Treatment of stimulant offenders in Japan is an urgent issue. One of the more recent support approaches for stimulant offenders in Japan is to understand and support them based on a self-medication hypothesis; however, the effect of trust on substance abuse severity among incarcerated stimulant offenders has not been examined. Additionally, while accounting for gender differences is essential when providing support for them, these differences have not also been examined.
To investigate gender differences in the effect of trust on substance abuse severity in a national sample of stimulant offenders in Japanese prisons.
Data from 586 incarcerated stimulant offenders who answered a nationwide questionnaire were analyzed. Descriptive statistics and multiple regression analyses were used to assess the association between trust and the severity of substance abuse.
Compared with men, women reported lower trust in others; moreover, their distrust in others and substance abuse severity were greater. After controlling for confounding factors, multiple regression analyses were conducted separately for men and women, with trust as the independent variable and substance abuse severity as the dependent variable. The models for both men (R = 0.180, p < 0.001) and women (R = 0.236, p < 0.001) were significant. Trust in oneself influenced drug dependence severity for men (β = -0.183, p < 0.01), whereas distrust in others influenced drug dependence severity for women (β = 0.185, p < 0.05).
These findings suggest that gender differences must be considered when supporting stimulant offenders in prison.
在日本，对兴奋剂犯罪者的治疗是一个紧迫的问题。日本最近针对兴奋剂犯罪者的一种支持方法是基于自我用药假说对他们进行理解和支持；然而，信任对被监禁的兴奋剂犯罪者药物滥用严重程度的影响尚未得到研究。此外，在为他们提供支持时考虑性别差异至关重要，但这些差异也未得到研究。
在日本监狱中全国范围的兴奋剂犯罪者样本中，调查信任对药物滥用严重程度影响的性别差异。
对586名回答了全国范围调查问卷的被监禁兴奋剂犯罪者的数据进行分析。使用描述性统计和多元回归分析来评估信任与药物滥用严重程度之间的关联。
与男性相比，女性报告对他人的信任较低；此外，她们对他人的不信任和药物滥用严重程度更高。在控制混杂因素后，分别对男性和女性进行多元回归分析，以信任作为自变量，药物滥用严重程度作为因变量。男性（R = 0.180，p < 0.001）和女性（R = 0.236，p < 0.001）的模型均具有显著性。对自己的信任影响男性的药物依赖严重程度（β = -0.183，p < 0.01），而对他人的不信任影响女性的药物依赖严重程度（β = 0.185，p < 0.05）。
这些发现表明，在支持监狱中的兴奋剂犯罪者时必须考虑性别差异。
