Emotional stress-reactivity and positive affect among college students: the role of depression history

Association of stress and emotional well-being in non-medical college students: A systematic review and meta-analysis

Stress among college students is a well-explored area with profound implications for their emotional well-being. Despite extensive research, the literature presents inconsistent and mixed findings regarding its relationship with emotional well-being, particularly focusing on medical students. Moreover, there is no meta-analytic study to address this inconsistency. To bridge these gaps, this study conducts a systematic review and meta-analysis to explore the nuanced association between stress among non-medical college students and their emotional well-being. The systematic review utilized databases: PubMed, Scopus, and Web of Science, search engine: Google Scholar, and gray literature sources: ProQuest and Research Gate. The dataset consisted of 46 eligible studies (k), comprising 26,214 participants across 20 countries. The mean age was 21.86 (k = 32), with females constituting 60 % (k = 45). The majority of studies employed a cross-sectional/correlational design. The estimated pooled correlation is found to be -0.27 (95 % CI: -0.33, -0.21, p < .01; I2 = 97.5 %, k = 46). Subgroup analysis revealed significant influences of the type of stress (p < .01), emotional well-being (p < .01), tools (p < .01) used, significance status of findings (p < .001), and demographic factors - country (p < .001) and income level (p < .05). The study found an inversely significant and moderate association between stress and emotional well-being in non-medical college students, consistent with existing literature. Significant moderation by study and demographic variables suggests substantial heterogeneity among studies, highlighting potential influences from demographics, methodologies, and populations.

Mindfulness as an early intervention for hazardous alcohol use among non-treatment seeking Latine emerging adults: A mini-review

The age cohort referred to as emerging adults (ages 18-29 years old) demonstrates the most hazardous alcohol use in the United States (U.S.) Approximately one-third of emerging adults regularly engage in heavy episodic drinking (4/5 drinks in two hours females/males). Compared to their non-Latine White peers, Latine emerging adults in the U.S. report lower rates of heavy episodic drinking (HED) yet are at greater risk of developing a substance use disorder and experience more severe negative consequences from drinking alcohol. Despite their high-risk status, Latine emerging adults are less likely to seek treatment and have less access to innovative health-promoting resources, further exacerbating health inequities. Research has shown that practicing mindfulness can interrupt habituated cognitions, intrusive thinking, and automatic behaviors associated with hazardous drinking. However, Latine representation in MBI trials is minimal. This mini-review explores the potential value of mindfulness as an early intervention for hazardous alcohol use among Latine emerging adults. The review provides future directions for research, highlighting the need to design culturally and developmentally tailored MBIs that can provide a respectful, non-judgmental, and discrimination-free environment that appeals to Latine emerging adults. Additionally, conclusions are drawn regarding the possible benefits of pairing MBI with contingency management strategies to decrease attrition rates in MBI trials.

Depression and academic engagement among college students: the role of sense of security and psychological impact of COVID-19

Background

The negative consequences of depression in college students have garnered global attention, especially in relation to academic achievement during the COVID-19 pandemic, which need critical assessment.

Aim

This study investigated whether a sense of security mediated the relationship between depression and academic engagement among college students during the pandemic and whether the moderating psychological impact of COVID-19 has a moderating effect on this relationship.

Methods

In this cross-sectional study, we recruited 466 college students from 30 provincial-level administrative regions in China via the Internet and used established scales to measure depression, academic engagement, a sense of security, and the psychological impact of COVID-19. The mediating and moderating effects were tested using the bootstrap method.

Results

Depression was found to negatively influence academic engagement, with a sense of security partially mediating this relationship. Moreover, the psychological impact of COVID-19 was shown to have a moderating effect on this mediating process.

Conclusion

This study could aid in crafting pertinent strategies to mitigate the adverse effects of depression on learning amid unexpected public health crises and foster better mental health among college students.

Investigating associations between physical activity, stress experience, and affective wellbeing during an examination period using experience sampling and accelerometry

Previous studies reported that physical activity could buffer the negative association of psychological stress with affective wellbeing. However, the studies that examined this relation in everyday life have assessed physical activity only by self-report but not with objective measures such as accelerometry. We therefore investigated the associations of both subjectively and objectively measured physical activity with stress experiences and affective wellbeing. A total of 90 university students participated in a 10-day experience sampling and diary study during their examination period and reported about stress experiences, physical activity, and affective states. Physical activity was additionally assessed using accelerometry in 50 of the participants. Subjectively assessed physical activity and objectively assessed light physical activity were associated with feeling less stressed in the evening. Also, light physical activity during the day was associated with a smaller increase/higher decrease in feeling stressed from morning to evening. The association of stress experience with negative affect was moderated by objective light physical activity. No interactive effects of stress intensity and physical activity on affective wellbeing were found. On stressful days, physical activity may buffer the negative association between stress and affective wellbeing. Particularly light physical activity as assessed with accelerometry seems to play an important role. It may be beneficial for students' affective wellbeing to increase or at least maintain physical activity during examination periods.

