Risk factors associated with higher scores in internalizing and externalizing behaviors in Chilean preschoolers

Abstract

AbstractEarly detection of behavioral disorders in children is necessary for intervention. Available data show a high prevalence of child and adolescent psychiatric disorders in Chile (22.5%), but behavioral problems in younger children have not been evaluated. This work assesses behavioral disorders in preschoolers and their association with sociodemographic variables of the family and the child. The data was collected during the impact assessment of the Biopsychosocial Development Support Program “Chile Crece Contigo”, using a multistage and representative random sample of 1377 preschoolers, aged between 30 and 48 months, who attended public health services. Homes were visited to apply a questionnaire and the Child Behavior Checklist (CBCL, 1.5–5 years). Results: Multivariable regression model for total raw scores shows that child's age, the number of chronic diseases in the child, and history of exposure to mother's alcohol consumption in pregnancy, remain significant when adjusted for all variables included (R2 of 17.8% and η2 of .19 (95% CI: .14–.22)). In externalizing and internalizing explanatory models, child's chronic diseases and a higher score of authoritarian beliefs about parenting show the two largest effect sizes. These results add to the evidence of urgent problems in preschool mental health.
