Age differences in emotion regulation strategy use and flexibility in daily life.

OBJECTIVES: Age-related shifts in emotion regulation patterns are important for explaining preserved emotional well-being in late adulthood amidst declines in physical and cognitive health. Although several studies have examined age-related shifts in emotion regulation strategy use, age differences in how specific strategies are flexibly adapted to shifting contexts in daily life and the adaptiveness of such shifts remains poorly understood. METHODS: 130 younger adults (ages 22-35) and 130 older adults (ages 65-85) completed a modified Day Reconstruction Method Assessment and self-report questionnaires to examine age differences in emotion regulation strategy use and one aspect of emotion regulation flexibility (responsiveness) in daily life, and the adaptive implications of these differences. RESULTS: Older adults exhibited more frequent acceptance use, less frequent distraction use, and less flexibility in the responsiveness of strategies with varying negative affect. Across age groups, the use of expressive suppression and distraction was associated with less adaptive outcomes, whereas higher acceptance responsiveness, positive reappraisal responsiveness, and situation selection responsiveness were associated with more adaptive outcomes. Age-group moderated the associations between adaptiveness metrics with the use and flexibility of several emotion regulation strategies. CONCLUSION: The current findings provide early evidence of age-related decreases in emotion regulation flexibility as well as age-related shifts in the adaptiveness of emotion regulation patterns.

Accelerometry measures of physical activity and sedentary behavior: Associations with cognitive functioning in MS.

BACKGROUND: Cognitive dysfunction is a pervasive symptom of multiple sclerosis (MS). Correlational evidence on the relationships between physical activity, sedentary behavior, and cognition has been mixed and limited to a few activity measures. The collinearity of accelerometry-based metrics has precluded an assessment of the full activity spectrum. Here, we aimed to examine the rich set of activity measures using analytic approaches suitable for collinear metrics. We investigated the combination of physical activity, sedentary, and clinicodemographic measures that explain the most variance in composite scores of working memory/processing speed, visual memory, and verbal memory. METHODS: We analyzed baseline accelerometry and neuropsychological data (n = 80) from a randomized controlled trial of pedometer tracking. Using partial least squares regression (PLSR), we built three models to predict latent scores on the three domains of cognition using 12 activity metrics, sex, education, and Expanded Disability Status Scale (EDSS) scores. Significance was assessed using linear regression models with model component scores as predictors and cognitive composites as outcomes. RESULTS: The latent component was significant for working memory/processing speed but was not significant for visual memory and verbal memory after Bonferroni correction. Working memory/processing speed was positively associated with average kilocalories, moderate-to-vigorous physical activity (MVPA), steps, and sex (i.e., higher scores in males) and negatively related to duration of long sedentary bouts and EDSS. CONCLUSIONS: These findings suggest that increasing overall energy expenditure through walking and MVPA, while decreasing prolonged sedentary time may positively benefit working memory/processing speed in people with MS.

Protocol for a randomized controlled trial of mindfulness-based stress reduction to improve attentional control in older adults (HealthyAgers trial).

BACKGROUND: Mindfulness meditation is a form of mind-body intervention that has increasing scientific support for its ability to reduce age-related declines in cognitive functioning, improve affective health, and strengthen the neural circuitry supporting improved cognitive and affective health. However, the majority of existent studies have been pilot investigations with small sample sizes, limited follow-up data, and a lack of attention to expectancy effects. Here, we present the study design of a Phase I/II, efficacy trial-HealthyAgers trial-that examines the benefits of a manualized mindfulness-based stress reduction program in improving attentional control and reducing mind-wandering in older adults. METHODS: One hundred fifty older adults (ages 65-85 years) will be randomized into one of two groups: an eight-week mindfulness program or an eight-week, placebo-controlled, lifestyle education program. Behavioral and neuroimaging assessments are conducted before and after the training. Participants are then invited to booster sessions once every three months for a period of 12 months with post-intervention follow-up assessments conducted at 6-months and 12-months. The primary outcomes for the study are behavioral measures of attentional control and mind-wandering. Additional, secondary outcomes include network strength in an a priori defined neuromarker of attentional control, fluid and everyday cognition, emotion regulation strategy use, and markers of inflammation. DISCUSSION: This study will establish the efficacy of a group-based, low-cost mind-body intervention for the inter-related facets of attentional control and mind-wandering in older adults. Strengths of this study include a well-designed, placebo-controlled comparison group, use of web/mobile application to track study adherence, and longitudinal follow-up.

