Translation, Cross-Cultural Adaptation, and Validation of the Hypertension Self-Care Profile (HBP-SCP) for the Brazilian Population

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.

Identificação de elementos de vulnerabilidade da placa coronária por tomografia computadorizada e ressonância magnética / Elements identification of coronary plaque vulnerability for computadorized tomograph and magnetic ressonance

Há cerca de dez anos, foi introduzido o conceito de placa coronária instável como aquela que, independentemente do grau de obstrução que promova sobre a luz arterial, se relaciona com a incidência de eventos coronários, tais como angina instável, infarto do miocárdio com ou sem onda Q e morte súbita. Este assunto tem sido alvo de intensa pesquisa, e um dos aspectos que desperta maior interesse é a caracterização anatômica destas placas. Alguns autores têm proposto a realização de exames invasivos, tais como ultra-som intracoronário, medida da temperatura da placa e até tomografia computadorizada de coerência óptica. Todavia, estes exames proporcionam desconforto aos pacientes e apresentam resultados ainda conflitantes...
