[Validity of the ICD-10 Symptom Rating (ISR) in a Non-Clinical Sample]. / Faktorielle Validität und Konstruktvalidität des ICD-10-Symptom-Ratings (ISR) in einer klinisch weitgehend unauffälligen Stichprobe.

Introduction The ICD-10 symptom rating (ISR) is a self-rating instrument that is based on ICD-10 syndromes. Can previous findings concerning its validity be replicated in a non-clinical sample? Material & Methods N=428 study participants - mainly students - completed the ISR and the SCL-90-R in an online survey. Results The assumed factorial structure was replicated with a good model fit. The correlations between the content-related scales of the two instruments ranged from rmin=0.60 to rmax=0.85. Study participants indicated that they did not find completing the ISR stressful. Discussion and Conclusions These results indicate good validity and applicability of the ISR.
