Abstract：
UNASSIGNED: Depression in adolescence is a serious major global health problem with increasing rates of prevalence. Measures of depression that are valid for young people are clearly needed in clinical contexts.
UNASSIGNED: The study included 577 patients from child and adolescent psychiatry (n = 471) and primary care (n = 106) aged 12-22 years in Sweden (Mage=16.7 years; 76% female). The reliability and validity for Montgomery-Åsberg Depression Rating Scale - Youth (MADRS-Y) were investigated. To confirm the latent structure, we used a single-factor confirmatory factor analysis (CFA). A Kruskal-Wallis test was performed to test total score differences between diagnostic groups. Using Spearman\'s rho correlations, we examine whether single items in the MADRS-Y correlate with suicidal ideation measured by The Suicidal Ideation Questionnaire-JR (SIQ-JR).
UNASSIGNED: The internal consistency using McDonald\'s coefficient omega was excellent. The CFA of the 12-item MADRS-Y supported a one factor structure. Evidence of convergent and discriminant validity was shown. There was a significant difference in MADRS-Y scores across diagnostic groups, with higher results for depressive disorders. A strong correlation with suicidal ideation was found for two items.
UNASSIGNED: The results support MADRS-Y as a brief, reliable, and valid self-report questionnaire of depressive symptoms for young patients in a clinical setting.

摘要：
青少年抑郁症是一个严重的全球健康问题，患病率不断上升。在临床环境中，显然需要对年轻人有效的抑郁症措施。
■该研究包括577名来自瑞典12-22岁的儿童和青少年精神病学（n=471）和初级保健（n=106）的患者（Mage=16.7岁；76％为女性）。调查了蒙哥马利-奥斯贝格抑郁量表-青年（MADRS-Y）的信度和效度。为了确认潜在的结构，我们使用单因素验证性因素分析(CFA)。进行Kruskal-Wallis测试以测试诊断组之间的总评分差异。使用斯皮尔曼的rho相关性，我们检查了MADRS-Y中的单个项目是否与自杀意念问卷JR（SIQ-JR）测量的自杀意念相关。
■使用麦当劳系数omega的内部一致性非常好。12项MADRS-Y的CFA支持单因素结构。显示了收敛效度和判别效度的证据。诊断组之间的MADRS-Y评分存在显着差异，对抑郁症有更高的结果。发现两个项目与自杀意念有很强的相关性。
■结果支持MADRS-Y，可靠,和有效的抑郁症状自我报告问卷的年轻患者在临床环境中。
