I would like to use this study as material for my research paper. However, the Cronbach's alpha coefficient for this study is 0.584 (p. 1489). I feel that this coefficient is too low to use as material, but do you think I can use it?
And if it is not usable, why do you think this paper was accepted?
Yes, that is too low to meet the assumption that all your variables are so highly correlated that they essentially measure the same thing. Your first step should be to examine the option for "alpha if item deleted," which will show you whether there is any single item that does fit (this will also alert you if any of your items are "reverse" coding so that they are generating negative correlations).
If that does not resolve your problem, the next step would be an exploratory factor analysis to determine whether your items actually measure two or more concepts, rather than just one.
