To the Editor We would like to point out several limitations of the study by Christensen et al¹ comparing the effects of the individual placement and support (IPS) model of supported employment with IPS enhanced by cognitive remediation and social skills training (IPSE) and service as usual on work in persons with severe mental illness that preclude drawing firm conclusions about the potential benefits of augmenting IPS with cognitive remediation. Three sets of findings suggest problems implementing the IPS program.

可以从丹麦支持就业的随机临床试验中得出有限的结论。

致编辑我们想指出Christensen等人¹的研究存在的局限性，比较了个人安置和支持（IPS）的支持性就业与通过认知补救和社会技能培训（IPSE）和服务增强的IPS的效果照常在重度精神疾病患者中工作，因此无法就通过认知矫治提高IPS的潜在益处得出明确的结论。三组调查结果表明实施IPS计划存在问题。
