A large proportion of young people accessing specialist mental health services do so for a single session. The aim of the present study was to examine the characteristics of young people attending specialist mental health services for a single session and to examine associations between single session attendance and clinical characteristics. Secondary analysis of administrative data on N = 23,300 young people (mean age = 12.73 years, 57% female, 64% White British) was conducted. The mean number of sessions attended was 4.33 and 46% (10,669) attended for a single session. Multilevel logistic regression analysis showed that younger children, Black young people (OR = 1.20, 95% CI = 1.01–1.43) or those whose ethnicity was not stated (OR = 1.25, 95% CI = 1.15–1.35), young people with peer relationship difficulties (OR = 1.11, 95% CI = 1.04–1.19) or low frequency problems (OR = 1.06, 95% CI = 0.99–1.14), and those with more complexity factors (OR = 1.07, 95% CI = 1.04–1.10) were more likely to attend services for a single session. The present study sets out research questions to prompt future research: (1) the experience of attending services for a single session, (2) identifying groups of single session attenders who do not require further support compared to those who are not able to sustain engagement with more sessions, and (3) whether new care pathways are needed for these groups who currently access specialist mental health services for a single session.

大部分获得专业心理健康服务的年轻人都是在一次会议上这样做的。本研究的目的是检查参加单次专科心理健康服务的年轻人的特征，并检查单次就诊与临床特征之间的关联。N的行政数据二次分析 = 23,300 名年轻人（平均年龄 = 12.73 岁，57% 为女性，64% 为英国白人）。参加的平均会议次数为 4.33，单次参加的人数为 46% (10,669)。多级逻辑回归分析显示，年龄较小的儿童、黑人年轻人（OR = 1.20，95% CI = 1.01–1.43）或未说明种族的人（OR = 1.25，95% CI = 1.15–1.35）、有同龄人的年轻人关系困难（OR = 1.11, 95% CI = 1.04–1.19）或低频问题（OR = 1.06, 95% CI = 0.99–1.14），以及具有更多复杂因素的问题（OR = 1.07, 95% CI = 1.04– 1.10) 更有可能参加单次服务。本研究提出了一些研究问题以促进未来的研究：（1）参加单次服务的经验，
