This study aimed to examine the associations among functiol impairments, strain and depressive symptoms for caregivers of individuals with brain tumour and other cancers. Sixty-three caregivers (71% female) of individuals with brain tumour (n = 27) and other cancers (n = 36) were recruited from community services. Participants rated their level of depressive symptoms and strain and the functiol impairments of the individual with cancer. Overall, approximately 25% of the total caregiver sample was in the clinical range for depressive symptoms. For caregivers of individuals with brain tumour, strain was significantly related to depressive symptoms (r = .57) and the individual's functiol impairments (r = -.58); however, level of depressive symptoms was not significantly related to functiol impairments (p > .05). For caregivers of individuals with other cancer, level of depressive symptoms was significantly correlated with strain (r = .50) and their relatives' degree of cognitive, interpersol and emotiol difficulties (r = -.36-.46), but not with activities of daily living (p > .05). In a multivariate alysis involving all the caregivers, strain predicted depressive symptoms (R2 = .32, p < .001) after controlling for gender and cancer type. In addition, strain was found to significantly mediate the effects of the interpersol and emotiol difficulties of individuals with cancer on caregiver depressive symptoms. Overall, these findings highlight the need to develop and evaluate strategies for alleviating the role strain associated with supporting individuals with cancer.
