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

Perceived stress moderates emotion regulation success in real-world contexts: an ecologically-valid multilevel investigation

BACKGROUND

Emotion regulation plays a crucial role in well-being in everyday life. Effective emotion regulation depends upon adaptively matching a given strategy to a given situation. Recent research has begun to explore these interactions in the context of daily reports of perceived stress, affect, and emotion regulation strategy usage. To further understand these differences in strategy efficacy in an ecologically valid context, we examined responses to real world stressors in a young adult sample.

METHODS

We surveyed a range of emotion regulation strategies, including two forms of cognitive reappraisal (i.e., reinterpretation, which involves cognitively reframing one's emotional responses, and psychological distancing, which involves adopting an objective, impartial perspective). Participants reported strategy usage, momentary perceived stress, and affect in response to multiple ecological momentary assessments over a period of 7 days.

RESULTS

Analyses of links between strategy usage and affect revealed that rumination was significantly negatively associated with more positive affect ratings. Further, a significant interaction between momentary perceived stress and reinterpretation usage was observed on affect, such that reinterpretation was more adaptive during situations perceived as less stressful.

CONCLUSION

These results provide further insight into the importance of situational context in determining the effectiveness of particular emotion regulation strategies.

Fluctuations in emotion regulation as a mechanism linking stress and internalizing psychopathology among adolescents: An intensive longitudinal study

Stressful life events (SLEs) are tightly coupled with the emergence of anxiety and depression symptoms among adolescents, but the mechanisms underlying this relationship remain poorly understood. We investigated within-person fluctuations in emotion regulation as a mechanism linking SLEs and internalizing psychopathology in an intensive longitudinal study. We examined how monthly fluctuations in SLEs were related to engagement in three emotion regulation strategies-acceptance, reappraisal, and rumination-and whether these strategies were associated with changes in internalizing symptoms in adolescents followed for one year (N = 30; n = 355 monthly observations). Bayesian hierarchical models revealed that on months when adolescents experienced more SLEs than was typical for them, they also engaged in more rumination, which, in turn, was associated with higher anxiety and depression symptoms and mediated the prospective relationship between SLEs and internalizing symptoms. In contrast, greater use of acceptance and reappraisal selectively moderated the association between stressors and internalizing symptoms, resulting in stronger links between SLEs and symptoms. These results suggest that emotion regulation strategies play different roles in the stress-psychopathology relationship. Understanding how changes in emotion regulation contribute to increases in internalizing symptoms following experiences of stress may provide novel targets for interventions aimed at reducing stress-related psychopathology.

How do "words poorly expressed emotion" affect mental health? The mediating role of affect labelling effect

Previous studies have found that people with high negative emotional granularity(NEG) tend to have better health levels. It is generally believed that this is due to the selection and application of explicit emotion regulation strategies that affect mental health. However, no research has yet examined a more fundamental process, the role of affect labelling, an implicit emotion regulation strategy. This study focuses on the aforementioned issues and uses the experience sampling method to categorise participants into groups with high and low NEG. Using an affect labelling paradigm with ERP(event-related potential) technology, the study measures the effects of affect labelling in participants. Furthermore, it assesses the mental health levels of the participants through questionnaires to explore whether the affect labelling effect serves as a mediator between NEG and mental health. The results show that: (1) The high-NEG group exhibited significantly lower LPP wave amplitudes under affect labelling compared to under non-affect labelling, whereas the low-NEG group did not show significant differences. The results indicate that only the high-NEG group can produce the affect labelling effect. (2) The affect labelling effect mediates the relationship between NEG and mental health, meaning that NEG predicts mental health through the affect labelling effect.

Moderating effect of negative emotion differentiation in chronic stress and fatigue among Chinese employees

Introduction

According to the reactivity hypothesis and the diathesis-stress model, repeated activation of the stress system has a negative effect on health, and this effect may differ because of individual characteristics. Thus, the present study explores the effect of chronic stress on fatigue and investigates its mechanism.

Methods

A questionnaire survey of 288 participants selected from the northwest part of China was conducted (13.89% females; ages ranged from 18 to 34 years, with M ± SD = 23.14 ± 3.79 years) on chronic stress, fatigue, depression, anxiety, and negative emotion differentiation. SPSS 28.0 was used to process descriptive statistics and correlation analysis and the PROCESS macro was used to analyze the moderated chained multi-mediation.

