Training Community Therapists to Deliver an Individualized Mental Health Intervention for Autism Spectrum Disorder: Changes in Caregiver Outcomes and Mediating Role on Child Outcomes

Randomized Feasibility Pilot of an Executive Functioning Intervention Adapted for Children's Mental Health Settings

The critical role of executive functioning in autism as well as the co-occurring mental health challenges common among autistic youth support to the immense value of interventions targeting executive functioning for enhancing mental health services for autistic children. The goal of the present study was to conduct a randomized feasibility trial of Unstuck and On Target, an executive functioning intervention, adapted for delivery in children's community mental health setting. Mental health therapists (n = 26) enrolled with participating autistic clients (n = 32) were randomized to receive training in and deliver the adapted Unstuck intervention or to deliver care as usual. We completed masked observational measures of Unstuck strategy use (fidelity) during recorded sessions of participating therapist-client dyads and collected measures of acceptability from participating clients and their caregivers. We also collected measures of pre-post changes in executive functioning and mental health symptoms. Therapists trained in Unstuck demonstrated significantly higher use of Unstuck strategies compared to usual care therapists. Caregivers and autistic clients perceive adapted Unstuck as highly acceptability and helpful. Autistic clients whose therapists were trained in adapted Unstuck demonstrated larger pre-post changes in executive functioning compared to usual care. Across all participating clients, changes in executive functioning were significantly related to changes in mental health symptoms. Finally, clients of therapists trained in adapted Unstuck demonstrated moderate improvements in overall mental health symptoms. The current study provides preliminary evidence of the feasibility and impact of Unstuck and On Target for children's community mental health settings.

Treatment mechanism of the WHO caregiver skills training intervention for autism delivered in community settings

This study examined the mechanism of effect of the WHO Caregiver Skills Training (CST) through secondary analysis of a pilot RCT conducted in community settings. Participants were 86 caregivers (77% mothers) of children with ASD (78% male, mean age: 44.8 months) randomized to CST (n = 43) or treatment as usual (n = 43). The primary outcomes, measured at baseline (t1), immediately post-intervention (t2), and 3 months post-intervention (t3), were derived from the coding of caregiver-child free play interactions with the Brief Observation of Social-Communication Change (BOSCC) and the Joint Engagement Rating Inventory scale (JERI). At t3 positive treatment main effects had been observed for caregiver skills supportive of the interaction and for flow of the interaction (JERI), albeit only non-significant changes in the expected direction for child outcomes: autism phenotypic behaviors (BOSCC), joint engagement and availability to interact (JERI). This study tested the theory of change of CST, hypothesizing that the intervention would lead to an improvement on all child and dyad outcomes through an increase in the caregiver skills supportive of the interaction. Serial mediation analyses revealed that the effect of the intervention was significantly influenced by change in caregiver skills. Participation in the intervention led to notable increases in caregiver skills at t2 and t3, which subsequently contributed to improvements at t3 in flow of the interaction, autism phenotypic behavior, joint engagement, and availability to interact. We confirmed our a priori hypothesis showing that change in caregiver skills significantly mediated the effect of treatment on the dyad primary outcome, as well as on the other child outcomes that had shown non-significant changes in the expected direction. Implications for intervention design and policy making in the context of public health services are discussed.

Examining adaptations necessary to support the implementation of a parent-mediated intervention for children with autism spectrum disorder and moderate feeding problems

LAY ABSTRACT

Moderate feeding problems and disruptive mealtime behaviors are common in children with autism spectrum disorder. Although parent-mediated interventions are able to support feeding problems in autistic children, most research has occurred within specialty clinics when delivered by highly trained clinicians. Thus, the fit of these interventions within community settings is not clear. To address this limitation, this study explored adaptations to a parent-mediated intervention, Managing Eating Aversions and Limited Variety (i.e. MEAL Plan), to improve its fit and use within community settings. Participants were 14 multidisciplinary providers who attended one of the three intensive workgroups that included focus groups about the fit of MEAL Plan in their practice setting. Qualitative analysis was used to determine the main themes that came up within the focus groups. Specific themes included the appropriateness MEAL Plan for autistic and non-autistic children, how providers might adapt their delivery of MEAL Plan, billing and insurance considerations, administrator support for MEAL Plan, and the content and format of ongoing training and consultation. By proactively considering and responding to these factors, it may be possible to enhance MEAL Plan so that it is better able to be delivered and sustained within community practices that support autistic children.

Effects of a Parenting Intervention for Emotional and Behavioral Problems in Young Autistic Children Under Conditions of Enhanced Uncertainty: Two-Year Follow-up of a Pilot Randomized Controlled Trial Cohort (ASTAR) During the United Kingdom COVID-19 Pandemic

OBJECTIVE

Most young autistic children display emotional and behavioral problems (EBPs). There is evidence that behavioral parenting interventions (BPIs) reduce these. The COVID-19 pandemic and associated lockdowns can be seen as a natural experiment to test the longer-term effect of BPIs under conditions of increased uncertainty.

