Comparing the effectiveness of virtual and semi-attendance Stress Inoculation Training [SIT] techniques in improving the symptoms of anxiety, depression, and stress of pregnant women with psychological distress: a multicenter randomized controlled trial.

BACKGROUND: Some studies indicate that more than 10% of pregnant women are affected by psychological problems. The current COVID-19 pandemic has increased mental health problems in more than half of pregnant women. The present study compared the effectiveness of virtual (VSIT) and semi-attendance Stress Inoculation Training (SIT) techniques on the improvement of the symptoms of anxiety, depression, and stress of pregnant women with psychological distress. METHODS: This study was conducted on 96 pregnant women with psychological distress in a 2-arm parallel-group, randomized control trial between November 2020 and January 2022. The semi-attendance SIT received treatment for six sessions, sessions 1, 3 and 5 as individual face-to-face and sessions 2, 4 and 6 as virtual once a week for 60 min continuously [n = 48], and the virtual SIT received six sessions simultaneously once a week for 60 min (n = 48) in pregnant women of 14-32 weeks' gestation referred to two selected hospitals. The primary outcome of this study was BSI-18 [Brief Symptom Inventory] and NuPDQ-17 [Prenatal Distress Questionnaire]. The secondary outcomes were the PSS-14 [Cohen's General Perceived Stress Scale]. Both groups completed questionnaires measuring anxiety, depression, pregnancy-specific stress, and generally perceived stress questionnaires before and after the treatment. RESULTS: The post-intervention results showed that the stress inoculation training technique in both VSIT and SIT interventions effectively reduced anxiety, depression, psychological distress, pregnancy-specific stress and general perceived stress [P < 0.01]. Also, the SIT interventions on decreasing anxiety [P < 0.001, η2 = 0.40], depression [P < 0.001, η2 = 0.52] and psychological distress [P < 0.001, η2 = 0.41] were more considerable than that of VSIT. However, There was no significant difference between SIT and VSIT intervention in terms of their effects on pregnancy-specific stress [P < 0.38, η2 = 0.01] and general stress [P < 0.42, η2 = 0.008]. CONCLUSION: The semi-attendance SIT group has been a more effective and practical model than the VSIT group, for reducing psychological distress. Therefore, semi-attendance SIT is recommended for pregnant women.
