Dissociation : Vol. 5, No. 2, p. 091-097 : The Children’s Perceptual Alteration Scale (CPAS): a measure of children’s dissociation
MetadataShow full item record
The Children's Perceptual Alteration Scale (CPAS) was developed as a standardized, self-report measure of children's dissociative experiences. Fifty-three children between the ages of eight and twelve completed the CPAS. This included 21 children (17 boys and 4 girls) seen for psychological evaluation or treatment and 32 children (20 girls and 12 boys) in the normal group. Parents of the children in the clinical group completed the Achenbach Child Behavior Checklist and the Eyberg Child Behavior Inventory. Children in the clinical group scored higher on the CPAS than did those in the normal group. Total CPAS score was also found to correlate significantly with Eyberg Intensity, and the Obsessive-Compulsive and Aggressive scales of the CBC. Split-half reliability of the CPAS was good (r = .75, p < .001). The CPAS appears to be a valid measure of children's dissociative experiences and may be useful in the study of normal development and childhood psychopathology.
