Comprehensive Psychometric Analysis of the Eyberg Child Behavior Inventory in Children with Autism Spectrum Disorder

Predictors of Aggression, Disruptive Behavior, and Anger Dysregulation in Youths with Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) often experience difficulties related to aggression, disruptive behavior, and regulation of emotions that precipitate these behaviors (i.e., anger). The extent to which aggression, disruptive behaviors, and anger dysregulation are correlated with distinct or overlapping factors has not yet been explored. The present study examined whether aspects of participant demographics, individual youth functioning, caregiver stress, and family warmth contributed to youth aggression, disruptive behavior, and anger dysregulation. Participants were caregivers of 511 youths with ASD. Analyses revealed that significant proportions of variance in aggression, disruptive behaviors, and anger dysregulation were accounted for by shared variables pertaining to demographics, the individual youth, and caregiver stress. Implications of treatment and future research are discussed.

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.

Community-based Agency Delivery of Parent-Child Interaction Therapy: Comparing Outcomes for Children with and Without Autism Spectrum Disorder and/or Developmental Delays

While externalizing behaviors are common among children with autism spectrum disorder (ASD), there is a shortage of specialist community-based clinicians to provide treatment. Parent-Child Interaction Therapy (PCIT), an intervention designed to reduce child disruptive behaviors, may be effective for families of children with ASD but has rarely been studied outside of university-based research settings. We examined the effectiveness of PCIT delivered for children with (N = 109) and without (N = 2,324) ASD/developmental delays (DD) across community-based agencies in Oregon. Findings revealed significant reductions in disruptive behavior and positive changes in the parent-child relationship in both groups. These findings support PCIT as an efficacious intervention for children with ASD/DD and demonstrate PCIT's promise in community-based agencies with non-specialized clinicians.

Behavioral Parent Training Engagement Among Young Children With Autism Spectrum Disorder

The purpose of the current study was to examine engagement with Behavioral Parent Training (BPT) for families of children with Autism Spectrum Disorder (ASD) and assess openness to novel delivery formats for BPT (e.g., telehealth, group). Participants were caregivers of 501 children with ASD (ages 2-6) enrolled in the SPARK (Simons Foundation Powering Autism Research for Knowledge) online national registry. The study assessed: (1) rates of child disruptive behavior diagnoses, (2) engagement and satisfaction with BPT, (3) parent and child factors (e.g., diagnostic history), and (4) openness to novel delivery formats. Almost 25% of young children with ASD in this sample had disruptive behavior problems rising to the level of a diagnosis of ADHD or ODD and thus would benefit from BPT. However, only one third of these families had actually been referred to BPT. Families indicated high level of interest in participating in BPT, with a particular interest in Parent Child Interaction Therapy (PCIT) as well as novel delivery formats such as telehealth and group. Specific components of the therapy and delivery formats were indicative of parent satisfaction (e.g. groups, longer treatment sessions, longer treatment length). Specific parent and child characteristics were predictive of openness to novel formats (e.g. parental depression, more severe behavioral challenges, lower verbal skills). Results underscore the need for increased referrals and access to BPT programs the ASD population. Both parent and child characteristics are important for determining appropriate delivery formats.

Psychometric Assessment of the Eyberg Child Behavior Inventory in Children with Autism in Community Settings

The Eyberg Child Behavior Inventory (ECBI) is a frequently used measure to assess interfering behaviors in children and psychometric properties have recently been examined in children with autism spectrum disorder (ASD). There is a need to confirm the identified factors and examine the factor structure in a racially/ethnically diverse, community-based sample. The current study conducts a psychometric analysis of the ECBI in a sample of children with ASD receiving publicly-funded mental health services. Data were collected from 201 children with ASD ages 5-13 years (60% Hispanic/Latinx) participating in a community effectiveness trial. Confirmatory factor analysis indicated poor model fit using previously identified factors and a new four-factor solution was identified. Clinical and research implications of these findings are discussed.

Parent-Child Interaction Therapy for Children with Disruptive Behaviors and Autism: A Randomized Clinical Trial

A relatively large number of children with autism spectrum disorder (ASD) exhibit disruptive behavioral problems. While accumulating data have shown behavioral parent training programs to be efficacious in reducing disruptive behaviors for this population, there is a dearth of literature examining the impact of such programs across the range of ASD severity. To evaluate the effectiveness of Parent-Child Interaction Therapy (PCIT), an evidence-based treatment for children with problem behaviors and their families, in reducing disruptive behaviors among children (4-10 years) with ASD (without intellectual disabilities). Fifty-five children (85.5% male, 7.15 years; SD 1.72) were enrolled from pediatric offices and educational settings into a randomized clinical trial (PCIT: N = 30; Control: N = 25). PCIT families demonstrated a significant reduction in child disruptive behaviors, increase in positive parent-child communication, improvement in child compliance, and reduction in parental stress compared to the control group. Exploratory analyses revealed no differential treatment response based on ASD severity, receptive language, and age. Results are promising for the use of PCIT with children demonstrating disruptive behaviors across the autism spectrum.

Training Community Therapists in AIM HI: Individual Family and Neighborhood Factors and Child/Caregiver Outcomes

OBJECTIVE

Publicly funded mental health services play an important role in caring for children with mental health needs, including children with autism spectrum disorder (ASD). This study assessed the associations between individual family- and neighborhood-level sociodemographic factors and baseline family functioning and long-term outcomes when community therapists were trained to deliver An Individualized Mental Health Intervention for ASD (AIM HI).

