Item loading for components extracted by factor analysis of LOAD, based on varimax rotated solution.

“Factor loading” is the correlation between the item and factor. Loading values>0.4 indicate good correlation of the item with the factor [31]. “Communality” represents the proportion of the variance for the item that is explained by the factor. A communality value <0.40 may indicate that the item is not related to the other items in that factor [31].
