The relationship between personality traits and happiness: the mediating role of emotional regulation

BackgroundUnderstanding the factors contributing to happiness in the nursing profession is essential, particularly considering the high levels of stress associated with the job. This study aimed to explore the role of emotion regulation in mediating the relationship between personality traits and nurses’ happiness.ObjectiveThis study aimed to explore the relationship between personality traits and happiness by examining the mediating role of emotion regulation.MethodsA cross-sectional study was conducted with 324 Jordanian and 408 Saudi nurses. Data, including the Big Five personality traits, happiness levels, and measures of emotional regulation, were collected through an online survey. The model’s fit and explanatory capability were verified by Structural Equation Modeling (SEM) using SmartPLS 3.ResultsIn the structural model, agreeableness had a significant effect on happiness, influencing both reappraisal and suppression. Extraversion strongly influences happiness, positively affects reappraisal, and negatively affects suppression. Neuroticism hampers happiness and reappraisal, and has a detrimental effect on suppression. Openness had a positive effect on suppression, whereas consciousness positively affected happiness. Mediation analysis revealed direct effects on happiness, with varying indirect contributions from emotional regulation. Multiple-group analysis revealed no significant differences between Jordan and Saudi Arabia in the association between personality traits and happiness.ConclusionThe findings emphasize the nuanced effects of agreeableness, extraversion, neuroticism, consciousness, and openness on happiness, mediated by emotional regulation. Implementing specific interventions to improve emotional regulation can increase nurses’ happiness regardless of their personality traits. The lack of significant differences between Jordanian and Saudi nurses implies that these relationships are consistent across cultures, offering valuable information for cross-cultural healthcare interventions.

Believing in conspiracy theories: The role of emotional granularity and maladaptive emotion regulation strategies

AbstractThe COVID‐19 pandemic has accelerated the spread of conspiracy theories. Previous research has found that individuals who struggle with emotion regulation are more prone to believing in conspiracy theories. Emotional granularity, or the ability to differentiate between nuanced emotional states, is a key component of effective emotion regulation, yet its relationship with conspiracy beliefs has not been explored thoroughly. Thus, we conducted an experience‐sampling study (165 participants, mean age = 26.32 years) including measures of emotion regulation and differentiation. The findings revealed that individuals who endorse conspiracy theories engage in repetitive thinking about the causes and consequences of events and exhibit a reduced ability to distinguish between negative emotions. This effect, however, was observed only in the performance‐based measure of emotion differentiation, not in the self‐report measures. This suggests that enhancing emotional granularity may help individuals in regulating their emotions more effectively, thereby reducing their vulnerability to adopt conspiracy beliefs.

Web-Based Emotion Regulation Training for Sexual Health: Randomized Controlled Trial.

Effective emotional regulation (ER) skills are important for sexual function, as they impact emotional awareness and expression during sexual activity, and therefore, satisfaction and distress. Emotion regulation interventions may offer a promising approach to improve sexual health. Web-based emotion regulation may be a therapeutic strategy for men and women with sexual health concerns. Nevertheless, there is a scarcity of intervention trials investigating its effects in this context, much less using the internet. This study aims to investigate the effects of a web-based emotion regulation training program for sexual function in both men and women. The participants were recruited based on their self-reported sexual problems, which for men was defined by a score of <25 on the International Index Erectile Function (IIEF) and for women by a score of <26.55 on the Female Sexual Function Index (FSFI). The final sample included 60 participants who were randomized to either a web-based emotion regulation training for sexual function or to a waitlist control group. The treatment consisted of an 8-week web-based emotion regulation training for sexual function. The participants were assessed at baseline, post intervention, and the 3-month follow-up. Of the 60 participants included, only 6 completed all 3 assessment points (n=5, 20% in the treatment group and n=1, 5% in the waitlist control group) after receiving the intervention. At follow-up, there were no significant differences between groups in any measure. Among the intervention completers, large-to-moderate within-group effect sizes were observed between the assessment points on measures of emotion regulation, depression, lubrication, orgasm, thoughts of sexual failure, and abuse during sexual activity. The adherence rate was very low, limiting the generalizability of the findings. Participants who completed the intervention showed improvements in both sexual function domains and emotion regulation. Nonetheless, due to a high dropout rate, this trial failed to collect sufficient data to allow for any conclusions to be drawn on treatment effects.

