Emotional Impulsivity and Emotional and Behavioral Difficulties Among Children With ADHD: An Ecological Momentary Assessment Study

Peer Bullying Victimization Trajectories for Sexually and Gender Diverse Youth from Early Childhood to Late Adolescence

Sexually and gender diverse (SGD) youth experience more peer bullying victimization than heterosexual, cisgender youth during adolescence, yet the emergence and persistence of these disparities remain underexplored. Also, it is unclear which factors are associated with these disparities across development, and how these disparities are linked to late adolescent health discrepancies. This study utilized the sample from the Millennium Cohort Study in Britain (N = 10,080; 51.3% assigned female at birth; Mage = 2.28, SDage = 0.46 at Wave 2), in which 23.74% of youth reported non-heterosexual attraction, 21.59% reported non-heterosexual identity, and 1.08% reported gender identity not in line with the sex assigned at birth. Using latent class growth modeling, four peer bullying victimization trajectories were identified, with early peak (7.2%), late childhood peak (6.3%), adolescence onset (12.8%), and low (73.6%) rates of victimization. SGD youth, compared to heterosexual and cisgender youth, were found to have increased odds of being in the victimization-involved classes, especially the adolescence onset class. The study further revealed that SGD youth reported more mental health and relational difficulties in childhood, which were linked to their heightened risk of longer-lasting victimization. Further, long-term victimization was found to partially account for the disparities in health and well-being for SGD youth in late adolescence. In conclusion, SGD youth were more likely to experience longer-lasting bullying victimization during childhood and adolescence, its related mental and relational vulnerabilities were already established in childhood, and such victimization disparities were further linked to their detrimental health and well-being in late adolescence. The design, hypotheses, and target analyses of the current study were preregistered on 21st April 2023 at https://osf.io/f2zxy .

Problems most concerning to parents of children with ADHD and emotional dysregulation in a randomized controlled trial of multinutrients: MADDY secondary analysis

OBJECTIVE

With dual focus on structured, objective quantification of parent observations of child's behavior and identifying behaviors most amenable to change, this report examines Parent Target Problems (PTP) as a secondary outcome in a randomized clinical trial (RCT) of children with attention-deficit/ hyperactivity disorder (ADHD) in which one primary outcome, Clinical Global Impression-Improvement, showed a significant advantage of multinutrients over placebo and the other, Likert-type parent ratings, showed significant improvement in both groups, without significant difference between them.

METHOD

In a multisite 8-week RCT of broad-spectrum micronutrients ("multinutrients"), parents of children ages 6-12 (N = 126, 73% male, 88% white) with ADHD and emotional dysregulation nominated their child's most concerning problem(s) at baseline and quantified them by frequency, duration, impairment, and consequences. At subsequent visits, parents re-quantified the problem(s). Blinded child psychiatrists independently reviewed the PTPs and rated change at two timepoints compared to baseline. PTPs were grouped into 9 categories. Mean ratings were compared between active and placebo groups and explored by category.

RESULTS

By week 8, a significant separation favored multinutrients: 38% of the multinutrient group were "definitely improved" or better, compared to 25% of the placebo group, and ratings of "no change" or "worse" occurred in 35% with placebo versus 23% with multinutrients (p = 0.04). Inattention (72.2%) and emotional dysregulation (69.1%) were the most frequently reported PTP categories. Inattention and internalizing symptoms improved more with multinutrients than placebo (p = 0.01, d = 0.55; p = 0.03, d = 0.80, respectively). The multinutrient advantage was not significant for 7 other symptoms, including hyperactivity/impulsivity, aggression, autistic symptoms, or emotional dysregulation/irritable oppositionality.

CONCLUSIONS

This secondary analysis found that the multinutrients, compared to placebo, were associated with improvements in parental concerns overall, and in two domains specifically: inattention and internalizing symptoms (anxiety/depression), but not in seven domains: hyperactivity/impulsivity, aggression, autistic symptoms or physiological symptoms, peer relationships or emotional dysregulation/irritable oppositionality.

Momentary Dynamics Implicate Emotional Features in the ADHD Phenotype

Emotional dysregulation is increasingly recognized as important to the attention-deficit/hyperactivity disorder (ADHD) phenotype alongside inattention and hyperactivity-impulsivity. Studies of ADHD have relied primarily on trait-based conceptualizations that emphasize stability of symptoms across moderate developmental timescales (i.e., months to years). Trait-based conceptualizations provide a critical view but fail to account for short-term dynamic variations in the expression of ADHD symptoms and emotion. This leaves a gap in our understanding of the short-term variation in ADHD symptom expression and the dynamic relationships among ADHD symptoms and emotion. Here, we assessed caregiver report of ADHD symptoms and positive and negative emotion using ecological momentary approaches over 2 weeks in a sample of 36 children with and without ADHD between the ages of 7-12 years old. Between-person (RKF) and within-person (RC) reliability were estimated. Multilevel models tested specific covariation hypotheses between ADHD symptoms and emotion. Analyses confirmed that ADHD and emotion ratings were reliable as individual differences (i.e., between-person; RKF range 0.93-1.0) and moment-to-moment change (i.e., within-person; Rc range 0.66-0.88) measures. Multilevel models found little evidence for lagged effects between domains, but consistently identified concurrent expression of ADHD symptoms and emotions; inattention covaried most strongly with negative emotion and hyperactivity-impulsivity covaried most strongly with positive emotion. Results demonstrate the importance of complementing trait-level conceptualizations with assessment of momentary dynamics. Momentary assessment suggests important covariation of ADHD symptoms and emotion as part of the ADHD phenotype.

[Effect of Emotion Regulation on Anxiety/Depression Symptoms in Children With Attention-Deficit/Hyperactivity Disorder: The Mediating Role of Social Problems and the Moderating Role of Family Functioning]

Objective

To investigate the mediating effect of social problems in the effect pathway of emotional dysregulation influencing anxiety/depression emotions in children with attention-deficit/hyperactivity disorder (ADHD) and to explore the potential moderating effect of family functionality.

Methods

A total of 235 children diagnosed with ADHD were enrolled in the study. The paticipants' age ranged from 6 to 12. Emotion Regulation Checklist, Achenbach's Child Behavior Checklist (CBCL) Social Problems Subscale, CBCL Anxious/Depressed Subscale, and Family Assessment Device were used to evaluate the emotional regulation, social problems, anxiety/depression emotions, and family functionality of the participants. A moderated mediation model was employed to analyze whether social problems and family functionality mediate and moderate the relationship between emotional regulation and anxiety/depression emotions.

Results

Social problems partially mediated the impact of emotional dysregulation on anxiety/depression emotions in ADHD children, with the direct effect being 0.26 (95% confidence interval [CI]: [0.17, 0.36], P<0.001), the indirect effect being 0.13 (95% CI: [0.07, 0.19], P<0.001), and the mediating effect accounting for 33% of the total effect. Family functionality exhibited a positive moderating effect on the relationship between social problems and anxiety/depression emotions.

Conclusion

This study contributes to the understanding of complex factors influencing anxiety/depression in children with ADHD, providing reference for the further development of targeted interventions for children with ADHD and the improvement of prognosis.

