Social support as a predictor of variability: An examination of the adjustment trajectories of recent widows

Affect variability and cortisol in context: The moderating roles of mean affect and stress

Positive and negative affect have been shown to have implications for hormones like cortisol but how moment to moment changes in affect (i.e., affect variability) influence cortisol secretion is less well understood. Additionally, context characteristics such as mean affect and stress may influence the association between affect variability and cortisol output. In the current study, we examined affect, stress, and cortisol data from 113 participants (age range = 25-63, M = 35.63, SD = 11.34; 29% male; 42% White/Caucasian, 37% Asian or Pacific Islander, 13% Hispanic/Latino, 4% Black/African American, 1% Native American, Eskimo, or Aleut, 4% selected "other" for their race/ethnicity). Participants completed ecological momentary assessments assessing positive and negative affect and stress four times per day for five days and provided saliva samples at each time point. Saliva was assayed for cortisol, and area under the curve with respect to ground was computed. In a three-way interaction, both positive affect mean level and stress moderated the association between positive affect variability and cortisol (b = -1.55, t(100) = -3.29, SE = 0.47, p <.01, β = -4.05). When breaking down this three-way interaction, in the context of low stress and high mean positive affect, variability was positively related to total cortisol output. In contrast, in the context of high stress and high mean positive affect, variability was negatively related to total cortisol output. While greater positive affect variability is generally worse for health-relevant outcomes (as prior research has shown and as we show here at low levels of stress), at high levels of stress, fluctuation in affect may be adaptive. For someone experiencing a high stress week, having fluctuations in positive affect may mean that they are adaptively changing to meet their environmental needs especially when they typically report high mean positive affect levels. There were no associations between negative affect variability and cortisol secretion nor did mean negative affect or stress play a moderating role for negative affect variability. This study provides evidence that positive affect variability's association with cortisol secretion throughout the day may vary based on stress and mean positive affect levels.

Journey Towards a Meaningful Life: Adaptation and Resilience in the Lives of Young Hindu Widows

Spousal death is a life-altering and traumatic life event in married life, compelling the surviving partner to transition and make substantial adjustments to their new life situation. Losing a spouse can affect individuals differently based on gender, impacting their psychological, social, and economic well-being. This article describes adaptation to a new life condition as widows strive to reconcile their roles, status, and identity while binding their resilience to direct their lives. This study explored the lives of 17 young Hindu widows in rural and semi-urban areas of Haryana, India. Using personal face-to-face interviews and purposive sampling, it captured their unique life stories. After losing their spouses, participants showed impressive resilience, reshaping their lives and identities. They navigated challenges firmly, emphasising personal commitment over social support for effective adaptation. It highlights a need for better support systems for widows, offering potential pathways to enhance their post-loss well-being.

Potential factors associated with resilience among older adults in rural China: a multilevel analysis

BACKGROUND

Resilience is crucial for older adults who experience adversities, but research on the issue in rural China remains limited. This study aims to examine factors associated with resilience among older adults in rural China, as related to different types of resilience, and under different levels of adversity.

METHODS

Data were taken from the eight-wave (2001-2021) Longitudinal Study of Older Adults in Anhui Province, China. We used data from the eighth wave (2021) for the outcome variables and lagged predictors (2018) to avoid reverse causal effects. The study sample included individuals 60 years and above, excluding new participants from 2021, those without any adverse events, and any respondents with incomplete analytic data. Resilience was operationalized as residuals of the regressions of life satisfaction (Life Satisfaction Scale) and depressive symptoms (CES-D) on adversity, referred to as Type-1 and Type-2 resilience respectively. These two types of resilience were then treated as the outcome variables in subsequent multilevel regressions, with the predictors focusing on individual, social, and environmental characteristics and resources. This study adheres to STROBE guidelines.

RESULTS

43% of rural older adults exhibited both Type-1 and Type-2 resilience, whereas 18% exhibited only Type-1 resilience and 7% exhibited only Type-2 resilience. Common factors associated with both types of resilience included self-rated health, satisfaction with one's own financial situation, and the prestigiousness of social networks. Predictors for higher levels of Type-1 resilience included higher levels of financial and emotional support and more options for places of leisure. Predictors for higher levels of Type-2 resilience included greater access to medical care. The prestigiousness of social networks, higher levels of emotional support and instrumental support, access to medical care, and more options of places of leisure were positively associated with resilience in the low-adversity group (first tertile of adversity), only satisfaction with financial situation was positively correlated with the resilience of the middle-adversity group (second tertile), while better self-rated health, satisfaction with financial situation, and financial support yielded greater resilience in the high-adversity group (third tertile).

CONCLUSIONS

We examined two types of resilience among older adults in rural China, and found that they have shared and unique associated factors. In addition, the potential factors influencing resilience varied with the level of adversity.

Separating Long-Term Equilibrium Adaptation from Short-Term Self-Regulation Dynamics Using Latent Differential Equations

Self-regulating systems change along different timescales. Within a given week, a depressed person's affect might oscillate around a low equilibrium point. However, when the timeframe is expanded to capture the year during which they onboarded antidepressant medication, their equilibrium and oscillatory patterns might reorganize around a higher affective point. To simultaneously account for the meaningful change processes that happen at different time scales in complex self-regulatory systems, we propose a single model that combines a second-order linear differential equation for short timescale regulation and a first-order linear differential equation for long timescale adaptation of equilibrium. This model allows for individual-level moderation of short-timescale model parameters. The model is tested in a simulation study which shows that, surprisingly, the short and long timescales can fully overlap and the model still converges to the reasonable estimates. Finally, an application of this model to self-regulation of emotional well-being in recent widows is presented and discussed.

