F1 = Factor 1, F2 = Factor 2, Gen = Overall Score, S1 = Look and Feel of Teeth/Ease of Brushing, S2 = Brushing Experience. Items 1, 2, 16, and 17 were not included in the final factor solution and should be analyzed separately from the aggregate scores. Model fit indices: RMSEA = root mean square error of approximation (adequate fit < 0.08); CFI = Confirmatory Fit Index (adequate fit ≥ 0.95); TLI = Tucker-Lewis index (adequate fit ≥ 0.95)
