The problem
Intervention: Nutritional Rangers Mobile Application providing nutritional education, personalized dietary recommendations, and monitoring features over three months
Who it was tested with: 22 mothers of stunted children aged 6 to 24 months from Kediri Regency, Indonesia, selected through purposive sampling.
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"A pre-test and post-test design was employed, involving 22 mothers of stunted children from Kediri Regency, selected through purposive sampling. The app provided nutritional education, personalized dietary recommendations, and monitoring features over a three-month period." The design measured the same group before and after the intervention, showing pre-post changes in nutrition outcomes and maternal knowledge.
Small sample size (n=22) without a comparison group; purposive sampling may introduce selection bias; three-month intervention period is relatively short for assessing sustained long-term effects on child growth and development.
