Objective: To determine the effectiveness of the Grandmother Language Intervention (GLI) by comparing the scores of grandmothers’ knowledge of grandchildren language development and grandchildren’s language development. Methods: In this randomized control trial, participants were 34 grandmother-grandchild dyads visiting well-child clinics of sub-district health promoting hospitals in 4 districts of Phayao province. There were 17 grandmother-grandchild dyads per group. The GLI was implemented in the experimental group at participant’s home in 3 sessions, with 30 - 90 minutes per session, and 2 days to 2 weeks apart. The outcome variables, grandmothers’ knowledge of language development and grandchildren’s language development, were measured 3 times at baseline (week 0), post-intervention (week 5), and follow-up (week 9). Data collection was conducted from April to August 2019. Descriptive statistics, chi-square test, Fisher’s exact, repeated measures ANOVA, and repeated measures ANCOVA were employed to analyze the data. Results: After completing the intervention, grandparents in the experimental group had statistically higher score than those in the control group (P–value < 0.05). The mean scores of grandmothers’ knowledge at post-intervention and follow-up were significantly higher than those at baseline (P-value < 0.05); while such increase was not found in the control group. In the grandchildren, their language development scores at post-intervention and follow-up between the two groups were not different (P-value > 0.05). Conclusion: The GLI improved grandmothers’ knowledge of grandchildren language development which could be beneficial in improving the child’s language development in the long run.
