ABSTRACT
Objetivo: Determinar la validez de constructo y confiabilidad del «Cuestionario para medir la adherencia al tratamiento de los pacientes con enfermedad cardiovascular¼. Métodos: Estudio de tipo psicométrico. La muestra seleccionada fue de 250 pacientes con diagnóstico de enfermedad cardiovascular asistentes a una institución hospitalaria de tercer nivel de atención en la ciudad de Neiva (Colombia) en el primer semestre de 2016. Se desarrollaron cronológicamente diferentes fases investigativas: análisis del concepto, exploración y confirmación del constructo. Resultados: A través del análisis del concepto se estableció como teoría de soporte la «autoeficacia¼ con sus tres componentes teóricos, seis dimensiones temáticas transversales y los atributos esenciales de la adherencia al tratamiento, los cuales se evidenciaron en la reformulación de los 38 ítems de la versión final del instrumento. La muestra en su mayoría estuvo conformada por personas mayores de 60 años, factor de riesgo predominante de hipertensión arterial y diagnóstico médico más frecuente de enfermedad coronaria. El análisis factorial exploratorio reportó seis factores con una varianza total explicada de 61.83%. La matriz multirasgo-multimétodo demostró altas correlaciones intradimensión, lo cual evidenció la validez convergente del instrumento. El alfa de Cronbach obtenido fue de 0.92 para la escala total y dimensional por encima de 0.80. Conclusiones: La versión actual del instrumento es válida y homogénea para la medición de la adherencia al tratamiento de los pacientes con enfermedad cardiovascular; útil para la investigación y la práctica clínica.
Abstract Objective: To determine the construct validity and reliability of the ''Questionnaire to assess the adherence to treatment in patients with cardiovascular disease''. Methods: This is a psychometric study. The selected sample included 250 patients diagnosed with cardiovascular disease and treated in a third-level-attention hospital institution in Neiva, Colombia during the firrst semester of 2016. The diverse research stages were chronologically developed as concept analysis, exploration, and construct confirmation. Results: Through the concept analysis process, ''self-efficacy'' was established as a supporting theory with three theoretical components, six transversal thematic dimensions, and the essential attributes to the adherence to treatment, which were evidenced in the reformulation of the 38 ítems of the final version of the instrument. The sample was mainly constituted by persons older than 60 of age, which is a risk factor for hypertension and coronary problems. The exploratory factor analysis yielded 6 factors explaining 61.83% of the total variance. The multi-method and multi-treatment matrix demonstrated high intra-dimension correlations, and thus, the convergent validity of the instrument was evidenced. Cronbach alpha was 0.92 for the total scale, and 0.80 for the scale dimensions. Conclusions: The present version of the instrument is valid and homogenous for the assessment of adherence to treatment in patients suffering from cardiovascular disease, and it is useful for the clinical practice and research.

ABSTRACT Purpose proper chewing and swallowing functions have great importance in general health, since it potentially affects food’s digestion and the subject’s nutritional status. The aim was to assess the validity and reliability of the self-applied Quality of Masticatory Function Questionnaire (QMFQ) in a convenience (non-referred) sample of Brazilian adolescents divided into three groups: control (n=57), dental caries (n=51) and malocclusion (n=54). Methods caries and malocclusion were evaluated using DMF-S index (number of decayed, missing and filled primary and permanent surfaces) and Index of Orthodontic Treatment Need, respectively. The QMFQ comprises 26 items regarding frequency and intensity of chewing problems with five domains: Food-Mastication, Habits, Meat, Fruits and Vegetables. Data were submitted to descriptive statistics, Kolmogorov-Smirnov and Chi-square tests. Psychometric evaluation included measures of reliability (internal consistency - Cronbach's alpha and matrix of correlation) and discriminant validity (Kruskal-Wallis/Dunn post-test). Results the instrument showed satisfactory internal consistency, with significant positive correlations between the domains scores except between Habits and Vegetables. Total scale Cronbach's alpha coefficient was 0.87 and the coefficient did not increase significantly with the removal of each domain. Significant differences were found between controls and caries group in Food-Mastication, Meat and Fruits scores. Caries group also showed higher median values in Food-Mastication and Fruits than the malocclusion group. Conclusion the Quality of Masticatory Function Questionnaire showed acceptable properties regarding internal consistency, reliability, and discriminant validity in evaluating the impact of caries on the perception of the masticatory function quality of Brazilian adolescents.

Introducción: El Gross Motor Function Measure, diseñado en 1990, es un test específico para la valoración de la función motora gruesa principalmente en niños con parálisis cerebral. Objetivo: Presentar la validez de apariencia del test en su versión 88, centrada en el componente transcultural. Materiales y métodos: Estudio descriptivo, donde se envió la adaptación española, publicada en 2009, a tres expertos, para posteriormente, identificar el índice de aceptabilidad. Resultados: El índice de aceptación global es de 0,85 considerado como bueno, observándose un menor índice en la dimensión B y mayor en la D, con un acuerdo del 100% en 66,66% de los ítems a estudio. Conclusiones: Se presenta la validación transcultural del test con un buen índice de aceptabilidad para la práctica clínica.
Introduction: The Gross Motor Function Measure, designed in 1990, is a specific test for the assessment of gross motor function used mainly in children with cerebral palsy. The aim of this paper is to present the face validity of the test in its 88 version, focusing on cross-cultural component. Materials and methods: A descriptive study, where the Spanish adaptation published in 2009 was sent to three experts, to subsequently identify the acceptability index. Results: the overall acceptance rate of 0.85 is considered good, showing a lower rate on the dimension B and higher in D, with 100% agreement in 66.66% of the items studied. Conclusions: The cultural validation of the test is presented with a good index of acceptability for clinical practice.
