Rm. Costello, PSYCHOMETRIC DEFINITION OF RORSCHACH DETERMINANT COMPONENT STRUCTURE, European journal of psychological assessment, 14(2), 1998, pp. 116-123
This is an empirical examination of Experienced Stimulation (es) and E
xperience Actual (EA) From Exner's Comprehensive System (CS) For Rorsc
hach's Test, spurred by Kleiger's theoretical critique. Principal comp
onents analysis, Cronbach's alpha, and inter-item correlational analys
es were used to test whether 13 determinants used to code Rorschach re
sponses (M, FM, m, CF+C, YF+Y, C'F+C', TF+T, VF+V, FC, FC', FV, FY, FT
) are best represented as a one, two, or more-dimensional construct. T
he 13 determinants appear to reflect three dimensions, a ''lower order
'' sensori-motor dimension (m + CF+C + YF+Y + C'F+C' + TF+T + VF+V) wi
th a suggested label of Modified Experienced Stimulation (MES), a ''hi
gher order'' sensori-motor dimension (FM + FV + FY + FT) with a sugges
ted label of Modified Experience Potential (MEP), and a third sensori-
motor dimension (M+FC+FC') for which the label of Modified Experience
Actual (MEA) is suggested. These findings are consistent with Kleiger'
s arguments and could lead to a refinement of CS constructs by aggrega
ting determinants along lines more theoretically congruous and more in
ternally consistent. A RA-MONA model with parameters specified was pre
sented For replication attempts which use confirmatory factor analytic
techniques.