The Emotion Beliefs Questionnaire: Psychometric properties, norms, and links to affective outcomes

BackgroundThe Emotion Beliefs Questionnaire was recently developed to measure beliefs about the controllability and usefulness of negative and positive emotions. These are beliefs that have been theorised to be influential for emotion regulation and psychological outcomes. However, to date there are few studies utilising large, representative samples to examine the EBQ's psychometric properties and affective correlates. Our aim was to fill this gap by examining the EBQ's psychometric properties and exploring associations between emotion beliefs, emotion regulation, and affective disorder symptoms. MethodsA sample of 1175 adults recruited from the general population in the United States completed measures of emotion beliefs, emotion regulation, and affective disorder symptoms. ResultsConfirmatory factor analyses supported the EBQ's intended subscale structure, where controllability and usefulness beliefs were separated by valence. This structure was invariant across gender, age, and education categories. The EBQ correlated in expected ways with other measures, demonstrating good validity, and had good to excellent levels of internal consistency reliability. LimitationsThis study used a non-clinical sample that was predominantly White. Future work should utilise clinical and cross-cultural samples to maximise generalisability of findings. ConclusionsOur findings indicate that the EBQ is a psychometrically sound tool for measuring the multidimensional emotion belief construct. The EBQ may have clinical utility in the conceptualisation, assessment, and treatment of maladaptive emotion beliefs. Furthermore, our results highlight the importance of considering the potential influence of maladaptive emotion beliefs in emotion dysregulation and affective disorder symptoms.

Unique and interactive effects of emotion regulation difficulties and perceived stress on COVID-19 traumatic stress, anxiety, and safety behavior use: A four-year prospective study

Given that emotion regulation difficulties confer risk for poor responses to stress, they may predict who is at risk for adverse psychological reactions to major, chronic stressors such as the COVID-19 pandemic. Specific adverse reactions to the pandemic may include more severe traumatic stress, anxiety, and excessive safety behavior use (i.e., hand washing). While emotion regulation difficulties may be a diathesis for adverse reactions to chronic stressors, the context(s) by which they may confer elevated risk is unclear. Accordingly, the present longitudinal study examined the interaction between pre-pandemic emotion regulation difficulties and early pandemic perceived stress in predicting subsequent COVID-related traumatic stress, anxiety, and safety behavior use over 32 weeks of the pandemic. Community adults (N = 145) who completed a measure of emotion regulation in 2016 as part of a larger study were recontacted at the start of the pandemic (March 2020) and assessed every two weeks for 32 weeks. Consistent with a diathesis-stress model, the interaction between difficulties in emotion regulation and perceived stress was significant in predicting COVID-19 anxiety (p = 0.003, d = 0.52) such that at high, but not low, levels of perceived stress, difficulties in emotion regulation in 2016 significantly predicted higher COVID-19 anxiety in 2020. The interaction between difficulties in emotion regulation in 2016 and perceived stress early in 2020 approached significance in predicting COVID-19 traumatic stress (p = 0.073, d = 0.31) and safety behavior use (p = 0.069, d = 0.31). These findings highlight that current perceived stress is an important context that potentiates the effects of preexisting emotion regulation difficulties on the emergence of anxiety-related symptoms during COVID-19, which has important implications for diathesis-stress models of adverse reactions to chronic stressors.

On the Trait Like Nature of Emotion Regulation Dynamics: Limited Evidence

Measuring the variable and flexible use of emotion regulation (ER) has been increasingly viewed as a more nuanced approach to understanding ER than only assessing mean-level strategy use. However, it is unclear to what extent ER variability and flexibility are trait-like individual differences that show longitudinal consistency and validity across time. In the current study, we use data from an experience sampling study that uses a burst design, wherein the same participants were tested twice across an interval of one year (NW1 = 396, NW2 = 175). We test the extent to which ER tendency, variability, flexibility, and responsivity are stable across time and show consistent relationships with outcome measures. Tendency and, to some extent, responsivity showed consistency across time; variability and flexibility did not. Further, the associations with outcomes were inconsistent across time for tendency and few consistent patterns of associations emerged for variability, flexibility, or responsivity. These findings suggest that these dynamic measures of emotion regulation may not be best conceptualized as stable within-person traits.