METHOD

Opportunistic follow-up (n = 49) of a pilot randomized controlled trial (RCT) cohort (n = 62 autistic children aged 6-11 years; originally randomized to a 12-week group BPI [Predictive Parenting; n = 31] or an attention control [Psychoeducation; n = 31]) was conducted during COVID-19-related lockdowns. Measures of parent-reported child irritability and parenting stress were collected at 3 time points (baseline: mean age = 6.7 years; primary endpoint: mean age = 7.1 years, ∼5 months after randomization; and COVID-19 follow-up: mean age = 8.8 years, ∼2 years after randomization). We tested the magnitude of intervention effects using point estimates of differences in child irritability and parenting stress between arms at primary endpoint and COVID-19 follow-up, covarying for baseline scores. We used area under the curve (AUC) analyses to obtain overall estimates of the average intervention effect across all 3 timepoints. Semi-structured qualitative interviews were conducted with a subsample of parents (n = 18).

RESULTS

A small but significant intervention effect was found from baseline to COVID-19 follow-up in favor of Predictive Parenting on parent-reported child irritability (d = -0.33, 95% CI = -0.65, -0.01) and parenting stress (d = -0.31, 95% CI = -0.59, -0.03). No overall mean intervention effect for these measures as estimated by the AUC analyses (which takes into account the nonsignificant effect at primary endpoint) was found. Interview feedback on the both interventions was positive, and parents reported using strategies from Predictive Parenting during COVID-19-related restrictions.

CONCLUSION

This opportunistic follow-up study at a time of stress indicates the need for careful consideration of how and when to measure the effects of BPIs in autistic child populations. Future trials should consider both the most appropriate endpoint and in what context effects may be more likely to be seen.

A Waitlist Randomized Implementation Trial of Classroom Pivotal Response Teaching for Students With Autism

Classroom Pivotal Response Teaching (CPRT) is a community-partnered adaptation of a naturalistic developmental behavioral intervention identified as an evidence-based practice for autistic children. The current study evaluated student outcomes in a randomized, wait-list controlled implementation trial across classrooms. Participants included teachers (n = 126) and students with autism (n = 308). Teachers participated in 12 hours of didactic, interactive training and additional in-classroom coaching. Generalized Estimating Equations accounted for clustering. Adjusted models evaluated the relative effects of training group, CPRT fidelity, and classroom quality on student outcomes. Results indicate higher CPRT fidelity was associated with greater increases in student learning. Having received CPRT training predicted increased student engagement and greater decreases in reported approach/withdrawal problems. These differences may be linked to the theoretical foundations of CPRT of increasing student motivation and engagement and collaborative adaptation to increase feasibility in schools. Overall, results suggest CPRT may be a beneficial approach for supporting autistic students.

An initial trial of OPT-In-Early: An online training program for caregivers of autistic children

LAY ABSTRACT

Early intervention can help children learn language and improve social communication. However, many barriers, including the expense of services and an insufficient number of providers, prohibit families from accessing services when their children are young. We developed a comprehensive online program for caregivers of autistic children. The program, Online Parent Training in Early Behavioral Intervention (OPT-In-Early), uses text and video demonstrations to teach caregivers effective methods for improving their children's language, social, and adaptive skills (e.g. using utensils, toilet training), and reducing their children's disruptive behavior. Sixty-three parents from three states participated in the study. Half of the parents received access to the OPT-In-Early program. After 4 months, parents who had access to the OPT-In-Early program learned more effective intervention strategies, and started using these strategies during interactions with their children, than parents who did not receive access to the program. Parent participation in OPT-In-Early did not significantly influence children's social communication compared to children whose parents did not have access to OPT-In-Early. A longer duration of parents using learned intervention skills with their children may be needed for children's social communication skills to improve.

Using implementation science frameworks to explore barriers and facilitators for parents' use of therapeutic strategies following a parent-mediated autism intervention

LAY ABSTRACT

Many early autism interventions teach parents therapeutic strategies to help them adjust their communication style with their children. Research has shown that this behaviour change in parents leads to improvements in child communication. It is, therefore, important to learn what factors support or hinder parents in their use of therapeutic strategies learned in such interventions. This study set out to interview parents who had participated in a research trial of the Paediatric Autism Communication Therapy-Generalised intervention. We interviewed 27 caregivers and explored their use of the strategies up to 2 years after the end of the research trial. Qualitative frameworks were used to inform interview questions and data analysis. These frameworks focused on a range of contextual factors, including parents' characteristics, their context and features of the intervention. Parents reported barriers and facilitators to using Paediatric Autism Communication Therapy-Generalised strategies across three themes: Motivating Factors; Opportunity and Support; Parent Characteristics. One of these themes, Motivating Factors, was further divided into the subthemes Compatibility and Buy-In and Alignment of Goals and Outcomes. Almost all parents reported continued use of the Paediatric Autism Communication Therapy-Generalised strategies. Facilitators included parental confidence in using the strategies and barriers included child's behaviour. Consideration of these factors can inform ways to better support parents in future autism interventions.

