MBCT = Mindfulness-based Cognitive Behavioral Therapy; CONTROL = waitlist control condition.
Figure 2.
Mediation analysis pathway, for the effect of MBCT on residual symptoms of depression.
N.B. All variables are change scores over time. The numbers show the four different levels of analyses.
Figure 3.
Graphical display of the resulting significant mediations for the total group and the two subgroups (≤2 MDE & ≥3MDE).
A Mediating mechanisms MBCT for total group. B Mediating mechanisms MBCT for subgroup two or less depressions. C Mediating mechanisms MBCT for subgroup three or more depressions. The numbers in the figure show the percentage of mediation (indirect effect) of that mediator on the next phenotype. The figure can be conceived as consisting of mediation-triangles, where on top of the triangle the percentage of mediation is shown. For example in Figure 2a, the effect of MBCT on IDS-SR30 is mediated for 51% by PSWQ (and the effect of PSWQ on IDS-SR30, is again mediated by PA & NA). Also, the effect of MBCT on PSWQ is for 48% mediated by KIMS. The reported mediations do not account for a unique effect, but overlap with each other, reflecting a series of separate regressions (one for each triangle).
