Associations between major depressive disorder and performance-based and self-reported music cognition

Area of Science:

• Neuroscience
• Psychiatry
• Cognitive Psychology

Background:

• Major Depressive Disorder (MDD) is associated with various cognitive impairments.
• Music cognition deficits in MDD are under-researched, with prior studies relying solely on performance tests.
• This study investigates music perception and memory in MDD using both performance and self-report measures.

Purpose of the Study:

• To compare music perception and memory between individuals with MDD and a control group.
• To assess amusic dysfunction using performance-based tests and self-report questionnaires.
• To examine the relationship between performance and self-reported measures of music cognition in MDD.

Main Methods:

• Recruited 62 participants: 34 with MDD and 18 controls.
• Administered the Montreal Battery for Evaluation of Amusia (MBEA) for performance-based assessment.
• Utilized the Amusic Dysfunction Inventory (ADI) for self-reported amusic dysfunction.

Main Results:

• No significant differences were found between MDD and control groups on MBEA or ADI dimensions.
• Associations were observed between specific ADI subscales (Vocal Production, Melodic Perception) and MBEA tests (Scale, Contour, Interval, Memory).

Conclusions:

• Basic music perception and memory are not direct cognitive deficits in MDD.
• Indirect effects on music cognition may occur due to other MDD-related cognitive issues, such as reduced concentration and mental fatigue.
