The Proposed Specifiers for Conduct Disorder (PSCD) Scale: Factor Structure and Validation of the Self-Report Version in a Forensic Sample of Belgian Youth

Psychopathy and Impairments in Emotion Regulation: A systematic review and Meta-analysis

Considering the sparse but rapidly growing literature concerning the relationship between psychopathy and emotion regulation, taking stock of accumulating knowledge in a systematic review and meta-analysis of the existing results is needed. We performed a systematic search (up to May 30, 2024) following PRISMA guidelines of five scientific databases (PsycINFO, PsycARTICLES, MEDLINE, PubMed, Scopus and Web of Science). Also, gray literature was searched. After removing the duplicates, a total of 8.786 records were screened, and 73 articles were selected based on the inclusion criteria used for systematic review. The meta-analytic procedure was performed on 55 identified studies consistent with the criteria adopted, which overall comprised 29.856 individuals. The current systematic and meta-analysis review has clarified the association between impairments of emotional regulation abilities and facets of psychopathy. More specifically, analyses indicated that emotional dysregulation is associated with overall levels of psychopathic traits, as well as with both the lifestyle and affective components of psychopathy, which suggests the utility of assessing these features when designing interventions focused on modulating negative emotional states and enhancing regulation of impulsive behaviors.

The Prognostic Usefulness of Multiple Specifiers for Subtyping Conduct Problems in Early Childhood

OBJECTIVE

To better describe and treat children with conduct problems (CP), grandiose-manipulative and daring-impulsive traits are proposed for subtyping CP, instead of using only a callous-unemotional specifier. However, the acclaimed benefits of having multiple specifiers for CP remain largely untested and therefore highly speculative. To fill this gap, this study tested longitudinal relations between these 3 specifiers and developmental outcomes in childhood and adolescence, independent of early childhood CP.

METHOD

Longitudinal data from 2 community studies were used. Teacher ratings were used to measure CP and the specifiers in 3- to 5-year-olds from Sweden (n = 2,064) and Spain (n = 2,055). Developmental outcomes were assessed by multiple informants (ie, teachers, parents, and children) 1 to 8 years later.

RESULTS

Early childhood CP were predictive of all outcomes. Callous-unemotional traits predicted low levels of social competence and prosocial behavior, independent of CP (and age, sex, and socioeconomic status). Grandiose-manipulative and daring-impulsive traits were predictive of aggression and violent delinquency, respectively, independent of CP, but also of higher levels of prosocial behavior or social competence.

CONCLUSION

The 3 specifiers are predictive of different outcomes, independent of CP, which is thought to form the basis for developing specifiers for CP. Findings tentatively challenge the centrality of callous-unemotional traits for subtyping CP, but it is premature to conclude that grandiose-manipulative and daring-impulsive specifiers are needed in future revisions of DSM and ICD. Efforts to systematically evaluate the utility of these specifiers should be welcomed to inform ongoing debates on this matter.

Proposed Specifiers for Conduct Disorder (PSCD) scale: A Latent Profile Analysis with At-Risk Adolescents

The Proposed Specifiers for Conduct Disorder (PSCD; Salekin in Pers Disord: Theory Res Treat 7:180-191, 2016) scale was designed to assess interrelated psychopathic trait domains in conjunction with symptoms of Conduct Disorder (CD) in children and adolescents (i.e., grandiose-manipulative, callous-unemotional, daring-impulsive). Variable-centered studies have provided support for a four-factor PSCD structure (Salekin et al. in Psychol Assess 34(10):985-992, 2022) in line with other adolescent and adult studies. The current person-centered study used latent profile analysis of the PSCD domains to examine whether theoretically meaningful and empirically robust PSCD subtypes emerged from a diverse sample (70.9% White, 20.1% Black, 3.6% Hispanic, and 5.4% other) of adolescents (modal age = 17) in a military style residential facility (N = 409; Males = 80.6%). As hypothesized, a four-class solution was best, consistent with adult psychopathy subtyping research (Hare et al. in Handbook of Psychopathy 39-79, 2018; Roy et al. in Pers Disord: Theory Res Treat, in press). The PSCD subtype profiles were uniform across sex and race/ethnicity. Adolescents evincing a psychopathic trait propensity profile (elevated on all four PSCD domains) displayed the greatest number of arrests and higher overall externalizing psychopathology, compared to the other three latent classes, as well as higher internalizing psychopathology compared to adolescents with general delinquency. The PSCD provides a sound measure of psychopathic trait propensities in youth and our results offer investigators and clinicians a means for understanding person-centered psychopathic traits versus antisocial profiles among at-risk adolescents. Taken together, the current results may offer a viable approach for examining specific treatment targets based on PSCD subtype profiles.

