Previous literature is severely limited in evaluation of psychometric properties of suicide screening methods in American Indian (AI) populations, despite the disproportionate burden of suicide faced within AI communities. The purpose of the current study was to examine the psychometric properties of the Suicidal Ideation Questionnaire-Junior (SIQ-JR) for AI youth using 2 community samples of AI adolescents from a Southwestern tribe. The present study sample was comprised of 114 participants (n = 91 and n = 23), ages 10-19 years of age, from 2 studies, both of which were administered the SIQ-JR within 90 days of an index suicide attempt. Findings indicated that a two-factor model resulted in appropriate fit indices with AI youth, a general ideation index and an active ideation index. Scores on the active ideation and general ideation indices were also related to cumulative stress, self-reported suicidal ideation and previous suicide attempt, providing a measure of convergent validity. Finally, use of cutpoint of 20, rather than published cutpoint of 31, evidenced marginally better positive and negative predictive values, with sensitivity within acceptable ranges.

SIQ-JR在美国西南印第安部落中的因子结构和有效性。

尽管在AI社区中自杀负担不成比例，但以前的文献在评估美洲印第安人（AI）人群自杀筛查方法的心理计量学特性方面受到严重限制。本研究的目的是使用两个西南部落的AI青少年社区样本，研究AI青年自杀意念调查表（SIQ-JR）的心理测量特性。本研究样本由114位参与者（n = 91和n = 23）组成，年龄分别为10-19岁，来自2项研究，这两项研究均在尝试自杀指数后90天内给予SIQ-JR。研究结果表明，两因素模型产生了与AI青年相适应的适应指数，总体观念指数和主动观念指数。主动构想和总体构想指数的得分也与累积压力，自我报告的自杀构想和先前的自杀企图有关，从而提供了收敛效度的量度。最后，使用20的临界点，而不是31的已公布的临界点，证明阳性和阴性的预测值略高，敏感性在可接受的范围内。（PsycINFO数据库记录（c）2018 APA，保留所有权利）。
