Daily Variation in Sleep Duration, Affect and Emotions in Croatian Youth: An Ambulatory Assessment

Introduction: Sleep habits are related to mood stability and mental health, and adolescence may be an appropriate time to address disturbed sleep patterns because it is a critical period for the onset of psychological problems. Aims: This study had two aims, namely: to explore associations between objectively measured sleep duration and positive and negative affect, as well as specific positive and negative emotions at the within-person and between-person levels in Croatian adolescents. Methods: In the present eight-day study, 102 Croatian adolescents with an average age of 15 years reported how they felt once a day, while sleep duration was objectively measured by collecting data from an accelerometer on participants’ smartphones. Results: Multilevel analyses showed that adolescents express more positive affect (Est. = 0.10, p < .050) and feel less distracted (Est. = -0.12, p < .050) and happier (Est. = 0.11, p < .050) on days when they sleep longer, with a multiverse analysis suggesting that these results are moderately robust. In addition, they express higher levels of negative affect, stress and distraction on school days, and boys seem to experience more positive and fewer negative emotions. Conclusions: A better understanding of daily variations in sleep duration, sleep quality, and affect would promote the development of individualized, particularly smartphone-based, sleep interventions. Such interventions could be a valuable tool for preventing mental health problems in adolescence.

DAILY STRESS PROCESSES, PHYSICAL ACTIVITY, AND SLEEP IN OLDER ADULTHOOD

Abstract Older adults who engage in healthy behaviors such as being physically active and sleeping well report lower levels of stress. Less is known about the links between exposure and reactivity to stressful events in daily life and their relationship with physical activity and sleep. The current study examined within-person associations between daily physical activity, sleep, and exposure and affective reactivity to naturally occurring interpersonal stressors. Older adults (N = 180) from the Daily Experiences and Well-being Study completed ecological momentary assessments (EMAs) every 3 hours for 5-6 days where they reported negative affect throughout the day and interpersonal tensions at the end of the day. They also reported their nightly sleep quality and wore Actical accelerometers to capture physical activity. Older adults reported greater numbers of stressors on days when they spent less time being sedentary and engaged in more light physical activity. On days when older adults experienced more stressors, they reported higher levels of negative affect, but this association was attenuated when they were more physically active that day. Additionally, older adults reported lower sleep quality the night after they reported higher numbers of stressors. These findings underscore the importance of assessing physical activity, sleep and stressful events in daily life and have implications for both physical and psychological well-being.

Irritability and Temperament: Concurrent and Prospective Relationships in Childhood and Adolescence

ABSTRACT Objective Irritability symptoms are closely associated with, and may reflect, temperament traits, particularly negative affectivity (NA). However, there are few empirical data on the relationships between child temperament and irritability symptoms. Method We investigated cross-sectional and longitudinal relationships between irritability symptoms and temperament traits from age 3–15 in a community sample of 609 children and their parents. Irritability symptoms were assessed through structured interviews with parents at ages 3/6, and inventories completed by parents and youth at ages 12/15. Temperament traits were assessed using parent reports at ages 3/6, and parent and child reports at ages 12/15. Path analysis and structural equation modeling were used to explore longitudinal associations from ages 3–6 and 12–15, respectively. Results Higher levels of irritability symptoms at ages 3/6 were concurrently associated with higher levels of NA and lower levels of effortful control (EC). In adolescence, higher irritability symptoms were concurrently associated with higher negative temperament and disinhibition. In longitudinal analyses from age 3–6 and 12–15, irritability symptoms showed modest but significant stability after adjusting for the stability of temperament traits. However, there were significant differences in the stability paths at age 3–6, reflecting lower stability of irritability symptoms. Finally, EC at age 3 predicted increased irritability symptoms at age 6, while irritability symptoms at age 3 predicted increased NA at age 6. Conclusion Irritability symptoms are robustly associated with both temperamental NA and difficulty regulating attention and behavior. These findings help situate irritability symptoms within widely accepted temperament/personality taxonomies.

