The study's purpose was to improve the psychometric properties of the Youth Asset Survey (YAS).
Longitudinal cohort study with youth and parents recruited via door-to-door canvassing to participate in a 5-wave, 4-year study that assessed prospective associations among youth assets and youth health-related behaviors. Additional test items were added in the last 2 waves of a study to improve the YAS.
Households in randomly selected census tracts located in the Oklahoma City metropolitan area.
Youth and their parents (N = 1111 parent/child dyads). Youth demographic characteristics at wave 4 were mean age = 17.3 (standard deviation = 1.62) years; 53% female, 41% white, 28% Hispanic, 24% African American, and 6% other.
Sixty-eight items assessing 17 youth asset constructs and 8 single items assessing youth risk behaviors.
Confirmatory factor analysis and generalized linear models were conducted to assess construct reliability and predictive validity, respectively.
Cronbach α for the revised asset constructs ranged from .72 to .82, predictive validity was strong, and all revised asset constructs were assessed via 4 items.
Researchers and practitioners have an improved 68-item YAS-Revised, freely available for their use, which measures 17 youth assets with good reliability, validity, and functionality.
本研究旨在提高《青年资产调查》（YAS）的心理测量学特性。
通过挨家挨户上门招募青年和家长参与一项 5 波、4 年的纵向队列研究，该研究评估了青年资产与青年健康相关行为之间的前瞻性关联。在研究的最后 2 波中增加了额外的测试项目，以改进 YAS。
位于俄克拉荷马城大都市区的随机选择的普查区的家庭。
青年及其家长（N=1111 对父母/子女对子）。第 4 波青年人口统计学特征为平均年龄=17.3（标准差=1.62）岁；53%为女性，41%为白人，28%为西班牙裔，24%为非裔美国人，6%为其他种族。
68 项评估 17 项青年资产结构和 8 项单项评估青年风险行为的项目。
进行验证性因素分析和广义线性模型，分别评估结构可靠性和预测有效性。
修订后的资产结构的克朗巴赫α值范围为.72 至.82，预测有效性很强，所有修订后的资产结构均通过 4 项进行评估。
研究人员和从业者拥有一个改进后的 68 项 YAS-Revised，可供他们免费使用，该工具可通过 17 项青年资产测量，具有良好的可靠性、有效性和功能。
