Nephrotic syndrome is a medical condition where the kidneys release substantial amounts of protein into the urine, resulting in various issues such as tissue swelling and an increased susceptibility to infections. Emphasizing the importance of adequate nutrition and symptom monitoring is crucial in managing urine protein levels and mitigating associated complications.

The purpose of this study was to boost self-efficacy through a computer game-based program, aiding pediatric patients with Nephrotic syndrome in the adoption of healthy eating habits and efficient management of urine protein levels.

This study was Quasi-experimental Research. Two group pre-test post-test with repeated measures design. Forty school-age children diagnosed with nephrotic syndrome were randomly allocated into two groups, with the participants distributed between an experimental group and a control group, each comprising 20 individuals. The experimental group underwent a program that aimed to enhance self-efficacy through computer games for a duration of 5 weeks, whereas the control group received regular nursing care. Information was gathered through personal record forms, urine protein assessments with test strips, dietary behavior surveys for school-age children with nephrotic symptoms, and self-efficacy surveys related to dietary behavior within the same group. The data underwent analysis using repeated measures analysis of variance. Statistical significance was defined as p < .05.

Inclusion Criteria:

• Confirmation of nephrotic syndrome diagnosis by a physician and continuous hospital treatment for a minimum of 3 months.
• Presence of proteinuria levels at 1+ or higher during morning awakening or a urine protein quantity exceeding 30 mg/dL within the past 6 months (verified through medical records).
• Proficient communication skills in the Thai language.
• Ownership of a telephone or device suitable for gaming and internet connectivity.
• Willingness and cooperation from both the family and the child to actively participate in the research.
• Discontinuation of steroid medication by school-age patients.

Exclusion Criteria:

• involve symptoms indicative of a critical condition, such as entering a crisis or severe complications like heart failure or pleural effusion.
• school-age patients whose treatment plan has been modified by a physician, including the use of injectable medication instead of oral drugs or those receiving treatment in an inpatient setting.
