DESCRIPTION (provided by applicant): Cardiovascular disease accounts for 50% of all deaths in the United States. While participation in Cardiac Rehabilitation (CR) significantly reduces re-hospitalization and mortality among cardiac patients, the impact of CR on public health is substantially weakened due to poor maintenance of health behaviors, particularly physical activity, after CR is ended. The goal of the proposed project is to test the efficacy of a tailored, motivation-matched intervention to enhance the maintenance of physical activity following CR. The overall scientific question posed by this project is: Can a low-cost, motivationally-tailored intervention delivered via computer expert system significantly improve patients' physical activity participation in the year following phase II cardiac rehabilitation? A two-group design will compare: 1) CR with Tailored Support (Tailored), versus 2) Care as usual following CR (Standard Care). This project utilizes a repeated measures design consisting of baseline (at completion of phase II CR), and follow-up at one, three, six, nine and twelve months. Exercise tolerance tests will be used to validate the primary outcome of self-reported exercise participation. Analyses of important cognitive-behavioral mediators of the intervention efficacy and cost efficacy analyses will be performed. This proposal responds to recommendations of the NHLBI calling for additional research into cost effective behavioral interventions for use in large populations and which target the identification of factors which enhance adherence to preventive behaviors (USDHHS, 1995; 2001), and an NIH joint initiative to investigate innovative approaches to disease prevention through behavior change (1997).

描述（由申请人提供）：心血管疾病占美国所有死亡人数的50%。虽然参与心脏康复（CR）显著降低了心脏病患者的再住院率和死亡率，但由于CR结束后健康行为（特别是体力活动）维持不良，CR对公共卫生的影响大大减弱。该项目的目标是测试定制的，动机匹配的干预措施，以提高CR后的体力活动的维持的有效性。该项目提出的总体科学问题是：通过计算机专家系统提供的低成本、动机定制的干预能否显著改善患者在第二阶段心脏康复后一年的身体活动参与？两组设计将比较：1）CR与定制支持（定制），与2）CR后的常规护理（标准护理）。本项目采用重复测量设计，包括基线（完成第二阶段CR时）和1、3、6、9和12个月的随访。运动耐量试验将用于验证自我报告的运动参与的主要结局。将进行干预有效性和成本有效性分析的重要认知行为介质分析。该提案响应了NHLBI的建议，该建议呼吁对用于大规模人群的成本效益行为干预进行额外研究，并以确定增强坚持预防行为的因素为目标（USDHHS，1995; 2001），以及NIH联合倡议调查通过行为改变预防疾病的创新方法（1997）。
