The persistence of psychiatric deviance from the age of 8 to the age of 15 years.

Background: Earlier research has shown that psychiatric problems in children tend to persist over years. This investigation assessed the persistence of psychiatric deviance among children over a 7-year period from the age of 8 to the age of 15 years. We also explored the relationship between problems leading to special attention at the well-baby clinics before school age and future psychiatric deviance.

Psychiatric disorders, performance level at school and special education at early elementary school age.

We assessed the relationship between psychological deviance and performance level at school among 8-year-old children. The use of special education among children with psychiatric disorders was also studied. In Stage 1, 5813 children were studied using the Rutter Parent Questionnaire (RA2), the Rutter Teacher Questionnaire (RB2) and the Children's Depression Inventory (CDI).

Children's behavioural/emotional problems: a comparison of parents' and teachers' reports for elementary school-aged children.

This study assessed the agreement between parents and teachers concerning behavioural/emotional symptoms of children. 5671 children born in 1981 (mean age 8.5 years at the time of study) were studied using the Rutter Parent Questionnaire (RA2) and the Rutter Teacher Questionnaire (RB2).

Psychiatric disorders in 8-9-year-old children based on a diagnostic interview with the parents.

Using three questionnaires, the Rutter Parent Questionnaire (RA2), The Rutter Teacher Questionnaire (RB2) and the Children's Depression Inventory (CDI), we screened 8-9-year-old children representing a total annual birth cohort (N = 60007) in Finland. In a second stage we interviewed the parents of 119 screen negative, and 316 screen positive children by using a structured parent interview. At the population level the overall prevalence rate for psychiatric disturbance was 21.

Behavioural and emotional symptoms in 8-9-year-old children.

We present epidemiological data from a multi-centre study on psychiatric symptoms among 6017 8-9-year-old children representing a total annual birth cohort (N = 60007) in Finland. The results are based on three questionnaires: the Rutter Parent Scale (RA2), the Rutter Teacher Scale (RB2), the Children's Depression Inventory (CDI). The proportion of children that scored above the cutoff points, indicating probable psychiatric disturbance, were 11.