METHOD

Participants included 144 children with ASD (ages 5 to 13 years; 58.3% Latinx) and their caregivers whose therapists received AIM HI training within a cluster-randomized effectiveness-implementation trial in publicly funded mental health services. Sociodemographic strain (e.g., low income, less education, single-parent status, minoritized status) was coded at the individual family and neighborhood level, and caregivers rated caregiver strain at baseline. Child interfering behaviors and caregiver sense of competence were assessed at baseline and 6-, 12- and 18-months after baseline.

RESULTS

Higher caregiver strain was associated with higher intensity of child behaviors (B = 5.17, p < .001) and lower caregiver sense of competence (B = -6.59, p < 001) at baseline. Child and caregiver outcomes improved over time. Higher caregiver strain (B = 1.50, p < .001) and lower family sociodemographic strain (B = -0.58, p < .01) were associated with less improvements in child behaviors. Lower caregiver strain (B = -2.08, p < .001) and lower neighborhood sociodemographic strain (B = -0.51, p < .01) were associated with greater improvements in caregiver sense of competence.

CONCLUSIONS

Findings corroborate the importance of considering both family and neighborhood context in the community delivery of child-focused EBIs.

Psychotropic Medication Use by Children with Autism Served in Publicly Funded Mental Health Settings

OBJECTIVE

The aim of this study was to characterize patterns of and factors associated with psychotropic medication use in children with autism spectrum disorder (ASD) receiving publicly funded mental health services.

METHOD

Data were extracted from 202 children with ASD participating in a cluster randomized trial of An Individualized Mental Health Intervention for ASD conducted in 29 publicly funded mental health programs. Children with ASD were aged 5 to 13 years (M = 9.1 years, SD = 2.4), and were 84.2% male and 59.9% Latinx. Child ASD and cognitive functioning were determined by standardized assessment. Caregivers reported child psychotropic medication use, behavior problems, ASD symptom severity, mental health symptoms, family demographics, and caregiver strain at the baseline.

RESULTS

Nearly half (49.5%) of participants used psychotropic medication(s) within the past 6 months, with stimulants being most commonly reported. Child co-occurring attention-deficit/hyperactivity disorder (ADHD) (B = 1.55, p < 0.01; 95% confidence interval [CI]: 0.53-2.57), lower cognitive functioning (B = -0.03, p = 0.02; 95% CI: -0.05 to <0.00), and non-Hispanic White ethnicity (vs Hispanic/Latinx; B = 1.02, p = 02; 95% CI: -1.89 to -0.14) were associated with a greater likelihood of using any type of medication. Factors associated with medication use varied by class: stimulants-ADHD, lower ASD symptom severity, and more intensive behavior problems; SSRIs-higher ASD symptom severity; alpha-2 agonists-ADHD, higher ASD symptom severity, lower cognitive functioning, and higher caregiver strain; and antipsychotics-none.

CONCLUSION

The findings highlight factors associated with psychotropic medication use for a clinically complex population, which may inform community care improvement efforts.

Comparative Effectiveness of Parent-Child Interaction Therapy for Children with and Without Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) often display disruptive behavior and noncompliance. Disruptive behavior in youth with ASD may limit their participation in educational and therapeutic activities and impact family functioning. Several evidence-based interventions are available for typically developing children, such as Parent-Child Interaction Therapy (PCIT). The current study examined the comparative effectiveness of PCIT for youth with ASD and without ASD. Results indicate that PCIT significantly improves parent-reported disruptive behavior in children with ASD at levels comparable to children without ASD. Additionally, improvements in ASD-related symptoms were noted for youth with ASD. These findings support the use of PCIT for children with ASD and provide clinicians with an evidence-based tool to address disruptive behavior in a wide spectrum of presenting children.

Psychiatric assessment

Studies have consistently reported an increased prevalence of psychiatric comorbidity (PC) in individuals with neurodevelopmental disorders (NDDs) compared with typically developing controls, with high rates of anxiety disorders in autism spectrum disorders and challenging behaviors in children and adolescent with intellectual disability. Psychiatric assessment in this population should include multiple sources of information, derived from multiple contexts and using multiple methods, with accurate detection of contributing and trigger factors. It is important to focus on detecting change from the child's baseline functioning and to use, when possible, ad hoc instruments for assessing PC in the NDD population. Modifications in the setting and assessment procedures should be scheduled based on the child's age, developmental level, and sensory sensitivities. Simultaneously, validated screening instruments, which dimensionally assess the symptomatology of several NDDs and psychiatric disorders, are warranted to not only assist in the identification of PCs in NDDs but also discriminate among different NDDs. Changes from DSM-IV-TR to DSM-5 have had an impact on the diagnosis of several disorders in children and adolescents and, subsequently, on the current diagnostic tools, requiring appropriate and prompt modifications of the available instruments.

A Case Study of Parent–Child Interaction Therapy for the Treatment of High-Functioning Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) may have difficulties with compliance, impulsivity, and attention, which can affect daily adaptive functioning leading to disruptions in family social interactions, communication skills, academic achievement, and engagement in the community. Although previous research has identified behavioral treatments such as applied behavior analysis (ABA) therapy for youth with ASD, it is important to explore more interventions that can be effective in decreasing problematic behaviors while also building positive social skill development. This case study illustrates the effectiveness of Parent–Child Interaction Therapy (PCIT) to address behavioral problems in a 7-year-old boy with high-functioning ASD (HF-ASD) and comorbid ADHD. Overall, the results demonstrated a decrease in child challenging behaviors and an increase in child compliance. In addition, the child’s mother increased her use of positive parenting skills and effective commands. This study provides additional support for PCIT for children with ASD, but was not without challenges. These challenges, characteristic of families affected by ASD, and treatment implications for clinicians working with this population are discussed.
