Comparison of the effectiveness of two intervention methods in reducing stress levels in children with autism

This study was conducted to compare the effectiveness of video modeling with that of the visual pedagogical module in reducing stress levels during dental treatment in children with autism spectrum disorders (ASD). This clinical experimental study comprised 20 children (age, 6-10 years) with ASD who had been diagnosed with ASD by a pediatrician or psychiatrist. The subjects were divided into two groups: video modeling and the PV-BDG module intervention groups (n = 10 each). Saliva was collected from the subjects before and after the interventions to measure the salivary immunoglobulin A (sIgA) levels. Data analysis was performed using the Shapiro-Wilk normality test and independent t-test to compare differences in stress reduction between the two groups. A decrease in sIgA levels was observed after the PV-BDG module intervention. The average levels of sIgA after the video modeling and visual pedagogical module interventions were-15.06 23 23.85 and 34.46 9.83. However, no significant difference in sIgA levels was noted between the two groups. Video modeling and visual pedagogical modules can effectively reduce the stress levels of children with ASD during dental care as measured by changes in the sIgA levels.