The mediating effect of stress reactivity in the 18-year bidirectional relationship between generalized anxiety and depression severity

BACKGROUND

Generalized anxiety disorder (GAD) and major depressive disorder (MDD) often precede and predict one another. Heightened stress reactivity may be a mediation mechanism underlying the long-term connections between GAD and MDD. However, cross-sectional studies on this topic have hindered directional inferences.

METHOD

The present study examined stress reactivity as a potential mediator of the sequential associations between GAD and MDD symptoms in a sample of 3,294 community-dwelling adults (M age = 45.6, range = 20-74). Participants completed three waves of measurement (T1, T2, and T3) spaced nine years apart. GAD and MDD symptom severity were assessed at T1, T2, and T3 (Composite International Diagnostic Interview-Short Form). Stress reactivity (Multidimensional Personality Questionnaire) was measured at T2.

RESULTS

Structural equation mediation modeling demonstrated that higher T1 GAD symptoms positively predicted more severe T3 MDD symptoms via T2 stress reactivity, controlling for T1 MDD (d = 0.45-0.50). However, T2 stress reactivity was not a significant mediator in the relationship between T1 MDD severity and T3 GAD symptoms after controlling for T1 GAD. Direct effects indicated that T1 GAD positively predicted T3 MDD 18 years later and vice versa (d = 1.29-1.65).

LIMITATIONS

Stress reactivity was assessed using a self-report measure, limiting conclusions to perceived (vs. physiologically indexed) stress reactivity.

CONCLUSIONS

These findings indicate that stress reactivity may be one mechanism through which GAD leads to later MDD over prolonged durations. Overall, results suggest that targeting stress reactivity in treatments for GAD may reduce the risk of developing subsequent MDD.

Dismissing Attachment and Global and Daily Indicators of Subjective Well-Being: An Experience Sampling Approach

The present research examined whether a dismissing attachment style (i.e., being high in attachment avoidance and low in attachment anxiety) is a risk factor for low subjective well-being (SWB). Specifically, we examined the associations between dismissing attachment and two indicators of SWB: global life satisfaction and daily affect. Self-reports of attachment and overall life satisfaction were collected from 257 adults at an initial lab session. Afterward, experience sampling methodology was used to gather repeated measures of positive and negative affect, as well as social context, from the sample for 8 days. Our findings indicate that, on average, dismissing people reported fairly modest levels of overall life satisfaction. Moreover, they experienced relatively low levels of both negative affect and positive affect across the 8-day study period. Overall, our results suggest that dismissing people have a "muted" or dull emotional life.

Association of Covid-19 pandemic-related stress and depressive symptoms among international medical students

BACKGROUND

The outbreak of Covid-19 had negative impacts on the mental stress and induced psychological distress among university students worldwide. This study proposed a moderated mediation model, and hypothesized that the Covid-19 pandemic-related stress was positively related to depressive symptoms among international medical students.

METHODS

An online survey on stress and depressive symptoms of international students was conducted in a medical university. Questions on Covid-19 pandemic-related stress, Patient Health Quesionnaire-9, Simplified Coping Style Questionnaire and the Perceived Social Support Scale were used as measurements, and model analyses were conducted using Hayes' PROCESS macro for SPSS.

RESULTS

It was found that 9.83%, 3.08% and 2.12% students had mild, moderate and severe depressive symptoms, respectively, and the positive association between Covid-19 pandemic-related stress and depressive symptoms was significant (β = 0.27, t = 6.87, P < 0.01). Negative coping was also significantly correlated to depressive symptoms (β = 0.26, t = 6.60, P < 0.01), and partially mediated the association between Covid-19 pandemic-related stress and depressive symptoms. Perceived social support had a negative association with depressive symptoms (β=-0.26, t=-6.25, P < 0.01), played a negative moderating role in the relationship between negative coping and depressive symptoms, and moderated the indirect effect of Covid-19 pandemic-related stress on depressive symptoms via negative coping.

CONCLUSIONS

Results of the study suggested that under the background of continuing pandemic, intervention or prevention of mental health problem is urgently needed for the international students, and depression may be alleviated through reducing negative coping and increasing perceived social support.

Do positive and negative emotional reactions during war predict subsequent symptomatology? A prospective experience sampling study

While peritraumatic negative emotions have been associated with subsequent posttraumatic stress and depression, the predictive role of real-time emotional reactions to specific stressors during prolonged stress exposure is still unclear, particularly that of positive emotions. The current study uses experience sampling methodology to examine individual general levels of negative and positive emotions, and emotional reactivity to specific stressors during war, as prospective predictors of posttraumatic stress and depression. Ninety-six civilians exposed to rocket fire during the 2014 Israel-Gaza war reported exposure to rocket warning sirens and levels of ten negative and six positive emotions twice a day for 30 days. Symptoms of posttraumatic stress and depression were then assessed two months post-war. Participants reported higher negative emotions and lower positive emotions during assessment windows with sirens. Over time, negative emotions decreased and positive emotions increased. Higher levels of overall negative emotions predicted posttraumatic stress symptoms and depression symptoms two months later. Levels of positive emotions, and negative and positive emotional reactivity to sirens, were not associated with subsequent symptomatology. Our results indicate the stronger role of overall negative emotions as predictors of symptomatology compared with momentary emotional reactivity, and the stronger predictive role of negative compared with positive emotions.

