This study presents the results of the validation process of two data collection instruments on the inclusion of grandparent- grandchild relationships in Primary Education. Two ad hoc questionnaires were designed for the families of the students and the teachers (CUABU-F and CUMEABU-D) with the aim of assessing their conceptions of the roles and profiles of grandparenting and their influence on the development of school children's identity. From a quantitative approach and with an analytical design, the content validity was estimated through expert judgment, the internal consistency (Cronbach's Alpha model) and the construct validity (Principal Component analysis) of both instruments. An instrumental research design that consisted of two phases was used. In the first one, seven experts participated, who judged the questionnaires based on a scale developed for this purpose. The second phase consisted of a pilot study where information was collected from 110 teachers and 72 parents of Year 5 students in the Region of Murcia. The results showed that the instruments had content validity in terms of their pertinence, coherence, sufficiency, adequacy, relevance and clarity. Furthermore, both instruments revealed fairly high reliability and adequate construct validity. These questionnaires allowed for the diagnostic evaluation of a project that promotes grandparent-grandchild relationships in Primary Education classrooms. [ABSTRACT FROM AUTHOR]

Objective: This research was designed to determine the validity and reliability of the Zarit Burden Interview, specifically the 22-item Spanish version, as an instrument to measure the burden of care perceived by family caregivers of patients in Colombia with chronic diseases. Materials and Methods: A cross-sectional study of 652 family caregivers of patients with chronic diseases who reside in five regions of Colombia was conducted to establish construct validity, with a factor analysis and internal consistency reliability measured by determining the Cronbach's alpha value. Result: In terms of construct validity, the study reports the total loading, based on free association of a varimax rotation, and in the dimensions that include interpersonal burden, impact of care, and skills and expectations about care. The factor loadings pertain to the items introduced to measure each of the proposed dimensions. Conclusion: The results showed the 22-item Spanish version of the Zarit Burden Interview is an instrument that can be applied and understood easily in a Colombian population with different educational, socio-economic and cultural levels. It also proved to be valid and reliable for assessing the burden of care perceived by family caregivers of patients with chronic diseases. [ABSTRACT FROM AUTHOR]
