Attitude-behaviour correlation, social desirability and perceived diagnostic value

The correlations between attitude scales and behavioural criteria were studied. A multiple act criterion was found to be more predictable than the average predictability of single criteria. The predictability of single criteria was related to the domain representatives of criteria and how much act performance correlated with rated social desirability of the act. Domain representativeness was uncorrelated with the correlation between act performance and social desirability. Perceived diagnostic properties of acts were also related to attitude-criterion correlations.
