Substance use often co-occurs with both internalizing and externalizing disorders, highlighting the importance of understanding reciprocal relations among problematic drug use and psychopathology. We examined affective (approach and avoidance) motivations for drug use as potential transdiagnostic constructs that relate to symptoms of common clinical disorders.
175 community adults with a lifetime history of drug use reported on their motivations for use, frequency of use, and DSM-5 lifetime psychopathology symptoms. Linear regression was used to examine associations between drug use motivations and psychopathology.
Avoidance motivations for drug use (e.g., using to cope with distress) correlated positively with symptoms of both internalizing and externalizing disorders, borderline personality disorder, and psychiatric comorbidity. In contrast, approach motivations for drug use (e.g., using to get a thrill) correlated only with substance use disorder symptoms. Notably, motivations for drug use continued to show these transdiagnostic associations after accounting for general approach-avoidance motivational tendencies.
These findings suggest that affective motivations for drug use provide a useful framework for conceptualizing substance problems that cuts across traditional dimensions of psychopathology.
物质使用常常与内化性和外化性障碍同时出现，这凸显了理解问题性药物使用与精神病理学之间相互关系的重要性。我们研究了药物使用的情感（趋近和回避）动机，将其作为与常见临床障碍症状相关的潜在跨诊断结构。
175名有药物使用终生史的社区成年人报告了他们的使用动机、使用频率以及《精神疾病诊断与统计手册》第五版（DSM-5）终生精神病理学症状。采用线性回归来研究药物使用动机与精神病理学之间的关联。
药物使用的回避动机（例如，为应对痛苦而使用）与内化性和外化性障碍、边缘型人格障碍以及精神共病的症状呈正相关。相比之下，药物使用的趋近动机（例如，为寻求刺激而使用）仅与物质使用障碍症状相关。值得注意的是，在考虑了一般的趋近-回避动机倾向后，药物使用动机仍显示出这些跨诊断关联。
这些发现表明，药物使用的情感动机为概念化跨越传统精神病理学维度的物质问题提供了一个有用的框架。
