Development of the lying in everyday situations scale / Christian L. Hart, Jelisa M. Jones, John A. Terrizzi, Jr., Drew A. Curtis

Deception researchers have developed various scales that measure the use of lying in specific contexts, but there are limited tools that measure the use of lies more broadly across the various contexts of day-to-day life. We developed a questionnaire that assesses the use of various forms of lying, including protecting others, image enhancement, saving face, avoiding punishment. vindictiveness, privacy, entertainment, avoiding confrontation, instrumental gain, and maintaining and facilitating relationships. The results of a factor analysis brought our original 45-item scale down to a two-dimensional, 14-item scale that we have titled the Lying in Everyday Situations (LiES) scale. In three studies, the concurrent validity of the scale was assessed with several domain-specific lying scales, two Machiavellianism scales, a social desirability scale, and reports of actual lie frequency over a 24-hour period. The scale was also assessed for interitem consistency (Cronbach's a) and test-retest reliability. We found that the LiES scale was a reliable and valid measure of lying. The LiES scale may be a useful tool for assessing the general tendency to lie across various contexts.