Proposed Specifiers for Conduct Disorder (PSCD) self-report: Factor structure and validation in a community sample of Belgian youth

The current study examined the psychometric properties of the Proposed Specifiers for Conduct Disorder (PSCD) in a sample of school-attending adolescent Belgian youth (N = 599; M age = 16.51 years, SD = 1.27). Given the recent interest in the PSCD-Short Version (PSCD-SV), this study focused on the 13-item variant of the PSCD. Study findings showed that the PSCD-SV had a hierarchical four-factor structure including the components of grandiose-manipulative (GM), callous-unemotional (CU), daring-impulsive (DI), and conduct disorder (CD). These interrelated factors were found to be internally consistent. The study also showed that the PSCD-SV total score was positively and significantly related to an alternate measure of psychopathy. Further, the study revealed the PSCD-SV was meaningfully related to the five-factor personality domains (i.e., extraversion, conscientiousness, agreeableness) as well as peer functioning and prosocial behavior. Bivariate correlations demonstrated that the dimensions differed in their associations with external correlates (e.g., peer functioning). Regression analyses showed that the GM, CU, and CD components of the PSCD-SV were uniquely associated to externalizing difficulties, whereas only the GM and CU components of the PSCD-SV were associated with low prosocial behaviors. These findings shed light on the conceptual and developmental models for the consideration of psychopathy and conduct problems. The use of the broader psychopathy condition as well as its underpinning dimensions may have important implications for assessment, treatment, and diagnostic manuals. The implications of the current study are further discussed.

The Proposed Specifiers for Conduct Disorder (PSCD) in Iranian School-Attending Adolescents: A Multi-Informant Validation Study of the PSCD Parent- and Youth Self-Report Versions

The Proposed Specifier for Conduct Disorder (PSCD) was developed to measure the broad psychopathy construct with grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder subscales. This study tested the psychometric properties of Persian parent-and-child self-report PSCD versions with 974 parents (86% mothers) and children/adolescents (46.5% boys) dyads. Results showed that with some modifications the proposed hierarchical four-factor structure for both PSCDs was confirmed and was found to be invariant across gender. Across versions, all PSCD scores were internally consistent and demonstrated expected correlations with parent-reported externalizing problems, anxiety/depression, and poor school performance, supporting the PSCDs scores' validity. This study also is the first to examine and establish acceptable to excellent parent-child agreement of PSCD scores. Finally, all PSCD child-report scores offered small though significant incremental validity over their corresponding PSCD parent-version scores in predicting parent-reported conduct problems and proactive aggression. Findings indicated that both Persian PSCDs may hold promise for assessing psychopathy components in Iranian school-attending adolescents and generating additional research on this topic.

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

The assessment of oppositional defiant disorder, conduct disorder, antisocial personality disorder, and intermittent explosive disorder-the Disruptive, Impulse Control and Conduct Disorders-can be affected by biases in clinical judgment, including overestimating concerns about distinguishing symptoms from normative behavior and stigma associated with diagnosing antisocial behavior. Recent nosological changes call for special attention during assessment to symptom dimensions of limited prosocial emotions and chronic irritability. The present review summarizes best practices for evidence-based assessment of these disorders and discusses tools to identify their symptoms. Despite the focus on disruptive behavior disorders, their high degree of overlap with disruptive mood dysregulation disorder can complicate assessment. Thus, the latter disorder is also included for discussion here. Good practice in the assessment of disruptive behavior disorders involves using several means of information gathering (e.g., clinical interview, standardized rating scales or checklists), ideally via multiple informants (e.g., parent-, teacher-, and self-report). A commitment to providing a full and accurate diagnostic assessment, with careful and attentive reference to diagnostic guidelines, will mitigate concerns regarding biases.

Contemporary diagnosis and treatment of conduct disorder in youth

INTRODUCTION

Conduct disorder (CD) is characterized by repetitive and persistent antisocial behaviors, being among the most frequently reported reasons of referral in youth. CD is a highly heterogeneous disorder, with possible specifiers defined according to age at onset, Limited Prosocial Emotions (LPE) otherwise known as Callous-Unemotional (CU) traits, Emotional Dysregulation (ED), and patterns of comorbidity, each with its own specific developmental trajectories.

AREAS COVERED

The authors review the evidence from published literature on the clinical presentations, diagnostic procedures, psychotherapeutic and psychoeducational approaches, and pharmacological interventions from RCT and naturalistic studies in youth. Evidence from studies including youths with LPE/CU traits, ED and aggression are also reviewed, as response moderators.

EXPERT OPINION

Due to its clinical heterogeneity, relevant subtypes of CD should be carefully characterized to gain reliable information on prognosis and treatments. Thus, disentangling this broad category in subtypes is crucial as a first step in diagnosis. Psychosocial interventions are the first option, possibly improving LPE/CU traits and ED, especially if implemented early during development. Instead, limited information, based on low-quality studies, supports pharmacological options. Second-generation antipsychotics, mood stabilizers, and stimulants are first-line medications, according to different target symptoms, such as aggression and emotional reactivity. Developmental pathways including ADHD suggest a specific role of psychostimulants.

