The Will-to-Live Scale (WTLS) is used to measure the will to live in older adults; however, there is no Spanish version. The objective of the study was to translate the WTLS into Spanish, assess its internal structure, reliability, and the correlates between WTLS and life satisfaction, resilience, and depression in older Peruvian adults.
The participants were 235 Peruvian older adults (M=72.69, SD=6.68), evaluated between March to May 2019, selected through non-probability sampling. The WTLS, the Satisfaction with Life Scale (SWLS), the Brief Resilient Coping Scale (BRCS) and the Patient Health Questionnaire-2 (PHQ-2) were administered. Data analysis included reliability by internal consistency and structural equation models, specifically confirmatory factor analysis (AFC), to test the one-dimensional solution of the WTLS and the convergent validity of the WTLS at the latent level, by specifying a four-factor model (will to live, life satisfaction, resilience and depression).
Cronbach's alpha coefficient and the composite reliability index obtain values of .93 and .94, respectively. The one-dimensional structure of the WTLS was fitted to the data (χ=10,067, P=.073, CFI=.999, RMSEA=.066, SRMR=.014) and showed positive associations with the SWLS (ρ=.82), and BRCS (ρ=.86), as well as negative associations with the PHQ-2 (ρ=-.66).
The WTLS in Spanish presents evidence of validity and reliability to measure the will to live in Peruvian older adults.
生活意愿量表（WTLS）用于衡量老年人的生活意愿；然而，目前尚无西班牙语版本。本研究旨在将 WTLS 翻译为西班牙语，并评估其内部结构、信度以及 WTLS 与生活满意度、韧性和秘鲁老年人抑郁之间的相关性。
研究对象为 235 名秘鲁老年人（M=72.69，SD=6.68），于 2019 年 3 月至 5 月期间通过非概率抽样选择。采用 WTLS、生活满意度量表（SWLS）、简短韧性应对量表（BRCS）和患者健康问卷-2（PHQ-2）进行评估。数据分析包括内部一致性的信度和结构方程模型，特别是验证性因子分析（AFC），以测试 WTLS 的一维解决方案和 WTLS 在潜在水平上的收敛有效性，具体规定了四因素模型（生活意愿、生活满意度、韧性和抑郁）。
Cronbach's alpha 系数和综合可靠性指数分别获得.93 和.94 的值。WTLS 的一维结构与数据拟合良好（χ=10.067，P=.073，CFI=.999，RMSEA=.066，SRMR=.014），并与 SWLS（ρ=.82）和 BRCS（ρ=.86）呈正相关，与 PHQ-2（ρ=-.66）呈负相关。
西班牙语版的 WTLS 具有有效性和可靠性证据，可用于衡量秘鲁老年人的生活意愿。
