Cross-cultural adaptation and validation to Brazil of the Medication Counseling Behavior Guidelines

Abstract

This work aimed to translate cross-culturally adapts, and validate the "Medication Counseling Behavior Guidelines" instrument into Brazilian Portuguese. The process of cross-cultural adaptation was carried out using international recommendations. The generated versions were evaluated for the semantic, idiomatic, cultural, and conceptual equivalences and the pre-test was carried out with undergraduate pharmacy students. The reliability of the instrument was evaluated through inter-observer reliability, test-retest, and internal consistency tests. The final version was submitted for content validation. The process of cross-cultural translation and validation result in the Brazilian-Portuguese version of the tool was done. During the translation and back-translation stages, only grammatical changes were made to establish cross-cultural equivalence between the versions under analysis. Regarding the semantic evaluation, six items (15.4%) revealed less than 80% agreement between the judges and were adjusted. Agreement greater than 80% was verified for all items assessed as cultural and conceptual equivalences. In the pre-test, four items (10.2%) were modified. Inter-observers and test-retest reliability demonstrated good to excellent reproducibility for most items (ICC = 0.60-0.98) and internal consistency was considered high (Cronbach's alpha = 0.99). Psychometric evaluation demonstrated and confirmed the validity of the Brazilian-Portuguese version of the tool to assess patient counseling practices. The tool can be used by pharmacists and undergraduate pharmacy students to improve the quality of patient counseling.

Development and validation of a scale to measure the quality of patient medication counseling using Rasch model

“…The presence of overlapping items might be one of the reasons to explain the high reliability of the overall scale in the present study. A similar study on evaluation, the Brazilian-Portuguese version of the “Medication Counseling Behavior Guidelines” — without application of Rasch analysis — by Santos et al , also found that the overall scale had high reliability with the Cronbach’s alpha coefficient of 0.99 36…”
