A study in China found a significant link between family and domestic violence (FDV) and suicidal and self-harm ideation (SSI). Utilizing data from the 2022 Psychology and Behavior Investigation, researchers discovered that about 44% of participants reported experiencing FDV, while 25% exhibited SSI. The study revealed that FDV notably increases the risk of SSI, with a risk ratio of 1.267. Anxiety was identified as a mediator in this relationship, with sleep disturbances exacerbating anxiety levels, further elevating SSI risk. Adolescents and the elderly were particularly vulnerable to SSI due to FDV, and gender differences were observed; controlling violence affected women more significantly, whereas insulting violence had a greater impact on men. The findings highlight the high prevalence of FDV and SSI in China and their critical association, emphasizing the need for targeted interventions based on age and gender differences to address these issues effectively. This research provides new insights into the mental health implications of FDV, suggesting that strategies for intervention should consider the specific needs of at-risk populations.
