Willingness toward psychosocial support during cancer treatment: a critical yet challenging construct in psychosocial care.

Psychosocial distress screening, mandated by the American College Surgeons' Commission on Cancer, continues to be implemented across cancer centers nationwide. Although measuring distress is critical to identifying patients who may benefit from additional support, several studies suggest that distress screening may not actually increase patients' utilization of psychosocial services. While various investigators have identified barriers that may impede effective implementation of distress screening, we posit that patients' intrinsic motivation, which we term patients' willingness, may be the biggest predictor for whether cancer patients choose to engage with psychosocial services. In this commentary, we define patient willingness towards psychosocial services as a novel construct, distinct from the intention toward a certain behavior described across pre-existing models of health behavior change. Further, we offer a critical perspective of models of intervention design that focus on acceptability and feasibility as preliminary outcomes thought to encompass the willingness construct described herein. Finally, we summarize several health service models that successfully integrate psychosocial services alongside routine oncology care. Overall, we present an innovative model that acknowledges barriers and facilitators and underscores the critical role of willingness in health behavior change. Consideration of patients' willingness toward psychosocial care will move the field of psychosocial oncology forward in clinical practice, policy initiatives, and study design.
