OBJECTIVE This work focuses on understanding quality of life and evaluating a brief quality of life measure in an outpatient emerging adult (17-25 years of age) substance use program. METHOD Mixed methods were used including: (a) psychometric evaluation of the adapted MyLifeTracker (MLT) based on assessments completed four times throughout treatment (n = 100) and (b) qualitative interviews with 12 emerging adults in the program. The study was codesigned, cofacilitated, and cointerpreted with emerging adults with lived experience. RESULTS At intake, emerging adults reported quality of life scores of 3.7/10 on average and significantly improved (change M = 2.1 points, d = 0.86, p < .001) at the ∼12-week follow-up demonstrating program effects and sensitivity to change. Factor analysis suggested unidimensionality of the measure and internal consistency was high (ω = 0.81). MLT scores correlated in expected directions with other measures of quality of life, functioning, and mental health symptoms and demonstrated incremental validity in explaining variability in these measures over and above World Health Organization quality of life items. Emerging adults thought the five items (i.e., general well-being, day-to-day activities, relationships with friends, relationships with family, coping) generally captured the most important aspects of quality of life to them and had positive impressions regarding the use of this measure for measurement-based care. Other important aspects of quality of life included feeling a sense of meaning, purpose, motivation, and independence. CONCLUSION Overall, the MLT demonstrated evidence of psychometric and content validity among emerging adults in substance use treatment. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

在物质使用计划中衡量和理解新兴成年人的“生活质量”。

目标 这项工作的重点是了解生活质量并评估门诊新兴成人（17-25 岁）物质使用计划的简要生活质量测量。方法 使用了混合方法，包括：(a) 基于在整个治疗过程中完成四次的评估 (n = 100) 对经过改编的 MyLifeTracker (MLT) 进行的心理测量评估，以及 (b) 对项目中 12 名新兴成年人的定性访谈。该研究由具有生活经验的新兴成年人共同设计、共同促进和共同解释。结果 在入学时，新兴成年人报告的平均生活质量得分为 3.7/10，并在 ~12 周的随访中显着改善（变化 M = 2.1 分，d = 0.86，p < .001），证明了计划的效果和敏感性改变。因素分析表明测量的单维性和内部一致性很高 (ω = 0.81)。MLT 分数在预期方向上与其他生活质量、功能和心理健康症状的衡量指标相关，并证明在解释这些衡量指标超过世界卫生组织生活质量项目的可变性方面具有递增的有效性。新兴成年人认为这五个项目（即总体幸福感、日常活动、与朋友的关系、与家人的关系、应对）通常涵盖了对他们来说生活质量最重要的方面，并且对使用这些项目有积极的印象这项措施用于基于测量的护理。生活质量的其他重要方面包括感觉意义、目的、动机和独立性。结论 总的来说，MLT 证明了新兴成年人在物质使用治疗中的心理测量和内容有效性的证据。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
