Bifactor coefficients

Factor loadings are derived from full-information maximum likelihood confirmatory bifactor analysis, equivalent to a bifactor graded response model. SP, sensory profile; SEQ, Sensory Experiences Questionnaire; h², communality; I-ECV, item explained common variance; G-SEEK, general SEEK domain factor; ω_T, coefficient omega total (total score reliability); ω_S, coefficient omega subscale (subscale reliability); ω_H, coefficient omega hierarchical (general factor saturation; ≥ 0.8 indicates strong general factor); ω_HS, coefficient omega hierarchical subscale (specific factor saturation; ≥ 0.20/0.25 support the added value of a specific factor under conditions of high/low reliability, respectively); ECV_G, general factor explained common variance; ECV_SS, specific factor explained common variance for a subscale (≥ 0.30/0.45 support the added value of a specific factor under conditions of high/low reliability, respectively)
