Psychometric performance of the brazilian version of the Mini-cuestionario de calidad de vida en la hipertensión arterial (MINICHAL)

Abstract

This study aimed to evaluate the feasibility, acceptability, ceiling and floor effects, reliability, and convergent construct validity of the Brazilian version of the Mini Cuestionario de Calidad de Vida en la Hipertensión Arterial (MINICHAL). The study included 200 hypertensive outpatients in a university hospital and a primary healthcare unit. The MINICHAL was applied in 3.0 (± 1.0) minutes with 100% of the items answered. A "ceiling effect" was observed in both dimensions and in the total score, as well as evidence of measurement stability (ICC=0.74). The convergent validity was confirmed by significant positive correlations between similar dimensions of the MINICHAL and the SF-36, and significant negative correlations with the Minnesota Living with Heart Failure Questionnaire -MLHFQ, however, correlations between dissimilar constructs were also observed. It was concluded that the Brazilian version of the MINICHAL presents evidence of reliability and validity when applied to hypertensive outpatients. Desempeño psicométrico de la versión brasileña del Minicuestionario de calidad de vida en la hipertensión arterial (MINICHAL)Este estudio tuvo como objetivo evaluar la practicidad, la aceptabilidad, los efectos techo y suelo, la confiabilidad y la validez de constructo convergente de la versión brasileña del Minicuestionario de Calidad de Vida de la Hipertensión Arterial -MINICHAL. Participaron del estudio 200 pacientes hipertensos en seguimiento en ambulatorio, en hospital universitario y en Unidad Básica de Salud. El MINICHAL fue aplicado en 3,0 (±1,0) minutos, con 100% de los ítems respondidos. Fue observado "efecto techo" en ambas dimensiones y puntaje total, así como evidencias de estabilidad de la medida (CCI=0,74).La validez convergente fue confirmada por correlaciones significativas positivas entre dimensiones similares del MINICHAL y del SF-36, y por correlaciones significativas negativas con el Minnesota Living with Heart Failure Questionnaire -MLHFQ, a pesar de que correlaciones entre constructos no similares hubiesen sido observadas. Se concluye que la versión brasileña del MINICHAL presenta evidencia de confiabilidad y validez cuando aplicada en hipertensos en seguimiento en ambulatorio.

Prevalence of sickle cell trait in dialysis patients

“…The observed predominance of hypertension was higher in comparison with other surveys published in Brazil, which included a population basis from the South and Southeast and reported prevalences of 22.3% and 43.9%, respectively (6) . The sample revealed 3.6% of patients with sickle cell trait, including two males and two females.…”

Escala para o cuidado apoiado na atenção primária: um estudo metodológico

“…Depression and anxiety are commonly associated with chronic diseases, and in this case they may negatively affect cognitive focus, energy and motivation, as well as the willingness and competence to follow treatment (14)(15) . When comparing individuals with mild symptoms of depression and anxiety (14) , a tendency for smoking, physical, sexual and sleep disturbances can be noticed, but these participants are considered to be in regular health.…”

Item Response Theory Analysis of the Hospitalized Patients Spiritual Needs Questionnaire

“…The HPSNQ design and validation process involved: (1) early design of the questionnaire using 16 interviews with hospitalized patients in general hospital settings based on conventional content analysis of Zhang & Wildemuth (2009) [15], as well as the related literature review; (2) assessing the face and content validity of the tool, (3) pilot test to investigate the psychometric properties, accompanied by essential revisions of the scale, (4) administering the modified tool with a more comprehensive sample to analyze psychometric properties more by exploratory and con rmatory factor analysis of HPSNQ, and (5) establishing convergent validity by estimating score correlations with the cancer patients' spiritual needs questionnaire that was validated beforehand. Overall, the HPSNQ demonstrated acceptable psychometric attributes.…”

“…In the CTT, the analyses is done according to the behavior of the whole set of items of the instrument, illustrating the analyses at the test level. When utilizing a tool in clinical settings or in an investigation, we should have enough data about its psychometric properties, limitations, and strengths, so that we can interpret the results obtained with the tool thoroughly [16]. In this regard, IRT provides a rich source of knowledge about the latent structures.…”