Impact of mindfulness training on emotion regulation in multiple sclerosis: Secondary analysis of a pilot randomized controlled trial.

Purpose/Objective Research: This secondary analysis of a pilot randomized controlled trial in people with multiple sclerosis (PwMS) aimed to compare mindfulness-based training (MBT), adaptive cognitive training (aCT), and a waitlist control (WL) on the use of emotion regulation strategies during daily worries and ruminations. Further, we examined cognitive functioning as a moderator of training effects. RESEARCH METHOD/DESIGN: Sixty-one PwMS were randomized into an MBT, aCT, or a WL control group for four weeks. Participants completed daily diaries assessing their use of emotion regulation strategies and measures of cognitive functioning at pre- and posttraining. The frequency of acceptance use, maladaptive strategies, and cognitive reappraisal, as well as the success of acceptance use, were the primary outcomes of interest. We also examined whether a cognitive composite score moderated treatment gains. RESULTS: Relative to pretraining, at posttraining, participants in the MBT group used acceptance more frequently, and this change was significantly greater compared to the change in aCT and WL groups. Training did not have differential effects on the frequency of maladaptive strategy and cognitive reappraisal use or on the success of acceptance use. Cognitive functioning did not moderate observed treatment gains. CONCLUSION/IMPLICATIONS: Our findings, based on this pilot study, suggest that after brief training in mindfulness meditation, PwMS used more acceptance strategies to regulate their emotions. Future studies with larger sample sizes, longer duration of treatment, and longitudinal follow-up are needed to better understand the efficacy of mindfulness mediation for promoting affective and cognitive health in PwMS.

A promising cognitive screener in multiple sclerosis: The NIH toolbox cognition battery concords with gold standard neuropsychological measures.

BACKGROUND: Routine cognitive screening is a priority in MS clinical care. The National Institutes of Health Toolbox (NIHTB) Cognition Battery is a 30-min instrument validated in neurological populations excluding MS. OBJECTIVES: To assess construct validity of NIHTB tests and compare classification of cognitive impairment with gold-standard tests. To evaluate relationships between fluid cognition and clinical measures. METHODS: Eighty-seven individuals, aged 30-59 years, completed the NIHTB, Minimal Assessment of Cognitive Function in MS (MACFIMS), Wechsler Adult Intelligence Scale-IV subtests, and measures of disease severity, depression, and fatigue. RESULTS: The NIHTB showed adequate convergent validity for processing speed, working memory, and episodic memory. Although fluid cognition scores from the NIHTB and MACFIMS classified a similar proportion of participants as cognitively impaired, the two batteries differed in which individuals were classified as impaired versus preserved. NIHTB fluid cognition was inversely correlated with disease severity but not related to depression or fatigue. CONCLUSIONS: The NIHTB concords with gold-standard measures, and classifies cognitive impairment at similar rates to the MACFIMS. Adjusted NIHTB fluid cognition was negatively associated with disease severity suggesting clinical utility. Psychometric validation of the NIHTB in clinical practice will elucidate its promise as a cognitive screener in MS.

Trait mindfulness, emotion dysregulation, and depression in individuals with multiple sclerosis.

