No scales exist to measure appraisals of dissociative experiences. Dissociation is common in psychosis. Misinterpretations of dissociative experiences may maintain psychotic symptoms. Therefore, assessing appraisals in this context may be valuable.<\/jats:p><\/jats:sec><jats:sec id=\"S1352465820000958_as2\"><jats:title>Aims:<\/jats:title><jats:p>The primary aim was to develop a measure of key appraisals of dissociation in psychosis. Secondary aims were to test the relationship between appraisals and psychotic experiences (paranoia and hallucinations), and determine whether appraisals explain additional variance in psychotic symptoms above dissociative symptoms.<\/jats:p><\/jats:sec><jats:sec id=\"S1352465820000958_as3\"><jats:title>Method:<\/jats:title><jats:p>Fifty items were generated from transcripts of interviews with patients. The measure was developed and psychometrically validated via factor analysis of data from 9902 general population participants and 1026 patients with psychosis. Convergent validity, test\u2013re-test reliability, and internal reliability were assessed. Regression analyses tested relationships with psychotic symptoms.<\/jats:p><\/jats:sec><jats:sec id=\"S1352465820000958_as4\"><jats:title>Results:<\/jats:title><jats:p>A 13-item single-factor measure was developed. Factor analysis indicated good model fit [\u03c7<jats:sup>2<\/jats:sup>(65) = 247.173, comparative fit index (CFI) = 0.960, root mean square error of approximation (RMSEA) = 0.052]. The scale had good convergent validity with a rumination (non-clinical: <jats:italic>r<\/jats:italic> = 0.71; clinical: <jats:italic>r<\/jats:italic> = 0.73) and dissociation measure (<jats:italic>r<\/jats:italic> = 0.81; <jats:italic>r<\/jats:italic> = 0.80), high internal consistency (\u03b1 = 0.93; \u03b1 = 0.93), and excellent 1-week test\u2013re-test reliability [intraclass correlation (ICC) = 0.90]. It explained variance in psychotic symptoms (paranoia: 36.4%; hallucinations: 35.0%), including additional variance compared with dissociation alone (paranoia: 5.3%; hallucinations: 2.3%).<\/jats:p><\/jats:sec><jats:sec id=\"S1352465820000958_as5\"><jats:title>Conclusions:<\/jats:title><jats:p>The Cognitive Appraisals of Dissociation in Psychosis (CAD-P) measure is a psychometrically robust scale identifying appraisals of dissociative experiences in psychosis and is associated with the presence of psychotic experiences.