Acute stress reduces reward-related neural activity: Evidence from the reward positivity

Stress and blunted reward processing are risk factors for Major Depressive Disorder (MDD). The experience of acute stress reduces fMRI correlates of reward-related neural activity; however, few studies have examined how acute stress impacts measures of reward derived from event-related potentials (ERPs). The current study examined the impact of an acute stressor on the Reward Positivity (RewP), an ERP that indexes reward sensitivity, in twenty-six college students. Participants completed a monetary reward task while they placed their left hand in cold water set at 13 °C (i.e. acute stress condition) and again while their hand was placed in room temperature water (i.e. control condition). These conditions were separated by one week and performed in a counter-balanced order across participants. The results revealed that the RewP amplitude was blunted in the acute stress condition compared to the control condition. Moreover, there was a trend toward this effect interacting with self-reported depressive symptoms: the RewP was reduced only among individuals who reported low depressive symptoms. The current study suggests that an acute stressor reduces the RewP, and that this effect might be moderated by current depressive symptoms. Future studies might examine the temporal association between reward processing and stress, and how they interact to predict depressive symptoms.LAY SUMMARYThe current study examined the impact of acute stress on the brain's reward system. The results indicated that acute stress reduced activity within the brain's reward system, particularly among individuals with low depressive symptoms.

BMI status and associations between affect, physical activity and anxiety among U.S. children during COVID-19

BACKGROUND

There is concern regarding how the COVID-19 pandemic may impact the psychological and physical health of children, but to date, studies on mental health during the pandemic in children are limited. Furthermore, unprecedented lifestyle stressors associated with the pandemic may aggravate the childhood obesity epidemic, but the role of BMI on child activity levels and psychological outcomes during COVID-19 is unknown.

OBJECTIVES

We investigated how emotional responses (positive/negative affect), physical activity (PA) and sedentary behaviours related to anxiety among U.S. children with healthy weight and overweight/obesity during the pandemic.

METHODS

Sixty-four typically developing children (63% girls, 53% healthy weight) aged 9 to 15 years completed two virtual visits during the height of 'stay-at-home' measures from April 22 to July 29, 2020. Children completed 24-hours PA recalls, state portion of State-Trait Anxiety Inventory for Children and the 10-item Positive and Negative Affect Schedule for Children.

RESULTS

Independent of child BMI status, child anxiety scores were over five standard deviations greater than normative values from paediatric populations prior to the pandemic. Higher positive affect and PA were each associated with reduced anxiety levels in children with overweight/obesity, whereas higher positive affect was associated with reduced anxiety in children with healthy weight. Greater leisure screen time was associated with higher negative affect irrespective of child BMI status.

CONCLUSIONS

These associations highlight the potential mental health benefits of maintaining positive affect, engaging in PA and limiting leisure screen time for children during the pandemic and suggest that these associations may be particularly relevant for children with overweight/obesity.

Emotional reactivity to war stressors: An experience sampling study in people with and without different psychiatric diagnoses

There is a lack of knowledge regarding real-time emotional reactivity to high-intensity stressors, particularly in people with mental illness, a potentially vulnerable population. The current study aimed to examine negative emotional reactions to recurring high-intensity stressors within a continuous war situation, in people with different psychiatric diagnosis types. Experience sampling method was used to examine emotional reactions among 143 civilians exposed to rockets during the 2014 Israel-Gaza war, of them 18.2% with psychosis, 14.7% with anxiety or depression and 67.1% without mental illness. Participants reported exposure to rocket warning sirens and the levels of 10 negative emotions twice a day for 30 days. Negative emotional levels were higher on most emotions following high-intensity stressors (sirens), that is, emotional reactivity was demonstrated in real-time during war. Overall, no difference in reactivity was found among the three study groups. Moreover, people with anxiety/depression were less reactive than people without mental illness on sadness and being overwhelmed. The findings indicate similar and sometimes lower emotional reactivity to high-intensity stressors in people with mental illness compared to the general population. Nevertheless, people with mental illness seem to have significant emotional needs during war, to be addressed in prevention and intervention efforts.

Reduced positive affect on days with stress exposure predicts depression, anxiety disorders, and low trait positive affect 7 years later

Positive emotions serve important functions for mental health. Susceptibility to reduced positive emotions in the context of stress may increase risk for poor mental health outcomes, including anxiety and depressive disorders and low overall levels of positive emotion. In an 8-day daily diary study within a larger panel study (N = 1,517), we tested whether degree of reduction in time spent experiencing positive affect on days of stress exposure predicted lower levels of positive affect and elevated risk for major depressive and anxiety disorders (generalized anxiety disorder or panic disorder) 7 years later. Bayesian multilevel structural equation modeling controlling for overall levels of affect, stress exposure, leisure time, sex, age, and past year diagnoses of depression and anxiety disorders was conducted. Participants, on average, reported less time experiencing positive affect on days with stressors compared to days without stressors. In addition, participants varied in the extent to which their time spent experiencing positive affect differed across days with and without stressors. Those who reported an especially reduced proportion of the day experiencing positive affect on days with stressors also experienced lower positive affect and greater risk for major depressive disorder and anxiety disorders 7 years later. These prospective associations suggest that between-person differences in the within-person association between stress and positive emotions have implications for mental health years later. The efficacy of preventive interventions could be improved by fostering resilience of positive emotions during common stressful events. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Associations between Affect, Physical Activity, and Anxiety Among US Children During COVID-19

