Consistent condom use tends to be limited in youth, which makes this group especially vulnerable for sexually transmitted infections (STIs) and unplanned pregnancies. It is known that sexual risk may vary as a function of behavioral intentions (e.g., condom use intention or having sex under the influence of alcohol), but no studies have yet characterized the sexual risk profiles considering behavioral intentions. This study utilizes latent class analysis (LCA) to explore the subtyping of behavioral intentions related to sexual risk in a community-based sample of adolescents aged 14 to 16 years from Spain. Multinomial logistic regression was used to assess the association between class membership and participants' sociodemographic variables (sex, age, educational level, socioeconomic status, and family situation), and behavioral variables (sexual experience and percentage of condom use). Among the 1557 participants, four latent classes of risk were identified: "Condom + drugs", "abstinent", "condom + no drugs", and "no condom + drugs". Differences in adolescents' sex, age, educational level, sexual experience, and condom use across latent classes were found. Findings highlight opportunities for psychologists, educators, and health-care providers to promote condom use in adolescents with differing sexual risk profiles. Increased understanding of behavioral intentions among adolescents may help to reduce sexual risk behaviors in this group.
青少年使用避孕套的行为往往不够稳定，这使得他们特别容易感染性传播感染（STIs）和意外怀孕。众所周知，性行为风险可能会随着行为意图（例如，使用避孕套的意图或在饮酒影响下发生性行为）的变化而变化，但目前还没有研究描述过考虑行为意图的性行为风险特征。本研究利用潜在类别分析（LCA）来探索西班牙 14 至 16 岁青少年社区样本中与性行为风险相关的行为意图的亚型。多项逻辑回归用于评估类别成员与参与者的社会人口统计学变量（性别、年龄、教育水平、社会经济地位和家庭状况）以及行为变量（性经验和避孕套使用率）之间的关联。在 1557 名参与者中，确定了四个风险潜在类别：“避孕套+毒品”、“禁欲”、“避孕套+无毒品”和“无避孕套+毒品”。在潜在类别中发现了青少年的性别、年龄、教育水平、性经验和避孕套使用情况的差异。研究结果突出了心理学家、教育工作者和医疗保健提供者在不同性行为风险特征的青少年中促进避孕套使用的机会。增加对青少年行为意图的理解可能有助于减少该群体的性行为风险行为。
