This study investigated the relationship between the Child Behavior Checklist/4-18 (CBCL/4-18) and two modified measures of social desirability, the Marlowe-Crowne Social Desirability Scale and the Edwards Social Desirability Scale with a sample of 65 parents of normal children from grades K-7. Results from correlational and multiple regression analyses showed that the Aggressive Behaviors and Attention Problems cross-informant syndromes were modestly associated with social desirability scale scores. The relevance of findings are discussed in terms of the susceptibility of behavior rating scales to the self-deception and other-deception factors of social desirability [Paulhus, D. L. (1984).
