In studies of child development, the combined effect of multiple risks acting in unison has been represented in a variety of ways. This investigation builds upon this preceding work and presents a new procedure for capturing the combined effect of multiple risks. A representative sample of 2,899 British children had their cognitive development measured at 36 and 58 months of age along with 10 potential risks during this period of development. Comparing a cumulative index of these risks against the previously undocumented alternative of confirmatory factor analysis using formative measurement, this study found differences favouring the factor analysis. The factor analysis procedure demonstrated greater predictive power of children's cognitive development while it systematically tested two of the assumptions implicit in cumulative risk indices.
在儿童发展研究中，多种风险协同作用的综合效应以多种方式呈现。本研究在前人工作的基础上，提出了一种新的方法来捕捉多种风险的综合效应。一个有代表性的 2899 名英国儿童样本，在他们的认知发展过程中，在 36 个月和 58 个月时进行了测量，同时还测量了 10 种潜在的风险。将这些风险的累积指数与以前未记录的使用形成性测量的确认性因素分析进行比较，本研究发现，累积指数更有利于因素分析。该因素分析程序显示了对儿童认知发展的更高预测能力，同时系统地检验了累积风险指数中隐含的两个假设。
