A psychometric study of positive and negative nominations and the pupil evaluation inventory.

Two peer evaluation measures, the Pupil Evaluation Inventory (PEI) and positive and negative nominations were compared in a sample of 260 children in grades 1 to 5. Stabilities of the measures were assessed over a 4-month period. In the total sample, PEI factors and negative nominations were more stable than positive nominations, and PEI Aggression and Withdrawal scores were more stable than negative nominations. PEI Aggression and Withdrawal scores were more stable in grades 3 and 5 than in grade 1, and the Likability factor was more stable in grades 2 to 5 than in grade 1. Negative nominations were most strongly correlated with the PEI Aggression factor, and positive nominations were more strongly correlated with Likability than with Aggression. Implications for the use of these nomination measures are discussed.
