Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Area of Science:

Implementation science
Community-based participatory research
Public health program evaluation

Background:

Measuring implementation fidelity is critical for program success but challenging in dispersed community settings.
Observational methods are ideal but often impractical due to resource limitations.
Engaging community members as paid research staff can build local capacity for direct observations.

Purpose of the Study:

To develop and assess the utility of a fidelity measure for the Building Healthy Families (BHF) program.
To create and evaluate a training protocol for hiring and training local community members as direct observers.

Main Methods:

A consensus process informed the development of a comprehensive direct observation fidelity measure.
A qualitative iterative approach with observers was used for piloting and refinement.
A training protocol was developed to hire and train community members as direct observers for geographically dispersed sites.
Inter-rater agreement of ≥85% with an expert observer was the benchmark for independent assessment.

Main Results:

A multidimensional fidelity measure tailored to the BHF program was successfully developed.
Community-based observers (n=5) were trained to conduct fidelity assessments comparable to research team observers (n=3).
All training sessions achieved ≥85% inter-rater agreement with an expert observer.
The fidelity measure proved highly useful, capturing multiple dimensions and offering insights for consistent program implementation.

Conclusions:

A systematic approach for assessing family healthy weight program (FHWP) implementation fidelity in rural and micropolitan areas was established.
Hiring and training local community members as direct observers improved the feasibility of fidelity measurement across dispersed settings.
This study presents a viable model for ongoing implementation fidelity assessments in community-based programs.