The role of excitement and enjoyment through subjective evaluation of horror film scenes

The popularity of the horror genre is constantly increasing and still has not reached its peak. As a recreational activity, people watch horror movies in pursuit of excitement and enjoyment. However, we still do not know what traits make people seek out this type of increase in arousal (excitement) and why they find it desirable (enjoyment). Consequently, in this study, we sought to identify observer-related factors that allows consumption of horror content as a recreational activity. Participants (N = 558) answered questions about movie-watching habits, completed measures of cognitive emotion regulation, sensation seeking, paranormal beliefs, morbid curiosity, disgust sensitivity, and rated short scenes from horror movies on dimensions of excitement, enjoyment, disgust, fearfulness, and realness. Our findings suggest that the predictors of excitement and enjoyment are slightly different. Perceived disgust negatively affected enjoyment but did not influence to excitement. Further, both excitement and enjoyment were positively predicted by fearfulness and realness ratings of the scenes, and morbid curiosity. Paranormal beliefs, sensation seeking, disgust sensitivity, anxiety, and emotion regulation strategies were not associated with excitement and enjoyment. Future studies should make a distinction between excitement and enjoyment as they are equally important factors with slightly different backgrounds in recreational fear.

Positive psychological traits predict future sleep quality and quantity: exploring emotion regulation as a common mediator

Objective Mindfulness, self-compassion, gratitude, and optimism have each been associated with better sleep quality and quantity; however, their collective and relative contributions to future sleep outcomes remain unexplored. The current study therefore investigated whether baseline levels of these positive psychological traits could predict subsequent sleep quality and quantity. In addition, emotion regulation was examined as a potential common mediator of the relationships between each of the positive traits and sleep. Methods and Measures A prospective, correlational design was employed. Student participants (N = 220) completed self-report measures of mindfulness, self-compassion, gratitude, optimism, emotion regulation and sleep quality and quantity at three separate time-points, each approximately 12 wk apart. Results Hierarchical regression analyses indicated that, collectively, the positive traits at baseline predicted better sleep quality and quantity 12 wk and 24 wk later. Optimism emerged as a unique predictor of sleep at each time-point, with higher levels of optimism predicting better sleep. Maladaptive emotion regulation mediated the relationships between optimism and sleep and self-compassion and sleep. Conclusion Findings are consistent with the idea that positive psychological traits might help to facilitate good sleep quality and quantity and indicate that reductions in maladaptive emotion regulation may underpin associations between some positive traits and sleep.

Validation of the short version of Cognitive Emotion Regulation Questionnaire for adolescents in Norway.

The Cognitive Emotion Regulation Questionnaire (CERQ) is among the most popular and widely used measures of emotion regulation across age groups. This study aimed to validate the CERQ short version (CERQ-short) for use on adolescents in the Norwegian population. A sample of 3461 adolescents (47.3% girls) aged 12-16 years was recruited through the UEVO population-based study of child maltreatment in Norway. Factor structure, reliability, measurement invariance and criterion validity were investigated. Confirmatory factor analysis supported the original nine-factor model including 18 items; however, not a two-factor structure nor a higher order two-factor solution. Internal consistency was adequate for all subscales, with alpha levels ranging from .73 to .84 between subscales across genders. Relationships with internalizing problems measured with the 10-item Hopkins Symptom Checklist and health-related quality of life according to KIDSCREEN-10 supported the criterion-related validity of the Norwegian CERQ-short. Results suggest that the CERQ-short can be used to measure cognitive emotion regulation strategies in the Norwegian adolescent population. The validation of the CERQ-short in Norway could significantly improve mental health care by facilitating better diagnosis, treatment planning, and evaluation, as well as informing public health policy and cross-cultural research.

Affect and mental health across the lifespan during a year of the COVID-19 pandemic: The role of emotion regulation strategies and mental flexibility.

During the COVID-19 pandemic, there has been a rise in common mental health problems compared to prepandemic levels, especially in young people. Understanding the factors that place young people at risk is critical to guide the response to increased mental health problems. Here we examine whether age-related differences in mental flexibility and frequency of use of emotion regulation strategies partially account for the poorer affect and increased mental health problems reported by younger people during the pandemic. Participants (N = 2,367; 11-100 years) from Australia, the UK, and US were surveyed thrice at 3-month intervals between May 2020 and April 2021. Participants completed measures of emotion regulation, mental flexibility, affect, and mental health. Younger age was associated with less positive (b = 0.008, p < .001) and more negative (b = -0.015, p < .001) affect across the first year of the pandemic. Maladaptive emotion regulation partially accounted for age-related variance in negative affect (β = -0.013, p = .020), whereby younger age was associated with more frequent use of maladaptive emotion regulation strategies, which, in turn, was associated with more negative affect at our third assessment point. More frequent use of adaptive emotion regulation strategies, and in turn, changes in negative affect from our first to our third assessment, partially accounted for age-related variance in mental health problems (β = 0.007, p = .023). Our findings add to the growing literature demonstrating the vulnerability of younger people during the COVID-19 pandemic and suggest that emotion regulation may be a promising target for intervention.

