Alexithymia and Executive Function in Younger and Older Adults

Objective: Alexithymia is associated with adverse mental and physical health outcomes. Determining neuropsychological factors associated with alexithymia may aid in elucidating its underlying mechanisms and identifying treatment targets. Accumulating evidence indicates that executive dysfunction may co-occur with alexithymia in younger adults (YA). However, research on this link in older adults (OA), who may be at greater risk for alexithymia, is scant. This study determined associations between alexithymia and executive function (EF) in healthy younger and OA. Alexithymia was predicted to be associated with poorer EF in both age-groups. Method: Younger (n = 65, aged 18–30; 46% female) and OA (n = 44, aged 61–92; 73% female) completed the 20-item Toronto Alexithymia Scale, three EF tasks (Verbal Fluency, Design Fluency, and Trail Making), measures of memory and verbal IQ, and a self-report measure of depressive symptoms. Three EF composites were created to assess verbal EF, visuospatial EF, and global EF. Results: Greater alexithymia and difficulty describing feelings were associated with poorer verbal EF in OA (p = .02 and p = .005, respectively) but not in YA (ps > .05). The other neuropsychological measures were not significantly associated with alexithymia in regression analyses. Conclusions: Findings are consistent with previous research identifying links between EF and alexithymia. The association between alexithymia and verbal EF may be due to shared prefrontal circuitry involved in emotion regulation. Results provide insight into possible origins of emotion self-awareness deficits in OA.

Emotion Regulation and Memory: Differential Associations in Younger and Midlife/Older Adults

Background/Study Context: Older adults may devote more cognitive resources to the processing and regulation of emotion stimuli than younger adults, but no studies have determined associations between episodic memory performance and naturalistic emotion recovery in a mixed-age sample. The current study ascertained if episodic memory scores were associated with emotion recovery in younger and midlife/older adults and if these associations were moderated by age. Methods: Participants watched a montage of film clips about interpersonal loss. Self-reported negative and positive emotions were assessed prior to the video, immediately after, and again 10 min after the video. Executive functions, processing speed, and episodic memory were assessed. Results: Participants with better episodic memory recovered more quickly from the mood induction than participants with lower scores. Age moderated the association between joviality recovery and memory. Specifically, there was a significantly stronger, positive association between joviality recovery and memory in midlife/older adults relative to younger adults. Conclusions: Stronger memory may facilitate emotion recovery, and this may be particularly true for older adults. Older adults with memory impairment may be at risk for emotion dysregulation.

Perceptions of emotion and age among younger, midlife, and older adults

ABSTRACT Objectives: Older adults report greater emotional well-being than younger persons, yet negative stereotypes about aging are pervasive. Little is known about age group perceptions of emotion in adulthood, particularly for familiar persons. Thus, this project determined perceptions of general affect in familiar younger and older adults. Method: In two studies, participants (Study 1, younger adult n = 123, older adult n = 43; Study 2, younger adult n = 34, midlife adult n = 41, older adult n = 16) provided self-report data about their affect in general, as well as reported on the affect of a familiar younger person (aged 18--34) and a familiar older person (aged 65 or older). Emotion scales assessed high- and low-arousal positive and negative affect. Results: Results suggest a less favorable perception of emotion experiences of older adults compared to younger adults. Specifically, participants of all age groups rated older adults as having lower positive emotions and higher negative emotions than is found in self-report data. Conclusion: Perceptions of emotion in older adulthood reflect stereotypes of negative functioning. Older adult participants were not immune to holding negative views about older adults. Negative perceptions about emotion experiences in later life may be detrimental to the physical and mental health of older adults.

Judgment and classification of emotion terms by older and younger adults

ABSTRACT Objectives: Theoretical models of adult development suggest changes in emotion systems with age. This study determined how younger and older adults judged and classified 70 emotion terms that varied in valence and arousal, and that have been used in previous studies of adult aging and emotion. The terms were from the Positive and Negative Affect Schedule – Expanded (PANAS-X) and the (KS) affect scales. Method: Older (n = 32) and younger adults (n = 111) engaged in a card sort task which determined how the 70 emotion terms were classified (i.e. grouped) in relation to one another. Activation and valence ratings of emotion terms were collected. Results: There were 17 age group differences in item ratings for activation and 19 for valence. Older adults tended to rate emotion terms and scales as more positive and activating than younger persons. Card sort data indicated similarity in conceptualizations of emotion terms across groups with exceptions for serene, sad, and lonely. Conclusions: Research that utilizes self-report emotion data from older and younger persons should consider how perceptions of emotion terms may vary systematically with age. The constructs of sadness, loneliness, and serene may be age-variant and necessitate age-based adjustments in assessment and intervention. Further, older adults may perceive some emotion terms to be more activating and positive than younger persons.

