Supplementary Materials for the Study "Effects of Digital Leadership on Construction Project Performance: A Mixed Methods Study"

This dataset comprises the supplementary materials associated with the research paper titled "Effects of Digital Leadership on Construction Project Performance: A Mixed Methods Study." It provides detailed documentation supporting the methodology, measurement instruments, and analytical procedures employed in the study. The supplementary materials include: Appendix A: Construct Measurement Indicators, Validity, and Reliability: Presents the measurement items, factor loadings, average variance extracted (AVE), composite reliability (CR), Cronbach's alpha coefficients, Kaiser-Meyer-Olkin (KMO) values, and cumulative variance explained for each of the five core constructs examined in the study: Digital Leadership, Thriving at Work, Ambidextrous Capability, Environmental Dynamics, and Project Performance. Literature sources for each scale are also indicated. Appendix B: Semi-Structured Interview Protocol: Contains the interview guide used in the qualitative phase of the mixed-methods study. The protocol includes seven open-ended questions designed to explore participants' perceptions of digital leadership, its influence on employee thriving and organizational ambidexterity, its impact on project performance, and the role of environmental dynamism. Appendix C: Rotated Factor Matrix from Exploratory Factor Analysis: Provides the full results of the exploratory factor analysis (EFA), including factor loadings for all 19 measurement items across the five extracted factors, along with the explained variance and cumulative variance contributions. Appendix D: Discriminant Validity Analysis: Displays the discriminant validity assessment results, presenting the square root of the average variance extracted (AVE) for each construct (on the diagonal) alongside the inter-construct correlations. Appendix E: Comparative Model Fit Indices in Confirmatory Factor Analysis: Compares the goodness-of-fit indices for the hypothesized five-factor measurement model against several alternative nested models, supporting the structural validity and robustness of the measurement model. References: Lists the full citations for all literature sources referenced in the supplementary materials. This dataset is essential for replicating the study’s analytical procedures, validating the measurement model, and understanding the methodological rigor underlying the findings of the research on digital leadership in construction project management. The materials are provided in a structured format to facilitate transparency, reproducibility, and further scholarly inquiry.本数据集收录于题为《数字领导力对建筑工程项目绩效的影响：一项混合方法研究》的学术论文配套补充材料，旨在为该研究采用的研究方法、测量工具与分析流程提供详尽的佐证文档。补充材料具体包含以下内容： 附录A 构念测量指标、效度与信度：呈现本研究所考察的五大核心构念——数字领导力（Digital Leadership）、工作繁荣（Thriving at Work）、双元能力（Ambidextrous Capability）、环境动态性（Environmental Dynamics）与工程项目绩效（Project Performance）——的测量题项、因子载荷、平均变异数抽取量（Average Variance Extracted, AVE）、组合信度（Composite Reliability, CR）、克朗巴赫α系数、凯泽-迈耶-奥尔金（Kaiser-Meyer-Olkin, KMO）值以及累积解释变异量，同时标注各量表的文献来源。 附录B 半结构化访谈提纲：收录本混合方法研究质性阶段所使用的访谈指南。该提纲包含7道开放式问题，旨在探究参与者对数字领导力的认知、其对员工工作繁荣与组织双元性的影响、其对工程项目绩效的作用，以及环境动态性所扮演的角色。 附录C 探索性因子分析旋转因子矩阵：提供探索性因子分析（Exploratory Factor Analysis, EFA）的完整结果，涵盖5个提取因子下全部19个测量题项的因子载荷，以及各因子的解释变异量与累积变异贡献度。 附录D 区分效度分析：展示区分效度评估结果，呈现各构念的平均变异数抽取量平方根（对角线上数值）与构念间相关系数。 附录E 验证性因子分析的比较模型拟合指数：对比假设的五因子测量模型与多款替代性嵌套模型的拟合优度指数，佐证该测量模型的结构效度与稳健性。 参考文献：列出补充材料中引用的全部文献的完整著录信息。 本数据集对于复现该研究的分析流程、验证测量模型，以及理解建筑工程项目管理领域数字领导力相关研究发现的方法论严谨性至关重要。所有材料均采用结构化格式呈现，以提升研究透明度、可重复性，并助力后续学术探索。
