The Multiple Risk Factor Intervention Trial (MRFIT) simultaneously intervenes on three major risk factors for coronary heart disease: Hypercholesteremia, hypertension, and cigarette smoking. It was, therefore, essential to develop intervention strategies which would be appropriate across all modalities. The initial methodology combines the transfer of basic information, the use of small groups of participants and their homemakers to facilitate changes in life style, and the use of the principles of behavioral change and maintenance theory to encourage long-term success in adapting and maintaining new habits over a life time.
多重危险因素干预试验（MRFIT）同时针对冠心病的三个主要危险因素进行干预：高胆固醇血症、高血压和吸烟。因此，制定适用于所有方式的干预策略至关重要。最初的方法包括传递基本信息，利用一小群参与者及其家庭主妇来促进生活方式的改变，以及运用行为改变和维持理论的原则来鼓励在一生中成功适应和维持新习惯并取得长期成效。
