Psychometric Properties of the Therapy-Related Symptom Checklist-Children

Leukaemias are the most common type of cancer in children and young people, accounting for 1/3 of all cancers in the population. Most childhood leukaemias are acute lymphocytic leukaemia (ALL), while the rest of the cases are acute myeloid leukaemia (AML). In childhood, ALL peaks at the age of 2-4 years. AML, on the other hand, can be seen throughout childhood and is more common in children under 2 years of age and in adolescents. Chronic leukaemias are rarely seen in children. After the leukaemia is diagnosed and the type of leukaemia is determined, the treatment protocol is decided according to the risk group of the disease. The main treatment for childhood leukaemia is chemotherapy. For children in the high-risk group, high-dose chemotherapy may be given together with stem cell transplantation. Treatment of leukaemias can last 2-3 years with maintenance treatment, depending on the type and risk group. Chemotherapy is known to cause many side effects in both adults and children. The most well-known of these side effects are nausea and vomiting, loss of appetite, weight loss, mucositis, gastrointestinal system changes and fatigue, alopecia, pain, depression. Monitoring and effective management of side effects of chemotherapy is one of the most important aspects of cancer treatment. Symptoms resulting from the use of chemotherapies require careful monitoring to identify adverse side effects on patients. During the diagnosis and treatment process of leukaemia, children experience many symptoms at the same time. When these symptoms are both related to each other and occur at the same time, this is called a symptom cluster. Studies emphasise that multiple symptoms are seen in children and adolescents with cancer. When the literature was analysed, it was seen that there were few studies involving the use of checklists to identify symptoms and symptom management, the sample of which consisted of patients and their parents in Turkey. However, recognising symptom clusters may provide a better understanding of the structure of multiple symptoms and more effective symptom management. In this context, this study aimed to add to the national literature by conducting a Turkish validity and reliability study of a checklist suitable for the use of health professionals in clinics for monitoring the side effects of chemotherapy.
