Individuals with an autism spectrum disorder (ASD) are thought to encounter planning difficulties, but experimental research regarding the mastery of planning in ASD is inconsistent. By means of a meta-analysis of 50 planning studies with a combined sample size of 1755 individuals with and 1642 without ASD, we aim to determine whether planning difficulties do exist and which factors contribute to this. Planning problems were evident in individuals with ASD (Hedges'g = 0.52), even when taking publication bias into account (Hedges'g = 0.37). Neither age, nor task-type, nor IQ reduced the observed heterogeneity, suggesting that these were not crucial moderators within the current meta-analysis. However, while we showed that ASD individuals encounter planning difficulties, the bias towards publishing positive findings restricts strong conclusions regarding the role of potential moderators.
患有自闭症谱系障碍（ASD）的个体被认为存在规划困难，但关于ASD患者规划能力掌握情况的实验研究结果并不一致。通过对50项规划研究进行荟萃分析，这些研究的样本总量为1755名患有ASD的个体和1642名未患ASD的个体，我们旨在确定规划困难是否确实存在以及哪些因素导致了这一情况。ASD个体存在明显的规划问题（赫奇斯g值=0.52），即便考虑到发表偏倚时也是如此（赫奇斯g值=0.37）。年龄、任务类型和智商均未减少观察到的异质性，这表明在当前的荟萃分析中，这些并非关键的调节因素。然而，虽然我们表明ASD个体存在规划困难，但倾向于发表阳性结果的偏差限制了我们就潜在调节因素的作用得出强有力的结论。
