For the current study, IIP octant scores were standardized based on the respective national
norms. Internal consistencies were adequate to high (Cronbach’s alpha = .93 for the total score;
octant scales between .701 and .873). Moreover, the CircE fit indices (Grassi, Luccio, & Di Blas,
2010) showed an excellent fit to a circumplex model with equal spacing and equal communality
(comparative fit index [CFI] = .962, Tucker-Lewis index [TLI] = .956, root mean square error
of approximation [RMSEA] = .087)
