Social desirability and self-reported weight and height.

The present study examines the relationship between the desire to conform to perceived societal norms and the misreporting of weight and height. Self-reported and measured weights and heights for 56 young, healthy non-obese volunteers were assessed and compared to scores on the Marlowe Crowne Social Desirability Scale (MCSDS). Discrepancies between actual and self-reported weights for females were directly related to actual weight (r = 0.66, P<0.0001). The same was not true for males (r = 0.03). Height was significantly overreported, regardless of gender (P<0.004). Most importantly, for females, MCSDS scores were significantly correlated with the discrepancy between actual and self-reported weights after statistically adjusting for differences in actual weight (r = 0.51, P<0.0001). Results suggest that the misreporting of weight among young, non-obese women may be directly influenced by the desire to conform to perceived societal norms.
