Jm. Stokes et al., The relationship of the Rorschach schizophrenia index to psychotic features in a child psychiatric sample, J PERS ASSE, 76(2), 2001, pp. 209-228
In this study we investigated the reliability and validity of the Rorschach
Schizophrenia Index (SCZI) from Exner's (1978, 1993) Comprehensive System
for a sample of 413 child psychiatric inpatients by examining relationships
with the Personality Inventory for Children-Revised (PIC-R) and chart diag
noses. Interscorer reliability and internal consistency were acceptable. Mu
ltivariate analyses of variance results revealed significantly different PI
C-R profiles for those with and without elevated SCZI scores, with signific
ant differences emerging on the PIC-R Psychosis (PSY) scale and 2 cognitive
triad scales (Intellectual Screening and Development), which have been rep
orted to be more frequently elevated in PIC-R profiles of children with psy
chotic disorders. Significant differences were found across SCZI groups for
the PSY scale, Reality Distortion scale, reality testing critical items an
d chart diagnoses of psychotic disorder. Implications for clinical interpre
tation of the SCZI with children and issues for further research with this
population are discussed.
