AssessmentDevelopment and psychometric validation of the second version of the Coronary Artery Disease Education Questionnaire (CADE-Q II)☆
Introduction
Cardiovascular diseases (CVDs) are the leading cause of death worldwide [1], and a significant contributor to morbidity and health-related costs [2]. Coronary Artery Disease (CAD) – the most common type of CVD – is increasing in prevalence due to improvements in acute care. Accordingly, chronic disease management is needed to optimize secondary prevention, including patient education [3], [4], [5]. Findings from a recent systematic review confirm the benefits of educational interventions in CAD patients, through increasing knowledge and facilitation of heart health behaviour change [6].
Cardiac rehabilitation (CR) is a comprehensive risk reduction programme recommended for CVD patients [4], [5], [7]. Patients participate in CR approximately two times a week over a few months, during which time medical and lifestyle risk factors are managed, cardioprotective therapies are optimized and psychosocial health is promoted. Patient education is considered one of the core components of CR [3], [8], [9], [10], to promote patient understanding of the multitude of recommended therapies and behaviour changes, as well as their adoption and maintenance [11], [12], [13].
In order to plan and deliver an effective CR educational intervention, it is important to have precise information of what cardiac patients know about their condition [11], [14]. Accordingly, the 19-item Coronary Artery Disease Education Questionnaire (CADE-Q) was previously developed and psychometrically-validated to assess CR patients’ knowledge about CAD [15], [16], [17]. It is one of the very few available tools to measure CAD patient knowledge in the CR context that is psychometrically-validated [18], [19], [20], [21]. Although it demonstrated good reliability and validity, the CADE-Q failed to assess all the core components of cardiac rehabilitation (CR), most notably excluding nutrition and psychosocial knowledge. Considering that the focus of CR have been changed over the past years – from exercise-only to comprehensive secondary prevention [3], [6] – this second version of the CADE-Q II was developed to not only update content, but to address all components of cardiac patients’ care. For instance, psychosocial health is considered a core component of CR, and this area is now included in the scale. Therefore, the availability of a more comprehensive and updated CADE-Q is important to assess cardiac patients’ knowledge and to tailor the educational component of CR programmes [22]. The aim of this study was to develop and psychometrically-validate a revised version of the CADE-Q (CADE-Q II).

Design and procedure
This study was reviewed and approved by the University Health Network Research Ethics Board. The design consisted of a series of cross-sectional, observational studies.
The first step in this research was the development of a revised survey based on a literature review. A literature search on patient education in CR, and review of CR practice guidelines [3], [8], [9], [10] was performed to identify the most important information that coronary patients need to know about their disease and its’
Participants characteristics
For the content validation, there were 10 (75%) clinicians, and 5 (25%) researchers who reviewed the items (N = 15). For the pilot test, 50 CR graduates were contacted and 30 (60%) responded, of which 8 (27%) were female. Respondents had a mean age of 68.7 ± 8.4, and had participated in a mean (25th–75th percentile) of 15.0 ± 20.8 (1.0–29.0) months of CR.
For the psychometric validation study, 307 coronary patients (representing approximately 26% of total annual CR patients) completed the CADE-Q II.
Discussion
The development of the CADE-Q II was undertaken using best practices, and this study has demonstrated it is reliability, validity and multi-faceted structure. Since patient education is a core component of CR, the CADE-Q II will be instrumental to healthcare providers to convey what information cardiac patients need to know about CAD and its’ management, as well as to evaluate educational strategies for these patients. This initial study suggests that patients overall knowledge at the beginning

Results from a psychometric validation study conducted with patients with CAD referred to CR, who either had not yet initiated CR or were in their first week of the program (N = 307), provide good evidence for the CADE-Q-II’s reliability and validity [34]. Approximately half of participants demonstrated initial CAD knowledge ≥ 75% (≥70/93 points).
