Evidence-Based Assessment of DSM-5 Disruptive, Impulse Control, and Conduct Disorders

Within-person Relations Between Social Skills and Symptoms of Oppositional Defiant Disorder and Conduct Disorder from Preschool to Adolescence - A Birth Cohort Study

Effective treatment of oppositional defiant disorder (ODD) and conduct disorder (CD) is dependent on etiological knowledge about what factors contribute to their development and maintenance. Previous research points to a role for social skills in this process, but findings are mixed, possibly due to methodological factors. A sample drawn from two birth cohorts (n = 1,079, 50.1% girls) in the city of Trondheim, Norway, was assessed biennially from age 4 to 16 years. Social skills were rated by teachers and parents and measures of symptoms of ODD and CD were obtained through diagnostic interviews of parents and children (from age 8). Bidirectional relations between within-person changes in social skills and symptoms of ODD and CD, respectively, were assessed by a random intercept cross-lagged model. Increased parent-reported social skills predicted reduced symptoms of both ODD and CD from preschool to adolescence, while teacher-rated social skills predicted reduced symptoms of ODD from 4 to 14 years but predicted reduced symptoms of CD from 6 to 8 years only. Symptoms of ODD and CD predicted reduced teacher-rated social skills on two occasions (6 to 8 years for CD and 8 to 10 years for ODD), but there were no reciprocal paths involving parent-rated social skills. Findings provide support for including social skills training in the prevention and treatment of symptoms of ODD and CD.

Effects of Patient Gender on Clinicians' Diagnostic Assessment of Youth Disruptive Mood and Behavior

OBJECTIVE

Youth disruptive behavior disorders (DBDs) have a male preponderance, but the extent to which gender biases in clinical assessment influence this imbalance remains unclear. The present study investigates whether a child patient's gender affects clinicians' diagnostic decision-making regarding Oppositional Defiant Disorder (ODD), Conduct Dissocial Disorder (CDD), and Intermittent Explosive Disorder (IED).

METHOD

Clinicians (N = 403; 57.1% male; Mage = 48.96 years, SD = 11.09) participated in a global ICD-11 field study. Following an experimental design, participants were asked to use ICD-10 or ICD-11 diagnostic guidelines to evaluate two clinical case vignettes, randomly manipulating the patients' gender (boy, girl) and symptom presentation (ODD-Defiant, ODD-Irritable, CDD, IED). Analyses tested whether clinicians' diagnostic accuracy and perceptions of impairment and severity were affected by the patient's gender.

RESULTS

Overall, clinicians identified the correct diagnosis 64.7% of the time. Patient gender was not associated with clinicians' diagnostic accuracy (ps= .090-.895, |φs| = 0.01-0.18) or severity or impairment ratings (ps = .079-.404, |ds| = 0.04-0.19). This pattern of nonsignificant differences and negligible/small effect sizes was consistent across all clinical presentations and analyses.

CONCLUSIONS

We found no evidence of an association between patient gender, diagnostic accuracy, or perceived severity or impairment when assessing youth DBDs in the present study. Results suggest that diagnostic judgments may be driven by clinical presentation rather than gender and that the male DBD preponderance may not be due to gender diagnostic biases. Further research is needed to replicate these findings among youths in clinical settings, with diverse gender identities, and with other mental health conditions.

Evidence Base Update on the Assessment of Irritability, Anger, and Aggression in Youth

OBJECTIVE

Irritability, anger, and aggression have garnered significant attention from youth mental health researchers and clinicians; however, fundamental challenges of conceptualization and measurement persist. This article reviews the evidence base for assessing these transdiagnostic constructs in children and adolescents.

METHOD

We conducted a preregistered systematic review of the evidence behind instruments used to measure irritability, anger, aggression, and related problems in youth. Searches were conducted in PsycINFO and PubMed, identifying 4,664 unique articles. Eligibility criteria focused on self- and proxy-report measures with peer-reviewed psychometric evidence from studies in English with youths ages 3-18. Additional measures were found through ancillary search strategies (e.g. book chapters, review articles, test publishers). Measures were screened and coded by multiple raters with acceptable reliability.

RESULTS

Overall, 68 instruments met criteria for inclusion, with scales covering irritability (n = 15), anger (n = 19), aggression (n = 45), and/or general overt externalizing problems (n = 27). Regarding overall psychometric support, 6 measures (8.8%) were classified as Excellent, 46 (67.6%) were Good, and 16 (23.5%) were Adequate. Descriptive information (e.g. informants, scales, availability, translations) and psychometric properties (e.g. reliability, validity, norms) are summarized.

CONCLUSIONS

Numerous instruments for youth irritability, anger, and aggression exist with varying degrees of empirical support for specific applications. Although some measures were especially strong, none had uniformly excellent properties across all dimensions, signaling the need for further research in particular areas. Findings promote conceptual clarity while also producing a well-characterized toolkit for researchers and clinicians addressing transdiagnostic problems affecting youth.

The Affective Side of Disruptive Behavior: Toward Better Understanding, Assessment, and Treatment

Historically, much of the progress made in youth mental health research can be classified as focusing on externalizing problems, characterized by disruptive behavior (e.g. aggression, defiance), or internalizing problems, characterized by intense negative affect (e.g. depression, anxiety). Until recently, however, less attention has been given to topics that lie somewhere in between these domains, topics that we collectively refer to as the affective side of disruptive behavior. Like the far side of the moon, the affective side of disruptive behavior captures facets of the phenomenon that may be less obvious or commonly overlooked, but are nonetheless critical to understand. This affective side clarifies socially disruptive aspects of traditionally "externalizing" behavior by elucidating proximal causation via intense negative affect (traditionally "internalizing"). Such problems include irritability, frustration, anger, temper loss, emotional outbursts, and reactive aggression. Given a recent explosion of research in these areas, efforts toward integration are now needed. This special issue was developed to help address this need. Beyond the present introductory article, this collection includes 4 empirical articles on developmental psychopathology topics, 4 empirical articles on applied treatment/assessment topics, 1 evidence base update review article on measurement, and 2 future directions review articles concerning outbursts, mood, dispositions, and youth psychopathology more broadly. By deliberatively investigating the affective side of disruptive behavior, we hope these articles will help bring about better understanding, assessment, and treatment of these challenging problems, for the benefit of youth and families.
