Survivor distress is well represented in the literature, but less is known about survivors' concerns and how these relate to adaptation. Using a newly designed Survivorship Concern Scale, we examined concerns and their relationship to psychosocial adaptation among recent breast cancer (BC) survivors. One hundred forty-three stage 0-III BC survivors completed an online assessment including the Survivorship Concern Scale (0-3 scale; alpha=0.91), unmet needs, quality of life (QoL), and anxiety and depressive symptoms within 1year of end of treatment. Participants were predominately white (76%), middle-aged (51years), married (70%), and college educated (79%). Eighty-two percent were stage I or II at diagnosis. Mean degree of survivorship concern was moderate (M=1.75, SD=0.70) though variable (range=0.12-3.00). Survivorship concerns were not significantly related to disease, treatment, or demographic variables except income (p=0.02). Degree of survivorship concern was significantly associated with all indices of psychosocial adaptation: unmet need (r=0.50), physical and mental QoL (r=-0.32 and r=-0.32, respectively), depressive symptoms (r=0.21), and anxiety symptoms (r=0.51; all p<0.001). Binary logistic regression suggested that each one-point increase in degree of average concern increased the odds for elevated depressive symptoms by 2.83 (p=0.03) and increased the odds of elevated anxiety symptoms by 3.69 (p<0.001). Survivorship concerns in the year following treatment are moderate but variable. Concerns are associated with QoL, unmet need, and psychosocial adaptation. Adequately addressing concerns may be a way to improve psychosocial outcomes early in the survivorship trajectory.
