Can EPDS and EPDS-3A be used to replace GAD-7 to screen the anxiety of pregnant women during pregnancy examination?

OBJECTIVE

To examine the screening ability and cut-off scores of the Edinburgh Postnatal Depression Scale (EPDS) and EPDS-3A for pregnancy anxiety in pregnancy examination.

METHODS

This was a prospective repetitive measurement study. A follow-up survey was performed in Chinese pregnant women with the EPDS, the 7-item Generalized Anxiety Disorder (GAD-7) scale and a basic information questionnaire. A total of 609 women participated in all surveys at three trimesters, and all data were complete with no missing values. Receiver operating characteristic curves, Cohen's kappa and cross-tabulation were used to test the single and combined screening ability of EPDS and EPDS-3A for pregnancy anxiety.

RESULTS

The areas under the curves of EPDS and EPDS-3A were close to or more than 0.90. EPDS scores greater than 14 in the first trimester and greater than 13 in the second and third trimesters could be used as the cut-off values. EPDS-3A score greater than 4 could be used as the cut-off value in each trimester. Adding the EPDS-3A to the EPDS would lead to correct identification of an additional 6.33%, 6.35%, and 7.25% of anxious women and misdiagnosis of an additional 6.60%, 2.56%, and 2.41% of normal women in each trimester, respectively.

CONCLUSION

The EPDS and EPDS-3A can be used alone or in combination for initially screening of pregnancy anxiety. Under certain conditions, they can even be used to replace GAD-7 for anxiety screening to reduce the adverse influence of excessive screening on pregnant women, and improve the quality of survey data and efficiency of clinical services.

Can the Edinburgh Postnatal Depression Scale-3A be used to screen for anxiety?

Background

Anxiety in the ante- and postnatal period is prevalent, often co-occurs with depression, and can have adverse consequences for the infant. Therefore, perinatal mental health screening programs should not only focus on depression but also on detecting anxiety. However, in many already implemented perinatal screening programs, adding extra screening instruments is not feasible. We examine the utility of a subscale of the Edinburgh Postnatal Depression Scale (EPDS) consisting of items 3, 4, and 5 (EPDS-3A) for detecting anxiety in new mothers.

Methods

We used confirmatory factor analysis (CFA) to confirm the presence of the EPDS-3A found in a previous study (n = 320) where exploratory factor analysis (EFA) was used. For the CFA we used a sample of new mothers (n = 442) with children aged 2–11 months recruited from the same population from which mothers for the previous study was recruited. Three models were tested and compared. Receiver operating characteristics of the EPDS-3A were investigated in relation to anxiety caseness status on the combined sample (N = 762). Sample weighing was used to match the dataset to the target population. Cross tabulation was used to investigate the proportion of anxiety cases identified by the EPDS-3A above those identified with the total EPDS.

Results

The presence of the EPDS-3A was confirmed. An EFA-driven, two-dimensional 7-item model showed the best data fit with one factor representing the anxiety subscale consisting of items 3, 4, and 5. An EPDS-3A score of ≥ 5 was the most optimal for identifying cases of anxiety (sensitivity: 70.9; specificity: 92.2; AUC: 0.926). Further, we found that the EPDS-3A identifies an additional 2.5% of anxiety cases that would not have been identified with the total EPDS.

Conclusions

The EPDS-3A can be used as a time-efficient screening for possible anxiety in ante- and postnatal mothers. However, adding the EPDS-3A to routine screening with the total EPDS does not lead to a substantial increase in the number of women identified. In line with previous studies, this study confirms that the EPDS identifies anxiety in addition to depression. Therefore, assessment and treatment adjusted to the specific emotional difficulties is imperative.

Generalized and pregnancy-related anxiety prevalence and predictors among pregnant women attending primary health care in Qatar, 2018-2019

Background

Cumulative evidence suggests that early identification of anxiety in pregnancy is important, given that antenatal anxiety has been linked to morbid outcomes in expecting mothers and their offspring. However, the burden of antenatal anxiety is not yet known in Qatar. This research aims to measure the prevalence and determinants of generalized and pregnancy-related anxiety among pregnant women.

Methods

Eight hundred pregnant women completed a structured interview and self-administrated questionnaires after being selected through probability sampling from nine primary healthcare centers distributed across Qatar. We subjected the data to Binary and Multiple Logistic Regression Analysis. Furthermore, we conducted a Confirmatory Factor Analysis for the utilized scales.

Results

Out of eight hundred participants, 26.5% reported high pregnancy-related anxiety, while 16.4% had a generalized anxiety disorder. A high level of perceived social support and resilience was shown to mitigate generalized and pregnancy-related anxiety. However, we revealed that different determinants influence the two types of anxiety.

Limitations

There is no recognized optimal cut-off point to distinguish ‘high risk’ in pregnancy-related anxiety scales.

Conclusions

Pregnancy-related anxiety is more prevalent than generalized anxiety among pregnant women in Qatar, indicating that stakeholders must include screening for pregnancy-related anxiety in Qatar's clinical guidelines. Tailored interventional studies could focus on increasing resilience and social support to decrease the burden of antenatal anxiety.
