Child marriage is one of the issues that deprive many young girls of their basic rights and lives. The present study aimed to explore Iranian child brides’ experiences of the consequences of early marriage. The participants were women living in Tehran who had married at the age of 14–18 years. The analysis of the participants’ experiences revealed four main themes, including ‘underlying causes of early marriages’, ‘concerns and negative feelings’, ‘exposure to violence’, and ‘consequences of early marriages’. Awareness of these challenges can provide useful insights to be used by social workers and policymakers to further support these women.
