Item-total correlation is an extensively used method for checking the homogeneity of the scale made up of number of items. It is simply the Pearson's product moment correlation coef?cient of the individual item with the scale total computed from the remaining items. The general rule of thumb is that an item must be correlate with the total above 0.20. Items with the lower correlation
