Acceptability of peer learning and education approach on malaria prevention (PLEA-malaria) through primary schools communities in rural Ethiopia: peer educators’ perspectives

BACKGROUND: Evidence on peer educators’ experiences of implementing the school-based educational interventions on malaria prevention would be used as inputs for malaria eliminating efforts. This study explored the acceptability of the school-based peer-learning and education approach on malaria prevention (PLEA-malaria) among peer educators in Ethiopia. METHODS: This process evaluation study was aimed to examine the success of the school-based PLEA-malaria that was implemented in 75 primary schools in Jimma from 2017 to 2019. A mixed research method was employed to collect post-intervention data from 404 peer educators and key stakeholders. Data were collected using a structured questionnaire and interview guide. Multivariable linear regression modelling was performed using SPSS software version 26.0. Atlas ti 7.5 for windows was used to analyse the qualitative data. The result was presented by triangulating the findings of the qualitative and quantitative methods. RESULTS: The mean score (M, range = R) of acceptability of PLEA-malaria was (M = 20.20, R = 6–30). The regression modelling showed that age; (β = 0.264, 95% CI 0.266 to 0.632), GPA; (β = 0.106, 95% CI 0.008 to 0.074), parental readiness for malaria education; (β = 0.184, 95% CI 0.711 to 2.130), frequency of peer education; (β = 0.232, 95% CI 1.087 to 2.514) and team spirit; (β = 0.141, 95% CI 0.027 to 0.177) were positively associated with the acceptability while this relationship was negative for the number of ITN in the household; (β = − 0.111, 95% CI − 1.182 to -0.13) and frequency of parent-student communication; (β = − 0.149, 95% CI − 1.201 to − 0.293). The qualitative study identified facilitators of PLEA-malaria (e.g. team formation process, outcome efficacy, presence of schools’ structures, schools priority, and support) and barriers (e.g. low commitments, threat appraisal, response efficacy, and PLEA-malaria implementation gaps). CONCLUSION: The results suggested that the acceptability of the school-based PLEA-malaria was higher implying the strategy is promising in promoting malaria prevention in primary schools. Considering factors related to personal, access to malaria preventive services, school system, and social support in education and behaviour change interventions would be important to improve the acceptability. The relationship about how an improvement in the level of acceptability would in turn influences malaria preventive behaviours among the students should be investigated.