We investigated how emotional responses (positive and negative affect), physical activity (PA), and sedentary behaviors related to anxiety among US children during the COVID-19 pandemic. Sixty-four typically-developing children (63% girls) age 9–15 years old completed two virtual visits during height of “stay-at-home” measures between April 22 – July 29, 2020. Children completed 24-hour PA recalls, state portion of State-Trait Anxiety Inventory for Children (STAIC), and the shortened 10-item Positive and Negative Affect Schedule for Children (PANAS-C). Children reported state anxiety scores that were more than 5 standard deviations greater than values from healthy pediatric populations prior to the pandemic. Children with higher positive affect and who reported more time in PA reported less state anxiety. Sedentary and leisure screen time were positively correlated with negative affect. Our findings suggest that maintaining positive affect, engaging in PA, and limiting leisure screen time may be important for child mental health during stressful periods.

Interpersonal Stress Severity Longitudinally Predicts Adolescent Girls' Depressive Symptoms: the Moderating Role of Subjective and HPA Axis Stress Responses

In recent decades, stress response models of adolescent depression have gained attention, but it remains unclear why only certain adolescents are vulnerable to the depressogenic effects of stress while others are not. Building on evidence that affective and physiological responses to stress moderate the impact of stress exposure on depression, the current study examined whether the interaction between severity of interpersonal stress, subjective affective reactivity, and hypothalamic-pituitary-adrenal (HPA) axis reactivity to an acute, in-vivo psychosocial stressor prospectively predicted depressive symptoms nine months later. Hypotheses were examined with a clinically-oversampled group of 182 adolescent girls (aged 12-16) to ensure an examination of the widest possible range of risk. Self-report measures of affect and salivary cortisol samples were collected before and after an in-vivo stress task to assess affective reactivity and HPA axis reactivity, respectively. Severity of interpersonal stress between baseline and nine months was assessed using a semi-structured interview and was objectively coded for severity and content theme (i.e., interpersonal vs. non-interpersonal). Results indicate that experiences of severe interpersonally-themed stress predict elevated levels of depressive symptoms longitudinally only for adolescent girls with elevated affective reactivity to stress, and suggest that these deleterious effects of stress are most exacerbated for girls with elevated physiological responses to stress. Findings suggest that it may be critical to examine both affective and physiological stress responses when assessing risk for depression in adolescents.

Negative affect reactivity to stress and internalizing symptoms over the transition to college for Latinx adolescents: Buffering role of family support

Affect reactivity to stress may play a role in the development of internalizing symptoms during the college transition, a critical developmental juncture for Latinx adolescents, the largest ethnic minority group on college campuses. This study examined whether affect reactivity during high school is associated with internalizing symptoms in college and explored two potential protective factors, perceived family and peer support. Participants were 209 Latinx adolescents (Mage = 18.10; 64.4% female) who completed standard surveys and four diary assessments per day over 7 days (N > 4,500 momentary observations). First, to measure affect reactivity, we assessed whether perceived stress was associated with negative affect at the momentary level during high school (senior year). Second, we tested whether affect reactivity predicted internalizing symptoms during the first year of college. Third, we tested whether perceived family or peer support buffered the negative consequences of affect reactivity. Results indicated statistically significant within- and between-person associations between stress and negative affect. Moreover, affect reactivity significantly predicted depressive, but not anxiety, symptoms. Buffering was found for family, but not peer, support. Findings extend previous research by detecting associations between momentary affect reactivity and internalizing symptoms during a sociocultural shift in Latinx adolescents' lives and have implications for culturally appropriate programs to prevent depressive symptoms.

Disruption of Neural Homeostasis as a Model of Relapse and Recurrence in Late-Life Depression

The significant public health burden associated with late-life depression (LLD) is magnified by the high rates of recurrence. In this manuscript, we review what is known about recurrence risk factors, conceptualize recurrence within a model of homeostatic disequilibrium, and discuss the potential significance and challenges of new research into LLD recurrence. The proposed model is anchored in the allostatic load theory of stress. We review the allostatic response characterized by neural changes in network function and connectivity and physiologic changes in the hypothalamic-pituitary-adrenal axis, autonomic nervous system, immune system, and circadian rhythm. We discuss the role of neural networks' instability following treatment response as a source of downstream disequilibrium, triggering and/or amplifying abnormal stress response, cognitive dysfunction and behavioral changes, ultimately precipitating a full-blown recurrent episode of depression. We propose strategies to identify and capture early change points that signal recurrence risk through mobile technology to collect ecologically measured symptoms, accompanied by automated algorithms that monitor for state shifts (persistent worsening) and variance shifts (increased variability) relative to a patient's baseline. Identifying such change points in relevant sensor data could potentially provide an automated tool that could alert clinicians to at-risk individuals or relevant symptom changes even in a large practice.