Neural correlates of automatic emotion regulation and their association with suicidal ideation in adolescents during the first 90-days of residential care

Background: Suicide is the second leading cause of death for adolescents in the United States. However, relatively little is known about the forms of atypical neuro-cognitive function that are correlates of suicidal ideation (SI). One form of cognitive/affective function that, when dysfunctional, is associated with SI is emotion regulation. However, very little work has investigated the neural correlates of emotion dysregulation in adolescents with SI. Methods: Participants (N = 111 aged 12-18, 32 females, 31 [27.9%] reporting SI) were recruited shortly after their arrival at a residential care facility where they had been referred for behavioral and mental health problems. Daily reports of SI were collected during the participants’ first 90-days in residential care. Participants were presented with a task-fMRI measure of emotion regulation – the Affective Number Stroop task shortly after recruitment. Participants were divided into two groups matched for age, sex and IQ based on whether they demonstrated SI. Results: Participants who demonstrated SI showed increased recruitment of regions including dorsomedial prefrontal cortex/supplemental motor area and parietal cortex during task (congruent and incongruent) relative to view trials in the context of emotional relative to neutral distracters. Conclusions: Participants with SI showed increased recruitment of regions implicated in executive control during the performance of a task indexing automatic emotion regulation. Such data might suggest a relative inefficiency in the recruitment of these regions in individuals with SI.

Does early adversity predict executive functioning difficulties among undergraduates? Dissociations among self-report, performance, and EEG measures.

The present research aimed to determine whether self-reports of early adversity predicted individual differences in self-reported and laboratory-measured executive functioning in college-aged samples. Two studies with young adult samples (n = 231 and n = 61) measured endorsement of adverse childhood experiences (ACEs), self-reported executive functioning difficulties on the Behavior Rating Inventory of Executive Function (BRIEF), and self-report measures of depression and emotion regulation. The second sample also completed laboratory performance tasks of working memory, inhibitory control, and selective attention while electroencephalogram (EEG) was recorded. In both samples, greater self-reported ACEs predicted greater reports of executive functioning difficulties on the BRIEF (rs = 0.378 and 0.322), relationships of medium effect size that remained significant when controlling for depression and emotion regulation variables. In the second sample, despite robust EEG/event-related potential (ERP) task findings in the group as a whole, neither lab task performance nor EEG/ERP measures were reliably correlated with individual differences in ACEs. We consider multiple alternative explanations for why early adversity predicted self-reported executive functioning difficulties but not lab task performance or neural measures in the same sample. These findings may reflect a propensity for negative self-evaluation among those with early adverse experiences, leading to inflated estimates of their own executive function problems. Alternatively, the findings may indicate that the lab tasks are insufficient in tapping aspects of executive functions that are relevant outside the lab context.

Impact of Psychological Stress on Emotion Regulation Strategies during COVID-19 in Young Adults with Self-Reported Social Anxiety

Background: This study sought to evaluate the relations among expressive suppression (ES), cognitive reappraisal (CR), and stress during COVID-19 in young adults with self-reported social anxiety. We hypothesized that social anxiety would positively relate to ES but negatively relate to CR. Furthermore, we predicted that stress severity would moderate the relation between social anxiety and emotion regulation, where higher reports of stress and social anxiety would predict greater ES and lower CR. Methods: Participants were young adults (N = 84; 18-24 years old) who completed self-report measures of social anxiety, stress, and emotion regulation amid COVID-19. Zero-order correlations assessed relations among these variables. Moderation analyses assessed stress as a moderator of the relation between social anxiety and emotion regulation. Results: Results indicated that social anxiety was significantly correlated with ES but not CR. The relation between social anxiety and ES was moderated by stress severity, such that as stress increased, individuals with higher social anxiety engaged in less ES. Stress did not moderate the relation between social anxiety and CR. Conclusions: The current study suggests that self-reported social anxiety is positively associated with ES (but not CR) during COVID-19; however, individuals with high social anxiety and perceived stress engaged in less ES.