Moody and in love? The role of neuroticism and romantic relationships for momentary affect in adolescence

The affective lives of adolescents are unique in that momentary affect in this age group is more negative and variable. This study examined how neuroticism and romantic relationships (i.e., relationship involvement and relationship quality) relate to adolescents’ daily affective experiences. In a weeklong experience sampling period, 408 German adolescents ( MAge = 16.83) reported up to five times per day on their positive and negative affect. We estimated mixed-effects location scale models to analyze interindividual differences in adolescents’ affect level and variability. Adolescents with higher neuroticism experienced lower levels of positive affect, higher levels of negative affect, and higher variability of positive and negative affect. Whereas adolescents with a romantic partner did not differ from their single peers with regard to affect level, they experienced higher affect variability, although evidence for these effects was weak. Finally, among adolescents who were currently involved in a romantic relationship, those with higher relationship quality experienced more variability in their positive affect if they scored higher in neuroticism. Across models, effect sizes systematically differed between affect level and variability, positive and negative affect, as well as neuroticism facets. We discuss these findings in light of adolescents’ affective dynamics, affective development, and personality-social relationship interactions.

A longitudinal test of problematic alcohol use and binge eating among college women: The moderating role of shame

Problematic alcohol use and binge eating frequently co-occur. High levels of negative affect, negative urgency, and/or shame may increase the likelihood that problematic alcohol use and binge eating co-occur over time. ObjectiveExamine 1) the temporal relationship between problematic alcohol use and binge eating among college women, who are at high risk for both, and 2) the additive and moderating effects of shared, emotion-based risk factors in models involving both problematic alcohol use and binge eating. MethodIn n = 302 college women assessed at two time points across 8 months, we used hierarchical linear regression to invstigate our objectives. ResultsBaseline problematic alcohol use and baseline shame independently predicted increases in follow-up binge eating, controlling for baseline binge eating. In addition, the interaction between problematic alcohol use and shame accounted for further variance in subsequent binge eating (the influence of baseline problematic alcohol use on follow-up binge eating was stronger at higher levels of baseline shame). The reciprocal relationship was not significant: baseline binge eating did not predict follow-up problematic alcohol use independently or in conjunction with risk factors. Neither negative affect nor negative urgency showed predictive effects beyond prior behavior and shame. Results support 1) problematic alcohol use as a prospective risk factor for binge eating, 2) shame as an additive predictor of binge eating, and 3) shame as a positive moderator of binge eating prediction from problem drinking. ConclusionAddressing shame and problematic alcohol use may be warranted in binge eating interventions for college women.

50 Sex differences in psychological features in adolescents after concussion

Objective:Few concussion studies have investigated the psychological domain of concussions. Of the 22 postconcussion symptoms assessed on the Graded Symptom Checklist of the SCAT-5, five do not overlap with core symptoms of anxiety and depression. 43% of patients report at least one psychiatric symptom, the median is four after injury. Previous studies focus on total scores and not individual items; furthermore, few consider resilience as part of psychological factors that impact recovery. This research aims to describe general and specific characteristics of psychological functioning in males/females ages 12-18 after concussion to help guide treatment. We compared total scores for each measure between males/females and looked at the differences between the genders for individual items in each measure.Participants and Methods:Participants were evaluated at an outpatient concussion clinic participating in the North Texas Concussion Registry (ConTex; N=1238, 53% female, mean age=15.4 years, SD=1.16 years). The Generalized Anxiety Disorder 7-item Scale (GAD-7, the Patient Health Questionnaire-8 (PHQ-8), the Brief Resilience Scale (BRS), and the Pittsburgh Sleep Quality Index (PSQI) were used to determine levels of anxiety, depression, resilience, and sleep quality.Results:Utilizing Mann-Whitney U tests (median, interquartile range) to examine group distributions for the GAD-7, PHQ-8, and BRS, females had significantly higher scores than males for the GAD (p<0.001; Female: 4, 1-9 v. Male: 2, 0-5) and PHQ (p<0.001; Female: 5, 210 v. Male: 3, 1-7). For the BRS, total scores for females were significantly lower than males (p<0.001; Female: 3.67, 3-4 v. Male: 3.83, 3.214.33). The PSQI media score was significantly different between males and females: item 2, p=.016 and item 4 p=.007 using an exact sampling distribution for U. Pearson Chi square tests were used to examine sex differences for each item of the psychological measures. Items 1-7 within the GAD-7 were significant between sexes (i.e. male or female). The seven items assess (1) Feelings of nervousness, (2) Inability to stop/control worry, (3) Worrying too much about different things, (4) Trouble relaxing, (5) Inability to sit still due to restlessness, (6) Irritability, and (7) Feeling afraid. Items 2-8 within the PHQ were significant between sexes. The items assess (2) Feeling down/depressed/hopeless, (3) Trouble falling/staying asleep, (4) Feeling tired/no energy, (5) Appetite changes, (6) Lowered/poor self-esteem, (7) Concentration issues, and (8) Feeling slowed down or unable to be still. There was a statistically significant difference between genders and Items 2 and 4 within the BRS were significant between sexes. The items assess (2) Difficulty surviving hard times and (4) Difficulty snapping back from something bad.Conclusions:Like other studies, this study found females have higher levels of negative affect (i.e., depressive and anxious symptoms). Females displayed lower resilience and reported poorer sleep. By analyzing psychiatric measures, treatment protocols can be tailored to address specific problems, and mental health difficulties can be mitigated by teaching specific coping techniques. These results suggest clinicians should consistently be providing education on depression, anxiety, sleep, and resilience, particularly to female patients, who appear at greater risk for psychological distress.

