Effects of online social media on improving mothers’ behaviors towards preventing their children’s otitis media based on the PRECED model: a randomized educational intervention trial

BACKGROUND: Otitis media is one of the most common diseases in children, especially those under 2 years of age. This study aimed to investigate the effect of educational intervention based on the PRECEDE model on mothers’ preventive behaviors of middle ear infections in infants. METHODS: This study was conducted as an educational randomized controlled trial on 88 mothers with infants referred to health centers in Arak, Iran. Sampling from September 2021 to February 2022 selected trough stratified random sampling who were assigned to two groups of experimental = 44 and control = 44. The data collection tool was a reliable and valid questionnaire that included demographic information, constructs of PRECEDE model regarding otitis media, and preventive behaviors. The experimental group received 4 training sessions (each session 60 min) through WhatsApp social network. Information was collected through an online questionnaire before and 3 months after the educational intervention from both groups. Data analysis was also performed with SPSS version 23. RESULTS: Before the educational intervention there was no significant difference between the experimental and control groups in the otitis media preventive behaviors and structures of PRECEDE model (p > 0.05). After the educational intervention, in the experimental group the average score of knowledge from 0.49 to 0.81, attitude from 4.01 to 4.58, enabling factors from 0.72 to 0.85, reinforcing factors from 3.31 to 3.91 and behavior from 3.25 to 3.66 increased significantly (p < 0.001). CONCLUSIONS: PRECEDE-based education with controlling, monitoring and follow-up during the program was effective in promoting the preventive behaviors of otitis media. Therefore, due to the side effects of otitis media, especially in vulnerable periods such as childhood, it is recommended that trainings based on this model be carried out in other health care centers and clinics in order to maintain children health.
