Research on social withdrawal has been impeded by problems in the definitio
n of the construct and in its measurement. The purpose of this study was to
develop a behaviourally-based peer-nomination measure useful in measuring
two types of withdrawal: Inhibited/Wary and Self-Conscious/Anxious. In Stud
y I, we report the development of the measure. We examined whether this two
-factor structure would be supported by data obtained from multiple informa
nts. Data were collected from children in grades 3, 5, and 7, and their pee
rs and teachers. Intercorrelations of peer-, teacher-, and self-reports of
the Behaviour-Based Peer-Nomination measures of social withdrawal supported
the validity of the Inhibited/Wary dimension; teacher-peer agreement also
provided support for the validity of the Self-Conscious/Anxious dimension.
lit Study 2, the Behaviour-Based Peer-Nomination Measure of Social Withdraw
al was cross-validated against observed play behaviour with 120 boys and gi
rls. Results revealed some concordances between observational and peer-nomi
nation data.