Predictors of Perceived Changes in Psychological Wellbeing among Clergy in the USA Serving in the Episcopal Church during the 2021 Covid-19 Pandemic

Abstract Applying the balanced affect model of clergy psychological wellbeing, as conceptualised by the Francis Burnout Inventory (FBI) and operationalised by The Index of Balanced Affect Change (TIBACh), this study explored the impact of seven sets of variables on individual differences in perceived changes in positive affect and negative affect among 737 clergy in the USA serving in the Episcopal Church during the Covid-19 pandemic. The seven sets of variables were: personal, psychological, contextual, ministry-related, church orientation, theological stance, and attitudinal. The data supported the balanced affect model of clergy psychological wellbeing by demonstrating how different variables predicted individual differences in negative affect and in positive affect. For example, clergywomen showed no differences from clergymen in terms of positive affect, but higher levels of negative affect; active self-supporting and retired clergy showed no differences from stipendiary clergy in terms of positive affect, but lower levels of negative affect; Evangelical clergy showed no differences in negative affect, but higher levels in positive affect. The balanced affect model provides insights into how clergy may be better supported during a pandemic.

The Paradox in Positive and Negative Aspects of Emotional Functioning Among Older Adults with Early Stages of Cognitive Impairment.

Introduction: Emotional functioning in older adults is influenced by normal aging and cognitive impairment, likely heterogeneous across positive versus negative aspects of emotional functioning. Little is known about positive emotional experiences at the early stages of cognitive impairment. Methods: We assessed different aspects of emotional functioning among 448 participants aged 65+ (Normal Control (NC) = 276, Mild Cognitive Impairment (MCI) = 103, and mild dementia of the Alzheimer type (mild DAT) = 69) and tested moderators. Results: Compared to NC, older adults with MCI and mild DAT have maintained many positive aspects of emotional functioning, despite higher levels of negative affect, sadness, and loneliness. Among the oldest-old, the mild DAT group experienced higher fear and lower self-efficacy. Discussion: Older adults at early stages of cognitive impairment can experience positive aspects of emotional functioning, such as positive affect, purpose, and life satisfaction, all of which are important buildable psychological resources for coping.

The Predictors of Negative and Positive Affect among People with Dementia: A Cross-Sectional Study.

Background and Objectives: This cross-sectional study examined the predictors of negative and positive affect among individuals with dementia. Materials and Methods: A sample of 102 Jordanian participants diagnosed with dementia was recruited from residential care facilities, and data were collected using different measures. Results: The results revealed that higher levels of negative affect were significantly associated with increased physical and verbal agitation among individuals with dementia. Conversely, lower levels of positive affect were associated with residing in a nursing home. Conclusions: These findings highlight the importance of recognizing the impact of both negative and positive affect on the well-being of individuals with dementia. Interventions targeting the reduction of negative affect and promoting positive affect could alleviate agitation and enhance emotional closeness in this population.

Learning through Challenges and Enigmas: Educational Escape Room as a Predictive Experience of Motivation in University Students

(1) Background. One of the most innovative gamification techniques emerging in the current educational context is the escape room, whose implementation aims to promote student motivation and learning. A review of the literature shows that many of the previous works lack a solid theoretical basis when it comes to explaining the motivational effects associated with student participation in this experience. Therefore, the aim of this study is to analyze the relationship between gamification and motivation and identify which dimensions of gamification experience—through an educational escape room—better predict students’ motivation, based on the framework of self-determination theory. (2) Methods. This research develops a quantitative and correlational methodology. A total of 135 first-year university students participated. (3) Results. The results of the regression models showed that creative thinking, activation, and dominance predicted intrinsic motivation toward knowledge, achievement, and stimulating experiences. Likewise, a higher level of negative affect was predictive of amotivation and external regulation motivation in students. (4) Conclusions. These findings provide new empirical evidence that could guide the design of educational experiences through escape rooms in the context of higher education.

