How Tailoring Led to Variation in Care Issues, Dosage, and Outcomes: Part 1: Secondary Analysis of the PREP Trial for Frail Older Adults and Family Caregivers.

In family caregiving interventions for adults with health problems, tailoring has become the norm. Studies that evaluate tailored interventions, however, have rarely included intentional variation in dosage or explored the dosage-outcome association. In this Part 1 secondary analysis, we examine dosage and outcomes in intervention families ( = 116) who participated in the Oregon Health & Science University/Kaiser Permanente Northwest Region Family Care Study.
