Note : σ_λ, standard deviation of the salient loadings obtained after rotation over the 10,000 simulations; R_%, percentage of simulations in which all the items in the scale load on the right factor; W_%, mean of percentages of items loading on the wrong factor in the scale after rotation over the 10,000 simulations ; —, < 5 × 10^–2.
