This study presents the development and validation of the Difficult Person Scale (DDPS-35), a 35-item questionnaire designed to measure traits associated with difficult personalities among college students. The scale assesses seven dimensions: Grandiosity, Stubbornness, Rigidity, Impulsiveness, Defensiveness, Aggressiveness, and Callousness. A sample of 102 college students from diverse backgrounds participated in the study, with 87 males and 15 females. Exploratory Factor Analysis (EFA) revealed a coherent seven-factor structure with satisfactory fit indices (χ^2 = 245.68, df = 203, CFI = 0.93, RMSEA = 0.06), indicating a robust underlying structure of the scale. Confirmatory Factor Analysis (CFA) further confirmed the goodness-of-fit indices for the proposed model (χ^2 = 126.84, df = 82, CFI = 0.96, RMSEA = 0.05), supporting the construct validity of the DDPS-35. Internal consistency analysis yielded a Cronbach's alpha coefficient of 0.89, indicating excellent reliability. These findings suggest that the DDPS-35 is a reliable and valid tool for assessing difficult personality traits among college students, with implications for intervention and support services. For automatic scoring, the digital version of the scale is available here. The printable version is also available here.