Apathy, alexithymia, and depressive symptoms: Points of convergence and divergence

This study determined convergence and divergence in the constructs of alexithymia, apathy, and depressive symptoms. Understanding of similarities and differences between these constructs will improve diagnostic accuracy for clinical and research purposes. Community-dwelling participants (N=622, M age=35.6 years, SD=13.1) completed online measures of alexithymia, depression, and apathy; 12.2% were alexithymic, 37.8% reported significant depressive symptoms, and 24.9% reported significant apathy. Exploratory Factor Analyses (EFAs) determined the best factor structure for the apathy, alexithymia, and depressive symptoms was comprised of three factors and accounted for 45.1% of item variance. The Depression, Apathy, and Alexithymia factors were defined most strongly by item content that is at the core of each construct. Depression was defined most highly by items assessing sadness, low self-esteem, and loneliness. The strongest item loadings for Alexithymia were difficulty identifying and describing feelings. Apathy was characterized by poor motivation, low interest, and lack of initiative. However, each of these core and defining features had significant cross-loadings on one of the other two factors. Negative affect shared variance with Apathy, low motivation shared variance with Depression, and difficulty describing and identify feelings shared variance with Depression and Apathy. Clinical and research implications are discussed.

Older and younger adults differently judge the similarity between negative affect terms

ABSTRACT Objectives: Theoretical models of aging suggest changes across the adult lifespan in the capacity to differentiate emotions. Greater emotion differentiation is associated with advantages in terms of emotion regulation and emotion resiliency. This study utilized a novel method that directly measures judgments of affect differentiation and does not confound affective experience with knowledge about affect terms. Theoretical predictions that older adults would distinguish more between affect terms than younger persons were tested. Method: Older (n = 27; aged 60–92) and younger (n = 56; aged 18–32) adults rated the difference versus similarity of 16 affect terms from the Kessler and Staudinger (2009) scales; each of the 16 items was paired with every other item for a total of 120 ratings. Participants provided self-reports of trait emotions, alexithymia, and depressive symptoms. Results: Older adults significantly differentiated more between low arousal and high arousal negative affect (NA) items than younger persons. Depressive symptoms were associated with similarity ratings across and within valence and arousal. Conclusion: Findings offer partial support for theoretical predictions that older adults differentiate more between affect terms than younger persons. To the extent that differentiating between negative affects can aid in emotion regulation, older adults may have an advantage over younger persons. Future research should investigate mechanisms that underlie age group differences in emotion differentiation.

A Web-Disseminated Self-Help and Peer Support Program Could Fill Gaps in Mental Health Care: Lessons From a Consumer Survey

Background Self-guided mental health interventions that are disseminated via the Web have the potential to circumvent barriers to treatment and improve public mental health. However, self-guided interventions often fail to attract consumers and suffer from user nonadherence. Uptake of novel interventions could be improved by consulting consumers from the beginning of the development process in order to assess their interest and their preferences. Interventions can then be tailored using this feedback to optimize appeal. Objective The aim of our study was to determine the level of public interest in a new mental health intervention that incorporates elements of self-help and peer counseling and that is disseminated via a Web-based training course; to identify predictors of interest in the program; and to identify consumer preferences for features of Web-based courses and peer support programs. Methods We surveyed consumers via Amazon’s Mechanical Turk to estimate interest in the self-help and peer support program. We assessed associations between demographic and clinical characteristics and interest in the program, and we obtained feedback on desired features of the program. Results Overall, 63.9% (378/592) of respondents said that they would try the program; interest was lower but still substantial among those who were not willing or able to access traditional mental health services. Female gender, lower income, and openness to using psychotherapy were the most consistent predictors of interest in the program. The majority of respondents, although not all, preferred romantic partners or close friends as peer counselors and would be most likely to access the program if the training course were accessed on a stand-alone website. In general, respondents valued training in active listening skills. Conclusions In light of the apparent public interest in this program, Web-disseminated self-help and peer support interventions have enormous potential to fill gaps in mental health care. The results of this survey can be used to inform the design of such interventions.