Trajectories of Instrumental and Emotional Social Support and the Associated Risk of Mortality in Bereaved Older Adults in Taiwan

This study identified the trajectories of instrumental and emotional perceived social support (PSS) from 1996 to 2003 and investigated the associated risk of mortality in bereaved older adults in Taiwan. The study analyzed 1,188 bereaved older adults who had experienced loss of a spouse, a child, or both before 1996 from the Taiwan Longitudinal Study on Aging. More favorable trajectories of PSS are associated with lower mortality risk in bereaved older adults. Compared with the spousal or dual bereavement, the parental bereavement benefited more from consistently high instrumental PSS. The present study revealed that consistently high emotional PSS had a stronger protective effect on mortality risk for a widow or widower than did consistently high instrumental support. The findings of this study can serve as an empirical reference to inform social policies and clinical practices for bereaved older adults in culturally similar societies.

Social participation in widowhood: Evidence from a 12-year panel

OBJECTIVES

Social participation is important to the quality of life of older adults, especially widows. This is the first study to test whether older widows' formal and informal social participation rises or declines using multiple panel observations pre- and post-bereavement. The paper also tests the moderating effects of economic and marital satisfaction, depression, and husband's illness before death on these trends.

METHODS

Seven waves of the Korean Longitudinal Study of Ageing are used to track changes in four measures of social participation - meeting and contacting a child, meeting friends, and attending a formal group. A comparison group of married individuals, weighted with coarsened exact matching, controls for age and time trends. Mixed model regressions estimate the effects of widowhood over time.

RESULTS

Social participation shows little change before bereavement and rises significantly after bereavement for all measures. However, frequencies of meeting and contacting a child peak and decline early post-bereavement, while meeting friends and attending a group show delayed but long-lasting effects. Moderators economic and marital satisfaction are positively associated with overall social participation levels, but negatively associated with social participation post-bereavement.

DISCUSSION

Increased social participation after bereavement underscores the resilience of widows and the social support they receive. However, differences in timing suggest that contact with children is gradually substituted with extra-familial relationships in the long run. The negative moderating roles of economic and marital satisfaction point to a paradox where seemingly well-off individuals may be more vulnerable to widowhood.

Dynamic Systems, Contextual Influences, and Multiple Timescales: Emotion Regulation as a Resilience Resource

We need to understand how psychosocial resources develop, identify the influences that threaten their maintenance, detect the circumstances under which these resources are used, and elucidate the factors that support and promote their growth. Three important components to studying the development of resilience include its dynamic nature, context, and timescale of measurement. Dynamic systems (DS) approaches focus on physiological and psychological structures underling the development of resilience by explicitly mapping parameters of change onto their corresponding aspects of functioning. Previous research has captured emotion regulation within individuals, across traits, and in close personal relationships to show how these methods depict dynamic regulation/resilience resources and their influence on outcomes of interest. The use of multi-time scaled data informs how daily emotion regulation is disrupted in the context of stress to produce dysregulation and disease later in the life course. This approach can also reveal how resilience resources counteract these adverse processes and allow others to thrive and be well. Researchers must not only explore short-term variation in constructs of interest, but also explore how these shorter-term fluctuations contribute to longer-term changes. The confluence of DS, contextual influences, and multiple timescales provides an important set of tools to better understand development.

Daily stress reactivity: The unique roles of personality and social support

BACKGROUND

The processes through which social support exerts its influence in daily life are not well understood. Arguably, its salutary effects as an environmental variable might be construed as shared effects of personality.

METHOD

To test this possibility, we investigated the unique and shared effects of personality and social support on daily stressor exposure (social conflict, task strain) and on the within-person association of stressor exposure with perceived stress. A community-sample of N = 391 adults completed an ambulatory assessment protocol for two 2-day periods with fixed hourly intervals spread across 16 hr.

RESULTS

Consistent with our preregistered hypotheses, multilevel structural equation models returned that both, personality and perceived social support, predicted daily stressor exposure and moderated within-person effects of daily stressors on perceived stress. In contrast to our hypotheses, received social support had no effect on daily stress processes. When Extraversion, Neuroticism, and social support were added as joint predictors, Neuroticism and Extraversion were related to stressor exposure, and further moderated the within-person link between stressor exposure and stress experience, while perceived social support had an incremental beneficial effect on social conflict exposure and stress appraisal.

CONCLUSION

Social support does not increment the well-established relationships between Neuroticism or Extraversion and stress reactivity.

Trajectories of resilience among widows: a latent transition model

OBJECTIVES

In 2015 we identified three profiles of adaptation following spousal bereavement: Vulnerables; Copers and Resilients (Spahni, Morselli, Perrig-Chiello, & Bennett, 2015). However, adaptation to spousal bereavement is a dynamic process. Thus, we examine the trajectories of the same participants longitudinally over two years. We identify the stability and change in profiles of adaptation to widowhood; probability of stability and change; factors that influence trajectories in profile membership.

METHODS

Data stem from a longitudinal questionnaire study of 309 older widowed people. The questionnaire included five measures of well-being, serving as the dependent variables of this analysis, and measures of personal resources and contextual factors, including social support, marital happiness, psychological resilience, and demography. Data was analysed using latent transition analysis of the variables loneliness, hopelessness, depressive symptoms, life satisfaction, and subjective health.

