Pilot Testing and Adaptation of the NDBI-FI for Group-Based Settings

Principal Investigator: Allison Jobin, Ph.D., BCBA-D

This study addresses the need for feasible and context relevant intervention fidelity tools for measuring implementation of naturalistic developmental behavioral interventions (NDBI) in group-based settings. A particular advancement in the area of autism intervention research is the development and initial validation of fidelity measurement tools for common strategies comprising treatment under the umbrella of NDBIs (e.g., NDBI-FI; Frost et al., 2020). However, the NDBI-FI was developed to measure fidelity to intervention delivered by caregivers in a one-to-one context. It was not designed for nor has it been tested in group treatment delivery environments. Thus, this community-partnered study (collaborative with Alexa’s PLAYC of Rady Children’s Hospital) involves the adaptation of the NDBI-FI tool for use the group inclusion setting, evaluation of the feasibility and acceptability of the adapted measure, and measurement of the preliminary psychometric properties when used in the group context.
