Connections between online harassment and offline violence among youth in Central Thailand.

Increasing evidence indicates that face-to-face (offline) youth violence and online harassment are closely interlinked, but evidence from Asian countries remains limited. This study was conducted to quantitatively assess the associations between offline violence and online harassment among youth in Central Thailand. Students and out-of-school youth (n=1,234, age: 15-24 years) residing, studying, and/or working in a district in Central Thailand were surveyed. Participants were asked about their involvement in online harassment and in verbal, physical, sexual, and domestic types of offline violence, as perpetrators, victims, and witnesses within a 1-year period. Multivariable logistic regression was used to assess independent associations between different kinds of involvement in offline violence and online harassment. Perpetration and victimization within the past year were both reported by roughly half of the youth both online and offline. Over three quarters had witnessed violence or harassment. Perpetrating online harassment was independently associated with being a victim online (adjusted odds ratio [AOR]=10.1; 95% CI [7.5, 13.6]), and perpetrating offline violence was independently associated with being a victim offline (AOR=11.1; 95% CI [8.1, 15.0]). Perpetrating online harassment was independently associated with perpetrating offline violence (AOR=2.7; 95% CI [1.9, 3.8]), and being a victim online was likewise independently associated with being a victim offline (AOR=2.6; 95% CI [1.9, 3.6]). Online harassment and offline violence are interlinked among Thai youth, as in other countries studied so far. Interventions to reduce either might best address both together.
