Domestic violence continues to be a significant social challenge with far-reaching effects on the well-being of individuals and communities. This study investigated the perceived effects of domestic violence among adolescents residing in the Igando community, Lagos State. Employing a descriptive research design, the study targeted adolescents living in Igando. Using a convenience sampling technique, 185 respondents were selected, and data were gathered through structured questionnaires. Of the administered questionnaires, 180 were returned, yielding a 97% response rate. Data analysis involved frequency counts, simple percentage distributions, means, standard deviations, and hypothesis testing using the chi-square test at a 0.05 significance level, performed with SPSS version 25.0.The findings revealed that 98.3% of respondents demonstrated significant awareness of domestic violence. Substance abuse was identified as a primary contributing factor, with 90.0% strongly agreeing and 10.0% agreeing to its influence. Furthermore, hypothesis testing indicated a statistically significant relationship between adolescents’ age and their awareness of the effects of domestic violence (P = 0.006). Based on these outcomes, the study recommends that midwives and healthcare professionals receive training to detect signs of domestic violence among adolescents and provide appropriate psychological referrals. Additionally, schools should integrate comprehensive domestic violence education into their curricula to enhance awareness and dispel misconceptions among students.
