Pornography use is common among adolescents. However, there has been limited in-depth examination of cross-country differences in adolescent pornography use. Therefore, the main aim of the present study was to understand cross-jurisdictional differences in problematic pornography use (PPU) in 1810 adolescents from Spain and Mexico. The relationship between sociodemographic variables, loneliness, sexual risk behaviors, and religiosity with PPU and cross-jurisdictional differences between the two Spanish-speaking populations was assessed. In the Spanish sample, pornography use was a mediator of risky sexual behaviors, with this association being greater in males, older individuals, and those with a non-heterosexual orientation. In the Mexican sample, non-use of condoms was directly statistically predicted by older age, poor familial relationships, low religiosity, and more frequent pornography use. Jurisdictional differences in relationships between variables were observed in the two samples (Spanish and Mexican). Clinical implications and potential sociocultural factors that may underlie observed differences in the two Spanish-speaking cultures are considered and warrant additional investigation.

色情制品的使用在青少年中很常见。然而，对青少年色情制品使用的跨国差异的深入研究有限。因此，本研究的主要目的是了解来自西班牙和墨西哥的 1810 名青少年在问题色情制品使用 （PPU） 方面的跨辖区差异。评估了社会人口学变量、孤独感、性风险行为和宗教信仰与 PPU 之间的关系以及两个讲西班牙语的人群之间的跨辖区差异。在西班牙样本中，色情制品的使用是危险性行为的中介因素，这种关联在男性、老年人和非异性恋取向者中更大。在墨西哥样本中，不使用避孕套的比例直接由年龄较大、家庭关系差、宗教信仰低和更频繁地使用色情内容直接统计预测。在两个样本 （西班牙和墨西哥） 中观察到变量之间关系的管辖权差异。考虑了可能导致两种西班牙语文化差异的临床意义和潜在社会文化因素，并需要进一步调查。