Children's emotional reactivity and negative affect predict future ADHD symptom severity beyond initial ADHD symptom severity

Children with Attention-Deficit/Hyperactivity Disorder (ADHD) often experience significant emotion dysregulation. However, there is limited longitudinal data on associations between multiple aspects of emotion dysregulation and ADHD symptoms. Additionally, given substantial evidence that increased levels and variability of negative affect (NA) are identified in children with ADHD, it is important to examine the role of NA in this relationship. The present study used momentary and longitudinal data to examine the relation between two aspects of emotion dysregulation (emotional lability and emotional reactivity), the two ADHD symptom clusters separately (inattentive and hyperactive/impulsive), total ADHD symptom severity, and NA variability over a period of six months. Participants (N = 68) were parents of children aged 7-12 years old (M = 9.80, SD = 1.34) who completed baseline and 6-month follow-up reports of children's ADHD symptoms and emotion dysregulation as well as ecological momentary assessments (EMA) of their children's NA for one week. Results were threefold: (1) children's emotional reactivity predicted inattentive, hyperactive/impulsive, and total ADHD symptom severity above and beyond initial ADHD symptom severity, but emotional lability did not significantly predict severity of any ADHD symptom cluster; (2) NA variability predicted hyperactive/impulsive and total ADHD symptom severity, but not inattentive severity; and (3) initial ADHD symptom severity did not predict emotion dysregulation at follow-up. The current study provides novel insight regarding the longitudinal influence of specific aspects of emotion dysregulation and NA on ADHD symptom severity in children and suggests that targeting emotional reactivity could minimize ADHD symptom severity.

Daily Associations Between Sleep and Affect in Youth at Risk for Psychopathology: The Moderating Role of Externalizing Symptoms

Problems with sleep, emotion regulation, and externalizing psychopathology are interrelated, but little is known about their day-to-day associations in youth. We examined self-reported daily sleep quality as a bidirectional predictor of next-day positive and negative affect (PA/NA), with externalizing symptoms as a moderator. Data were drawn from an ecological momentary assessment (EMA) study involving 82 youths (ages 9-13; 50% female; 44% White, 37% Black/African American) at high (n = 41) or low (n = 41) familial risk for psychopathology. Parents rated youths' externalizing symptoms at baseline. Youths then completed a 9-day EMA protocol, reporting sleep quality 1x/day and affect 4-8x/day. Daily means, peaks, and variability in PA and NA were computed. Multilevel models examined bidirectional associations between sleep and affect (between- and within-person), testing externalizing symptoms as a moderator and controlling for age and sex. In models of sleep predicting affect: Within-person, poorer-than-usual sleep quality predicted greater variability and higher peaks in next-day NA, but only for youth with higher levels of externalizing symptoms. Between-person, poor sleep quality and higher levels of externalizing symptoms predicted lower mean and peak PA. In models of affect predicting sleep: Within-person, lower-than-usual mean PA predicted poorer subsequent sleep quality, but only for youth with higher levels of externalizing symptoms. Between-person, youths with higher mean and peak PA had better sleep quality. These findings suggest that affective functioning is bidirectionally linked to daily self-reported sleep quality among high- and low-risk youth. Specific disturbances in daily sleep-affect cycles may be distinctly associated with externalizing psychopathology.

Exploring the effect of ADHD traits on the moment-to-moment interplay between provocation and aggression: Evidence from dynamic structural equation modeling

The relation between attention deficit hyperactivity disorder (ADHD) symptoms and aggression is well documented; however, the processes that account for higher levels of aggression associated with ADHD in the course of daily life are little understood. The current study used ecological momentary assessment to explore how ADHD traits relate to individual differences in perceiving provocation from others and the resultant aggressive behaviors; and the strengths of the links between provocation and aggression in the flow of daily life. A dynamic structural equation model was fit using data from a subpopulation of young adults involved in the longitudinal z-proso study (n = 259, median-age 20). Data on provocation and aggression was collected at four quasi-random time periods per day over a 14-day period. Individuals with higher ADHD trait levels reported higher instances of provocation and aggression, with ADHD traits significantly moderating aggression inertia such that those with higher levels of ADHD traits showed greater persistence of aggressive behavior over time. However, ADHD trait levels did not significantly moderate any of the observed cross-lagged effects. Our findings suggest that individuals with higher levels of ADHD traits are at greater risk of exposure to interpersonal interactions involving interpersonal provocation, show higher levels of aggressive behavior in daily life, and find it more difficult to reduce their aggression once triggered. These findings support the importance of targeting factors such as social skills and emotion regulation that may underpin the increased difficulties in interpersonal interactions often experienced by individuals with high levels of ADHD symptoms.

Building an ecological momentary assessment smartphone app for 4- to 10-year-old children: A pilot study

OBJECTIVE

Ecological momentary assessment (EMA) minimizes recall burden and maximizes ecological validity and has emerged as a valuable tool to characterize individual differences, assess contextual associations, and document temporal associations. However, EMA has yet to be reliably utilized in young children, in part due to concerns about responder reliability and limited compliance. The present study addressed these concerns by building a developmentally appropriate EMA smartphone app and testing the app for feasibility and usability with young children ages 4-10 (N = 20; m age = 7.7, SD = 2.0).

METHODS

To pilot test the app, children completed an 11-item survey about their mood and behavior twice a day for 14 days. Parents also completed brief surveys twice a day to allow for parent-child comparisons of responses. Finally, at the end of the two weeks, parents provided user feedback on the smartphone app.

RESULTS

Results indicated a high response rate (nearly 90%) across child surveys and high agreement between parents and children ranging from 0.89-0.97.

CONCLUSIONS

Overall, findings suggest that this developmentally appropriate EMA smartphone app is a reliable and valid tool for collecting in-the-moment data from young children outside of a laboratory setting.

Examining the influence of irritability and ADHD on domains of parenting stress

Parents of children with ADHD typically report higher levels of parenting stress than parents of typically developing children. Children with ADHD display developmentally inappropriate levels of hyperactivity, impulsivity, and inattention. Some children with ADHD are also prone to particularly high levels of tonic irritability that may explain some of the impairments typically found in ADHD. The present study sought to determine the unique impact of ADHD and tonic irritability on child-related parenting stress domains (e.g., difficult child, parent-child dysfunctional interactions). 145 mothers of children with and without ADHD aged 7-12 years participated in the current study. Mothers completed self-report measures of parenting stress as well as a diagnostic structured interview. Ecological momentary assessment (EMA) was used to assess tonic irritability in an ecological environment. Indirect effects models were specified using PROCESS Model 4. For the parent-child dysfunctional interaction domain, the data were best fit by a model specifying a significant total effect of ADHD that was fully accounted for by an indirect effect through irritability. For the difficult child domain, model testing indicated a significant total effect of ADHD that was partially accounted for by an indirect effect through irritability. The current study adds support to the growing body of literature acknowledging the role of tonic irritability in children with ADHD. Furthermore, the results provide novel insight in the complex relation of irritability, child ADHD, and domains of parenting stress.

Does emotion dysregulation mediate the association between ADHD symptoms and internalizing problems? A longitudinal within-person analysis in a large population-representative study

BACKGROUND

Previous research has suggested that children with attention-deficit/hyperactivity disorder (ADHD) symptoms commonly show emotion dysregulation difficulties. These difficulties may partly explain the strong tendency for internalizing problems such as anxiety and depression to co-occur with ADHD symptoms. However, no study has yet provided a longitudinal analysis of the within-person links between ADHD symptoms, emotion dysregulation, and internalizing problems necessary to examine this hypothesis from a developmental perspective.

