Assessment of Childhood Depression: Sampling Multiple Data Sources with One Instrument
Journal of Psychoeducational Assessment
The low correspondence among reporting sources in the measurement of childhood depression is well documented. However, no effort has been made to quantify the effects of using different measures with different sources. In this research the administration of the Peer Nomination Inventory of Depression (PNID) was modified to obtain three scores: (1) each child's rating of depression as given by his/her peers; (2) each child's self-rating of depression and (3) the number of times children assigned ratings of depression to others. The Children's Depression Inventory (CDI) was administered for comparative purposes. Results suggest that differences in test items and formats can explain some, but not all, of the low correlations among reporting sources. Gender differences in the three modified PNID scores also were investigated.