Results

Chronic stress was found to be positively correlated with fatigue, depression, and anxiety; depression and anxiety played a chained multi-mediating role between chronic stress and fatigue, and negative emotion differentiation played a moderating role in the chained multi-mediation model.

Discussion

Compared with depression, anxiety plays a more important role in the influence of chronic stress on fatigue. Therefore, it is necessary to pay more attention to anxiety symptoms and take appropriate intervention measures. Negative emotion differentiation plays a moderating role. Improving negative emotion differentiation through mindfulness and adaptive emotion regulation is an effective way to reduce the influence of chronic stress on fatigue.

A cognitive-computational account of mood swings in adolescence

Teenagers have a reputation for being fickle, in both their choices and their moods. This variability may help adolescents as they begin to independently navigate novel environments. Recently, however, adolescent moodiness has also been linked to psychopathology. Here, we consider adolescents' mood swings from a novel computational perspective, grounded in reinforcement learning (RL). This model proposes that mood is determined by surprises about outcomes in the environment, and how much we learn from these surprises. It additionally suggests that mood biases learning and choice in a bidirectional manner. Integrating independent lines of research, we sketch a cognitive-computational account of how adolescents' mood, learning, and choice dynamics influence each other, with implications for normative and psychopathological development.

Bidirectional associations between sleep problems and suicidal thought/attempt in adolescents: A 3-wave data path analysis

PURPOSE

This longitudinal data analysis examined the bidirectional relationships between sleep problems and suicidal thought (ST)/attempt (SA) in a large sample of Chinese adolescents.

METHODS

A total of 6995 adolescents (mean age = 14.86 years and 51.4% males) participated in a 3-wave longitudinal study of behavior and health in Shandong, China. A self-administered questionnaire and standardized scales were used to assess ST, SA, sleep duration, insomnia, daytime sleepiness, and behavioral/emotional problems in 2015 (T1), 1 year later (T2), and 2 years later (T3). Path analyses were performed without and with adjustment for covariates, including gender, grade level, chronic diseases, cigarette smoking, alcohol use, anxiety/depressive symptoms, paternal education, and family economic status.

RESULTS

The prevalence rates of short sleep (<7 h/night), insomnia symptoms, and daytime sleepiness were 46.9-58.8%, 16.0-19.4%, and 25.1-25.3% at T1, T2, and T3, respectively. The rates of past-year ST and SA were 9.1-12.4% and 1.6-2.4% at T1, T2, and T3, respectively. Path analyses showed that short sleep, insomnia, and daytime sleepiness predicted subsequent ST, and vice versa. Daytime sleepiness and SA predicted each other 1 year later. Sleep problems and ST/SA in the previous year significantly predicted themselves in the follow-up year.

STUDY LIMITATION

All data were based on self-report.

CONCLUSION

Short sleep, insomnia, and daytime sleepiness all had bidirectional relationships with ST. Daytime sleepiness and SA were bidirectionally linked. Our findings suggest that interventions should be taken for both night sleep disturbances and daytime sleepiness to prevent suicide. Adverse sleep outcomes in suicidal adolescents should be assessed, which can in turn increase suicide risk.

Life stress and suicidality mediated by insomnia and depressive symptoms in adolescents: a three-wave longitudinal study

STUDY OBJECTIVES

Little empirical work has investigated the associations between life stress (LS), insomnia, depression, and suicidality in multi-wave longitudinal studies. With three waves of data collection 1-year apart, this longitudinal study with a large sample of adolescents examined the predicting effects of LS on suicidality 1-year later and 2 years later and the mediating roles of insomnia and depression in the LS-suicidality link.

METHODS

A total of 6995 adolescents (mean age = 14.86 years, 51.4% male) participated in a three-wave longitudinal study of behavior and health in Shandong, China. A self-administered structured questionnaire and standardized scales were used to assess suicidality (including suicidal thought [ST], suicide plan [SP], and suicide attempt [SA]), LS, insomnia, and depression in 2015 (T1), 1-year later (T2), and 2 years later (T3). Mediation effects were examined with path models.