METHODS

We used data from the age 3, 5, and 7 waves of the large UK population-representative Millennium Cohort Study (n = 9,619, 4,885 males) and fit gender-stratified autoregressive latent trajectory models with structured residuals (ALT-SR) to disaggregate within- and between-person relations between ADHD symptom, emotion dysregulation, and internalizing problem symptoms.

RESULTS

We found that emotion dysregulation significantly mediated the longitudinal within-person association between ADHD symptoms and internalizing problems.

CONCLUSIONS

Results underline the promise of targeting emotion dysregulation as a means of preventing internalizing problems co-occurring with ADHD symptoms.

Differential diagnoses of irritability and temper loss in a 6-year-old

Irritability and temper loss are common concerns among young children seen for mental health diagnostic evaluations and represent features of nearly a dozen childhood mental health conditions. Thus, careful assessment of irritability and temper loss is essential for informing case conceptualization, diagnosis, and treatment recommendations. The current case study provides a clinical description of a 6-year-old Black male ("Tyler") seen in a tertiary pediatric medical center for concerns related to significant inattention, hyperactivity, impulsivity, oppositional behaviors, irritability, and severe temper loss displayed at home and school. The clinical description summarizes findings from rating scales and diagnostic evaluations, case conceptualization, as well as treatment recommendations. Detailed suggestions for clinicians regarding strategies for assessing irritability and temper loss and questions to consider when seeking clarification to inform differential diagnoses are provided.

Micronutrients for Attention-Deficit/Hyperactivity Disorder in Youths: A Placebo-Controlled Randomized Clinical Trial

OBJECTIVE

To evaluate whether micronutrients (vitamins/minerals) benefit attention-deficit/hyperactivity disorder (ADHD) and irritability in a North American pediatric sample.

METHOD

A 3-site, 8-week, placebo-controlled, randomized clinical trial of micronutrients was conducted in nonmedicated children aged 6 to 12 years with ADHD and at least 1 impairing irritability symptom by parent report on the Child and Adolescent Symptom Inventory-5 (CASI-5). A priori-defined primary outcomes were Clinical Global Impression-Improvement (CGI-I) (CGI-I of 1 or 2 = treatment responder) and parent-rated CASI-5 composite score of ADHD, oppositional defiant, disruptive mood dysregulation, and peer conflict symptoms, including impairment scores.

RESULTS

Of 135 randomized (mean age 9.8 years), 126 youths (93%) comprised the modified intention-to-treat population. Blinding was maintained. For the CGI-I, 54% of the micronutrient and 18% of the placebo group were responders (risk ratio = 2.97, 97.5% CI = 1.50, 5.90, p < .001). CASI-5 composite scores improved significantly for both groups (p < .01), with a mean change of -0.31 (95% CI = -0.39, -0.23) in the micronutrient group and a mean change of -0.28 (95% CI = -0.38, -0.19) in the placebo group. However, the between-group difference was not significant (mean change = -0.02; 97.5% CI = -0.16, 0.12, effect size = 0.07, p = .70). The micronutrient group grew 6 mm more than the placebo group (p = .002). No serious adverse events or clinically significant changes from baseline in blood and urine tests occurred.

CONCLUSION

Micronutrients showed global benefit over placebo by blinded clinician rating, but not by parent-report CASI-5 composite rating in a population with ADHD and irritability. Micronutrients showed greater height growth. Micronutrients were well tolerated, and the majority of participants adhered to the number of capsules prescribed. This randomized controlled trial replicates safety and efficacy reported for ADHD in 2 smaller trials of a similar formula containing all vitamins and known essential minerals in amounts between the Recommended Dietary Allowance and Upper Tolerable Intake Level.

Efficacy of cognitive behavioral therapy on aggressive behavior in children with attention deficit hyperactivity disorder and emotion dysregulation: study protocol of a randomized controlled trial

BACKGROUND

Attention deficit hyperactivity disorder (ADHD) is frequently associated with emotional dysregulation (ED). ED is characterized by excessive and inappropriate emotional reactions compared to social norms, uncontrolled and rapid shifts in emotion, and attention focused on emotional stimuli. Few studies have evaluated non-pharmacological interventions to improve ED in children with ADHD. The current randomized controlled trial assesses the efficacy of a cognitive behavioral therapy (CBT) intervention compared with a theater-based intervention (TBI) in children with ADHD and ED.

METHODS

Sixty-eight 7- to 13-year-old children with ADHD and ED will be recruited and randomly assigned to the CBT or TBI group. CBT aims to reduce ED by teaching anger management strategies. TBI seeks to reduce ED by improving emotion understanding and expression through mimics and movement. In both groups, children participate in 15 1-h sessions, and parents participate in 8 sessions of a parent management program. The primary outcome measure is the change in the "Aggression" sub-score of the Child Behavior Checklist (CBCL). Secondary outcome measures include overall impairment (Children's Global Assessment Scale, Strengths and Difficulties Questionnaire), personality profile (Hierarchical Personality Inventory for Children), executive function (Behavioral Rating Inventory of Executive Function), quality of life (Kidscreen-27), parental stress (Parenting Stress Index, 4th edition), parental depression (Beck Depression Inventory-II), and impact of child disorders on the quality of the family life (Parental Quality of Life and Developmental Disorder).

DISCUSSION

Children with ADHD and ED are at risk of functional impairment and poor outcomes and have specific therapeutic needs. This randomized controlled trial wants to assess non-pharmacological treatment options for this population.

Youth Psychopathology in Daily Life: Systematically Reviewed Characteristics and Potentials of Ecological Momentary Assessment Applications

Traditionally, symptoms of youth psychopathology are assessed with questionnaires, clinical interviews, or laboratory observations. Ecological Momentary Assessment (EMA) could be a particularly valuable additional methodology, since EMA enables examining the daily lives of youths near real-time, considering fluctuations and specific contexts of symptoms. This systematic review aimed to review the characteristics of current EMA applications and to provide a synthesis of their potential in studying youth psychopathology. Following a systematic search in PsycInfo and Medline, we identified 50 studies in clinical samples. Most studies used EMA to examine fluctuations in symptoms, affect, and behavior, and the relation with contextual factors. EMA was also used to investigate interactions between parents and their children over time, and to monitor and predict treatment response. EMA appeared feasible in youth and could provide valuable insights that contribute to understanding youth psychopathology. Benefits, gaps, and suggestions for future research and clinical practice are discussed.

Reciprocal Developmental Relations Between ADHD and Anxiety in Adolescence: A Within-Person Longitudinal Analysis of Commonly Co-Occurring Symptoms

Objective: Significant anxiety often occurs in the presence of ADHD symptoms; however, the reasons are not well understood. We aimed to establish whether the relations between ADHD symptons and anxiety are bidirectional or unidirectional.

METHOD

Weexamined the developmental relations between ADHD and anxiety symptoms across adolescence (ages 13, 15, and 17) in a community-ascertained, normative longitudinal sample of 1,483 youth (52% male). We used an autoregressive latent trajectory model with structured residuals (ALT-SR) to examine within-person developmental relations between ADHD and anxiety symptoms to determine whether it is ADHD symptoms that lead to anxiety symptoms and/or the reverse.

RESULTS

Results suggested that there are reciprocal within-person developmental relations between ADHD and anxiety symptoms.

CONCLUSIONS

Our findings support the recommendation that targeting ADHD symptoms can be fruitful for addressing anxiety symptoms; however, they suggest that targeting anxiety symptoms may also benefit ADHD symptoms. Results also underline the importance of careful assessment for underlying ADHD symptoms among adolescents presenting with anxiety.

