Childhood Sexual Abuse (CSA) is a menace to society and has long-lasting effects on the mental health of the survivors. From time to time CSA survivors are haunted by various mental health issues in their lifetime. Proper care and attention towards CSA survivors facing mental health issues can drastically improve the mental health conditions of CSA survivors. Previous works leveraging online social media (OSM) data for understanding mental health issues haven't focused on mental health issues in individuals with CSA background. Our work fills this gap by studying Reddit posts related to CSA to understand their mental health issues. Mental health issues such as depression, anxiety, and Post-Traumatic Stress Disorder (PTSD) are most commonly observed in posts with CSA background. Observable differences exist between posts related to mental health issues with and without CSA background. Keeping this difference in mind, for identifying mental health issues in posts with CSA exposure we develop a two-stage framework. The first stage involves classifying posts with and without CSA background and the second stage involves recognizing mental health issues in posts that are classified as belonging to CSA background. The top model in the first stage is able to achieve accuracy and f1-score (macro) of 96.26% and 96.24%. and in the second stage, the top model reports hamming score of 67.09%.

翻译：童年性虐待（CSA）对社会构成威胁，并对幸存者的心理健康产生长期影响。CSA幸存者一生中时常遭受各种心理健康问题的困扰。对面临心理健康问题的CSA幸存者提供适当护理和关注，可显著改善其心理健康状况。先前利用在线社交媒体（OSM）数据理解心理健康问题的研究未聚焦于具有CSA背景个体的心理健康问题。本研究通过分析Reddit上与CSA相关的帖子来填补这一空白，以理解其心理健康问题。抑郁、焦虑和创伤后应激障碍（PTSD）等心理健康问题在具有CSA背景的帖子中最常出现。具有与不具有CSA背景的心理健康相关帖子之间存在可观察的差异。基于这一差异，为识别具有CSA暴露经历的帖子中的心理健康问题，我们开发了一个两阶段框架：第一阶段对帖子是否具有CSA背景进行分类，第二阶段识别被归类为具有CSA背景帖子中的心理健康问题。第一阶段最优模型准确率达96.26%，宏平均F1分数为96.24%；第二阶段最优模型汉明损失为67.09%。内容警告：建议读者谨慎阅读，因为本研究涉及儿童性虐待、猥亵等话题。
