Suicide-related behaviors are prevalent among college students, and several mental health problems associated with increased suicide risk have increased over time. Furthermore, notable cultural events (e.g., political changes, COVID-19) have occurred in the past decade, which likely impact trends in suicide-related behaviors. The current study examined how the prevalence of nonsuicidal self-injury (NSSI), suicidal ideation (SI), and suicide attempts has changed from 2012 to 2022 across three different universities.
Archival datasets from multiple years of college student survey data were compiled, and different measures of NSSI, SI, and suicide attempts were dichotomized to assess prevalence. Chi-square goodness-of-fit tests were used to identify changes in suicide-related behaviors across time.
Results indicated significant increases in the prevalence of most behaviors across each university, with most increases occurring after 2018. Despite sharing a general trend of increased suicide-related behaviors, each university differed considerably in their respective trends between various timepoints, suggesting that unique factors may differentially contribute to growing risk among college students.
Overall, the current study identifies increasing trends in suicide-related behaviors over the past decade and highlights the value of investigating these behaviors at the university level.
自杀相关行为在大学生中很普遍，一些与自杀风险增加相关的心理健康问题也随着时间的推移而增多。此外，在过去十年中发生了一些重大文化事件（如政治变革、新冠疫情），这可能影响自杀相关行为的趋势。本研究调查了2012年至2022年期间三所不同大学中非自杀性自伤（NSSI）、自杀意念（SI）和自杀未遂的发生率是如何变化的。
收集了多年大学生调查数据的档案数据集，并将NSSI、SI和自杀未遂的不同测量指标进行二分法处理以评估发生率。采用卡方拟合优度检验来确定自杀相关行为随时间的变化。
结果表明，每所大学中大多数行为的发生率都显著增加，大多数增加发生在2018年之后。尽管自杀相关行为总体呈增加趋势，但各大学在不同时间点的各自趋势差异很大，这表明独特因素可能对大学生中不断增加的风险有不同的影响。
总体而言，本研究确定了过去十年中自杀相关行为的增加趋势，并强调了在大学层面调查这些行为的价值。
