Objectives: To describe the process of production and validation of care-educational technology (CET) on video to support home care for children with gastrostomy. Methods: Methodological research to produce and validate CET in video. An integrative review was carried out followed by the construction of the script, to determine the content and structure of the technology. The validation process took place in two stages: content validation (15 expert judges) and technical validation (05 family/caregiver judges), between September 2021 and February 2022. In this process, a Likert scale was used, with three domains: objective; structure and presentation; relevance. To avoid subjective biases, the Intraclass Correlation Coefficient (ICC) was calculated, and the items with ICC≥ 80% were maintained. Results: Video was produced with 12 minutes, which develops in two axes: knowing more about gastrostomy and home care. It includes guidelines such as peristomal skin care, food and medicine supply, prevention and management of problems related to gastrostomy. It obtained ICC≥ 80% in all evaluative items, in the two validation phases. Conclusion: The CET produced and validated allows to support the care of parents to children with GTT at home, facilitating the acquisition of technical knowledge and reducing the risks to the child and tensions in the family.
