The role of adaptive beliefs and attitudes against suicide has not been given adequate attention in the clinical or assessment literature. This article reports on the development and initial psychometric properties of a 32-item self-report inventory, the Reasons for Living Inventory for Adolescents (RFL-A). In Phase 1, we used exploratory and confirmatory factor analyses to identify five correlated factors: Future Optimism, Suicide-Related Concerns, Family Alliance, Peer Acceptance and Support, and Self-Acceptance. In Phase 2, we cross-validated the 5-factor oblique model in a different group of adolescents recruited from two high schools. In addition, we examined evidence for convergent, discriminant, and construct validities. The coefficient alpha indices for the RFL-A total and scales were satisfactory. In Phase 3, we evaluated additional evidence of reliability and validity using samples of high school and psychiatric inpatient adolescents. The results suggest that the RFL-A is a short, reliable, and valid measure that is potentially useful in the assessment of adolescent suicidal behavior.
在临床或评估文献中，针对自杀的适应性信念和态度的作用尚未得到充分关注。本文报告了一个包含32个条目的自陈式量表——青少年生存理由量表（RFL-A）的编制过程及其初步心理测量特性。在第一阶段，我们运用探索性和验证性因素分析来确定五个相关因素：未来乐观主义、与自杀相关的担忧、家庭联盟、同伴接纳与支持以及自我接纳。在第二阶段，我们在从两所高中招募的另一组青少年中对五因素斜交模型进行了交叉验证。此外，我们还检验了聚合效度、区分效度和结构效度的证据。RFL-A总量表和分量表的α系数指标令人满意。在第三阶段，我们使用高中和精神科住院青少年样本评估了可靠性和效度的其他证据。结果表明，RFL-A是一种简短、可靠且有效的测量工具，在评估青少年自杀行为方面可能具有实用价值。
