Effectiveness of creative arts therapy for adult patients with cancer: a systematic review and meta-analysis

Objectives This systematic review and meta-analysis aimed to assess the effectiveness of creative arts therapy (CAT) interventions on the health outcomes of adult patients with cancer. Methods A comprehensive search was conducted in six databases from their inception to June 10, 2023, with no restrictions on sex, age, cancer type, cancer stage, or treatment type. The Cochrane Risk of Bias (RoB2) tool for randomized controlled trials (RCTs) and the equivalent tool for non-RCTs (ROBINS-I) were used to assess the risk of bias. Meta-analyses were conducted to pool estimates of the effects of CAT on patients' health-related outcomes. A narrative synthesis of outcomes was performed where meta-analysis was not appropriate. Results A total of 25 studies (8 RCTs and 17 quasi-RCTs) involving 1489 cancer patients and survivors were included in the final data analysis. Most studies focused on patients with mixed cancer diagnoses who were undergoing active chemotherapy treatment. Most studies utilized painting, drawing, and/or sculpting as CAT interventions. The overall risk of bias in the included studies was moderate to high. Meta-analysis demonstrated a significant improvement in quality of life (SMD with 95% CI = 17.50, 10.05-24.95, P =.0000) and the social aspect of quality of life in cancer patients (SMD with 95% CI = 03.1 (0.06-0.55), P = .01), but no significant effects were found for depressive symptoms and coping strategies among patients who participated in CAT compared to control groups. Narrative analysis and non-RCTs suggested the potential of CAT in reducing levels of depression and anxiety, as well as improving self-image, hope, emotional expression/state, and processing in patients with cancer. However, inconsistent findings were reported regarding the effectiveness of CAT interventions on fatigue, spirituality, and psychosomatic distress/symptom intensity. Conclusion The findings indicated significant and potential benefits of CAT for individuals with cancer, primarily related to quality of life. However, caution is needed in interpreting these findings due to limitations in the methodologies utilized in the included studies. Further large-scale RCTs are needed to examine the effectiveness of CAT on health outcomes, particularly in relation to self-image, hope, and emotional expression/state and processing among patients with cancer or those in palliative care.
