Effects of Cardiovascular Disease Risk Communication for PatientsWith Type 2 DiabetesMellitus onRiskPerception in a Randomized Controlled Trial

RESEARCH DESIGN AND METHODSdA randomized controlled trial was performed in T2DM patients newly referred to the Diabetes Care System (DCS)West-Friesland, a managedcare system in the Netherlands. The intervention group (n = 131) received a six-step CVD risk communication. Control subjects (n = 130) received standard managed care. The primary outcome measure was appropriateness of risk perception (difference between actual CVD risk calculated by the UKPDS risk engine and risk perception). Secondary outcome measures were illness perceptions, attitude and intention to change behavior, satisfaction with the communication, and anxiety andworry about CVD risk. Patients completed questionnaires at baseline, at 2 weeks (immediately after the intervention), and at 12 weeks.