RESULTS

The overall prevalence rates of past-year suicidality were 13.4% at T1, 10.0% at T2, and 9.5% at T3, respectively. The prevalence rates of suicidality across T1-T3 significantly increased with elevated levels of baseline LS, insomnia, and depression (p < .001). Path models indicated that the relationship between baseline LS and suicidal ideation (i.e., ST/SP) 2 years later was significantly mediated by both insomnia and depression. Depression was also a significant mediator between LS and SA.

CONCLUSIONS

LS is a significant predictor of suicidality 1-2 years later in adolescents. Depression mediates the association between LS and suicidal ideation and suicide attempt while insomnia appears to be a mediator for suicidal ideation rather than suicide attempt.

Starting a Romantic Relationship, Breakups, and Sleep: A Longitudinal Study of Chinese Adolescents

BACKGROUND

Epidemiological data on the association between romantic experiences and sleep in adolescents are limited. This study examined the associations of starting a romantic relationship (SRR) and romantic breakups with insomnia symptoms and sleep duration in adolescents.

METHODS

A total of 7,072 Chinese adolescents were surveyed in November-December 2015 and 1 year later. A self-administered questionnaire was used to assess SRR, romantic breakups, sleep duration, insomnia symptoms, depressive symptoms, substance use, and demographics.

RESULTS

The mean age of the sample was 14.58 (SD = 1.46) years and half were female. SRR only, breakups only, and both (SRR + breakups) in the past year were reported by 7.0%, 8.4%, and 15.4% of the sample, respectively. At the baseline and 1-year follow-up, 15.2% and 14.7% of the sample had insomnia symptoms and 47.7% and 42.1% reported short sleep duration (<7 h/night), respectively. After adjusting for depressive symptoms, substance use, and demographics, SRR and breakups were significantly associated with 35-45% increased odds of insomnia symptoms at baseline. SRR + breakups were significantly associated with short sleep duration (OR = 1.28, 95%CI = 1.05-1.56). SRR (OR = 1.61, 95%CI = 1.16-2.23) and breakups (OR = 1.43, 95%CI = 1.04-1.96) were significantly associated with increased odds of incident insomnia symptoms at 1-year follow-up. These associations were stronger in younger adolescents (<15 years) than in older adolescents (≥15 years), especially in girls.

CONCLUSIONS

The findings suggest that SRR and breakups are associated with insomnia symptoms and short sleep duration, underscoring the importance of romantic relationships education and management of romantic stress for healthy sleep especially in early adolescent girls.

Emotion differentiation among individuals in a randomized clinical trial for alcohol use disorder: Within- and between-person associations with affect, craving, and alcohol use in daily life

Emotion differentiation refers to cognitively distinguishing among discrete, same-valenced emotions. Negative emotion differentiation (NED) is a transdiagnostic indicator of emotional functioning. The role of positive emotion differentiation (PED) in clinical disorders, including alcohol use disorder (AUD), is less understood. Further, despite consensus that emotions are highly variable, little is known about within-person fluctuations in NED/PED. The current study leveraged 84 consecutive daily smartphone surveys from participants (N = 181) in a clinical trial of cognitive behavioral therapy for AUD to investigate whether between-person differences in overall NED/PED, or within-person variability in daily NED/PED, were associated with affect intensity, craving, drinking, and heavy drinking in daily life. Subsequent analyses explored whether associations were moderated by baseline alexithymia. At the between-persons level, greater average PED, but not NED, was associated with lower heavy drinking odds. At the within-persons level, higher-than-usual PED was associated with lower negative affect and odds of any drinking. Individuals with baseline alexithymia had stronger negative within-person associations between daily NED and both any and heavy drinking. PED is a skill linked to less alcohol use between- and within-persons irrespective of baseline alexithymia, whereas greater daily NED appears especially important for reduced alcohol use among individuals with co-morbid AUD and alexithymia.