OBJECTIVES: Emotion dysregulation plays a role in the development and maintenance of psychopathology. Given the higher rates of mood disturbances in people with multiple sclerosis (PwMS), there is a need to explore the relationships between metrics of emotion dysregulation and potential protective traits. Mindfulness, a multi-faceted trait characteristic reflecting present moment awareness, is one such trait showing promise for positive associations with affective health. The current project assessed the relationship between trait mindfulness, the use of emotion regulation strategies during an emotionally evocative task, and depression in PwMS. METHODS: Sixty-one PwMS completed a worry/rumination induction task that examined emotion regulation strategy use in response to emotionally evocative stimuli. RESULTS: Higher trait mindfulness was associated with both lower symptoms of depression and greater employment of acceptance-based strategies following worry and rumination inductions. Acceptance use mediated the relationship between trait mindfulness and symptoms of depression. CONCLUSIONS: Our results suggest that the association between trait mindfulness and emotion dysregulation extends to the use of emotion regulation strategies during an emotionally evocative task. Additionally, emotion regulation strategy use, and acceptance in particular, may play a role in the relationship between trait mindfulness and depression. These findings suggest that increasing levels of mindfulness through clinical interventions may present a path toward improving emotion regulation, and by extension, reducing the symptoms of depression in PwMS.

Predicting response time variability from task and resting-state functional connectivity in the aging brain.

Aging is associated with declines in a host of cognitive functions, including attentional control, inhibitory control, episodic memory, processing speed, and executive functioning. Theoretical models attribute the age-related decline in cognitive functioning to deficits in goal maintenance and attentional inhibition. Despite these well-documented declines in executive control resources, older adults endorse fewer episodes of mind-wandering when assessed using task-embedded thought probes. Furthermore, previous work on the neural basis of mind-wandering has mostly focused on young adults with studies predominantly focusing on the activity and connectivity of a select few canonical networks. However, whole-brain functional networks associated with mind-wandering in aging have not yet been characterized. In this study, using response time variability-the trial-to-trial fluctuations in behavioral responses-as an indirect marker of mind-wandering or an "out-of-the-zone" attentional state representing suboptimal behavioral performance, we show that brain-based predictive models of response time variability can be derived from whole-brain task functional connectivity. In contrast, models derived from resting-state functional connectivity alone did not predict individual response time variability. Finally, we show that despite successful within-sample prediction of response time variability, our models did not generalize to predict response time variability in independent cohorts of older adults with resting-state connectivity. Overall, our findings provide evidence for the utility of task-based functional connectivity in predicting individual response time variability in aging. Future research is needed to derive more robust and generalizable models.

Impact of mindfulness training on in-the-moment attentional control and emotion dysregulation in older adults: secondary analysis of a pilot, placebo-controlled randomized controlled trial.

Mindfulness-based interventions show increasing promise for improving attention and emotion regulation- processes that critically support healthy aging. Given their complex, multi-faceted nature, identifying specific aspects of attention and emotion regulation that are modifiable with training in older adults, particularly compared with active control groups, is an ongoing challenge. We performed pre-registered, secondary analyses of a pilot randomized controlled trial comparing the effects of a four-week mindfulness-based attention training (MBAT) group and a lifestyle education (LifeEd) active control group on attention and emotion dysregulation in older adults. Differential training outcomes were assessed for: (a) in-the-moment effects of mind-wandering on sustained attention, measured by performance decrements preceding self-reported mind-wandering, and (b) self-reported emotion dysregulation. Baseline working memory (WM) performance was tested as a moderator of training effects. There were no significant between-group differences for change in in-the-moment effects of mind-wandering on attention or emotion dysregulation. However, baseline WM moderated training effects, such that older adults with higher WM showed greater reductions in emotion dysregulation following mindfulness training. This has potential implications for identifying aging cohorts that may benefit most from this type of training.

Employing Connectome-Based Models to Predict Working Memory in Multiple Sclerosis.

