Recent efforts to operationalize persons' readiness to adopt a self‐management approach to chronic pain have met with promising, but somewhat limited, results. The current study describes the development and psychometric evaluation of a German version of Pain Stages of Change Questionnaire (PSOCQ). A new item pool was developed to attempt to improve in particular the discriminant validity of the scales and in order to obtain a shortened measure. The items were administered to 494 chronic pain patients who were split into two independent samples. Item‐ and factor‐analysis performed on data from one half of the sample resulted in four scales: precontemplation, preparation, action, and maintenance. The scales of the new measure, called the “Freiburg Questionnaire‐Stages of Chronic Pain Management (FQ‐STAPM)”, showed good indices of reliability, homogeneity, and discriminant validity. Both the concurrent and divergent validity indices and the relationships between scale scores and pain related variables proved to be consistent with the transtheoretical model. Confirmatory factor analysis using LISREL performed on the second half of the sample supported the goodness‐of‐fit of the structure model. Implications of these findings for future research exploring the relevance of the pain stages of change model are discussed.
