According to Barbaranelli [56], if one item loads on two factors and the ratio between the
two loadings is lower than 2, it cannot be considered a pure marker of its primary factor, yet it can be retained if the ratio is not lower than 1.5. The ratio values for item 3 and 7 were, respectively, 1.64 and 1.55. Item 3 was therefore retained as an indicator of emotion regulation and item 7 as indicator of procedural self-efficacy. Item 11 showed a cross-loading on procedural self-efficacy, which was very close to 0.30.