Introduction: Individuals with multiple sclerosis (MS) are vulnerable to deficits in working memory (WM), but the search for neural correlates of WM within circumscribed areas has been inconclusive. Given the widespread neural alterations observed in MS, predictive modeling approaches that capitalize on whole-brain connectivity may better capture individual differences in WM. Materials and Methods: We applied connectome-based predictive modeling to functional magnetic resonance imaging data from WM tasks in two independent samples with relapsing-remitting MS. In the internal sample (ninternal = 36), cross-validation was used to train a model to predict accuracy on the Paced Visual Serial Addition Test from functional connectivity. We hypothesized that this MS-specific model would successfully predict performance on the N-back task in the validation cohort (nvalidation = 36). In addition, we assessed the generalizability of existing WM networks derived in healthy young adults to these samples, and we explored anatomical differences between the healthy and MS networks. Results: We successfully derived an MS-specific predictive model of WM in the internal sample (full: rs = 0.47, permuted p = 0.011), but the predictions were not significant in the validation cohort (rs = -0.047; p = 0.78, mean squared error [MSE] = 0.006, R2 = -2.21%). In contrast, the healthy networks successfully predicted WM in both MS samples (internal: rs = 0.33 p = 0.049, MSE = 0.009, R2 = 13.4%; validation cohort: rs = 0.46, p = 0.005, MSE = 0.005, R2 = 16.9%), demonstrating their translational potential. Discussion: Functional networks identified in a large sample of healthy individuals predicted significant variance in WM in MS. Networks derived in small samples of people with MS may have limited generalizability, potentially due to disease-related heterogeneity. The robustness of models derived in large clinical samples warrants further investigation. ClinicalTrials.gov ID: NCT03244696.

Mindfulness Meditation: Impact on Attentional Control and Emotion Dysregulation.

OBJECTIVE: Theoretical models of mindfulness meditation conceptualize the cultivation of focused attention and regulation of emotional states, with the attitudinal foundations that promote nonjudgment and acceptance, to facilitate cognitive and affective processing resulting in improved brain health. Within the scientific study of mindfulness meditation, outcomes assessing behavioral and neural correlates of attentional control and emotion regulation have been examined for their malleability as a function of engagement in mindfulness practices. This review synthesizes the results of our pilot trials examining the preliminary effects of mindfulness meditation on metrics of cognitive, affective, and brain health in older adults and in individuals with multiple sclerosis. CONCLUSIONS: There is promising support for mindfulness meditation to enhance attentional control, reduce mind-wandering, and reduce emotion dysregulation. However, well-powered efficacy trials, with an objective assessment of mindfulness practice data are needed to further provide causal and comprehensive evidence supporting the efficacy of mindfulness meditation for brain health. Inclusion of independently derived and validated brain-based signatures of cognitive and affective functioning can additionally enable a parsimonious understanding of how mindfulness meditation can causally impact metrics of functional and structural integrity of the human brain.

Effects of 4-week mindfulness training versus adaptive cognitive training on processing speed and working memory in multiple sclerosis.

OBJECTIVE: The aim of this preregistered, secondary analysis of a pilot randomized controlled trial (NCT02717429) was to compare the impact of 4-week mindfulness-based training and adaptive cognitive training, with a waitlist control condition, on processing speed and working memory in people with multiple sclerosis (PwMS). METHOD: Sixty-one PwMS were randomized to mindfulness-based training (MBT), adaptive computerized cognitive training (aCT), or a waitlist (WL) control group and completed the Brief Repeatable Battery of Neuropsychological Tests at pre- and posttraining. Training-related changes on the Symbol Digit Modalities Test (SDMT) and the Paced Auditory Serial Addition Test (PASAT) were the primary outcomes of interest. Baseline cognitive status was examined as a moderator of treatment gains. Practice time, change in aCT game difficulty, and rate of change in state awareness across MBT were assessed as correlates of cognitive gains. FINDINGS: Compared with aCT and WL, mindfulness training significantly improved processing speed (ηp² = .14). Baseline cognitive status did not moderate change in processing speed (ηp² = .005) or working memory (ηp² = .014). Practice time and change in game difficulty were not significantly correlated with cognitive gains (all ps > .49). In the MBT group, rate of change in awareness was significantly associated with improvement in working memory (ρ = .52, p = .04). CONCLUSIONS: In PwMS, 4 weeks of mindfulness meditation training improved processing speed above and beyond aCT and WL. More rapid change in awareness during mindfulness training may be associated with greater gains in working memory. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Mindfulness training for emotion dysregulation in multiple sclerosis: A pilot randomized controlled trial.