Relationship of parent-rated and objectively evaluated executive function to symptoms of posttraumatic stress and attention-deficit/hyperactivity disorder in homeless youth

Compared to their stably housed peers, homeless, and highly mobile (HHM) youth experience disproportionately greater adversity and risk leading to a wide variety of poor developmental outcomes, and targeted interventions have the potential to mitigate such outcomes. A growing literature highlights the need for accurate diagnosis in high-risk populations given the considerable overlap between posttraumatic symptomology and behaviorally based disorders such as ADHD. Objective testing inferring neurobiological and circuit-based abnormalities in posttraumatic stress disorder (PTSD) and ADHD may provide a useful clinical tool to aid accurate diagnosis and treatment recommendations. This novel, exploratory study examined the relation between executive function (EF) as measured by objective testing and parent ratings with symptoms of posttraumatic stress and ADHD in 86 children (age 9 to 11) living in emergency homeless shelters. Parent-rated EF problems suggested broad impairment associated with ADHD symptoms but specific impairment in emotional/behavioral function associated with posttraumatic stress symptoms. While measures of inhibition and shifting EF were strongly associated with symptomology in bivariate correlations, they explained minimal variance in regression models. Internalizing behavior problems were associated with posttraumatic stress symptoms, while externalizing behavior problems were associated with ADHD symptoms. Implications for clinical practice and future research are discussed.

To what extent does emotional dysregulation account for aggression associated with ADHD symptoms? An experience sampling study

Previous research suggests that aggression is associated with ADHD symptoms and this may partly reflect problems with emotional regulation. Using data from the D2M study (n=260) we found that ADHD symptoms were associated with both emotional lability and aggression, but emotional lability did not mediate the ADHD-aggression association. Results suggest that other factors may be more important for explaining elevated levels of aggression in ADHD.

Using e-diaries to investigate ADHD - State-of-the-art and the promising feature of just-in-time-adaptive interventions

Attention-deficit/hyperactive disorder (ADHD) is characterized by symptoms which are dynamic in nature: states of hyperactivity, inattention and impulsivity as core symptoms, and emotion dysregulation as associated feature. Although tremendous work has been done to investigate between-subject differences (how patients with ADHD differ from healthy controls or patients with other disorders), little is known about the relationship between symptoms with triggers and contexts, that may allow us to better understand their causes and consequences. Understanding the temporal associations between symptoms and environmental triggers in an ecologically valid manner may be the basis to developing just-in-time adaptive interventions. Fortunately, recent years have seen advances in methodology, hardware and innovative statistical approaches to study dynamic processes in daily life. In this narrative review, we provide a description of the methodology (ambulatory assessment), summarize the existing literature in ADHD, and discuss future prospects for these methods, namely mobile sensing to assess contextual information, real-time analyses and just-in-time adaptive interventions.

Emotion Regulation and Children With Attention-Deficit/Hyperactivity Disorder: The Effect of Varying Phonological Working Memory Demands

Objective: Findings from extant studies of the relationship between ADHD-related emotion regulation and working memory deficits have been equivocal, and their correlational designs preclude inferences about the functional relationship between working memory demands and emotion regulation. This study aimed to experimentally examine the functional relationship between varying working memory demands and ADHD-related emotion regulation deficits. Method: Overt emotion regulation behaviors were coded while children with and without ADHD completed experimental tasks that manipulated low and high working memory demands. Results: Compared with typically developing children, children with ADHD exhibited large-magnitude overall emotion expression deficits, disproportionately greater self-criticism during high working memory conditions, and disproportionately greater positive emotion expression during low working memory demand conditions. Conclusion: These findings suggest that working memory demands are functionally related to emotion regulation deficits exhibited by children with ADHD and may explicate variability of emotion regulation difficulties related to environmental demands.

Perceived Discrimination and Aggression Among Chinese Migrant Adolescents: A Moderated Mediation Model

Previous research has showed that Chinese rural-to-urban migrant adolescents are at high risk for discrimination, negative emotions, and aggression. However, little is known about how discrimination, negative emotions, and aggression are interrelated and whether social support addressing the emotional needs of the adolescents would moderate the relationship of discrimination to aggression. This study attempts to fill these gaps. Based on prior research, it is proposed that perceived discrimination relates to reactive aggression by increasing negative emotions that foster aggressive responses to stressful events. Considering the central role that negative emotions may play, it is also hypothesized that socioemotional support provided by family, friends, and community mitigates the impact of perceived discrimination on reactive aggression by reducing negative emotions. The results obtained from the analysis of two-wave survey data collected from a probability sample of 470 migrant students aged 11-17 (46.17% female; mean age = 13.49) in China supported these hypotheses. The findings indicate that perceived discrimination fosters negative emotions, which in turn increase reactive aggression. Additionally, socioemotional support reduces the adverse impact of perceived discrimination on reactive aggression by weakening the link between perceived discrimination and negative emotions. Practical and policy implications of these findings are discussed.

An ecological momentary assessment study of the role of emotional dysregulation in co-occurring ADHD and internalising symptoms in adulthood

Previous ecological momentary assessment (EMA) research in children has suggested that emotional dysregulation problems are commonly associated with ADHD symptoms and may help explain their relatively strong co-occurrence with anxiety and depression (collectively referred to as 'internalising problems'); however, this has yet to be replicated for adults. In this study, we used data from a n=260 longitudinal cohort and EMA study, to evaluate the hypothesis that emotional dysregulation mediates the association between ADHD symptoms and internalising problems in emerging adulthood. Emotional dysregulation was based on affect data collected in near real time and in ecological context over a 14-day period, providing a measure of emotional lability in the context of participants' daily lives. Cross-sectional mediation was tested using structural equation modelling. Emotional lability significantly mediated the association between ADHD symptoms and internalising problems. Results suggest that interventions that address the emotional dysregulation aspects of ADHD are likely to be beneficial for preventing and managing secondary internalising symptoms.

Emotional Dysregulation in Children and Adolescents With Psychiatric Disorders. A Narrative Review

Background: Emotional dysregulation (ED) is a transdiagnostic construct defined as the inability to regulate the intensity and quality of emotions (such as, fear, anger, sadness), in order to generate an appropriate emotional response, to handle excitability, mood instability, and emotional overreactivity, and to come down to an emotional baseline. Because ED has not been defined as a clinical entity, and because ED plays a major role in child and adolescent psychopathology, we decided to summarize current knowledge on this topic based on a narrative review of the current literature. Methods: This narrative review is based on a literature search of peer-reviewed journals. We searched the databases ERIC, PsycARTICLES, PsycINFO and PSYNDEX on June 2, 2020 for peer reviewed articles published between 2000 and 2020 in English language for the preschool, school, and adolescent age (2-17 years) using the following search terms: "emotional dysregulation" OR "affect dysregulation," retrieving 943 articles. Results: The results of the literature search are presented in the following sections: the relationship between ED and psychiatric disorders (ADHD, Mood Disorders, Psychological Trauma, Posttraumatic Stress Disorder, Non-suicidal Self-Injury, Eating Disorders, Oppositional Defiant Disorder, Conduct Disorder, Disruptive Disruptive Mood Dysregulation Disorder, Personality Disorders, Substance Use Disorder, Developmental Disorders, Autism Spectrum Disorder, Psychosis and Schizophrenia, and Gaming Disorder), prevention, and treatment of ED. Conclusion: Basic conditions of ED are genetic disposition, the experience of trauma, especially sexual or physical abuse, emotional neglect in childhood or adolescence, and personal stress. ED is a complex construct and a comprehensive concept, aggravating a number of various mental disorders. Differential treatment is mandatory for individual and social functioning.