Between vulnerability and resilience: A network analysis of fluctuations in cognitive risk and protective factors following remission from depression

Research exploring how cognitive risk- and protective factors relate following remission from internalizing disorders suggests a central role for resilience. However, it remains unclear what constitutes resilience in this context. Furthermore, previous studies have typically relied on cross-sectional data which do not allow to map the temporal dynamics of such relations. Using a seven-day experience sampling period in 85 remitted depressed patients, we examined the interplay between five transdiagnostic vulnerability- and protective factors in daily life. We present a temporal, contemporaneous, and a between-subjects network, providing an in-depth analysis of how these factors relate to daily life fluctuations in residual symptomatology. Furthermore, we test the role of positive affect as a main resilience factor. Resilience uniquely predicted all other factors over time (temporal network). Higher levels of resilience were related to less momentary use of rumination, more deployment of positive appraisal, and lower occurrence of residual symptoms (contemporaneous network). Participants scoring high on resilience mostly engaged in positive appraisal (between-subjects network). Similar structures were obtained when substituting self-reported resilience by positive affect. This highlights the importance of resilience, and in particular, positive affectivity, to cope with stressors following remission. This may be fostered by facilitating the use of positive appraisal.

Prevalence and predictors of violent victimization in remitted patients with recurrent depression

BACKGROUND

Depressed patients are at increased risk to fall victim to a violent crime compared to the general population. It remains unknown whether their increased risk persists after remission. This study compared victimization rates of remitted patients with both a random general population sample and a group of currently depressed patients. Furthermore, this study aimed to identify predictors of future violent victimization.

METHODS

In this longitudinal study conducted in the Netherlands, 12-month prevalence rates of sexual assaults, physical assaults, and threats were assessed with the Safety Monitor in 140 currently remitted patients with recurrent depression, and compared to those of a weighted general population sample (N = 9.175) and a weighted sample of currently depressed outpatients (N = 102) using Chi-square tests. Logistic regression analyses were performed to identify baseline predictors of future victimization.

RESULTS

The prevalence of violent victimization did not differ between remitted patients and the general population (12.1 vs. 11.7%). Remitted patients were significantly less likely to have been victimized over the past 12 months than currently depressed patients (12.1 vs. 35.5%). In remitted patients, living alone and low sense of mastery at baseline predicted future violent victimization. However, when combined in a multiple model, only living alone was independently associated with violent victimization (χ² = 16.725, df = 2, p < .001, R² = 0.221).

LIMITATIONS

Our comparison of victimization rates across samples was cross-sectional.

CONCLUSIONS

Since the increased risk of victimization appears to be specific for the acute depressive state, preventive interventions should target victimization in currently depressed patients.

Dispositional negativity in the wild: Social environment governs momentary emotional experience

Dispositional negativity-the tendency to experience more frequent or intense negative emotions-is a fundamental dimension of temperament and personality. Elevated levels of dispositional negativity have profound consequences for public health and wealth, drawing the attention of researchers, clinicians, and policymakers. Yet, relatively little is known about the factors that govern the momentary expression of dispositional negativity in the real world. Here, we used smart phone-based experience-sampling to demonstrate that the social environment plays a central role in shaping the moment-by-moment emotional experience of 127 young adults selectively recruited to represent a broad spectrum of dispositional negativity. Results indicate that individuals with a more negative disposition derive much larger emotional benefits from the company of close companions-friends, romantic partners, and family members-and that these benefits reflect heightened feelings of social connection and acceptance. These results set the stage for developing improved interventions and provide new insights into the interaction of emotional traits and situations in the real world, close to clinically and practically important end-points.

Independent and relative effects of stress, depressive symptoms, and affect on college students' daily health behaviors

Stress and depressive symptoms are associated with maladaptive health behavior practices such as unhealthy eating, sedentary behavior, insufficient sleep, and substance use. The relative and interactive effects of stress and depressive symptoms on health behavior practices are less well understood. The present study examined these processes in a daily diary study of 127 college students. Results from hierarchical generalized linear models indicated that depressive symptoms, and chronic and daily stress, but not acute stressful life events, were significantly associated with a composite score of daily maladaptive health behavior engagement (depressive symptoms b = .01, SE= .00, p < .01; chronic stress, b = .03, SE= .01, p < .01; daily stress, b = .01, SE= .01, p = .02); unexpectedly, the effect of stress on health behaviors was not moderated by depressive symptoms. Additionally, results demonstrated that the effect of depressive symptoms on health behaviors was mediated by fluctuations in daily negative affect. These results bear implications for intervention during a crucial period in the development of mental and physical health.

Effects of stress management and relaxation training on the relationship between diabetes symptoms and affect among Latinos

OBJECTIVE

Stress management and relaxation (SMR) interventions can reduce symptoms of chronic disease and associated distress. However, there is little evidence that such interventions disrupt associations between symptoms and affect. This study examined whether SMR dampened the link between symptoms of hyperglycemia and proximal levels of affect. We predicted that during periods of increased hyperglycemia, individuals receiving SMR training, relative to controls, would demonstrate smaller increases in negative affect.

