On the basis of the self-centeredness and selflessness model, a new instrument assessing two distinct dimensions of happiness, fluctuating and authentic-durable, was developed. The current research aimed at examining the factor structure of the Italian version of the instrument, its psychometric properties and construct validity. To this end, two studies were carried out. Study 1 (N = 544) examined different measurement models, from unidimensional to multidimensional, from a fully symmetrical bifactor solution to a bifactor (S-1) solution. Findings indicated better and adequate fit indices for the last model. Using various samples (n = 1274) Study 2 confirmed the bifactor (S-1) structure and analysed psychometric properties, convergent and divergent validity and temporal stability of the instrument. Findings generally gave evidence of the multidimensional conceptualization of the construct, good levels of reliability values and adequate convergent validity of both scales. Discriminant validity showed mixed results from no association of age with authentic-durable happiness to weak and negative association with fluctuating happiness. Test-retest reliability displayed an adequate value of correlation coefficient for the two set scores of the authentic dimension and a value below the recommended cut-off criteria for the fluctuating dimension, where significant differences in the mean scores emerged. Future studies should aim to replicate the results of this research and attempt to overcome its limitations.
基于自我中心和无私的模型，开发了一种新的工具来评估幸福感的两个不同维度，即波动和真实持久。本研究旨在检验该工具的意大利版本的因素结构、心理测量学特性和构念效度。为此，进行了两项研究。研究 1（N=544）检验了不同的测量模型，从单维度到多维度，从完全对称的双因素解决方案到双因素（S-1）解决方案。研究结果表明，最后一个模型的拟合指数更好且更合适。使用不同的样本（n=1274），研究 2 证实了双因素（S-1）结构，并分析了工具的心理测量特性、收敛和发散效度以及时间稳定性。研究结果普遍证明了该构念的多维概念化、两个量表的可靠性值水平良好和收敛效度适当。区分效度显示出混合结果，即年龄与真实持久的幸福感之间没有关联，与波动的幸福感之间存在较弱和负相关。重测信度显示，真实维度的两个成套分数的相关系数具有适当的值，而波动维度的相关系数低于推荐的临界值标准，其中均值分数出现了显著差异。未来的研究应该旨在复制本研究的结果，并尝试克服其局限性。
