The Development of the Brooding Scale [PDF]
Psychiatry Investigation, 2019 The purpose of this study was to develop a Brooding Scale (BS) and to confirm its psychometric properties.A preliminary questionnaire was developed based on a literature review and face-to-face interviews with healthy subjects. To evaluate reliability and construct validity, a 15-item BS was administered to 124 healthy subjects. Convergent validity was
