Behaviors that put adolescents at risk frequently occur together. To help identify high-risk adolescents, we analyzed a national, self-reported behavior survey of high school students to assess the suitability of fighting as a marker for students with multiple problem behaviors.
A cross-sectional cluster survey of 11,631 U.S. high school students in 1990 was used to compare the prevalence of recent problem behaviors among all students and those who fight.
One (8%) of every 12 students was in a fight during the 30 days before the survey. Reported problem behaviors were prevalent among fighters: during the previous 12 months, 24% attempted suicide; during the previous 30 days, 26% carried a firearm, 13% used cocaine, and 39% drove a motor vehicle while intoxicated; during the previous 3 months 41% had two or more sex partners; and 45% had sexual intercourse and did not use a condom the last time they had sex. Of all students, fighters accounted for 22% of those who reported attempting suicide, 49% carrying a firearm, 46% using cocaine, 18% driving while intoxicated, 25% having sex with multiple partners, and 11% not using condoms. Three or more of these six problem behaviors were reported by 26% of the fighters. The problem behaviors were all positively correlated, and the first principal component accounted for 35% of the total variation among the individual variables.
使青少年处于危险中的行为常常同时出现。为了帮助识别高危青少年，我们分析了一项针对高中生的全国性自我报告行为调查，以评估打架作为多种问题行为学生的一个标志的适用性。
采用1990年对11631名美国高中生进行的横断面整群调查，比较所有学生和打架学生中近期问题行为的发生率。
在调查前30天内，每12名学生中有1名（8%）参与过打架。打架学生中报告的问题行为很普遍：在过去12个月里，24%的人曾试图自杀；在过去30天里，26%的人携带枪支，13%的人使用可卡因，39%的人在醉酒时驾驶机动车；在过去3个月里，41%的人有两个或更多性伴侣；45%的人有过性行为且上次性行为时未使用避孕套。在所有学生中，打架学生占报告曾试图自杀者的22%、携带枪支者的49%、使用可卡因者的46%、醉酒驾驶者的18%、有多个性伴侣者的25%以及未使用避孕套者的11%。26%的打架学生报告了这六种问题行为中的三种或更多种。这些问题行为均呈正相关，第一个主成分占个体变量总变异的35%。
