Table 4.

Parameter estimates, R-squared values and Standard Error for the proposed Confirmatory Factor Analysis Model and Re-specified Model. The factor loadings (standardised/unstandardized), standard errors and squared factor loadings (R-squared) for all 25 observed variables (Items) and the eight first-order factor (factor loadings). Two loading estimates representing the cross-loading for Item 22 are given for the re-specified model. The values presented in bold have poor associations with their designated factor, all below the recommended cut-off <0.40. β = Standardised parameter estimate; B = Unstandardised parameter estimate; SE = Standard Error; R2 = R-squared. TFI = Tinnitus functional Index; F1 = Intrusiveness; F2 = Sense of control; F3 = Cognition, F4 = Sleep; F5 = Auditory; F6 = Relaxation; F7 = Quality of life; F8 = Emotional.
