The 5-HTTLPR polymorphism in the serotonin transporter gene moderates the association between emotional behavior and changes in marital satisfaction over time

Why do some individuals become dissatisfied with their marriages when levels of negative emotion are high and levels of positive emotions are low, whereas others remain unaffected? Using data from a 13-year longitudinal study of middle-aged and older adults in long-term marriages, we examined whether the 5-HTTLPR polymorphism in the serotonin transporter gene moderates the association between negative and positive emotional behavior (objectively measured during marital conflict) and changes in marital satisfaction over time. For individuals with two short alleles of 5-HTTLPR, higher negative and lower positive emotional behavior at Time 1 predicted declines in marital satisfaction over time (even after controlling for depression and other covariates). For individuals with one or two long alleles, emotional behavior did not predict changes in marital satisfaction. We also found evidence for a crossover interaction (individuals with two short alleles of 5-HTTLPR and low levels of negative or high levels of positive emotion had the highest levels of marital satisfaction). These findings provide the first evidence of a specific genetic polymorphism that moderates the association between emotional behavior and changes in marital satisfaction over time and are consistent with increasing evidence that the short allele of this polymorphism serves as a susceptibility factor that amplifies sensitivity to both negative and positive emotional influences.

Anger and sadness in response to an emotionally neutral film: evidence for age-specific associations with well-being

When the association between emotion and well-being is being considered, positive emotions usually come to mind. However, negative emotions serve important adaptive functions and particular negative emotions may be especially adaptive at different stages of adult development. We examined the associations between self-reported negative emotions in response to an emotionally neutral, thematically ambiguous film and subjective well-being among 76 young (age 20-29), 73 middle-aged (age 40-49), and 73 older (age 60-69) adults. Results indicated that higher self-reported anger in response to the film was associated with higher well-being for middle-aged adults, but not for young and older adults. Higher self-reported sadness in response to the film was associated with higher well-being for older adults, but not for young and middle-aged adults. These findings were stronger for cognitive well-being (i.e., satisfaction with life) than for affective well-being (i.e., ratio of dispositional positive to negative affect) and were specific to these emotions (not found for self-reported disgust or fear) and to the emotionally neutral film (not found for sad or disgusting films). Results are discussed in terms of the functions that anger and sadness are thought to serve and the control opportunities afforded in midlife and late life that render these functions differentially adaptive.

Greater sadness reactivity in late life

Although previous research suggests that overall emotional reactivity does not change with normal aging, it is possible that different emotions follow different developmental courses. We examined emotional reactivity to films selected to elicit sadness, disgust, and a neutral state in young, middle-aged and older adults (total N = 222). Physiology and expressive behavior were measured continuously and reports of subjective emotional experience were obtained following each film. Results indicated that older adults reported greater sadness in response to all films and greater physiological responses to the sadness film than did the younger age groups. There were no age differences found in self-reported disgust or in behavioral expressions of sadness or disgust in response to any film. The age differences that were found were maintained even after controlling for pre-film self-reported sadness and for personal experiences of loss. These findings support the notion that sadness reactivity is heightened with age.

Relationship satisfaction and emotional language in frontotemporal dementia and Alzheimer disease patients and spousal caregivers

We studied the impact of 2 types of dementia on marital satisfaction and on the emotional language that spouses use during conflictive marital interactions. Fifteen frontotemporal dementia (FTD) and 16 Alzheimer disease (AD) patient-caregiver couples, and 21 control couples, discussed a relationship problem in a laboratory setting. Marital satisfaction was assessed through questionnaire, and emotion language was quantified using text analysis. FTD couples reported lower marital satisfaction than AD and control couples. During the interactions, FTD and AD caregivers used significantly more negative emotion words than their patient spouses (no spousal differences were found in control couples). FTD caregivers also used more negative words than AD caregivers and controls. We interpret these findings as reflecting challenges that the behavioral changes in FTD create for maintaining a healthy marital bond.

We can work it out: age differences in relational pronouns, physiology, and behavior in marital conflict

This study examined the relationship that personal pronouns spoken during a marital conversation have with the emotional qualities of those interactions and with marital satisfaction. Middle-aged and older couples (N = 154) engaged in a 15-min conflict conversation during which physiology and emotional behavior were continuously monitored. Verbatim transcripts of the conversations were coded into 2 lexical categories: (a) we-ness (we-words), pronouns that focus on the couple; (b) separateness (me/you-words), pronouns that focus on the individual spouses. Analyses revealed that greater we-ness was associated with a number of desirable qualities of the interaction (lower cardiovascular arousal, more positive and less negative emotional behavior), whereas greater separateness was associated with a less desirable profile (more negative emotional behavior, lower marital satisfaction). In terms of age differences, older couples used more we-ness words than did middle-aged couples. Further, the associations between separateness and marital satisfaction were strongest for older wives. These findings indicate that the emotional aspects of marital quality are expressed in the natural language of couples engaged in conversation.
