This report describes the early stages in the development and testing of an instrument, known as the CHIP (Child Health and Illness Profile), for assessing the health of individuals aged 11 through 17. The purpose of the instrument is to assess health in epidemiologic surveys, to determine the existence of systematic differences in health in subpopulations (including the socioeconomically disadvantaged), and to provide a basis for assessing the impact of changes in health services or health policies. An instrument consisting of six domains with 25 subdomains was developed based on the literature, the involvement of focus groups and expert panels, and pretesting in four groups of teenagers known to differ in their health. The results of work with panels of experts suggest that the instrument has content validity. Most domains and subdomains had acceptable reliability as measured by alpha coefficients. Differences in the scores of individuals in the four groups were in the predicted directions, suggesting that the instrument also has construct validity. Additional research is under way to establish other aspects of validity as well as reliability in school populations of adolescents as well as specific clinical settings.
本报告描述了一种名为CHIP（儿童健康与疾病概况）的工具在开发和测试的早期阶段，该工具用于评估11至17岁个体的健康状况。该工具的目的是在流行病学调查中评估健康状况，确定亚人群（包括社会经济地位不利人群）健康方面系统差异的存在，并为评估卫生服务或卫生政策变化的影响提供依据。基于文献、焦点小组和专家小组的参与以及在已知健康状况不同的四组青少年中进行的预测试，开发了一个由六个领域和25个子领域组成的工具。与专家小组合作的结果表明该工具具有内容效度。通过阿尔法系数测量，大多数领域和子领域具有可接受的信度。四组个体得分的差异符合预期方向，表明该工具也具有结构效度。正在进行进一步的研究，以确定该工具在青少年学校人群以及特定临床环境中的效度和信度的其他方面。
