“…However, the second FFQ only had 37 subjects (49.3%) in the same quartile and the level of agreement is lower than the first FFQ. Another study by Fernandez et al [37] validated a FFQ against seven-day FR. They estimated the genistein intake and compared while using the quartile classification.…”

The measurement of vitamin D nutritional status through dietary assessment is cost effective. Food frequency questionnaire (FFQ) is usually validated against food records (FR). There is no vitamin D-specific FFQ for Qatar population. The objective of this study was to develop a vitamin D-centric FFQ and validate FFQ against three-day FR for Qatar population. A quantitative FFQ based on vitamin D containing foods consumed in Qatar was developed. Vitamin D contents of foods were gathered from food labels and food composition tables from the United States Department of Agriculture. A vitamin D content database was developed for this study purpose. Dietary intakes while using FFQ and three-day FR were collected from 62 women. Vitamin D intakes from FFQ and three-day FR were validated with quartile comparison and Bland-Altman (BA) tests. BA plot showed an agreement between FFQ and three-day FR vitamin D intakes. The BA index was 3.23%, which is <5%, a commonly used standard for validation. Quartile correlation showed that ≈73% of subjects were within the same or adjacent quartile. In conclusion, an agreement was found between vitamin D intakes from FFQ and three-day FR in Qatari women. More studies are needed to validate the vitamin D-specific FFQ in Qatari population at large.

“…The purposive sampling including academics from several University campuses, without management positions, is pertinent when considering the antecedents previously presented in the theoretical framework regarding the comparison with managers' perceptions (Cardoso et al, 2013;Stensaker et al, 2011), and potential geographic differences. A purposive, convenience research sample, as a complementary sequential stage of a measure validation, has been previously reported by Milne, Creedy, and West (2016) and Fernandez, Omar, and Husain (2013) with positive results, and even in the study of Carpio et al (1999) considering Chilean and Canadian samples.…”

Las políticas de mejoramiento de la calidad ocupan un lugar central en la educación superior y representan requisitos importantes para las instituciones educativas en una economía globalizada, en tanto que la legitimidad de los procesos relacionados con la calidad se ve reforzada por la participación de la comunidad académica. En consecuencia, el propósito de este estudio es desarrollar y validar una escala en castellano destinada a evaluar las percepciones sobre el proceso de acreditación y la gestión de la calidad en las Instituciones de Educación Superior. En base a hallazgos anteriores, y utilizando un diseño transversal en un solo momento en el tiempo, se encuestaron 339 académicos en cuatro ciudades académicas importantes de Chile. Utilizando el modelado de ecuaciones estructurales, se encontraron dos soluciones con índices de ajuste adecuados: una solución de cuatro factores que incluye Relevancia institucional de la Acreditación, Objetividad de la evaluación de acreditación, Relevancia de la Unidad de Calidad Interna para la acreditación, Valor de la acreditación para el sistema educativo, como principales constructos, y una solución de seis factores, que incluyó dos constructos adicionales: el Valor de la gestión continua de la Calidad y el Valor de la participación de los Estudiantes.El cuestionario desarrollado en nuestra investigación, permite a las instituciones de educación superior evaluar y cuantificar objetivamente los beneficios de la gestión de la calidad y la acreditación. Sus resultados son particularmente pertinentes para países con el castellano como lengua oficial considerando la importancia de la internacionalización de la educación superior.

“…Apart from several studies suggesting the validity of FFQ in the assessments of phytoestrogen intake of Asian [61][62][63], and even other populations [64,65], limited information put efforts on flavonol intakes validity [21,66], particularly based on biomarkers. In addition to Allium (onion and spring onion), cruciferous and Apiaceous (vegetables) and fruit intakes correlated highly with querctin and kaemferol intakes, studies in Asian population showed the major source of flavonols (and flavones) in fruits (apple and citrus) and vegetables (potato and celery) [66,67], and Western population suggested beverages as the sources of dietary polyphenols [30].…”
