Early predictors of parent- and self-reported perceived global psychological difficulties among adolescents: a prospective cohort study from age 3 to age 15.

Both parent and self-reports of a child's difficulties are the outcome of an accumulation of the child's psychopathology, parental distress, and family dysfunction. The results emphasize the importance of early detection of children at risk of negative developmental pathways. In clinical practice and in prevention interventions, it is important to take into account the child's individual psychopathology, parental distress, and family dysfunction.
