ABSTRACT
The SDS consists of 12 items selected initially by requesting a large sample of “normal” adults to record their recurrent fantasies. An additional sample of respondents reviewed these fantasies and checked off those they had experienced by indicating the degree of frequency on a Likert-type scale. Those items bearing specifically on sexuality and showing reasonable intercorrelations as well as relatively normal distributions on the 5-point scale were employed for further refinement in the procedure used for generating the 12-item scales of the IPI (Singer & Antrobus, 1963, 1972). In general, this scale has not been used to any degree independently of the other 27 scales that make up the IPI because it loads on at least two of the three second-order factors that consistently emerge from the larger questionnaire.
