Adolescents undergoing cancer treatment frequently experience a combination of physical symptoms and psychosocial stressors that negatively affect their emotional well-being, anxiety levels, and ability to regulate emotions. Difficulties in emotion regulation may intensify perceived symptom burden and interfere with treatment adherence and overall quality of life. Art-based interventions offer developmentally appropriate, expressive, and non-invasive strategies to support emotional regulation in this population.
This study is designed as a single-blind, parallel-group randomized controlled trial to examine the effectiveness of an art-based emotion regulation program in adolescents receiving cancer treatment. The study will be conducted between January 30, 2026 and March30, 2027 at the Pediatric Hematology-Oncology units of Gazi University Health Application and Research Center and Etlik City Hospital.
A total of 60 adolescents aged 10-18 years who have been receiving cancer treatment for at least six months will be enrolled and randomly assigned to either the intervention group (n=30) or the control group (n=30). Stratified block randomization based on age and gender will be performed by an independent statistician using an online randomization tool. Outcome assessors will be blinded to group allocation.
The intervention group will participate in a 4-week art-based emotion regulation program consisting of progressive muscle relaxation exercises, emotion-color mapping activities, and gratitude mandala practices. During the first week, adolescents will receive a progressive muscle relaxation video and complete the first session together with the researcher. They will then be asked to practice the exercise at least twice weekly throughout the program. Emotion-color mapping activities will be conducted during weeks 1-3 to help adolescents visually express and monitor changes in emotional states and symptom intensity. In the second week, a gratitude mandala activity will be added to enhance awareness of positive emotions. Weekly follow-up discussions will be conducted to support engagement and reflection. In the fourth week, relaxation exercises will continue, emotion-color maps will be reviewed for change, and post-test assessments will be completed.
The control group will receive routine hospital care without any additional intervention. Both groups will complete the same assessment tools at baseline and at the end of the fourth week.
Primary and secondary outcomes will be measured using the State Anxiety Inventory for Children, the Emotion Regulation Questionnaire for Children and Adolescents, and the Pediatric Symptom Screening Tool (SSPedi). The findings of this study are expected to provide evidence for the effectiveness of art-based emotion regulation interventions as a supportive, feasible, and non-pharmacological approach in adolescent oncology care.