RESULTS

The analysis replicated the three Wave 1 profiles as the best theoretical fit: Vulnerables; Copers; and Resilients. Stability was most common, but some participants moved to more or less adaptive profiles, the former being more frequent. Younger age, longer time since widowhood, new life perspectives facilitated adaptation. Those transitioning to less adaptive profiles were more likely to be women and older.

DISCUSSION

The path to adaptation was not linear. Many of the explanatory variables contributed both to positive and negative adaptation. These include previous caring experience, education, psychological resilience and personal strength. This suggests these explanatory variables do not act in isolation but are likely to interact with each other, and with other, yet not measured, factors.

Stress, Resilience, and Well-Being in Italian Children and Their Parents during the COVID-19 Pandemic

The novel coronavirus (COVID-19) outbreak has forced parents and children to adopt significant changes in their daily routine, which has been a big challenge for families, with important implications for family stress. In this study, we aimed to analyze the potential risk and protective factors for parents' and children's well-being during a potentially traumatic event such as the COVID-19 quarantine. Specifically, we investigated parents' and children's well-being, parental stress, and children's resilience. The study involved 463 Italian parents of children aged 5-17. All participants completed an online survey consisting of the Psychological General Well Being Index (PGWB) to assess parental well-being, the Strengths and Difficulties Questionnaire (SDQ) to measure children's well-being, the Parent Stress Scale (PSS) to investigate parental stress, and the Child and Youth Resilience Measure (CYRM-R) to measure children's resilience. The results show that confinement measures and changes in daily routine negatively affect parents' psychological dimensions, thus exposing children to a significant risk for their well-being. Our results also detect some risk factors for psychological maladjustments, such as parental stress, lower levels of resilience in children, changes in working conditions, and parental psychological, physical, or genetic problems. In this study, we attempted to identify the personal and contextual variables involved in the psychological adjustment to the COVID-19 quarantine to identify families at risk for maladjustment and pave the way for ad hoc intervention programs intended to support them. Our data show promising results for the early detection of the determinants of families' psychological health. It is important to focus attention on the needs of families and children-including their mental health-to mitigate the health and economic implications of the COVID-19 pandemic.

What Does Resilience Signify? An Evaluation of Concepts and Directions for Future Research

Throughout the life course, individuals are confronted with adversities that challenge their ability to live the life they imagined. Adversities that are the most prominently studied and shown to bring about the most serious consequences for adjustment across the adult lifespan include job loss, disease and disability onset, and spousal and child bereavement. However, not all individuals show sustained declines to adversity; some are able to bounce back. The resilience literature is built on the premise that individuals are able to bounce back, or adapt to adversity. The past 15-20 years have seen an abundance of resilience research examining resilience to diverse types of adversity across the adult life-span. The overarching goal of this paper is to evaluate psychological concepts of resilience in adulthood and old age and recommend avenues for future research. To do so, I first evaluate and discuss definitions of resilience and their overlap across literatures with an emphasis on sociological approaches to studying adversity across the adult lifespan. Second, I discuss promising conceptual and methodological approaches to advance the resilience literature in adulthood and old age. Conceptual approaches to furthering the resilience literature include incorporating an anticipation component into the definition of resilience. Methodological approaches to furthering the resilience literature include prospective longitudinal designs that incorporate quantitative and qualitative approaches, multidimensional assessments, and the need to examine repeated adversities or multiple adversities that transpire in relatively close proximity to one another.

Mental health of older widows and widowers: Which coping strategies are most protective?

I examine: whether specific emotion-focused coping and help-seeking strategies adopted by older widow(er)s 6 months postloss affect depressive, anger, and yearning symptoms 1 year later; whether these effects are accounted for by psychosocial factors which guide the selection of coping strategies; and the extent to which patterns differ by gender. I estimate nested multivariate OLS regression models using data from the Changing Lives of Older Couples, a prospective multiwave survey of spousal bereavement (N = 164). Widows are more likely to use positive reframing, active distraction, help-seeking, and turning to God for strength, whereas widowers tend to use avoidant strategies, and are more likely to seek connection with their late spouse. Avoidant strategies like trying to forget and dulling the pain with alcohol increase depressive and anger symptoms; substance use is particularly consequential for men's anger symptoms. Positive reframing increases depressive symptoms yet mitigates against anger. Seeking comfort from God also protects against anger. Seeking help from a doctor increases anger and depressive symptoms in baseline models, although effects are accounted for by selection. Maladaptive coping strategies are linked with anger, whereas depression and yearning are relatively immune to coping strategies, reflecting the relatively short-lived time course of these two symptoms. The results carry implications for bereavement theories and mental health interventions targeting older widow(er)s. Older widowers who cope by turning to unhealthy behaviors are especially prone to anger, which has documented physical health effects and may alienate potential sources of social support.

The Development of the Widowhood Resilience Scale

Widowhood researchers have been increasingly interested in the construct of resilience and identifying factors which contribute to adaptive responses to conjugal loss. Available measures of general resilience were validated on nonwidowed samples and broadly lack face validity for use with widowed people. This article reports the development and validation of a resilience scale specific to widowhood, the Widowhood Resilience Scale. Initially, qualitative responses from 744 widowed people were analyzed and cross-referenced with existing literature on resilience to develop 49 items. The 49 items were tested on a sample of 1,188 widowed people, resulting in a 6-factor, 25-item scale.

