PDI-G
Peters et al. Delusions Inventory - deutsche Fassung
Short abstract
The German adaptation of the PDI, PDI-G, as a short (k = 21 items) and long version (k = 40 items) measures subclinical delusions in adults on three dimensions (preoccupation, temporal preoccupation, strength of conviction). The Present State Examination (PSE; Wing et al., 1974) was used to construct the original. Reliability: The internal consistency according to Cronbach's alpha was α = .85 (normal population) and α =.89 (patients). Validity: There are correlations with the scales of the SPQ-G (r = .45 and r = .23).
