Regret intensity, diurnal cortisol secretion, and physical health in older individuals: Evidence for directional effects and protective factors.

Two studies were conducted to examine the associations between life regrets and health-relevant variables among older adults. Study 1 explored whether intense experiences of regret would be associated with a health-relevant biological process (i.e., diurnal cortisol secretion) and acute physical problems (N = 183). In Study 2, a group of 103 older adults was followed over a period of 3 months, and changes in cold symptoms and sleep problems were examined. Study 2 incorporated an experimental manipulation, targeted at engaging participants in adaptive social- cognitive processes through writing. The results of Study 1 showed intense life regrets to be associated with a larger volume and a steeper morning rise of cortisol secretion and with higher levels of acute physical symptoms. Study 2 demonstrated that levels of regret intensity generally declined only in the experimental group, whereas certain aspects of regret intensity remained stable in the control group. In addition, the intervention evidenced a beneficial effect on the association between initial regret intensity and increased sleep problems over time.

Fibromyalgia: The role of sleep in affect and in negative event reactivity and recovery.

Objective: Fibromyalgia (FM) syndrome is a chronic pain condition characterized by diffuse muscle pain, increased negative mood, and sleep disturbance. Until recently, sleep disturbance in persons with FM has been modeled as the result of the disease process or its associated pain. The current study examined sleep disturbance (i.e., sleep duration and sleep quality) as a predictor of daily affect, stress reactivity, and stress recovery. Design and Measures: A hybrid of daily diary and ecological momentary assessment methodology was used to evaluate the psychosocial functioning of 89 women with FM. Participants recorded numeric ratings of pain, fatigue, and positive and negative affect 3 times throughout the day for 30 consecutive days. At the end of each day, participants completed daily diary records of positive and negative life events. In addition, participants reported on their sleep duration and sleep quality each morning. Results: After accounting for the effects of positive events, negative events, and pain on daily affect scores, it was found that sleep duration and quality were prospectively related to affect and fatigue. Furthermore, the effects of inadequate sleep on negative affect were cumulative. In addition, an inadequate amount of sleep prevented affective recovery from days with a high number of negative events. Conclusions: These results lend support to the hypothesis that sleep is a component of allostatic load and has an upstream role in daily functioning.

Daily stress, cortisol, and sleep: The moderating role of childhood psychosocial environments.

Objective: The purpose of this study was to explore whether childhood family environments moderated the relation between daily stress and daily biological outcomes (sleep, cortisol output) in healthy young adults. Design: There were 87 participants, ages 19 to 25 who provided information on characteristics of their childhood family environment (conflict, parental warmth). Main Outcome Measures: For 1 week they completed a daily stress checklist via electronic diary, provided salivary cortisol samples 4 times a day, and wore an Actiwatch to measure sleep (minutes, efficiency). Data was analyzed using hierarchical linear modeling. Results: Family risk significantly moderated the relation between daily number of stressors and sleep minutes (b = ?12.10, p = .02), such that the more difficult one's childhood environment, the less sleep individuals got on days in which they experienced a greater number of stressors. Parental warmth moderated the relation between stress severity and cortisol output (b = ?0.19, p = .04), such that the less parental warmth individuals received during childhood, the more cortisol they secreted on days that they experienced more severe stress. Conclusions: The childhood psychosocial environment may have long-term effects on biological responses to daily stress, creating vulnerability to disease in individuals from difficult childhoods.

Children's objective and subjective sleep disruptions: Links with afternoon cortisol levels.

Objective: The purpose of this study was to determine possible relations between the quality and amount of children's sleep and cortisol in healthy children. Design: Children's sleep was monitored with actigraphs for 7 nights. Children came to the laboratory to provide saliva samples, which were used to assess cortisol. Children reported on their sleepiness and sleep/wake problems. Sixty-four healthy children participated (M = 8.75 years; SD = .55). Main Outcome Measures: Self-reported sleepiness and sleep/wake problems, actigraphy-measured total sleep minutes, sleep efficiency, minutes awake after sleep onset, and sleep activity, and afternoon cortisol levels. Results: After controlling for demographic variables and child characteristics, higher levels of cortisol were related to increased subjective sleep problems and objective measures of shorter sleep duration and poorer sleep quality. Conclusion: These findings are of importance for understanding critical facets of children's health and well-being, and are noteworthy given the high prevalence of sleep disruptions in otherwise normally developing children in the United States.

