Our study aimed to develop a questionnaire to assess the reliability and validity of exercise attitudes and behavior intentions among survivors of an aortic dissection (AD).
There were two phases to the study between April 2021 and April 2022. Phase I involved the development of an initial version of the Exercise Attitudes and Behavior Intentions Questionnaire (EABIQ) through literature reviews, qualitative interviews, Delphi expert consultations and a pre-experimental study. During Phase II, the reliability and validity of the questionnaire was assessed in 160 survivors with AD.
A 62-item EABIQ for AD survivors was developed. Eleven common components with eigenvalues larger than 1 were identified by exploratory factor analysis. The scale's variance explained cumulatively rate was 75.216%. The content validity index at the item level for the EABIQ varied from 0.813 to 1.000 and the S-CVI/Ave was 0.934. The correlation coefficients between each scale dimension and the overall scale ranged from 0.405 to 0.785, with all -values less than 0.05. Cronbach's alpha for the whole scale was 0.929, with Cronbach's alpha for each domain ranging from 0.835 to 0.965. The overall scale split-half reliability coefficient was 0.960, with each domain's split-half reliability coefficient ranging from 0.844 to 0.962.
The AD exercise attitudes and behavior intentions questionnaire has high reliability and validity and is generally consistent with the hypothetical theoretical framework. It can be used as a judgment tool to measure the exercise behavior for AD patients.
本研究旨在开发一份问卷，以评估主动脉夹层（AD）幸存者运动态度和行为意向的可靠性和有效性。
2021年4月至2022年4月期间进行了两个阶段的研究。第一阶段通过文献综述、定性访谈、德尔菲专家咨询和预实验研究，开发了运动态度和行为意向问卷（EABIQ）的初始版本。在第二阶段，对160名AD幸存者进行了问卷的信效度评估。
开发了一份针对AD幸存者的62项EABIQ。通过探索性因素分析确定了11个特征值大于1的共同成分。量表的累积方差解释率为75.216%。EABIQ在项目层面的内容效度指数从0.813到1.000不等，S-CVI/Ave为0.934。各量表维度与总量表之间的相关系数在0.405至0.785之间，所有p值均小于0.05。总量表的Cronbach's alpha为0.929，各领域的Cronbach's alpha在0.835至0.965之间。总量表的分半信度系数为0.960，各领域的分半信度系数在0.844至0.962之间。
AD运动态度和行为意向问卷具有较高的信效度，与假设的理论框架基本一致。它可作为衡量AD患者运动行为的判断工具。
