The Reflective Fostering Programme fidelity rating scale: development and inter-rater reliability

Purpose The purpose of this study is to describe the development 14-item reflective fostering fidelity rating (RFFR), an observational system evaluate model group facilitators in Reflective Fostering Programme (RFP), a mentalisation-based psychoeducation programme support foster carers. authors assess usability, dimensionality, inter-rater reliability and discriminative ability RFFR. Design/methodology/approach Eighty video clip extracts documenting 20 RFP sessions were independently rated by four raters using dimensionality RFFR was assessed principal components analysis. Inter-rater agreement intra-class correlation coefficient. Findings proportion missing ratings low at 2.8%. A single component summarised over 90% variation for each rater. individual item poor-to-moderate, but summary score had acceptable reliability. present evidence that can distinguish differ treatment fidelity. Originality/value To best authors’ knowledge, first investigation report RFFR’s validity assessing RFP. paper concludes appropriate measure useful purposes both quality control supervision.
