Reliability, Validity, and Psychometric Properties of the Greek Translation of the Cambridge Depersonalization Scale (CDS)
Dados Bibliográficos
INTRODUCTION: The Cambridge Depersonalisation Scale is meant to capture the frequency and duration of depersonalisation symptoms over the 'last 6 months'. METHODS: In order to develop a Greek version of CDS scale, the CDS scale was translated in Greek by 2 psychiatrists. Then, the Greek version of CDS scale was back-translated by a person who did not knew the original English version. The back-translated version was reviewed in order to establish whether is consistent with the original English version. After this procedure we administered the Greek version of CDS scale to a sample of 294 Greeks in order to assess the reliability and the validity of the Greek version of scale. RESULTS: The five components solution accounted for 58.204% of the total variation. Initial eigenvalues of the five components were: factor 1=11.555, factor 2=1.564, factor 3=1.356, factor 4=1.247 and factor 5=1.157. Six items did not load on any factor. Correlations between factors were low ranged from 0.134 to 0.314 and no complex variables were found. Cronbach's alpha and Guttman split-half coefficient were used to evaluate interval consistency of CDS scale in 294 individuals. The alpha coefficients and Guttman split-half coefficient of the CDS scale were 0.938 and 0.921, respectively. The test-retest reliability proved to be satisfactory. The intraclass correlation coefficients for the total CDS score was very good and equal to 0,883. The CDS scale correlated highly with the SCL-90 and all subscales (p-value<0.0001). CONCLUSION: The psychometric strength of CDS - Greek its reliable for its future use, particularly for screening for subjects with possible diagnosis of CDS