OBJECTIVE: People with multiple sclerosis (PwMS) report greater emotion dysregulation, which is associated with increased symptoms of depression and anxiety, and reduced quality of life. Given the transdiagnostic significance of emotion dysregulation, the current study was designed to assess the feasibility and treatment effects of mindfulness meditation in reducing emotion dysregulation for PwMS. METHOD: Sixty-one PwMS were randomized to 1 of 3 groups: 4-week mindfulness-based training (MBT), 4-week adaptive cognitive training (aCT), or a waitlist control group. Using self-report and behavioral measures, we examined the effects of MBT on emotion dysregulation, use of emotion regulation strategies, experience of negative and positive affect, and overall quality of life. RESULTS: Mindfulness training was associated with reduced emotion dysregulation compared with the adaptive cognitive training and the waitlist control group (ηp² = .20). Relative to the waitlist group, the MBT group also demonstrated reductions on a composite score of preservative cognition, measuring rumination and worry (ηp² = .15). However, there was no differential use of emotion regulation strategies or between-groups differences in overall quality of life as a function of training. CONCLUSIONS: Our pilot study provides preliminary support for MBT to reduce self-reported emotion dysregulation in PwMS. Given the widespread prevalence of mental health disturbances in this population, MBT can serve as a promising rehabilitation tool for PwMS (clinicaltrials.gov # NCT02717429).

Mindfulness and Attention: Current State-of-Affairs and Future Considerations.

This review examines longitudinal studies of changes in components of attention following mindfulness training. A total of 57 retreat studies, non-randomized trials, and randomized controlled trials were identified. Employing the classical taxonomy proposed by Posner and Petersen (1990), outcome measures were broadly categorized based on whether they involved maintenance of an aroused state (alerting), selective prioritization of attention to target items (orienting), or assessed conflict monitoring (executive attention). Although many non-randomized and retreat studies provide promising evidence of gains in both alerting and conflict monitoring following mindfulness training, evidence from randomized controlled trials, especially those involving active control comparison groups, is more mixed. This review calls attention to the urgent need in our field of contemplative sciences to adopt the methodological rigor necessary for establishing mindfulness meditation as an effective cognitive rehabilitation tool. Although studies including wait-listed control comparisons were fruitful in providing initial feasibility data and pre-post effect sizes, there is a pressing need to employ standards that have been heavily advocated for in the broader cognitive and physical training literatures. Critically, inclusion of active comparison groups and explicit attention to the reduction of demand characteristics are needed to disentangle the effects of placebo from treatment. Further, detailed protocols for mindfulness and control groups and examination of theoretically guided outcome variables with established metrics for reliability and validity are key ingredients in the systematic study of mindfulness meditation. Adoption of such methodological rigor will allow for causal claims supporting mindfulness training as an efficacious treatment modality for cognitive rehabilitation and enhancement.

Connectome-based models predict attentional control in aging adults.

