ABSTRACT: Abstract

Objective

To determine whether a water, sanitation and hygiene intervention could change hygiene behaviours thought to be important for trachoma control.

Methods

We conducted a cluster-randomized trial in rural Ethiopia from 9 November 2015 to 5 March 2019. We randomized 20 clusters to an intervention consisting of water and sanitation infrastructure and hygiene promotion and 20 clusters to no intervention. All intervention clusters received a primary-school hygiene curriculum, community water point, household wash station, household soap and home visits from hygiene promotion workers. We assessed intervention fidelity through annual household surveys.

Findings

Over the 3 years, more wash stations, soap and latrines were seen at households in the intervention clusters than the control clusters: risk difference 47 percentage points (95% confidence interval, CI: 41–53) for wash stations, 18 percentage points (95% CI: 12–24) for soap and 12 percentage points (95% CI: 5–19) for latrines. A greater proportion of people in intervention clusters reported washing their faces with soap (e.g. risk difference 21 percentage points; 95% CI: 15–27 for 0–5 year-old children) and using a latrine (e.g. risk difference 9 percentage points; 95% CI: 2–15 for 6–9 year-old children). Differences between the intervention and control arms were not statistically significant for many indicators until the programme had been implemented for at least a year; they did not decline during later study visits.

Conclusion

The community- and school-based intervention was associated with improved hygiene access and behaviours, although changes in behaviour were slow and required several years of the intervention.

Project description:ABSTRACT Background: The high prevalence of trauma exposure and consequent post-traumatic stress disorder (PTSD) is well documented in low- and middle-income countries, and most individuals with PTSD have limited access to treatment in these settings. Freely available internet-based interventions, such as PTSD Coach (web-based and mobile application), can help to address this gap and improve access to and efficiency of care. Objective: We conducted two pilot studies to evaluate the feasibility, acceptability, and preliminary effectiveness of PTSD Coach in a South African resource-constrained context. Method: Pilot 1: Participants with PTSD (n = 10) were randomized to counsellor-supported PTSD Coach Online (PCO) or enhanced treatment as usual. Pilot 2: Participants (n = 10) were randomized to counsellor-supported PTSD Coach Mobile App or self-managed PTSD Coach Mobile App. Feasibility and acceptability were assessed by comparing attrition rates (loss to follow-up), reviewing participant and counsellor feedback contained in fieldnotes, and analysing data on the ‘Perceived helpfulness of the PTSD Coach App’ (Pilot 2). PTSD symptom severity was assessed with the Clinician Administered PTSD Scale for DSM-5 (CAPS-5), changes between treatment and control groups were compared, the reliable change index (RCI) was calculated, and clinically significant changes were determined. Results: Three participants in Pilot 1 and two participants in Pilot 2 were lost to follow-up. Fieldnotes indicated that PTSD Coach Mobile App addressed identified computer literacy challenges in Pilot 1 (PCO); and a shorter duration of intervention (from 8 to 4 weeks) was associated with less attrition. The RCI indicated that four participants in Pilot 1 and eight participants in Pilot 2 experienced significant improvement in PTSD symptom severity. Conclusions: The preliminary results suggest that both platforms can alleviate PTSD symptoms, and that the involvement of volunteer counsellors is beneficial. The use of PTSD Coach Mobile App may be more feasible than the online version (PCO) in our setting. HIGHLIGHTS Research on supported PTSD Coach interventions is limited in resource-constrained settings. Both volunteer counsellor-supported PTSD Coach Online and the PTSD Coach Mobile App showed preliminary reliable and clinically significant changes. The use of PTSD Coach Mobile App seems more feasible than the volunteer counsellor-supported PTSD Coach Online.
