            Evaluation of a community-based mobile video breastfeeding intervention in Khayelitsha, South Africa: The Philani MOVIE cluster-randomized controlled trial

            Background In South Africa, breastfeeding promotion is a national health priority. Regular perinatal home visits by community health workers (CHWs) have helped promote exclusive breastfeeding (EBF) in underresourced settings. Innovative, digital approaches including mobile video content have also shown promise, especially as access to mobile technology increases among CHWs. We measured the effects of an animated, mobile video series, the Philani MObile Video Intervention for Exclusive breastfeeding (MOVIE), delivered by a cadre of CHWs (“mentor mothers”). Methods and findings We conducted a stratified, cluster-randomized controlled trial from November 2018 to March 2020 in Khayelitsha, South Africa. The trial was conducted in collaboration with the Philani Maternal Child Health and Nutrition Trust, a nongovernmental community health organization. We quantified the effect of the MOVIE intervention on EBF at 1 and 5 months (primary outcomes), and on other infant feeding practices and maternal knowledge (secondary outcomes). We randomized 1,502 pregnant women in 84 clusters 1:1 to 2 study arms. Participants’ median age was 26 years, 36.9% had completed secondary school, and 18.3% were employed. Mentor mothers in the video intervention arm provided standard-of-care counseling plus the MOVIE intervention; mentor mothers in the control arm provided standard of care only. Within the causal impact evaluation, we nested a mixed-methods performance evaluation measuring mentor mothers’ time use and eliciting their subjective experiences through in-depth interviews. At both points of follow-up, we observed no statistically significant differences between the video intervention and the control arm with regard to EBF rates and other infant feeding practices [EBF in the last 24 hours at 1 month: RR 0.93 (95% CI 0.86 to 1.01, P = 0.091); EBF in the last 24 hours at 5 months: RR 0.90 (95% CI 0.77 to 1.04, P = 0.152)]. We observed a small, but significant improvement in maternal knowledge at the 1-month follow-up, but not at the 5-month follow-up. The interpretation of the results from this causal impact evaluation changes when we consider the results of the nested mixed-methods performance evaluation. The mean time spent per home visit was similar across study arms, but the intervention group spent approximately 40% of their visit time viewing videos. The absence of difference in effects on primary and secondary endpoints implies that, for the same time investment, the video intervention was as effective as face-to-face counseling with a mentor mother. The videos were also highly valued by mentor mothers and participants. Study limitations include a high loss to follow-up at 5 months after premature termination of the trial due to the COVID-19 pandemic and changes in mentor mother service demarcations. Conclusions This trial measured the effect of a video-based, mobile health (mHealth) intervention, delivered by CHWs during home visits in an underresourced setting. The videos replaced about two-fifths of CHWs’ direct engagement time with participants in the intervention arm. The similar outcomes in the 2 study arms thus suggest that the videos were as effective as face-to-face counselling, when CHWs used them to replace a portion of that counselling. Where CHWs are scarce, mHealth video interventions could be a feasible and practical solution, supporting the delivery and scaling of community health promotion services. Trial registration The study and its outcomes were registered at clinicaltrials.gov (# NCT03688217 ) on September 27, 2018. Maya Adam and colleagues study a video intervention, delivered by community health workers, to promote breastfeeding in South Africa. Why was this study done? Perinatal home visits from trained community health workers (CHWs) have shown promise for increasing the prevalence of exclusive breastfeeding, a national health priority in South Africa. Video-based, mobile health interventions, incorporating narratives and entertainment–education (E–E), have demonstrated potential for engaging community members and improving health knowledge. Few studies have measured the effect of integrating health promotion videos into CHW workflows in underresourced settings. What did the researchers do and find? We developed a mobile, video breastfeeding intervention to be delivered by CHWs (“mentor mothers”) employed by an established community health program during their home visits with 1,502 pregnant participants. We randomized mentor mothers 1:1 to intervention and control arm. All participants served by the same mentor mother either received or did not receive the intervention. In addition to the causal impact evaluation using a randomized controlled trial, we performed a mixed-methods performance evaluation measuring mentor mothers’ time use and gaining insights into mentor mothers’ subjective experiences with the intervention through in-depth interviews. The randomized controlled trial showed no difference in effects between the intervention and control arms. The performance evaluation results showed that mentor mothers in the intervention arm spent approximately 40% of their visit time viewing videos with their participants. What do these findings mean? Instead of serving as a complement to the standard of care, mentor mothers in the video intervention group used it to replace two-fifths of their face-to-face counseling time with participants. The absence of difference between infant feeding outcomes in the 2 study arms implies that the video intervention was as effective as face-to-face counseling, when the CHWs used it to replace a portion of that counselling. Used in addition to face-to-face engagement, video interventions could boost the health promotion efforts of CHWs, and, where CHWs are not available or extremely scarce, mobile video health interventions could become an increasingly feasible and practical solution for the delivery and scaling of community health promotion services. Future research should explore alternative delivery channels for mobile video E–E health interventions and measure, across channels, the potential for these interventions to (a) increase access to health promotion in underresourced communities; (b) support existing CHW programs; and (c) improve health behaviors and outcomes.

