Abstract

Background: The use of online questionnaires to assess common mental disorders such as perinatal anxiety has spread due to the proliferation of Internet-based psychological interventions and research. This study analyses the validity and reliability of the online version of the Generalized Anxiety Disorder-7 (GAD-7) in a sample of pregnant and postpartum Spanish women.

Method: A total of 3082 pregnant (n = 1260) and postpartum (n = 1822) women were recruited via the Internet and underwent three follow-up evaluations during a six-month period.

Results: A one-factor solution was assigned by Exploratory Factor Analysis and confirmed by Confirmatory Factor Analysis for both pregnant (CFI = 0.998; RMSEA = 0.035) and postpartum (CFI = 0.998; RMSEA = 0.038) women. The one-factor model showed strict invariance across groups. Validity was confirmed by assessing correlations between GAD-7, the Edinburgh Postnatal Depression Scale, and the 10-item Posttraumatic Stress Disorder checklist at three time points. The reliability coefficient was .92 for the two groups.

Conclusions: This study shows that the Spanish online GAD-7 version has good psychometric properties and can be used to assess anxiety symptoms during the perinatal period.

在线版一般焦虑症-7（GAD-7）的心理计量特性：西班牙孕妇和产后妇女纵向研究》。

背景：随着基于互联网的心理干预和研究的普及，使用在线问卷来评估围产期焦虑症等常见精神障碍的做法已经得到推广。本研究分析了在线版广泛焦虑症-7（GAD-7）在西班牙孕妇和产后妇女样本中的有效性和可靠性：方法：通过互联网共招募了 3082 名孕妇（= 1260 人）和产后妇女（= 1822 人），并在 6 个月内进行了三次随访评估：对孕妇（CFI = 0.998；RMSEA = 0.035）和产后妇女（CFI = 0.998；RMSEA = 0.038）的探索性因子分析得出了单因子解，确认性因子分析也证实了这一点。单因素模型在各组间显示出严格的不变性。通过评估 GAD-7、爱丁堡产后抑郁量表和 10 项创伤后应激障碍检查表在三个时间点的相关性，证实了该模型的有效性。两组的可靠性系数为 0.92：本研究表明，西班牙文在线版 GAD-7 具有良好的心理测量特性，可用于评估围产期焦虑症状。