Constrained Fourth Order Latent Differential Equation Reduces Parameter Estimation Bias for Damped Linear Oscillator Models

Second order linear differential equations can be used as models for regulation since under a range of parameter values they can account for return to equilibrium as well as potential oscillations in regulated variables. One method that can estimate parameters of these equations from intensive time series data is the method of Latent Differential Equations (LDE). However, the LDE method can exhibit bias in its parameters if the dimension of the time delay embedding and thus the width of the convolution kernel is not chosen wisely. This article presents a simulation study showing that a constrained fourth order Latent Differential Equation (FOLDE) model for the second order system almost completely eliminates bias as long as the width of the convolution kernel is less than two thirds the period of oscillations in the data. The FOLDE model adds two degrees of freedom over the standard LDE model but significantly improves model fit.

Performance and psychometric properties of the Interpersonal Support Evaluation List (ISEL) in older adults with Complicated Grief

BACKGROUND

Complicated Grief (CG) is a recently recognized bereavement-related mental health disorder. Social support is commonly measured with the Interpersonal Support Evaluation List (ISEL), a 40-item, 4-factor, self-report measure. Though the ISEL has been well-studied, no identified research has examined its psychometric properties or performance in older adults with CG.

METHODS

We examined the psychometric properties of the ISEL in adults age ≥60 who enrolled in a psychotherapy treatment study for CG in New York City. We also examined the association of ISEL scores with CG severity, and with clinical and sociodemographic variables.

RESULTS

Internal consistency of the ISEL was high (α=0.95). Confirmatory factor analysis indicated that most of the ISEL items loaded strongly (>0.45) on the original 4 factors. Mean ISEL score was 68.1, which indicated lower social support than population norms. ISEL scores were significantly but modestly negatively correlated with grief severity. ISEL total scores also varied by sociodemographic and clinical variables; never being married, depression or anxiety diagnosis, and living alone were all associated with lower ISEL scores.

LIMITATIONS

A clinical help-seeking sample, with low sociodemographic and geographic variability, may limit the generalizability of the findings. Also, analyses were cross-sectional and directionality of associations could not be determined.

CONCLUSIONS

The 40-item ISEL may be a useful measure for those studying social support in the context of CG. Given the strikingly low levels of social support, intervention strategies for CG should include components addressing social support.

As Good as GOLD: Gram-Schmidt Orthogonalization by Another Name

Generalized orthogonal linear derivative (GOLD) estimates were proposed to correct a problem of correlated estimation errors in generalized local linear approximation (GLLA). This paper shows that GOLD estimates are related to GLLA estimates by the Gram-Schmidt orthogonalization process. Analytical work suggests that GLLA estimates are derivatives of an approximating polynomial and GOLD estimates are linear combinations of these derivatives. A series of simulation studies then further investigates and tests the analytical properties derived. The first study shows that when approximating or smoothing noisy data, GLLA outperforms GOLD, but when interpolating noisy data GOLD outperforms GLLA. The second study shows that when data are not noisy, GLLA always outperforms GOLD in terms of derivative estimation. Thus, when data can be smoothed or are not noisy, GLLA is preferred whereas when they cannot then GOLD is preferred. The last studies show situations where GOLD can produce biased estimates. In spite of these possible shortcomings of GOLD to produce accurate and unbiased estimates, GOLD may still provide adequate or improved model estimation because of its orthogonal error structure. However, GOLD should not be used purely for derivative estimation because the error covariance structure is irrelevant in this case. Future research should attempt to find orthogonal polynomial derivative estimators that produce accurate and unbiased derivatives with an orthogonal error structure.

Is giving or receiving psychologically beneficial to older mothers in South Korea? Importance of marital status

In order to understand intergenerational financial transfers and subjective well-being for older mothers, this study argues that marital status is an important factor to be considered. Using the first wave of the Korean Longitudinal Study of Aging (KLoSA), this study finds that married older mothers report higher levels of life satisfaction when they provide economic support but widowed older mothers feel higher levels of life satisfaction when they receive economic support. Also, regular or irregular financial support appears to also matter in the associations between financial support and life satisfaction. These findings suggest that married and widowed older mothers have different viewpoints about the parent-children relationship.

The multidimensional nature of resilience to spousal loss

Spousal loss can be one of the most devastating events to occur across one's life, resulting in difficulties across different spheres of adjustment; yet, past research on resilience to bereavement has primarily focused on single adjustment indicators. We applied growth mixture modeling to data from 421 participants from the Household Income and Labour Dynamics of Australia Study who experienced spousal loss during the course of the study to examine (a) the extent to which individuals appear to be resilient across 3 indicators of subjective well-being-life satisfaction, negative affect, and positive affect, and 2 indicators of health-perceptions of general health and physical functioning-and (b) factors that might promote resilience. Approximately 66%, 19% and 26% individuals showed resilient trajectories, respectively, for life satisfaction, negative affect, and positive affect, whereas 37% and 28% showed resilience, respectively, for perceptions of general health and physical functioning. When we considered all 5 indicators simultaneously, only 8% showed "multidimensional" resilience, whereas 20% showed a non-resilient trajectory across all 5 indicators. The strongest predictors of resilient trajectories were continued engagement in everyday life activities and in social relationships, followed by anticipation that people would comfort them in times of distress. Overall, our findings demonstrate that resilience in the face of spousal bereavement is less common than previously thought. More importantly, they underscore the critical importance of multidimensional approaches while operationalizing doing well in the context of serious life adversities. (PsycINFO Database Record

Perceived Control Over Aging-Related Declines

The belief that people are in control of desired outcomes, including those associated with aging, is a hallmark of American culture. Nevertheless, older adults are less likely than the young to believe there are things that can be done to control aging-related declines in areas such as memory. Within age groups, individual differences in control beliefs are related to cognitive performance, health, and well-being. Mechanisms linking perceived control and positive outcomes include adaptive behaviors such as strategy use and physical activity. There is some evidence that control beliefs can be modified in later life, as illustrated in an intervention for fear of falling. Further work is needed to examine the antecedents of perceived control in later life and the implications of control beliefs in other aging-related domains.

