Validation of the English Version of the Pain Interference Index and the Pain Rating Scale in Children, Adolescents, and Adults With Chronic Illness and Their Parents

About the study


– Assessing pain levels is important to improve treatments for different illnesses. Most pain rating scales are used to determine pain levels in adults. Pain is also a common symptom among children who have cancer. Those who have genetic conditions that may lead to cancer may also have pain symptoms. However, the pain scales used for adults have not been fully tested in children and young adults. As a result, they may not be as accurate. Researchers want to test pain rating scales in children and young adults who have cancer and genetic conditions that can lead to cancer.


– To study the effectiveness of pain rating scales given to children and adults with Sickle Cell Disease (SCD),cancer, and related genetic conditions.


– Adults 18 and 34 years of age and older who have SCD, cancer, or other genetic conditions that can lead to cancer.


Participants with SCD, cancer or related genetic conditions will fill out four questionnaires. These questionnaires will ask about pain levels and how much pain interferes with daily life.
Pain treatments will not be provided as part of this study.
