A Brazilian Portuguese translation, cultural adaptation and validation of the Arrhythmia-Specific questionnaire in Tachycardia and Arrhythmia (ASTA) health-related quality of life (HRQOL) scale

Abstract

Introduction The health-related quality of life (HRQOL) of patients with tachyarrhythmia can be negatively influenced by the clinical manifestations. The evaluation of HRQOL with validated instruments can provide valuable information that will contribute to clinical decision-making and treatment. In Brazil, however, there is no available scale that evaluates HRQOL in different types of arrhythmia. The purpose of this study was to adapt the Arrhythmia-Specific Questionnaire in Tachycardia and Arrhythmia-HRQOL scale (ASTA-HRQOL scale) to the Brazilian culture, and to assess the psychometric properties of the adapted questionnaire. Methods The study used a methodological process of cultural adaptation based on international literature guidelines. The analyses were performed with 172 participants, 32 for cultural adaptation and 140 for psychometric validation. Calculation included analysis of reliability by Cronbach’s α coefficient, construct validity with convergent validity using the WHOQOL-BREF questionnaire and by the Spearman correlation coefficient, Average Variance Extracted, and assessment of confirmatory factor analysis. Results The translation and adaptation processes showed a satisfactory degree of comprehension and applicability (93% reported them to be easy to understand). Confirmatory factor analysis indicated exclusion of one item from the mental scale, but after qualitative analysis the item was retained. The items presented adequate internal consistency (Cronbach’s alpha coefficient = 0.88), and an inverse correlation of moderate magnitude with the physical domain (rho = -0.63) and with the mental domain (rho = -0.58) of the WHOQOL-BREF. Conclusions The Brazilian Portuguese version of the ASTA-HRQOL scale, the ASTA-Br-HRQOL scale, can be a valuable tool for use in clinical practice and research.

Development and Validation of a Revised VAS-Anxiety Measurement Tools for Preschool Hospitalized Children

“…Analysis performance was measured by the content validity index (CVI) with a four-point scoring system (from 1=not relevant to 4 = highly relevant). Item-total correlation coefficients and Cronbach's alpha after item revisions: items with a weak total item correlation coefficient or less than 0.30 will be revised or removed (Cannavan et al, 2021;Tsang, Royse, & Terkawi, 2017). The Indonesian revised VAS-Anxiety factor structure was determined using principal component analysis and varimax rotation.An absolute value was set above 0.40. the data were analyzed by SPSS software version 20.…”

“…has an item correlation value (0.49) and decreased in the second test (0.35). However, both were in the moderate category (Cannavan et al, 2021;Igwesi-Chidobe et al, 2021). The experts agreed that the relevant item was the anxiety that the researcher wanted to know.…”

“…), (Q8: "Are you afraid of being alone" was revised to "Are you afraid when you are alone?). As the second validity test, all revised items indicated a higher correlation coefficient ranging from 0.354 to 0.686, showing moderate correlation (Cannavan et al, 2021).…”

“…The corrected item-total correlation value determined the validity of each question item. A correlation coefficient of <0.30 indicates a weak correlation (Cannavan et al, 2021). Table 2 shows the results of the item-total correlation of the preliminary and second validity tests.…”