Adapting the Emotion Regulation Scale for Athletes for Use with Referees and Examining Its Psychometric Properties

This study has aimed to adapt the Emotion Regulation Scale for Athletes (ERSA) developed by Tingaz and Altun (2021) for referees. Materials and Methods: Using the convenience sampling method, 355 class referees actively serving within the basketball and handball federations in 2021-2022 were included in the study. Of the referee group, 52.11% (n=185) were basketball referees, 32.11% (n=114) were Football referees, and 15.77% (n=56) were handball referees. There were 35 (9.86%) female and 320 (90.14%) male referees. The mean age and seniority of the participants were 31.12 and 10.21 years, respectively. Data analysis was done using the SPSS 21 and AMOS programs. Principal component analysis and varimax rotation techniques were used to test the scale's construct validity. Criterion validity was calculated with Pearson's correlation coefficient. As a result, a two-factor structure with eigenvalues greater than one emerged. Internal consistency coefficients were calculated as .83 for the Cognitive Reappraisal and .76 for the Suppression. The CFA analysis revealed x2/df=1.603, RMSEA=.07, CFI=.96, GFI=.93, RMR=.10 NFI=.90, and IFI=96. Overall, the study suggested that the Emotion Regulation Scale for Referees (ERSR) was a valid and reliable tool to measure emotion regulation among referees.

Psychometric analysis of the body responsiveness questionnaire in the Portuguese population

Body responsiveness refers to the tendency to be attuned to the body’s needs and use interoceptive information to guide behavior. Despite its potential beneficial effect on the development of positive body image, this construct is currently understudied. To boost research in this area, we examined the factor structure, gender invariance, and psychometric properties of a Portuguese translation of the Body Responsiveness Questionnaire (BRQ). A total of 650 men and women (aged 18–80 years) completed the Portuguese BRQ. To assess its convergent validity, participants also completed measures of body appreciation, emotion regulation, depression symptoms, and psychological quality of life. Exploratory factor analysis indicated a two-factor structure of the BRQ, which was upheld using confirmatory factor analysis: “Importance of Interoceptive Awareness” (ω = .85–.87) and “Perceived Connection” between body and mind (ω = .71–.74). BRQ scores had partial scalar invariance across gender, and no significant gender differences. Convergent and known-groups validity was supported. Participants with overweight/obesity (vs. normal weight) and middle-aged adults (vs. young adults) assigned higher importance to body signals to guide behavior. The Portuguese version of the BRQ is a psychometrically sound measure of body responsiveness and it may contribute to a comprehensive assessment of positive body image to guide intervention.

Development and adaptation of the Emotion Regulation Skills Questionnaire for adolescents.

The ability to effectively regulate one's emotions is important for adolescent mental health. However, extant assessments of how adolescents regulate their emotions can be expanded upon in several ways, including incorporating more strategies (e.g., cultural and spiritual) and positive emotions, and being informed by adolescents and expert consultation during the development process. Thus, our study aimed to improve the construct validity of an emotion regulation measure by adapting and refining the Emotion Regulation Skills Questionnaire (ERSQ) into an adolescent self-report. We recruited 2413-17-year-olds (12 males; 11 females; 1 gender fluid) via social media advertisement in the United States in 2020. We used an iterative qualitative approach in which we combined expert consultation, cognitive interviewing with adolescents, and top-down and bottom-up coding to review and provide feedback on the ERSQ. Findings of thematic analysis showed that a need for clarity in wording and inclusion of strategy examples across all sections of the ERSQ was needed. Adolescents also identified the need to replace the Silly/Excited section with a more age-appropriate positive emotion section. Findings indicate cognitive interviewing can be successfully completed in a virtual format when necessary, youth utilize a wider range of strategies to maintain or upregulate positive emotions than what is represented in current measures, and use of qualitative methods may have reduced construct underrepresentation and construct-irrelevant variance in the adapted ERSQ.

DIFFERENT ASSOCIATIONS BETWEEN HEART RATE VARIABILITY AND EMOTION REGULATION IN OLDER AND YOUNGER ADULTS

Abstract Heart rate variability (HRV), the beat-to-beat variation in heart rate, is proposed to index aspects of self-regulatory processes such as emotion regulation. This is due to overlapping neural regions and networks that contribute to the central autonomic and emotion regulation systems. Paradoxically, increasing age is associated with both improvement in emotion regulation and decline in HRV, and it is unclear whether and how the association between HRV and emotion regulation is influenced by aging. The earliest stages of neurodegenerative processes, such as Alzheimer’s disease-related reduction of locus coeruleus (LC) integrity, may also influence the HRV-emotion regulation relationship in older adults, as LC modulates arousal and autonomic activity in response to stress. We pre-registered a study to investigate the cross-sectional relationship between measures of emotion regulation, HRV and LC MRI integrity in a lifespan sample of cognitively normal healthy adults using the Cambridge Centre for Ageing and Neuroscience (Cam-CAN) dataset, a large population-based cohort aged between 18-88 years (N=678). We hypothesized that any age-related differences in the association between HRV and emotion regulation would be related to reduced LC integrity in older versus younger adults. We found an inverse correlation between resting HRV and measures of emotional reappraisal in older adults, which differed significantly to younger adults, but no evidence of LC influence on this association. Our findings highlight age-related differences in the HRV-emotion regulation relationship which warrant further investigation in future studies.