The role of awakening cortisol and psychological distress in diurnal variations in affect: A day reconstruction study.

People often feel unhappy in the morning but better later in the day, and this pattern may be amplified in the distressed. Past work suggests that one function of cortisol is to energize people in the morning. In a study of 174 students, we tested to see whether daily affect patterns, psychological distress, and awakening cortisol levels were interlinked. Affect levels were assessed using the Day Reconstruction Method and psychological distress was measured using the Depression Anxiety Stress Scales. On average, positive affect increased markedly in a linear pattern across the day, whereas negative affect decreased linearly. For the highly distressed, this pattern was stronger for positive affect. Lower than average morning cortisol, as assessed by two saliva samples at waking and two samples 30 min after waking, predicted a clear increasing pattern of positive affect throughout the day. When we examined the interlinkages between affect patterns, distress, and cortisol, our results showed that a pronounced linear increase in positive affect from morning through to evening occurred chiefly among distressed people with below average cortisol levels upon awakening. Psychological distress, although not strongly associated with morning cortisol levels, does appear to interact with cortisol levels to profoundly influence affect.

Neuroendocrine regulation and physical and relational aggression: The moderating roles of child maltreatment and gender.

The purpose of the present investigation was to examine the association between circadian rhythms of cortisol and physical and relational aggression. Morning arrival, prelunch, and afternoon predeparture salivary cortisol were assessed among 418 maltreated and nonmaltreated children (52% maltreated; 49% female) attending a summer day camp. Counselors and peers rated participants' involvement in physically and relationally aggressive behaviors. Results indicated that physical aggression was associated with heightened cortisol following morning arrival and relatively steep declines in cortisol over the day, whereas relational aggression was associated with low cortisol following morning arrival and blunted diurnal change in cortisol. Moreover, maltreatment was a significant moderator of this relationship such that aggression was related to greater cortisol dysregulation among nonmaltreated than among maltreated children. The findings suggest that physiological correlates of aggression may differ for physical and relational forms of aggression and among maltreated versus nonmaltreated populations.

Longitudinal changes in cortisol secretion and conversion to psychosis in at-risk youth.

Elevations in hypothalamic–pituitary–adrenal (HPA) axis activity have been implicated in the origins and exacerbation of mental disorders. Several lines of investigation suggest HPA activity, indexed by increased cortisol, is elevated in patients with schizophrenia and other psychotic disorders. This study examined the relation of cortisol levels and longitudinal changes with psychotic outcomes in at-risk adolescents. Participants were 56 adolescents who met risk criteria for psychosis, namely, schizotypal personality disorder (n = 5), prodromal symptom criteria based on the Structured Interview for Prodromal Symptoms (n = 17), or both (n = 34). Of these, 14 subsequently met DSM–IV criteria for an Axis I psychotic disorder (schizophrenia, schizoaffective disorder, or mood disorder with psychotic features). Participants were assessed at baseline and then followed longitudinally. Salivary cortisol was sampled multiple times at initial assessment, interim follow-up, and 1-year follow-up. Area under the curve (AUC) was computed from the repeated cortisol measures. The findings indicate that at-risk subjects who subsequently developed psychosis showed significantly higher cortisol at the first follow-up, a trend at the 1-year follow-up, and a significantly larger AUC when compared to those who did not convert. A similar pattern of group differences emerged from analyses excluding those who may have converted prior to the 1-year follow-up. These findings converge with previous reports on HPA activity in psychosis, as well as theoretical assumptions concerning the effects of cortisol elevations on brain systems involved in psychotic symptoms. Future research with larger samples is needed to confirm and extend these results. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Coping and physical health during caregiving: The roles of positive and negative affect.