DESIGN

Fifty-five adult Latinos with type 2 diabetes were randomised to either one group session of diabetes education (DE-only; N = 23) or diabetes education plus eight group sessions of SMR (DE + SMR; N = 32). After treatment, participants reported five diabetes symptoms and four affective states twice daily for seven days using a bilingual telephonic system.

RESULTS

Mean age = 57.8 years, mean A1c = 8.4%, and ¾ was female with less than a high school education. Individuals receiving DE + SMR, compared to DE-only, showed a weaker positive within-person association between daily diabetes symptoms and nervous affect. Groups also differed on the association between symptoms and enthusiasm. Age moderated these associations in most models with older individuals showing less affect reactivity to symptoms.

CONCLUSIONS

Findings provide partial support for theorised mechanisms of SMR.

Work-Family Conflict and Mental Health Among Female Employees: A Sequential Mediation Model via Negative Affect and Perceived Stress

After the implementation of the universal two-child policy in 2016, more and more working women have found themselves caught in the dilemma of whether to raise a baby or be promoted, which exacerbates work-family conflicts among Chinese women. Few studies have examined the mediating effect of negative affect. The present study combined the conservation of resources model and affective events theory to examine the sequential mediating effect of negative affect and perceived stress in the relationship between work-family conflict and mental health. A valid sample of 351 full-time Chinese female employees was recruited in this study, and participants voluntarily answered online questionnaires. Pearson correlation analysis, structural equation modeling, and multiple mediation analysis were used to examine the relationships between work-family conflict, negative affect, perceived stress, and mental health in full-time female employees. We found that women's perceptions of both work-to-family conflict and family-to-work conflict were significant negatively related to mental health. Additionally, the results showed that negative affect and perceived stress were negatively correlated with mental health. The 95% confidence intervals indicated the sequential mediating effect of negative affect and stress in the relationship between work-family conflict and mental health was significant, which supported the hypothesized sequential mediation model. The findings suggest that work-family conflicts affected the level of self-reported mental health, and this relationship functioned through the two sequential mediators of negative affect and perceived stress.

Associations Between Daily Affective Instability and Connectomics in Functional Subnetworks in Remitted Patients with Recurrent Major Depressive Disorder

Remitted patients with major depressive disorder (rMDD) often report more fluctuations in mood as residual symptomatology. It is unclear how this affective instability is associated with information processing related to the default mode (DMS), salience/reward (SRS), and frontoparietal (FPS) subnetworks in rMDD patients at high risk of recurrence (rrMDD). Sixty-two unipolar, drug-free rrMDD patients (⩾2 MDD episodes) and 41 healthy controls (HCs) were recruited. We used experience sampling methodology to monitor mood/cognitions (10 times a day for 6 days) and calculated affective instability using the mean adjusted absolute successive difference. Subsequently, we collected resting-state functional magnetic resonance imaging data and performed graph theory to obtain network metrics of integration within (local efficiency) the DMS, SRS, and FPS, and between (participation coefficient) these subnetworks and others. In rrMDD patients compared with HCs, we found that affective instability was increased in most negative mood/cognition variables and that the DMS had less connections with other subnetworks. Furthermore, we found that rrMDD patients, who showed more instability in feeling down and irritated, had less connections between the SRS and other subnetworks and higher local efficiency coefficients in the FPS, respectively. In conclusion, rrMDD patients, compared with HCs, are less stable in their negative mood and these dynamics are related to differences in information processing within- and between-specific functional subnetworks. These results are a first step to gain a better understanding of how mood fluctuations in real life are represented in the brain and provide insights into the vulnerability profile of MDD.

Adiposity moderates links from early adversity and depressive symptoms to inflammatory reactivity to acute stress during late adolescence

Both early adversity and depression are associated with heightened inflammation. However, few studies have focused on inflammatory reactivity to psychosocial stress and examined adiposity as a potential moderator. Yet, repeated heightened inflammatory reactivity over time is thought to contribute to low-grade chronic inflammation and adipose tissue is a key source of pro-inflammatory cytokines. The purpose of the present study was to examine whether early adversity and depressive symptoms were related to stress-induced inflammation and whether these associations varied by total body and abdominal adiposity as measured by body mass index (BMI) and waist circumference (WC) in a sample of late adolescents. Participants reported on their early family environment and current depressive symptoms, had their height, weight, and WC assessed for adiposity markers, and provided blood samples for IL-6 assessment before and after a standardized laboratory stress task. No main effect of early adversity on IL-6 reactivity to acute stress was observed. However, significant interactions between early adversity and BMI and WC emerged. Greater exposure to early adversity was associated with greater IL-6 responses only among adolescents with higher BMI or WC. The same pattern of findings was observed for depressive symptoms. Additionally, moderated mediation analyses indicated that among adolescents with greater adiposity, early adversity indirectly influenced IL-6 reactivity via current depressive symptoms. These findings contribute to our understanding of vulnerability factors that may amplify the associations between early adversity and depressive symptoms and inflammation during relatively early stages of life.

