RESUMO
Abstract Background Self-care in the management of systemic arterial hypertension (SAH) is crucial, and validated instruments can help researchers and health professionals to plan strategies to improve self-care in people with SAH. Objective The main objective of this study was to translate, cross-culturally adapt, and validated the Hypertension Self-Care Profile (HBP-SCP) for Brazilian Portuguese. Methods The translation and cross-cultural adaptation was performed in five phases, and the pre-final version was tested in 30 individuals, native speakers of Portuguese with a diagnosis of hypertension. The final version was administered in 100 individuals. The inclusion criteria were: diagnosis of SAH, characterized by systolic arterial blood pressure ≥ 140 mmHg and/or diastolic arterial blood pressure ≥ 90mmHg, regular use of antihypertensive medications and over 18 years of age. The present study also used two other questionnaires, previously validated for the Brazilian population, to verify the validity of the construct, the Healthy Habits Perception Questionnaire (HHPQ) and the Quality of Life in Hypertension Mini-Questionnaire (MINICHAL-BRASIL). Results During the translation and cross-cultural adaptation phase, there were no disagreements. Adequate reliability — intraclass correlation coefficient (ICC) ≥ 0.89, standard error of measurement (SEM) % ≤ 4.34, minimum detectable change (MDC) % ≤ 12.04 — and internal consistency (Cronbach's alpha ≥ 0.75) were observed. The behavior domain of HBP-SCP obtained significant correlations (p < 0.05) with the self-efficacy domain and HHPQ; the motivation domain with the self-efficacy domain; and the self-efficacy domain with the somatic manifestation domain of MINICHAL-BRASIL. No ceiling and floor effects were observed. Conclusions The Brazilian Portuguese version of the HBP-SCP has adequate psychometric properties, according to the best scientific recommendations.
RESUMO
ABSTRACT BACKGROUND: The Finnish Diabetes Risk Score (FINDRISC) is a questionnaire that was developed by Finnish researchers to track the risk of diabetes. OBJECTIVE: To translate, cross-culturally adapt and validate the FINDRISC for use in Brazilian Portuguese. DESIGN AND SETTING: Questionnaire validity study conducted at a private university. METHODS: The Brazilian version of the FINDRISC was developed through the processes of translation, back-translation, committee review and pre-testing. Test-retest reliability was measured using the intraclass correlation coefficient (ICC), kappa coefficient, standard error of measurement (SEM) and minimum detectable change (MDC). Internal consistency was measured using Cronbach's alpha. For construct validity, the total score of the FINDRISC was correlated with the Diabetes Knowledge Scale (DKN-A) and Diabetes Mellitus Risk Questionnaire (QRDM). Ceiling and floor effects were also evaluated in the present study. RESULTS: For construct validity and floor and ceiling effect measurements, a total sample of 107 participants was used. For reliability, a subsample of 51 participants out of the total sample was used. We identified adequate values for reliability (kappa ≥ 0.79 and ICC = 0.98) and internal consistency (Cronbach's alpha = 0.84). Regarding the error inherent in the FINDRISC, we found SEM = 8.02% and MDC = 22.44%. There were significant correlations between the FINDRISC and the QRDM (r = 0.686) and DKN-A (r = -0.216). No ceiling or floor effects were found. CONCLUSION: The Brazilian version of the FINDRISC has adequate psychometric properties that are in accordance with the best international recommendations.
