职业生活质量（ProQOL）量表是最广泛使用的同情满意度和疲劳的测量方法之一，尽管很少有公开的证据支持其有效性。本研究以310名儿童保护工作者为样本，采用验证性因子分析（CFA）和双因子模型评估了该措施的结构效度。CFA未能证实Stamm（2010）提出的三因素结构的充分性。为此，作者提出了一个双因素模型，该模型假设了一个包含一般因素和独立因素（同情满意度、工作倦怠和继发性创伤压力）的因素结构，突出了ProQOL的单维性，同时允许每个子量表单独使用。此外，该双因素模型与创伤后心理障碍量表存在中度相关（r = - 0.427, p < 0.001），与工作幸福感量表和工作心理困扰量表存在强相关（r = 0.694, p < 0.001），支持ProQOL的聚合效度。在ProQOL和生活事件清单之间没有发现关联，这支持ProQOL的区别效度。总体而言，研究结果表明，同情满意度和同情疲劳代表同一构念的较高水平和较低水平，而不是两个不同的构念。因此，研究人员和临床医生可以计算出一个单一的分数来评估专业人员的个人职业生活质量水平。
The Professional Quality of Life (ProQOL) scale is one of the most widely used measures of compassion satisfaction and fatigue despite there being little publicly available evidence to support its validity. This study, conducted among a sample of 310 child protection workers, assessed the construct validity of this measure using confirmatory factor analysis (CFA) and bifactor modeling. The CFA failed to confirm the adequacy of the three-factor structure proposed by Stamm (2010). In response, a bifactor model postulating a factor structure with a general factor in addition to independent factors (compassion satisfaction, job burnout, and secondary traumatic stress) was proposed, highlighting the unidimensionality of the ProQOL while allowing for each subscale to be used separately. Moreover, this bifactor model of the ProQOL was moderately correlated with the Posttraumatic Disorder Checklist, r = -.427, p < .001, and strongly correlated with scales of well-being at work, r = .694, p < .001, and psychological distress at work, r = -.666, p < .001, thus supporting the ProQOL's convergent validity. No associations were found between the ProQOL and the Life Event Checklist, which supports the ProQOL's discriminant validity. Overall, the results indicated that compassion satisfaction and compassion fatigue represent higher and lower levels of the same construct rather than two different constructs. Researchers and clinicians could therefore compute a single score to rate professionals' individual levels of professional quality of life.
