This study focused on assessing variables which may differentiate suicidal drug abusers from nonabusers. Data from a sample of drug abusing (n = 86) and nonabusing (n = 298) suicide attempters were subjected to a stepwise multiple regression analysis to identify factors related to suicidal intent. The analysis revealed that in our sample of suicide attempters, drug abuse status was not a significant contributor to the severity of suicidal intent. However, it was found that hopelessness accounted for a significant proportion of the variance of intent. The findings suggest that hopelessness among drug abusers, an important determinant of suicidal behavior, presents an important target for therapeutic intervention.
本研究着重评估可能区分自杀性药物滥用者与非药物滥用者的变量。来自药物滥用自杀未遂者样本（n = 86）和非药物滥用自杀未遂者样本（n = 298）的数据进行了逐步多元回归分析，以确定与自杀意图相关的因素。分析表明，在我们的自杀未遂者样本中，药物滥用状况并非自杀意图严重程度的显著影响因素。然而，发现绝望感在意图差异中占很大比例。研究结果表明，药物滥用者中的绝望感作为自杀行为的一个重要决定因素，是治疗干预的一个重要目标。
