The use of a sociobiological questionnaire (SQ) for the assessment of sexual dimorphism.

A sociobiology questionnaire (SQ) (Thiessen and Kittrell, 1980) was administered to 527 undergraduate males and females. Twenty-seven predictions were tested. Sixteen of the predictions were statistically confirmed, and eight were in the expected direction. Overall, females appeared to be more interested in their mate's success than their own and were more selective in the choice of mates. Males gave more evidence of competitiveness and tended to mate polygamously. The results are compatible with theoretical expectations about mating strategies (Buss, 1987; Rushton et al., 1984; Thiessen and Gregg, 1980). A number of problems with regard to the application of sociobiological and sociocultural theories to human behavior are discussed.