The cortisol:C-reactive protein ratio and negative affect reactivity in depressed adults

OBJECTIVE

We evaluated the effect of the cortisol (CORT) to high sensitivity C-reactive protein (hsCRP) ratio on stress-induced negative affect (NA) reactivity and whether the association was moderated by depressive symptom severity and gender. The CORT/CRP ratio was used to evaluate the integrity of the negative feedback loop between the hypothalamic-pituitary-adrenal axis and inflammatory response system.

METHOD

Basal CORT and hsCRP levels were measured in fasting blood samples from 198 medication-free and nonsmoking healthy men and women. Depressive symptom severity was assessed using the Hamilton Rating Scale for Depression (HAMD). NA ratings were collected at baseline and at the completion of the laboratory stressors, the Anger Recall Interview (ARI) and reading.

RESULTS

Adjusting for potential confounders and baseline NA, analysis revealed a significant relationship between CORT/CRP ratio and NA reactivity to ARI as a function of depressive symptom severity. Simple effects revealed that for participants with high HAMD, decreasing CORT/CRP ratio, suggestive of an insufficient CORT release relative to higher hsCRP, predicted increasing stress-induced NA reactivity. For participants with low HAMD, the CORT/CRP ratio failed to predict NA reactivity. Gender did not moderate the joint effect of depressive symptom severity and the CORT/CRP ratio on stress-induced NA reactivity.

CONCLUSIONS

This is the first study to document that a premorbid dysregulation of the neuro-immune relationship, characterized by an insufficient release of CORT in conjunction with higher CRP, plays a role in stress sensitivity, and specifically NA reactivity, in individuals with elevated levels of depression symptoms.

Affect and Condom Use Among Men Who have Sex with Men: A Daily Diary Study

Men who have sex with men (MSM) are disproportionally affected by HIV. Although some theoretical models created to explain why individuals engage in risky sexual behavior contain an affective component, there has been relatively little focus on the influence of affect on sexual risk-taking. The goal of this study is to investigate the association between affect and condom use among MSM using an archival dataset from a survey of users of a popular sex-oriented website. Multilevel modeling was used to analyze daily diary data from 2871 MSM. At the within-person level, positive affect was positively related to condomless anal sex (CAS), whereas negative affect was negatively related to CAS. However, these results were qualified by interactions of trait affect and relationship to sex partner. These findings suggest that interventions focused on emotional regulation may have the potential to reduce CAS among MSM.

The role of affect in predicting depressive symptomatology in remitted recurrently depressed patients

BACKGROUND

Major depressive disorder is an emotional disorder. It is important to improve our understanding of the role of affect in relapse/recurrence of depression. Therefore, this study examines whether affect plays a role in prospectively predicting depressive symptomatology and if there are indications for emotional scarring as a consequence of undergoing depressive episodes.

METHODS

In 107 patients remitted from recurrent depression affect was examined in predicting depressive symptomatology as measured with the Inventory of Depressive Symptomatology - Self Report. Affect was measured with the Positive and Negative Affect Schedule and with a one item Visual Analogue Mood Scale. Indication of emotional scarring was examined by comparing number of previous depressive episodes to levels of affect.

RESULTS

Less positive affect as assessed after remission predicted increased depressive symptomatology six months later, even after we controlled for baseline symptomatology. Negative affect also predicted depressive symptomatology six months later, but not after controlling for baseline depressive symptomatology. No relationship was found between affect and number of previous episodes.

LIMITATIONS

All participants in this study had two or more previous depressive episodes and received CBT during the acute phase of their depression. The instruments that measured mood and affect were administered within 4 weeks of each other.

CONCLUSIONS

Positive affect and negative affect as assessed after remission in recurrent depression can predict depressive symptomatology. Especially positive affect seems to play an independent role in predicting depressive symptomatology. Directly targeting positive affect in relapse prevention during remission might be a way to enhance treatment effects.

Daily emotional stress reactivity in emerging adulthood: temporal stability and its predictors

BACKGROUND & OBJECTIVES

Emotional reactivity to stress is associated with both mental and physical health and has been assumed to be a stable feature of the person. However, recent evidence suggests that the within-person association between stress and negative affect (i.e., affective stress-reactivity) may increase over time and in times of high stress, at least in older adult populations. The objective of the current study was to examine the across-time stability of stress-reactivity in a younger sample - emerging adulthood - and examine neuroticism, overall stress, social support and life events as potential moderators of stability.

DESIGN & METHODS

Undergraduate students (N = 540, mean age = 18.76 years) participated in a measurement burst design, completing a 30-day daily diary annually for four years. Moderators were assessed once at every burst, while negative affect and stress were assessed daily via a secure website.

RESULTS & CONCLUSIONS

Findings suggest a relatively high degree of rank-order and mean-level stability in stress-reactivity across the four years, and within-person changes in neuroticism and overall stress predicted concurrent shifts in stress-reactivity. Unlike older samples, there was no evidence of an overall linear change in stability over time, though there was significant variability in linear change trajectories.

