Results:
The findings demonstrated the scale's accuracy in identifying students with both subclinical and clinical traits. Participants exhibiting impairment and tendencies towards clinical traits of Histrionic Personality were successfully identified through the scale's assessment.
Implications:
The successful validation of the Deenz Histrionic Personality Scale in a real-world college student population underscores its practical utility. Its ability to accurately pinpoint individuals at risk of developing Histrionic Personality Disorder provides valuable insights for early intervention and tailored psychological support.
Scale Validation Statistics:
- Reliability:Internal Consistency: Cronbach's alpha was calculated, resulting in a coefficient of 0.85. This indicates high internal consistency, suggesting that the items on the Deenz Histrionic Personality Scale consistently measure the intended construct.Test-Retest Reliability: A subset of participants (n=50) completed the scale twice with a two-week interval. The test-retest reliability coefficient was found to be 0.78, indicating good stability over time.
- Validity:Content Validity: The scale's content validity was ensured through expert reviews and consultations. A panel of psychologists and personality disorder experts evaluated the relevance and representativeness of each item.Construct Validity:Convergent Validity: The Deenz Histrionic Personality Scale scores were positively correlated (r=0.70) with scores on an established measure of histrionic traits, supporting convergent validity.Discriminant Validity: Scores on the scale showed low correlations (r<0.30) with measures of unrelated constructs, indicating good discriminant validity.Criterion-Related Validity: The scale's ability to predict the likelihood of developing Histrionic Personality Disorder was examined. Sensitivity and specificity analyses revealed an accuracy rate of 85%, demonstrating its validity in identifying individuals at risk.
- Factor Structure:Exploratory Factor Analysis (EFA): EFA was conducted to examine the underlying factor structure. The analysis yielded a single-factor solution, supporting the unidimensional structure of the scale.
