Individual Placement and Support (IPS), an evidence-based supported employment model for working-age adults with serious mental illness, also serves transition age adults (TAY; ages 16-24). The IPS-Y is a new IPS fidelity scale tailored to this younger population. Although adopted worldwide, it lacks research on the psychometric properties of its two components (employment and education). Six IPS programs serving TAY were assessed on IPS-Y (Employment) in an initial review (Time 1) and on both components in a second review one year later (Time 2). We examined scale calibration, reliability, and validity for the IPS-Y in this sample. Fidelity reviewers use the full range of ratings, from "not IPS" to "exemplary," on both IPS-Y components. On the employment component, item calibration was excellent; internal consistency reliability was good at Time 1 (r = .81) and test-retest reliability was fair (r = .63). The IPS-Y (Employment) showed excellent sensitivity to change, with the mean scale score increasing from 88.3 to 105.5. IPS-Y (Employment) item ratings at Time 2 were similar to corresponding items in a sample of conventional IPS programs using the standard IPS fidelity scale. Predictive validity was promising for both components, with fidelity scale ratings positively correlated with site-level competitive employment rates (r = .57) and education enrollment rates (r = .69). IPS can be implemented to good fidelity for programs serving TAY. Preliminary findings regarding the psychometric properties of the IPS-Y Employment are encouraging, but replication in larger samples is needed.
个体安置与支持（IPS）是一种针对患有严重精神疾病的适龄成年人的循证支持性就业模式，也适用于过渡年龄成年人（TAY；16 - 24岁）。IPS - Y是一种专门为这一年轻人群量身定制的新的IPS保真度量表。尽管该量表在全球范围内被采用，但其两个组成部分（就业和教育）的心理测量特性缺乏研究。在一项初步评估（时间1）中，对六个为TAY服务的IPS项目进行了IPS - Y（就业）评估，一年后的第二次评估（时间2）则对两个组成部分都进行了评估。我们在这个样本中检验了IPS - Y的量表校准、信度和效度。保真度评审员在IPS - Y的两个组成部分上使用从“非IPS”到“模范”的全部分级。在就业部分，项目校准非常出色；内部一致性信度在时间1时良好（r = 0.81），重测信度一般（r = 0.63）。IPS - Y（就业）对变化表现出极好的敏感性，平均量表得分从88.3提高到了105.5。时间2时IPS - Y（就业）项目评级与使用标准IPS保真度量表的传统IPS项目样本中的相应项目相似。两个组成部分的预测效度都很有前景，保真度量表评级与机构层面的竞争性就业率（r = 0.57）和教育入学率（r = 0.69）呈正相关。对于为TAY服务的项目，可以很好地实施IPS。关于IPS - Y就业部分心理测量特性的初步研究结果令人鼓舞，但需要在更大样本中进行重复验证。
