Research paper thumbnail of Teacher Reports of Peer Aggression in Preschool: its Relationship to DSM-IV Externalizing Symptoms

Method: Subjects were 1,104 children, 3-to-5-year-olds attending rural and urban pre-schools classes. Teachers completed the Peer Conflict Scale (PCS) to inform about direct physical and verbal aggression, object aggression and symbolic aggression and the questionnaire on psychopathology ECI-4. Results: 6.6% (n= 73) had at least one positive item on the PCS. This percentage dropped to 2.6% (n= 29) if we take into account a minimum of three positive items. Physical direct aggression was the more prevalent type of aggressive behavior, followed by verbal aggression, object aggression and symbolic aggression. Significant differences by gender and age were found. Peer aggression was associated with male gender from three years of age. Physical, object and verbal aggressive behavior was linked...

We have created the Behavioral Inhibition Scale for Children Aged 3 to 6 (BIS 3-6) to detect this trait early. Parents and teachers of 365 preschoolers completed different versions of the BIS 3-6 and provided measures of psychopathology. Both versions are structured into 1 factor that explains over 40% of total variability and displays excellent internal consistency (α = .95). The moderate correlations with measures of internalizing symptoms (r = .50) and nonexistent correlations with externalizing measures suggest adequate convergent and discriminant validity. A new scoring system is proposed.

The whole population of children between 3 and 6 years attending preschool nurseries in three areas (one urban, one rural and one suburban) in Spain (n = 1,427) were contacted. Selection was by a two-stage procedure. At stage I, the ESDM 3-6, a screening measure for preschool depression, was used to identify a sample for more intensive interviewing. Sensitivity and specificity of the cutoff point of the ESDM 3-6 had been previously tested in a pilot study (n = 229). During the first stage, 222 preschool children (15.6%) were found to be probable depressives, because they scored 27 or more, the cutoff used. At stage II, the children were interviewed and diagnosed by the consensus of two clinicians, blind to the ESDM 3-6 results. DSM-IV diagnostic criteria were used to define caseness. A total of 16 children (1.12%) met the MDD criteria. The prevalence by areas was urban 0.87%, rural 0.88%, suburban 1.43%. Sex distribution prevalence was 1:1. This study is a contribution to the scarce epidemiology of preschool depression in the community.
