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.

What's So Special About Working Memory? An Examination of the Relationships Among Working Memory, Secondary Memory, and Fluid Intelligence

Working memory capacity (WMC) has received attention across many areas of psychology, in part because of its relationship with intelligence. The mechanism underlying the relationship is unknown, but the nature of typical WMC tasks has led to two hypothesized mechanisms: secondary-memory processes (e.g., search and retrieval) and the maintenance of information in the face of distraction. In the present study, participants (N = 383) completed a battery of cognitive tasks assessing processing speed, primary memory, working memory, secondary memory, and fluid intelligence. Secondary memory was the strongest predictor of fluid intelligence and added unique predictive value in models that accounted for working memory. In contrast, after accounting for the variance in fluid intelligence associated with the secondary-memory construct, the working memory construct did not significantly predict variability in fluid intelligence. Therefore, the secondary-memory requirements shared by many memory tasks may be responsible for the relationship between WMC and fluid intelligence, making the relationship less unique than is often supposed.

Dynamic deconstructive psychotherapy versus optimized community care for borderline personality disorder co-occurring with alcohol use disorders: a 30-month follow-up.

Patients having co-occurring borderline personality disorder and alcohol use disorders represent a common, but particularly severe and refractory subgroup. An individual, time-limited treatment, dynamic deconstructive psychotherapy (DDP), has been shown to be effective for this subgroup, but long-term outcomes are not known. Participants were recruited from a sample of 30 patients enrolled in a 12-month randomized controlled trial of DDP versus optimized community care (OCC). Outcomes were assessed after an additional 18 months of naturalistic follow-up. DDP participants received an equivalent amount of individual treatment and less group therapy than those receiving OCC, but demonstrated large, sustained treatment effects over a broad range of outcomes and achieved significantly greater improvement in core BPD symptoms, depression, parasuicide, and recreational drug use over the 30-month study. These results suggest that DDP is a cost-effective treatment that can lead to broad and sustained improvement for the dually diagnosed subgroup.

Age, stress, and emotional complexity: Results from two studies of daily experiences.

Experiencing positive and negative emotions together (i.e., co-occurrence) has been described as a marker of positive adaptation during stress and a strength of socioemotional aging. Using data from daily diary (N = 2,022; ages 33-84) and ecological momentary assessment (N = 190; ages 20-80) studies, we evaluate the utility of a common operationalization of co-occurrence, the within-person correlation between positive affect (PA) and negative affect (NA). Then we test competing predictions regarding when co-occurrence will be observed and whether age differences will be present. Results indicate that the correlation is not an informative indicator of co-occurrence. Although correlations were stronger and more negative when stressors occurred (typically interpreted as lower co-occurrence), objective counts of emotion reports indicated that positive and negative emotions were 3 to 4 times more likely to co-occur when stressors were reported. This suggests that co-occurrence reflects the extent to which negative emotions intrude on typically positive emotional states, rather than the extent to which people maintain positive emotions during stress. The variances of both PA and NA increased at stressor reports, indicating that individuals reported a broader not narrower range of emotion during stress. Finally, older age was associated with less variability in NA and a lower likelihood of co-occurring positive and negative emotions. In sum, these findings cast doubt on the utility of the PA-NA correlation as an index of emotional co-occurrence, and question notion that greater emotional co-occurrence represents either a typical or adaptive emotional state in adults.

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.

Daily verbal and nonverbal expression of osteoarthritis pain and spouse responses.

Summary A daily diary study of osteoarthritis patients and their spouses suggests that nonverbal and verbal channels of pain expression together promote help‐oriented spouse responses and mitigate punishing ones. Abstract The current study applied a model of pain communication to examine the distinction between verbal and nonverbal pain expression in their prediction of punishing, empathic, and solicitous spouse responses to patient pain. It was hypothesized that on days when patients engaged in more nonverbal expression, spouses would respond more positively (ie, with less punishing and more solicitous and empathic behavior). The same pattern was predicted for verbal expression. In addition, it was expected that associations between patient nonverbal pain expression and positive spouse responses would be strengthened, and that the association with punishing responses would be weakened, on days when levels of verbal pain expression were higher than usual, regardless of daily pain severity. In a 22‐day diary study, 144 individuals with knee osteoarthritis and their spouses completed daily measures of pain expression, spouse responses, health, and affect. The predicted positive main effect of nonverbal expression on empathic and solicitous responses was supported by the data, as was the positive main effect for verbal pain expression. Results from moderation analyses partially supported our hypothesis in that patients’ nonverbal pain expression was even more strongly related to empathic and solicitous spouse responses on days of high verbal pain expression, and patients were buffered from spouse punishing responses on days when both nonverbal and verbal expression were high. These findings suggest that pain expression in both verbal and nonverbal modes of communication is important for positive and negative spousal responses.

