From: Comorbidity between depression and anxiety: assessing the role of bridge mental states in dynamic psychological networks

Fig. 2

Hypothetical network of comorbid depression (DEP1–DEP3) and anxiety (ANX1 and ANX2), in which bridge mental states (i.e., momentary experiences of symptoms) (B1 and B2) funnel the activity from one mental state cluster to the other. The lines within the two mental state clusters show the within-cluster associations between the mental states. The four arrows show possible indirect effects from depression mental state 1 (DEP1) → bridge mental state 1 (B1) → anxiety mental state 1 (ANX1), and vice versa, from anxiety mental state 2 → bridge mental state 2 → depression mental state 3. The indirect effects via the bridge mental states, such as A*B in the figure, are hypothesized to be stronger in the network of individuals with comorbid depression and anxiety, as compared to individuals with either disorder
