The peer preference test as a measure of reward value: Item analysis,cross-validation,concurrent validation,and replication

Thirty-six preschoolers were administered and retested on a 15-item Peer Preference Test designed to measure the reward value of peers for each child. Test-retest reliability was .88, and after item analyses, 12 items were maintained in the test. The revised test was then administered to 29 other preschoolers. Test-retest reliability was. 77, and item analyses indicated that each item made a significant contribution to the overall test. Concurrent validation of the test was demonstrated using both a picture sociometric and a behavioral measure. In addition, the Evers-Pasquale and Sherman (1975) study was replicated, using 10 preschool social isolates.This article is based on the doctoral dissertation of the author.