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.

Parent-Implemented Positive Behavior Support Strategies for Young Children on the Autism Spectrum: A Pilot Investigation

PURPOSE

Parents of children on the autism spectrum enrolled in early intervention often receive coaching to address both social communication and disruptive behavior, which are the two most frequently reported concerns by parents. Intervention techniques for both are often recommended to be implemented across daily routines and require the parents to learn new ways of interacting with their child. A sequential approach to instructing parents in these key intervention targets may reduce burden and increase adherence.

METHOD

This multiple-baseline design pilot study included three mother-child dyads who received instruction in a disruptive behavior intervention immediately following a social communication intervention. Maternal maintenance of social communication strategies and child disruptive behaviors were measured during probes throughout the study.

RESULTS

Results indicate that although mothers readily learned to implement the techniques, fidelity of implementing social communication strategies declined after introduction of the positive behavior support strategies.

CONCLUSIONS

A sequenced approach to parent-mediated intervention is feasible and acceptable. Clinical implications and future directions are discussed.

The effectiveness of training community mental health therapists in an evidence-based intervention for ASD: Findings from a hybrid effectiveness-implementation trial in outpatient and school-based mental health services

LAY ABSTRACT

Publicly funded mental health services play an important role in caring for school-age children with autism spectrum disorder (ASD); however, therapists report a lack of specialized ASD training, which families identity as a barrier in obtaining mental health services for their children. An Individualized Mental Health Intervention for ASD (AIM HI) was developed in collaboration with community stakeholders to respond to identified needs of children and community therapists. The current study examined the effects of therapist training in AIM HI on the changes in therapist practice, including therapists' use of evidence-based intervention strategies in session. Data were collected from a study conducted in community outpatient and school based mental health programs randomly assigned to receive AIM HI therapist training or observation of routine care. Therapist and child clients were enrolled from participating programs. Therapists in AIM HI training received training and consultation for 6 months while delivering the AIM HI intervention to a participating client; therapists in usual care delivered routine care. Both groups of therapists video recorded psychotherapy sessions which were scored by trained raters. Differences between training groups were examined using multilevel modeling. Therapists trained in AIM HI were observed to use more extensive active teaching strategies with caregivers, engagement strategies with children, strategies promoting continuity of care, and had more structured sessions with more effective pursuit of caregiver and children skill teaching. Therapist licensure moderated some training outcomes.

Mental Health Therapist Perspectives on the Role of Executive Functioning in Children's Mental Health Services

Executive functioning is considered a key transdiagnostic factor underlying multiple mental health conditions. Evidence-based interventions targeting executive functioning skills exist and there are ongoing efforts to implement these interventions in routine community-based care. However, there is limited research characterizing therapist perspectives regarding addressing executive functioning within community-based mental health services. The current mixed-methods study aims to characterize mental health therapist perspectives regarding the role of executive functioning in youth clinical presentation and the psychotherapy process and outcomes as well as their experience and training related to executive functioning. Forty-three therapists completed a survey about their perspectives about executive functioning and 14 participated in subsequent focus groups to expand survey results. Results indicated that therapists perceive executive functioning challenges as impacting a large portion of children on their caseload, present across multiple mental health conditions, and that executive functioning is frequently a focus of psychotherapy. Therapists also identified executive functioning challenges as a barrier to therapy engagement and effectiveness. However, therapists reported limited knowledge and training as well as significant motivation for executive functioning training, including executive functioning interventions. Findings confirm the significant role of executive functioning in youth presenting for mental health services and the psychotherapy process and outcomes. Findings also highlight the need for further translation of evidence-based interventions and tools. Challenges as well as potential solutions to inform ongoing and future work seeking to translate and implement evidence-based executive functioning interventions in community mental health services are discussed.

