Technology-assisted cognitive-behavior therapy delivered by peers versus standard cognitive behavior therapy delivered by community health workers for perinatal depression: study protocol of a cluster randomized controlled non-inferiority trial

BACKGROUND

The lack of trained mental health professionals is a key barrier to scale-up of evidence-based psychological interventions in low and middle-income countries. We have developed an app that allows a peer with no prior experience of health-care delivery to deliver the cognitive therapy-based intervention for perinatal depression, the Thinking Healthy Programme (THP). This trial aims to assess the effectiveness and cost-effectiveness of this Technology-assisted peer-delivered THP versus standard face-to-face Thinking Healthy Programme delivered by trained health workers.

METHODS

We will employ a non-inferiority stratified cluster randomized controlled trial design comparing the two formats of intervention delivery. A total of 980 women in the second or third trimester of pregnancy with a diagnosis of Major Depressive Episode, evaluated with the Structured Clinical Interview for DSM-V Disorders (SCID), will be recruited into the trial. The unit of randomization will be 70 village clusters randomly allocated in a 1:1 ratio to the intervention and control arms. The primary outcome is defined as remission from major depressive episode at 3 months postnatal measured with the SCID. Data will also be collected on symptoms of anxiety, disability, quality of life, service use and costs, and infant-related outcomes such as exclusive breastfeeding and immunization rates. Data will be collected on the primary outcome and selected secondary outcomes (depression and anxiety scores, exclusive breastfeeding) at 6 months postnatal to evaluate if the improvements are sustained in the longer-term. We are especially interested in sustained improvement (recovery) from major depressive episode.

DISCUSSION

This trial will evaluate the effectiveness and cost-effectiveness of a technology-assisted peer-delivered cognitive behavioral therapy-based intervention in rural Pakistan. If shown to be effective, the novel delivery format could play a role in reducing the treatment gap for perinatal depression and other common mental disorders in LMIC.

TRIAL REGISTRATION

The trial was registered at Clinicaltrials.gov (NCT05353491) on 29 April 2022.

Adaptation and integration of the thinking healthy programme into pregnancy schools in Istanbul, Turkey

BACKGROUND

Perinatal mental health is a major public health concern. In Turkey, public hospitals operate pregnancy schools which provides an opportunity to integrate an evidence-based Thinking Healthy Programme (THP) for perinatal depression. The aim of this study is to adapt the THP for universal use in the group setting and to understand its acceptability and feasibility for integration into the existing antenatal care programme for both face-to-face and online delivery.

METHODS

Following an expert-led adaptation process using the Bernal Framework, field testing was conducted on a group of women and facilitators followed by in-depth interviews (n:8) and group discussions (n = 13). Data were analysed using Thematic Framework Analysis.

RESULTS

Minor but significant adaptations were made to the individually delivered THP for use in the universal group pregnancy schools. Initial findings indicate that the THP-group version was acceptable to its target population and could be integrated into the antenatal care plan for delivery during face-to-face and online group classes.

CONCLUSION

THP is transferable to the Turkish cultural and healthcare context. The THP-group version has the potential to add value to Turkey's existing perinatal healthcare programme.

Standardising Training of Nurses in an Evidence-Based Psychosocial Intervention for Perinatal Depression: Randomized Trial of Electronic vs. Face-to-Face Training in China

Background: Rates of perinatal depression in China are high. The Thinking Healthy Programme is a WHO-endorsed, evidence-based psychosocial intervention for perinatal depression, requiring five days of face-to-face training by a specialist trainer. Given the paucity of specialist trainers and logistical challenges, standardized training of large numbers of nurses is a major challenge for scaling up. We developed an electronic training programme (e-training) which eliminates the need for specialist-led, face-to-face training. The aim of this study was to evaluate the effectiveness of the e-training compared to conventional face-to-face training in nursing students. Methods: A single blind, non-inferiority, randomized controlled trial was conducted. One hundred nursing students from two nursing schools were randomly assigned to either e-training or conventional face-to-face training. Results: E-training was not inferior to specialist-led face-to-face training immediately post-training [mean ENhancing Assessment of Common Therapeutic factors (ENACT) score (M) 45.73, standard deviation (SD) 4.03 vs. M 47.08, SD 4.53; mean difference (MD) −1.35, 95% CI; (−3.17, 0.46), p = 0.14]. There was no difference in ENACT scores at three months [M = 42.16, SD 4.85 vs. M = 42.65, SD 4.65; MD = −0.481, 95% CI; (−2.35, 1.39), p = 0.61]. Conclusions: E-training is a promising tool with comparative effectiveness to specialist-led face-to-face training. E-training can be used for training of non-specialists for evidence-based psychosocial interventions at scale and utilized where there is a shortage of specialist trainers, but practice under supervision is necessary to maintain competence. However, continued practice under supervision may be necessary to maintain competence.

