Abstract

Objective: The study aims at finding out the effect of reliability and validity for the compulsive buying behavior scale by Valence, d' Astou's and Fortier Scale without middle point. Methodology: Responses across 5 to 9 point scales are obtained to calculate the reliability and validity of compulsive buying behavior scale by Valence, d' Astou's and Fortier Scale. Cronbach's alpha is used to measure the internal reliability of the scale. To compare the reliability coefficients among different scale points Feldt test and Hakstian-Whalen test are used. Convergent validity for measuring inter-correlations between scales with different numbers of response categories is used and Fisher's r to z transformation is used to test population correlation coefficient. Conclusion: From study it is concluded that there is no change in reliability and validity when the middle point is dropped from the compulsive buying scale.