Changes in life satisfaction when losing one's spouse: individual differences in anticipation, reaction, adaptation and longevity in the German Socio-economic Panel Study (SOEP)

Losing a spouse is among the most devastating events that may occur in people's lives. We use longitudinal data from 1,224 participants in the German Socio-economic Panel Study (SOEP) to examine (a) how life satisfaction changes with the experience of spousal loss; (b) whether socio-demographic factors and social and health resources moderate spousal loss-related changes in life satisfaction; and (c) whether extent of anticipation, reaction and adaptation to spousal loss are associated with mortality. Results reveal that life satisfaction shows anticipatory declines about two and a half years prior to (anticipation), steep declines in the months surrounding (reaction) and lower levels after spousal loss (adaptation). Older age was associated with steeper anticipatory declines, but less steep reactive declines. Additionally, younger age, better health, social participation and poorer partner health were associated with better adaptation. Higher pre-loss life satisfaction, less steep reactive declines and better adaptation were associated with longevity. The discussion focuses on the utility of examining the interrelatedness among anticipation, reaction and adaptation to further our understanding of change in life satisfaction in the context of major life events.

Dynamics of Change and Change in Dynamics

A framework is presented for building and testing models of dynamic regulation by categorizing sources of differences between theories of dynamics. A distinction is made between the dynamics of change, i.e., how a system self-regulates on a short time scale, and change in dynamics, i.e., how those dynamics may themselves change over a longer time scale. In order to clarify the categories, models are first built to estimate individual differences in equilibrium value and equilibrium change. Next, models are presented in which there are individual differences in parameters of dynamics such as frequency of fluctuations, damping of fluctuations, and amplitude of fluctuations. Finally, models for within-person change in dynamics over time are proposed. Simulations demonstrating feasibility of these models are presented and OpenMx scripts for fitting these models have been made available in a downloadable archive along with scripts to simulate data so that a researcher may test a selected models' feasibility within a chosen experimental design.

Behavior Genetics and the Within-Person Variability of Daily Interpersonal Styles: The Heritability of Flux, Spin and Pulse

A classical twin study was used to estimate the magnitude of genetic and environmental influences on four measurements of within-person variability: dominance flux, warmth flux, spin and pulse. Flux refers to the variability of an individual's interpersonal dominance and warmth. Spin measures changes in the tone of interpersonal styles and pulse measures changes in the intensity of interpersonal styles. Daily reports of interpersonal styles were collected from 494 same-sex female twins (142 monozygotic pairs and 105 dizygotic pairs) over 45 days. For dominance flux, warmth flux, and spin, genetic effects accounted for a larger proportion of variance (37%, 24%, and 30%, respectively) than shared environmental effects (14%, 13%, 0%, respectively), with the remaining variance due to the non-shared environment (62%, 50%, 70% respectively). Pulse appeared to be primarily influenced by the non-shared environment, although conclusions about the contribution of familial influences were difficult to draw from this study.

Dynamical systems analysis applied to working memory data

In the present paper we investigate weekly fluctuations in the working memory capacity (WMC) assessed over a period of 2 years. We use dynamical system analysis, specifically a second order linear differential equation, to model weekly variability in WMC in a sample of 112 9th graders. In our longitudinal data we use a B-spline imputation method to deal with missing data. The results show a significant negative frequency parameter in the data, indicating a cyclical pattern in weekly memory updating performance across time. We use a multilevel modeling approach to capture individual differences in model parameters and find that a higher initial performance level and a slower improvement at the MU task is associated with a slower frequency of oscillation. Additionally, we conduct a simulation study examining the analysis procedure's performance using different numbers of B-spline knots and values of time delay embedding dimensions. Results show that the number of knots in the B-spline imputation influence accuracy more than the number of embedding dimensions.

Trajectories of social support and well-being across the first two years of widowhood

The death of a spouse can be one of the most challenging events an older adult can face, yet many exhibit resilience. The present study examined the trajectories of structural and functional social support components, depression, and life satisfaction across the first two years of widowhood. The majority of structural and functional support trajectories exhibited stability across the first two years postloss. However, emotional support and support provided by family members did display a slight decline across time. Depression showed a linear pattern across time (e.g., decline in depressive symptomology) and life satisfaction demonstrated evidence of a one-year anniversary effect.

Do afterlife beliefs affect psychological adjustment to late-life spousal loss?

OBJECTIVES

We explore whether beliefs about the existence and nature of an afterlife affect 5 psychological symptoms (anxiety, anger, depression, intrusive thoughts, and yearning) among recently bereaved older spouses.

METHOD

We conduct multivariate regression analyses using data from the Changing Lives of Older Couples (CLOC), a prospective study of spousal loss. The CLOC obtained data from bereaved persons prior to loss and both 6 and 18 months postloss. All analyses are adjusted for health, sociodemographic characteristics, and preloss marital quality.