A precision neuroscience approach to estimating reliability of neural responses during emotion processing: Implications for task-fMRI

Recent work demonstrating low test-retest reliability of neural activation during fMRI tasks raises questions about the utility of task-based fMRI for the study of individual variation in brain function. Two possible sources of the instability in task-based BOLD signal over time are noise or measurement error in the instrument, and meaningful variation across time within-individuals in the construct itself-brain activation elicited during fMRI tasks. Examining the contribution of these two sources of test-retest unreliability in task-evoked brain activity has far-reaching implications for cognitive neuroscience. If test-retest reliability largely reflects measurement error, it suggests that task-based fMRI has little utility in the study of either inter- or intra-individual differences. On the other hand, if task-evoked BOLD signal varies meaningfully over time, it would suggest that this tool may yet be well suited to studying intraindividual variation. We parse these sources of variance in BOLD signal in response to emotional cues over time and within-individuals in a longitudinal sample with 10 monthly fMRI scans. Test-retest reliability was low, reflecting a lack of stability in between-person differences across scans. In contrast, within-person, within-session internal consistency of the BOLD signal was higher, and within-person fluctuations across sessions explained almost half the variance in voxel-level neural responses. Additionally, monthly fluctuations in neural response to emotional cues were associated with intraindividual variation in mood, sleep, and exposure to stressors. Rather than reflecting trait-like differences across people, neural responses to emotional cues may be more reflective of intraindividual variation over time. These patterns suggest that task-based fMRI may be able to contribute to the study of individual variation in brain function if more attention is given to within-individual variation approaches, psychometrics-beginning with improving reliability beyond the modest estimates observed here, and the validity of task fMRI beyond the suggestive associations reported here.

The relationship of negative life events, trait-anxiety and depression among Chinese university students: A moderated effect of self-esteem

BACKGROUND

Negative life events are major triggers for depression. How individual physical qualities and psychological resources affect the relationship between negative life events and depression in college students remains to be studied. Therefore, we constructed a structural equation model to explore the mediating effect of trait anxiety and the moderating effect of self-esteem in the relationship between negative life events and depression among college students.

METHODS

A total of 6224 Chinese college students (aged 16-25) in Jiangxi Province in the central area of China completed the online survey. A moderated mediation model was tested to verify the hypothesis.

RESULTS

The mediation analysis showed a significant indirect effect of negative life events on depression through trait-anxiety. Mediation was moderated by self-esteem, which significantly interacted with negative life events to reduce their effect on both anxiety and depression.

LIMITATIONS

All measures were self-reported. The cross-sectional design only provides evidence of correlation.

CONCLUSIONS

The results in this study revealed that self-esteem as a component of psychological defense mechanism to reduce the harm of environmental threats to individuals. Low self-esteem college students are more likely to have adverse effects when experiencing low-level life events. University mental health education reduces the effects of negative life events on trait anxiety and depression of college students by raising their self-esteem levels.

The Promise of Affective Language for Identifying and Intervening on Psychopathology

We are in dire need of innovative tools for reducing the global burden of psychopathology. Emerging evidence suggests that analyzing language (i.e., the words people use) can grant insight into an individual's emotional experiences, their ability to regulate their emotions, and even their current experiences of psychopathology. As such, linguistic analyses of people's everyday word use may be a diagnostic marker of emotional well-being, and manipulating the words people use could foster adaptive emotion regulation and mental health. Given the ubiquity of language in everyday life, such language-based tools for measuring and intervening in emotion and mental health can advance how we identify and treat mental illnesses at a large scale. In this paper, I outline the promise of this approach and identify key problems we must solve if we are to make it a reality. In particular, I summarize evidence connecting language, emotion, and mental health for three key constructs: sentiment (i.e., the valence of one's language), linguistic distancing (i.e., using language to separate oneself from distressing stimuli), and emotion differentiation (i.e., using words to specifically identify one's emotions). I also identify open questions in need of attention for each of these constructs and this area of research as a whole. Overall, I believe the future is bright for the application of psycholinguistic approaches to mental health detection and intervention.

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.

