Non-specialist-delivered psychosocial intervention for prenatal anxiety in a tertiary care setting in Pakistan: a qualitative process evaluation

Multiple mediation analysis of a task-shared psychosocial intervention for perinatal anxiety: Exploratory findings from a randomized controlled trial in Pakistan

BACKGROUND

The "Healthy Mother Healthy Baby" (HMHB) study is a phase three, single-blind randomized clinical trial conducted at Holy Family Hospital (HFH) in association with Rawalpindi Medical University (RMU). We aimed to examine the mediators of a specialized psychosocial approach based on Cognitive Behavioural Therapy principles, targeting pregnant women experiencing anxiety. The HMHB intervention was effective in treating perinatal anxiety symptoms and preventing future depressive episodes.

METHODS

The trial randomized participants into two arms: the HMHB intervention or Enhanced Usual Care (EUC), following World Health Organization guidelines. The HMHB intervention comprised strategies to strengthen social support networks, improving mother-baby bonding and strategies to deal with interpersonal conflicts, economic challenges, and societal gender preferences using cognitive and behavioural techniques and culturally resonant illustrations. Participants underwent rigorous data collection at three pivotal timepoints: baseline, third trimester, and 6-weeks postnatal. The primary outcome was anxiety symptom severity scores using the Hospital Anxiety and Depression Scale (HADS) at 6-weeks post-childbirth. Four potential mediators - social support, behavioural activation, perceived stress, and pregnancy experience - were assessed in the third trimester of pregnancy.

RESULTS

A total of 1200 participants were randomized to the HMHB and EUC arms. In the six-week follow-up time point, 379 participants remained in the EUC group, and 387 continued in the HMHB group. Post-intervention, HMHB participants displayed significant improvements in postnatal anxiety and depression scores. Mediation analyses revealed social support and pregnancy hassles as significant mediators of the intervention's effect on postnatal anxiety outcomes, while only social support emerged as a significant mediator for depression outcomes.

CONCLUSION

The HMHB intervention showed promising results in improving anxiety and depression scores among pregnant women. Significant mediation effects suggest the importance of targeting social support and managing pregnancy-related hassles for optimal intervention effectiveness.

Impact of an intervention for perinatal anxiety on breastfeeding: findings from the Happy Mother-Healthy Baby randomized controlled trial in Pakistan

BACKGROUND

The study examined the effects of Happy Mother-Healthy Baby (HMHB), a cognitive-behavioural therapy (CBT) intervention on breastfeeding outcomes for Pakistani women with prenatal anxiety.

METHODS

Breastfeeding practices were evaluated in a randomized controlled trial between 2019 and 2022 in a public hospital in Pakistan. The intervention group was randomized to receive six HMHB sessions targeted towards prenatal anxiety (with breastfeeding discussed in the final session), while both groups also received enhanced usual care. Breastfeeding was defined in four categories: early breastfeeding, exclusive early breastfeeding, recent breastfeeding, and exclusive recent breastfeeding. Early breastfeeding referred to the first 24 h after birth and recent breastfeeding referred to the last 24 h before an assessment at six-weeks postpartum. Potential confounders included were mother's age, baseline depression and anxiety levels, stress, social support, if the first pregnancy (or not) and history of stillbirth or miscarriage as well as child's gestational age, gender. Both intent-to-treat and per-protocol analyses were examined. Stratified analyses were also used to compare intervention efficacy for those with mild vs severe anxiety.

RESULTS

Out of the 1307 eligible women invited to participate, 107 declined to participate and 480 were lost to follow-up, resulting in 720 women who completed the postpartum assessment. Both intervention and control arms were similar on demographic characteristics (e.g. sex, age, income, family structure). In the primary intent-to-treat analysis, there was a marginal impact of the intervention on early breastfeeding (OR 1.38, 95% CI: 0.99-1.92; 75.4% (N = 273) vs. 69.0% (N = 247)) and a non-significant association with other breastfeeding outcomes (OR1.42, 95% CI: 0.89-2.27; (47) 12.9% vs. (34) 9.5%, exclusive early breastfeeding; OR 1.48, 95% CI: 0.94-2.35; 90% (N = 327) vs. 86% (N = 309), recent breastfeeding; OR1.01, 95% CI: 0.76-1.35; 49% (N = 178) vs 49% (N = 175) exclusive recent breastfeeding). Among those who completed the intervention's six core sessions, the intervention increased the odds of early breastfeeding (OR1.69, 95% CI:1.12-2.54; 79% (N = 154) vs. 69% (N = 247)) and recent breastfeeding (OR 2.05, 95% CI:1.10-3.81; 93% (N = 181) vs. 86% (N = 309)). For women with mild anxiety at enrolment, the intervention increased the odds of recent breastfeeding (OR 2.41, 95% CI:1.17-5.00; 92% (N = 137) vs. 83% (N = 123).

