The prevention of arboviral diseases using mobile devices: a preliminary study of the attitudes and behaviour change produced by educational interventions.

Objectives: In Brazil, the National Policy for Dengue Control seeks to incorporate the lessons of national and international experience in dengue control, emphasising the need for health education activities. The objective of this study was to evaluate and compare knowledge, attitudes and behaviours related to the prevention of arboviruses before and after a two-month educational intervention using a learning platform on mobile devices.

Methods: This quasi-experimental study corresponds to the first phase of the project 'Impact of mobile learning in the prevention and management of complications caused by arboviruses (Zika, Dengue, Chikungunya) - ZIKAMOB', sponsored as part of the British Council Newton Fund.

Results: Thirty of the 93 participants were first-year undergraduate university students (36.7% male), and 63 were police officers (84.1% male). The pattern of attitudes and behaviour was very similar in both groups before the intervention. The students changed their attitudes and behaviour (P = 0.032) in relation to their engagements in actions for the prevention of arboviral diseases and several other activities related to house inspections and precautions with water tanks (P < 0.01). However, recycling and surveillance activities were not as effective in changing behaviour. Female participants showed more motivation to participate in preventive activities, but living alone and working were barriers to participation. Individuals who already perform selective waste collection and are cultivating gardens demonstrated both a positive attitude and a positive behaviour towards actions for the prevention of arboviral diseases.

Conclusion: Mobile learning and behaviour change theories might be successful as the basis for school-based and community-based interventions to avoid arboviruses. These outcomes need to be confirmed in broader future studies.
