Connecting residual depressive symptoms to self-reported executive functioning : a network analytical approach

Journal Contribution - Journal Article

Persisting executive functioning (EF) impairments following remission from depression form an important source of disability in daily life. However, little is known regarding how specific aspects of EF relate to residual depressive symptomatology. Using network analysis, the current study investigates unique associations between cognitive-, affective-, and somatic depressive symptoms (Beck Depression Inventory 2nd edition, BDI-II) and self-reported EF (Behavior Rating Inventory of Executive Function Adult version, BRIEF-A) in a sample of 161 remitted depressed individuals. We identified three clusters of closely connected nodes, corresponding with the Metacognition- and Behavioral Regulation Index of the BRIEF-A, and one cluster consisting of cognitive, affective-, and somatic depressive symptomatology. Among the clusters consisting of EF domains, working memory and shifting difficulties emerged as bridging nodes. Depressive cognition most strongly connected the cluster of depressive symptoms with the EF clusters. Depressive symptom dimensions demonstrated both shared and unique associations with EF domains. Each depressive symptom dimension was directly related to emotional control impairments. In addition, multiple associations were observed between depressive symptomatology and complaints at the level of working memory, shifting, and planning/organizing. Depressive affect was uniquely related to difficulties initiating activity. The current findings provide insights into the relationship between perceived difficulties in EF and residual depressive symptomatology. EF domains were differentially related to depressive symptom dimensions, suggesting the need for further research into the role of EF following remission from depression.
