The present study sought to determine if dispositional optimism/pessimism and facets of the tripartite model of meaning in life (viz., comprehension, purpose, & mattering) represent important and additive prospective predictors of subsequent well-being (assessed 3 months later) in 166 adults. Results from hierarchical regression analyses indicated that the presence of optimism, but not the absence of pessimism, consistently predicted subsequent positive affect, life satisfaction, and subjective happiness. Moreover, beyond the variance accounted for by future expectancies, comprehension was found to predict life satisfaction, whereas purpose was found to predict positive affect. Mattering was found to predict subjective happiness and, to a weaker extent, positive affect. Overall, these findings not only indicate that the presence of optimism is important for experiencing future well-being in adults, but they go further to clarify which specific facets of meaning in life also play an important additive role in contributing to future well-being in adults.

本研究试图确定性格乐观/悲观和生活意义三重模型的各个方面（即理解、目的和重要性）是否代表了随后幸福感（3个月后评估）的重要和附加的前瞻性预测因素。 166 名成人。层次回归分析的结果表明，乐观情绪的存在，而不是悲观情绪的缺失，一致地预测了随后的积极情绪、生活满意度和主观幸福感。此外，除了未来预期所造成的差异之外，理解力还可以预测生活满意度，而目的性则可以预测积极的影响。研究发现，重要性可以预测主观幸福感，并在较弱的程度上预测积极情绪。总的来说，这些发现不仅表明乐观情绪对于成年人未来的幸福感很重要，而且还进一步阐明了生活意义的哪些具体方面在促进成年人未来幸福感方面也发挥着重要的附加作用。成年人。
