The perils of murky emotions: Emotion differentiation moderates the prospective relationship between naturalistic stress exposure and adolescent depression

Readdressing the Ongoing Challenge of Missing Data in Youth Ecological Momentary Assessment Studies: Meta-Analysis Update

BACKGROUND

Ecological momentary assessment (EMA) is pivotal in longitudinal health research in youth, but potential bias associated with nonparticipation, omitted reports, or dropout threatens its clinical validity. Previous meta-analytic evidence is inconsistent regarding specific determinants of missing data.

OBJECTIVE

This meta-analysis aimed to update and expand upon previous research by examining key participation metrics-acceptance, compliance, and retention-in youth EMA studies. In addition, it sought to identify potential moderators among sample and design characteristics, with the goal of better understanding and mitigating the impact of missing data.

METHODS

We used a bibliographic database search to identify EMA studies involving children and adolescents published from 2001 to November 2023. Eligible studies used mobile-delivered EMA protocols in samples with an average age up to 18 years. We conducted separate meta-analyses for acceptance, compliance, and retention rates, and performed meta-regressions to address sample and design characteristics. Furthermore, we extracted and pooled sample-level effect sizes related to correlates of response compliance. Risk of publication bias was assessed using funnel plots, regression tests, and sensitivity analyses targeting inflated compliance rates.

RESULTS

We identified 285 samples, including 17,441 participants aged 5 to 17.96 years (mean age 14.22, SD 2.24 years; mean percentage of female participants 55.7%). Pooled estimates were 67.27% (k=88, 95% CI 62.39-71.96) for acceptance, 71.97% (k=216, 95% CI 69.83-74.11) for compliance, and 96.57% (k=169, 95% CI 95.42-97.56) for retention. Despite overall poor moderation of participation metrics, acceptance rates decreased as the number of EMA items increased (log-transformed b=-0.115, SE 0.036; 95% CI -0.185 to -0.045; P=.001; R2=19.98), compliance rates declined by 0.8% per year of publication (SE 0.25, 95% CI -1.3 to -0.3; P=.002; R2=4.17), and retention rates dropped with increasing study duration (log-transformed b=-0.061, SE 0.015; 95% CI -0.091 to 0.032; P<.001; R2=10.06). The benefits of monetary incentives on response compliance diminished as the proportion of female participants increased (b=-0.002, SE 0.001; 95% CI -0.003 to -0.001; P=.003; R2=9.47). Within-sample analyses showed a small but significant effect indicating higher compliance in girls compared to boys (k=25; g=0.18; 95% CI 0.06-0.31; P=.003), but no significant age-related effects were found (k=14; z score=0.05; 95% CI -0.01 to 0.16).

CONCLUSIONS

Despite a 5-fold increase in included effect sizes compared to the initial review, the variability in rates of missing data that one can expect based on specific sample and design characteristics remains substantial. The inconsistency in identifying robust moderators highlights the need for greater attention to missing data and its impact on study results. To eradicate any health-related bias in EMA studies, researchers should collectively increase transparent reporting practices, intensify primary methodological research, and involve participants' perspectives on missing data.

A Latent Variable Approach to Affect Variability in Daily Life Accurately Predicts Psychopathology, Especially Depression Symptoms in a Non-Clinical Sample

Background

Ecological momentary assessments (EMA) have contributed to an increase in research correlating affect dynamics to mental health and wellbeing. While many metrics can be calculated to characterize affect dynamics from EMA data, researchers often opt for a 'battle royale' approach whereby only the best individual predictor is kept. The present work addresses the possibility that shared variance across indicators, namely for affect variability, may be better captured using latent models that also could better predict psychopathology.

Methods

A 14-day EMA protocol was used to examine affect dynamics in 109 college-aged participants. Measures of psychopathology were collected on the first and last days. A minimum of 12 observations of the Positive and Negative Affect Schedule reports were needed for each participant. Measures of affect variability, granularity, and co-occurrence were derived.

Results

Depression, anxiety, stress, and neuroticism were positively associated with latent negative affect variability and negatively associated with latent positive affect variability. Granularity and co-occurrence were not significant predictors. Importantly, latent factors were significantly stronger predictors of depression than within-person mean and standard deviations.

Limitations

As with any latent variable study, the factorization is sample-specific and may have limited generalizability. Replication with a clinical sample and larger battery of psychopathology assessments is recommended.

