The Sensory Gating Inventory (SGI) is an instrument investigating daily
experiences of sensory gating deficit developed for English speaking
schizophrenia patients. The purpose of this study is to design and validate a
French version of the SGI. A forward-backward translation of the SGI was
performed. The psychometric properties of the French SGI version were analyzed. A
confirmatory factor analysis (CFA) was carried out to determine whether factor
structure of the French version is similar to the original English version. In a
sample of 363 healthy subjects (mean age=31.8 years, S.D.=12.2 years) the
validation process revealed satisfactory psychometric properties: the internal
consistency reliability was confirmed for each dimension; each item achieved the
0.40 standard threshold for item-internal consistency; each item was more highly
correlated with its contributive dimension than with the other dimensions; and
based on a CFA, we found a 4-factor structure for the French version of the SGI
similar to the original instrument. Test-retest reliability was not determined.
The French version of the SGI is a psychometrically sound self-report for
measuring phenomenological sensory gating experiences.
