Representational Post-MI Nursing Intervention

描述（由申请人提供）：本R 03申请寻求2年的支持，以进行心肌梗死（MI）康复者护理干预的方法学开发和试点实施。干预将针对患者对MI和冠心病（CHD）的常识模型或认知表征中的误解进行修改，最终目标是促进健康行为并改善生活质量。护理干预将使用半结构化的电话脚本，以加强患者对冠心病的准确信念，同时创造条件，有利于修改冠心病相关的误解，通过应用原则，从社会心理学文献的说服。此外，干预措施将针对参与者的CHD风险因素及其对MI的独特认知表现进行调整。发展这种干预措施是重要的，原因有二。首先，对冠心病的误解在从MI恢复的患者中非常常见，这种误解预示着不遵守MI后关于饮食、运动和戒烟的建议。其次，CHD相关的误解在MI后女性中尤其明显，可能导致CHD结局的性别差异。拟议的R 03项目将解决三个具体目标：（1）开发的材料和程序的护理干预;（2）试点测试的干预样本中的24名心肌梗死患者使用单因素受试者之间的实验设计;（3）评估的可行性测试干预在更大的规模。初步研究将包括在出院后1周通过电话评估MI和CHD的表现。治疗组受试者将在出院后2周接受电话干预，对照组受试者接受标准护理。将在8周后收集有关健康行为、症状和生活质量的结局数据。试验数据将用于完善方案并进行功效分析。

DESCRIPTION (provided by the applicant): This R03 application seeks 2 years of support to undertake the methodological development and pilot implementation of a nursing intervention for persons recovering from myocardial infarction (MI). The intervention will target the modification of misconceptions in patients' common sense models - or cognitive representations - of MI and coronary heart disease (CHD), with the ultimate goal of facilitating healthy behaviors and improving quality of life. The nursing intervention will use semi-structured telephone scripts to reinforce patients' accurate beliefs about CHD, while creating conditions conducive to the modification of CHD-related misconceptions through the application of principles from the social psychological literature on persuasion. In addition, the intervention will be tailored to participants' CHD risk factors and their unique cognitive representations of MI. The development of such an intervention is important for two reasons. First, misconceptions about CHD are very common among patients recovering from MI and such misconceptions predict non-adherence to post-MI recommendations regarding diet, exercise, and smoking cessation. Second, CHD-related misconceptions are especially pronounced among post-MI women and may contribute to gender disparities in CHD outcomes. The proposed R03 project will address three specific aims: (1) development of the materials and procedures for the nursing intervention; (2) pilot testing the intervention in a sample of 24 post-MI patients using a single-factor between-subjects experimental design; and (3) evaluating the feasibility of testing the intervention on a larger scale. The pilot study will involve assessing representations of MI and CHD by telephone at 1-week post-hospital discharge. Participants in the treatment group will receive the telephone intervention at 2 weeks post-discharge, with those in the control group receiving standard care. Outcome data regarding health behaviors, symptoms, and quality of life will be collected after 8-weeks. Pilot data will be used to refine the protocol and conduct a power analysis.