Conclusions

Latent factors coalesce the strengths of several EMA-derived indicators while maintaining statistical and construct validity. Clinical implications are discussed regarding short-burst daily affect assessments to track potential risk for depression onset.

Acupuncture effects on emotional reactivity of youth with self-reported depressive symptoms

Background

Emotional symptomatology is a hallmark of depression. Antidepressant often fail to effectively target emotional blunting, while acupuncture, by contrast, has emerged as a promising alternative. However, the exact electrophysiologic mechanisms remain unclear. This study aimed to investigate how acupuncture influences emotional reactivity in youth with self-reported depressive symptoms.

Methods

A modified oddball paradigm incorporating a negative emotional valence deviant, combined with event-related potential analysis, was used to measure emotional reactivity before and after intervention. Seventy individuals exhibiting depressive symptoms in the previous 2 weeks, were randomly assigned to either a verum or sham acupuncture group. Electroencephalogram data from 59 participants were analyzed following preprocessing and quality assessment. Occipital P1, N170, frontal N1, N2, and parietal P3 components were extracted. The Positive and Negative Affect Schedule (PANAS) was completed after each oddball session. The Massachusetts General Hospital Acupuncture Sensation Scale (MASS) was completed after each intervention session.

Results

The MASS Index was significantly higher in the verum group. However, significant increases in occipital P1, N170, frontal N1, N2, and parietal P3 amplitudes for high-negative, mild-negative, and neutral pictures were observed after the intervention in both the verum and sham groups, with no significant difference between the groups. Additionally, both groups induced PANAS changes, and positive effect changes were significantly correlated with N170 and P1 (in response to high-negative pictures) changes in the sham group.

Conclusion

Acupuncture altered emotional reactivity in youth with depressive symptoms, highlighting its potential role, albeit possibly non-specific, in depression prevention and treatment.

Perceptual sensitivity to labeling stereotyped emotion expressions: Associations with age and subclinical psychopathology symptoms from childhood through early adulthood

This study investigates (a) age-related differences in how the intensity of stereotyped facial expressions influence the emotion label children, adolescents, and adults assign to that face and (b) how this perceptual sensitivity relates to subclinical symptoms of psychopathology. In 2015-2016, 184 participants aged 4-25 years viewed posed stereotypes of angry, fearful, sad, and happy expressions morphed with neutral expressions at 10%-90% intensity. Thin plate regression smoothing splines were used to chart nonlinear associations between age and the perceptual threshold participants needed to assign the emotion label expected based on cultural consensus. Results suggest that sensitivity to labeling stereotypical happy faces as "happy" peaked by age 4. Sensitivity to perceiving stereotypical angry faces as "angry" increased from ages 4 to 7 and then plateaued. In contrast, sensitivity to perceiving stereotypical fearful and sad faces demonstrated protracted development, not reaching a plateau until ages 15 and 16, respectively. Reduction in selecting the "I don't know" response was the primary driver of these age-related changes. Stereotyped fear expressions required the highest intensity to be labeled as such and showed the most marked change in perceptual threshold across development. Interestingly, lower intensity morphs of stereotypical fear faces were frequently labeled "sad." Furthermore, perceiving lower intensity fear morphs was associated with fewer internalizing and externalizing symptoms in participants aged 7-19. This study describes the development of perceptual sensitivity to labeling stereotypical expressions of emotion according to cultural consensus and shows that how people perceive and categorize ambiguous facial expressions is associated with vulnerability to psychopathology.

Examining the association among adolescents' emotional clarity, emotion differentiation, and the regulation of negative and positive affect using a daily diary approach

Emotional clarity and emotion differentiation (ED) are two core aspects of the application of emotional knowledge. During adolescence, novel emotional experiences result in temporary decreases of differentiation and clarity. These temporary difficulties might profoundly impact choices of regulatory strategies. And indeed, prior research has shown that lower emotional clarity and emotion differentiation are each associated with higher use of putatively maladaptive emotion regulation strategies in youth. The two constructs, however, are rarely examined together, and it remains unclear how they are associated in daily life, particularly in children and adolescents. In addition, previous studies have focused on the regulation of negative but not positive affect. To address these gaps, the present study used an intensive longitudinal design in youth. Between June 2021 and March 2022, 172 children and adolescents (M = 12.99 years) completed a 28-day diary (> 3,500 entries in total) reporting daily affect, emotional clarity, and the use of five emotion regulation strategies in response to negative and positive affect (i.e., rumination, dampening, behavioral avoidance, negative and positive suppression). As predicted, on both between- and within-person levels, higher emotional clarity was associated with decreased use of all maladaptive emotion regulation strategies after adjusting for mean affect intensity. Results for emotion differentiation were mostly nonsignificant. Only higher daily positive emotion differentiation was associated with decreased rumination. In sum, this innovative study explores multiple aspects of emotional knowledge usage and regulation during a critical developmental stage and emphasizes the role of emotional clarity in the regulation of negative and positive affect.

