Authorship SCIMAGO INSTITUTIONS RANKINGS

ABSTRACT

Objective:

Semantically validate an educational technology with the caregiver of children and adolescents undergoing chemotherapy.

Method:

Methodological study, with a quantitative approach, guided by the theoretical framework of psychometry, developed between March and April 2022, with nine caregivers of children and adolescents undergoing chemotherapy. Educational technology is a digital animation film about the pediatric chemotherapy treatment process, used as a tool for health education.

Results:

In the reliability assessment, the Intraclass Correlation Coefficient was 0.936 [95%CI 0.868-0.984] with p < 0.05 and Cronbach’s alpha of 0.943, demonstrating satisfactory internal consistency. Regarding the semantic analysis, the domains related to objectives, organization, language, appearance, and motivation showed an agreement rate above 80%.

Conclusion:

Educational technology showed satisfactory rates, proving to be a valid, reliable, and important instrument to be used by caregivers of children and adolescents undergoing chemotherapy.
