Defined and tested repressive defense style to determine if this const
ruct was applicable to children. Eighty-three 10- to 15-year-old child
ren with asthma were categorized as repressors or nonrepressors using
the Marlowe-Crowne Social Desirability Scale, the Revised Children's M
anifest Anxiety Scale, and the Anger Expression Scale. About one third
of the children were classified as repressors. There was high concord
ance (74% to 85%) between methods of classifying repressors using ange
r or anxiety as the negative affect presumed to be repressed. In addit
ion, a high concordance rate across time was found in a subsample. Sex
differences on the Child Behavior Checklist-Parent Form were also fou
nd to relate to repressor or non-repressor classification. These data
suggest that the effects of repression on self-report data should be c
onsidered in clinical research.