Negative emotion differentiation buffers against intergenerational risk for social anxiety in at-risk adolescent girls

Social anxiety disorder (SAD) tends to emerge during adolescence and is more prevalent among those assigned female at birth. Parental social anxiety confers risk for adolescent SAD but less is known regarding protective factors. Research suggests that emotion differentiation (the ability to discriminate between similarly valenced emotions, e.g., fear vs. sadness vs. anger) may be protective, as it is associated with adaptive psychosocial outcomes. However, little work has examined how emotion differentiation influences the development of SAD, particularly during periods of higher risk such as adolescence. In a longitudinal study of adolescent girls at high temperamental risk for SAD (aged 11-14-years; n=114), we tested whether emotion differentiation (derived using negative and positive emotion ratings from 16-day ecological momentary assessments at baseline) moderated the relationship between parental and adolescent social anxiety symptoms across two years. Results revealed significant moderation by negative (but not positive) emotion differentiation (p=.042): Baseline parental social anxiety was positively associated with adolescent social anxiety symptoms at two-year follow-up but only at lower (vs. higher) levels of emotion differentiation, even after controlling for baseline depressive symptoms. Exploratory analyses showed that these effects were unique to avoidance of social situations (p=.014). Findings highlight the protective effects of emotion differentiation and have important clinical implications for understanding and treating SAD.

The Transition from Childhood to Adolescence: Between Health and Vulnerability

Transitioning from childhood into adolescence is an extraordinary time of life, associated with major physical, emotional, cognitive, and social changes and characterized by dynamic development in which interaction with the environment modulates the individual resources responsible for well-being and health. This sensitive period is the time when, in addition to hormonal, metabolic, and neural changes, certain behavioral strategies begin to take shape that will shortly go on to define the emotional, social, and cultural identity of the individual. This narrative review aimed to uncover the crucial processes underlying the transition by identifying processes that are responsible for cognitive, psychosocial, and emotional development, in the absence of disease. For this aim, we highlight (1) the physical, psychological, and social determinants during the transition from childhood to adolescence; (2) the role of health-related variables in resilience or vulnerability mechanisms; and (3) recent school-based strategies to promote health and well-being. Recognizing that health and well-being are the result of the interaction of many biological, psychological, social, cultural, and physical factors will lead to comprehensive health promotion involving all actors joining the growth process, from health professionals and the educational community to parents and community. Furthermore, it is important that psychosocial dimensions are strengthened already during childhood to prevent the onset of frailty and illness in adolescence.

Experience sampling methodology study of anxiety and depression in adolescents with epilepsy: The role of metacognitive beliefs and perseverative thinking

Emotional distress is common in young people with epilepsy (YPwE). According to the Self-Regulatory Executive Function (S-REF) model, maladaptive metacognitive beliefs and perseverative thinking are fundamental in the development and maintenance of emotional distress. As emotional distress and perseverative thinking can highly fluctuate over short intervals in YPwE, it is important to account for this variability when testing the utility of psychological models. Experience sampling methodology (ESM) was therefore used to explore the momentary relationship between metacognitive beliefs, perseverative thinking, and emotional distress in YPwE. Eighteen participants diagnosed with epilepsy (aged 12-17 years) completed the 10-day ESM period. Participants were prompted to complete the ESM assessment five times daily. The ESM assessment assessed participant's momentary levels of metacognitive beliefs, perseverative thinking (i.e., worry and rumination), and emotional distress (i.e., anxiety and depression). A series of multilevel regression analyses indicated that metacognitive beliefs were significantly positively associated with worry, rumination, anxiety and depression. After controlling for worry and rumination, respectively, metacognitive beliefs did not account for additional variance in anxiety or depression. Findings provide preliminary support for the utility of the S-REF model for emotional distress in YPwE. Metacognitive therapy, which is underpinned by the S-REF model, may be an appropriate intervention for emotional distress in YPwE. Future studies should assess the mediational relationship between metacognitive beliefs, perseverative thinking, and emotional distress using time-lagged models.