RESULTS

Bleak or uncertain views about the afterlife are associated with multiple aspects of distress postloss. Uncertainty about the existence of an afterlife is associated with elevated intrusive thoughts, a symptom similar to posttraumatic distress. Widowed persons who do not expect to be reunited with loved ones in the afterlife report significantly more depressive symptoms, anger, and intrusive thoughts at both 6 and 18 months postloss.

DISCUSSION

Beliefs in an afterlife may be maladaptive for coping with late-life spousal loss, particularly if one is uncertain about its existence or holds a pessimistic view of what the afterlife entails. Our findings are broadly consistent with recent work suggesting that "continuing bonds" with the decedent may not be adaptive for older bereaved spouses.

Synchrony in affect among stressed adults: the Notre Dame Widowhood Study

OBJECTIVES

This study examined 3 types of synchrony (i.e., asynchrony, synchrony, and desynchrony) between positive and negative affect in a sample of adult widows and assessed whether individual differences in synchrony type predicted adjustment over time.

METHODS

Participants included 34 widows from the Notre Dame Widowhood Study, who reported on their positive and negative affect across a 98-day period following conjugal loss and responded to follow-up questionnaires every 4 months for 1 year.

RESULTS

Multilevel models revealed that although the nomothetic average of the synchrony scores indicated a negative or desynchronous relationship between positive and negative affect, an ideographic view identified evidence of individual differences. Furthermore, patterns of change in the relationship between positive and negative affect suggested that, over time, desynchrony in affect generally abates for widows but individual differences were predictive of adjustment over time. Furthermore, distinct trajectories that the women follow from the time of their husband's death include patterns of resilience and delayed negative reaction, each of which predicted present levels of grief.

DISCUSSION

Discussion focuses on (a) individual differences in the within-person structure in affect, (b) the dynamic processes involving negative and positive affect, and (c) the predictive power of synchrony scores.

The reservoir model: a differential equation model of psychological regulation

Differential equation models can be used to describe the relationships between the current state of a system of constructs (e.g., stress) and how those constructs are changing (e.g., based on variable-like experiences). The following article describes a differential equation model based on the concept of a reservoir. With a physical reservoir, such as one for water, the level of the liquid in the reservoir at any time depends on the contributions to the reservoir (inputs) and the amount of liquid removed from the reservoir (outputs). This reservoir model might be useful for constructs such as stress, where events might "add up" over time (e.g., life stressors, inputs), but individuals simultaneously take action to "blow off steam" (e.g., engage coping resources, outputs). The reservoir model can provide descriptive statistics of the inputs that contribute to the "height" (level) of a construct and a parameter that describes a person's ability to dissipate the construct. After discussing the model, we describe a method of fitting the model as a structural equation model using latent differential equation modeling and latent distribution modeling. A simulation study is presented to examine recovery of the input distribution and output parameter. The model is then applied to the daily self-reports of negative affect and stress from a sample of older adults from the Notre Dame Longitudinal Study on Aging.

Intraindividual Variability and Stability of Affect and Well-Being

Whereas subjective well-being remains relatively stable across adulthood, emotional experiences show remarkable short-term variability, with younger and older adults differing in both amount and correlates. Repeatedly assessed affect data captures both the dynamics and stability as well as stabilization that may indicate emotion-regulatory processes. The article reviews (1) research approaches to intraindividual affect variability, (2) functional implications of affect variability, and (3) age differences in affect variability. Based on this review, we discuss how the broader literature on emotional aging can be better integrated with theories and concepts of intraindividual affect variability by using appropriate methodological approaches. Finally, we show how a better understanding of affect variability and its underlying processes could contribute to the long-term stabilization of well-being in old age.

Selection, Optimization, Compensation, and Equilibrium Dynamics

One of the major theoretic frameworks through which human development is studied is a process-oriented model involving selection, optimization, and compensation. These three processes each provide accounts for methods by which gains are maximized and losses minimized throughout the lifespan, in particular during later life. These processes can be cast within the framework of dynamical systems theory and then modeled using differential equations. The current article will review basic tenets of selection, optimization, and compensation while introducing language and concepts from dynamical systems. Four categories of interindividual differences and intraindividual variability in dynamics are then described and discussed in the context of selection, optimization, and compensation.

Maintaining a Sense of Control in the Context of Cognitive Challenge: Greater Stability in Control Beliefs Benefits Working Memory

We considered the functional role of control beliefs for cognitive performance by focusing on patterns of stability across multiple trials increasing in level of difficulty. We assessed 56 adults aged 18-88 on working memory tasks. We examined stability vs. lability (intraindividual variability, IIV) in control beliefs and the relationships with anxiety, distraction, and performance. Age was positively associated with IIV in control and performance, and IIV increased with task difficulty. Those maintaining stable control beliefs had better performance, and showed less anxiety and distraction. Those with lower stability and less control showed steeper declines in performance and increases in distraction. The findings suggest that stability of control beliefs may serve a protective function in the context of cognitively challenging tasks.

A longitudinal analysis of social engagement in late-life widowhood

Very little is known of the longitudinal changes that occur in contact with children and participation in social activities during late-life widowhood. Using data on social networks and activities drawn from the Australian Longitudinal Study of Ageing, trajectories of change in social engagement were modeled for 1266 participants (mean age 76.7 years) over a 16-year period. Levels of social engagement were found to remain high during older age and rose following the transition to widowhood. Frequency of phone contact with children and participation in social activities were higher for widowed than married participants. However, the very-old, males, those in lower socio-economic groups, in poorer health, or without a child living nearby were found to have lower levels of social engagement in widowhood, and may be at increased risk of social isolation. High levels of social engagement during widowhood may assist individuals in successfully overcoming the challenges of spousal bereavement.

