The aims of the study were: (a) to propose focal refinements to the cold pressor test (CPT) for the pediatric population, contributing to the development of subjective and behavioral norms; (b) to analyze the influence of personal (gender, age, and skin-fold thickness), and psychological (anxiety, depression, internalization, and externalization) variables on pain perception and its correlation with room temperature.
After a phase of adaptation in a water bath (24-27 degrees C), the child immersed one arm in cold water (10 degrees C) and reported pain threshold and tolerance.
The test was conducted on 141 healthy children. Pain tolerance was reached within the first minute by 50% of the children. Pain intensity affected the children's emotional status. Older children tolerated pain for longer. Gender, psychological, and environmental variables did not influence pain perception.
This study provides methodological refinements to the CPT contributing to the development of norms for children.
本研究旨在：(a) 为儿科人群提出冷加压测试 (CPT) 的焦点细化，为制定主观和行为规范做出贡献；(b) 分析个人（性别、年龄和皮褶厚度）和心理（焦虑、抑郁、内化和外化）变量对疼痛感知的影响及其与室温的相关性。
在水疗（24-27 度 C）适应阶段后，孩子将一只手臂浸入冷水（10 度 C）并报告疼痛阈值和耐受度。
该测试在 141 名健康儿童中进行。50%的儿童在第一分钟内达到疼痛耐受。疼痛强度影响儿童的情绪状态。年龄较大的儿童能耐受更长时间的疼痛。性别、心理和环境变量并不影响疼痛感知。
本研究为 CPT 提供了方法学上的细化，为儿童制定规范做出了贡献。
