The Wear and Tear of Daily Stressors on Mental Health

Researchers assert that affective responses to seemingly minor daily events have long-term implications for mental health, yet this phenomenon has rarely been investigated. In the current study, we examined how levels of daily negative affect and affective reactivity in response to daily stressors predicted general affective distress and self-reported anxiety and depressive disorders 10 years after they were first assessed. Across eight consecutive evenings, participants (N = 711; age = 25 to 74 years) reported their daily stressors and their daily negative affect. Increased levels of negative affect on nonstressor days were related to general affective distress and symptoms of an affective disorder 10 years later. Heightened affective reactivity to daily stressors predicted greater general affective distress and an increased likelihood of reporting an affective disorder. These findings suggest that the average levels of negative affect that people experience and how they respond to seemingly minor events in their daily lives have long-term implications for their mental health.

Interindividual Differences and Intraindividual Variability in the Cortisol Awakening Response: An Examination of Age and Gender

This article shows age and gender differences in the magnitude and day-to-day variability of the cortisol awakening response (CAR) using a national sample of 1,143 adults who completed the second wave of the National Study of Daily Experiences, a part of the Midlife Development in the United States survey. Participants between the ages of 33 and 84 years completed 8 consecutive nightly interviews and provided 4 saliva samples (upon waking, 30 min after waking, before lunch, and before bed) on 4 consecutive interview days. Results revealed substantial day-to-day variability in the CAR as well as significant AgexGender interactions, indicating that although no systematic age-related differences emerged for women, the magnitude and day-to-day variability of the CAR increased with age among men.

Frontiers in the Use of Biomarkers of Health in Research on Stress and Aging

Assessment of biomarkers that reflect objective indicators of physiological processes has become increasingly popular in psychological research on stress and aging. The current article reviews biomarkers of the neuroendocrine and immune systems, including issues related to measurement and normative age-related changes. We also discuss how exposure to stressors can provoke changes in these biomarkers and propose that stressful experiences may accelerate age-related declines in these systems. We recommend that future research examining physical health and aging incorporate dynamic and multivariate methods for assessing links between stressors and biomarkers.

Associations among daily stressors and salivary cortisol: Findings from the National Study of Daily Experiences

While much research has focused on linking stressful experiences to emotional and biological reactions in laboratory settings, there is an emerging interest in extending these examinations to field studies of daily life. The current study examined day-to-day associations among naturally occurring daily stressors and salivary cortisol in a national sample of adults from the second wave of the National Study of Daily Experiences (NSDE). A sample of 1694 adults (age=57, range=33-84; 44% male) completed telephone interviews detailing their stressors and emotions on eight consecutive evenings. Participants also provided saliva samples upon waking, 30min post-waking, before lunch and before bed, on four consecutive interview days resulting in 5995 days of interview/cortisol data. Analyses revealed three main findings. First, cortisol AUC was significantly higher on stressor days compared to stressor-free days, particularly for arguments and overloads at home, suggesting that daily stressors are associated with increased cortisol output, but that not all daily stressors have such an influence. Second, individuals reporting a greater frequency of stressor days also exhibited a steeper diurnal cortisol slope. Finally, daily stressor-cortisol associations were unaltered after adjustment for daily negative affect and physical symptoms. Our discussion focuses on the influence of naturally occurring daily stressors on daily cortisol and the role of daily diary approaches for studying healthy cortisol responses to psychosocial stressors outside of traditional laboratory settings.

Age and the Association Between Negative Affective States and Diurnal Cortisol

The current study examined age differences in the association between daily negative affect, average negative affect, and diurnal cortisol among participants from the National Study of Daily Experiences (N = 1,423; age range: 33-84 years). Across four consecutive days, participants reported the negative emotions they experienced and provided four saliva samples per day, from which cortisol was assayed. Results revealed that higher levels of average negative affect were associated with greater daily cortisol output (area-under-the-curve, with respect to ground), but only among the older participants in our sample. Higher levels of daily negative affect were also associated with elevated levels of bedtime cortisol, but only among older adults who, on average, reported lower levels of average negative affect. Findings support the theory of strength and vulnerability integration, and underscore the importance of age when examining associations between negative affective states and diurnal cortisol.

The Speedometer of Life: Stress, Health and Aging

Publisher Summary This chapter describes the links between stress, health, and aging; to identify stress processes that lead to changes in key psychological and physiological indicators; and to examine the associations between biological indicators, health, and well-being. These links are based on life-span developmental theory of stress and health that highlights variations and differences within and between individuals as they develop in multidimensional sociohistorical contexts. This chapter provides a broad framework for incorporating the role of stress into the study of health and aging by describing the concepts and measurement of stress processes, life-span and life course perspectives on stressors and their consequences, biomarkers that provide a link between stressors and health, and merging research documenting the effects of stress on cognitive health. There are multiple dimensions of stressors ranging from major life events to chronic stressors to daily hassles. Adult developmental researchers have examined how stressors affect health by assessing intra-individual change in exposure and reactivity to these types of stressors. Research has also begun to document individual and group differences in changes in these stress processes. Much of the psychological literature on stress and aging has assessed affective reactivity, but emerging work has begun to incorporate biological as well as cognitive outcomes of stress processes. These are all important advances in understanding how stress may speed not only biological aging but also cognitive aging.Publisher Summary This chapter describes the links between stress, health, and aging; to identify stress processes that lead to changes in key psychological and physiological indicators; and to examine the associations between biological indicators, health, and well-being.

