Turkish-speaking dyzygotic twins (n = 21) and singletons (n = 23) were tested through a standard articulation test to observe whether their consonant articulations were related to their vocabulary sizes, recorded through CDI forms, at age 3;0. Twins were observed to lag behind their singleton peers and performed below the norm level in their production. Vocabulary size failed to predict twins’ articulation scores although it predicted the scores of the singleton group. The results suggested that articulation was not related to vocabulary size in twins. Exposure to sibling language was discussed as an alternative risk factor.

The psychometric characteristics of the Children's Depression Inventory, CDI (Kovacs, 1992) in a sample of 1705 participants (792 boys and 913 girls) and a clinical sample of 102 participants (42 boys and 60 girls) between 10 and 18 years old are presented. Reliability coefficients range, for both samples, from .82 (test) to .84 (retest) in the community sample, and .85 (test, clinical sample); test-retest reliability is .81 in the community sample. The mean scores are similar to other Spanish and English ones. Girls score higher than boys. The cut-off point that best differentiates between depressive and community participants is 19, with a sensitivity of 94.7%, a specificity of 95.6%, a positive predictive value of .90, and a negative predictive value of .98.

In order to find out whether parents and teachers report depressive symptoms in children with self-reported depression and which features are connected with sought psychiatric care, a sample of 5682 prepubertal children was assessed with the Children's Depression Inventory (CDI), the Rutter A2 scale (RA) and Rutter B2 scale (RB). In stepwise regression analysis of parent report, depressed mood, unpopularity, social withdrawal, disobedience, inattentiveness, and stealing were associated with high CDI scores. The items of the teacher report associated with high CDI scores included poor school performance, restlessness, somatic complaints, unresponsiveness, being bullied, and absenteeism from school. Although the parents and teachers readily saw and reported depressive symptoms in children, only for a small minority of children with multiple depressive symptoms had psychiatric care been sought or even considered. The symptoms associated with sought psychiatric care for depressed children were somatic (soiling, asthma) and behavioural (disobedient, restless). The results indicate that a large number of children with multiple depressive symptoms are left without necessary psychiatric assessment and help.
