Design and Implementation of Content Validity: Instrument Development for Evaluating Functional Building Performance

The research aim is to critically evaluate the content validity of the functional building performance evaluation criteria using the Content Validity Index (CVI) and modified kappa statistic. The selection of relevant criteria for functional building performance evaluation should be managed effectively by the building management team because it is strongly related to the achievement of organizational objectives and the building occupants’ satisfaction. Studies over the past decades have shown that the criteria vary, relying on the intention of conducting the performance evaluation and the types of building. These selection criteria have a direct impact on the functional building performance and need to be done systematically. Thus, the content validity of the functional building performance evaluation criteria is a necessary step in instrument development. To achieve this research aim, the instrument has been developed based on numerous construct items that have been obtained from previous studies by various authors and established rating tools or standards. The sample of the respondents for content validation comprises of seven (7) expert panels in the area of historic building management and building performance evaluation, such as from the local municipality, related government agencies, academician and building management team. The panels reviewed and rated the instrument to ensure its relevance and the representativeness of each item. The result shows that a total of 39 items are valid and are considered to be retained, and will be further tested in the next study. The result has also shown that the Scale level – CVI/ Averaging calculation method (S-CVI/ Ave) for all items has met the criterion of 0.90. Significantly, content validity should be treated as important because it provides adequate and acceptable items of the content domain
