Evaluate the psychometric properties of child- and parent-report versions of the four-item Abdominal Pain Index (API) in children with functional abdominal pain (FAP) and healthy controls, using a revised scoring method that facilitates comparisons of scores across samples and time.
Pediatric patients aged 8-18 years with FAP and controls completed the API at baseline (N = 1,967); a subset of their parents (N = 290) completed the API regarding the child's pain. Subsets of patients completed follow-up assessments at 2 weeks (N = 231), 3 months (N = 330), and 6 months (N = 107). Subsets of both patients (N = 389) and healthy controls (N = 172) completed a long-term follow-up assessment (mean age at follow-up = 20.21 years, SD = 3.75).
The API demonstrated good concurrent, discriminant, and construct validity, as well as good internal consistency.
We conclude that the API, using the revised scoring method, is a useful, reliable, and valid measure of abdominal pain severity.
采用一种便于跨样本和时间比较分数的修订评分方法，评估功能性腹痛（FAP）儿童和健康对照中儿童报告版和家长报告版的四项腹痛指数（API）的心理测量特性。
8至18岁的FAP儿科患者和对照在基线时完成了API（N = 1967）；他们的一部分家长（N = 290）完成了关于孩子疼痛的API。部分患者在2周（N = 231）、3个月（N = 330）和6个月（N = 107）时完成了随访评估。部分患者（N = 389）和健康对照（N = 172）完成了长期随访评估（随访时的平均年龄 = 20.21岁，标准差 = 3.75）。
API显示出良好的同时效度、区分效度和结构效度，以及良好的内部一致性。
我们得出结论，采用修订评分方法的API是一种有用、可靠且有效的腹痛严重程度测量工具。
