This systematic review and meta-analysis evaluated the effectiveness of cognitive behavioural therapy (CBT) interventions on stress outcomes in 6966 pregnant women across 20 randomized controlled trials. The results indicated significant reductions in pregnancy-specific stress symptoms (Hedges' g = -0.84) and generic stress symptoms (g = -0.64) post-intervention, although no significant effect on cortisol levels was observed.
Key findings
- CBT interventions significantly reduced pregnancy-specific stress symptoms with Hedges' g = -0.84.
- Generic stress symptoms were reduced with a Hedges' g = -0.64.
- No significant effect on cortisol levels was found (g = -0.99, p = .12).
- Younger age and lower attrition rates improved intervention effectiveness.
Why it matters
Given the prevalence of stress during pregnancy, effective interventions like CBT can enhance antenatal care, potentially improving maternal and fetal outcomes. Understanding the factors influencing intervention effectiveness can guide future practices.
What to keep in mind
The overall certainty of the evidence was rated as very low or low, and substantial heterogeneity was noted among studies.