Changes in Positive and Negative Affect during Creative Process Engagement

ABSTRACTThe present research examines how creative process engagement (information gathering, idea generation, idea evaluation, and idea pitch) influences the affective states of positive affect (PA) and negative affect (NA). Drawing from motivation theory and research, we proposed that creative process behaviors that are more autonomous and less constrained will increase positive affect. Additionally, creative process behaviors that are more likely to be perceived as making negative goal progress are expected to result in higher levels of negative affect. We also examine boundary conditions of these effects including task‐relevant knowledge, perceived performance, and baseline affect. Results from two studies confirm that idea generation, which is considered an autonomous activity, increases PA levels. This effect holds true across varying starting affect levels (excited, calm, and neutral). Moreover, results confirm that information search, which may be perceived as making negative goal progress, increases NA levels and PA levels decrease when task‐relevant knowledge is low. The effects of idea evaluation and idea pitch on PA and NA are mixed across the two studies. The implications of these findings for understanding how the creative process impacts affect are discussed.

Predictors and outcomes of nursing students' engagement trajectories at the beginning of their program

This study seeks to achieve a dynamic understanding of nursing students' engagement trajectories, of the predictive role of their levels of harmonious passion, obsessive passion, exposure to challenge and hindrance demands, and perceptions of institutional support in relation to their engagement trajectories. We also consider the implications of these trajectories for a variety of outcomes related to students' attitudes (i.e., dropout intentions and program satisfaction), psychological health (i.e., negative affect and life satisfaction), and behaviors (i.e., performance and absenteeism). A sample of 2515 first-year nursing students were surveyed five times, with intervals of one month, over a four-month period during the first semester of their program. Our results revealed four profiles of students presenting High and Stable, Moderate and Decreasing, Low and Decreasing, and Moderate and Stable engagement trajectories. Harmonious and obsessive passion, challenge and hindrance demands, and institutional support were associated with these trajectories in a way that mainly supported our expectations. Trajectories characterized by lower levels of engagement were associated with higher levels of negative affect and absenteeism, and with lower levels of performance, program satisfaction, and life satisfaction. Conversely, trajectories characterized by higher levels of engagement were associated with lower levels of dropout intentions and higher levels of performance.

University Experience during the First Two Waves of COVID-19: Students' Experiences and Psychological Wellbeing.

This study aimed to analyze Italian university students' psychological needs, learning experiences, and wellbeing during the first two waves of the COVID-19 pandemic. The study was carried out during the first wave of the pandemic, and then during the second. A total of 1230 university students (654 in stage 1 and 576 in stage 2) completed a battery of validated questionnaires exploring students' experiences in distance learning, perceived health risks related to COVID-19, and psychological wellbeing. MANOVA showed a significant main effect of the pandemic stage on students' learning experience and wellbeing. In particular, students were more distracted and concerned about their academic careers during the second phase of the pandemic than in the first. Furthermore, the pandemic stage also significantly affected health risk perceptions and fear of COVID-19, which were higher during the second wave of the pandemic. Female gender and concern for a university career were significant risk factors for high levels of negative affectivity and low levels of positive affectivity during the pandemic. In contrast, adherence to COVID-19 restriction measures and good family support were protective factors. It is essential to promote adequate university psychological services to support university students who have experienced the adverse psychological effects of the pandemic and enhance the resilience factors needed to improve their wellbeing in the post-pandemic period.

Approach-avoidance biases to self-harm cues in young people with self-harm

BackgroundThe urge to self-harm can be likened to craving in addictive behaviours. However, it remains unclear whether cognitive mechanisms involved in craving, such as attentional biases to cues, also underpin the urge to self-harm. MethodsA Dot Probe Task was used to investigate attentional biases to self-harm cues in young people aged 16–25 with self-harm. Cues were shown for either 0.2 s or 2 s. Dot Probe Task performance in the Self-harm group (N = 50) was compared with age-matched Healthy Controls (N = 50) and age- and negative-affect (Depression Anxiety Stress Scale-21) matched controls with no self-harm (N = 50). ResultsThe Self-harm group showed significantly greater avoidance of self-harm cues than Healthy Controls at 2 s. The Negative Affect group showed significantly less difficulty disengaging from self-harm cues than the Self-harm group and Healthy Controls at 2 s. There were no between-group differences in attentional bias at 0.2 s. LimitationsStudy limitations that may affect attentional biases in the Self-harm group include not measuring indicators of recovery and recruiting only from the community potentially missing more severe self-harm presentations in clinical settings. ConclusionsAvoidance of self-harm cues in young people with self-harm may reflect conflict around self-harm behaviour, consistent with ambivalence models of craving. An ability to disengage from self-harm cues may be a protective factor in young people with higher levels of negative affect who do not self-harm. Whether these attentional biases represent a quantifiable marker of treatment response or susceptibility to relapse in individuals with self-harm remains an area for future investigation.

