The purpose of this study was to assess the implications of depression in a sample of university students, particularly relating to impulse control disorders. While previous studies have shown high rates of depression among university students, no study to date has assessed whether levels of depression show associations with the incidence of impulse control disorders in this population.
In all, 6000 students participated in the College Student Computer Use Survey. A total of 1717 students completed the scales of interest for this analysis. Participants were assigned to groups based on depression scores: severe (N = 75), mild/moderate (N = 647) and none (N = 995). The three groups were assessed using analysis of variance (ANOVA) or chi-square test. A multinomial logistic regression analysis was used to elucidate associations between depression and impulse control disorder diagnoses.
Groups differed across demographic, health and academic variables. The severe depression group reported higher rates of skin-picking disorder, compulsive sexual behaviour and compulsive buying.
Results suggest a significant association between depression and impulse control disorders. One possibility is that a facet of impulsivity contributes to both problems, which could be important information for clinicians. Future studies will need to clarify the exact nature of the relationship between depression and impulse control disorders.
本研究旨在评估大学生样本中抑郁的影响，特别是与冲动控制障碍的关系。虽然先前的研究表明大学生中抑郁发生率很高，但迄今为止尚无研究评估抑郁水平是否与该人群中冲动控制障碍的发生率相关。
共有6000名学生参与了大学生计算机使用调查。共有1717名学生完成了本分析感兴趣的量表。参与者根据抑郁得分被分为几组：重度（N = 75）、轻度/中度（N = 647）和无抑郁（N = 995）。使用方差分析（ANOVA）或卡方检验对这三组进行评估。采用多项逻辑回归分析来阐明抑郁与冲动控制障碍诊断之间的关联。
三组在人口统计学、健康和学术变量方面存在差异。重度抑郁组报告的皮肤搔抓障碍、强迫性行为和强迫性购物发生率较高。
结果表明抑郁与冲动控制障碍之间存在显著关联。一种可能性是冲动性的一个方面导致了这两个问题，这可能是临床医生的重要信息。未来的研究需要阐明抑郁与冲动控制障碍之间关系的确切性质。
