Prevalence of technology facilitated and other gender-based violence among adolescent girls in Gqeberha, South Africa and its association with probable common mental disorders

Emerging evidence is raising alarms that technology facilitated gender-based violence (TF-GBV) is a growing public health concern with impacts on child wellbeing, yet little research on the topic has been conducted in middle-income country settings. This study aimed to investigate the prevalence of TF-GBV, other GBV, and their association with common mental disorder (CMD) symptoms among adolescent girls in South Africa. Trained enumerators facilitated surveys on exposure to physical and sexual violence with adolescent girls aged 10–19 from 14 low-income primary and secondary public schools. An index of TF-GBV assessed past-year exposure to acts such as public posting of sexual photos. CMD screening used Patient Health Questionnaire-2 and Generalized Anxiety Disorder-2 tools. Generalized estimating equations assessed associations between violence (TF-GBV, other GBV, or both) and CMD. A total of 1,540 adolescent girls participated in the study. Most participants identified as Black (84%). CMD symptoms were more prevalent among girls in secondary school (37%) than primary school (10%). All forms of past-year GBV were more prevalent among secondary school girls, including TF-GBV (43% vs. 11% in primary school girls). Exposure to both TF-GBV and other forms of GBV were significantly associated with a 3.68 times higher risk of CMD (aRR = 3.68, 95% CI 2.42–5.62) after adjusting for demographics and partnership status. These findings underscore the need for targeted content to address TF-GBV within existing GBV programs, and its impact on mental health among adolescent girls in similar contexts.