Assessment of a conceptually informed measure of emotion dysregulation: Evidence of construct validity vis a vis impulsivity and internalizing symptoms in adolescents with ADHD

OBJECTIVES

Despite advances in understanding associations among attention-deficit hyperactivity disorder (ADHD), emotion dysregulation (ED), and related outcomes, there is incongruity between ADHD-relevant conceptualizations of ED and available measures of ED. To assess the psychometric properties of a parent-report questionnaire of ED conceptualized as deficits in the ability to modulate the (a) speed/degree of emotion escalation; (b) expression intensity; and (c) speed/degree of de-escalation.

METHODS

Participants were 209 adolescents with ADHD (78% male; 13.5-17.8 years old [M = 15.2 SD = 0.91]). Questionnaire items were selected from parent-report scales of ED and oppositional defiant disorder and subjected to exploratory factor analysis (EFA) and validity analyses.

RESULTS

The EFA revealed two factors, with speed/degree of escalation combined with intensity as factor one, and speed/degree of de-escalation as factor two. Factor one scores were related to ADHD impulsivity symptoms but not to anxiety and depression symptoms and they remained predictors of impulsivity even in the presence of self-report ED, evincing convergent, discriminant, and incremental validity. Factor two scores were related to anxiety and depression but not impulsivity, evincing convergent and discriminant validity.

CONCLUSION

These results inform our understanding of ADHD-relevant ED in adolescence and offer avenues for future research in measurement development, as well as for understanding ED and ADHD-related impairment.

Comorbid Internalizing and Externalizing Disorders Predict Lability of Negative Emotions Among Children With ADHD

Objective: A subset of children with ADHD experience more frequent, sudden, and intense shifts toward negative emotions. The current study utilized ecological momentary assessment (EMA) to provide a valid assessment of the impact of comorbid internalizing and externalizing disorders on negative emotional lability (EL) among children with ADHD. Method: Parents of 58, 8- to 12-year-old children with ADHD were administered a diagnostic interview to assess for ADHD and for the presence of comorbid disorders. Parents completed EMA-based ratings of their child's negative emotions three times daily for a total of 28 days. Results: Children with a comorbid internalizing disorder or children with comorbid oppositional defiant disorder (ODD) experienced significantly greater EMA-derived negative EL than children without comorbid disorders over time. Children with multiple comorbidities experienced greater EL than children with single comorbidities. Conclusion: Overall, this study suggested that both comorbid ODD and comorbid internalizing disorders contribute to negative EL among children with ADHD.

Variability in Positive and Negative Affect Among Adolescents with and without ADHD: Differential Associations with Functional Outcomes

INTRODUCTION

This study examined whether adolescents with and without attention-deficit/hyperactivity disorder (ADHD) differed in affect variability and whether variability in positive and negative affect was associated with functional outcomes.

METHOD

Participants were 302 adolescents (12-14 years, Mage=13.17, 55% male; 54% diagnosed with ADHD; 82% white) and their caregivers who each completed the 10-item Positive and Negative Affect Scale via daily diaries for approximately two weeks. Multi-informant ratings of emotional, behavioral, social, and academic outcomes were assessed.

RESULTS

Adolescents with ADHD were found to experience greater variability in self- and parent-reported positive affect, fear, and distress. For adolescents with ADHD, greater variability in self- and parent-reported positive affect, fear, and distress were associated with more internalizing symptoms, greater variability in parent-reported positive affect was associated with worse social functioning, and greater variability in self- and parent-reported fear was associated with more externalizing symptoms. In contrast, greater variability in self- and parent-reported positive affect, fear, and distress were associated with better social functioning in adolescents without ADHD.

LIMITATIONS

Future work should examine affect variability in adolescents with ADHD within the same day rather than across days. The limited age range and demographic diversity of our sample may limit generalizability of findings.

CONCLUSIONS

Findings suggest the significant affect variability found among children with ADHD is also present in adolescents with ADHD and is associated with social and behavior impairment. Interventions for adolescents with ADHD should target emotion regulation abilities to help reduce the extremes of and shifts in affective experiences in this population.

The flux, pulse, and spin of aggression-related affect

Aggression is an affect-laden behavior. The within-person variability of affective states that immediately precede, accompany, and follow aggression-and their links to between-person variability in aggressive behavior and traits-remain incompletely understood. To address this gap in our understanding, we examined 8 studies in which 2,173 participants reported the negative and positive affect they experienced before, during, and after a laboratory or online aggression task. We quantified the within-person variability within (flux) and across (pulse) negative and positive affect intensity, as well as the variability in oscillations between negative and positive affect (spin). Internal meta-analyses revealed an association between aggressive behavior and traits and flux in positive affect (against our preregistered predictions). Probing this effect with piecewise growth models showed that less aggressive individuals exhibited a pronounced decrease in positive affect during aggression, as compared to before and after the act. This downward fluctuation in positive affect was attenuated among aggressive individuals, who exhibited relatively stable levels of positive aggression-related affect. Thus, stable positive affect surrounding an aggressive act and higher positive affect during the act may buttress and promote aggressive tendencies. These findings support a reinforcement model of aggressive behavior, contrast with the aggression literature's conventional focus on negative affect and the instability thereof, and point to the utility of dynamic measures of moment-to-moment affect in understanding human social behavior.

Development and Validation of the Parenting Skill Use Diary (PSUD) in a Nationally Representative Sample

Objective: We describe the development and psychometric properties of an instrument designed to assess the use of effective parenting skills reported with a daily diary. The Parenting Skill Use Diary (PSUD) was developed iteratively relying on a "common elements" approach to quantify the use of evidence-based parenting techniques for responding to child misbehaviors and positive behaviors.Method: The PSUD was administered online daily for seven days to parents/guardians of children aged 5-12. The nationally representative sample (N = 1,570) was selected to match the US population of such parents/guardians on key demographic variables.Results: The instrument demonstrated the ability to capture significant between person variability in the appropriate use of parent management skills. A weekly summary score discriminated between parents/guardians whose children screened positive versus negative for Conduct Disorder (AUC = .72) and Oppositional Defiant Disorder (AUC = .70).Conclusions: The results supported the reliability of validity of the diary as a research tool for examining mean differences.

Attention Deficit/Hyperactivity Disorder and Global Severity Profiles in Treatment-Seeking Patients with Substance Use Disorders

INTRODUCTION

Comorbid attention deficit/hyperactivity disorder (ADHD) is present in 15-25% of all patients seeking treatment for substance use disorders (SUDs). Some studies suggest that comorbid ADHD increases clinical severity related to SUDs, other psychiatric comorbidities, and social impairment, but could not disentangle their respective influences.

OBJECTIVES

To investigate whether comorbid adult ADHD in treatment-seeking SUD patients is associated with more severe clinical profiles in these domains assessed altogether.

