全世界有50万菲律宾女佣。然而，没有有效的工具来评估这一人群中常见的精神障碍。患者健康问卷（PHQ-9）和广泛性焦虑症（GAD-7）是简短的措施，可能是有效的筛选抑郁和焦虑的家庭佣工。本研究旨在建立菲律宾版PHQ-9和GAD-7的信度和效度。在研究1中，131名家政工人完成了PHQ-9，GAD-7和其他问卷，重测间隔为10天。收敛效度进行了检查，使用创伤后应激障碍，直接暴露于创伤事件，和反刍的措施。使用歧视，疼痛，社会支持和间接暴露于创伤事件的措施进行了评估的有效性。在研究2中，标准效度建立了另一个样本的家庭佣工（N = 100），使用临床医生管理的迷你国际神经精神访谈。采用受试者工作特征曲线（ROC）分析评价诊断效率。结果显示PHQ-9和GAD-7的内部一致性可接受且较高。两者都有可接受的重测信度。收敛和判别效度也建立。ROC曲线结果表明，PHQ-9和GAD-7的最佳切割分数分别为6和7。菲律宾语版的PHQ-9和GAD-7对菲律宾家庭佣工来说是可靠和有效的。
There are 500,000 female Filipino domestic workers worldwide. However, there are no validated instruments to assess common mental disorders in this population. The Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder (GAD-7) are brief measures that could be effective screeners for depression and anxiety in domestic workers. This study aims to establish reliability and validity of the Filipino versions of the PHQ-9 and GAD-7. In Study 1, 131 domestic workers completed the PHQ-9, GAD-7, and other questionnaires with a test-retest interval of 10 days. Convergent validity was examined using measures of posttraumatic stress disorder, direct exposure to traumatic events, and rumination. Discriminant validity was assessed using measures of discrimination, pain, social support, and indirect exposure to traumatic events. In Study 2, criterion validity was established with another sample of domestic workers (N = 100) using clinician-administered Mini International Neuropsychiatric Interviews. Receiver operating characteristic (ROC) curve analysis was performed to evaluate diagnostic efficiency. Results showed acceptable and high internal consistency for PHQ-9 and GAD-7, respectively. Both had acceptable test-retest reliability. Convergent and discriminant validity were also established. ROC curve results demonstrated that optimal cut scores for PHQ-9 and GAD-7 are 6 and 7, respectively. The Filipino versions of PHQ-9 and GAD-7 are reliable and valid for use among Filipino domestic workers.
