Nongovernmental Organization Practitioners' Perspectives on the Challenges and Solutions to Changing Handwashing Behavior in Older Children: A Qualitative Study.

BACKGROUND: Increasing handwashing with soap (HWWS) among older children (aged 5-14 years) can achieve a substantial public health impact. However, HWWS interventions targeting older children have had mixed success. Recent research has attempted to quantitatively identify effective intervention techniques; however, success is likely also influenced by the wider context of implementation. We explore nongovernmental organization (NGO) practitioners' perspectives on the challenges and solutions to HWWS interventions targeting older children to enhance understanding of what is required, beyond intervention content, for them to be effective. METHODS: We conducted in-depth, semistructured interviews in April-November 2020 with 25 practitioners employed across 11 NGOs and involved in HWWS interventions targeting older children in development and humanitarian settings. We used purposive and snowball sampling to recruit participants in roles at the global, national/regional, and local levels. Interviews were audio-recorded, transcribed, and thematically analyzed to identify challenges and solutions to HWWS interventions targeting older children. Results were organized according to program development cycle stages. RESULTS: Twelve themes relating to perceived challenges emerged: (1) lack of prioritization, (2) funding inconsistency, (3) insufficient formative research, (4) demand on resources, (5) unengaging intervention content, (6) non-enabling physical environments, (7) availability of skilled implementers, (8) reaching out-of-school children, (9) community mistrust, (10) lack of coordination, (11) lack of evaluation rigor, and (12) failure to assign older children's HWWS as a primary outcome in evaluations of hygiene interventions. Recommended solutions were at the intervention, organization, and sector levels. CONCLUSION: Intervention design and delivery are important for the success of HWWS interventions for older children, but contextual factors, such as the availability of human and material resources and the level of coordination within and beyond the NGO sector, should also be considered. NGOs need to prioritize HWWS promotion among older children and support programs accordingly.