METHODS

Treatment-seeking SUD patients from 8 countries (N = 1,294: 26% females, mean age 40 years [SD = 11 years]) were assessed for their history of DSM-IV ADHD, SUDs, and other psychiatric conditions and sociodemographic data. SUD patients with and without comorbid ADHD were compared on indicators of severity across 3 domains: addiction (number of SUD criteria and diagnoses), psychopathological complexity (mood disorders, borderline personality disorder, lifetime suicidal thoughts, or behavior), and social status (education level, occupational and marital status, and living arrangements). Regression models were built to account for confounders for each severity indicator.

RESULTS

Adult ADHD was present in 19% of the SUD patients. It was significantly associated with higher SUD severity, more frequent comorbid mood or borderline personality disorder, and less frequent "married" or "divorced" status, as compared with the absence of comorbid ADHD. ADHD comorbidity was independently associated with a higher number of dependence diagnoses (OR = 1.97) and more psychopathology (OR = 1.5), but not marital status.

CONCLUSIONS

In treatment-seeking SUD patients, comorbid ADHD is associated with polysubstance dependence, psychopathological complexity, and social risks, which substantiates the clinical relevance of screening, diagnosing, and treating ADHD in patients with SUDs.

Momentary fluctuations in impulsivity domains: Associations with a history of childhood ADHD, heavy alcohol use, and alcohol problems

BACKGROUND

The current study examined if fluctuation in in-the-moment impulsivity was more pronounced for adults with, versus without, a childhood history of ADHD and if ADHD group moderated the association between fluctuation in impulsivity and alcohol use behaviors.

METHODS

Two hundred and eleven adult drinkers (52% ADHD) completed a 10-day, 6 times/day, momentary assessment of state impulsivity. Self-reported trait impulsivity, alcohol problems, and frequency of 5+ drinks in the past 12 months were also assessed.

RESULTS

The ADHD group had more variability in three domains of state impulsivity (negative urgency, positive urgency, sensation seeking) compared to the nonADHD group. After including global trait impulsivity, the ADHD and nonADHD groups only differed on state sensation seeking. Fluctuation in two domains of state impulsivity were related to frequency of 5+ drinks (lack of planning: ADHD RR = 3.60, p < 0.001, nonADHD RR=0.90, p = 0.81; negative urgency: ADHD RR=4.32, p = 0.01, nonADHD RR=0.49, p = 0.24) and number of different alcohol problems (lack of planning: ADHD RR=4.87, p < 0.001, nonADHD RR=0.58, p = 0.29; negative urgency: ADHD RR=4.96, p = 0.01, nonADHD RR=0.24, p = 0.04) for participants with a history of ADHD but were not related (or related to fewer problems) for those without childhood ADHD. Higher variability in positive urgency was related to more alcohol problems for the participants with childhood ADHD but not the nonADHD participants (ADHD RR=3.00, p = 0.03, nonADHD RR=0.50, p = 0.25).

CONCLUSIONS

Findings highlight the importance of assessing fluctuation in several domains of impulsivity and may elucidate important treatment targets for alcohol problems for adults with ADHD histories.

Feasibility of Ecological Momentary Assessment of Negative Emotion in Girls With ADHD: A Pilot Study

This study explores the feasibility of using mobile phone ecological momentary assessment to evaluate negative emotion in adolescent girls with attention-deficit/hyperactivity disorder (ADHD). A total of 13 girls with ADHD, ages 12-16 years old (38.5% with comorbid depression), and their mothers completed several daily surveys assessing the intensity and variability of youth negative emotion using mobile phone-based ecological momentary assessment for approximately one week. The rate of response to survey prompts by youth and maternal reports was examined. In addition, associations between girls' and mothers' ratings of negative emotion were calculated. Finally, the severity and fluctuation in negative emotion were compared between girls with and without depression. Girls and their mothers demonstrated a high level of compliance with assessment procedures, and maternal and youth ratings were significantly correlated. In addition, girls with comorbid depression and their mothers endorsed significantly more intense and variable negative emotion compared to girls with ADHD alone. These preliminary findings show that ecological momentary assessment is a feasible and valid method for collecting information on emotion regulation among girls with ADHD and their mothers that can be applied to future work aimed at collecting ecologically valid assessments of functioning in girls with ADHD.

Functional Impairment Variability in Children With ADHD Due to Emotional Impulsivity

OBJECTIVE

The present study utilized ecological momentary assessment (EMA) to examine the effects of emotional impulsivity on overall functional impairment and functional impairment variability (FIV) of children with and without ADHD.

METHOD

Parents of 74 children, 8- to 12-year-olds (42 with ADHD, 32 without ADHD), completed EMA assessment protocol ratings of their child's mood (3 times daily) and functional impairment (1 time daily) over the course of 28 days.

RESULTS

Hierarchical regression analyses supported the interaction of ADHD diagnostic status and greater EMA-derived emotional impulsivity in the estimation of total functional impairment (Total FI) and FIV. Thus, greater emotional impulsivity was found to be related to greater Total FI and FIV among children with ADHD but not among children without ADHD.

CONCLUSION

This study suggests that children with ADHD and greater emotional impulsivity demonstrate greater overall levels of functional impairment, with the severity of their impairment varying significantly over time.

Are Elevations in ADHD Symptoms Associated with Physiological Reactivity and Emotion Dysregulation in Children?

The present study examined whether children with elevated attention-deficit/hyperactivity disorder (ADHD) symptoms display a unique pattern of emotion dysregulation as indexed by both parent report and physiological reactivity during experiences of failure. A sample of 61 children (9 to 13 years; M = 11.62, SD = 1.29; 48 % male) with and without clinical elevations in ADHD symptoms participated. Parent and teacher report of ADHD and oppositional defiant disorder (ODD) symptoms and parent report of internalizing problems were collected. Parents also provided ratings of children's emotional negativity/lability and emotion regulation. Children's physiological reactivity, based on changes in respiratory sinus arrhythmia (RSA) and skin conductance level (SCL), were assessed while they completed a manipulated social rejection task and impossible puzzle task. Regression analyses indicated that ADHD symptoms were associated with higher parent-rated emotional negativity/lability and with blunted RSA withdrawal in response to social rejection; these effects were not accounted for by co-occurring ODD symptoms or internalizing problems. ODD symptoms also were uniquely associated with parent ratings of poor emotion regulation. Internalizing problems were uniquely associated with emotional negativity/lability, poor emotion regulation, and increased SCL activity in response to social rejection. Results suggest that there may be a pattern of emotion dysregulation that is specific to ADHD symptomatology. The importance of contextual factors when examining physiological reactivity to stress in youth with ADHD is discussed.

A smartphone-based ecological momentary assessment of parental behavioral consistency: Associations with parental stress and child ADHD symptoms

Inconsistent parental discipline is a robust correlate of child attention-deficit/hyperactivity disorder (ADHD) symptoms, but few studies have considered the role of inconsistent positive parenting on ADHD, as well as the effects of stress on negative and positive parental consistency. This study advanced a novel ecological momentary assessment (EMA) using participant smartphones to measure parental consistency, and examined its associations with family, social, and parenting-related dimensions of stress and child ADHD symptoms. Participants were 184 kindergartners with and without ADHD and their parents. Harsh and warm dimensions of parental behavior were assessed using questionnaires, observations, and an EMA administered through parents' smartphones, which measured parent-child behaviors every day for a period of 1 week. Family, social, and parenting-related stress were assessed from questionnaires, and child ADHD symptoms were assessed from a fully structured diagnostic interview with the parent. Child ADHD symptoms were associated with variability in warm parenting behaviors, and higher levels of parenting-related stress were related to greater variability in harsh parenting behaviors. No significant interactions were detected between parental stress and child ADHD on parental variability. These findings suggest that different factors influence the consistency in parenting behavior, depending on whether positive parenting or negative parenting is assessed. Parent-based treatment programs for children with ADHD should include a stronger focus on reducing stress from parenting (e.g., teaching coping skills for parents), as this may lead to greater consistency in parental behavior more generally, and presumably better child outcomes.

