BPD, Borderline personality disorder; CFI, comparative fit index; TLI, Tucker—Lewis index; RMSEA, root mean square error of approximation; Loadings, factor loading estimates; S.E., factor loading standard error; Res, criterion residual variance; Null, chi-square fit for uncorrelated baseline model; χ², chi-square fit for single-factor model.

Degrees of freedom are given in parentheses. For the weighted least squares means and variance adjusted (WLSMV) estimator, degrees of freedom are estimated and data dependent.
