OBJECTIVE: To identify sociodemographic, child, parent, and day care provider factors at age 4 that predict Norwegian children’s service use for mental health problems at age 7.

METHOD: Two birth cohorts of 4-year-old children and their parents living in the city of Trondheim, Norway, were invited (82% consented). We successfully interviewed 995 parents among 1250 drawn to participate using the Preschool Age Psychiatric Assessment to set diagnoses and record parental burden and service use. Information concerning sociodemographics, child impairment, parental social support, and child need for mental health services according to parents, day care teacher, and health nurse were obtained.

RESULTS: Rate of service use among those with a behavioral or emotional disorder was 10.7% at age 4 and 25.2% at age 7. Behavioral disorders (odds ratio [OR] 2.6, confidence interval [CI] 1.3–5.3), but not emotional disorders, predicted service use. When adjusted for incapacity (OR 1.3, CI 1.2–1.6), disorders were no longer predictive. Incapacity, in turn, was not predictive once parental burden (OR 1.1, CI 1.0–1.1) and parents’ (OR 2.7, CI 1.0–7.9) and day care teachers’ (OR 2.1, CI 1.4–3.2) judgment of child need of help were included. Lower socioeconomic status predicted more service use over and beyond these factors (OR 3.0, CI 1.5–6.1).

CONCLUSIONS: Behavioral disorders may instigate service use if they result in impairment, and such impairment may operate via increased parental burden and parent and caregiver problem recognition. Service use may be increased through effective screening programs and ef
