Confirmatory factor analysis of the Purchaser Style Inventory for Sport Products (PSISP)

• To date, none of the consumer shopping behavior measuring instruments has been validated.
• This is the first study in the field to cross validate a purchaser style inventory, the PSISP.
• Confirmatory factor analysis shows that the model provides good fit to the data.
• We confirm that the revised PSISP (PSISP-II) is a reliable inventory for measuring consumer decision styles in purchasing sport products.

Consumers are bombarded every day by numerous promotion messages, and their decision making in purchasing sport goods or services is frequently confused by these advertised information (Lysonski, Durvasula, & Zotos, 1996). For this reason, research in consumer decision-making styles has become increasingly popular. In 2009, Bae, Lam, and Jackson developed the Purchaser Style Inventory for Sport Products (PSISP) to identify consumers’ shopping behaviors. However, the PSISP was exploratory in nature. The purpose of this study was to validate the PSISP using confirmatory factor analysis. Participants (N = 455) were college students in the southern region of the United States. Fit indices (e.g., CFI = .92, SRMR = .068, RMSEA = .065: 90% CI = .062; .068) indicated the model provided reasonable fit to the data. After model respecification, the 37-item PSISP-II model significantly (p < .001) improved and included nine latent factors: Quality, Brand, Fashion, Recreation, Price, Impulse, Confusion, Habit, and Endorsement. It was concluded that the PSISP-II was a reliable scale in measuring consumer decision-making styles in purchasing sport products.
