Identifying Affective Patterns in Patients With Eating Disorders: A Latent Profile Analysis

Area of Science:

• Psychiatry and Psychology
• Affective Neuroscience
• Clinical Psychology

Background:

• Emotional difficulties are prevalent in individuals with Eating Disorders (EDs).
• Panksepp's model posits primary emotional systems as foundational to personality.
• This study investigates emotional system profiles in an ED clinical sample.

Purpose of the Study:

• To identify distinct primary emotional system profiles in patients with EDs.
• To examine sociodemographic, clinical, and psychopathological differences across these profiles.
• To explore associations between clinical features and profile membership.

Main Methods:

• Cross-sectional study utilizing data from the Regional Centre for ED registry.
• Inclusion of measures such as Affective Neuroscience Personality scales and ED Examination.
• Application of Latent Profile Analysis followed by inferential statistical analyses.

Main Results:

• Three distinct emotional profiles emerged from 122 patients.
• Profiles characterized by varying levels of primary emotional systems (FEAR, SADNESS, SEEKING, PLAY, CARE, ANGER).
• Significant differences in age, sex, illness duration, trauma, depressive-anxiety symptoms, and ED severity were observed across profiles.

Conclusions:

• Evidence of significant emotional heterogeneity among individuals with EDs.
• Highlights the necessity of tailoring treatment plans to individual emotional profiles.
• Suggests future research directions and acknowledges study limitations.
