relatively healthy Australians aged 70-94, in the ASPREE Longitudinal Study of Older Persons (ALSOP). Social isolation, social support, loneliness and cognitive function were assessed through self-report. Outcomes examined were cognitive decline (>1.5 SD decline in cognitive performance since baseline) and incident dementia (adjudicated according to DSM-IV criteria). RESULTS: Most participants self-reported good social health (92%) with very few socially isolated (2%), with low social support (2%) or lonely (5%). Among women, social isolation and low social support were consistently associated with lower cognitive function (e.g., social support and cognition ß = -1.17, p < 0.001). No consistent longitudinal associations were observed between baseline social health and cognitive decline (over median 3.1 years) or incident dementia (over median 4.4 years; social isolation: HR = 1.00, p = 0.99; low social support: HR = 1.79, p = 0.11; loneliness: HR = 0.72, p = 0.34 among women and men). CONCLUSION: Our study provides evidence that social isolation and a low social support are associated with worse cognitive function in women, but not men. Social health did not predict incident cognitive decline or dementia, but we lacked power to stratify dementia analyses by gender.

Older Users of a Befriending Service in Ireland and the Maintenance of Personal Autonomy during the COVID-19 Pandemic.

In the Republic of Ireland (RoI), COVID-19 public health guidelines have been most restrictive for people aged 70 and over. Such individuals are most likely to avail of befriending services offered by a network of Irish organisations. The aim of this study was to explore the impact of COVID-19 guidelines on befriending service users, and to develop recommended adaptations to befriending services compatible with such guidelines. A qualitative constructivist grounded theory approach was taken to the study design and analysis, using semi-structured interviews to collect data from 11 participants by telephone between May 2020 and January 2021. Results show a grounded theory describing how older users of a befriending service maintained their personal autonomy in the face of strict government guidelines. Participants described living life as usual, often contravening guidelines, and how they chose to adapt to the situation, yielding both positive and negative outcomes. Some potential adaptations were discussed to the befriending service (including a preserved focus on the social and emotional functions of the befriending relationship, and the accommodation of collaborative decision making about communicative alternatives), but ultimately it was made clear that participants would tailor the services to their own preferences. Results have implications for befriending service design and delivery, and for public health officials who wish to support the health of older adults during the COVID-19 pandemic.

Posttraumatic stress disorder and loneliness are associated over time: A longitudinal study on PTSD symptoms and loneliness, among older adults.

Loneliness has a pernicious effect on mental health in later life and is likely to have a bidirectional relationship with psychopathology. However, longitudinal research examining loneliness and posttraumatic stress symptoms among older adults is scarce. This study aimed to examine the longitudinal relationship between different types of loneliness (social and emotional) and posttraumatic stress symptoms. Using two waves of an older adult sample (n = 1,276) from the Longitudinal Aging Study Amsterdam (LASA), this longitudinal relationship was examined using a multivariate two wave-latent change score (2W-LCS) model. There were significant, however, very small increases in both posttraumatic stress symptoms and emotional loneliness over time, whereas, average social loneliness scores did not significantly increase/decrease over time. Changes in both social (ß = .16) and emotional loneliness (ß = .15) were associated with small changes in posttraumatic stress symptoms, consistent with the existence of a longitudinal association between the constructs, net of covariate effects. Results provide evidence of the existence of a longitudinal association between subtypes of loneliness and posttraumatic stress symptoms, among older adults. Results have implications for clinicians who should identify individuals at risk of developing posttraumatic stress symptoms, and for the theory of both posttraumatic stress disorder and loneliness.

Clustering of Behavioral Changes and Their Associations With Cognitive Decline in Older Adults.

OBJECTIVES: To examine (1) the clustering of reduced falls-efficacy, social withdrawal, and physical activity withdrawal in Irish adults aged 50 years and older, and (2) the concurrent and prospective associations of these clustered behaviors with cognitive decline. DESIGN: Longitudinal cohort study. SETTING AND PARTICIPANTS: Data were from 4571 participants (mean age 64.5 ± 8.6, 54.9% women) in The Irish Longitudinal Study on Ageing, a population-based study. METHODS: Changes in social and physical activity and falls-efficacy from 2012/2013 to 2014/2015 were used to define the behaviors of social withdrawal, physical activity withdrawal, and reduced falls-efficacy. Patterns of behaviors were associated with concurrent (2012/2013-2014/2015) and prospective (2014/2015-2016/2017) changes in immediate recall, delayed recall, and verbal fluency using random effects mixed models. RESULTS: Eighty-six percent of participants had social withdrawal, physical activity withdrawal, or reduced falls-efficacy, and 15% had all 3 behaviors. Participants with all 3 behaviors showed the greatest declines in immediate recall (concurrent: B = -0.51, confidence interval [CI] = -0.77 to -0.25; prospective: B = -0.51, CI = -0.78 to -0.25), delayed recall (concurrent: B = -0.40, CI = -0.61 to -0.18; prospective: B = -0.47, CI = -0.69 to -0.25) and verbal fluency (concurrent: B = -1.05, CI = -1.58 to -0.52; prospective: B = -1.29, CI = -1.83 to -0.74). CONCLUSIONS AND IMPLICATIONS: The clustering of social withdrawal, physical activity withdrawal, and reduced falls-efficacy is common. Presence of multiple behaviors was associated with greater cognitive declines, suggesting a cumulative association of these behaviors with cognitive decline. These findings guide (1) identification of vulnerable groups, (2) intervention design, and (3) care planning for people presenting with 1 or more of these changes in behavior.