The Role of Emotion Differentiation in the Association Between Momentary Affect and Tobacco/Nicotine Craving in Young Adults

INTRODUCTION

Tobacco/nicotine use is commonly initiated during adolescence or young adulthood, which increases the likelihood of continued use into adulthood and related adverse health outcomes. Despite interest in cessation, achieving and maintaining abstinence is difficult among this population. Cravings are often a barrier to abstinence, which have been associated with intensity of affect at the moment level. Emotion differentiation involves the ability to distinguish between discrete emotion states, and previous work suggests it may moderate the effect of momentary affect on craving, which has never been explored among young adults who are smoking or vaping nicotine.

AIMS AND METHODS

In a sample of young adults (N = 37, observations = 2020, ages 18-25, 51% female, and 78% white) interested in quitting smoking or vaping, we used real-time, naturalistic data capture via mobile phones to examine the interaction of momentary affect and trait emotion differentiation on nicotine craving. Participants were prompted with four surveys per day for 35 days and asked to make a 48-h quit attempt on day 7.

RESULTS

Multilevel models showed moments of higher-than-average momentary negative affect (NA; b = 0.39, p < .001), and positive affect (PA; b = 0.26, p = .001) were associated with greater levels of craving. NA emotion differentiation significantly moderated the associations between PA and craving (b = -0.63, p = .031) and NA and craving (b = -0.67, p = .003).

CONCLUSIONS

Findings from this exploratory analysis suggest that for young adults engaging in a nicotine quit attempt, greater ability to differentiate NA weakens the momentary association between intense affect and craving.

IMPLICATIONS

Results of this study show that the ability to differentiate between discrete emotional experiences may protect young adults against nicotine craving during moments of intense affective experience. These preliminary findings suggest that emotion differentiation, a modifiable construct, could be an important treatment target for individuals engaged in treatment for nicotine dependence.

Effects of binge drinking and depression on cognitive-control processes during an emotional Go/No-Go task in emerging adults

INTRODUCTION

The goal of the current study was to examine differences in neurocognitive processes across groups marked by binge drinking and depression to identify patterns of cognitive and affective processing impairments.

METHODS

Undergraduate students (N = 104; 64% female) were recruited based on self-reported symptoms of depression and alcohol use. They completed an emotional Go/No-Go task while undergoing EEG. Mean amplitudes for N2 and P3 components were examined with 2 (Depressed/Non-depressed) X 2 (Binge/Non-binge drinkers) X 4 (Happy/Sad/Angry/Calm) X 3 (Left/Middle/Right) X 2 (Go/No-Go) repeated measures ANOVAs.

RESULTS

There were significant Trial Type X Valence X Depression X Binge Drinking interactions for N2 (F(3, 80) = 6.62, p < .01) and P3 (F(3, 80) = 4.65, p < .01) components. There was a significant Valence X Depression X Binge Drinking interaction for response bias (F(3, 65) = 3.11, p < .05).

LIMITATIONS

The source of our sample may be a limitation, as all participants were university students, potentially making the results less generalizable. Further, we cannot be certain that social desirability did not interfere with honest reporting of alcohol use in this population.

CONCLUSIONS

Differences in early inhibitory control were observed across emotions based on trial type among depressed non-binge drinkers, and these differences were attenuated in the presence of binge drinking. Further, the effects of depression on later inhibitory control were specific to non-binge drinkers. Results help to clarify the nature of underlying patterns of neurocognitive and affective risk processes that could be targeted by prevention and intervention programs.

Examining the Role of Emotion Differentiation on Emotion and Cardiovascular Physiological Activity During Acute Stress

Emotion differentiation (ED) - the tendency to experience one's emotions with specificity - is a well-established predictor of adaptive responses to daily life stress. Yet, there is little research testing the role of ED in self-reported and physiological responses to an acute stressor. In the current study, we investigate the effects of negative emotion differentiation (NED) and positive emotion differentiation (PED) on participants' self-reported emotions and cardiac-mediated sympathetic nervous system reactivity (i.e., pre-ejection period) in response to a stressful task. Healthy young adults enrolled in a two-session study. At an initial session, participants completed a modified experience sampling procedure (i.e., the Day Reconstruction Method). At session 2, 195 completed the Trier Social Stress Test while cardiac impedance was acquired throughout. Linear regressions demonstrated that higher NED, but not PED, was associated with experiencing less intense self-reported negative, high arousal emotions (e.g., irritated, panicky) during the stressor (β =  - .15, p < .05) although people with higher NED also exhibited greater sympathetic reactivity (β = .16, p < .05). In exploratory analyses, we tested whether the effect of NED on self-reported stress was mediated by the tendency to make internally focus (or self-focused) attributions about performance on the task but did not find a significant indirect effect (p = .085). These results both complement prior work and provide a more complex picture of the role of NED in adaptive responses to stressful life events, suggesting that people with higher NED may experience their emotions as more manageable regardless of their level of physiological arousal.

