This study assessed self-perception as a long-term predictor of relative changes in problems related to alcohol and marijuana use in early adulthood. Self-report questionnaires were completed by a community sample of 124 individuals in the Southeastern United States who were followed longitudinally from age 19 to 27. More problems due to substance use at age 27 were predicted by participants’ negative perceptions of their social acceptance, romantic appeal, and self-worth. Predictions remained after accounting for potential confounds including gender, income, and baseline substance use problems at age 19. Social avoidance and distress in new situations at age 19 mediated the relationship between self-perception and relative changes in substance use problems, such that increases in substance use problems from age 19 to 27 were potentially explainable by the linkage of negative self-perceptions to social avoidance and distress in new situations.

成年早期物质使用问题的自我认知和相对增加

这项研究评估了自我感知作为成年早期酒精和大麻使用相关问题相对变化的长期预测指标。自我报告问卷由美国东南部的 124 名社区样本完成，这些人从 19 岁到 27 岁进行纵向跟踪。 参与者对他们的社会接受度、浪漫的负面看法预测了 27 岁时因物质使用而导致的更多问题吸引力和自我价值。在考虑了潜在的混杂因素后，预测仍然存在，包括 19 岁时的性别、收入和基线物质使用问题。 19 岁时在新情况下的社交回避和痛苦介导了自我认知与物质使用问题的相对变化之间的关系，
