This study used ecological momentary assessment (EMA) to measure positive affect (PA) and negative affect (NA) among people who inject drugs (PWID) and examined associations with borderline personality disorder (BPD) symptoms and difficulties with emotion regulation, in the context of injection drug use. We recruited PWID, ages 18-35 years, through syringe exchange program sites in Chicago, Illinois. After completing a baseline interview including a screener for BPD and the Difficulties in Emotion Regulation Scale (DERS), participants used a mobile phone app to report mood, substance use, and injection behavior for 2 weeks. Participants who completed at least 2 EMA assessments were included in the analysis (N = 161). The mean age was 30, about 1/3 were women, 63% were non-Hispanic White, and 23% were Hispanic. In multivariable mixed-effects regression models, positive BPD screen was associated with greater momentary NA intensity and greater instability of both NA and PA. Independent of BPD screening status, DERS score was associated positively with momentary NA intensity and instability and negatively with PA intensity. This finding suggests that emotion dysregulation is an appropriate target for assessment and intervention. Whereas concurrent withdrawal was associated with both greater NA and less PA, opioid intoxication was associated with only greater PA. We did not find support for our hypothesis that emotion dysregulation would moderate the effect of withdrawal on NA. Findings support the validity of the EMA mood measure and the utility of studying mood and behavior among PWID using EMA on mobile phones.

注射吸毒者的负面影响和情绪失调:一项生态瞬时评估研究。

本研究使用生态瞬时评估 (EMA) 来衡量注射吸毒者 (PWID) 的积极影响 (PA) 和消极影响 (NA),并在上下文中检查与边缘型人格障碍 (BPD) 症状和情绪调节困难的关联注射毒品的使用。我们通过伊利诺伊州芝加哥的注射器交换项目站点招募了年龄在 18-35 岁之间的 PWID。在完成包括 BPD 筛查器和情绪调节困难量表 (DERS) 的基线访谈后,参与者使用手机应用程序报告情绪、药物使用和注射行为 2 周。完成至少 2 项 EMA 评估的参与者被纳入分析(N = 161)。平均年龄为 30 岁,约 1/3 为女性,63% 为非西班牙裔白人,23% 为西班牙裔。在多变量混合效应回归模型中,阳性 BPD 筛查与更大的瞬时 NA 强度和更大的 NA 和 PA 不稳定性相关。独立于 BPD 筛查状态,DERS 评分与瞬时 NA 强度和不稳定性呈正相关,与 PA 强度呈负相关。这一发现表明情绪失调是评估和干预的合适目标。虽然同时戒断与更大的 NA 和更少的 PA 相关,但阿片类药物中毒仅与更大的 PA 相关。我们没有发现支持我们的假设,即情绪失调会减轻戒断对 NA 的影响。调查结果支持 EMA 情绪测量的有效性以及在手机上使用 EMA 研究 PWID 中情绪和行为的效用。(PsycInfo 数据库记录 (c) 2020 APA,
