Abstract
AIM AND METHODS: Cross-sectional data from 118 Chilean children with ASD collected during the pandemic outbreak of COVID-19 in 2020 were evaluated to analyze predictors of behavioral problem impairment. RESULTS: Forty-five percent of parents stated that their children's behavioral difficulties increased in intensity or frequency. The adjusted predictors were having a family member hospitalized with COVID-19 (OR = 4.11; 95% CI = 1.53-11.1) and parents' mental health disorders during the pandemic (OR = 2.43; 95% CI = 1.01-5.83). CONCLUSION: Potentially modifiable psychosocial factors affecting children's behavior should be considered in a possible second outbreak.
