“…First, as regards to the factor structure, it was confirmed that the data produced good fit for both 13-item three-factor (Cooke & Michie, 2001) and 18-item four-factor models (Hare, 2003; with correlated latent factors, as well as the hierarchical four-factor model. Prior research has also found that data from juvenile justice samples fit adequately both with three-factor (e.g., Hillege et al, 2011;Pechorro et al, 2014;Sevecke et al, 2009) and four factor models (e.g., Neumann et al, 2006;Sabatello et al, 2020;Salekin, 2006). These results are to some extent expected if one considers that both models are quite similar, with the four-factor model representing an extension of the three-factor model with the inclusion of the Antisocial factor (persistent and varied rule breaking).…”
