Many studies investigating age-related mean differences in life satisfaction disregard potential differences in the structure of the life satisfaction construct. Because developmental tasks at different life stages vary and thus the salience of specific life domains (e.g., health, finances, relationships, etc.) might differ, life satisfaction might differ between age groups in its underlying structure and meaning.

美国成人样本中不同年龄的生活满意度的结构性差异

许多调查生活满意度与年龄相关的平均差异的研究忽视了生活满意度结构的潜在差异。由于不同生命阶段的发展任务不同，因此特定生活领域（例如，健康、财务、人际关系等）的重要性可能不同，因此不同年龄组的生活满意度可能在其基本结构和意义方面有所不同。
