The objective of the paper is to develop a validated scale to measure the factors that cause delays in infrastructure projects. The study employed a standard three phase scale development procedure of Churchill (1979) which was augmented subsequently by Nunnally, Bernstein and Berge (1994) and Prakash and Phadtare (2018). In phase one, 73 factors that cause delays were identified, which were reduced to 45 based on literature review and expert opinions. These 45 factors were subjected to an exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) in phase two and three, respectively, to refine and establish convergent, discriminant and nomological validity of the scale. The study confirms that delays in infrastructure projects happen due to six factors, i.e., Contractor Related Factors (CON); Consultant Related Factors (CS); External Factors (EX); Labour Related Factors (LR); Material Related Factors (MT) and Design Related Factors (DJ). The study is particularly useful for the firms engaged in the development of infrastructure projects globally, as it identifies and ranks the factors that cause delays in a project. However, the study being confirmatory in nature only confirms the grouping of factors causing delays and is also limited by the possibility of sampling error.

制定导致印度基础设施项目延迟的因素量表

本文的目的是开发一种经过验证的量表，以测量导致基础设施项目延迟的因素。该研究采用了丘吉尔（1979）的标准的三阶段规模开发程序，随后由纳纳利（Nunnally），伯恩斯坦（Bernstein）和贝格（Berge）（1994）以及普拉卡什（Prakash）和帕塔特（Phadtare）（2018）进行了扩充。在第一阶段，确定了导致延误的73个因素，根据文献回顾和专家意见，这些因素已减少至45个。在第2阶段和第3阶段分别对这45个因子进行探索性因子分析（EFA）和验证性因子分析（CFA），以完善和确定量表的收敛性，判别性和法理学有效性。该研究证实，基础设施项目的延误是由六个因素引起的，即承包商相关因素（CON）。顾问相关因素（CS）；外部因素（EX）；劳动相关因素（LR）；材料相关因素（MT）和设计相关因素（DJ）。这项研究对全球范围内从事基础设施项目开发的公司特别有用，因为它可以识别和排序导致项目延误的因素。但是，这项研究本质上只是确定性的，只能证实引起延误的因素的分组，并且还受到抽样误差可能性的限制。
