Development of instrumentation for a study on relationship between integrated management system and innovation performance in Malaysia Green building industry

Abstract

A questionnaire is a vital research instrument consisting of a series of questions for the purpose of gathering information from respondents. Most psychological research required an instrument that shall be valid and reliable to investigate that particular study’s intended variables. Eventually, such an instrument that fits the study is very rare. So, a need was felt to develop a suitable and reliable tool for the same purpose. To develop an instrument for measuring variables, i.e., Integrated Management System and Innovation Performance, and to test its reliability and validity. A draft of the 59-item scale was developed, which comprises 14 items in the demographics section and 45 measurement items. The tool’s content validity was established by accepting items that range in between 75% to 90% of the validity index for each item. To test the instrument’s reliability, a pilot study was conducted where the instrument is applied to 30 respondents representing 30 different organisations involved in building construction. The instrument passes the content validity with an index of .78 while it has no significant face validity issues. Statistical analyses showed excellent internal consistency by Cronbach’s alpha which all variables are above 0.8. The instrument has acceptable properties (i.e., valid and reliable) and is suitable for measuring the intended variables, i.e., IMS and IP. It is recommended to be further tested for construct validity.
