Child sexual abuse (CSA) is associated with many repercussions on adolescents’ mental health, including suicidal ideation. Yet, the mechanisms linking CSA to adverse outcomes have rarely been investigated within a longitudinal design. The current study aimed to examine the role of affect dysregulation in the association between depressive symptoms and suicidal ideation 1year after the first assessment in a sample of 119 sexually abused adolescent girls. An integrative mediational model was conceptualized to examine the explicatory role of affect dysregulation (Time 2) in the association between depressive symptoms (Time 1) and suicidal ideation (Time 3). Approximately 31% of the girls reported suicidal ideation at Time 3. Path analysis with logistic regressions revealed that the association between depressive symptoms and suicidal ideation presence was partly explained by affect dysregulation, which increased the risk of suicidal ideation presence by 18.4%, OR = 1.18, 95% CI [1.07, 1.33]. The integrative model explained 21.5% of the variance in suicidal ideation. These findings identify potential predictors of suicidal ideation among sexually abused adolescent girls. This present study highlights the role of affect dysregulation in the presence of suicidal ideation and provides potential targets for intervention practices when working with adolescent girl victims of CSA. As such, interventions for this vulnerable population should aim to decrease depressive symptoms and affect dysregulation to reduce suicidal risk.

性虐待少女自杀意念的纵向研究：抑郁症状和影响失调作为预测因素

儿童性虐待 (CSA) 与对青少年心理健康的许多影响有关，包括自杀意念。然而，很少在纵向设计中研究将 CSA 与不良结果联系起来的机制。目前的研究旨在对 119 名遭受性虐待的少女样本进行首次评估后 1 年，研究情感失调在抑郁症状和自杀意念之间的关系中的作用。一个综合中介模型被概念化，以检查情感失调（时间 2）在抑郁症状（时间 1）和自杀意念（时间 3）之间的关联中的解释性作用。大约 31% 的女孩在时间 3 报告有自杀意念。OR = 1.18, 95% CI [1.07, 1.33]。综合模型解释了 21.5% 的自杀意念差异。这些发现确定了性虐待少女自杀意念的潜在预测因素。本研究强调了存在自杀意念时情感失调的作用，并为与 CSA 的青春期女孩受害者合作时的干预实践提供了潜在的目标。因此，针对这一弱势群体的干预措施应旨在减少抑郁症状并影响失调，以降低自杀风险。
