A main protective factor against suicide in young adults is their reasons for living; therefore, suicide risk screening should consider these reasons. However, few psychometric instruments assess reasons for living, and none have been adapted for young adults in Portugal. Thus, we assess the psychometric characteristics of the Reasons for Living Inventory for Young Adults-II (RFL-YA-II) in participants (n = 936; Mage = 21.77; SD = 2.88) from Portugal. Participants answered measures concerning suicidal ideation, depression, hopelessness, and positive and negative affect. The results of an exploratory factorial analysis replicated the original 4-factor model of the RFL-YA-II, and a confirmatory factorial analysis indicated satisfactory indices. In terms of reliability and convergent, discriminant, and concurrent validity, our results are consistent with previous research. Moreover, our results indicate that the RFL-YA-II is a valid and reliable instrument to study the protective factors against suicidal behavior in Portuguese young adults, and should thus be integrated into preventive strategies.

年轻人生活清单的原因：葡萄牙样本中的心理计量学特性

年轻人自杀的主要保护因素是他们的生活理由；因此，自杀风险筛查应考虑这些原因。但是，很少有心理测评工具能够评估生活原因，在葡萄牙，还没有一种适用于年轻人的心理测验工具。因此，我们评估了来自葡萄牙的参与者（n = 936；法师= 21.77； SD = 2.88）中年轻人（II）的生活水平调查原因（RFL-YA-II）的心理计量学特征。参与者回答了有关自杀意念，抑郁，绝望以及正面和负面影响的措施。探索性阶乘分析的结果复制了RFL-YA-II的原始4因子模型，而确认性阶乘分析表明了令人满意的指标。在可靠性和收敛性，判别性和并发有效性方面，我们的结果与以前的研究一致。此外，我们的结果表明，RFL-YA-II是研究葡萄牙年轻人自杀行为的保护因素的有效且可靠的工具，因此应纳入预防策略。