There are well-characterized age-related differences in behavioral and neural responses to tasks of attentional control. However, there is also increasing recognition of individual variability in the process of neurocognitive aging. Using connectome-based predictive modeling, a method for predicting individual-level behaviors from whole-brain functional connectivity, a sustained attention connectome-based prediction model (saCPM) has been derived in young adults. The saCPM consists of two large-scale functional networks: a high-attention network whose strength predicts better attention and a low-attention network whose strength predicts worse attention. Here we examined the generalizability of the saCPM for predicting inhibitory control in an aging sample. Forty-two healthy young adults (n = 21, ages 18-30) and older adults (n = 21, ages 60-80) performed a modified Stroop task, on which older adults exhibited poorer performance, indexed by higher reaction time cost between incongruent and congruent trials. The saCPM generalized to predict reaction time cost across age groups, but did not account for age-related differences in performance. Exploratory analyses were conducted to characterize the effects of age on functional connectivity and behavior. We identified subnetworks of the saCPM that exhibited age-related differences in strength. The strength of two low-attention subnetworks, consisting of frontoparietal, medial frontal, default mode, and motor nodes that were more strongly connected in older adults, mediated the effect of age group on performance. These results support the saCPM's ability to capture attention-related patterns reflected in each individual's functional connectivity signature across both task context and age. However, older and younger adults exhibit functional connectivity differences within components of the saCPM networks, and it is these connections that better account for age-related deficits in attentional control.

Aging and Attentional Control: Examining the Roles of Mind-Wandering Propensity and Dispositional Mindfulness.

OBJECTIVES: Aging is associated with declines in performance on certain laboratory tasks of attentional control. However, older adults tend to report greater mindful, present-moment attention and less mind-wandering (MW) than young adults. For older adults, high levels of these traits may be protective for attentional performance. This study examined age-related differences in global (i.e., full-task) and local (i.e., pre-MW) attentional control and explored the variance explained by MW and mindfulness. METHODS: Cross-sectional comparisons were conducted on data from a previously reported sample of 75 older adults (ages, 60-75 years) and a new sample of 50 young adults (ages, 18-30 years). All participants completed a Go/No-Go task and a Continuous Performance Task with quasi-random MW probes. RESULTS: There were few age-related differences in attentional control. Although MW was not associated with decrements in global performance, local performance measures revealed deleterious effects of MW, which were present across age groups. Older adults reported higher trait mindfulness and less MW than young adults, and these variables helped explain the lack of observed age-related differences in attentional control. CONCLUSIONS: Individual differences in dispositional mindfulness and MW propensity explain important variance in attentional performance across age. Increasing present-moment focus and reducing lapses in attention represent important targets for cognitive rehabilitation interventions. (JINS, 2018, 24, 876-888).

Mindfulness training induces structural connectome changes in insula networks.

Although mindfulness meditation is known to provide a wealth of psychological benefits, the neural mechanisms involved in these effects remain to be well characterized. A central question is whether the observed benefits of mindfulness training derive from specific changes in the structural brain connectome that do not result from alternative forms of experimental intervention. Measures of whole-brain and node-level structural connectome changes induced by mindfulness training were compared with those induced by cognitive and physical fitness training within a large, multi-group intervention protocol (n = 86). Whole-brain analyses examined global graph-theoretical changes in structural network topology. A hypothesis-driven approach was taken to investigate connectivity changes within the insula, which was predicted here to mediate interoceptive awareness skills that have been shown to improve through mindfulness training. No global changes were observed in whole-brain network topology. However, node-level results confirmed a priori hypotheses, demonstrating significant increases in mean connection strength in right insula across all of its connections. Present findings suggest that mindfulness strengthens interoception, operationalized here as the mean insula connection strength within the overall connectome. This finding further elucidates the neural mechanisms of mindfulness meditation and motivates new perspectives about the unique benefits of mindfulness training compared to contemporary cognitive and physical fitness interventions.

Mindfulness Training for Healthy Aging: Impact on Attention, Well-Being, and Inflammation.

The growing interest in mindfulness interventions for use in aging samples has been met with promising evidence of cognitive, emotional, and physiological benefits. The purpose of this review is to provide an overview of the impact of mindfulness training on three areas of functioning in older adults: behavioral and neural correlates of attentional performance, psychological well-being, and systemic inflammation. We have previously proposed that mindfulness training is uniquely suited as a rehabilitative tool for conferring both cognitive and emotional benefits for older adults. Specifically, mindfulness training's promotion of focused attention may mitigate the decline of attentional control abilities across late development and allow older adults to capitalize on their preserved emotion regulation abilities. Existing evidence points to some improvements in facets of attentional control in older adults, although some studies have shown no benefits in performance. Further, there is evidence of enhancements in both psychological and physical aspects of well-being, and accompanying improvements in systemic inflammation, following mindfulness training. The scientific investigation of mindfulness training is still relatively nascent, with only a limited number of studies, particularly randomized controlled trials utilizing active comparison conditions. It will be important for future research to incorporate placebo-controlled comparison groups to clearly establish the causal role of mindfulness practices in promoting holistic health in older adults.