The Moral Injury Experience Wheel: An Instrument for Identifying Moral Emotions and Conceptualizing the Mechanisms of Moral Injury

This paper introduces an infographic tool called The Moral Injury Experience Wheel, designed to help users accurately label moral emotions and conceptualize the mechanisms of moral injury (MI). Feeling wheels have been used by therapists and clinical chaplains to increase emotional literacy since the 1980s. The literature on the skill of emotion differentiation shows a causal relationship between identifying emotions with specificity and emotional and behavioral regulation. Emerging research in moral psychology indicates that differentiating moral emotions with precision is related to similar regulatory effects. Based on this evidence, it is proposed that increasing moral emotional awareness through use of an instrument that visually depicts moral emotions and their causal links to MI will enhance appraisal and flexible thinking skills recognized to reduce the persistent dissonance and maladaptive coping related to MI. Design of the wheel is empirically grounded in MI definitional and scale studies. Iterative evaluative feedback from Veterans with features of MI offers initial qualitative evidence of validity. Two case studies will show utility of the wheel in clinical settings and present preliminary evidence of efficacy.

Managing fear and anxiety in development: A framework for understanding the neurodevelopment of emotion regulation capacity and tendency

How we manage emotional responses to environmental threats is central to mental health, as difficulties regulating threat-related distress can blossom into symptoms of anxiety disorders. Given that anxiety disorders emerge early in the lifespan, it is crucial we understand the multi-level processes that support effective regulation of distress. Scholars have given increased attention to behavioral and neural development of emotion regulation abilities, particularly cognitive reappraisal capacity (i.e., how strongly one can down-regulate negative affect by reinterpreting a situation to change one's emotions). However, this work has not been well integrated with research on regulatory tendency (i.e., how often one spontaneously regulates emotion in daily life). Here, we review research on the development of both emotion regulation capacity and tendency. We then propose a framework for testing hypotheses and eventually constructing a neurodevelopmental model of both dimensions of emotion regulation. Clarifying how the brain supports both effective and frequent regulation of threat-related distress across development is crucial to identifying multi-level signs of dysregulation and developing interventions that support youth mental health.

Life stress, insomnia, and anxiety/depressive symptoms in adolescents: A three-wave longitudinal study

PURPOSE

Life stress has negative impacts on sleep and mental health. Little empirical work has investigated the associations between life stress, insomnia, and anxiety/depressive symptoms (ADS) in multi-wave longitudinal studies. This longitudinal study examined these associations in a large sample of adolescents.

METHODS

A total of 6995 adolescents (mean age = 14.86 years, 51.4 % male) participated in a 3-wave longitudinal study of behavior and health in Shandong, China. Standardized rating scales were used to assess life stress, insomnia, and ADS in 2015 (T1), 1 year later (T2), and 2 years later (T3). Three-wave longitudinal panel models were conducted to examine the prospective relationships between life stress, insomnia, and ADS.

RESULTS

The prevalence and persistence rates of insomnia and ADS across T1-T3 significantly increased with elevated life stress score (p < .001). Cross-lagged panel analysis showed that life stress, insomnia, and ADS at a later time point were significantly predicted by the same variable at earlier time points (all p < .01). Life stress, insomnia, and ADS significantly predicted each other bidirectionally over time (all p < .01). The relationship between life stress and ADS was partially mediated by insomnia. The relationship between life stress and insomnia was partially mediated by ADS.

STUDY LIMITATION

Life stress, insomnia, and ADS were all self-reports.

CONCLUSIONS

Life stress, insomnia, and ADS are prospectively bidirectionally related to one another. Insomnia was a mediator of life stress and subsequent ADS and vice versa. These findings underscore the importance of sleep and mental health assessment and intervention in adolescents following life stress.

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.

Advances in stress and depression research

PURPOSE OF REVIEW

Stress plays a central role in the onset and course of depression. However, only a subset of people who encounter stressful life events go on to experience a depressive episode. The current review highlights recent advances in understanding when, why, and for whom the stress-depression link occurs, and we identify avenues for future research.

RECENT FINDINGS

In the last 18 months, researchers have taken a more nuanced perspective on the biopsychosocial mechanisms critical to the stress-depression link. For example, examination of specific facets of emotion regulation, including emotion regulation flexibility and interpersonal emotion regulation, has been critical to understanding its role in depression. Similarly, refined investigations of social support allowed researchers to identify distinct - and occasionally opposite - outcomes depending on the context or manner in which the support was provided. Researchers also documented that the stress-depression link was enhanced by dysregulation of several stress-sensitive biological systems, such as the immune system, microbiome, endocrine system, and neuroanatomical substrates.

