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

Abstract

Cardiac rehabilitation is supported by the highest level of scientific evidence. However, less than 25% of those eligible to participate in a cardiac rehabilitation program initiate it; and of these, 50% drop out prematurely. A modified Spanish Cardiac Rehabilitation Barriers Scale (CRBS) has been translated, culturally adapted and validated in Colombia, however, the reliability remains to be evaluated. This study aimed to determine the internal consistency and test–retest reliability of the CRBS in a Colombian population. In total, 193 patients (67% men, average age = 65 ± 12 years) completed the scale twice, with an average of eight days between applications. Cronbach’s Alpha and intraclass correlation coefficients (ICC) were calculated. The internal consistency of the Colombian version of the CRBS was acceptable (Cronbach’s alpha = 0.84). The ICC of the CRBS was 0.69 (95% CI 0.61–0.76); 0.78 (95% CI 0.71–0.84) when the CRBS was completed by interview; and 0.47 (95% CI 0.21–0.67) when the CRBS was self-reported. The reliability of the interview version of the CRBS was substantial in the Colombian population; however, the reliability of the self-report version was lower. The use of this scale will allow developing strategies to increase participation and adherence to cardiac rehabilitation programs.

Validity and Reliability of the Cardiac Rehabilitation Barriers Scale in the Czech Republic (CRBS-CZE): Determination of Key Barriers in East-Central Europe

“…Through this study, the psychometric validity and reliability of the Czech version of the CRBS were established. Results are consistent with other versions of the CRBS, identifying four subscales [ 18 , 26 , 29 , 31 ]. However, in this translation, healthcare system factors hung together with comorbidities, rather than perceived need; this may explain the low internal reliability of the latter subscale, which is a limitation of this translation.…”

“…Despite robust evidence of the benefits of CR, even of each additional session attended [ 25 ], utilization remains low [ 9 ]. Patient’s barriers to CR utilization should be evaluated, hence the emergence of the CRBS and its 15 translations [ 18 , 26 , 27 , 28 , 29 , 30 , 31 ]. In the Czech Republic, data on barriers and patient participation in CR are lacking.…”

“…The other study aim was to identify key CR barriers in our region, as these do differ significantly by context [ 18 , 26 , 27 , 28 , 29 , 30 , 31 ]. Distance from the CR facility was rated as the most significant barrier.…”

Translation, Cross-Cultural Adaptation and Psychometric Validation of the Arabic Version of the Cardiac Rehabilitation Barriers Scale (CRBS-A) with Strategies to Mitigate Barriers

“…Indeed, the CRBS has now been administered in four EMR countries (i.e., Qatar [ 9 ], Iran [ 23 , 24 ], Saudi Arabia, Jordan), establishing that it is valid in the socio-religious context as well. The CRBS has been administered in other countries with very low CR availability [ 25 ] such as Brazil [ 26 , 27 , 28 , 29 , 30 , 31 ], Colombia [ 32 , 33 , 34 ], Iran [ 23 , 24 ], Czechia [ 35 ], Indonesia [ 36 ], China [ 37 , 38 , 39 , 40 ], Malaysia [ 41 , 42 ], and South Korea [ 43 , 44 ], again supporting its applicability globally. This may have been the first study however where the CRBS has been administered in a context without available CR, which did render it infeasible to fully assess construct and criterion validity.…”
