BACKGROUND
Outcome measures are routinely used in child and adolescent mental health services to demonstrate the effectiveness or otherwise of interventions.
METHODS
We followed up a consecutive sample from a large teaching hospital's Obsessive Compulsive Disorder (OCD) service for young people, comparing improvements using instruments of differing broadness.
RESULTS
The effect size of improvement decreased as the breadth of the questionnaire increased.
CONCLUSION
Specialist clinics are recommended to use two questionnaires: a broad one to facilitate comparability with other clinics, and a narrow one to maximise power to detect significant changes.
背景
在儿童和青少年心理健康服务中，结果测量被常规用于证明干预措施的有效性与否。
方法
我们对一家大型教学医院青少年强迫症（OCD）服务的连续样本进行了随访，使用不同广度的工具比较改善情况。
结果
随着问卷广度的增加，改善的效应量降低。
结论
建议专科医院使用两份问卷：一份广度较大的问卷以促进与其他科室的可比性，一份广度较小的问卷以最大限度地提高检测显著变化的能力。
