Note. The investigated regression models are displayed in the columns and the investigated dependent variables are displayed in the rows. The results of all other reliabilities and sample sizes (with reliability scores .60, .70, .80, and .90, and sample sizes of n = 50, 100, 150, 200, 250, 300, 400, 500) are displayed in the Supplementary Material Tables 1–32