Posttraumatic stress disorder following the September 11, 2001, terrorist attacks: a review of the literature among highly exposed populations

The September 11, 2001 (9/11), terrorist attacks were unprecedented in their magnitude and aftermath. In the wake of the attacks, researchers reported a wide range of mental and physical health outcomes, with posttraumatic stress disorder (PTSD) the one most commonly studied. In this review, we aim to assess the evidence about PTSD among highly exposed populations in the first 10 years after the 9/11 attacks. We performed a systematic review. Eligible studies included original reports based on the full Diagnostic and Statistical Manual of Mental Disorders (4th ed., rev.; American Psychiatric Association, 2000) criteria of PTSD among highly exposed populations such as those living or working within close proximity to the World Trade Center (WTC) and the Pentagon in New York City and Washington, DC, respectively, and first responders, including rescue, cleaning, and recovery workers. The large body of research conducted after the 9/11 attacks in the past decade suggests that the burden of PTSD among persons with high exposure to 9/11 was substantial. PTSD that was 9/11-related was associated with a wide range of correlates, including sociodemographic and background factors, event exposure characteristics, loss of life of significant others, and social support factors. Few studies used longitudinal study design or clinical assessments, and no studies reported findings beyond six years post-9/11, thus hindering documentation of the long-term course of confirmed PTSD. Future directions for research are discussed.

Latent Differential Equation Modeling of Self-Regulatory and Coregulatory Affective Processes

We examine emotion self-regulation and coregulation in romantic couples using daily self-reports of positive and negative affect. We fit these data using a damped linear oscillator model specified as a latent differential equation to investigate affect dynamics at the individual level and coupled influences for the 2 partners in each couple. Results indicate an absence of damping of relationship-specific affect within individuals in the sample. When both positive and negative affect are modeled at the individual level, the influence of positive affect is greater than that of negative affect. At the dyad level, the findings indicate coupled influences in both positive and negative affect between partners. With regard to positive affect, females are sensitive to their partners' overall displacement from average as well as their rate of change; males are sensitive only to their partners' displacement from average. For negative affect both partners are sensitive to each other's displacement from average, yet there are no coupled influences for rates of change in this dimension. We interpret the influence of the parameters on the system by examining the expected behavior of the system as a function of varying parameter values.

Integrating the dynamics of personality and close relationship processes: methodological and data analytic implications

A common theme that has emerged from classic and contemporary theoretical work in both the fields of personality and relationship science is a focus on process. Current process-focused theories bearing on personality invoke a view of the individual in ongoing action and interaction with the environment, reflecting a flow of experience rather than a static depiction. To understand the processes by which personality interacts with the social environment (particularly dyads), investigations must capture individuals interacting in multiple interpersonal situations, which likely necessitates complex study designs and corresponding data analytic strategies. Using an illustrative simulated data set, we focus on diary methods and corresponding individual and dyadic multilevel models to capture person-situation interaction within the context of processes in daily close relationship life. Finally, we consider future directions that conceptualize personality and close relationship processes from a dynamical systems theoretical and methodological perspective.

Complicated grief associated with hurricane Katrina

BACKGROUND

Although losses are important consequences of disasters, few epidemiological studies of disasters have assessed complicated grief (CG) and none assessed CG associated with losses other than death of loved one.

METHODS

Data come from the baseline survey of the Hurricane Katrina Community Advisory Group, a representative sample of 3,088 residents of the areas directly affected by Hurricane Katrina. A brief screen for CG was included containing four items consistent with the proposed DSM-V criteria for a diagnosis of bereavement-related adjustment disorder.

RESULTS

Fifty-eight and half percent of respondents reported a significant hurricane-related loss: Most-severe losses were 29.0% tangible, 9.5% interpersonal, 8.1% intangible, 4.2% work/financial, and 3.7% death of loved one. Twenty-six point one percent respondents with significant loss had possible CG and 7.0% moderate-to-severe CG. Death of loved one was associated with the highest conditional probability of moderate-to-severe CG (18.5%, compared to 1.1-10.5% conditional probabilities for other losses), but accounted for only 16.5% of moderate-to-severe CG due to its comparatively low prevalence. Most moderate-to-severe CG was due to tangible (52.9%) or interpersonal (24.0%) losses. Significant predictors of CG were mostly unique to either bereavement (racial-ethnic minority status, social support) or other losses (prehurricane history of psychopathology, social competence.).

CONCLUSIONS

Nonbereavement losses accounted for the vast majority of hurricane-related possible CG despite risk of CG being much higher in response to bereavement than to other losses. This result argues for expansion of research on CG beyond bereavement and alerts clinicians to the need to address postdisaster grief associated with a wide range of losses.

Do personality traits moderate the effect of late-life spousal loss on psychological distress?

We use data from the Changing Lives of Older Couples (CLOC) study to investigate the extent to which: (1) five personality traits (agreeableness, conscientiousness, emotional stability/neuroticism, extraversion, and openness) moderate the effect of late-life spousal loss on depressive symptoms; (2) these patterns vary based on the expectedness of the death; and (3) the patterns documented in (1) and (2) are explained by secondary stressors and social support. Widowed persons report significantly more depressive symptoms than married persons, yet the deleterious effects of loss are significantly smaller for highly extraverted and conscientious individuals. The protective effects of personality traits, however, vary based on the expectedness of the death. Extraversion is protective against depression only for persons who had forewarning of the death. Extraverts may be particularly good at marshalling social support during prolonged periods of spousal illness. We discuss the ways that extraversion and conscientiousness may buffer against bereavement-related stressors.

