[Development of the "ICD-10-Symptom-Rating"(ISR) questionnaire]

Construction of the newly developed "ICD-10 Symptom Rating" (ISR) is presented together with some statistical data. This questionnaire is founded on the well-known ICD-10, according to which symptoms are relevant for assessing psychological disorders. The ISR aims at a comprehensive evaluation of the severity of psychological disorders. The ISR 2.0 has 29 items and six syndrome scales: Depression, Anxiety, Obsessive/Compulsive, Somatoform, Eating Disorders, and the Supplementary Scale, which covers a variety of syndromes, as well as a total score.

In a first cross-validation with 108 patients, some rather high correlations were found between the SCL-90-R and the ISR. They ranged from r = 0.78 to 0.37 for the individual syndrome scales, and amounted to r = 0.78 for the GSI versus the total score.
