Abstract
BACKGROUND

The perinatal period is a challenging time of substantial emotional, physiological, social, and relational changes. Depression, anxiety, and stress symptoms are common, and co-exist in the perinatal period. Digital technology continues to grow at an unprecedented pace with wide application, including psychotherapeutic intervention. A growing number of meta-analyses supported the application of digital psychotherapeutic intervention across different populations, but relatively few meta- and meta-regression analyses have concentrated on perinatal women.

AIM

To evaluate the effectiveness of digital psychotherapeutic intervention on improving psychological outcomes among perinatal women and identify its essential features.

METHODS

Randomized controlled trials (RCTs) were obtained from eight databases, including Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Embase, Scopus, PsycINFO, PubMed, Web of Science, and ProQuest Dissertation and Theses from inception up until November 24, 2020. Comprehensive Meta-analysis 3.0 software was used to conduct meta- and meta-regression analyses. The Cochrane risk-of-bias tool and the Grading of the Recommendation, Assessment, Development, and Evaluation system were adopted to assess the individual and overall qualities of the evidence, respectively.

RESULTS

A total of 25 RCTs that included 3239 women were identified. Meta-analyses revealed that intervention significantly improved depression (Hedges’s g = 0.49), anxiety (g = 0.25), and stress (g = 0.47) symptoms compared to the control. Subgroup analyses demonstrated that a website platform with ≥ eight therapist-guided sessions using the theoretical principle of cognitive behavioral therapy was more effective than other treatments in improving depression symptoms in postnatal women. Meta-regression analyses observed that the age of perinatal women and the type of psychotherapy also had statistically significant effects on depression symptoms. Egger’s regression asymmetry tests suggested that no publication biases occurred, but the overall quality of the evidence was very low.

CONCLUSION

This review suggests that digital psychotherapeutic intervention may be a potential solution to reduce psychological problems in perinatal women. Further high-quality RCTs with large sample sizes are needed.

Core Tip: This systematic review identified and analyzed the findings of 25 randomized controlled trials, and the results indicated that digital psychotherapeutic intervention could significantly reduce depression, anxiety, and stress symptoms among perinatal women. The essential features of this intervention were a website platform with ≥ eight therapist-guided sessions using the cognitive behavioral therapy theoretical principle. This intervention was also effective in reducing depression symptoms when treating young postnatal women. The overall evidence grade of outcomes was very low according to the Grading of Recommendations, Assessment, Development, and Evaluation criteria. Thus, future trials need to include a high-quality design and a large sample size.
