Purpose: The Theory Evaluation Scale (TES) is a psychometric tool for analyzing theoretical frameworks that guide practice. Its flexibility assumption contends that a single rater or a panel of experts can evaluate a given theory and the two sets of scores will be comparable. This study tests this assumption, using a popular practice model in social work: the Strengths Perspective (SP). Method: A panel of 50 social work faculty and administrators from five English-speaking countries used the TES to determine the theoretical quality of the SP. Their scores were first analyzed through common measures of central tendency and then compared to findings in an existing evaluation for the same theory. Results: The analysis yielded excellent overall TES scores for the SP (mean = 32.03, median = 33.00, mode = 36). These results reflect the 35 overall score that the theory received in Joseph et al.'s (2022) evaluation. Conclusion: Therefore, besides showing an excellent overall quality for the SP, these results support the flexibility assumption of the TES. These findings bear major implications for social work theory, practice, and research.

优势视角与理论评价量表的比较分析

目的：理论评估量表（TES）是一种心理测量工具，用于分析指导实践的理论框架。其灵活性假设认为，单个评估者或专家小组可以评估给定的理论，并且两组分数将具有可比性。本研究使用社会工作中流行的实践模型：优势视角（SP）来检验这一假设。方法：由来自五个英语国家的 50 名社会工作教师和管理人员组成的小组使用 TES 来确定 SP 的理论质量。首先通过常见的集中趋势指标对他们的分数进行分析，然后与同一理论的现有评估结果进行比较。结果：分析得出 SP 的总体 TES 得分优异（平均值 = 32.03，中位数 = 33.00，众数 = 36）。这些结果反映了该理论在 Joseph 等人 (2022) 的评估中获得的 35 分总分。结论：因此，除了显示 SP 具有出色的整体质量外，这些结果还支持 TES 的灵活性假设。这些发现对社会工作理论、实践和研究具有重大意义。
