A short screening instrument for mental health problems: The Symptom Checklist-27 (SCL-27) in Poland and Germany

Objective. The symptom checklist SCL-27 is a short, multidimensional screening instrument for mental health problems. It contains six scales: depressive, dysthymic, vegetative, agoraphobic and sociophobic symptoms; symptoms of mistrust; and a global severity index (GSI-27). Methods. A survey of two student samples from Poland and Germany (n similar to 400) is presented. Results. Most scales of the SCL-27 showed good to satisfactory reliability (i.e. Cronbach's alpha > 0.70). Some items displayed different characteristics in students than in non-student samples. These discrepancies can be explained partly by the particular situation students face and partly by some country-specific or language-specific aspects of the measuring instrument. Differences between Polish and German students were marginal at best; in general, the Polish students tended to assent more easily to the items of the SCL-27 than did the German students. Conclusions. The SCL-27 is suitable for international comparisons. In both, Germany and Poland, students display a characteristic response pattern that differs from those of other samples. It can be applied as a separate instrument or for reanalysis of data collected with the SCL-90_R.
