This study developed a Japanese version of the Valuation of Life (VOL) scale, to measure psychological wellbeing among older adults. In Analysis 1, we conducted a factor analysis of 13 items, and identified two factors: positive VOL and spiritual well-being. These factors had adequate degrees of internal consistency, and were related to positive mental health. In Analysis 2, we examined sociodemographic, social, and health predictors for VOL. The role of social factors was stronger than the role of health factors, and spiritual well-being was more related to moral or religious activities than positive VOL. These results suggest that predictors for VOL vary by culture. In Analysis 3, we investigated the relationship between VOL and desired years of life. Positive VOL significantly predicted more desired years of life, whereas spiritual well-being did not. Positive VOL had acceptable reliability and validity. Future research is required to investigate whether VOL predicts survival duration or end-of-life decisions.
本研究开发了日语版的生命价值（VOL）量表，用于测量老年人的心理健康状况。在分析1中，我们对13个项目进行了因子分析，确定了两个因子：积极的生命价值和精神幸福感。这些因子具有足够的内部一致性程度，并且与积极的心理健康相关。在分析2中，我们研究了生命价值的社会人口学、社会和健康预测因素。社会因素的作用比健康因素的作用更强，并且精神幸福感与道德或宗教活动的关联比积极的生命价值更强。这些结果表明，生命价值的预测因素因文化而异。在分析3中，我们研究了生命价值与期望寿命之间的关系。积极的生命价值显著预测了更长的期望寿命，而精神幸福感则不然。积极的生命价值具有可接受的信度和效度。未来需要进行研究，以调查生命价值是否能预测生存时长或临终决策。
