Younger siblings of autistic children are at a high likelihood (HL) of autism, language, and/or cognitive delays. Vocal complexity, a continuous measure of the developmental maturity of vocal communication, is facilitated by parent-child interaction and predicts language outcomes. This study examined whether parents' intervention fidelity to…

The extant literature on implementation fidelity has found mixed evidence for empirically establishing the dimensionality of implementation fidelity. The current study aims to add to this growing body of literature by examining implementation fidelity in a book-reading intervention for young children's caregivers. Caregivers (n = 291) implemented…

Family routines provide young children with predictable, repeatable, and functional contexts for learning about the world. Participating in family routines is a critical pathway by which all children learn. While the use of family routines in caregiver-implemented interventions (CIIs) is supported by theories, research, and recommended practices,…

This pilot feasibility study applies the RE-AIM Implementation Science Framework to examine the implementation and preliminary signals of the effectiveness of integrating the Group-Early Start Denver Model (G-ESDM) in an early childhood education center serving under-resourced communities. Five preschoolers diagnosed with autism, their caregivers,…

Few studies examine the effectiveness of community-based early interventions in unselected samples of autistic children, especially those from minoritized backgrounds. These types of studies require attention to strategies for recruitment, retention, data collection, and support for community providers beyond those used in university-based trials.…

Increased numbers of young children identified with autism combine with changing paradigms for service delivery models to create a need to ensure that information is available to facilitate implementation of effective practices in children's natural learning environments. A recent synthesis that identifies evidence-based practices (EBPs) for…

For children with complex communication needs (CCN), augmentative and alternative communication (AAC) devices offer a means to communicate and participate in daily activities. Effective implementation and intervention practices are needed for supporting teaching teams working with children with CCN to improve child use of AAC. The purpose of this…

An implementation science framework is used to differentiate between two types of practices (implementation and intervention) and to describe how the fidelity of the two practices are related and would be expected to influence outcomes of interest. The two practices are the methods and procedures used by implementation agents (e.g., a coach) to…

Fidelity assessment has received renewed attention in recent years, particularly as distinctions have been made in implementation science between intervention fidelity and implementation fidelity. Considering both types of fidelity has been recommended when developing fidelity instruments. In the present article, we describe development of the…

Structural, process, and content dimensions of a coaching-based professional development (PD) intervention were examined in an implementation fidelity study. The intervention focused on Head Start teachers' vocabulary and phonemic awareness instruction, and was delivered through onsite classroom visits and technologically mediated methods that…

The purpose of this review was to analyze fidelity features in parent-implemented interventions for young children with disabilities. The authors conducted a review of 24 studies published in nine peer-reviewed journals. Each identified article was scored on the following categories: the participant characteristics, settings, study design,…

More than a decade has passed since the National Research Council described the common elements of effective educational programs for young children with autism. Since that time, few studies have attempted to understand the mechanisms of change and factors affecting the effectiveness of research supported interventions implemented in community…
