The association between loneliness and suicidality has been documented in many studies, but these studies have been limited by cross-sectional designs and the use of adult-only populations. The purpose of the current study was to overcome these limitations by (a) investigating whether the link between loneliness and suicidal thoughts and behaviors occurs cross-sectionally, longitudinally, or both and (b) investigating how the link between loneliness and suicidality might be influenced by different demographic variables, including gender, ethnicity, and socioeconomic status. Logistic regression analyses were used to analyze data from a large sample (N = 937) of youth from the NICHD Study of Early Child Care. Results indicated that loneliness at age 15 years was concurrently associated with both suicidal ideation and suicidal behavior at age 15 years. Loneliness in middle childhood was longitudinally associated with suicidal behaviors at age 15 years, but not with suicidal ideation at age 15 years. None of the demographic characteristics influenced these associations.
许多研究都记录了孤独感与自杀倾向之间的关联，但这些研究受到了横断面设计和仅使用成年人样本的限制。本研究的目的是通过（a）研究孤独感与自杀意念和行为之间的联系是同时存在于横断面、纵向还是两者兼有，以及（b）研究孤独感与自杀倾向之间的联系可能会受到性别、种族和社会经济地位等不同人口统计学变量的影响，来克服这些局限性。逻辑回归分析被用于分析来自 NICHD 早期儿童保育研究的一个大样本（N=937）的青年数据。结果表明，15 岁时的孤独感与 15 岁时的自杀意念和自杀行为同时相关。儿童中期的孤独感与 15 岁时的自杀行为呈纵向相关，而与 15 岁时的自杀意念无关。这些关联不受任何人口统计学特征的影响。
