ObjectivesThis study investigates the relationships between mindfulness, depression, and quality of life (QoL) in cancer patients.MethodsA total of 51 cancer patients were assessed with the FreiburgMindfulness Inventory (FFA;Walach et al. 2004), the Hospital Anxiety and Depression Scale (HADS-D; Herrmann et al. 1994), and the Schedule for the Evaluation of Individual Quality of Life -DW (SEI QoLDW; Browne et al. 1997). The nonlinear relationships were analyzed using the instantaneous indirect effect procedure by Hayes and Preacher (2010).ResultsThe relationship between mindfulness and QoL is mediated by depression. Because the relationship between mindfulness and depression is squared, the total effect of mindfulness on QoL is not constant. Increasing the level of mindfulness results in a decrease in its effect on the QoL of cancer patients.ConclusionsCancer patients benefit from mindfulness up to a medium level through a decrease in depression, resulting in higher QoL. Patients with very higher mindfulness show more depressive symptoms, which leads to a neutralization of the effect of mindfulness on QoL.
