The study used Rasch analysis to investigate the presence of a syndrome of health risk behavior in South African adolescents. A total of 2186 in-school adolescents participated in the study (males = 1077; females = 1119; age range = 12-16 years; median = 13 years). The data are baseline from a longitudinal study of a leisure-based drug abuse and HIV/AIDS prevention program at Mitchell's Plain in Cape Town, South Africa. The adolescents completed a self-report measure on various health risk vulnerabilities, including use of alcohol, tobacco and other drugs (ATOD), co-occurrence of penetrative sex with use of ATOD, health related self-efficacy, personal beliefs about health, peer perceptions, and use of contraceptives. The Rasch analysis calibrated data on 50 items from the aforesaid conceptually distinct health risk domains. Infit and Outfit mean square statistics and principal components analysis of the standardized residuals suggested a fit of the data to the unidimensional Rasch measurement model. The findings support a syndrome view of health risk in teenagers as proposed by problem behavior theory.
该研究采用拉施分析来调查南非青少年中健康风险行为综合征的存在情况。共有2186名在校青少年参与了该研究（男性 = 1077名；女性 = 1119名；年龄范围 = 12至16岁；中位数 = 13岁）。这些数据是南非开普敦米切尔平原一项基于休闲的药物滥用和艾滋病毒/艾滋病预防项目纵向研究的基线数据。青少年们完成了一项关于各种健康风险易感性的自我报告测量，包括酒精、烟草和其他药物（ATOD）的使用、与ATOD使用同时发生的 penetrative性行为、与健康相关的自我效能感、对健康的个人信念、同伴认知以及避孕药具的使用。拉施分析对上述概念上不同的健康风险领域中50个项目的数据进行了校准。标准化残差的拟合度和 outfit均方统计以及主成分分析表明数据符合单维拉施测量模型。研究结果支持了问题行为理论所提出的青少年健康风险综合征观点。
