A recent meta-analysis showed that poor sleep is both associated with and can directly cause increased aggression. However, no assessment was made of whether objective indicators of sleep and subjective perceptions of sleep contributed equally or differentially to these effects. To test this question, the present meta-analysis directly tests the role of measurement (objective vs subjective) in understanding the relationship between sleep and aggression. By integrating 94 effect sizes using multi-level meta-analysis, the results revealed that aggression is significantly associated with both subjective and objective sleep estimates. Importantly, measurement type emerged as a significant moderator of this relationship, with subjective sleep more strongly associated with aggression than objective sleep. This finding is discussed in relation to the broader implications for how behavioral, or sleep, interventions and research are conducted.

最近的一项荟萃​​分析表明，睡眠不佳既与攻击性增加有关，也可直接导致攻击性增加。然而，没有评估客观的睡眠指标和主观的睡眠感知对这些影响的影响是相同还是不同。为了测试这个问题，本荟萃分析直接测试了测量（客观与主观）在理解睡眠和攻击性之间关系中的作用。通过使用多层次荟萃分析整合 94 个效应大小，结果显示攻击性与主观和客观睡眠估计均显着相关。重要的是，测量类型成为这种关系的重要调节因素，主观睡眠比客观睡眠与攻击性的相关性更强。