The associations among coping, mood, and health variables were examined prospectively over 2 years in 86 HIV positive (HIV+) and 167 HIV negative (HIV-) gay men undergoing the stress of AIDS-related caregiving. Path models suggested that including both positive and negative mood and the men's associated coping strategies increases understanding of why some people suffer adverse health effects during times of stress. Among the HIV- caregivers, higher levels of social coping predicted increases in positive affect, which in turn resulted in lower levels of physical symptoms. In contrast, higher levels of cognitive avoidance predicted increases in negative affect, which in turn resulted in higher levels of physical symptoms. Self-injurious forms of avoidance coping predicted higher levels of physical symptoms independent of mood among the HIV+ caregivers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Long-term follow-up of physical activity behavior in older adults.

Objective: To examine the contribution of social-cognitive factors (self-efficacy and affect) in predicting long-term physical activity in a sample of older adults (N = 174). Design: A prospective design assessed physical activity and psychosocial variables at 2 and 5 years following a 6-month randomized, controlled exercise trial. Main Outcome Measures: The primary outcome variable was self-reported physical activity, with previous behavior, self-efficacy, and affect assessed as determinants of physical activity. Results: Covariance modeling analyses indicated that physical activity at Year 2 was the strongest predictor of physical activity at 5-year follow-up. Both self-efficacy and affect at Year 2 were also associated with physical activity at Year 5, as was original treatment condition. Variables accounted for 35% of the variance in Year 5 activity. Conclusion: Older adults with higher levels of physical activity, more positive affect, and higher self-efficacy at Year 2 were more likely to continue to be active at Year 5. This study is one of the longest follow-ups of exercise behavior in older adults and has implications for structuring environments to maximize the maintenance of physical activity.

Information processing and negative affect: Evidence from the 2003 Health Information National Trends Survey.

Objective: Health communication can help reduce the cancer burden by increasing processing of information about health interventions. Negative affect is associated with information processing and may be a barrier to successful health communication. Design and Main Outcome Measures: We examined associations between negative affect and information processing at the population level. Symptoms of depression (6 items) and cancer worry (1 item) operationalized negative affect; attention to health information (5 items) and cancer information-seeking experiences (6 items) operationalized information processing. Results: Higher cancer worry was associated with more attention to health information (p     

Moderators and mediators of exercise-induced objective sleep improvements in midlife and older adults with sleep complaints.

Objective: Exercise can improve sleep quality, but for whom and by what means remains unclear. We examined moderators and mediators of objective sleep improvements in a 12-month randomized controlled trial among underactive midlife and older adults reporting mild/moderate sleep complaints. Methods: Participants (N = 66, 67% women, 55–79 years) were randomized to moderate-intensity exercise or health education control. Putative moderators were gender, age, physical function, self-reported global sleep quality, and physical activity levels. Putative mediators were changes in BMI, depressive symptoms, and physical function at 6 months. Objective sleep outcomes measured by in-home polysomnography were percent time in Stage I sleep, percent time in Stage II sleep, and number of awakenings during the first third of sleep at 12 months. Results: Baseline physical function and sleep quality moderated changes in Stage I sleep; individuals with higher initial physical function (p = .01) and poorer sleep quality (p = .03) had greater improvements. Baseline physical activity level moderated changes in Stage II sleep (p = .04) and number of awakenings (p = .01); more sedentary individuals had greater improvements. Decreased depressive symptoms (CI:-1.57 to ?0.02) mediated change in Stage I sleep. Decreased depressive symptoms (CI:-0.75 to ?0.01), decreased BMI (CI:-1.08 to ?0.06), and increased physical function (CI: 0.01 to 0.72) mediated change in number of awakenings. Conclusions: Initially less active individuals with higher initial physical function and poorer sleep quality improved the most. Affective, functional, and metabolic mediators specific to sleep architecture parameters were suggested. These results indicate strategies to more efficiently treat poor sleep through exercise in older adults. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Sleep deprivation in adolescents and adults: Changes in affect.

