The use of measuring instruments in any scientific research is one of the most critical methodological steps. This step is of such importance that it determines the efficiency and effectiveness of the research as a whole. It must guarantee their validity and loyalty, not subjecting them to the requirements of psychometric is simply exposing the results of research to be null. Validity and reliability are two procedures in testing, measuring instrument design. Cronbachâ€™s coefficient alpha is probably the most frequently reported measure of reliability and most certainly the most abused one. Concerning reliability, Cronbach alpha weaknesses were examined, and some recommended alternatives method for assessing reliability such as stratified alpha, and composite reliability (construct reliability or Rho) were considered.