Mindfulness and emotion regulation in older and young adults.

OBJECTIVES: Research shows that dispositional mindfulness is associated with metrics of overall well-being, with enhanced emotion regulation potentially underlying these salutary effects. However, the role of regulation strategy use remains poorly understood. In this study, we examined age-variant associations between dispositional mindfulness, emotion regulation strategies, and emotion dysregulation. METHOD: Self-report data were collected from 50 older and 50 young adults on mindfulness, emotion dysregulation, and recent strategy use. For the current study, we examined if cognitive reappraisal, experiential suppression, and thought avoidance use mediated the association between mindfulness and emotion dysregulation. RESULTS: Thought avoidance, but not reappraisal or suppression strategies, partially mediated the association between mindfulness and emotion dysregulation. Age group moderated the observed mediation, such that for young adults, lower mindfulness was associated with greater use of thought avoidance, and in turn with greater emotion dysregulation (e.g., difficulties engaging in goal-directed behavior in the face of strong emotions). CONCLUSION: The current cross-sectional study suggests that reduced avoidance of thoughts may partially explain the relationship between trait mindfulness and enhanced emotion regulation, with this mediational pathway being stronger for young compared with older adults.

Age-related differences in emotion regulation strategies: Examining the role of contextual factors.

Increasing age is characterized by greater positive affective states. However, there is mixed evidence on the implementation of emotion regulation strategies across the life span. To clarify the discrepancies in the literature, we examined the modulating influence of contextual factors in understanding emotion regulation strategy use in older and young adults. Forty-eight older adults and forty-nine young adults completed a retrospective survey inquiring about the use of emotion regulation strategies in emotion-eliciting situations experienced over the preceding 2 weeks. We used factor analysis to establish clusters of emotion regulation strategies, resulting in cognitive strategies, acceptance, and maladaptive strategies. Overall, we found context-dependent age-related differences in emotion regulation strategy use. Specifically, older adults reported greater use of acceptance than young adults in situations of moderate intensity and in situations that evoke anxiety and sadness. In addition, older adults reported using maladaptive strategies to a lesser extent in high- and moderate-intensity situations and in situations that elicit anxiety and sadness when compared with young adults. There were no age-related differences in the use of cognitive strategies across contexts. Older adults, compared to young adults, reported less use of maladaptive strategies and greater use of acceptance than young adults, which suggests that the enhanced emotional functioning observed later in life may be due to a shift in strategy implementation.

Dispositional mindfulness and the wandering mind: Implications for attentional control in older adults.

Age-related cognitive decline brings decreases in functional status. Dispositional mindfulness, the tendency towards present-moment attention, is hypothesized to correspond with enhanced attention, whereas mind-wandering may be detrimental to cognition. The relationships among mindfulness, task-related and task-unrelated thought, and attentional control performance on Go/No-Go and Continuous Performance tasks were examined in older adults. Dispositional mindfulness was negatively associated with task-unrelated thought and was positively associated with reactive control, but not proactive control or Go/No-Go performance. Although mind-wandering was not directly associated with performance, task-unrelated thought mediated the mindfulness-proactive control relation. Fewer task-unrelated thoughts were associated with lower proactive control. Interestingly, this effect was moderated by working memory such that it was present for those with low-average, but not high, working memory. This study highlights the importance of dispositional mindfulness and mind-wandering propensity in accounting for individual differences in attentional control in older adults, providing important targets for future cognitive remediation interventions.
