Adolescence and emerging adulthood are developmental phases in which the exploration of one's own sexuality takes on a high priority, which can increase the risk of risky sexual behavior. Due to technological advances, (non-consensual) sexting has increased among young people and has become an integral part of their sexual socialization. Therefore, the main objective of this study was to examine non-consensual sexting (both victimization and perpetration) among adolescents and emerging adults and to identify potential risk factors associated with non-consensual sexting using routine activity theory. The sample consisted of a total of 3514 adolescents aged 10–17 years (43% males; 57% females) and 3674 emerging adults aged 18–25 years (23% males; 77% females) from Bosnia and Herzegovina and Croatia. The results showed that both male adolescents and emerging adults were at higher risk for experiencing non-consensual sexting victimization. Personal factors such as gender, age, social bond, and routine cell phone activity predicted the risk of becoming a victim of non-consensual sexting in adolescents. For emerging adults, gender, social connection to friends, and routine cell phone use predicted the risk of becoming a victim of non-consensual sexting. Relationship status and routine cell phone activity predicted the forwarding of other sexts for both age groups. According to international scientific research and the findings of this particular study, we can conclude that the study of personal factors and routine variables helps understand non-consensual sexting among youth but is also essential in planning educational resources and preventive activities.

青春期和成年初期是对自己性行为的探索处于高度优先地位的发展阶段，这可能会增加危险性行为的风险。由于技术进步，（未经同意的）色情短信在年轻人中有所增加，并已成为他们性社会化不可或缺的一部分。因此，本研究的主要目的是调查青少年和新兴成年人中的非自愿性短信（包括受害和犯罪），并利用常规活动理论确定与非自愿性短信相关的潜在风险因素。该样本包括来自波斯尼亚和黑塞哥维那以及克罗地亚的 3514 名 10-17 岁青少年（43% 男性；57% 女性）和 3674 名 18-25 岁青少年（23% 男性；77% 女性）。结果表明，男性青少年和新兴成年人遭受未经同意的性短信受害的风险较高。性别、年龄、社会关系和日常手机活动等个人因素预测了青少年成为未经同意的色情短信受害者的风险。对于新兴成年人来说，性别、与朋友的社交联系以及手机的日常使用预示着成为未经同意的性短信受害者的风险。关系状态和日常手机活动预测了两个年龄段的其他性短信的转发。根据国际科学研究和这项特定研究的结果，我们可以得出结论，对个人因素和常规变量的研究有助于了解青少年中未经同意的性短信，而且对于规划教育资源和预防活动也至关重要。