Assessing Emotion Regulation across Asian and Western Cultures: Psychometric Properties of Three Common Scales across Singaporean and Australian Samples

Given the differences in emotion regulation across cultures, it is paramount to ensure that measures of emotion regulation measure the same construct and that conceptualizations of emotion regulation are valid across cultures. Therefore, the present study assessed the measurement invariance (alongside other psychometric properties) of three popular emotion regulation questionnaires, the Emotion Regulation Questionnaire (ERQ), Difficulties in Emotion Regulation Scale (DERS), and the Perth Emotion Regulation Competency Inventory (PERCI), across 434 Singaporeans and 489 Australians. Our study showed that all three questionnaires were measurement invariant, had excellent internal consistency, and relatively good concurrent validity with psychopathology and alexithymia across our Singaporean and Australian sample, justifying their use in comparing Asian and Western cultures. Our findings suggest that measures of emotion regulation have utility across both individualistic and collectivistic cultures. Our findings supports the use of these measures in cross-cultural research and provides support for the utility for personality assessments across cultures.

Indonesian emotion regulation scale for students based on reappraisal and suppression factor: The Rasch analysis

&lt;span lang="EN-US"&gt;Every human being has emotional turmoil, which will be a serious problem if they cannot control it. The importance of emotion regulation has become one of the bases for developing a measure of emotion regulation for students, the Indonesian emotion regulation scale (IERS). No research yet describes an instrument that measures students’ level of emotion regulation in Indonesia. IERS consists of nine items in two aspects: reappraisal and suppression factor. The content validity test involves two experts in the field of psychometrics. In comparison, the construct validity test involved 354 high school students in Yogyakarta, Indonesia. Data analysis using inter-rater reliability (IRR) coefficient of Cohen’s kappa and Rasch analysis. Based on the study of the IRR coefficient of Cohen’s kappa, two experts agree on the acceptability of the IERS statement items. Besides that, the results of the application of Rasch analysis show that IERS is good, precise, and conforms with the model. IERS is a reliable and valid tool to measure students’ level of emotion regulation accurately. This paper discusses the implications and recommendations for further research for the implementation of guidance and counseling containing the value of emotion regulation as a follow-up to the performance of IERS.&lt;/span&gt;

How does emotion regulation change during psychotherapy? A daily diary study of adults in a transdiagnostic partial hospitalization program.

Improvement in emotion regulation is a proposed transdiagnostic mechanism of change. However, treatment research is limited by disorder-specific investigations that assess a narrow number of emotion regulation strategies. Moreover, most assess pre-to-post-treatment change without examining short-term changes throughout psychotherapy that might influence treatment response. To address these gaps, this study uses daily diary methodology to examine trajectories of change in use of six emotion regulation strategies during partial hospitalization psychiatric treatment. Treatment was rooted in cognitive behavioral principles and included skills adapted from empirically supported cognitive behavioral therapy (CBT) and dialectical behavior therapy (DBT) manuals. Participants were adults (N = 364; Mage = 34.6 years; 60% female; 85% non-Hispanic White) with various profiles of mood, anxiety, and obsessive-compulsive disorders who completed symptom measures at baseline and discharge and daily measures of emotion regulation. In the first 7 treatment days, patients increased use of engagement strategies (reappraisal, acceptance) and decreased use of disengagement (expressive suppression) and cognitive perseveration (experiential avoidance, rumination) strategies. Day-to-day trajectories found that decreased use of experiential avoidance predicted next-day changes in distraction and suppression use. In predicting treatment outcomes, steeper rates of decreased suppression use predicted reductions in anxiety, depression, and general psychopathology symptoms; similar patterns were observed for decreased rumination and experiential avoidance use and increased reappraisal use. Results add to a growing literature on the value of intentional, constructive engagement with emotional experiences as a mechanism of psychological health.
