Preliminary validation of the Cognitive Affective Mindfulness Scale-Revised in cancer populations.
Objective: A brief, valid, and comprehensive measure of mindfulness is needed for cancer populations. This study examined the factor structure, internal consistency, construct validity, and measurement invariance of the 10-item Cognitive Affective Mindfulness Scale-Revised (CAMS-R) in patients with cancer.
Methods: Patients with breast, gastrointestinal, lung, or prostate cancer (N = 404, 50% stage IV cancer, 51% women) were recruited from academic and public clinics in Indianapolis, IN. Patients completed the CAMS-R and other psychological measures at one time point. Confirmatory factor analysis (CFA) was used to examine the dimensionality of the CAMS-R. Internal consistency and construct validity were also assessed. Measurement invariance was examined for gender, cancer type, and cancer stage.
Results: CFA showed that the original CAMS-R structure with four first-order factors (attention, present focus, awareness, and acceptance) and one second-order factor (mindfulness) had a reasonable fit (RMSEA = 0.09, CFI = 0.95, SRMR = 0.04). Internal consistency was excellent (α = 0.90). The CAMS-R total score showed significant positive associations with several subscales of a widely used mindfulness questionnaire and self-compassion (rs = 0.61-0.66) and significant negative associations with anxiety, depressive symptoms, rumination, psychological inflexibility, and avoidant coping (rs = -0.35-0.58). Measurement invariance testing indicated that the CAMS-R was invariant across populations of varying genders, cancer types, and stages.
Conclusions: Findings provide preliminary support for using the CAMS-R in cancer populations. Future research should assess the responsiveness of the CAMS-R to intervention.
期刊介绍:
Psycho-Oncology is concerned with the psychological, social, behavioral, and ethical aspects of cancer. This subspeciality addresses the two major psychological dimensions of cancer: the psychological responses of patients to cancer at all stages of the disease, and that of their families and caretakers; and the psychological, behavioral and social factors that may influence the disease process. Psycho-oncology is an area of multi-disciplinary interest and has boundaries with the major specialities in oncology: the clinical disciplines (surgery, medicine, pediatrics, radiotherapy), epidemiology, immunology, endocrinology, biology, pathology, bioethics, palliative care, rehabilitation medicine, clinical trials research and decision making, as well as psychiatry and psychology.
This international journal is published twelve times a year and will consider contributions to research of clinical and theoretical interest. Topics covered are wide-ranging and relate to the psychosocial aspects of cancer and AIDS-related tumors, including: epidemiology, quality of life, palliative and supportive care, psychiatry, psychology, sociology, social work, nursing and educational issues.
Special reviews are offered from time to time. There is a section reviewing recently published books. A society news section is available for the dissemination of information relating to meetings, conferences and other society-related topics. Summary proceedings of important national and international symposia falling within the aims of the journal are presented.
