Is It Useful to Screen for Anxiety using the GAD-7 in Pregnant Women?

Research Paper Title

Validation of the Generalised Anxiety Disorder Screener (GAD-7) in Spanish Pregnant Women.

Background

Anxiety during pregnancy is one of the most common mental health problems and a significant risk factor for postpartum depression. The Generalised Anxiety Disorder-7 (GAD-7) is one of the most widely used self-report measures of anxiety symptoms available in multiple languages. This study evaluates the psychometric properties and underlying factor structures of the Spanish GAD-7 among pregnant women in Spain.

Methods

Spanish-speaking pregnant women (N = 385) were recruited from an urban obstetrics setting in Northern Spain. Women completed the GAD-7 and the anxiety subscale of the Symptom Checklist (SCL90-R) at three time points, once per trimester. The reliability, concurrent validity, and factor analyses were conducted to evaluate the psychometric properties and factor structure, respectively.

Results

In the first trimester, the GAD-7 demonstrated good internal consistency (a = 0.89). GAD-7 is positively correlated with SCL90-R (anxiety subscale; r=0.75; p < 0.001). The proposed one-factor structure is found using exploratory factor analysis -FACTOR programme – with Unweighted Least Squares procedure and optimal implementation of parallel analysis (GFI = 0.99).

Conclusions

Health providers should screen for anxiety using the GAD-7 during pregnancy among urban Spanish-speaking samples to provide appropriate follow-up care.
