Abstract

The responses of a predominantly British sample of 479 persons undergoing psychiatric treatment (as in-, out and day patients), and two British samples from the general population, on the Personal Disturbance Scale (DSSI/sAD), were separately subjected to Mokken scale analyses. In all three instances, moderately strong, reliable and statistically significant Mokken scales were produced from the 14 item pool. These scales showed strong similarity in having seven items in common from their respective 10, 10 and 9 item Mokken scale solutions. These results, establishing a hierarchical item ordering, offer further validation for the DSSI/sAD.
