In an experimental randomized controlled trial, a total of 60 children aged 7-13 years previously diagnosed with malignancy together with their parents were assigned randomly either to an experimental (30 patients) or a control group (30 patients) in 2017 in Iraq. The patients in the experimental group participated in painting and handcrafting group art therapy (creative art therapy) conducted by a professional fine artist for a one-month period. The dimensions of health-related quality of life in both study groups were measured through the KIDSCREEN-10 Index after project completion.
