Patient cooperation is recognized as an important factor in the outcome of orthodontic treatment. In order to predict patient cooperation, there have been numerous studies which have examined its correlates in orthodontic treatment. However, few, if any, of these studies have considered the reliability or stability of their patient cooperation measures. Hence, the correlates found or not found are suspect. The present article reports on the internal consistency and stability of the Orthodontic Patient Cooperation Scale (OPCS). Using the responses of practicing orthodontists, a list was generated of ten patient behaviors frequently considered in evaluating a patient's cooperation. Subjects were eighth- and ninth-grade students undergoing orthodontic treatment, who were rated by their own orthodontists after 2 months and 6 months of treatment. The internal consistency for the scale was estimated to be 0.71 (N = 44) at 2 months and 0.80 (N = 45) at 6 months. The correlation between scores at 2 months and at 6 months was 0.58 (N = 44), which may be considered to be a conservative estimate of the long-term stability of the scale. In summary, the OPCS has adequate internal consistency and reasonably stable scores over a 4-month period. As such, it should prove useful in studies looking for predictors of patient cooperation and in studies examining the relationship of patient cooperation and outcome of treatment.
患者的配合被认为是正畸治疗结果的一个重要因素。为了预测患者的配合情况，已有大量研究探讨了其在正畸治疗中的相关因素。然而，这些研究中几乎没有（如果有的话）考虑过其患者配合度测量方法的可靠性或稳定性。因此，所发现或未发现的相关因素都值得怀疑。本文报告了正畸患者配合度量表（OPCS）的内部一致性和稳定性。利用正畸医生的反馈，生成了一份在评估患者配合度时经常考虑的十种患者行为清单。研究对象是接受正畸治疗的八年级和九年级学生，在治疗2个月和6个月后由他们自己的正畸医生进行评分。该量表的内部一致性在2个月时估计为0.71（N = 44），在6个月时为0.80（N = 45）。2个月时和6个月时的分数之间的相关性为0.58（N = 44），这可以被认为是该量表长期稳定性的保守估计。总之，OPCS具有足够的内部一致性，并且在4个月的时间内分数相当稳定。因此，它在寻找患者配合度预测因素的研究以及研究患者配合度与治疗结果关系的研究中应该会被证明是有用的。
