Eppendorf Schizophrenia Inventory (esi):
presentazione della versione italiana
The Italian version of the Eppendorf Schizophrenia Inventory
Objective
Preliminary validation data are presented
for the Italian version of the Eppendorf Schizophrenia Inventory (ESI: Mass,
2000), a self-administered 40-item questionnaire exploring psychosis-related
subjective experiences, grouped in five subscales. Four pertain to attention
and speech impairment (AS), auditory uncertainty (AU), ideas of reference
(IR), and deviant perceptual phenomena (DP). A further subscale controls for
frankness (FR) in completing the inventory.
Method
The Italian version of the ESI was obtained through translation, back-translation
and resolution of discrepancies by discussion and consensus with the author
of the original. The Italian version of the ESI has been administered to 50
inpatients with Schizophrenia according to ICD-10 criteria and to 50 controls
matched for sex, age, and educational level. Patients were also assessed using
the Positive and Negative Symptoms Scale (PANSS) and completed another inventory
of subjective experiences, the Frankfurter Complaint Questionnaire (FCQ).
Results
The total and the four subjective experiences subscales’ scores of the
Italian ESI were significantly higher in patients, while there were no differences
in the FR scores. In patients, significant correlations were found between
ESI total and subscale scores with duration of illness and negative symptoms
PANSS scores. Significant positive correlations were also found between ESI
total and subscale scores and FCQ global and subscale scores. Cronbach’s alphas
for the Italian ESI and its subscales ranged from .65 to .89.
Discussion
The Italian version of the ESI appears to have satisfactory concurrent
validity and acceptable internal consistency; preliminary data showing discriminant
validity between patients with Schizophrenia and controls support further
study of its test-retest reliability and discriminant validity qualities between
patients with Schizophrenia and other diagnostic groups. In the clinical setting,
the ESI may represent a useful tool for the evaluation of subjective experiences.
