Four studies were conducted on the development and validation of the Measure of Sexual Identity Exploration and Commitment (MoSIEC). Exploratory factor analysis of an initial item pool yielded a 22-item measure with 4 distinct factors assessing commitment, exploration, sexual orientation identity uncertainty, and synthesis/integration. Exploratory factor analysis findings support the argument that sexual identity is a broad, multidimensional construct and that the MoSIEC assesses the construct of sexual identity in a manner consistent with J. E. Marcia's (1966) model of identity development. Confirmatory factor analyses demonstrated the stability of the MoSIEC factor structure, providing evidence of construct validity. Test-retest stability, internal consistency, and validity coefficients supported the use and continued development of the MoSIEC. Significant differences in levels of exploration and sexual orientation identity uncertainty were found among different sexual orientation identity groups, establishing the criterion-related validity of the MoSIEC. Implications for further development and use of the MoSIEC are discussed.
针对性取向认同探索与承诺量表（MoSIEC）的开发与验证进行了四项研究。对初始项目池进行探索性因素分析，得出了一个包含22个项目的量表，该量表有4个不同的因素，用于评估承诺、探索、性取向认同不确定性以及整合/综合。探索性因素分析结果支持了这样一种观点，即性取向认同是一个广泛的、多维度的结构，并且MoSIEC以与J. E. 马西亚（1966年）的认同发展模型相一致的方式评估性取向认同结构。验证性因素分析证明了MoSIEC因素结构的稳定性，提供了结构效度的证据。重测稳定性、内部一致性和效度系数支持了MoSIEC的使用和持续开发。在不同性取向认同群体之间发现了探索水平和性取向认同不确定性的显著差异，确立了MoSIEC的效标关联效度。文中讨论了MoSIEC进一步开发和使用的意义。
