We report a quality effects meta-analysis on studies from the period 1966-2016 measuring either (a) lucid dreaming prevalence (one or more lucid dreams in a lifetime); (b) frequent lucid dreaming (one or more lucid dreams in a month) or both. A quality effects meta-analysis allows for the minimisation of the influence of study methodological quality on overall model estimates. Following sensitivity analysis, a heterogeneous lucid dreaming prevalence data set of 34 studies yielded a mean estimate of 55%, 95% C. I. [49%, 62%] for which moderator analysis showed no systematic bias for suspected sources of variability. A heterogeneous lucid dreaming frequency data set of 25 studies yielded a mean estimate of 23%, 95% C. I. [20%, 25%], moderator analysis revealed no suspected sources of variability. These findings are consistent with earlier estimates of lucid dreaming prevalence and frequent lucid dreaming in the population but are based on more robust evidence.
我们报告了一项关于1966年至2016年期间研究的质量效应荟萃分析，这些研究测量了以下两者之一：（a）清醒梦发生率（一生中至少做过一次清醒梦）；（b）频繁清醒梦（一个月内至少做过一次清醒梦）或两者皆有。质量效应荟萃分析能够将研究方法质量对总体模型估计的影响降至最低。经过敏感性分析，一个由34项研究组成的异质性清醒梦发生率数据集得出的平均估计值为55%，95%置信区间为[49%，62%]，其中调节因素分析表明，对于可疑的变异来源没有系统偏差。一个由25项研究组成的异质性清醒梦频率数据集得出的平均估计值为23%，95%置信区间为[20%，25%]，调节因素分析未发现可疑的变异来源。这些发现与之前关于人群中清醒梦发生率和频繁清醒梦的估计一致，但基于更有力的证据。
