Drawing on the theoretical foundation of obsessive-compulsive spectrum disorder, this article develops an expanded conceptualization and new measure of consumers' proclivity to buy compulsively. Compulsive buying is defined as a consumer's tendency to be preoccupied with buying that is revealed through repetitive buying and a lack of impulse control over buying. This measure includes dimensions of both obsessive-compulsive and impulse-control disorders. By measuring income-dependent items or consequences of compulsive buying separately from the compulsive-buying scale, we develop a measure that has a strong theoretical foundation, well-documented psychometric properties, and an ability to be applied to general consumer populations.

Seven price-related constructs—five consistent with a perception of price in its “negative role” and two consistent with a perception of price in its “positive role”— are used as independent variables to predict marketplace responses/behaviors in five domains: price search, generic product purchases, price recall, sale responsiveness, and coupon redemption. The price-related constructs explain a significant amount of variance in all five domains, providing evidence of predictive validity. Results of a higher order factor analysis are also reported, which provide some support for the positive-negative perception of price taxonomy.
