Characteristics associated with the discrepancy between subjective and objective executive functioning in depression.

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Major depressive disorder (MDD) is linked to self-reported cognitive issues and objective neurocognitive deficits.
• A significant gap often exists between how individuals with MDD perceive their cognitive abilities and their actual performance on cognitive tests.

Purpose of the Study:

• To examine the relationship between subjective and objective measures of executive functions (EFs) in individuals with MDD.
• To identify factors contributing to the discrepancies between perceived and actual EF performance in MDD.

Main Methods:

• A cross-sectional study involving 62 participants with mild to moderate MDD and self-reported EF complaints.
• Objective EFs were assessed using six neurocognitive measures, forming a composite score.
• Subjective EFs were measured using the Behavior Rating Inventory of Executive Function-Adult version.

Main Results:

• Participants reported significant EF difficulties, yet most performed within the normal range on objective EF assessments.
• A weak correlation (r_s = .015) was found between subjective and objective EF measures.
• Higher levels of rumination and higher IQ scores were associated with a greater underestimation of objective EF performance.

Conclusions:

• Subjective and objective measures of EFs show minimal overlap in individuals with MDD.
• Clinical assessments of EFs in depression should incorporate both subjective and objective evaluations.
• Interventions targeting rumination may help mitigate the underestimation of cognitive deficits in MDD.
