Abstract

A randomized trial involving 1,351 new Medicare enrollees was conducted to assess the efficacy of a transtheoretical model (TTM) based manual and multimedia expert system program that delivered guidance and feedback matched to individual stage of readiness to compare Medicare health plans. At 6 months post-intervention, compared to enrollees in the control group, those receiving the manual plus expert system intervention or the manual alone exhibited greater increases in Medicare knowledge. The TTM-based interventions also increased use of and satisfaction with traditional Medicare education materials among most enrollees. The interventions' impact on stage of change for comparing plans was observed only among treatment group participants who had examined and evaluated the materials. The challenges to increasing informed choice and possible dissemination channels for stage-based materials are discussed.