A Systematic Review of Mental Health Interventions for ASD: Characterizing Interventions, Intervention Adaptations, and Implementation Outcomes

Youth with autism spectrum disorder (ASD) have high rates of co-occurring mental health needs that necessitate mental health interventions. Given the unique clinical characteristics of youth with ASD, there have been significant efforts to adapt and test mental health interventions for this population. Yet, characterization of the nature and types of interventions adaptations is limited, especially across the wide range of interventions tested for youth with ASD with a focus on implementation factors. Additionally, understanding how these interventions may be implemented in community services is limited. The aims of this systematic review are to characterize the (1) types of interventions tested for co-occurring mental health conditions for youth with ASD; (2) adaptations to mental health interventions for use with youth with ASD; and (3) implementation strategies, outcomes, and determinants of mental health interventions to inform their translation to community service settings. Eighty-three articles testing interventions targeting mental health symptoms in youth with ASD that included implementation factors in analyses were reviewed. The Stirman et al. (2013; 2019) FRAME adaptation, Powell et al. (2012;2015) implementation strategies, and Proctor et al. (2011) implementation outcomes taxonomies were applied to characterize the nature and types of adaptations for use with youth with ASD and types of implementation strategies, outcomes, and determinants used, when available, respectively. Of the interventions examined, the majority (64.1%) were originally designed to target youth mental health concerns and were then adapted to be used with ASD. The most common adaptations included those to the intervention content, particularly adding elements with tailoring or refining aspects of the intervention while maintaining core functions. Half of the articles described at least one implementation strategy used during intervention testing. Fidelity and acceptability were the most frequently examined implementation outcomes, with some examination of appropriateness and feasibility. Nineteen percent of articles described implementation determinants (i.e. barriers/facilitators) of these implementation outcomes. The common adaptations for ASD provide direction for future intervention development and for training community therapists. Further examination, specification, and reporting of implementation strategies and outcomes within ongoing efforts to adapt and interventions to meet the co-occurring mental health needs of youth ASD are needed to facilitate their translation to community settings. Areas for future research as well as clinical implications are discussed.

Editorial: One Good Thing (Sometimes) Leads to Another: Demonstrating Mechanistic Connections Between Parent and Child Outcomes in a Community Implementation Autism Trial

This is an important study for several reasons and shows a positive way forward for the design, execution, and analysis of intervention trials in the autism field. Brookman-Frazee et al.¹ present a novel analysis demonstrating that their community training program, An Individualized Mental Health Intervention (AIM HI), which has been shown to improve behaviors that challenge in young children with autism,² also leads to improvements in parental sense of competence (but not caregiver strain). This is in line with a limited number of other recent studies that have addressed the same issue.^3,4 The present report adds to our knowledge in at least 2 important ways; both investigating the mechanisms of how these outcomes might come about. First, the study demonstrates that implementation of the training during the period of intervention, specifically, continuity across treatment sessions and the effectiveness with which a therapist pursued teaching a caregiver skill, mediated improvements in parental sense of competence at the end of treatment. Of note, these process or fidelity implementation ratings were blind coded by naïve raters trained to reliability on video-recorded sessions, an example of the high-quality methodology valued by expert trialists. Second, the authors not only show that changes in parental sense of competence during the intervention are associated with reductions in child behaviors that challenge at the end of the treatment period, they also conducted a formal mediation analysis that further demonstrates that changes in parental sense of competence during the treatment period are related to improvements in child outcomes at 12 and 18 months, long after the intervention period itself. There have long been calls highlighting the value of such mechanistic analysis to get "maximum value" from the precious resource of intervention trials,⁵ but these have only rarely been taken up in the autism intervention field.⁶.

Impact of Therapist Training on Parent Attendance in Mental Health Services for Children with ASD

OBJECTIVE

The current study explored the impact of training therapists in a mental health intervention for children with autism spectrum disorder (ASD) on parent attendance in their children's therapy sessions. We also examined family, therapist, and program factors as potential moderators.

METHOD

Data were drawn from a cluster-randomized community effectiveness trial of "An Individualized Mental Health Intervention for ASD (AIM HI)". Participants included 168 therapists yoked with 189 children recruited from publicly-funded mental health services. Data included family (caregiver strain, parent sense of competence, race/ethnicity), therapist (background, experience), and program (service setting) characteristics, and parent session attendance. Multilevel models were used to evaluate the effectiveness of AIM HI therapist training on caregiver attendance and identify moderators of training effects on parent attendance.

RESULTS

Parents attended a higher percentage of sessions in the AIM HI training condition compared to the Usual Care condition. Program service setting moderated the effect of AIM HI training, with higher parent attendance in non-school (mostly outpatient) settings compared to school settings and a significantly smaller difference between the settings in the AIM HI condition.

CONCLUSIONS

Effective strategies to promote parent engagement, especially in service settings such as schools, are warranted. Findings support the effectiveness of AIM HI training in promoting parent attendance across multiple publicly-funded mental health service settings. The larger effect in school-based programs supports the utility of training in evidence-based interventions such as AIM HI to increase the feasibility of parent attendance in such services.
