Control Attitudes Scale-Revised-Brazilian Version.
The Journal of cardiovascular nursing(2023)
摘要
BACKGROUND:Heart failure demands self-care skills and behaviors that can be negatively impacted by a low level of perceived control (PC), a belief about having the necessary resources to deal with negative events. Having valid and reliable instruments to measure PC is important to support interventions that improve self-care and related outcomes. The Control Attitudes Scale-Revised (CAS-R) was developed in the United States to measure PC in cardiac conditions. In Brazil, there are no instruments available to measure this construct.
OBJECTIVE:The aims of this study were to translate and adapt the CAS-R to the Brazilian population and to assess the content validity of the adapted version.
METHODS:The CAS-R was translated, back-translated, and assessed by an expert committee for linguistic equivalences. An agreement > 80% was considered adequate. Content validity (clarity, theoretical relevance, and practical pertinence) was assessed by both an expert professional panel (n = 6-8) and a panel of patients with heart failure (n = 40). A content validity coefficient > 0.70 was considered acceptable.
RESULTS:The translations to Brazilian Portuguese were considered consistent with the original CAS-R. In the third round of linguistic equivalence assessment, all items achieved acceptable agreement, except for 2 items. After modifications to the instrument to achieve adequate equivalences, the adapted version had a final content validity coefficient of 0.93. Most patients were able to understand the instrument.
CONCLUSIONS:The CAS-R-Brazilian version is equivalent to the original CAS-R and has satisfactory evidence of content validity. Additional psychometric testing will be performed to allow for the assessment of PC in individuals with heart failure in Brazil.
