Observing home-visiting quality across time: A longitudinal reliability study of the Home Visit Rating Scales.

Empirical examination of home-visiting quality over time is lacking in the research literature. To this end, this study examined the most recent edition of a widely used observational measure of home-visiting quality, the Home Visit Rating Scales (HOVRS), over four repeated assessments spanning an average of 6 months. Psychometric quality for the HOVRS Total and Home Visitor Practice Scales, including item ratings and calculated scores, across time was demonstrated.
