How does Community-Led Total Sanitation (CLTS) affect latrine ownership? A quantitative case study from Mozambique.

ABSTRACT: BACKGROUND:Community-led total sanitation (CLTS) is a widely used, community-based approach to tackle open defecation and its health-related problems. Although CLTS has been shown to be successful in previous studies, little is known about how CLTS works. We used a cross-sectional case study to identify personal, physical, and social context factors and psychosocial determinants from the Risks, Attitudes, Norms, Abilities, and Self-Regulation (RANAS) model of behavior change, which are crucial for latrine ownership and analyze how participation in CLTS is associated with those determinants. METHODS:Structured interviews were conducted with 640 households in 26 communities, where CLTS had been completed before and compared to 6 control communities, all located in northern Mozambique in 2015. To identify crucial factors for latrine ownership, logistic regression analysis were conducted and mediation analysis were used to analyse the relationship between CLTS participation and latrine ownership mediated by factors identified by the logistic regression analyses. RESULTS:Mediation analysis reveal that the relationship of CLTS participation with probability of owning a latrine is mediated by social context factors and psychosocial determinants. Data analysis reveal that the probability of building a latrine depends on existing social context factors within the village, the behavior of others in the community, the (dis)approval of others of latrine ownership, personal self-confidence in latrine building, and a precise communication of the benefits of latrine ownership during a CLTS triggering event. CONCLUSIONS:By including activities to focus on the mentioned factors, CLTS could be improved. Exemplary adaptations are discussed.

Project description:RationaleOpen defecation is connected to poor health and child mortality, but billions of people still do not have access to safe sanitation facilities. Community-Led Total Sanitation (CLTS) promotes latrine construction to eradicate open defecation. However, the mechanisms by which CLTS works and how they can be improved remain unknown. The present study is the first to investigate the psychosocial determinants of CLTS in a longitudinal design. Furthermore, we tested whether CLTS can be made more effective by theory- and evidence-based interventions using the risks, attitudes, norms, abilities, and selfregulation (RANAS) model.MethodsA cluster-randomized controlled trial of 3216 households was implemented in rural Ghana. Communities were randomly assigned to classic CLTS, one of three RANAS-based interventions, or to the control arm. Prepost surveys at 6-month follow-up included standardized interviews assessing psychosocial determinants from the RANAS model. Regression analyses and multilevel mediation models were computed to test intervention effects and mechanisms of CLTS.ResultsLatrine coverage increased pre-post by 67.6% in all intervention arms and by 7.9% in the control arm (p < .001). The combination with RANAS-based interventions showed non-significantly greater effects than CLTS alone. The effects of CLTS on latrine construction were significantly mediated by changes in four determinants: others' behaviour and approval, self-efficacy, action planning and commitment. Changes in vulnerability, severity, and barrier planning were positively connected to latrine construction but not affected by CLTS.ConclusionThis study corroborates the effectiveness of CLTS in increasing latrine coverage, and additional activities can be improved further. Behaviour change techniques within CLTS that strengthened the relevant factors should be maintained. The study also recommends interventions based on the RANAS approach to improve CLTS. Further research is needed to understand the effects of RANAS-based interventions combined with CLTS at longer follow-up.

Project description:BackgroundLack of latrines remain a widespread health and environmental hazard in many developing countries. Low latrine utilization mostly affects the poor, rural and marginalized communities as the majority of those who do not use improved latrines live in rural areas where 90% of all open defecation takes place. The counterpart to this problem, Community-Led Total Sanitation, and hygiene (CLTSH) is an approach that involves facilitating a process to inspire and empower communities to stop open defecation and to build and use latrines in a participatory manner.ObjectiveThis study was aimed at assessing the Community Led Total Sanitation and Hygiene approach on improvement of latrine utilization in Laelay Maichew District of Central Zone, Northern Ethiopia.MethodsA comparative cross-sectional study was conducted in Laelay Maichew District of Central Zone, Northern Ethiopia from November 2016 to January 2017. The study subjects were randomly selected 388 households from CLTSH implemented kebeles and 388 households from CLTSH non-implemented kebeles. Systematic random sampling technique was used to select households among proportionally allocated sample frame of households. Then, Interview of household heads using semi-structured questionnaire was conducted to collect data. Finally, data were entered and analyzed using SPSS version 20.0. Bivariate Logistic regressions model was used to identify candidates of multiple logistic regressions. Those P-values < 0.25 were considered as candidates to multiple logistic regressions to determine independent factors of latrine utilization. Variables with Odds Ratio at 95% CI and P-value < 0.05 was considered statistically significant. The study obtained approval from Aksum University Institutional Review Board before its commencement.ResultThis study indicated that the level of latrine utilization and latrine availability in CLTSH implemented kebeles were greater than that of CLTSH Non-implemented kebeles. The finding of this study revealed that the rate of latrine utilization in the rural community of Laelay-matches district was about 47.4%, 95% CI (42.9%-51.8%). The majority (71.1%) of household in CLTSH implemented kebeles and (93.5%) of households in CLTSH non-implemented kebeles did not have hand washing facility near the latrine. Households which had no fresh excreta in around latrine were significantly 11.5 times higher than [AOR: 11.5, 95% CI (0.18, 50.2)] utilizing their latrine in CLTSH implemented kebeles.ConclusionThe study showed that the level of latrine utilization in CLTSH implemented and that of CLTSH non-implemented kebeles was low. Therefore, concerted efforts should be made by local and national governmental and non-governmental organization to should be used to promote behavioral change in the communities to implement community-led total sanitation and hygiene for improving latrine utilization.

Project description:We conducted a study to evaluate the sustainability of community-led total sanitation (CLTS) outcomes in Ethiopia and Ghana. Plan International, with local actors, implemented four CLTS interventions from 2012 to 2014: health extension worker-facilitated CLTS and teacher-facilitated CLTS in Ethiopia, and NGO-facilitated CLTS with and without training for natural leaders in Ghana. We previously evaluated these interventions using survey data collected immediately after implementation ended, and concluded that in Ethiopia health extension workers were more effective facilitators than teachers, and that in Ghana training natural leaders improved CLTS outcomes. For this study, we resurveyed 3831 households one year after implementation ended, and analyzed latrine use and quality to assess post-intervention changes in sanitation outcomes, to determine if our original conclusions were robust. In one of four interventions evaluated (health extension worker-facilitated CLTS in Ethiopia), there was an 8 percentage point increase in open defecation in the year after implementation ended, challenging our prior conclusion on their effectiveness. For the other three interventions, the initial decreases in open defecation of 8-24 percentage points were sustained, with no significant changes occurring in the year after implementation. On average, latrines in Ethiopia were lower quality than those in Ghana. In the year following implementation, forty-five percent of households in Ethiopia repaired or rebuilt latrines that had become unusable, while only 6% did in Ghana possibly due to higher latrine quality. Across all four interventions and three survey rounds, most latrines remained unimproved. Regardless of the intervention, households in villages higher latrine use were more likely to have sustained latrine use, which together with the high latrine repair rates indicates a potential social norm. There are few studies that revisit villages after an initial evaluation to assess sustainability of sanitation outcomes. This study provides new evidence that CLTS outcomes can be sustained in the presence of training provided to local actors, and strengthens previous recommendations that CLTS is not appropriate in all settings and should be combined with efforts to address barriers households face to building higher quality latrines.
