ABSTRACT
The Built Environment (BE) researchers who employ survey research design must ensure that the questionnaires designed for data collection can consistently produce comparable results when used repeatedly to be reliable. BE researchers can select among different attributes of reliability in research depending on different factors such as who, the occasion and condition under which questionnaire surveys are carried out to evaluate reliability in BE research process. This chapter presents three attributes of reliability comprising internal consistency, stability and salience. Also, the practical application of different reliability methods under each attribute is demonstrated using examples from published research. BE researchers can gain the understanding of appropriate reliability methods to use in survey research as well as the practical steps to follow in this chapter.
