Abstract
Objective: The Worries About Recurrence or Progression Scale (WARPS) was recently validated in four common chronic illnesses other than cancer, after a rigorous development process based on the COSMIN criteria. Available measures of fear of progression or fear of cancer recurrence (FCR) have been criticised for not meeting all COSMIN criteria. Therefore, this study aimed to explore the psychometric properties of the WARPS in a cancer sample to assess its applicability to measure FCR.
Methods: We recruited 346 participants living with or beyond cancer for an online survey. The psychometric properties of the WARPS were examined using a confirmatory factor analysis. Convergent validity was assessed against the current gold standard questionnaires and constructs related to FCR. Some participants completed a follow-up survey 2 weeks later, to assess the test-retest reliability. Finally, a Receiver Operating Characteristics analysis was conducted to determine clinical cut-offs for the WARPS.
Results: Confirmatory factor analysis confirmed that the WARPS has one underlying factor, fear of recurrence or progression (FRP), with adequate model fit. The WARPS demonstrated excellent internal consistency, test-retest reliability and showed convergent validity. ROC analysis revealed a cut-off of 54 for moderate, and 65 for severe FCR on the WARPS.
Conclusions: The WARPS demonstrated good psychometric properties in a cancer sample. It has the capacity to be used as a screening tool to identify clinical levels of FCR. The WARPS was developed consistent with the COSMIN criteria and overcomes some of the limitations of existing measures.
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.