The convergence and divergence of impulsivity facets in daily life

OBJECTIVE

Impulsivity appears to be best conceptualized as a multidimensional construct. For example, the UPPS-P model posits that there are five underlying facets of impulsivity. The present study examined the expression of the UPPS-P facets in daily life using experience sampling methodology. A specific goal of the study was to examine positive urgency, a facet added to the original UPPS model, and its convergence and divergence from the negative urgency facet.

METHOD

A large nonclinical sample of young adults (n = 294) completed the UPPS-P scale and was signaled to complete questionnaires assessing daily affect, cognitions, sense of self, and impulsive behaviors eight times a day for 7 days.

RESULTS

Results indicated that the UPPS-P facets are associated with disruptions in affect, cognitions, and behavior in daily life. Furthermore, all of the UPPS-P facets were associated with impulsivity in daily life. Contrary to expectation, positive urgency was associated with negative affect rather than positive affect and had a profile indistinguishable from negative urgency.

CONCLUSIONS

These results generally support a four-factor model of multidimensional impulsivity with a general overall urgency factor instead of separate positive and negative urgency facets.

Intolerance of uncertainty in children with attention-deficit/hyperactivity disorder

Intolerance of uncertainty (IU) has often been studied in the context of internalizing disorders, but no studies to our knowledge have explored the relation between IU and externalizing disorders. Given the proposed link between IU and emotion regulation, the current study sought to examine levels of IU in an externalizing clinical population with known emotion regulation difficulties-attention-deficit/hyperactivity disorder (ADHD). IU levels in this population were compared to a clinical population known to experience elevated levels of IU. Participants in present study were ninety-three children (36 anxiety disorder, 28 ADHD, 29 unaffected children) ages 7-13, who completed the Intolerance of Uncertainty Scale-Short Version (IUS). Responses on the IUS were converted to total IU, prospective IU, and inhibitory IU. A linear mixed model analysis of covariance was conducted while controlling for age, sex, and ADHD medications. A significant interaction was observed between diagnostic status and IU scale. Planned contrasts indicated that children with anxiety disorders and ADHD reported significantly higher levels of IU relative to unaffected children, and children with ADHD reported comparable levels of inhibitory IU relative to children with anxiety disorders. The current results contribute to a growing literature on the link between IU and psychopathology. IU appears to be a transdiagnostic construct present among children with internalizing and externalizing disorders, and may be broadly associated with emotion regulation deficits rather than specific disorder symptoms.

Optimising treatment strategies for ADHD in adolescence to minimise 'lost in transition' to adulthood

The persistence of attention-deficit hyperactivity disorder (ADHD) from adolescence to adulthood is not matched by continuity of care in this transition period. Many adolescents with ADHD have poor medication adherence or even stop medication treatment, and use of behavioural interventions is also suboptimal. The present commentary focuses on treatment strategies that might improve effects of ADHD medication treatment by improving adherence in adolescents with ADHD and/or optimise behavioural interventions for ADHD in adolescence. Most treatment strategies in adolescents with ADHD are merely copied from treatments offered to children. Instead however treatment should be focused on what makes adolescents special and vulnerable, such as poor insight into own functioning and poor decision making. Techniques that offer promise for adolescents are motivational interviewing, use of ecological momentary assessments and interventions, mindfulness-based training and serious games. Systematic studies into the effects of these techniques alone and in combination with medication are lacking.

The relationship between early and late event-related potentials and temperament in adolescents with and without ADHD

Differences in emotional processing are prevalent in adolescents with attention deficit/hyperactivity disorder (ADHD) and are related to clinical impairment, but substantial heterogeneity exists. Within ADHD, some individuals experience difficulty with positive/approach emotions, negative/withdrawal emotions, or both. These problems may reflect differences in emotional reactivity, emotion regulation, or a combination, and the neurophysiological correlates remain unclear. Event-related potentials were collected from 109 adolescents (49 with ADHD) while they completed an emotional go/no-go task with three conditions: happy (positive/approach), fear (negative/withdrawal), and neutral. The P1 and N170 were used as a marker of early emotional processing and the P3b and late positive potential (LPP) were used as markers of later elaborative emotional processing. Emotional response style was assessed with parent and adolescent report on the Early Adolescent Temperament Questionnaire. There were no effects of emotion or group for the P1. Typically-developing adolescents exhibited a larger N170 to emotional vs. neutral faces while adolescents with ADHD showed the opposite pattern. All adolescents exhibited a larger P3b to fearful versus other faces and a larger LPP to emotional vs. non-emotional faces. Within the ADHD group, N170 responses to happy faces predicted parent ratings of positive/approach emotions. Findings highlight the importance of considering within-group heterogeneity when studying clinical populations and help clarify the time-locked neurophysiological correlates of emotion dysregulation.

Anger-irritability as a mediator of attention deficit hyperactivity disorder risk for adolescent alcohol use and the contribution of coping skills

BACKGROUND

Research on susceptibility to alcohol use disorder within the attention deficit/hyperactivity disorder (ADHD) population has begun to expand examination of putative moderators and mediators in order to develop effective treatments. Specific dysregulated emotions have been separately associated with ADHD and with alcohol use difficulties. The current study is the first to conjointly study these variables by testing anger-irritability as a mediator of ADHD risk for adolescent alcohol use.

METHODS

Frequency of binge drinking, drunkenness, and alcohol problems were examined for 142 children with ADHD followed into adolescence and compared to 100 demographically similar youth without ADHD. Parent-rated anger-irritability was tested as a mediator. Behavioral and cognitive coping skills, which are key clinical treatment targets, were studied as moderators of these associations.

RESULTS

Childhood ADHD was positively associated with anger-irritability and the drinking outcomes in adolescence. Anger-irritability mediated the association between ADHD and alcohol use problems, but not binge drinking or drunkenness. Behavioral and cognitive, but not avoidant, coping played a moderating role, but only of the association between childhood ADHD and anger-irritability.

CONCLUSIONS

Active coping strategies by adolescents with ADHD may reduce the vulnerability to alcohol problems through a reduction of negative emotions. Future research on additional mediators and treatments that target these skills is encouraged.

Compliance With Mobile Ecological Momentary Assessment Protocols in Children and Adolescents: A Systematic Review and Meta-Analysis

BACKGROUND

Mobile device-based ecological momentary assessment (mobile-EMA) is increasingly used to collect participants' data in real-time and in context. Although EMA offers methodological advantages, these advantages can be diminished by participant noncompliance. However, evidence on how well participants comply with mobile-EMA protocols and how study design factors associated with participant compliance is limited, especially in the youth literature.

OBJECTIVE

To systematically and meta-analytically examine youth's compliance to mobile-EMA protocols and moderators of participant compliance in clinical and nonclinical settings.

METHODS

Studies using mobile devices to collect EMA data among youth (age ≤18 years old) were identified. A systematic review was conducted to describe the characteristics of mobile-EMA protocols and author-reported factors associated with compliance. Random effects meta-analyses were conducted to estimate the overall compliance across studies and to explore factors associated with differences in youths' compliance.

