Translation, Cross-cultural Adaptation and Psychometric Validation of the Korean-Language Cardiac Rehabilitation Barriers Scale (CRBS-K)

Abstract

ObjectiveTo perform a translation and cross-cultural adaptation of the Cardiac Rehabilitation Barriers Scale (CRBS) for use in Korea, followed by psychometric validation. The CRBS was developed to assess patients' perception of the degree to which patient, provider and health system-level barriers affect their cardiac rehabilitation (CR) participation.MethodsThe CRBS consists of 21 items (barriers to adherence) rated on a 5-point Likert scale. The first phase was to translate and cross-culturally adapt the CRBS to the Korean language. After back-translation, both versions were reviewed by a committee. The face validity was assessed in a sample of Korean patients (n=53) with history of acute myocardial infarction that did not participate in CR through semi-structured interviews. The second phase was to assess the construct and criterion validity of the Korean translation as well as internal reliability, through administration of the translated version in 104 patients, principle component analysis with varimax rotation and cross-referencing against CR use, respectively.ResultsThe length, readability, and clarity of the questionnaire were rated well, demonstrating face validity. Analysis revealed a six-factor solution, demonstrating construct validity. Cronbach's alpha was greater than 0.65. Barriers rated highest included not knowing about CR and not being contacted by a program. The mean CRBS score was significantly higher among non-attendees (2.71±0.26) than CR attendees (2.51±0.18) (p<0.01).ConclusionThe Korean version of CRBS has demonstrated face, content and criterion validity, suggesting it may be useful for assessing barriers to CR utilization in Korea.

Barriers to Outpatient Hospital-Based Cardiac Rehabilitation in Korean Patients With Acute Coronary Syndrome

“…The CRBS was developed to comprehensively investigate the barriers to CR [ 12 ]. The CRBS-K was developed and validated in patients with myocardial infarction from Seoul National University Bundang Hospital and Kangwon National University Hospital ( Appendix 1 ) [ 11 ]. Patient's level of agreement with each CRBS item on a 5-point Likert scale, with response options ranging from 1 (strongly disagree) to 5 (strongly agree).…”

“…The aim was to provide evidence to suggest a plan to overcome the barriers to CR. Korean version of the Cardiac Rehabilitation Barrier Scale (CRBS-K) [ 11 ] ( Appendix 1 ), which has been validated in the Korean patients with myocardial infarction, was used in this study. It is an easy-to-use tool, which may enable comprehensive screening and detection of multiple variables proven as CR barriers in previous studies, and is helpful to investigate the barriers in the multiple domains.…”

Reliability of the Scale of Barriers for Cardiac Rehabilitation in the Colombian Population

“…However, the Brazilian version is the only one that has assessed its psychometric properties in patients with cardiovascular risk factors, coronary heart disease, heart failure, arrhythmias, peripheral arterial disease and chronic obstructive pulmonary disease. Additionally, the CRBS when compared to the last two, is the only one that evaluates factors influencing participation or adherence to CRP (13,(22)(23)(24)(25)(26).…”

Validity and reliability of the turkish version of "cardiac rehabilitation barriers scale"

“…This final version is named 'Kardiyak Rehabilitasyonda Engeller Skalası' (KRES). The patients were also asked about their opinions on the construction, usefulness, and scope of the scale and their answers were evaluated via a 100 mm visual analog scale (7).…”

“…It can be applied both at enrollment and during participation and it is applicable to all cardiac patients (5). This scale has also been translated and validated in Portuguese and Korean (6,7). The aim of this study is to translate and validate this scale in Turkish.…”
