Progress in the science and practice of health psychology depends on the systematic synthesis of quantitative psychological evidence. Meta-analyses of experimental studies have led to important advances in understanding health-related behaviour change interventions. Fundamental questions regarding such interventions have been systematically investigated through synthesising relevant experimental evidence using standard pairwise meta-analytic procedures that provide reliable estimates of the magnitude, homogeneity and potential biases in effects observed. However, these syntheses only provide information about whether particular types of interventions work better than a control condition or specific alternative approaches. To increase the impact of health psychology on health-related policy-making, evidence regarding the comparative efficacy of all relevant intervention approaches – which may include biomedical approaches – is necessary. With the development of network meta-analysis (NMA), such evidence can be synthesised, even when direct head-to-head trials do not exist. However, care must be taken in its application to ensure reliable estimates of the effect sizes between interventions are revealed. This review paper describes the potential importance of NMA to health psychology, how the technique works and important considerations for its appropriate application within health psychology.

健康心理学和行为医学中的网络荟萃分析：入门

健康心理学的科学和实践的进步取决于定量心理学证据的系统综合。对实验研究的荟萃分析已导致在理解与健康有关的行为改变干预措施方面的重要进展。通过使用标准的成对荟萃分析程序综合相关的实验证据，系统地研究了有关此类干预措施的基本问题，这些方法提供了对观察到的效应的大小，同质性和潜在偏差的可靠估计。但是，这些综合仅提供有关特定类型的干预是否比控制条件或特定替代方法更有效的信息。为了增加健康心理学对与健康有关的决策的影响，关于所有相关干预方法（可能包括生物医学方法）的比较功效的证据是必要的。随着网络荟萃分析（NMA）的发展，即使不存在直接的头对头试验，这种证据也可以得到综合。但是，在应用中必须注意确保对干预之间的效应大小进行可靠的估计。这篇综述文章描述了NMA对健康心理学的潜在重要性，该技术的工作原理以及在健康心理学中适当应用的重要考虑因素。在应用中必须注意确保对干预之间的效应大小进行可靠的估计。这篇综述文章描述了NMA对健康心理学的潜在重要性，该技术的工作原理以及在健康心理学中适当应用的重要考虑因素。在应用中必须注意确保对干预之间的效应大小进行可靠的估计。这篇综述文章描述了NMA对健康心理学的潜在重要性，该技术的工作原理以及在健康心理学中适当应用的重要考虑因素。