              Effectiveness and costs associated with a lay counselor–delivered, brief problem-solving mental health intervention for adolescents in urban, low-income schools in India: 12-month outcomes of a randomized controlled trial

              Background Psychosocial interventions for adolescent mental health problems are effective, but evidence on their longer-term outcomes is scarce, especially in low-resource settings. We report on the 12-month sustained effectiveness and costs of scaling up a lay counselor–delivered, transdiagnostic problem-solving intervention for common adolescent mental health problems in low-income schools in New Delhi, India. Methods and findings Participants in the original trial were 250 school-going adolescents (mean [M] age = 15.61 years, standard deviation [SD] = 1.68), including 174 (69.6%) who identified as male. Participants were recruited from 6 government schools over a period of 4 months (August 20 to December 14, 2018) and were selected on the basis of elevated mental health symptoms and distress/functional impairment. A 2-arm, randomized controlled trial design was used to examine the effectiveness of a lay counselor–delivered, problem-solving intervention (4 to 5 sessions over 3 weeks) with supporting printed booklets (intervention arm) in comparison with problem solving delivered via printed booklets alone (control arm), at the original endpoints of 6 and 12 weeks. The protocol was modified, as per the recommendation of the Trial Steering Committee, to include a post hoc extension of the follow-up period to 12 months. Primary outcomes were adolescent-reported psychosocial problems (Youth Top Problems [YTP]) and mental health symptoms (Strengths and Difficulties Questionnaire [SDQ] Total Difficulties scale). Other self-reported outcomes included SDQ subscales, perceived stress, well-being, and remission. The sustained effects of the intervention were estimated at the 12-month endpoint and over 12 months (the latter assumed a constant effect across 3 follow-up points) using a linear mixed model for repeated measures and involving complete case analysis. Sensitivity analyses examined the effect of missing data using multiple imputations. Costs were estimated for delivering the intervention during the trial and from modeling a scale-up scenario, using a retrospective ingredients approach. Out of the 250 original trial participants, 176 (70.4%) adolescents participated in the 12-month follow-up assessment. One adverse event was identified during follow-up and deemed unrelated to the intervention. Evidence was found for intervention effects on both SDQ Total Difficulties and YTP at 12 months (YTP: adjusted mean difference [AMD] = −0.75, 95% confidence interval [CI] = −1.47, −0.03, p = 0.04; SDQ Total Difficulties: AMD = −1.73, 95% CI = −3.47, 0.02, p = 0.05), with stronger effects over 12 months (YTP: AMD = −0.98, 95% CI = −1.51, −0.45, p < 0.001; SDQ Total Difficulties: AMD = −1.23, 95% CI = −2.37, −0.09; p = 0.03). There was also evidence for intervention effects on internalizing symptoms, impairment, perceived stress, and well-being over 12 months. The intervention effect was stable for most outcomes on sensitivity analyses adjusting for missing data; however, for SDQ Total Difficulties and impairment, the effect was slightly attenuated. The per-student cost of delivering the intervention during the trial was $3 United States dollars (USD; or $158 USD per case) and for scaling up the intervention in the modeled scenario was $4 USD (or $23 USD per case). The scaling up cost accounted for 0.4% of the per-student school budget in New Delhi. The main limitations of the study’s methodology were the lack of sample size calculations powered for 12-month follow-up and the absence of cost-effectiveness analyses using the primary outcomes. Conclusions In this study, we observed that a lay counselor–delivered, brief transdiagnostic problem-solving intervention had sustained effects on psychosocial problems and mental health symptoms over the 12-month follow-up period. Scaling up this resource-efficient intervention is an affordable policy goal for improving adolescents’ access to mental health care in low-resource settings. The findings need to be interpreted with caution, as this study was a post hoc extension, and thus, the sample size calculations did not take into account the relatively high attrition rate observed during the long-term follow-up. Trial registration ClinicalTrials.gov NCT03630471 . Kanika Malik, Daniel Michelson, and colleagues study the sustained effectiveness of a lay counsellor-delivered problem solving intervention to mental health of adolescents enrolled in low-income schools in New Delhi, India. Why was this study done? The PRemIum for aDolEscents (PRIDE) is a research program that aims to develop a transdiagnostic, stepped care intervention model to address common adolescent mental health problems (anxiety, depression, and conduct difficulties) in low-resource settings. The intervention model comprises a brief problem-solving intervention (“Step 1”), followed by a higher-intensity personalized psychological treatment (“Step 2”) for adolescents with persistent problems. We previously reported on short-term outcomes from a randomized controlled trial of the first-line problem-solving intervention delivered by lay counselors in secondary schools serving low-income communities in New Delhi, India. The current study examined the sustained effectiveness and costs of scaling up the counselor-led problem-solving intervention compared to printed problem-solving materials without counselor input. What did the researchers do and find? We followed up the original trial participants at 12 months after randomization and collected adolescent-reported outcomes, as well as data on intervention costs using a retrospective ingredients approach. The primary analysis showed sustained intervention effects on both psychosocial problems and mental health symptoms. The economic analysis showed that the counselor-led problem-solving intervention can be scaled up at a small percentage of the per-student budgetary allocation in government-run schools in New Delhi, India. What do these findings mean? Despite its brevity and delivery by lay counselors, the problem-solving intervention showed sustained effectiveness. Scaling up this low-cost intervention represents an affordable policy goal for improving access to school-based mental health care for adolescents in India and, potentially, in other low-resource settings.