Exploring the perception of stress in childhood and early adolescence

Stressful life experiences may jeopardize the healthy development of children. To improve interventions, more knowledge is needed on the perception of stress by children. In adults, stress is regarded as a state of low valence and high arousal. It is unclear whether children perceive stress similarly. In the current study, 35 children of the general population completed three tasks aiming to provide insight into their knowledge of the concept stress. In the first task, participants were asked about their verbal knowledge of the concept stress. In the second task, they rated the valence and arousal of eight emotion-evoking vignettes. In the final task, participants completed an experience sampling survey for at least 1 day, consisting of a stress thermometer and pictorial scales of valence and arousal. Participants' perception of stress was found to be mainly valence focused. Age and sex were found to play a role in the degree of arousal focus. Older participants differentiated more in arousal levels than younger participants, as did girls in comparison with boys. Because the perception of stress depends on developmental and other individual factors, using stress as a single measurement dimension in a survey is not recommended.

Effects of chronic stress on smartphone addiction: A moderated mediation model

Introduction

Based on the compensatory Internet use theory and diathesis-stress model, the present study explores the effects of chronic stress on smartphone addiction (SPA). As intolerance of uncertainty and emotion-related variables are important factors that affect addictive behavior, we explore the mediating role of intolerance of uncertainty and the moderating role of emotion differentiation.

Methods

We conducted a questionnaire survey of 286 participants (13.64% female; M _age = 22.88; SD = 3.77; range = 17-39) on chronic stress, SPA, intolerance of uncertainty, and emotion differentiation. SPSS 28.0 was used to analyze the descriptive statistics and correlations and test the moderated mediation model.

Results

We find that (1) intolerance of uncertainty, SPA, and chronic stress are positively correlated with each other. Positive emotion differentiation is positively correlated with intolerance of uncertainty and negative emotion differentiation. (2) Intolerance of uncertainty plays a mediating role in chronic stress and SPA. (3) Positive emotion differentiation significantly moderates the relationship between chronic stress and SPA. Under the condition of low positive emotion differentiation, chronic stress is more effective in predicting SPA.

Discussion

These findings may contribute to intervention and prevention programs for SPA. Thus, the intervention and prevention of SPA can start from two directions-reduce the intolerance of uncertainty and enhance the ability to experience positive emotion differentiation.

Sad, Sadder, Saddest: Recognition of Sad and Happy Emotional Intensity, Adverse Childhood Experiences and Depressive Symptoms in Preschoolers

Adverse childhood experiences (ACES) have repeatedly been associated with depression. The ability to differentiate emotional intensity is a protective factor for psychopathology and in the context of life stressors, poor negative emotion differentiation (ED) is associated with depressive symptoms. However, little is known about whether the ability to recognize negative emotional intensity, a theorized developmental prerequisite of ED, influences the relationship between ACES and depressive symptoms in early childhood. The current study examined the interactive effects of ACES, the ability to recognize emotional intensity and depressive symptoms in 249 preschoolers enriched for depression. Findings demonstrated that when experiencing ACES, sad (not happy) emotion recognition was associated with elevated depressive symptoms. Specifically, when facing multiple ACEs, preschoolers with poor and moderate ability to recognize sad emotional intensity exhibited elevated depressive symptoms. Findings demonstrate that when experiencing elevated ACES, sad emotion recognition may be a protective factor for depression in early childhood.

Attachment and Depressive Symptoms in Adolescence: The Mediatory Role of Emotion Awareness

Attachment seems to influence depression through emotion regulation. However, no study has yet examined the mediatory role of emotion awareness, a particular subset of emotion regulation abilities, in the relationship between attachment and depressive problems in early and middle adolescence. The aim of this study is to examine the direct and indirect effects of attachment on depressive symptoms in adolescence, considering the mediatory role of emotion awareness dimensions. A sample of adolescents (n = 223) filled up self-report questionnaires on attachment, emotion awareness and depression. Serial mediation models suggest direct effects on depression: negative for secure attachment and positive for anxious/ambivalent attachment. Anxious/ambivalent attachment has a positive indirect effect through lower differentiation of emotions. Both secure and anxious/ambivalent attachment have indirect positive effects on depression through the sequence of bodily unawareness and differentiation of emotions. Differentiating emotions has a central role in mediating the relationship between attachment and depressive symptoms, and the lack of bodily awareness of emotions contributes to such mediation.

