Using Causative Methods to Determine System-Level Factors Driving the Uptake and Use of Evidence-Based Practices in a Public Early Intervention System.

Part C Early Intervention (EI) systems are an entry point to services for autistic toddlers and can be leveraged to facilitate access to autism evidence-based practices (EBPs). However, EI systems are complex and limited research has examined how an EI system's infrastructure (i.e. system-level factors) impacts the adoption and implementation of EBPs. To address this gap, 36 EI providers and 9 EI administrators completed a semi-structured interview or focus group about factors impacting the implementation of autism EBPs. Qualitative analysis included a combination of grounded theory and causative coding. Analyses were refined by input from providers, administrators, and family stakeholders in the form of round tables and presentations at the state's interagency coordinating council. Primary themes centered on: (1) the costs associated with independent contracting structures; (2) operational demands; (3) workforce stability; (4) communication consistency; and (5) implementation supports for EBP implementation. Causative coding helped to demonstrate the perceived relationships between these factors and underscored the important role of incentivization structures, collaboration opportunities, and championing in supporting the use of EBPs within a system that primarily uses independent contracting structures. The current study extends previous research by demonstrating how several system-level factors are perceived to play a role in the adoption and implementation of EBPs by independently contracted EI providers. These findings underscore the need for implementation strategies, such as incentivization strategies and social network building, to increase providers' implementation of autism EBPs within EI systems.

A Mixed-methods Examination of Culturally Responsive Adaptation to an Evidence-based Parent-mediated Intervention Implemented for Autistic Children.

Parent-mediated interventions (PMIs) are considered an evidence-based practice for fostering social communication skills in young autistic children and for promoting parent responsivity and empowerment, yet barriers to caregiver engagement are evident when PMIs are implemented within historically underserved community settings. Issues of caregiver engagement can reflect a lack of fit between PMIs and the needs of diverse families. We used a mixed methods approach to examine barriers to participating in an evidence-based PMI, Project ImPACT (Ingersoll & Dvortcsak, 2019), within an outpatient setting, as well as strategies that clinicians reported using to deliver and adapt Project ImPACT for minoritized families. Participants included 134 caregivers of a child 13 to 48 months with autism or other social communication differences and six clinicians delivering Project ImPACT. Findings suggest that caregivers experience barriers to participating in Project ImPACT and that these barriers are associated with caregivers' ability to complete the program. Although quantitative findings indicate that adaptation to Project ImPACT did not differ by caregiver and child background, qualitative findings highlighted that clinicians attempt to deliver Project ImPACT to respond to the needs of families from minoritized backgrounds by actively considering the family's culture, psychosocial experiences, goals, and specific barriers. Further, both qualitative and quantitative findings suggest that culturally responsive care and adaptations may support caregiver engagement, including rapport, trust, buy-in, and attendance. Approaches to center cultural alongside contextual/psychosocial considerations within family-centered care in the implementation of PMIs are also highlighted.
