重度抑郁症（MDD）和广泛性焦虑症（GAD）是高度流行的共病性疾病，具有显著的症状重叠，在准确区分和诊断这些疾病方面提出了挑战。三方模型认为，焦虑唤醒是特定于焦虑和快感缺乏是特定于抑郁，虽然焦虑恐惧可能发挥更大的作用比焦虑唤醒广泛性焦虑障碍。本研究使用二进制支持向量机学习算法在成人样本（n = 150）中测试了情绪和焦虑症状问卷调查表（MASQ-AD）和焦虑唤醒（MASQ-AA）量表以及宾夕法尼亚州立大学焦虑问卷（PSWQ）在识别终身或当前MDD、当前重度抑郁发作（MDE）和GAD方面的有效性。PSWQ和MASQ-AD分别在GAD和当前MDE的筛查和识别中表现出预测效用，MASQ-AD 8项子量表优于MASQ-AD 14项子量表。MASQ-AA不能预测MDD、当前MDE或GAD，MASQ-AD不能预测当前或终生MDD。PSWQ和MASQ-AD是GAD和当前MDE的有效和准确的筛查工具。结果支持三方模型，快感缺乏是抑郁症所特有的，但包括焦虑的忧虑作为一个单独的维度焦虑是必要的。
Major depressive disorder (MDD) and generalized anxiety disorder (GAD) are highly prevalent, co-occurring disorders with significant symptom overlap, posing challenges in accurately distinguishing and diagnosing these disorders. The tripartite model proposes that anxious arousal is specific to anxiety and anhedonia is specific to depression, though anxious apprehension may play a greater role in GAD than anxious arousal. The present study tested the efficacy of the Mood and Anxiety Symptom Questionnaire anhedonic depression (MASQ-AD) and anxious arousal (MASQ-AA) scales and the Penn State Worry Questionnaire (PSWQ) in identifying lifetime or current MDD, current major depressive episode (MDE), and GAD using binary support vector machine learning algorithms in an adult sample (n = 150). The PSWQ and MASQ-AD demonstrated predictive utility in screening for and identification of GAD and current MDE respectively, with the MASQ-AD eight-item subscale outperforming the MASQ-AD 14-item subscale. The MASQ-AA did not predict MDD, current MDE, or GAD, and the MASQ-AD did not predict current or lifetime MDD. The PSWQ and MASQ-AD are efficient and accurate screening tools for GAD and current MDE. Results support the tripartite model in that anhedonia is unique to depression, but inclusion of anxious apprehension as a separate dimension of anxiety is warranted.