There must be a way out: The consensual qualitative analysis of best coping practices during the COVID-19 pandemic

Despite the continuous efforts to understand coping processes, very little is known about the utilization of best coping strategies during the COVID-19 pandemic. In this study, we aimed to analyze the coping strategies of individuals who scored high on an adaptive coping questionnaire in order to understand the most adaptive coping strategies during the COVID-19 pandemic. We used consensual qualitative analysis in a team of four researchers and one auditor. The convenience sample from which we identified the high scorers comprised 1,683 participants (67% women, 32.35% men, and 0.65% did not report their gender) with a mean age of 31.02 years (SD = 11.99) ranging between 18 and 77 years old. Based on their scoring in the COPE Inventory, nine participants were selected from the sample with the highest scores in coping skills in at least two out of its 15 subscales. In-depth repeated interviews with six participants for the main analysis were conducted, and three were added to check the data saturation. The results showed that the most adaptive coping strategies used during the COVID-19 pandemic could be categorized into four main domains: self-compassion, compassion to others, compassion from others, and mutual compassion. The most frequently mentioned and the most elaborated upon by our respondents was the domain of self-compassion. The most interesting finding was the emergence of the fourth type of compassion, labeled mutual compassion, which referred to deliberate attempts to take care of oneself and others while suffering together in order to elevate the suffering for both. This kind of compassion might arise in the situations of collective suffering, such as a catastrophe or a pandemic and might have the additional benefit of bringing people closer to each other in difficult times.

Transactional links between children daily emotions and internalizing symptoms: a six-wave ecological momentary assessment study

BACKGROUND

This study explored the cross-sectional and longitudinal associations between everyday emotion dimensions and internalizing symptoms during the transition to early adolescence. We tested associations between children's intensity and instability of daily negative emotions (NE), positive emotions (PE), and daily NE differentiation (NED) with children's self-reported and their mothers' report of children's internalizing symptoms, across six waves, each wave separated by six months.

METHODS

The sample included 199 ethnically diverse mother [M_age at baseline = 40.1 years (SD = 6.1] and child [M_age at baseline = 10.1 (SD = 0.90), 51% girls] dyads, who participated in six 7-day waves of ecological momentary assessment (EMA). During each wave, children reported on PE (i.e. happy and joyful) and NE (i.e. mad, sad, and stressed) up to eight random times per day through smartphone-based EMA. Children and mothers reported on children's internalizing symptoms at each wave. We used random-intercept cross-lagged panel models (RI-CLPMs) to test within- and between-person effects.

RESULTS

At the within-person level, increased NE and decreased PE intensity, more unstable NE and PE, and decreased NED at any given wave were positively associated with children's self-reported internalizing symptoms but not with mother-reported child symptoms. However, emotion dimensions did not predict child-reported nor mother-reported child symptoms at the next wave. At the between-person level, higher average NE, more unstable PE and NE, and lower NED were positively associated with average child-reported and mother-reported child internalizing symptoms.

CONCLUSIONS

This study suggests that emotional intensity, instability, and differentiation could be conceptualized as manifestations of internalizing symptoms but not as risk factors for its progression, or residual manifestations of it, among typical children.

Negative Emotion Differentiation Attenuates the Within-Person Indirect Effect of Daily Stress on Nightly Sleep Quality Through Calmness

The ability to differentiate between negative emotional states [negative emotion differentiation (NED)] has been conceptualized as a trait that facilitates effective emotion regulation and buffers stress reactivity. In the present research, we investigated the role of NED in within-person processes of daily affect regulation and coping during times of stress (the first COVID-19-related pandemic lockdown in April 2020). Using intensive longitudinal data, we analyzed whether daily stress had an indirect effect on sleep quality through calmness in the evening, and we tested whether NED moderated this within-person indirect effect by buffering the link between daily stress and calmness in the evening. A non-representative community sample (n = 313, 15–82 years old) participated in a 21-day ambulatory assessment with twice-daily surveys. The results of multilevel mediation models showed that higher daily stress was related to within-day change in calmness from morning to evening, resulting in less calmness in the evening within persons. Less calmness in the evening, in turn, was related to poorer nightly sleep quality within persons. As expected, higher NED predicted a less negative within-person link between daily stress and calmness in the evening, thereby attenuating the indirect effect of daily stress on nightly sleep quality through calmness. This effect held when we controlled for mean negative emotions and depression. The results provide support for a diathesis-stress model of NED, and hence, for NED as a protective factor that helps to explain why some individuals remain more resilient during times of stress than others.

