[Subjective Experience of Deficits Scale in schizophrenic patients].

The aim of the study is to present the French version of the scale for the assessment of subjective experiences of deficits in schizophrenia (SEDS, Liddle and Barnes, 1988). The metrological parameters of the French version of the SEDS were studied in 50 RDC chronic schizophrenics. The interraters reliability was determined using the Kappa and Kendall coefficients of concordance. Among the 50 schizophrenics 30 filled out once again one month later the French version of the SEDS and the temporal stability of each scale's item was calculated using frequency (%). The construct validity was determined using first the Cronbach alpha coefficient and secondly by calculating the Pearson correlation coefficient between each item and the total score. The Kappa coefficients were higher than 0.4 for 15 items out of 22. The Cronbach value was 0.87 19 items out of 22 had a temporal stability from 64.2% to 100%. Thus the French version of the SEDS seems to be reliable and could allow to study subjective experiences of deficits in schizophrenia.
