Relative Susceptibility of Catch-Phrase and Propositional Scales to Social Desirability
To investigate the relative susceptibility of catch-phrase versus propositional (traditional) scales the Crowne-Marlowe (C-M) scale of social desirability, as well as the Wilson-Patterson (W-P) catch-phrase conservatism scale and a specially constructed propositional conservatism scale covering the same content area, were given to 90 South African high-school pupils under anonymous conditions and instructions to fake a ‘conservative’ or ‘liberal’ impression. A similar group of 40 Ss rated the various items in the two scales in terms of their social desirability. Finally, a similar group of 80 Ss completed the two scales under ‘real life’ conditions that have been shown to ‘demand’ liberal and conservative replies respectively. Since (a) the correlation with the C-M social desirability scale was significantly lower for the W-P scale, (b) the difference between Ss' scores under anonymous and faking conditions was significantly smaller for the W-P scale, and (c) the mean scores of the two unlike ‘real life’ conditions for the groups given the W-P scale differed more than those given the other scale, it was concluded that, as regards these scales, the catch-phrase type of questionnaire shows less susceptibility to social desirability.
