操作效度可能受到许多因素的影响，包括实验程序的特定方面。荟萃分析是一个理想的工具，用于评估影响因素的操作，因为它能够等同，组合，并衡量不同的实验程序对给定的操作的影响。通过采用韦尔滕情绪操纵的元分析实验证明了元分析的这种使用。这种操纵被批评为创造实验性需求。与实验需求相关的程序包括是否使用诚实或欺骗性的封面故事，以及是否使用自我报告或非自我报告的操纵检查措施。当使用欺骗性（与诚实）的封面故事和使用非自我报告（与自我报告）的操纵检查措施时，效果大小较小。讨论关注如何韦尔滕操作可能会受到影响，以及如何荟萃分析可能会被用来评估影响操作有效性的因素。
Manipulation validity may be influenced by many factors, including specific aspects of experimental procedure. Meta-analysis is an ideal tool for assessing factors that influence manipulations because it is capable of equating, combining, and gauging the impact of different experimental procedures on a given manipulation. This use of meta-analysis is demonstrated by meta-analyzing experiments employing the Velten mood manipulation. This manipulation has been criticized for creating experimental demand. Procedures relevant to experimental demand include whether an honest or deceptive cover story is used and whether a self-report or non-self-report manipulation check measure is used. Effect sizes are smaller when a deceptive (vs. honest) cover story is used and when a non-self-report (vs. self-report) manipulation check measure is used. Discussion concerns how the Velten manipulation may be compromised and how meta-analysis may be employed to evaluate factors influencing manipulation validity.