Emotion Differentiation and Youth Mental Health: Current Understanding and Open Questions

A growing body of research identifies emotion differentiation-the ability to specifically identify one's emotions-as a key skill for well-being. High emotion differentiation is associated with healthier and more effective regulation of one's emotions, and low emotion differentiation has been documented in several forms of psychopathology. However, the lion's share of this research has focused on adult samples, even though approximately 50% of mental disorders onset before age 18. This review curates what we know about the development of emotion differentiation and its implications for youth mental health. I first review published studies investigating how emotion differentiation develops across childhood and adolescence, as well as studies testing relations between emotion differentiation and mental health in youth samples. Emerging evidence suggests that emotion differentiation actually falls across childhood and adolescence, a counterintuitive pattern that merits further investigation. Additionally, several studies find relations between emotion differentiation and youth mental health, but some instability in results emerged. I then identify open questions that limit our current understanding of emotion differentiation, including (i) lack of clarity as to the valid measurement of emotion differentiation, (ii) potential third variables that could explain relations between emotion differentiation and mental-health (e.g., mean negative affect, IQ, personality, and circularity with outcomes), and (iii) lack of clear mechanistic models regarding the development of emotion differentiation and how it facilitates well-being. I conclude with a discussion of future directions that can address open questions and work toward interventions that treat (or even prevent) psychopathology.

Multiple emotions, multiple selves: compassion focused therapy chairwork

Compassion focused therapy (CFT) is rooted in an evolutionary view of the human mind as formed of a multitude of contrasting, and often conflicting, motivations, emotions and competencies. A core aim of the therapy is to help clients understand the nature of their mind in a way that is de-pathologizing and de-shaming. The approach is also focused on the cultivation of compassion to work with these difficult aspects of mind. CFT includes the ‘multiple-selves’ intervention which involves the differentiation of threat-based emotion and an exploration of their conflict. Compassion is then applied to the client’s affective world to aid regulation and integration. This paper focuses on clients’ experiences of a chairwork version of multiple-selves, wherein clients personify their emotions in separate chairs. Nine participants with depression were interviewed directly following the intervention and the resulting data were analysed using interpretative phenomenological analysis. Three interconnecting themes were identified: appreciating emotional complexity; the role of chairwork process; and compassionate integration. The results highlight the importance of emotional differentiation in understanding internal multiplicity and conflict in depression, and the role of compassion in creating a sense of personal coherence. The embodied and enactive nature of chairwork was found to be of benefit in identifying and separating emotion, and in developing new forms of self-relating. The paper discusses the clinical implications of such findings for the treatment of depression.

High emotion differentiation buffers against internalizing symptoms following exposure to stressful life events in adolescence: An intensive longitudinal study

Exposure to stressful life events is strongly associated with internalizing psychopathology, and identifying factors that reduce vulnerability to stress-related internalizing problems is critical for development of early interventions. Drawing on research from affective science, we tested whether high emotion differentiation-the ability to specifically identify one's feelings-buffers adolescents from developing internalizing symptoms when exposed to stress. Thirty adolescents completed a laboratory measure of emotion differentiation before an intensive year-long longitudinal study in which exposure to stress and internalizing problems were assessed at both the moment-level (n=4,921 experience sampling assessments) and monthly-level (n=355 monthly assessments). High negative and positive emotion differentiation attenuated moment-level coupling between perceived stress and feelings of depression, and high negative emotion differentiation eliminated monthly-level associations between stressful life events and anxiety symptoms. These results suggest that high emotion differentiation buffers adolescents against anxiety and depression in the face of stress, perhaps by facilitating adaptive emotion regulation.