CONCLUSIONS

The study highlights the potential of CBT-based interventions like HMHB to enhance breastfeeding among women with mild perinatal anxiety, contingent upon full participation in the intervention.

Results of a cognitive behavior therapy-based intervention for antenatal anxiety on birth outcomes in Pakistan: a randomized control trial

Antenatal anxiety is among the risk factors for adverse birth outcomes, which are common in Pakistan. Between 2019 and 2022, we conducted a randomized controlled trial to evaluate the effects of the Happy Mother-Healthy Baby program, designed to reduce anxiety during pregnancy through use of Cognitive Behavior Therapy, on birth outcomes with 796 women in Rwalpindi, Pakistan. We performed intent-to-treat analysis and per protocol analyses. Intention-to-treat analyses showed no difference in the odds of low birthweight (LBW) (Adj. OR = 0.82, 95% CI 0.55-1.28 p = 0.37), preterm birth (PTB) (Adj. OR = 1.20 95% CI 0.83-1.71, p = 0.33) or small-for-gestational age (SGA) birth, (Adj. OR = 0.76, 95% CI 0.56-1.09, p = 0.16). Among completers who received ≥ 5 intervention sessions, the odds of LBW and SGA were 39% and 32% lower (Adj. OR = 0.61, 95% CI 0.43-0.87, p < 0.01; Adj. OR = 0.68, 95% CI 0.53-0.89, p < 0.01). The significant LBW and SGA results among the intervention completers suggest that the program may be effective when a sufficient dose is received. However, confirmation of these findings is needed due to the fact that randomization is not maintained in completer analyses.Clinical Trial Registration: ClinicalTrials.gov Identifier: NCT03880032, 19/03/2019.

Exploring preference for delivery methods for a psychosocial intervention for prenatal anxiety: A qualitative study from a tertiary care hospital in Pakistan

Objective

This qualitative study explores therapists' and participants' preferences for delivery methods (face-to-face and phone sessions) of a cognitive behavioral therapy-based psychosocial intervention for prenatal anxiety delivered in a tertiary care hospital.

Setting

The research was conducted in a randomized controlled trial in Pakistan, where a shift from face-to-face to phone-based therapy occurred during the coronavirus disease-2019 (COVID-19) pandemic.

Participants

Twenty in-depth interviews and a focus group discussion were conducted with participants and therapists, respectively. Transcripts were analyzed using thematic analysis.

Results

Participants generally preferred face-to-face sessions for rapport building, communication, and comprehension. However, barriers like venue accessibility, childcare, and lack of family support hindered engagement. Telephone sessions were favored for easy scheduling and the comfort of receiving the session at home, but there were challenges associated with phone use, distractions at home, and family members' limited mental health awareness. A mix of face-to-face and telephone sessions was preferred, with rapport from in-person sessions carrying over to telephone interactions.

Conclusion

This study underscores the need for adaptable intervention delivery strategies that consider cultural norms, logistical challenges, and individual family dynamics. By combining the benefits of both delivery methods, mental health interventions can be optimized to effectively address prenatal anxiety and promote well-being in resource-constrained settings like Pakistan.

Anxiety-focused cognitive behavioral therapy delivered by non-specialists to prevent postnatal depression: a randomized, phase 3 trial

Anxiety experienced by women during pregnancy is highly prevalent, especially in resource-poor settings and strongly predicts postnatal common mental disorders (CMDs), anxiety and depression. We evaluated the effectiveness of an anxiety-focused early prenatal intervention on preventing postnatal CMDs. This study was a phase 3, two-arm, single-blind, randomized controlled trial conducted in Pakistan with women who were ≤22 weeks pregnant and had at least mild anxiety without clinical depression. Participants were randomized to the Happy Mother-Healthy Baby program, based on cognitive behavioral therapy, consisting of six one-on-one intervention sessions in pregnancy delivered by non-specialist providers, or to enhanced care alone. The primary outcome was major depression, generalized anxiety disorder or both at 6 weeks after delivery. Overall, 755 women completed postnatal assessments (380 (50.3%), intervention arm; 375 (49.7%) enhanced-care arm). The primary outcomes were met. Examined jointly, we found 81% reduced odds of having either a major depressive episode (MDE) or moderate-to-severe anxiety for women randomized to the intervention (adjusted odds ratio (aOR) = 0.19, 95% CI 0.14-0.28). Overall, 12% of women in the intervention group developed MDE at 6 weeks postpartum, versus 41% in the control group. We found reductions of 81% and 74% in the odds of postnatal MDE (aOR = 0.19, 95% CI 0.13-0.28) and of moderate-to-severe anxiety (aOR = 0.26, 95% CI 0.17-0.40), respectively. The Happy Mother-Healthy Baby program early prenatal intervention focusing on anxiety symptoms reduced postpartum CMDs. ClinicalTrials.gov identifier NCT03880032 .
