Figure 1
Free curve slope intercept model. This figure illustrates the unstandardized parameter estimates for the orthogonal free curve slope intercept model of borderline personality disorder symptom development from age 14 to age 19. Circles indicate latent intercept and slope variables and squares indicate manifest (observed) variables. The triangle represents the intercept factor, and the loadings emanating from this variable are the intercept and slope means. Double-headed arrows (slings) represent variances and single-headed (straight) arrows are regression paths. Underlined values indicate parameter was fixed to one. The covariance between the latent intercept and slope variables is not shown because this parameter was fixed to zero. All estimated parameters are significant at p < .001 with the exception of the slope loading for BPD symptoms at age 17, which was nonsignificant (0.09, p > .05).
