Summary
A new questionnaire effectively measures exercise attitudes and behavior intentions in aortic dissection (AD) survivors. This reliable and valid tool aids in assessing exercise behavior for AD patients.
Area of Science:
- Cardiovascular Medicine
- Rehabilitation Science
- Psychometrics
Background:
- Aortic dissection (AD) survivors require tailored strategies to manage exercise behavior.
- Assessing exercise attitudes and intentions is crucial for effective rehabilitation post-AD.
- Existing tools may not adequately capture the specific needs of AD survivors.
Purpose of the Study:
- To develop and validate a questionnaire assessing exercise attitudes and behavior intentions in aortic dissection survivors.
- To create a reliable and valid instrument for measuring exercise-related psychological factors in AD patients.
Main Methods:
- The study involved two phases: questionnaire development (literature review, interviews, Delphi, pre-experiment) and validation in 160 AD survivors.
- Exploratory factor analysis identified 11 components, explaining 75.216% of variance.
- Reliability and validity were assessed using content validity index, item-scale correlations, Cronbach's alpha, and split-half reliability.
Main Results:
- A 62-item Exercise Attitudes and Behavior Intentions Questionnaire (EABIQ) for AD survivors was developed.
- High content validity (Item-CVI: 0.813-1.000, S-CVI/Ave: 0.934) and construct validity (item-scale correlations: 0.405-0.785, p<0.05) were demonstrated.
- Excellent internal consistency (Cronbach's alpha: 0.929 overall, 0.835-0.965 per domain) and split-half reliability (0.960 overall, 0.844-0.962 per domain) were confirmed.
Conclusions:
- The developed EABIQ for AD survivors exhibits high reliability and validity.
- The questionnaire aligns with theoretical frameworks and is suitable for measuring exercise behavior in AD patients.
- This tool can guide interventions aimed at improving exercise adherence among aortic dissection survivors.

A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities

Introduction
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.

Exercise significantly impacts cardiovascular response, which is crucial for understanding patient health and designing effective treatment plans.
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

02:01Factorial Design
13.0K
Factorial Analysis is an experimental design that applies Analysis of Variance (ANOVA) statistical procedures to examine a change in a dependent variable due to more than one independent variable, also known as factors. Changes in worker productivity can be reasoned, for example, to be influenced by salary and other conditions, such as skill level. One way to test this hypothesis is by categorizing salary into three levels (low, moderate, and high) and skills sets into two levels (entry level...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
