The present study explored predictors of the duration of therapy exclusive of outcome utilizing data on 77 patients at St. John's University Center for Psychological Services. Measures of time in therapy were the total number of sessions attended and the number of sessions attended within the first six months of therapy. A bivariate Pearson product-moment correlation matrix was constructed, comprised of measures for time in therapy, severity of symptom measures, treatment modality (psychodynamic or cognitive-behavioral), age, and sex. There was a significant correlation between scores on state anxiety and the total number of sessions as well as between scores on state anxiety and number of sessions attended within six months, but no other correlations between measures of severity of symptoms and time in therapy were significant (p > .05). The results indicate that severity of symptoms does not significantly predict the duration of therapy.
本研究利用圣约翰大学心理服务中心77名患者的数据，探讨了排除治疗结果因素后治疗时长的预测因素。治疗时间的衡量指标为参加的总疗程数以及治疗前六个月内参加的疗程数。构建了一个双变量皮尔逊积差相关矩阵，该矩阵由治疗时间、症状严重程度指标、治疗方式（心理动力学或认知行为疗法）、年龄和性别等指标组成。状态焦虑得分与总疗程数之间以及状态焦虑得分与六个月内参加的疗程数之间存在显著相关性，但症状严重程度指标与治疗时间之间的其他相关性均不显著（p>0.05）。结果表明，症状严重程度并不能显著预测治疗时长。
