“…Exploring and expressing thoughts and feelings are considered core aspects of psychotherapy , and there is evidence to suggest that supportive‐expressive interventions, helping cancer patients express their cancer‐related thoughts and emotions, may improve both psychological and physical health outcomes . One mode of emotional expression linked with beneficial health outcomes is writing , and the early research by Pennebaker and colleagues demonstrated that writing as little as 15–20 min for 3 days about emotions associated with a traumatic event could lead to improvements in both psychological and biological health .…”

Objective: This study aimed to evaluate the effectiveness of expressive writing intervention (EWI) for improving psychological and physical health in cancer patients and survivors.Methods: We searched databases and existing reviews for randomized controlled studies published between 1986 and 2014 that evaluated the effects of EWI on psychological and physical health outcomes. We computed and combined effect sizes and examined the role of methodological characteristics.Results: From 223 unique citations, we identified 16 independent randomized controlled trials published from 1999 to 2014, examining the effect of EWI on a range of psychological and physical health outcomes. No statistically significant effects were found for any of the individual or combined psychological (Hedges's g: 0.04; 95% CI, À0.06 to 0.14; p = 0.42), physical (0.08; 95% CI, À0.05 to 0.20; p = 0.22), or quality-of-life outcomes (0.09; 95% CI, À0.05 to 0.24; p = 0.22). The results were unaffected by differences in study characteristics, for example, type of control condition, study setting, cancer type, and overall study quality ratings. Results from a subset of studies indicated a possible moderating effect of social constraints, suggesting that participants experiencing low levels of emotional support may be more likely to benefit from EWI.Conclusions: Our results do not support the general effectiveness of EWI in cancer patients and survivors. However, given the practical and inexpensive intervention, it is possible that even small effects in subgroups of patients could be clinically relevant, and future studies are recommended to test the effects of potential moderators, including pre-intervention distress levels and context-dependent factors such as emotional support.
