This article looks at the use of large health records datasets, typically linked with other data sources, and their use in mental health research. The most comprehensive examples of this kind of big data are typically found in Scandinavian countries however there are also many useful sources in the UK. There are a number of promising methodological innovations from studies using big data in UK mental health research, including: hybrid study designs, examples of data linkage and enhanced study recruitment. It is, though, important to be aware of the limitations of research using big data, particularly the various analysis pitfalls. We therefore caution against throwing out the methodological baby with the bathwater and argue that other data sources are equally valuable and ideally research should incorporate a range of data.
本文探讨了大型健康记录数据集（通常与其他数据源相链接）在心理健康研究中的应用。这类大数据最全面的例子通常出现在斯堪的纳维亚国家，不过英国也有许多有用的数据源。在英国心理健康研究中，使用大数据的研究带来了一些有前景的方法创新，包括：混合研究设计、数据链接示例以及强化研究招募。然而，必须意识到使用大数据进行研究的局限性，尤其是各种分析陷阱。因此，我们告诫不要因噎废食，认为其他数据源同样有价值，理想情况下研究应纳入一系列数据。