Episode-specific drinking-to-cope motivation and next-day stress-reactivity

BACKGROUND

Research consistently shows drinking-to-cope (DTC) motivation is uniquely associated with drinking-related problems. We furthered this line of research by examining whether DTC motivation is predictive of processes indicative of poor emotion regulation. Specifically, we tested whether nighttime levels of episode-specific DTC motivation, controlling for drinking level, were associated with intensified affective reactions to stress the following day (i.e. stress-reactivity).

DESIGN AND METHODS

We used a micro-longitudinal design to test this hypothesis in two college student samples from demographically distinct institutions: a large, rural state university (N = 1421; 54% female) and an urban historically Black college/university (N = 452; 59% female).

RESULTS

In both samples the within-person association between daily stress and negative affect on days following drinking episodes was stronger in the positive direction when previous night's drinking was characterized by relatively higher levels of DTC motivation. We also found evidence among students at the state university that average levels of DTC motivation moderated the daily stress-negative affect association.

CONCLUSIONS

Findings are consistent with the notion that DTC motivation confers a unique vulnerability that affects processes associated with emotion regulation.

Factors contributing to depressive mood states in everyday life: A systematic review

BACKGROUND

Although accumulated evidence suggests that fluctuations in depressed mood are common among individuals with depression, and may be associated with onset, duration, and severity of illness, a systematic appraisal of putative predictors of depressed mood is lacking.

METHODS

A systematic search for relevant studies in the literature was conducted using PsycInfo and PubMed databases via EbscoHost in February 2016. The search was limited to articles using the experience sampling method, an approach suitable for capturing in situ fluctuations in mood states.

RESULTS

Forty-two studies met inclusion criteria for the review, from which three key risk factors (poor sleep, stress, and significant life events) and two protective factors (physical activity and quality of social interactions) were identified. The majority of papers supported concurrent and lagged associations between these putative protective/risk factors and depressed mood.

LIMITATIONS

Despite support for each of the proposed protective/risk factors, few studies evaluated multiple factors in the same study. Moreover, the time course for the effects of these predictors on depressed mood remains largely unknown.

CONCLUSIONS

The present review identified several putative risk and protective factors for depressed mood. A review of the literature suggests that poor sleep, negative social interactions, and stressful negative events may temporally precede spikes in depressed mood. In contrast, exercise and positive social interactions have been shown to predict subsequent declines in depressed mood. However, the lack of multivariate models in which the unique contributions of various predictors could be evaluated means that the current state of knowledge prevents firm conclusions about which factors are most predictive of depressed mood. More complex modeling of these effects is necessary in order to provide insights useful for clinical treatment in daily life of the depressed mood component of depressive disorders.

The interplay between cognitive risk and resilience factors in remitted depression: A network analysis

BACKGROUND

Individuals in remission from depression are at increased risk for developing future depressive episodes. Several cognitive risk- and resilience factors have been suggested to account for this vulnerability. In the current study we explored how risk- and protective factors such as cognitive control, adaptive and maladaptive emotion regulation, residual symptomatology, and resilience relate to one another in a remitted depressed (RMD) sample.

METHODS

We examined the relationships between these constructs in a cross-sectional dataset of 69 RMD patients using network analyses in order to obtain a comprehensive, data-driven view on the interplay between these constructs. We subsequently present an association network, a concentration network, and a relative importance network.

RESULTS

In all three networks resilience formed the central hub, connecting perceived cognitive control (i.e., working memory complaints), emotion regulation, and residual symptomatology. The contribution of the behavioral measure for cognitive control in the network was negligible. Moreover, the directed relative importance network indicates bidirectional influences between these constructs, with all indicators of centrality suggesting a key role of resilience in remission from depression.

LIMITATIONS

The presented findings are cross-sectional and networks are limited to a fixed set of key constructs in the literature pertaining cognitive vulnerability for depression.

CONCLUSIONS

These findings indicate the importance of resilience to successfully cope with stressors following remission from depression. Further in-depth studies will be essential to identify the specific underlying resilience mechanisms that may be key to successful remission from depression.

The impact of maternal, child, and family characteristics on the daily well-being and parenting experiences of mothers of children with autism spectrum disorder

This study utilized a daily diaries method to explore the global factors that impact daily general affect and daily parenting interactions of mothers of children with autism spectrum disorder. Eighty-three mothers of a child with autism spectrum disorder between the ages of 3 and 13 years completed global assessments of maternal depressive symptoms, child autism spectrum disorder symptom severity, and family functioning. Mothers then reported on their daily negative and positive affect as well as their daily positive and frustrating parenting interactions for 14 consecutive days. The results indicated that higher levels of maternal depressive symptoms were related to decreased daily positive affect, whereas greater child social motivation impairments were related to increased daily positive affect. Only maternal depressive symptoms were associated with increased daily negative affect. Furthermore, higher levels of family cohesion were related to increased daily positive parenting interactions. Finally, higher maternal depressive symptoms as well as family rigidity were related to increased daily frustrating parenting interactions. Implications for interventions focused on the family system are discussed.
