Abstract :
This study presents a new questionnaire to assess schema modes: the Schema
Mode Inventory (SMI). Method: First, the construction of the short SMI (118 items) was
described. Second, the psychometric properties of this short SMI were assessed. More
specifically, its factor structure, internal reliability, inter-correlations between the subscales,
test-retest reliability and monotonically increase of the modes were tested. This was done in
a sample of N = 863 non-patients, Axis I and Axis II patients. Results: Results indicated
a 14-factor structure of the short SMI, acceptable internal consistencies of the 14 subscales
(Cronbach α’s from .79 to .96), adequate test-retest reliability and moderate construct validity.
Certain modes were predicted by a combination of the severity of Axis I and II disorders, while
other modes were mainly predicted by Axis II pathology. Conclusions: The psychometric
results indicate that the short SMI is a valuable measure that can be of use for mode assessment
in SFT.