Improving access to psychosocial interventions for perinatal depression in low- and middle-income countries: lessons from the field

Over 90% women with perinatal depression in low and middle-income countries do not receive treatment. Scale-up of evidence-based psychosocial interventions is a key challenge. We developed the Thinking Healthy Programme (THP), a psychosocial intervention that can be delivered by non-specialist providers such as community health workers in primary and secondary care settings. Our research showed that three out of 4 women with perinatal depression who received the programme recovered, and there were beneficial effects on infant outcomes. In over a decade since the original research, policy and practice uptake of the programme globally has been promising. We describe factors contributing to this: the programme is relatively inexpensive and culturally transferable; the intervention can be integrated with existing maternal and child health programmes; the programme is amenable to 'task-sharing' via peers, nurses, community health-workers and other frontline workers; cascaded models of training and supervision, and the use of technology for training and delivery provide exciting future avenues for scaled-up implementation. These innovations are relevant to the neglected field of public mental health, especially in the post COVID19 era when rates of anxiety and depression are likely to rise globally.

Development of a Psychological Intervention to Address Anxiety During Pregnancy in a Low-Income Country

Background: One in five women suffer from anxiety during pregnancy. Untreated anxiety is a risk factor for postnatal depression and is associated with adverse birth outcomes. Despite the high prevalence of prenatal anxiety in low- and middle-income countries (LMICs), efforts to develop and evaluate context-specific interventions in these settings are lacking. We aimed to develop a culturally appropriate, feasible, and acceptable psychological intervention for perinatal anxiety in the context of a low-income population in Pakistan. Methods: We conducted this research in Rawalpindi District at the Obstetrics Department of the Holy Family Hospital, Rawalpindi Medical University a government facility catering to a mixture of low-income urban, peri-urban, and rural populations. We used a mixture of research methods to: a) investigate the clinical, cultural, and health-service delivery context of perinatal anxiety; b) select an evidence-based approach that suited the population and health-delivery system; c) develop an intervention with extensive reference documentation/manuals; and d) examine issues involved in its implementation. Qualitative data were collected through in-depth interviews and focus group discussions, and analyzed using framework analysis. Results: Informed by the qualitative findings and review of existing evidence-based practices, we developed the "Happy Mother, Healthy Baby" intervention, which was based on principles of cognitive behavior therapy. Its evidence-based elements included: developing an empathetic relationship, challenging thoughts, behavior activation, problem solving, and involving family. These elements were applied using a three-step approach: 1) learning to identify unhealthy or unhelpful thinking and behavior; 2) learning to replace unhealthy or unhelpful thinking and behavior with helpful thinking and behavior; and 3) practicing thinking and acting healthy. Delivered by non-specialist providers, the intervention used culturally appropriate illustrations and examples of healthy activities to set tasks in collaboration with the women to encourage engagement in helpful behaviors. Feedback from the non-specialist providers indicated that the intervention was acceptable, feasible, and perceived to be helpful by the women receiving it. Conclusion: This new psychosocial intervention for perinatal anxiety, based on principles of cognitive behavior therapy and delivered by non-specialists, has the potential to address this important but neglected condition in LMICs.

Delivering maternal mental health through peer volunteers: a 5-year report

BACKGROUND

Maternal depression affects one in five women in low-and middle income countries (LMIC) and has significant economic and social impacts. Evidence-based psychosocial interventions delivered by non-specialist health workers are recommended as first-line management of the condition, and recent studies on such interventions from LMIC show promising results. However, lack of human resource to deliver the interventions is a major bottle-neck to scale-up, and much research attention has been devoted to 'task-sharing' initiatives. A peer-delivered version of the World Health Organization's Thinking Healthy Programme for perinatal depression in Pakistan and India showed clinical, functional and social benefits to women at 3 months postpartum. The programme has been iteratively adapted and continually delivered for 5 years in Pakistan. In this report, we describe the extended intervention and factors contributing to the peers' continued motivation and retention, and suggest future directions to address scale-up challenges.

