Development and Validation of the Trait-State Personality Questionnaire

Although plenty of research has been conducted on the Big Five Personality traits. The present study aimed to develop a scale that measured the Big Five as both a personality trait and state. Two studies were conducted (Study 1, N=597) to examine the internal consistency and structure of the Trait-State Personality Questionnaire and (Study 2=352) to examine the predictive validity by exploring the relationship between the big five and adaptability and satisfaction with life. Overall, the finding revealed good internal consistency α=.926, predictive validity, and measurement variance. Potential applications of the Trait-State Personality Questionnaire are discussed.
