Associations between compulsive exercise and mental health constructs in eating disorders

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Science

Background:

• Compulsive exercise (CE) is frequently observed in individuals with eating disorders (ED).
• CE is associated with a more severe clinical presentation in ED.
• This study investigated the relationship between CE, ED symptoms, and other psychological features.

Purpose of the Study:

• To examine the associations between compulsive exercise (CE) and eating disorder (ED) symptoms.
• To explore the relationship between CE and core psychological features like obsessive-compulsive disorder (OCD) symptoms, anxiety, perfectionism, and depression.
• To understand the role of CE in the context of ED and other psychological conditions.

Main Methods:

• A cross-sectional study involving 3105 participants from the Eating Disorders Genetics Initiative-Sweden.
• Multiple linear regression analyses were used to investigate associations.
• The Compulsive Exercise Test (CET) and its subscales were used to measure CE.

Main Results:

• Eating disorder symptoms, obsessive-compulsive disorder (OCD) symptoms, and perfectionism were uniquely positively associated with compulsive exercise (CE).
• Depressive symptoms showed a unique negative association with CE when controlling for other constructs.
• Each subscale of the Compulsive Exercise Test (CET) demonstrated distinct patterns of association with the examined psychological features.

Conclusions:

• The findings align with previous research and the cognitive-behavioral model of CE.
• CE may be particularly clinically relevant when co-occurring with ED symptoms.
• Further research is needed to clarify the directionality of associations between OCD symptoms, perfectionism, and CE, especially in non-ED populations.
