Lie Scale (L Scale) of the MMPI

The Lie Scale, or 'L' Scale, is a specific validity scale within the MMPI designed to detect if a respondent is 'faking good.' This occurs when an individual underreports psychological problems to appear healthier than they are. The scale consists of 15 items, and a tendency to 'fake good' may be indicated if the person agrees with numerous unrealistically positive statements, such as 'I have never told a lie.'
