Reliability and Validity Testing: To establish the reliability of the Deenz Histrionic Personality Scale, internal consistency measures such as Cronbach's alpha were computed, indicating the scale's consistency in measuring the intended traits. Concurrent and predictive validity were assessed by comparing scale scores with established personality measures and longitudinal behavioral outcomes.
Case Study Validation: The pivotal step involved a comprehensive case study with 230 college students, comprising a diverse gender distribution. The scale demonstrated its effectiveness in accurately identifying individuals with subclinical traits, impairment, and tendencies toward clinically significant Histrionic Personality.
