RESUMEN
ABSTRACT Objective: To describe the dynamic self-determination of self-care (DSDoSC) and positive deviance (PD) models in changing stunting prevention behavior. Material and Methods: This research is a quasi-experimental study with a sample of 90 mothers taken by purposive sampling. Thirty mothers were given the DSDoSC intervention, 30 were given the PD intervention, and another 30 were in the control group. This research was conducted in July - October 2019. The variables studied were feeding behavior, nurturing behavior, personal hygiene behavior, environmental cleanliness and air sanitation, and behavior seeking health services. To analyze the difference in mother behaviour before and after test, we used Paired t-test. Analysis of Variance (MANOVA) was used to analyze the difference of mother behaviour among groups. The level of significance was p<0.05. Results: The PWD group showed that eating behavior, parenting behavior, personal hygiene behavior, environmental hygiene and water sanitation, and behavior seeking health services had significant numbers. In the DSDoSC group, eating behavior, parenting behavior, environmental hygiene, water sanitation and health service-seeking behavior were significantly (p<0.05). The results of the Manova test showed that there was an effect of PD and DSDoSC on stunting prevention behavior. Conclusion: Self-dynamic for self-care model and the positive deviance model both can change a mother's behavior for the better in feeding, parenting, environmental hygiene, and water sanitation, seeking health services, but not changing behavior about personal hygiene behavior.
