BackgroundStudies of individuals with non-cancer-related chronic pain find that higher levels of psychological flexibility (PF) are associated with less distress, better functioning, and a better response to treatment. People diagnosed with cancer are at a significantly increased risk of developing chronic cancer-related pain, the presence of which is associated with poorer health outcomes. Little is known about whether PF is applicable to cancer pain. The current study investigates the relationship between chronic cancer-related pain, distress and functioning, and three theoretical processes proposed by the PF model: pain acceptance, present-moment focus, and committed action.MethodsAdults (n = 246) with a cancer diagnosis (current or previous), and living in Sweden, completed an online survey involving standardized measures of cancer-related pain (intensity and impairment), depression, fatigue, PF and social stigma.ResultsModerate to strong correlations were found between PF and all variables. In regression analyses, PF, and particularly pain acceptance, accounted for a large and significant proportion of the observed variance in depression, pain-related and overall functioning, after controlling for cancer status, pain intensity and social stigma.ConclusionConsistent with studies of non-cancer-related pain, higher levels of PF were strongly associated with lower levels of distress and better functioning in individuals with cancer-related pain. Further studies are needed to further explore these relationships and to determine whether psychosocial treatments targeting PF may be of benefit to people with chronic cancer-related pain.SignificanceThis study explores the relationship between cancer-related pain (intensity and impairment), depression, fatigue, overall functioning, social stigma and PF. The findings suggest that higher levels of PF are associated with lower levels of distress and improved functioning in chronic cancer-related pain, after controlling for cancer status (current, in remission), pain intensity and social stigma.© 2022 The Authors.
