Abstract

Rumination has been identified as a negative psychological response of women diagnosed with breast cancer. The aim of the present study was to validate the Event-Related Rumination Inventory (ERRI) in Greek women with breast cancer. Sixty female patients with newly diagnosed breast cancer were included in the study. The ERRI questionnaire was translated with the back-forward procedure. Sociodemographic, anthropometric, and medical parameters were also assessed. The principal component analysis resulted in the following two-factor solution: (1) intrusive thoughts and (2) positive outcome. All subscales showed satisfactory internal consistency and variance, relative to theoretical score ranges. Subscale scores and the total score were significantly correlated with post-traumatic growth, distress, depression, and anxiety, demonstrating good criterion validity. Associations with patients' sociodemographic and medical characteristics, such as the stage of the disease and the type of treatment, were also identified. The Greek version of the ERRI provides valid and reliable measures of rumination when administered to women with breast cancer.
