Treatment side effects and decreased quality of life associated with androgen deprivation therapy (ADT) suggest the need for supportive services for prostate cancer (PC) patients receiving ADT. Nonetheless, uptake of services is low, suggesting that PC patients' preferences are not being addressed. We examined interest in supportive services and predictors of interest among 118 PC patients receiving ADT. Overall interest in services was associated with lower quality of life (p=0.01). The majority of participants expressed interest in informational services (70%), with a minority (22%) expressing interest in psychosocial services. Interest in psychosocial services was associated with younger age (p=0.02), and shorter duration of ADT (p<0.04), but was unrelated to psychological distress or social support. Although most men (68%) reported that they would prefer not to take medication for depression, 75% would do so if advised by their physician. Overall, results suggest that PC patients on ADT prefer individualized informational support. Substantial interest (61%) in Oncolink, an internet‐based informational resource, suggests the Internet may provide an acceptable mode of service delivery. Health care providers should consider integrating increased informational support into routine care and, more generally, consider patient preferences in prioritizing and designing support services.
