Biological, psychological, and social factors all influence a child's sense of pain. Pain beliefs can have a significant impact on a person's perception of pain and adherence to treatment. As a result, pain management requires a thorough examination of the factors that influence pain perception. Coping is a cognitive and behavioral response to conditions and threats based on by personal or environmental factors. Children who do not have adequate coping mechanisms suffer from more severe pain. As a result, dealing with pain is a crucial part of pain management. This highlights the need of assessing pain coping in children when treating chronic pain. The purpose of this study is to show that the Turkish version of the Pain Coping Questionnaire (PCQ), which assesses children's pain coping techniques, is valid and reliable, as well as to ensure that it is culturally appropriate.

Pain is a biopsychosocial term that comprises sensory, cognitive, and emotional factors. The biological, psychological, and cognitive aspects of pain are all present. Pain symptoms and comorbid symptoms are biological characteristics; anxiety, depression, and rage are psychological characteristics; and the ability to cope, catastrophize, and manage pain are cognitive characteristics. As a result, pain is influenced by a person's past experiences and beliefs. Pain that lasts longer than three months is referred to as chronic pain. A major issue is the high prevalence of chronic pain in children. Children with chronic pain have a lower quality of life than their healthy peers. Furthermore, this effect is unrelated to the degree of biological damage. Some children are more sensitive to pain than others, regardless of the severity of the condition. Because psychological, cognitive, and social variables influence an individual's perception of pain in addition to biological tissue damage.

The use of coping techniques in children varies based on the diagnosis, age, and gender of the child, according to the literature. Inadequate coping techniques are linked to a lower quality of life and increased pain severity. As a result, pain assessment in children with chronic pain should be done within a biopsychosocial framework. Various assessments have been developed to assess children's pain tolerating abilities. The Pain Coping Questionnaire (PCQ) was created to evaluate problem-focused, emotional-focused, and avoidance-focused coping strategies in children. It's the most commonly used scale for assessing children's coping techniques. The purpose of this study is to show that the Turkish version of the Pain Coping Questionnaire is valid and reliable (PCQ).
