Goodness-of-fit statistics from single cohorts (MA, OA) and multi-group (MA+OA) SEMs assessing the ASRS factor structure.

Abstract

<p>MA: middle-age cohort; OA: older-age cohort; FL: Factor loadings of ASRS items on <i>Inatt</i> and <i>Hyperact</i> latent factors; FV: Factor variance for <i>Inatt</i> and <i>Hyperact</i>; FC: Covariance between <i>Inatt</i> and <i>Hyperact</i>; V_Inatt: Variance of <i>Inatt</i>; V_Hyperact: Variance of <i>Hyperact</i>; RV: Residual Variance of ASRS items.</p><p>RMSEA: root-mean square error of approximation (optimal value <0.05); AGFI: adjusted goodness of fit index (optimal value >0.9); CFI: comparative fit index (optimal value >0.9); AIC: Akaike information criterion; BCC: Browne-Cudeck criterion. Models with the lowest values for AIC and BCC are considered to have the best fit to the data.</p>a<p>compared to Model 1;</p>b<p>compared to Model 2;</p>c<p>compared to Model 4.</p
