title: [Assessment of AIDS risks: effects of different scale ranges and preventive knowledge].
abstract: In a sample of 552 respondents effects of different scale ranges and respondents' knowledge about AIDS for answering questions about AIDS-risks were examined. Knowledge was assessed with 12 items related to risks for HIV infections and preventive measures. AIDS hazards for different groups (prostitutes, fixers, hospital personnel, homosexuals, and haemophiliacs) had to be rated with five items, one for each group. Response variations were assessed in three parallel questionnaire versions with different ranges of risk assignments. Estimations had to be performed in comparison with the average population. Some groups were consistently rated to be at high risk, others were assigned low risks for becoming infected with the HIV-virus. The analysis of response patterns revealed that the three versions of numeric quantifiers determined the risk ratings only to some extent. The distribution patterns suggest that our subjects had an ordinal risk ordering in mind that might better be expressed in verbal terms. The knowledge about AIDS had no systematic effects on response behavior.
