@entity1 @entity6004
Epidemiological studies related to the occurrence of @entity6004 commonly use symptom check-lists. The results of such studies depend on, amongst others, the construction of the questionnaire and especially on the specification of the value of the questionnaire (GSI) which is determined as the boundary between the "psychophysiological" or organic symptoms and @entity6004 . A control study was carried out on the norms of two symptom checklists which have been used for many years in Poland: SCL-"S" (73 symptoms), most often diagnosed in @entity6004 @entity1 , at the time of constructing the questionnaire and the SCL-"O" (the same 73 + 62 other symptoms). The criterion population was made up of 843 untreated subjects and 2026 @entity1 of day-hospitals. The norms specified by the method of finding the "optimal cut-off point" were approx. 5% in the SCL-"S" and 3% in the SCL-"O" higher for the cohort of @entity1 than for @entity1 . According to those norms, about 30% of the untreated population gains the same result of Global Severity Index (GSI) as about 90% of @entity1 treated for @entity6004 and could be diagnosed as @entity6004 . The GSI norms for the SCL-"S" more often indicated the existence of these disorders in the group of untreated @entity1 than in the @entity1 's group, while the norms of SCL-"O" indicate a similar frequency of the disease independently of the gender. The symptom frequency analysis presenting differences in the @entity1 (1165 ss.) and @entity1 (861 ss.) @entity1 groups and lead also to the hypothesis on the dependency of such epidemiological data on the construction of the symptom check-lists--especially the number of variables concerning symptoms more frequent in the female and/or in the male populations.
