| Abstract: |
There is an increasing need to measure caregiver implementation of strategies from Naturalistic Developmental Behavioral Interventions (NDBIs) as a possible key mediator of outcomes in a child. The NDBI Fidelity (NDBI-Fi) rating scheme is a macro-code to estimate the implementation of core strategies. Yet, there is a need to understand the dependability of this measure to ensure intervention study findings are generalizable to everyday interactions and comparable across studies. We addressed this by evaluating the dependability or consistency of NDBI-Fi scores for 20 caregivers, averaged across observations of two occasions of two routines that were each scored by two raters. Our findings indicated that a single score (i.e. from a single occasion, single routine, and single rater) from the measure has low dependability (g = 0.43). When scores were averaged across two observations each of two routines scored by two raters (i.e. eight scores total), the score was more dependable (g = 0.77). The majority (81.6%) of absolute error variance was attributable to occasions of observation and its interaction with other facets (routine or rater). Therefore, we recommend the NDBI-Fi be applied to more than one observation of more than one routine to strengthen confidence that scores are generalizable to everyday parent-child interactions. |
