Women with a history of substance use disorder (SUD) constitute a unique population with gender-specific needs in treatment. Most notable is high rates of prior trauma and the need for a trauma-informed care framework. Given theoretical links between trauma and interpersonal trust, understanding quantitatively how trust may impact outcomes for women in this population requires confirmation of validity of existing psychometric instruments. This study sought to confirm reliability and construct validity of the Rotter Interpersonal Trust Scale, Wake Forest Trust in Physician Scale, and the Revised Health Care System Distrust Scale (RHCSDS) for use in women with a history of SUD seeking treatment in a community-based setting. A total of 301 participants were enrolled between August 2017 and March 2018 at an urban, community-based residential substance abuse treatment program in the mid-South. Participants were given an electronic survey containing questions about demographics/clinical characteristics, the Rotter, Wake Forest, and RHCSDS scales, Socially Desirable Response Five-Item Survey (SDRS-5), and the Adverse Childhood Experiences (ACEs) questionnaire. All participants also completed a modified protocol of the "Trust Game." Statistical analysis was completed for each trust scale in regard to scale means and distribution, internal consistency, interscale correlation, and scale correlation to the ACE score. Results confirm statistically significant ( < .001) differences in global trust and trust of health care providers compared with general population samples in prior studies. Internal consistency of scales is comparable to reliability testing in prior studies (α > .70 for all scales). Interscale correlation between individual scales is statistically significant, with the strongest relationship between the 2 health care-specific scales ( = -.740, < .001). There was a weak, negative correlation between the ACE score and interpersonal trust ( = -.135, = .019). Individual scales do not have statistically significant correlation with "Trust Game" scores. Findings suggest reliability and construct validity of scales for use in this population.
有物质使用障碍（SUD）病史的女性是一个独特的群体，在治疗方面有特定的性别需求。最显著的是既往创伤发生率高，以及需要一个创伤知情护理框架。鉴于创伤与人际信任之间的理论联系，定量了解信任如何影响该群体中女性的治疗结果，需要确认现有心理测量工具的有效性。本研究旨在确认Rotter人际信任量表、维克森林医生信任量表和修订后的医疗保健系统不信任量表（RHCSDS）在有SUD病史且在社区环境中寻求治疗的女性中的可靠性和结构效度。2017年8月至2018年3月期间，共有301名参与者在中南部一个城市的社区居住性药物滥用治疗项目中登记。参与者接受了一项电子调查，其中包含有关人口统计学/临床特征、Rotter量表、维克森林量表和RHCSDS量表、社会期望反应五项调查（SDRS - 5）以及童年不良经历（ACEs）问卷的问题。所有参与者还完成了“信任游戏”的修改版协议。针对每个信任量表，就量表均值和分布、内部一致性、量表间相关性以及量表与ACE评分的相关性进行了统计分析。结果证实，与先前研究中的一般人群样本相比，在总体信任和对医疗保健提供者的信任方面存在统计学显著差异（<0.001）。量表的内部一致性与先前研究中的可靠性测试相当（所有量表的α>0.70）。各个量表之间的量表间相关性具有统计学意义，其中两个特定于医疗保健的量表之间的关系最强（=-0.740，<0.001）。ACE评分与人际信任之间存在微弱的负相关（=-0.135，=0.019）。各个量表与“信任游戏”得分没有统计学显著相关性。研究结果表明这些量表在该群体中的可靠性和结构效度。
