Reliability assessment of the Polish version of the Groningen Social Disabilities Schedule II (GSDSII)             63

Summary

The paper describes a reliability study conducted on the Polish version of the Groningen Social Disabilities Schedule II (GSDSII). 127 inpatients hospitalized in the Department of Psychiatry of the Medical University of Wroclaw were included in the study. Each patient was assessed by two raters (interrater and retest reliability) who were assigned to the roles of interviewer and observer in a balanced, randomized way. Several statistical indices of reliability were calculated for the interviewer-observer and retest comparison. The interview showed an overall good reliability. The lowest values were found for those items where the reference group expectations were relationship-dependent.
