The DUCP measures the consumption-specific desire to own things few others have — distinct from Tian et al.'s (2001) CNFU (id:447) in its focus on acquisition and possession goals rather than identity expression through counterconformity. Validated with student and adult samples (alpha=0.78 for both), test-retest r=0.85 over 2 weeks, and behavioural criterion validity (artistic theatre patrons M higher than second-run theatre patrons). Correlates with status aspiration, need for uniqueness, acquisitiveness, power-prestige, competitiveness, informational influence, normative influence, and possessiveness. No gender differences; modest negative correlation with age (younger consumers score higher). Mean scores 24.8–26.2 across samples.
