Most of the common models to examine depression are one-factor models; however, previous studies provided several-factor structure models on each depressive symptom using the Patient Health Questionnaire-9 (PHQ-9). The Nine-Questions Depression-Rating Scale (9Q) is an alternative assessment tool that was developed for assessing the severity of depressive symptoms in Thai adults. This study aimed to examine the factor structure of this tool based on the factor structure models for the PHQ-9 provided in previous studies using confirmatory factor analysis (CFA). We also examined the association of chronic diseases and depressive symptoms using the Multiple Indicators Multiple Causes model among 1346 participants aged 19 years old or more without psychiatric disorders. The results show that the two-factor CFA model with six items in the cognitive-affective domain and three items in the somatic domain provided the best fit for depressive symptoms in the study population (RMSEA = 0.077, CFI = 0.953, TLI = 0.936). Dyslipidemia was positively associated with both cognitive-affective symptoms ( = 0.120) and somatic depressive symptoms ( = 0.080). Allergies were associated with a higher level of cognitive-affective depressive symptoms ( = 0.087), while migraine ( = 0.114) and peptic ulcer disease ( = 0.062) were associated with a higher level of somatic symptoms. Increased age was associated with a lower level of somatic symptoms ( = -0.088). Our findings suggested that considering depressive symptoms as two dimensions yields a better fit for depressive symptoms. The co-occurrence of chronic diseases associated with depressive symptoms should be monitored.
大多数用于研究抑郁症的常见模型都是单因素模型；然而，先前的研究使用患者健康问卷-9（PHQ-9）为每种抑郁症状提供了多因素结构模型。九题抑郁评定量表（9Q）是一种替代评估工具，专为评估泰国成年人抑郁症状的严重程度而开发。本研究旨在使用验证性因素分析（CFA），基于先前研究中为PHQ-9提供的因素结构模型，检验该工具的因素结构。我们还使用多指标多原因模型，在1346名19岁及以上无精神疾病的参与者中，研究了慢性病与抑郁症状之间的关联。结果表明，认知情感领域有六个项目、躯体领域有三个项目的两因素CFA模型，对研究人群的抑郁症状拟合度最佳（RMSEA = 0.077，CFI = 0.953，TLI = 0.936）。血脂异常与认知情感症状（β = 0.120）和躯体抑郁症状（β = 0.080）均呈正相关。过敏与较高水平的认知情感抑郁症状相关（β = 0.087），而偏头痛（β = 0.114）和消化性溃疡疾病（β = 0.062）与较高水平的躯体症状相关。年龄增加与较低水平的躯体症状相关（β = -0.088）。我们的研究结果表明，将抑郁症状视为两个维度对抑郁症状的拟合度更好。应监测与抑郁症状相关的慢性病的共病情况。