Age Differences in Emotional Well-Being Vary by Temporal Recall

OBJECTIVE Older adults often appraise and remember events less negatively than younger adults. These tendencies may influence reports that rely more on nonexperiential, reconstructive processes. As such, the current study examined whether age differences may be more pronounced for reports of emotions that span across increasingly longer temporal epochs compared to reports of more proximal emotional experiences. METHOD Participants (aged 25-74 during Burst 1) from the Midlife in the United States Survey and the National Study of Daily Experiences reported the negative affect they experienced across a month, a week, and throughout the day at two measurement bursts 10 years apart. RESULTS Across all negative affect measures, older age was related to lower levels of negative affect. The effect of age, however, varied across the three temporal epochs, such that age differences were smallest when people reported their daily negative affect and greatest when they reported their monthly negative affect. DISCUSSION Taking into account how emotion reports differ based on method provides a more realistic picture of emotional experience in adulthood. Findings suggest that age differences in emotional experiences vary based on whether questions ask about short versus longer time periods. Age advantages are most pronounced when people recall emotions across increasingly longer periods of time.

When Emotional Pain Becomes Physical: Adverse Childhood Experiences, Pain, and the Role of Mood and Anxiety Disorders

OBJECTIVE We examined the association between retrospective reports of adverse childhood experiences (ACEs) and painful medical conditions. We also examined the mediating and moderating roles of mood and anxiety disorders in the ACEs-painful medical conditions relationship. METHOD Ten-year longitudinal data were obtained from the National Comorbidity Surveys (NCS-1, NCS-2; N = 5001). The NCS-1 obtained reports of ACEs, current health conditions, current pain severity, and mood and anxiety disorders. The NCS-2 assessed for painful medical conditions (e.g., arthritis/rheumatism, chronic back/neck problems, severe headaches, other chronic pain). RESULTS Specific ACEs (e.g., verbal and sexual abuse, parental psychopathology, and early parental loss) were associated with the painful medical conditions. Baseline measures of depression, bipolar disorder, and posttraumatic stress disorder were also associated with the number of painful medical conditions. Anxiety and mood disorders were found to partially mediate the ACEs-painful medical conditions relationship. We determined through mediation analyses that ACEs were linked to an increase in anxiety and mood disorders, which, in turn, were associated with an increase in the number of painful medical conditions. We determined through moderation analyses that ACEs had an effect on increasing the painful medical conditions at both high and low levels of anxiety and mood disorders; though, surprisingly, the effect was greater among participants at lower levels of mood and anxiety disorders. CONCLUSION There are pernicious effects of ACEs across mental and physical domains. Dysregulation of the hypothalamic-pituitary-adrenal stress response and the theory of reserve capacity are reviewed to integrate our findings of the complex relationships.

One size fits all? Applying theoretical predictions about age and emotional experience to people with functional disabilities

The current study examined whether commonly observed age differences in affective experience among community samples of healthy adults would generalize to a group of adults who live with significant functional disability. Age differences in daily affect and affective reactivity to daily stressors among a sample of participants with spinal cord injury (SCI) were compared with a noninjured sample. Results revealed that patterns of affective experience varied by sample. Among noninjured adults, older age was associated with lower levels of daily negative affect, higher levels of daily positive affect, and less negative affective reactivity in response to daily stressors. In contrast, among the sample with SCI, no age differences emerged. Findings, which support the model of Strength and Vulnerability Integration, underscore the importance of taking life context into account when predicting age differences in affective well-being.

Age, Daily Stress Processes, and Allostatic Load: A Longitudinal Study

Objective: The present study examined age differences in the association between daily stressors and allostatic load. Method: Participants consisted of 317 adults (34-84 years) who participated in Waves 1 (1996-1997) and 2 (between 2005 and 2009) of the Midlife Development in the United States Survey. During Wave 1, participants reported the stressors they encountered across eight consecutive days. Within-person affective reactivity slopes indexing change in negative affect from a nonstressor day to a stressor day were calculated for each participant. Affective reactivity and stressor exposure scores at Wave 1 were used to predict allostatic load at Wave 2. Results: Heightened levels of affective reactivity at Wave 1 predicted elevated levels of allostatic load at Wave 2 but only among older adults who also reported high levels of stressor exposure. No significant associations emerged for younger adults. Discussion: Daily stress processes may be one pathway through which age-related physical health declines occur.
