This study describes the development and tests the validity of the Problem Resolution Scale (PRS)—a single-item measure developed by researchers at Systemic Practice Research Network (SYPRENE) for assessing the degree to which the focal problem of therapy is perceived as resolved. Data were collected at termination from 747 clients seen across 18 therapists. Results suggested good construct validity, supported by a strong correlation between client and therapist perceptions as assessed by the PRS (r = 0.71, p < 0.001). Good criterion validity was also supported by strong correlations between client-reported psychological well-being and functioning at termination and both client-reported (r = −0.63; p < 0.001) and therapist-reported (r = −0.66; p < 0.001) problem resolution scores. Linear mixed model regression and stratified correlation analysis controlling for the therapist and presenting problem effects confirmed criterion validity. Results provide initial evidence for the validity and utility of the PRS.

问题解决量表：用于轻松评估临床改善的单项工具

本研究描述了问题解决量表 (PRS) 的开发并测试其有效性，该量表是由系统实践研究网络 (SYPRENE) 的研究人员开发的单项测量方法，用于评估治疗焦点问题被视为解决的程度。数据是在终止时从 18 名治疗师所见的 747 名客户中收集的。结果表明良好的结构效度，并得到 PRS 评估的来访者和治疗师看法之间的强相关性的支持（r  = 0.71，p  < 0.001）。良好的标准有效性还得到了客户报告的心理健康状况和终止时功能之间以及客户报告（r  = -0.63；p  < 0.001）和治疗师报告（r  = -0.66；p  < 0.001）之间的强烈相关性的支持。问题解决分数。线性混合模型回归和分层相关分析控制治疗师并呈现问题效果证实了标准的有效性。结果为 PRS 的有效性和实用性提供了初步证据。
