Development of Perceived Narcissistic Tendencies Scale among Secondary School Teachers

Abstract

The Perceived Narcissistic Tendencies Scale (PNTS) was developed in three phases: (1) item generation, (2) expert opinion and pilot testing, and (3) psychometric determinism. The study included 200 participants with diverse demographics, with a mean age of 31.31 (SD = 9.11) and an average of 8.44 years of job experience (SD = 8.42). An Exploratory Factor Analysis with varimax rotation on 38 items revealed three factors: Social Exploitation (α = .85), Haughtiness (α = .82), and Self-Preoccupation (α = .79), comprising 37 items in total. These factors explained 34.18% of the variance. Inter-factor correlations were significant, ranging from .35 to .43. The scale’s split-half reliability, assessed using the Odd-Even method, showed a correlation of .79 (p < .001), with internal consistencies of .76 and .81 for Forms A and B, respectively. The PNTS demonstrates strong validity and reliability, making it an effective tool for assessing narcissistic tendencies.