Patterns of comorbidity associated with ICD-11 PTSD among older adults in the United States.

Little research has been conducted on posttraumatic stress disorder (PTSD) comorbidity among older adults regarding the description of PTSD in the 11th version of the International Classification of Diseases (ICD-11). This study sought to provide evidence of a dimensional model of psychopathology using the 'Hierarchical Taxonomy of Psychopathology' (HiTOP) model as a theoretical framework to explain patterns of ICD-11 PTSD comorbidity. Distinct patterns of ICD-11 PTSD comorbidity among a nationally representative sample (n = 530) of adults aged 60 years and older from the United States were examined using latent class analysis (LCA). Covariates associated with comorbidity classes were assessed through multinomial logistic regression. ICD-11 PTSD was highly comorbid with other psychopathologies. LCA results favoured a two-class solution. Class 1 (71.7%) was characterised by moderate probabilities for major depressive disorder and alcohol use disorder; Class 2 (28.3%) was characterised by a moderate-high probability of general psychopathology and was associated with lower social support, spousal/partner physical abuse, and history of attempted suicide. PTSD was highly comorbid with other disorders among older adults. Distinct patterns of PTSD comorbidity exist among this cohort and these findings can aid clinicians and researchers in understanding and predicting maladaptive responses to trauma and associated psychopathology.

Posttraumatic stress disorder among older adults: A differential item functioning analysis of PTSD in ICD-11 and DSM-5.

OBJECTIVE: Distinct models of posttraumatic stress disorder (PTSD) are outlined in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the 11th version of the International Classification of Diseases (ICD-11). Limited data exists about the validity of these models among older adults. This study examines the probable prevalence rates of PTSD in older adults; the factorial validity of both models; and symptom-endorsement bias across sex. METHOD: Using a nationally representative (United States) sample (n = 5,366) of older adults aged 60 years and older, alternative PTSD factor models were tested using confirmatory factor analysis (CFA), and item bias was assessed using differential item functioning (DIF) analysis. PTSD was measured without the functional impairment criterion, likely resulting in inflated prevalence rates. RESULTS: DSM-5 (9.5%) PTSD prevalence was significantly higher than ICD-11 (8.7%). Women were more likely to meet criteria for DSM-5 (OR = 1.79) and ICD-11 (OR = 1.38) PTSD. CFA results showed that both models of PTSD had excellent fit. Four DSM-5 symptoms demonstrated DIF, with females more likely to endorse three symptoms (B1: "unwanted memories"; B4: "feeling upset"; and E6: "sleep problems") and males more likely to endorse one symptom (E2: "reckless or self-destructive behavior"). No DIF was present for the 6 ICD-11 symptoms. CONCLUSION: Both PTSD models perform well among older adults, although there is evidence of DIF in the DSM-5 model. A considerable proportion of older adults met diagnostic requirements for PTSD, thus highlighting the importance of trauma-related research among older adult populations.

HALO: Study protocol for a single-case experimental design study evaluating the moderating impact of a befriending intervention on the association between loneliness and health in older adults.

Background: Loneliness in later life is often addressed with befriending interventions, yet evidence for their effectiveness is limited. Meanwhile it is known that loneliness has a deleterious impact on health. The aim of the study is to evaluate whether a befriending service for older adults mitigates the impact of loneliness on health outcomes, and to identify mechanisms through which befriending interventions might impact upon health. Methods: A mixed methods design is used. The quantitative component utilises an AB single-case experimental design, to gather intensive longitudinal data. These data will be analysed using a generalised additive modelling approach. The qualitative component of the study uses semi-structured dyadic interviews, structured and analysed according to the principles of constructivist grounded theory. Findings will then be triangulated according to an existing mixed methods integration protocol. Discussion: This mixed methods design has the potential to inform national and international policy in relation to befriending interventions for older adults. In addition, there is the potential for study results to inform our theoretical understanding of the nature of the relationship between loneliness and health.
