Purpose: To compare the Cancer Distress Scales for Adolescents and Young Adults (CDS-AYA)—Emotional and Impact scales—with the Edmonton Symptom Assessment Scale–revised (ESAS-r), Hospital Anxiety a...

Purpose: The use of valid and reliable screening tools to measure distress may help to identify adolescent and young adults (AYA) with cancer who need additional support. Our study describes a two-phase approach to adapt the Australian AYA oncology and survivorship distress screening tools for use in Canada. Methods: Phase 1 involved refining the Australian AYA oncology and survivorship screening tools using cognitive interviews with AYA with cancer and feedback from experts. In phase 2, a field-test study was performed, and Rasch Measurement Theory (RMT) analysis was used for item reduction and to examine reliability and validity. Results: Cognitive interviews with 45 AYA with cancer and feedback from 25 experts resulted in a field-test version of the Cancer Distress Scales for AYA (CDS-AYA) consisting of 91 items that measure 9 constructs. The field-test sample included 515 participants. RMT analysis identified five scales (impact of cancer, physical, emotional, cancer worry, and cognitive) with ordered thresholds, good item fit (-3.70 to 2.82), and acceptable reliability (0.85-0.94). Reliability for the remaining four scales (employment, education, practical, and social) was low, and the scales were retained as checklists, with the exception of the social scale that was dropped. Conclusion: The final item-reduced CDS-AYA consist of 48 items in 5 scales, with 2 stand-alone items in the physical and emotional scales and 23 items in 3 checklists. The CDS-AYA can be used in research and in clinical practice to measure distress in AYA with cancer.

Purpose: Distress is an important issue facing adolescent and young adults (AYA) with cancer due to their stage of development. Metrics are necessary to help improve psychosocial outcomes in this population. This study determined cut-points for the newly developed Cancer Distress Scales (CDS)-AYA. Methods: The CDS-AYA is a new patient-reported outcomes measure that comprises five independently functioning scales, including the following: Impact of Cancer (12 items), Physical (12 items), Emotional (11 items), Cognitive (8 items), and Cancer Worry (5 items). Canadian AYA with cancer 15-39 years of age completed the CDS-AYA and the Hospital Anxiety and Depression Scale (HADS), as part of the CDS-AYA field test. Only patients who had completed responses to the CDS-AYA and HADS were included in these analyses. Receiver operating characteristic (ROC) curve analysis was used to generate cut-points for five CDS-AYA scales based on distress defined by the HADS anxiety and HADS depression scale. Results: In total 453 of 515 respondents had complete data for the CDS-AYA and HADS were included in analyses. Area under the curve (AUC) in the ROC analyses ranged from 0.75 to 0.85. The CDS-AYA Emotional scale had the greatest AUC. The cutoff value for the Emotional scale was 27 based on the HADS anxiety scores (78.3% and 78.9%). Conclusions: The five CDS-AYA scales had fair to good accuracy when classifying the none/low and moderate/severe distress categories based on HADS anxiety and depression scales. For screening purposes, it is recommended that the Emotional scale or Impact of Cancer scale be utilized.
