Design and subjects of a Finnish epidemiological study on psychiatric disorders in childhood.

In an epidemiological multi-centre study, parents filled in the Rutter Parent Questionnaire (RA2) and teachers filled in the Rutter Teacher Questionnaire (RB2) for almost 6000 children. The children filled in the Children's Depression Inventory (CDI). The subjects well represented the entire population of 8-9-year-old children in Finland. The material and design of the study as well as the basic demographic characteristics are presented.

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 11.2% for the RA2, 13.9% for the RB2 and 6.9% for the CDI. Twenty-four percent of the subjects scored above the cutoff point on at least one of the questionnaires. Low family social status and disrupted family relations correlated strongly with high rates of symptoms in the children.

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 21.8%, higher among boys (29.8%) than among girls (12.8%). Nine percent of the children were in urgent need of treatment and, in addition, 25% were in need of assessment. The prevalence of different levels of disturbance was: reactive 9.5%; neurotic 18.4%; borderline 3.1%; and other severe disorders 2.3%. The prevalence of different diagnostic groups were: anxiety disorder 5.2%; depressive disorder 6.2%; specific fears 2.4%; defiant and conduct disorder 4.7%; and attention-deficit hyperactivity-disorder 7.1%. The prevalence for the most common single first Axis-I DSM-III-R diagnoses were: attention-deficit hyperactivity-disorder 7%; dysthymia 4.6%; adjustment disorder with mixed disturbance of emotion and conduct 3.4%; oppositional defiant disorder 2.7%; specific fear 1.7%; anxiety disorder 1.5%; enuresis nocturnal 1.5%; and depression 1.4%. Only 3.1% of the children had visited health professionals for psychiatric problems during the previous three months. Only a minority of the children with psychiatric disturbances had ever consulted health professionals for their problems. Of all the children, 7.5% had a severe psychiatric disturbance that had lasted for more than 3 years.

Behavioural/emotional symptoms among 8-9-year-old children with somatic symptoms or illnesses as reported by their teacher.

The aim of this study was to assess children's behavioural/emotional symptoms at school and to compare these symptoms of somatically healthy children with those of children with somatic illnesses or symptoms. The Rutter Teacher Questionnaire (RB2) was used for measuring psychiatric symptoms in 5813 children aged 8-9 years. The parents reported the somatic symptoms and illnesses of their children during the previous 12 months. One hundred and sixty one children had a marked or serious chronic illness, 292 had a mild chronic illness, and 92 had one or several symptoms. The findings suggest that boys with a marked or serious chronic somatic illness are prone to manifest psychiatric symptoms in their interactions with peers and teachers at school and that boys with a mild chronic illness have less psychiatric symptoms than healthy boys.

Teacher-rated psychiatric problems in 8-year-old children and parental quality of previous day-care.

In this study behavioural/emotional problems in 95 8-year-old schoolchildren were assessed by using the Rutter Parent Questionnaire (RB2) for teachers and related to earlier day-care periods. A relatively low proportion of behavioural/emotional problems was found among those children whose parents reported only moderate dissatisfaction with the first day-care period. Behavioural/emotional problems were associated with high numbers of day-care periods and short day-care periods. The proportion of problems was high among children with a moderate mean length of periods as compared with those with no day-care short periods or very long periods. The differences in behavioural/emotional problems were related to the degree of parental satisfaction with the quality, as well as to the continuity of day-care. However, the results of logistic regression analysis found no significant associations related to stability when the background factors were controlled for. These results may reflect the consequences of continuity versus discontinuity in the relationships between children, parents and caregivers.
