Validation of Educational Video to Promote Self-Efficacy in Preventing Childhood Diarrhea

Abstract

The aim of this study was to evaluate and to validate an educational video to promote maternal self-efficacy in preventing childhood diarrhea with women assisted in a health unit. Validation study, developed with 17 mothers whose children were under five years old, was analyzed on scenes of an educational video according to the validity of appearance (clarity/comprehension) and of content (relevance). The scenes were considered clear and comprehensive with a perceptual above 70% and with an average of 96.9% of agreement. Regarding the relevance, the agreement was maintained between 94% and 100%, however only scenes 03 and 13 presented 76.6% and 70.6% of agreement respectively. Global Content Validation Index of the educational video scenes was 0.97 meaning an excellent level of agreement among mothers. The video showed to be a valid and a trustworthy material to promote maternal self-efficacy in preventing childhood diarrhea. Therefore, it is important that the material is disseminated in other health services so that other mothers may have contact with the same, providing greater reliability of the material.

Validation of primer for promoting maternal self-efficacy in preventing childhood diarrhea

“…Results of previous researches, which served as a basis for elaborating the survey on the primary care for promoting maternal self-efficacy in preventing childhood diarrhea, showed that mothers presented similar characteristics to those from this study, such as low education and families consisting of more than three members (7,12) . These aspects reflect the reality of part of the Brazilian population, so that the educational primer emerges as a valid and reliable material both for economically disadvantaged families and those with greater socioeconomic conditions, since the primer is understandable to the lowest stratum of the population, it will also be for the highest.…”

“…We also highlight the fact that some suggestions have not been accepted also occurred in other studies, being necessary to assess whether the mothers' suggestions are relevant to the purpose of the educational material (12) .…”

“…Thereby, the validation by the target audience allows the written material to express ideas clearly, ensuring the understanding and avoiding dubious interpretations that may influence the development of concepts and/or inappropriate actions (10) . For this reason, national and international researches have carried out, in the process of elaborating educational materials, the validation by the target population, so that the material can be considered suitable for application in daily life (12,(20)(21)(22) . Therefore, it is appropriate to point out that educational technologies can assist in nursing care and, in this case, reduce the rates of childhood diarrhea by promoting the empowerment of mothers (12) .…”

“…We follow the recommendations of authors who recommend 25 to 50 subjects to validate technologies/ tools (13) . We highlight that the odd number of subjects was used to avoid draws on the answers and dubious questions (12) .…”

“…Therefore, the validation of the primer by the target population is important because it makes it possible to check what was not understood and what must be added or enhanced, allowing to perceive any discrepancy between the exposed in the material and what was understood by the population (12) . Recognizing the need for validation of the primer by the target population, we opted in this study by the design and content factors to assess the clarity of the material and the understanding by the public who will use it.…”
