Peer Nomination Inventory of Depression: Characteristics in a Spanish sample

The Peer Nomination Inventory of Depression (PNID) was answered by 1,121 children from Barcelona in the fourth year of grammar school and by their teachers (n=36) to analyze this questionnaire in a Spanish sample. The results indicated (1) high internal consistency; (2) discriminative power between depressed and nondepressed; (3) low concurrent validity; (4) convergent and discriminant validity; (5) a two-factor structure; and (6) that two discriminant functions could differentiate between depressed, dysthymic, and nondepressed subjects. The teacher's responses showed (1) moderate internal consistency; (2) discriminative power between depressed and nondepressed groups; (3) moderate concurrent validity; (4) and that two discriminant functions could differentiate between the diagnostic groups. The importance of the information given by the teacher to help detect severe depressive problems was pointed out. © 1990 Plenum Publishing Corporation.
