The Černis Felt Sense of Anomaly (ČEFSA) Scale: Psychometric Properties and Validity of a German Version

Past research on dissociation has predominantly relied on broad questionnaires, presenting ambiguous and overlapping themes in describing dissociative experiences. A new measure, the Černis Felt Sense of Anomaly (ČEFSA) scale (Černis et al., 2021), assesses a subgroup of dissociative experiences where felt sense of anomaly is inherent. In this article, we present a German translation of the 35-item ČEFSA scale. In Study 1 (N = 130), we investigated the factor structure of the initial translation. We describe how necessary revisions were implemented. In Study 2 (N = 243), we show that the seven ČEFSA subscales had an appropriate factor structure and sufficient reliability. In terms of validity, the convergent, discriminant, and criterion correlations were mostly as expected. Some subscales showed high intercorrelations, making it difficult to distinguish them. We conclude that the German version of the ČEFSA scale provides a reliable and valid tool for the detailed assessment of dissociation.