The present study investigated the impact of sleep deprivation on several aspects of affective functioning in healthy participants selected from three different developmental periods: early adolescence (ages 10–13), midadolescence (ages 13–16), and adulthood (ages 30–60). Participants completed an affective functioning battery under conditions of sleep deprivation (a maximum of 6.5 hours total sleep time on the first night followed by a maximum of 2 hours total sleep time on the second night) and rest (approximately 7–8 hours total sleep time each night for two consecutive nights). Less positive affect was observed in the sleep-deprived, compared to rested, condition. This effect held for 9 of the 12 positive affect items on the PANAS-C. Participants also reported a greater increase in anxiety during a catastrophizing task and rated the likelihood of potential catastrophes as higher when sleep deprived, relative to when rested. Early adolescents appraised their main worry as more threatening when sleep deprived, relative to when rested. These results support and extend previous research underscoring the adverse affective consequences of sleep deprivation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The effects of physical fitness and feeling vigorous on self-rated health.

Objective: We prospectively studied the hypothesized beneficial effects of feeling vigorous and of objective physical fitness (gauged based on functional capacity) on subsequently assessed self-rated health (SRH), controlling for possible confounders known to be precursors of SRH and of our predictors. We also investigated the reverse-causation hypothesis that SRH predicts subsequent vigor and functional capacity. Design: Participants were apparently healthy employees (N = 779) who underwent a routine health check at two points of time, Time 1 (T1) and Time 2 (T2), about 18 months apart. We used regression analysis, predicting T2 SRH by T1 SRH, the control variables, and T1vigor and functional capacity. Main Outcome Measures: Vigor was assessed using the Shirom-Melamed Vigor Measure; objective physical fitness was indicated by functional capacity following a treadmill exercise, and self-rated health was measured by a single item. Results: As hypothesized, we found that the change in T2 SRH was positively predicted by T1 vigor, functional capacity, and their interactive term. Testing the reverse causation paths, we found that T1 SRH did not predict subsequent functional capacity and was a relatively weak predictor of subsequent vigor. Conclusion: The affective state of vigor and objectively assessed functional capacity interact to predict subsequent changes in self-rated health.

Age differences in psychosocial predictors of positive and negative affect: A longitudinal investigation of young, midlife, and older adults.

[Correction Notice: An erratum for this article was reported in Vol 26(2) of Psychology and Aging (see record 2011-11703-002). Contains an error in Figure 3, on page 649. The correction discusses where to find the correct data.] Research has consistently shown that despite aging-related losses, older adults have high levels of emotional well-being relative to those in young and midlife adults. We aimed to contribute to knowledge around the factors that predict emotional well-being over the life course by examining age group differences in associations of positive and negative social exchanges and mastery beliefs with positive and negative affect in a sample of 7,472 young, midlife, and older adults assessed on 2 measurement occasions, 4 years apart. Results from structural equation models indicated lower levels of negative affect with advancing age. Mastery was consistently related to higher well-being, with the strongest associations evident for young adults. Older adults reported the most frequent positive and least frequent negative social exchanges; however, associations of social relations with affect tended to be stronger among young and midlife adults relative to older adults. Results are discussed in the context of life course perspectives on goal orientations and self-regulatory processes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Negative affect and self-report of physical symptoms: Two longitudinal studies of older adults.

The ability of negative affect (NA) to predict somatic complaints 6 months later was examined. State NA, including anxious affect (AA) and depressive affect (DA), was measured in 2 separate samples of older adults averaging 62 and 73 years of age. In the first study, DA reliably predicted later complaints, and a corresponding trend was noted for NA. The second study showed that state NA and its 2 constituent variables predicted somatic complaints associated with acute illness (e.g., colds) 6 months later. The second study also examined trait measures of the 3 predictor variables and found that NA and AA, but not DA, were associated with subsequent somatic complaints. However, these trait effects were less robust than those attributable to their state counterparts. The authors conclude that negative mood states are the more consistent predictors of later physical symptom reports. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Seeming ambivalent, being prejudiced: The moderating role of attitude basis on experienced affect.

