Full context:   Lexical measures use individual adjectives that reflect extravert and introvert traits, such as outgoing, talkative, reserved and quiet. Words representing introversion are reverse-coded to create composite measures of extraversion-introversion running on a continuum. Goldberg (1992) developed a 20-word measure as part of his 100-word Big Five markers. Saucier (1994) developed a briefer 8-word measure as part of his 40-word mini-markers. However, the psychometric properties of Saucier's original mini-markers have been found to be suboptimal with samples outside of North America. As a result, a systematically revised measure was developed to have better psychometric properties, the International English Mini-Markers. The International English Mini-Markers has good internal consistency reliabilities, and other validity, for assessing extraversion-introversion and other five-factor personality dimensions, both within and, especially, without American populations. Internal consistency reliability of the extraversion measure for native English-speakers is reported as a Cronbach's alpha (α) of 0.92, that for non-native English-speakers is α of 0.85.
