This study aimed to explore functional deficits and perceived quality of life (QoL) among cancer survivors. Sixty-six participants completed the Post Cancer Outcome Survey developed for the purpose of this study. The results indicated (1) modest to moderate degrees of functional deficits in 28 of the 70 items measuring areas of occupation, performance skills, body functions, and psychosocial well-being within the first year after cancer treatment; (2) significantly lower perceived QoL during the first year of survivorship compared with that before diagnosis, at present, and 5 yr hereafter (p < .001); (3) significant moderate negative correlations between the reported functional deficits and QoL (r_s = –.45 to –.57); and (4) a very low percentage of participants (4.5%) receiving occupational therapy during the first year posttreatment. Functional difficulties and compromised QoL identified in this study indicate the need for occupational therapy among cancer survivors. Increasing clients’ awareness of occupational therapy for postcancer care is also suggested.
