needed. In fact, replicating such findings using taxometric analyses would be ideal given that taxometric procedures and FMM are mathematically distinct, are based on different sets of assumptions, and may arrive at qualitatively different results that are not directly comparable—even when using the same data for one construct (e.g., FMM may yield a 3 group structure, whereas taxometric methods can only result in either a dimensional or a 2 group structure; Lubke and Muthén, 2005; Waller and Meehl, 1998; but see McGrath and Walters, 2012; Walters et al., 2010a for ways to integrate taxometrics with other latent modeling methods to identify polytomous constructs).
