Desenvolvimento e validação de um protótipo de aplicativo para plataforma móvel para promoção da saúde de gestantes

Abstract

Mobile apps have been used as a lightweight hard technology tool for health promotion. Apps for guidance in pregnancy can be useful as a complementary way to access information. This study developed and validated a mobile platform app for pregnant women Health Promotion. The methodological, technological and quantitative-qualitative study was carried out in three phases: situational diagnosis (scientific production via Bireme and technological via Google Play); Gestar prototype development (via Horst Rittel linear model and Design Thinking method using the Adobe XD tool) and validation by midwifery and computer judges. The group of midwifery judges, composed of health professionals (nurses and physiotherapists) with average working time with educational media of 4.8 years (± 3.7 years) and teaching / research 8.0 ± (6.2 years), validated content and appearance. Computer judges had a background in computing and digital media 7.6 years (± 4.7 years) and evaluated usability. Online forms were used via Google Forms (sociodemographic, appearance validation, content and usability). Data collection was performed after approval by the Comitê de Ética em Pesquisa of the Universidade Federal do Ceará (no. 3,262,855). The data was exported in Microsoft Office Excel® 2010 for Windows. IVC analyzes were performed using SPSS® version 20® software. The scientific production consisted of 10 studies with low methodological rigor and none presented data related to the validation phases, although they evaluated usability. In the technological production were found 250 applications available, 161 paid and 89 free, in which the average star was 4.2, and the final sample of 13 apps. The available apps provide fragmented and sparse information. The prototype Gestar app was developed and its content is organized into Main Menu and Submenus. For the first use, you must perform the registration. After registration and every time you open the app, the pregnant woman will have access to the Main Menu called "Agenda" (guidance on vaccination, gestational calculations, reminders, notes and contraction counter). At the bottom of the screen you can choose "Prenatal", "Where I go", "Childbirth", "Tip and doubts" and "Postpartum". In the validation, it was observed that, in the appearance category, the average of the proportions of the items considered relevant was 47% and the average of the values of the separately calculated items 0.47 (± 0.09), with excellent agreement (IVC = 0.93). In the content category, the average of the proportions of the items considered relevant was 34% and the average of the separately calculated item values 0.34 (± 0.20) with good agreement (IVC= 0.68). The average proportion of the items considered relevant in the usability category was 28.10% and the average of the separately calculated item values was 0.31 (± 0.11) with good agreement (CVI = 0.62).