Emotion Naming Impedes Both Cognitive Reappraisal and Mindful Acceptance Strategies of Emotion Regulation

Friends and therapists often encourage people in distress to say how they feel (i.e., name their emotions) with the hope that identifying their emotions will help them cope. Although lay and some psychological theories posit that emotion naming should facilitate subsequent emotion regulation, there is little research directly testing this question. Here, we report on two experimental studies that test how naming the emotions evoked by aversive images impacts subsequent regulation of those emotions. In study 1 (N = 80), participants were randomly assigned into one of four between-subjects conditions in which they either (i) passively observed aversive images, (ii) named the emotions that these images made them feel, (iii) regulated their emotions by reappraising the meaning of images, or (iv) both named and regulated their emotions. Analyses of self-reported negative affect revealed that emotion naming impeded emotion regulation via reappraisal. Participants who named their emotions before reappraising reported feeling worse than those who regulated without naming. Study 2 (N = 60) replicated these findings in a within-participants design, demonstrated that emotion naming also impeded regulation via mindful acceptance, and showed that observed effects were unrelated to a measure of social desirability, thereby mitigating the concern of experimenter demand. Together, these studies show that the impact of emotion naming on emotion regulation opposes common intuitions: instead of facilitating emotion regulation via reappraisal or acceptance, constructing an instance of a specific emotion category by giving it a name may "crystalize" one's affective experience and make it more resistant to modification.

Maternal Depression History Moderates the Association Between Criticism (but not Praise) and Depressive Symptoms in Youth

Children of mothers with past depression are at increased risk for developing the disorder themselves; however, the specific factors that increase their risk are unclear. Aberrant reactivity to social experiences may be one characteristic that increases risk for depression in offspring. This study investigates whether mothers' depression history is associated with increased reactivity to criticism and decreased reactivity to praise in offspring by examining 72 youths (ages 8-15). Every evening for 21 days, youths reported their depressive symptoms and whether they were criticized and/or praised by their mothers, fathers, siblings, and friends, resulting in 1,382 data entries across participants. Mothers reported their own depression history and current depressive symptoms. Maternal depression history moderated offspring's response to criticism. Although all youths reacted to perceived criticism from family members with transient increases of depressive symptoms, only children of mothers with higher (vs. lower) levels of past depression exhibited cumulative, person-level associations between perceived criticism and their own depressive symptoms. Additionally, only children of depressed mothers exhibited increases in depressive symptoms on days in which they were criticized by friends. Perceived parental praise was associated with lower levels of depression in youths regardless of maternal depression. Youth depressive symptoms were more strongly related to their parents' (vs. siblings or friends) criticism and praise, highlighting parents' more central role in youth depression risk. Taken together, our results reveal that maternal depression history is associated with increased reactivity to perceived criticism across relational contexts potentially contributing to youths' risk for developing depression.

Community-Based Participatory Research: Engaging Youth to Provide Perspective on Risk and Protective Factors

BACKGROUND

The Pennsylvania Youth Survey (PAYS) is administered biennially to adolescents; it covers knowledge, attitudes, and behaviors about risk and protective factors.

PURPOSE

This study explored 8th, 10th, and 12th grade students' attitudes and beliefs about current trends regarding drugs, alcohol, and mental health.

METHODS

We asked persons a series of questions in semi-structured focus groups (102 participants) while they were being presented with the PAYS data.

RESULTS

Participants expressed significant insight on root causes of risk behaviors. They recommended a decreased emphasis on grades and class rank, and recommended addressing mental health stigma, educating about vaping and marijuana effects, and obtaining support from families, schools, and communities.

CONCLUSION

Youth expressed interest in being an integral part of the planning and decision-making efforts that impact them. Our results support the Whole School, Community, and Child (WSCC) model.

Negative Emotion Differentiation through a Developmental Lens: Associations with Parental Factors and Age in Adolescence

Negative emotion differentiation (NED) is the ability to precisely discern negatively-valenced emotional states. Low NED has been linked to numerous negative outcomes. However, little is known about the conditions under which individual differences in NED emerge, particularly during adolescence, a potentially important developmental stage. We examined associations between NED (assessed using intraclass correlations between negative emotion [NE] ratings collected via intensive longitudinal methods), parental variables, and age. Adolescents (N=233, M _age=15.90, 53% female) and their parents completed interview measures of depression and self-report questionnaires; adolescents then completed a seven-day ecological momentary assessment. Lower NED was associated with greater parental depression, greater authoritarian parenting style, and lower parental attachment security. Age was negatively and linearly associated with NED. Results held controlling for mean NE and adolescent depression, although authoritarian parenting was non-significant controlling for other developmental variables. Findings suggest healthy parent-child relationships may relate to adolescents' ability to perceive NEs with nuance.