SUMMARY

Recent studies highlight the importance of adopting a nuanced understanding of mechanisms and moderators that explain the stress-depression link. We also encourage continued engagement in collaborative, open science that uses multiple methods to study the full breadth of human diversity.

The Association of Daily Stressors and Daily Emotions to Daily Optimism

Abstract. Daily life events often trigger and co-occur with various emotional reactions, which activate self-regulatory processes. One possible outcome of self-regulatory processes is optimism. Limited research has examined optimism in daily life and potential daily predictors, including stressors, negative emotions, and positive emotions. Emotion differentiation – the ability to identify and label discrete emotional states – has the potential to change the association between daily predictors and optimism. The current study contextualized optimism in the emotion-laden daily life and examined the association of daily stressors and daily negative and positive emotional states to daily optimism and the role of negative and positive emotion regulation on these relationships. The current study adopted a daily diary design and collected self-reported daily responses from a sample of 248 college students over a 7-day study period. The results included concurrent and lagged effects and showed that daily negative affect and positive affect predicted both concurrent daily optimism and the next day’s optimism. Greater negative emotion differentiation predicted higher daily optimism. A better ability to differentiate positive emotions predicted a stronger relation between positive affect and daily optimism. The findings underscored the importance of daily affect and emotion differentiation being important markers for optimism interventions and daily practices.

Exploring the digital footprint of depression: a PRISMA systematic literature review of the empirical evidence

BACKGROUND

This PRISMA systematic literature review examined the use of digital data collection methods (including ecological momentary assessment [EMA], experience sampling method [ESM], digital biomarkers, passive sensing, mobile sensing, ambulatory assessment, and time-series analysis), emphasizing on digital phenotyping (DP) to study depression. DP is defined as the use of digital data to profile health information objectively.

AIMS

Four distinct yet interrelated goals underpin this study: (a) to identify empirical research examining the use of DP to study depression; (b) to describe the different methods and technology employed; (c) to integrate the evidence regarding the efficacy of digital data in the examination, diagnosis, and monitoring of depression and (d) to clarify DP definitions and digital mental health records terminology.

RESULTS

Overall, 118 studies were assessed as eligible. Considering the terms employed, "EMA", "ESM", and "DP" were the most predominant. A variety of DP data sources were reported, including voice, language, keyboard typing kinematics, mobile phone calls and texts, geocoded activity, actigraphy sensor-related recordings (i.e., steps, sleep, circadian rhythm), and self-reported apps' information. Reviewed studies employed subjectively and objectively recorded digital data in combination with interviews and psychometric scales.

CONCLUSIONS

Findings suggest links between a person's digital records and depression. Future research recommendations include (a) deriving consensus regarding the DP definition and (b) expanding the literature to consider a person's broader contextual and developmental circumstances in relation to their digital data/records.

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.

Negative Emotion Differentiation Predicts Psychotherapy Outcome: Preliminary Findings

Emotion differentiation (ED), the extent to which same-valenced emotions are experienced as distinct, is considered a valuable ability in various contexts owing to the essential affect-related information it provides. This information can help individuals understand and regulate their emotional and motivational states. In this study, we sought to examine the extent to which ED can be beneficial in psychotherapy context and specifically for predicting treatment response. Thirty-two prospective patients with mood and anxiety disorders completed four daily assessments of negative and positive emotions for 30 days before receiving cognitive-behavioral treatment. Depression, stress, and anxiety symptoms severity were assessed pre- and post-treatment using self-reports and clinical interviews. We conducted a series of hierarchical regression models in which symptoms change scores were predicted by ED while adjusting for the mean and variability. We found that negative ED was associated with greater self-reported treatment response (except for anxiety) when negative emotional variability (EV) was included in the models. Probing negative ED and EV's interactive effects suggested that negative ED was associated with greater treatment response (except for anxiety) for individuals with lower EV levels. Results were obtained while controlling for mean negative affect. Our findings suggest that negative ED can benefit psychotherapy patients whose negative emotions are relatively less variable. We discuss the meaning of suppression and interactive effects between affect dynamics and consider possible clinical implications.
