Purpose: The purpose of this study was to identify the occupational performance deficits experienced by cancer survivors in order to help develop a screening tool that would indicate a need for occupational therapy services in cancer survivorship care (before, during, and after being diagnosed with cancer). Methods: The delphi technique was used to develop a screening tool aimed to determine the need for occupational therapy services among cancer survivors. Multiple rounds were used to obtain feedback from content experts to continuously refine the screening tool (Keeney, Hasson, & McKenna, 2011). Researchers gathered ideas from survivors about their occupational performance deficits as well as information from current literature to inform and build and enhance screening tool items. Results: The most prominent occupational performance deficits indicated in the screening tool included rest and sleep, sexuality and intimacy, health and wellness, and performing job duties. Discussion: The current study validated occupational performance limitations found in current oncology literature, providing further insight into the relevance of these limitations in a group of cancer survivor content experts in order to inform the SOCS-OTS. Conclusion: Researchers of this study developed items for the SOCS-OTS based on issues faced by survivors validated by experts’ personal experiences as well as supporting literature. This study drew on the experiences of content experts with cancer to determine occupational performance deficits that could deem occupational therapy services necessary for cancer survivors. Further development of the SOCS-OTS is necessary to create an occupation-focused screening tool.