Intraindividual Coupling of Daily Stressors and Cognitive Interference in Old Age

OBJECTIVES The current study examined emotional and cognitive reactions to daily stress. We examined the psychometric properties of a short cognitive interference measure and how cognitive interference was associated with measures of daily stress and negative affect (NA) between persons and within persons over time. METHODS A sample of 87 older adults (M(age) = 83, range = 70-97, 28% male) completed measures of daily stress, cognitive interference, and NA on 6 days within a 14-day period. RESULTS The measure yielded a single-factor solution with good reliability both between and within persons. At the between-person level, NA accounted for the effects of daily stress on individual differences in cognitive interference. At the within-person level, NA and daily stress were unique predictors of cognitive interference. Furthermore, the within-person effect of daily stress on cognitive interference decreased significantly with age. DISCUSSION These results support theoretical work regarding associations among stress, NA, and cognitive interference, both across persons and within persons over time.

Metallothionein deficiency leads to soleus muscle contractile dysfunction following acute spinal cord injury in mice

Metallothionein (MT) is a small molecular weight protein possessing metal binding and free radical scavenging properties. We hypothesized that MT-1/MT-2 null (MT(-/-)) mice would display exacerbated soleus muscle atrophy, oxidative injury, and contractile dysfunction compared with the response of wild-type (WT) mice following acute spinal cord transection (SCT). Four groups of mice were studied: WT laminectomy, WT transection, MT(-/-) laminectomy (MT(-/-) lami), and MT(-/-) transection (MT(-/-) trans). Laminectomy animals served as surgical controls. Mice in SCT groups experienced similar percent body mass (BM) losses at 7 days postinjury. Soleus muscle mass (MM) and MM-to-BM ratio were lower at 7 days postinjury in SCT vs. laminectomy mice, with no differences observed between strains. However, soleus muscles from MT(-/-) trans mice showed reduced maximal specific tension compared with MT(-/-) lami animals. Mean cross-sectional area (microm(2)) of type I and type IIa fibers decreased similarly in SCT groups compared with laminectomy controls, and no difference in fiber distribution was observed. Lipid peroxidation (4-hydroxynoneal) was greater in MT(-/-) trans vs. MT(-/-) lami mice, but protein oxidation (protein carbonyls) was not altered by MT deficiency or SCT. Expression of key antioxidant proteins (catalase, manganese, and copper-zinc superoxide dismutase) was similar between the groups. In summary, MT deficiency did not impact soleus MM loss, but resulted in contractile dysfunction and increased lipid peroxidation following acute SCT. These findings suggest a role of MT in mediating protective adaptations in skeletal muscle following disuse mediated by spinal cord injury.

Reliability and Validity of Ambulatory Cognitive Assessments

Mobile technologies are increasingly used to measure cognitive function outside of traditional clinic and laboratory settings. Although ambulatory assessments of cognitive function conducted in people’s natural environments offer potential advantages over traditional assessment approaches, the psychometrics of cognitive assessment procedures have been understudied. We evaluated the reliability and construct validity of ambulatory assessments of working memory and perceptual speed administered via smartphones as part of an ecological momentary assessment protocol in a diverse adult sample (N = 219). Results indicated excellent between-person reliability (≥0.97) for average scores, and evidence of reliable within-person variability across measurement occasions (0.41-0.53). The ambulatory tasks also exhibited construct validity, as evidence by their loadings on working memory and perceptual speed factors defined by the in-lab assessments. Our findings demonstrate that averaging across brief cognitive assessments made in uncontrolled naturalistic settings provide measurements that are comparable in reliability to assessments made in controlled laboratory environments.

Associations among Fluid and Crystallized Cognition and Daily Stress Processes in Older Adults

The current study examined associations among fluid and crystallized cognition, and daily stress processes in older adults. Older adults (N = 107) completed measures of daily stressors and affect on six occasions over 2 weeks, as well as measures of fluid and crystallized cognition. Higher crystallized cognition was associated with a greater likelihood of exposure to daily stressors, including arguments and avoided arguments. Higher fluid cognition was associated with diminished emotional reactivity to daily stressors for negative but not positive affect. Discussion focuses on the roles of fluid and crystallized cognition for understanding daily stress processes, daily activity and lifestyle, and health.
