Validation of the Generalised Anxiety Disorder Screener (GAD-7) in Spanish Pregnant Women.
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.
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.
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).
Health providers should screen for anxiety using the GAD-7 during pregnancy among urban Spanish-speaking samples to provide appropriate follow-up care.