Psychopathic Traits, Externalizing Problems, and Prosocial Behavior: The Role of Social Dominance Orientation

Psychopathic traits in community and referred youths are strongly associated with severe externalizing problems and low prosocial behavior. However, less is known about the mechanisms that may link youth psychopathy and these outcomes. Social dominance orientation (SDO), defined as the general individual orientation toward unequal and dominant/subordinate relationships, might represent a valuable construct to explore to better understand the association between psychopathic traits, externalizing problems, and prosocial behavior. Based on this, the current study aimed to investigate the relationship between psychopathic traits, SDO, externalizing problems, and prosocial behavior in a community sample (N = 92, 45.57% females, mean age = 12.53, and SD = 0.60) and in a clinical (N = 29, 9% female, mean age = 12.57, and SD = 0.57) samples of adolescents with Oppositional Defiant Disorder or Conduct Disorder. Results showed that SDO mediated the relationship between psychopathic traits and externalizing problems and between psychopathic traits and prosocial behavior only in the clinical sample. These findings can provide valuable information on psychopathic trait correlates in youths with aggressive behavior disorders; treatment implications are discussed.

The Proposed Specifiers for Conduct Disorder - Parent (PSCD-P): Convergent Validity, Incremental Validity, and Reactions to Unfamiliar Peer Confederates

Youth who experience psychopathy display multiple impairments across interpersonal (grandiose-manipulative [GM]), affective (callous-unemotional [CU]), lifestyle (daring-impulsive [DI]), and potentially antisocial and behavioral features. Recently, it has been acknowledged that the inclusion of psychopathic features can offer valuable information in relation to the etiology of Conduct Disorder (CD). Yet, prior work largely focuses on the affective component of psychopathy, namely CU. This focus creates uncertainty in the literature on the incremental value of a multicomponent approach to understanding CD-linked domains. Consequently, researchers developed the Proposed Specifiers for Conduct Disorder (PSCD; Salekin & Hare, 2016) as a multicomponent approach to assess GM, CU, and DI features in combination with CD symptoms. The notion of considering the wider set of psychopathic features for CD specification requires testing whether multiple personality dimensions predict domain-relevant criterion outcomes above-and-beyond a CU-based approach. Thus, we tested the psychometric properties of parents' reports on the PSCD (PSCD-P) in a mixed clinical/community sample of 134 adolescents (M_age = 14.49, 66.4% female). Confirmatory factor analyses resulted in a 19-item PSCD-P displaying acceptable reliability estimates and a bifactor solution consisting of GM, CU, DI, and CD factors. Findings supported the incremental validity of scores taken from the PSCD-P across multiple criterion variables, including (a) an established survey measure of parent-adolescent conflict; and (b) trained independent observers' ratings of adolescents' behavioral reactions to laboratory controlled tasks designed to simulate social interactions with unfamiliar peers. These findings have important implications for future research on the PSCD and links to adolescents' interpersonal functioning.

The Relative Importance of Psychopathy Features as Predictors of Externalizing Behaviors in Youth: A Multimethod Examination

Research in youth psychopathy has focused heavily on the affective features (i.e., callous-unemotional [CU] traits) given robust links to severe and chronic forms of externalizing behaviors. Recently, there have been calls to expand the scope of work in this area to examine the importance of other interpersonal (i.e., antagonism) and behavioral (i.e., disinhibition) features of psychopathy. In the present study, we apply an under-utilized statistical approach (i.e., dominance analysis) to assess the relative importance of CU traits, antagonism, and disinhibition in the prediction of externalizing behaviors in youth, cross-sectionally and at 9-month follow-up. Using a multi-informant (youth- and parent-report), multi-method (questionnaire, ecological momentary assessment [EMA]) preregistered approach in a diverse sample of clinically referred youth (Mage = 12.60 years, SD = .95 years, 47% female; 61% racial/ethnic minority), we found youth- and parent-reported psychopathy features accounted for a significant proportion of variance in externalizing behavior cross-sectionally and longitudinally. However, results provided limited support for our preregistered hypotheses. While antagonism and disinhibition had larger general dominance weights relative to CU traits for both youth- and parent-report, most differences were non-significant. Thus, the interpersonal, affective, and behavioral psychopathy features could not be distinguished from one another in terms of their importance in the prediction of externalizing behavior, assessed cross-sectionally or longitudinally. Taken together, the results highlight promising avenues for future research on the relative importance of youth psychopathy features.

Validation of the Proposed Specifiers for Conduct Disorder (PSCD) Self-Report Version in Iranian School-Attending Adolescents

The Proposed Specifiers for Conduct Disorder (PSCD) scale was developed to advance the study of child and adolescent psychopathy, especially as it relates to conduct disorder. This study is the first to test the factor structure, measurement invariance, internal consistency, and validity of the Persian PSCD self-report version in a gender-mixed sample of 1,506 school-attending 11 to 18 years old youth (M age = 15.23; SD = 1.83; 49.60% boys). Confirmatory factor analysis supported the proposed four-factor hierarchical structure of the PSCD, though with 19 items loaded on grandiose-manipulative, callous-unemotional, daring-impulsive, and conduct disorder components. This factor structure was also invariant across gender. The PSCD total and four components scores were internally consistent and exhibited the expected relations with proactive aggression, externalizing problems, anxiety and depression, and poor school performance, supporting the PSCD scores' convergent, discriminant, and criteria validity. The findings indicated that with some modifications, the Persian PSCD might hold promise for assessing psychopathy components in Iranian school-attending adolescents and may spark additional research in a variety of settings.
