Methamphetamine use disorder is a major mental health issue worldwide. An implicit attitude is a potential way to understand the paradoxical behavior of substance use and has not been fully investigated for methamphetamine users. Depression is a common comorbidity for methamphetamine users. Little is known about the moderating effects of depression on the associations between implicit attitudes and addictive behavior in methamphetamine users. The aims of this study were to examine the associations of implicit attitudes with methamphetamine-dependent behavior and the moderation of depression in these associations.
One-hundred and fifty methamphetamine users were enrolled. Epidemiological data, methamphetamine dependence severity, and implicit attitudes were collected.
The results showed that participants have positive implicit attitudes toward methamphetamine and that the implicit attitude is positively related to dependence severity. Depressive methamphetamine users have greater levels of positive implicit attitudes and dependence severity. Furthermore, depression positively moderates the relationships between implicit attitudes and use behavior.
These results highlight the importance of implicit attitudes and depression for methamphetamine dependence and indicate that depression can strengthen the relationship between implicit attitudes and methamphetamine-use behavior. Therefore, both implicit attitudes and depression are areas to be addressed in the treatment of methamphetamine use disorder.
甲基苯丙胺使用障碍是全球主要的心理健康问题。内隐态度是理解物质使用矛盾行为的一种潜在方式，且尚未针对甲基苯丙胺使用者进行充分研究。抑郁症是甲基苯丙胺使用者常见的共病。关于抑郁症对甲基苯丙胺使用者内隐态度与成瘾行为之间关联的调节作用知之甚少。本研究的目的是检验内隐态度与甲基苯丙胺依赖行为之间的关联以及抑郁症在这些关联中的调节作用。
招募了150名甲基苯丙胺使用者。收集了流行病学数据、甲基苯丙胺依赖严重程度和内隐态度。
结果显示，参与者对甲基苯丙胺持有积极的内隐态度，且内隐态度与依赖严重程度呈正相关。患有抑郁症的甲基苯丙胺使用者具有更高水平的积极内隐态度和依赖严重程度。此外，抑郁症正向调节内隐态度与使用行为之间的关系。
这些结果凸显了内隐态度和抑郁症对甲基苯丙胺依赖的重要性，并表明抑郁症会加强内隐态度与甲基苯丙胺使用行为之间的关系。因此，内隐态度和抑郁症都是治疗甲基苯丙胺使用障碍时需要关注的方面。
