Abstract：
The present meta-analytic study examined the association between alexithymia and psychoactive substance use. Studies published from 1988 to August 20, 2022 were identified by a systematic search and 168 eligible studies were included in five meta-analyses. Results showed that (1) the correlation between substance use and alexithymia is small but significant (r = 0.177); (2) substance users have substantially higher alexithymia than nonusers (g = 0.545); (3) alexithymic participants have significantly but slightly higher levels of substance use than non-alexithymics (g = 0.242); (4) substance users are significantly but only slightly more likely to be alexithymic than nonusers (OR = 2.392); and (5) alexithymic individuals are not more likely to be substance users than non-alexithymics. Larger effects were observed among samples diagnosed with substance use disorder (SUD), and the use of depressants, alcohol, opiates, and illicit stimulants had stronger relation to alexithymia. We found a tendency for a larger association with problematic use as compared to other indicators (e.g., frequency and duration) of substance use. Among the components of alexithymia, difficulties in identifying feelings has the strongest association with substance use. Our findings support clinical practice by suggesting the improvement of emotion regulation in SUD.
摘要：
本荟萃分析研究检查了述情障碍与精神活性物质使用之间的关系。通过系统搜索确定了1988年至2022年8月20日发表的研究，并在5项荟萃分析中纳入了168项符合条件的研究。结果表明：（1）物质使用与述情障碍之间的相关性很小，但显着（r=0.177）；（2）物质使用者的述情障碍明显高于非使用者（g=0.545）；（3）述情参与者的物质使用水平显着，但略高于非述情者（g=0.242）；（4）物质使用者显着，但非述情者的可能性仅略高于3。在诊断为物质使用障碍（SUD）的样本中观察到较大的影响，以及抑制剂的使用，酒精,阿片类药物,非法兴奋剂与述情障碍有更强的关系。与其他指标相比，我们发现与有问题的使用存在更大关联的趋势(例如，频率和持续时间)的物质使用。在述情障碍的组成部分中，识别情感的困难与物质使用有最强烈的联系。我们的发现通过建议改善SUD的情绪调节来支持临床实践。