RESULTS

This review included 42 unique studies that assessed behaviors, subjective experiences, and contextual information. Mobile phones were used as the primary mode of EMA data collection in 48% (20/42) of the reviewed studies. In total, 12% (5/42) of the studies used wearable devices in addition to the EMA data collection platforms. About half of the studies (62%, 24/42) recruited youth from nonclinical settings. Most (98%, 41/42) studies used a time-based sampling protocol. Among these studies, most (95%, 39/41) prompted youth 2-9 times daily, for a study length ranging from 2-42 days. Sampling frequency and study length did not differ between studies with participants from clinical versus nonclinical settings. Most (88%, 36/41) studies with a time-based sampling protocol defined compliance as the proportion of prompts to which participants responded. In these studies, the weighted average compliance rate was 78.3%. The average compliance rates were not different between studies with clinical (76.9%) and nonclinical (79.2%; P=.29) and studies that used only a mobile-EMA platform (77.4%) and mobile platform plus additional wearable devices (73.0%, P=.36). Among clinical studies, the mean compliance rate was significantly lower in studies that prompted participants 2-3 times (73.5%) or 4-5 times (66.9%) compared with studies with a higher sampling frequency (6+ times: 89.3%). Among nonclinical studies, a higher average compliance rate was observed in studies that prompted participants 2-3 times daily (91.7%) compared with those that prompted participants more frequently (4-5 times: 77.4%; 6+ times: 75.0%). The reported compliance rates did not differ by duration of EMA period among studies from either clinical or nonclinical settings.

CONCLUSIONS

The compliance rate among mobile-EMA studies in youth is moderate but suboptimal. Study design may affect protocol compliance differently between clinical and nonclinical participants; including additional wearable devices did not affect participant compliance. A more consistent compliance-related result reporting practices can facilitate understanding and improvement of participant compliance with EMA data collection among youth.

Turning the Page on Pen-and-Paper Questionnaires: Combining Ecological Momentary Assessment and Computer Adaptive Testing to Transform Psychological Assessment in the 21st Century

The current paper describes new opportunities for patient-centred assessment methods which have come about by the increased adoption of affordable smart technologies in biopsychosocial research and medical care. In this commentary, we review modern assessment methods including item response theory (IRT), computer adaptive testing (CAT), and ecological momentary assessment (EMA) and explain how these methods may be combined to improve psychological assessment. We demonstrate both how a 'naïve' selection of a small group of items in an EMA can lead to unacceptably unreliable assessments and how IRT can provide detailed information on the individual information that each item gives thus allowing short form assessments to be selected with acceptable reliability. The combination of CAT and IRT can ensure assessments are precise, efficient, and well targeted to the individual; allowing EMAs to be both brief and accurate.

ADHD and Emotion Dysregulation Among Children and Adolescents

Individuals with attention-deficit/hyperactivity disorder (ADHD) experience impairments in a number of functional domains. Although current evidence-based treatments for ADHD reduce symptoms and improve academic and behavioral functioning, they have minimal impact on social functioning or on risky behaviors (see Evans et al. in J Clin Child Adolesc Psychol, 43:527-551, 2014 for review). Preliminary evidence indicates that emotion dysregulation (ED) is associated with impairments across the developmental spectrum, such as social impairment and risky behaviors, and that its relative absence/presence is differentially associated with treatment response. It thus stands to reason that by incorporating a focus on ED in interventions targeting social impairment and risky behaviors, we may be able to increase the number of youth who respond to such interventions and decrease the prevalence or degree of these impairments and behaviors among youth and adults with ADHD. However, a number of questions remain unaddressed about the association between ADHD and ED, such as the portion of individuals with ADHD who experience ED, the extent to which ED is associated with the above impairments and behaviors, and whether or not ED is malleable. To begin addressing these questions, we summarize and critically evaluate the literature on the association between ADHD and ED and make recommendations for future basic, translational, and treatment outcome research.

Heritability of Intraindividual Mean and Variability of Positive and Negative Affect

Positive affect (e.g., attentiveness) and negative affect (e.g., upset) fluctuate over time. We examined genetic influences on interindividual differences in the day-to-day variability of affect (i.e., ups and downs) and in average affect over the duration of a month. Once a day, 17-year-old twins in the United Kingdom (N = 447) rated their positive and negative affect online. The mean and standard deviation of each individual’s daily ratings across the month were used as the measures of that individual’s average affect and variability of affect. Analyses revealed that the average of negative affect was significantly heritable (.53), but the average of positive affect was not; instead, the latter showed significant shared environmental influences (.42). Fluctuations across the month were significantly heritable for both negative affect (.54) and positive affect (.34). The findings support the two-factor theory of affect, which posits that positive affect is more situational and negative affect is more dispositional.

The Relation of Poor Emotional Awareness and Externalizing Behavior Among Children With ADHD

OBJECTIVE

Children with ADHD often demonstrate poor emotional self-awareness and higher levels of externalizing behavior problems relative to unaffected children. This study examined the relation of deficient emotional self-awareness to externalizing behavior problems in children with ADHD, and the role of emotional reactivity in this relationship.

METHOD

Fifty-one 8- to 12-year-old children with ADHD and their parents completed measures of the children's emotional and behavioral functioning, as well as a diagnostic structured interview.

RESULTS

Logistic regression suggested that more impaired emotional self-awareness was strongly associated with the diagnosis of a comorbid externalizing disorder. Hierarchical regression analyses strongly supported the relation of poor emotional awareness to reactivity-driven externalizing behavior, but not to proactive externalizing behavior. These effects were evident across reporters.

CONCLUSION

This study suggested that poor emotional self-awareness is significantly linked to externalizing problems in children with ADHD, and that dysregulated emotional reactivity plays an important role in this relationship.

Ecological Momentary Assessment and Smartphone Application Intervention in Adolescents with Substance Use and Comorbid Severe Psychiatric Disorders: Study Protocol

CONTEXT

Substance use disorders (SUDs) are highly prevalent among inpatient adolescents with psychiatric disorders. In this population, substance use and other psychiatric outcomes can reinforce one another. Despite the need for integrated interventions in youths with dual diagnoses, few specific instruments are available. App-based technologies have shown promising results to help reduce substance use in adolescents, but their applicability in youths with associated severe psychiatric disorders is poorly documented. We aim to evaluate the feasibility of an ecological momentary assessment (EMA) intervention for all substance users, and of a smartphone application for cannabis users (Stop-Cannabis), for outpatient treatment after hospital discharge.

METHODS AND ANALYSIS

All inpatient adolescents with psychiatric disorders hospitalized between 2016 and 2018 in a university hospital will be systematically screened for SUD and, if positive, will be assessed by an independent specialist addiction team. Participants with confirmed SUDs will be invited and helped to download an EMA app and, if required, the Stop-Cannabis app, the week preceding hospital discharge. Information about the acceptability and use of both apps and the validity of EMA data in comparison to clinical assessments will be assessed after 6 months and 1 year.

DISCUSSION

This research has been designed to raise specific issues for consideration regarding the sequence between substance use, contextual factors, and other psychiatric symptoms among adolescents with comorbid severe psychiatric disorders. A better understanding of the mechanisms involved will inform the development of integrated treatment for dual disorders at that age.

ETHICS AND DISSEMINATION

The study has already been approved and granted. Dissemination will include presentations at international congresses as well as publications in peer-reviewed journals.