Personality, psychosocial and oral behavioural risk factors for temporomandibular disorder symptoms in Asian young adults.

The relation between personality, psychosocial factors, somatisation, andoral behaviours as risk factors to temporomandibular disorder symptoms have notbeen well established. This study examined the association of temporomandibular disorder (TMD) symptoms with personality traits, psychological distress, somatisation and oral behaviours. The psychosocial and oral behavioural risk factors for TMD symptoms were also established in Asian young adults. Participants were recruited from a large private University. Based on the quintessential five TMD symptoms (5Ts) of the DC/TMD, the participants were stratified into those with no (NT), painful (PT), dysfunctional (DT) and mixed (MT) TMD symptoms. Personality traits, psychological distress, somatisation and oral behaviours were evaluated with the Big Five Inventory-10 (BFI-10), Depression, Anxiety, Stress Scales-21 (DASS-21), Patient Health Questionnaire-15 (PHQ-15) and Oral Behaviours Checklist (OBC) accordingly. Data were examined using Kruskal-Wallis/Mann-Whitney U and Chi-squared tests, as well as multivariate logistic regression analysis (α = .05). Of the 420 young adults (mean age 22.7 ± 1.1 years) evaluated, 41.4% had no TMD symptoms, while 17.4%, 20.0% and 21.2% reported PT, DT and MT, respectively. Though personality traits did not vary notably, participants with MT and PT had significantly higher levels of negative affectivity, anxiety and stress than the NT group. Moreover, those with MT and PT presented significantly greater somatisation and more oral behaviours than the DT and NT groups. Multivariate regression analyses indicated that anxiety, somatisation, sleep-related and waking-state nonfunctional oral activities were associated with painful and/or dysfunctional TMD symptoms. Except for sleep-related oral activity, psychosocial and oral behavioural risk factors differed for painful, dysfunctional and mixed TMD symptoms in Asian young adults.

The dark side of leadership: abusive supervision and its effects on Employee's behavior and well-being

PurposeThe aim of this study is to examine the impact of abusive supervision on employees' emotional and work-related outcomes, using a theoretical framework that integrates affective events theory (AET) and self-determination theory (SDT). The research sought to explore the effects of abusive supervision on subordinates' positive and negative affect, and the subsequent impact on customer orientation and life satisfaction.Design/methodology/approachThe data for this study were collected cross-sectionally through a structured questionnaire completed by employees who have experienced abusive supervision in their current or previous jobs. Structural equation modeling (SEM) was used to analyze the data.FindingsThe results indicated that when subordinates experienced abusive supervision, they reported lower levels of positive affect and higher levels of negative affect. These emotions, in turn, impacted their customer orientation and life satisfaction. Positive affect was found to positively influence both customer orientation and life satisfaction, while negative affect had a negative effect on life satisfaction. Surprisingly, customer orientation was positively impacted by negative affect.Originality/valueTherefore, the findings of this study suggest that positive and negative affects mediate the relationship between abusive supervision and life satisfaction, but not with customer orientation. This study advances prior research by linking the impact of an abusive supervisor to employees' customer behavior and life satisfaction, using positive and negative affects as mediators, and building upon the theories of AET and SDT.

Emotion regulation styles and Adolescent adjustment following a COVID-19 lockdown.

This study explored the effect of emotion regulation styles - integrative emotion regulation (IER), suppressive emotion regulation, and dysregulation-on adolescents' psychosocial adjustment following a Covid-19-related lockdown. 114 mother-adolescent dyads were surveyed after lockdown and at two additional time points (three and six months later). Adolescents were aged 10-16years, 50.9% females. Adolescents reported on their emotion regulation styles. Mothers and adolescents reported on adolescents' well-being (depressive symptoms, negative and positive emotions) and social behaviour (aggression and prosocial behaviour). Results of multilevel linear growth models showed IER predicted optimal well-being and social behaviour reported by both mothers and adolescents at baseline and a self-reported reduction in prosocial behaviours over time. Suppressive emotion regulation predicted reduced self-reported well-being after lockdown, evident in higher levels of negative affect and depressive symptoms and reductions in mother-reported prosocial behaviour over time. Dysregulation predicted reduced well-being and impaired social behaviour after lockdown, reported by both mothers and adolescents, and a reduction in self-reported depressive symptoms over time. Results suggest adolescents' adjustment to lockdown was affected by their habitual emotion regulation styles.