"Well if he could see me now": the facilitators and barriers to the promotion of instrumental independence following spousal bereavement

Older widows face challenges regarding domestic instrumental tasks and independence. We asked 21 British widows about traditional male tasks, pre- and postbereavement. We focus on 3 aspects. First, what changes occurred in instrumental independence following bereavement? A typology of 4 was identified comprising: dependent/independent; dependent/dependent; independent/independent; independent/dependent. Second, what was the nature of independence? Third, what factors promoted or hindered independence? These included familial factors, both as aids and barriers, financial security as an aid, and health as a barrier. The results highlight how successfully widows manage instrumental tasks and how their independence could be enhanced.

Time Delay Embedding Increases Estimation Precision of Models of Intraindividual Variability

This paper investigates the precision of parameters estimated from local samples of time dependent functions. We find that time delay embedding, i.e. structuring data prior to analysis by constructing a data matrix of overlapping samples, increases the precision of parameter estimates and in turn statistical power compared to standard independent rows of panel data. We show that the reason for this effect is that the sign of estimation bias depends on the position of a misplaced data point if there is no a priori knowledge about initial conditions of the time dependent function. Hence, we reason that the advantage of time delayed embedding is likely to hold true for a wide variety of functions. We support these conclusions both by mathematical analysis and two simulations.

Resilience comes of age: defining features in later adulthood

Historically, resilience research has been largely the purview of developmental investigators dealing with early childhood and adolescence. This research primarily focused on at-risk children who were exposed to significant and severe life adversities (e.g., extreme poverty, parental mental illness, community violence). The study of resilience in adulthood and later life, by comparison, remains largely understudied. In this article, we describe a program of research on adulthood resilience. We begin with a selective review of the broad literature on resilience, giving emphasis to the major approaches, empirical findings, and guiding principles that characterize prior studies. We then summarize our own approach to the phenomenon of resilience and illustrate select parts of our previous and ongoing studies of older adults. Findings from this research add to the growing body of empirical evidence suggesting that resilience is a common phenomenon that emerges from the coordinated orchestration of basic human adaptive processes.

Modeling Individual Damped Linear Oscillator Processes with Differential Equations: Using Surrogate Data Analysis to Estimate the Smoothing Parameter

Among the many methods available for modeling intraindividual time series, differential equation modeling has several advantages that make it promising for applications to psychological data. One interesting differential equation model is that of the damped linear oscillator (DLO), which can be used to model variables that have a tendency to fluctuate around some typical, or equilibrium, value. Methods available for fitting the damped linear oscillator model using differential equation modeling can yield biased parameter estimates when applied to univariate time series. The degree of this bias depends on a smoothing-like parameter, which balances the need for increasing smoothing to minimize error variance but not smoothing so much as to obscure change of interest. This article explores a technique that uses surrogate data analysis to select such a parameter, thereby producing approximately unbiased parameter estimates. Furthermore the smoothing parameter, which is usually researcher-selected, is produced in an automated manner so as to reduce the experience required by researchers to apply these methods. Focus is placed on the damped linear model; however, similar issues are expected with other differential equation models and other techniques in which parameter estimates depend on a smoothing parameter. An example using affect data from the Notre Dame Longitudinal Study of Aging (2004) is presented, which contrasts the use of a single smoothing parameter for all individuals versus use of a smoothing parameter for each individual.

The human capacity to thrive in the face of potential trauma

For decades, researchers have documented remarkable levels of resilience in children who were exposed to corrosive early environments, such as those in which poverty or chronic maltreatment were present; however, relatively little research has examined resilience in children or adults who were exposed to isolated and potentially traumatic events. The historical emphasis on psychological and physiologic dysfunction after potentially traumatic events has suggested that such events almost always produce lasting emotional damage. Recent research, however, has consistently shown that across different types of potentially traumatic events, including bereavement, serious illness, and terrorist attack, upward of 50% of people have been found to display resilience. Research has further identified substantial individual variation in response to potentially traumatic events, including 4 prototypical and empirically derived outcome trajectories: chronic dysfunction, recovery, resilience, and delayed reactions. Factors that promote resilience are heterogeneous and include a variety of person-centered variables (eg, temperament of the child, personality, coping strategies), demographic variables (eg, male gender, older age, greater education), and sociocontextual factors (eg, supportive relations, community resources). It is surprising that some factors that promote resilience to potentially traumatic events may be maladaptive in other contexts, whereas other factors are more broadly adaptive. Given the growing evidence that resilience is common, psychotherapeutic treatment should be reserved for those in genuine need.

Social Support in Widowhood: A Mixed Methods Study

Although social support is assumed to be an important factor following loss, the mechanisms by which it influences outcomes are not well understood. This study explored the nature of social support following loss using mixed methods. Widows participated in semistructured interviews 1 and 4 months after loss; a subsample completed 98 days of questionnaires between interviews. Interviews were analyzed using the constant comparative method; themes included the importance of supportive groups and the meaning of support. Social support trajectories were examined using hierarchical linear modeling; perceived social control explained differences in trajectories. Additional interviews were selected by their maximally divergent plots. The findings of these analyses were integrated to contribute a more detailed description of social support in the transition to widowhood.
