Abstract: The paper presents the construction and studies of reliability and construct validity of a new questionnaire, the Problematic Shopping Scale, designed to evaluate the shopping behaviour. In Italy, in fact, there is not a valid questionnaire to evaluate the shopping behaviour. The questionnaire, in its final form, is composed of 22 item and shows good internal consistency. PSS can be considered a reliable psychometric tool suitable to assess problematic buying behaviour. Also, it is an instrument easy to administer and to score. Further research is needed to analyse concurrent validity by means of clinical criteria, and to obtain a standardization of the scale in Italian representative sample.
