Thank you. The full reference is: Hülsheger, U. R., Lang, J. W., Depenbrock, F., Fehrmann, C., Zijlstra, F. R., & Alberts, H. J. (2014). The power of presence: The role of mindfulness at work for daily levels and change trajectories of psychological detachment and sleep quality. Journal of Applied Psychology, 99(6), 1113-1128. The relevant paragraph is on page 1119: "Yet, as outlined in the introduction, we were not only interested in independent effects at both levels of analysis but also in whether effects differ significantly between levels of analysis. The question was thus whether an emergent effect exists (Chen et al., 2005; Enders & Tofighi, 2007; Lüdtke et al., 2008), for instance, if the mindfulness–psychological detachment relationship is stronger at the between-person than at the within-person level of analysis. To test for emergent effects, we used the approach described by Muthen and Muthen (1998 –2012, pp. 262–263; also see Ludtke et al., 2008). In doing so, we estimated additional values indicating the differences between the Level 1 and Level 2 effects (aw vs. ab, bw vs. bb, and cw vs. cb; see Figure 1)."
Yes, you can use Satorra- Bentler difference testing but perhaps a simpler approach is to label the a, b, c parameters in the Model command and then use Model Constraint to test their differences. E.g.
