Studies have found Cannon-Spoor's Premorbid Adjustment Scale (PAS) to be a useful measure of premorbid function and an effective predictor of outcome in patients with chronic schizophrenia. Despite its widespread use, the applicability and reliability of the scale for use with young patients who experience their first episode of schizophrenia have not been thoroughly examined. We review the studies that used the PAS to assess premorbid function in patients with either chronic or first-episode schizophrenia. Difficulties that have been encountered with the use of the PAS in first-episode patients are presented, and modifications that have been made to the scale by various research groups are described. Finally, we make recommendations to enhance the use of the PAS when evaluating patients who have experienced their first episode of schizophrenia.
研究发现，坎农 - 斯普尔病前适应量表（PAS）是衡量病前功能的有效工具，也是慢性精神分裂症患者预后的有效预测指标。尽管该量表被广泛使用，但对于首次发作精神分裂症的年轻患者，其适用性和可靠性尚未得到充分检验。我们回顾了使用PAS评估慢性或首次发作精神分裂症患者病前功能的研究。介绍了在首次发作患者中使用PAS时遇到的困难，并描述了各研究小组对该量表所做的修改。最后，我们提出了一些建议，以加强PAS在评估首次发作精神分裂症患者时的应用。