Chronic Pain and Affective Experiences Associated with Daily Stressors and Uplifts.

People with chronic pain often report greater reactivity to stress than those without pain. This finding is consistent with the kindling hypothesis, which states that continued exposure to stressors only heightens negative affect and dampens positive affect. Yet, people with chronic pain may also respond more positively to enjoyable activities, or uplifts, as well. Chronic pain is related to lower levels of well-being, and the fragility of positive affect model explains how individuals with lower levels of well-being often exhibit stronger, more positive responses to daily uplifts than their less distressed peers. Our study used the National Study of Daily Experiences to assess daily stressors, positive uplifts, and positive and negative affect across eight days among those with and without chronic pain. Participants (nChronicPain=658, nNoPain=1,075) were predominately Non-Hispanic White (91%), 56% female, and averaged 56 years old. Results revealed that people with chronic pain had lower levels of daily positive affect and higher levels of negative affect, yet the two groups did not vary in their stressor-related negative and positive affect. In contrast, having chronic pain was related to a greater increase in positive affect and greater decreases in negative affect on days with positive uplifts. Findings suggest that intervention efforts focusing on uplifts may be particularly helpful for people who report chronic pain.

Psychological Effects of the Pandemic on Turkish University Students During the Period of Returning to Universities

The COVID-19 pandemic may have been psychologically stressful for everyone who was affected by it, but people who are predisposed to mental health problems may have felt it more intensely than others. Students at universities are one of these vulnerable populations. The uncertainty brought on by COVID-19 had a negative psychological impact on them, but this effect became more complex in the process of restarting education after a long break. The purpose of this study is to investigate the psychological situation of Turkish university students during the period when face-to-face education began to reappear as a result of the COVID-19 precautions being reduced. For this aim, the psychological situation of 224 Turkish students aged 17–25 was assessed using the Beck Depression Inventory (BDI), State and Trait Anxiety Scale (STAT), Connor Davidson-Resilience Scale (CD-RISC), Positive and Negative Affect Schedule (PANAS), and Brief Symptom Inventory (BSI). In addition, the students were asked about their life satisfaction, chronic illness, duration of physical activity, screen time, and needs of psychological support. The results revealed that during this period, students reported low levels of exercise and physical activity time, increased time spent in front of a screen, low life satisfaction, higher rates of receiving and needing psychological support, and higher levels of negative affect, depression, anxiety, and brief symptoms. Furthermore, the results showed that positive affect and resilience are protective factors for psychological health. The findings of the study highlighted the critical role of psychological support services at universities in promoting and preserving students' mental health.

Emotion regulation strategies and aggression in youngsters: The mediating role of negative affect

Aggression in youngsters is a highly prevalent problem worldwide. Given that this problem has negative consequences for society, aggressors, and victims, the present study aims to understand the processes underlying the acts of aggression in this population. Specifically, we analyze the role of two emotional regulation strategies (cognitive reappraisal and expressive suppression) and the positive and negative affect variables in aggressive behavior. For this purpose, 654 primary and high school students aged between 9 and 18 years (47.6% boys) were assessed on emotion regulation, positive and negative affect, and aggression through the Emotion Regulation Questionnaire, the Positive and Negative Affect Schedule, and the Buss-Perry Aggression Questionnaire, respectively. The results revealed that higher use of the cognitive reappraisal strategy was correlated with lower levels of aggression (for total, physical, and anger). In contrast, the opposite was observed with expressive suppression (for total aggression and hostility). More important for the purposes of this study was the finding that the negative affect variable mediated the relationship between expressive suppression and aggressive behavior. Specifically, those individuals who made greater use of the expressive suppression strategy had higher levels of negative affect, which, in turn, was associated with higher levels of aggression. Cognitive reappraisal appeared to be only directly related with a reduction in total aggression. Thus, higher levels of cognitive reappraisal were related to a reduction in aggressive behavior. However, when focusing on the four dimensions of aggression, the relationship between cognitive reappraisal and aggression appears to be mediated by negative affect and, in the case of anger, by positive affect. The limitations and implications of these findings are discussed.