METHODS

The study was conducted in rural Rawalpindi. We used mixed methods to evaluate the programme 5 years since its initiation. The competency of the peers in delivering the intervention was evaluated using a specially developed Quality and Competency Checklist, an observational tool used by trainers to rate a group session on key areas of competencies. In-depth interviews explored factors contributing to the peer volunteers' continued motivation and retention, as well as the key challenges faced.

RESULTS

Our key findings are that about 70% of the peer volunteers inducted 5 years ago continued to be part of the programme, retaining their competency in delivering the intervention, with only token financial incentives. Factors contributing to sustained motivation included altruistic aspirations, enhanced social standing in the community, personal benefits to their own mental health, and the possibility for other avenues of employment. Long-term challenges included demotivation due to lack of certainty about the programme's future, increased requirement for financial incentivisation, the logistics of organising groups in the community, and resistance from some families to the need for ongoing care.

CONCLUSIONS

The programme, given the sustained motivation and competence of peer volunteers in delivering the intervention, has the potential for long-term sustainability in under-resourced settings and a candidate for scale-up.

Using technology to scale-up training and supervision of community health workers in the psychosocial management of perinatal depression: a non-inferiority, randomized controlled trial

BACKGROUND

The Thinking Healthy Programme (THP) is an evidence-based psychological intervention endorsed by the World Health Organization, tailored for non-specialist health workers in low- and middle-income countries. However, training and supervision of large numbers of health workers is a major challenge for the scale-up of THP. We developed a 'Technology-Assisted Cascaded Training and Supervision system' (TACTS) for THP consisting of a training application and cascaded supervision delivered from a distance.

METHODS

A single-blind, non-inferiority, randomized controlled trial was conducted in District Swat, a post-conflict area of North Pakistan. Eighty community health workers (called Lady Health Workers or LHWs) were randomly assigned to either TACTS or conventional face-to-face training and supervision by a specialist. Competence of LHWs in delivering THP post-training was assessed by independent observers rating a therapeutic session using a standardized measure, the 'Enhancing Assessment of Common Therapeutic factors' (ENACT), immediately post-training and after 3 months. ENACT uses a Likert scale to score an observed interaction on 18 dimensions, with a total score of 54, and a higher score indicating greater competence.

RESULTS

Results indicated no significant differences between health workers trained using TACTS and supervised from distance v. those trained and supervised by a specialist face-to-face (mean ENACT score M  =  24.97, s.d.  =  5.95 v. M =  27.27, s.d.  =  5.60, p  =  0.079, 95% CI 4.87-0.27) and at 3 months follow-up assessment (M  =  44.48, s.d.  =  3.97 v. M =  43.63, s.d.  =  6.34, p  =  0.53, CI -1.88 to 3.59).

CONCLUSIONS

TACTS can provide a promising tool for training and supervision of front-line workers in areas where there is a shortage of specialist trainers and supervisors.

Barefoot therapists: barriers and facilitators to delivering maternal mental health care through peer volunteers in Pakistan: a qualitative study

BACKGROUND

Perinatal depression is a public health problem in low and middle income countries. Although effective psychosocial interventions exist, a major limitation to their scale up is the scarcity of mental health professionals. The aim of this study was to explore the facilitators and barriers to the acceptability of peer volunteers (PVs)-volunteer lay women from the community with shared socio-demographic and life experiences with the target population-as delivery agents of a psychosocial intervention for perinatal depression in a rural area of Pakistan.

METHODS

This qualitative study was embedded in the pilot phase of a larger peer-delivered mental health programme. Forty nine participants were included: depressed mothers (n = 21), PVs (n = 8), primary health care staff (n = 5), husbands (n = 5) and mothers-in-law (n = 10). Data were collected through in-depth interviews and focus groups and analysed using the Framework Analysis approach.

RESULTS

The PVs were accepted as delivery agents by all key stakeholders. Facilitators included the PVs' personal attributes such as being local, trustworthy, empathetic, and having similar experiences of motherhood. The perceived usefulness and cultural appropriateness of the intervention and linkages with the primary health care (PHC) system was vital to their legitimacy and credibility. The PVs' motivation was important, and factors influencing this were: appropriate selection; effective training and supervision; community endorsement of their role, and appropriate incentivisation. Barriers included women's lack of autonomy, certain cultural beliefs, stigma associated with depression, lack of some mothers' engagement and resistance from some families.

CONCLUSION

PVs are a potential human resource for the delivery of a psychosocial intervention for perinatal depression in this rural area of Pakistan. The use of such delivery agents could be considered for other under-resourced settings globally.