One experiment examined the potential for ambivalence toward the outgroup based on cognitive but not affective information to be functional to justify the prior expression of prejudice. To this end, the (prejudice expression vs. no prejudice expression) context of holding ambivalence toward the outgroup was manipulated before assessing all participants' cognitively based ambivalence and affectively based ambivalence toward the outgroup. Finally, all participants self-reported their positive affect. As predicted, participants whose prejudice was previously assessed, exhibited increased levels of positive affect to the extent that they were cognitively but not affectively ambivalent toward the outgroup. By contrast, replicating prior work, participants whose prejudice was not previously assessed exhibited decreased levels of positive affect to the extent that they were both cognitively and affectively ambivalent toward the outgroup. Consistent with recent, functional approaches to the conceptualization of attitude structure and prejudice, these findings provide direct evidence that cognitively based ambivalence toward the outgroup can contribute to the need to be prejudicial. The implications of these findings for ambivalence and intergroup research are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Physical health problems, depressive mood, and cortisol secretion in old age: Buffer effects of health engagement control strategies.

Objective: This study examined the protective role played by control behaviors aimed at overcoming physical health problems (health engagement control strategies; HECS) in the associations between older adults' physical health problems, depressive mood, and diurnal cortisol secretion. It was expected that adaptive levels of HECS would buffer the adverse effects of physical health problems on depressive mood and diurnal cortisol secretion. Design and Measures: Physical health problems and HECS were measured in a cross-sectional sample of 215 community-dwelling older adults. In addition, participants' depressive mood and patterns of diurnal cortisol secretion were assessed across 3 days. Results: The findings demonstrate that physical health problems predicted high levels of depressive mood and diurnal cortisol secretion, but only among older adults who reported low levels of HECS (and not among older adults who reported high levels of HECS). Moreover, depressive mood completely mediated the buffering effect of HECS on the association between physical health problems and cortisol secretion. Conclusion: The results suggest that adaptive levels of HECS represent a psychological mechanism that can protect older adults from experiencing the adverse emotional and biological consequences of physical health problems.

The impact of interpersonal violence in adulthood on women's job satisfaction and productivity: The mediating roles of mental and physical health.

Objective: With growing awareness of the prevalence of interpersonal violence victimization among women, research has begun to examine the impact of these experiences on employment. To date, much of this work in the United States has centered on low-income women moving from public assistance to paid employment and research gaps in our understanding of a broader range of working women's experiences still exist. The present study explored the impact of multiple types of victimization (sexual violence, physical intimate partner violence, psychological abuse, and stalking) on a range of work outcomes (job satisfaction, job benefits, job interference). Method: A random-digit-dial telephone survey of 1,079 women living in New Hampshire was conducted. Measures included questions about victimization in adulthood and current perceptions of employment. Results: A multivariate analysis of variance and regression analyses showed clear links between victimization experiences and negative work outcomes. Mental and physical health symptoms represent important mediators explaining these links. Conclusion: Results support the need for workplace policies and supports that provide safety nets for survivors and encourages the development of community norms that assist survivors in accessing such supports.

The nonconscious cessation of goal pursuit: When goals and negative affect are coactivated.

Extending on the recent investigation into the implicit affective processes underlying motivation and decision making, 5 studies examined the role of negative affect in moderating goal priming effects. Specifically, experimental effects on measures that typify motivational qualities of goal systems, such as keeping a goal at a heightened level of mental accessibility and exerting effort to work for a goal and experiencing desire to attain the goal, showed that the motivation and resultant operation of social goals cease when these goals are primed in temporal proximity of negatively valenced information. These goal cessation effects resulting from the mere coactivation of a goal and negative affect are discussed against the background of present research on nonconscious goal pursuit and the role of accessibility and desirability in the regulation of automatic goal-directed behavior.

Associations among perceptions of social support, negative affect, and quality of sleep in caregivers and noncaregivers.

The authors used structural equation modeling to examine associations among perceptions of negative affect, social support, and quality of sleep in a sample of caregivers (n = 175) and noncaregiver control participants (n = 169). The authors hypothesized that caregiver status would be related to sleep quality directly and also indirectly by way of negative affect and social support. This hypothesis was partially supported in that caregiving was found to be indirectly related to sleep quality. However, after accounting for the indirect effects of negative affect and social support, the direct effect of caregiving on sleep quality was no longer statistically significant. The structural model accounted for approximately 43% of the variance in sleep quality. The present findings may be useful in the development of successful sleep interventions for caregivers.
