目的：评估美国儿科学会伤害预防项目安全调查（TIPP-SS）在衡量伤害预防实践方面的信度和效度。设计：使用重测方法测量可靠性。有效性是通过比较家长填写的 TIPP-SS 和调查时在参与者家中进行的家庭安全审核的结果来衡量的。设置：两个芝加哥公立学校幼儿教育计划站点。参与者：88 个家庭（44 个讲英语和 44 个讲西班牙语），其中有 3 至 5 岁的孩子参加 A 点或 B 点芝加哥公立学校幼儿教育计划。参与者在不同地点之间平均分配。干预：对于可靠性研究，主要看护者完成了 TIPP-SS 两次，间隔 14 至 24 天。对于有效性研究，主要护理人员在家访期间完成了 TIPP-SS，其中研究助理完成了家庭安全审核。总共完成了 44 次家访，其中 22 次使用西班牙语，22 次使用英语。 结果测量：TIPP-SS 的重测信度和效度。比较各个项目和整个调查的结果是否一致。结果：伤害预防项目安全调查是可靠的，但无效。伤害预防项目安全调查是伤害预防知识和实践概念的良好衡量标准（Cronbach alpha = 0.869）。外部可靠性也得到统计支持（P=.40）。伤害预防项目安全调查并不是伤害预防行为的有效衡量标准。基于观察数据的项目的有效性较差（英语中的 Pearson r=0.287；西班牙语中的 Pearson r=-0.449）。家长报告数据的有效性要强得多（英语中的 Pearson r=0.689；西班牙语中的 Pearson r=1.00）。 结论：结果表明 TIPP-SS 衡量的是知识和态度而不是行为。父母通常知道期望的行为或状况，并报告这些行为或状况，而不是实际状况或行为。这表明，应该继续寻求开发一种有效的家庭伤害预防行为评估工具，并以仔细解决潜在工具的有效性和可靠性的方式进行。
Objective: To evaluate reliability and validity of The Injury Prevention Project Safety Survey (TIPP-SS) of the American Academy of Pediatrics in measuring injury prevention practices.Design: Reliability was measured using the test-retest method. Validity is measured comparing results of parent-completed TIPP-SSs and a home safety audit conducted in the participants' homes at the time of survey.Setting: Two Chicago Public School Early Childhood Education program sites.Participants: Eighty-eight families (44 English speaking and 44 Spanish speaking) with a child aged 3 to 5 years attending a site A or B Chicago Public School Early Childhood Education program. Participants were split evenly between sites.Intervention: For the reliability study, primary caregivers completed TIPP-SS twice, 14 to 24 days apart. For the validity study, primary caregivers completed TIPP-SS during a home visit in which a research assistant completed a home safety audit. A total of 44 home visits were completed, 22 in Spanish and 22 in English.Outcome Measures: Test-retest reliability and validity of TIPP-SS. Results are compared for agreement of individual items and the whole survey.Results: The Injury Prevention Project Safety Survey is reliable but not valid. The Injury Prevention Project Safety Survey is a good measure of the concept of injury prevention knowledge and practice (Cronbach alpha=0.869). External reliability was statistically supported as well (P=.40). The Injury Prevention Project Safety Survey is not a valid measure of injury prevention behaviors. Validity was poor for items based on observed data (Pearson r=0.287, in English; Pearson r=-0.449, in Spanish). Validity was much stronger for parent report data (Pearson r=0.689, in English; Pearson r=1.00, in Spanish).Conclusions: Results suggest that TIPP-SS measures knowledge and attitudes rather than behavior. Parents are often aware of the desired behavior or condition and report those instead of actual conditions or behaviors. This suggests that the quest to develop a valid home-based, injury prevention, behavior assessment tool should continue and be done in a way that carefully addresses potential instruments' validity and reliability.
