Despite a clear relationship between marijuana use and suicidality, little is known about psychological vulnerability factors that may interact with marijuana use to increase suicidality among this high-risk group. The present study examined the moderational impact of social anxiety on the relationship between marijuana use status (current users vs abstainers) and suicidality among 343 community adults. We also examined whether social anxiety moderated the relation between more frequent use (daily vs less frequent) among the 134 current marijuana users. Although social anxiety did not moderate the relation between use status and suicidality, it did moderate the relation between daily use status and suicidality after controlling for a wide range of relevant variables (e.g., demographics, depression, negative affect, and other types of anxiety). The overall model accounted for 59% of the variance in suicidality such that daily marijuana users with elevated social anxiety reported the highest suicidality. Findings highlight the importance of considering social anxiety in efforts to understand and prevent suicidality among this high-risk population.
尽管大麻使用与自杀意念之间存在明显的关系，但对于可能与大麻使用相互作用从而增加高危人群自杀意念的心理脆弱性因素知之甚少。本研究在 343 名社区成年人中，检验了社交焦虑对大麻使用状况（当前使用者与非使用者）与自杀意念之间关系的调节作用。我们还检验了社交焦虑是否调节了 134 名当前大麻使用者中更频繁使用（每日使用与不频繁使用）与自杀意念之间的关系。尽管社交焦虑并没有调节使用状况与自杀意念之间的关系，但在控制了广泛的相关变量（例如人口统计学、抑郁、消极情绪和其他类型的焦虑）后，它确实调节了每日使用状况与自杀意念之间的关系。总体模型解释了自杀意念 59%的变异性，即社交焦虑程度较高的每日使用大麻者报告的自杀意念最高。研究结果强调了在理解和预防高危人群自杀意念方面，考虑社交焦虑的重要性。
