This study seeks to address the disagreement in the literature about compulsive buying behavior's (CBB) dimensional structure and tests for cross‐cultural and cross‐gender invariance in young British, Chinese, Czech and Spanish consumers using structural equation modelling. The results show that CBB has two compulsive dimensions: Compulsive Purchasing (CP), and Self‐control Impaired Spending (SIS). These dimensions are cross‐culturally invariant, although the influence of SIS on CBB is higher in more developed countries, particularly among females. The confirmation of the SIS dimension and the external validity of the CBB construct established through the cross‐cultural invariance in CBB dimensions indicate that screening tools should be revised accordingly. The SIS dimension has possibly been previously misinterpreted as impulsive and/or as spontaneous buying and may explain the higher incidence of CBB among female consumers.
