BACKGROUND: Recent research highlights the central role of emotion in psychopathology, with Panksepp's Affective Neuroscience Theory identifying seven primary emotional systems critical for mammalian survival. Although this framework has advanced understanding of disorders such as depression and addiction, its application to eating pathology remains limited.
OBJECTIVE: The present study integrates affective neuroscience with behavioural analysis, conceptualizing emotions not merely as neural activations but as classes of behaviour shaped by phylogenetic selection and ontogenetic contingencies.
METHODS: Eating disorders, characterized by maladaptive eating patterns that impair physical and psychological functioning, are examined here as emotional-behavioural phenomena maintained by reinforcement processes. This cross-sectional, correlational study investigated associations between emotional systems and disordered eating.
RESULTS: Weak but statistically significant correlations were found between negative emotional systems (FEAR, PANIC/GRIEF, RAGE) and disordered eating (r ≈ .15-.25, 95% CI [.07, .35]), suggesting that difficulties in emotion regulation may act as antecedents and reinforcers of maladaptive coping behaviours. Positive emotional systems (PLAY, CARE, SEEKING) showed no significant relationships, indicating heterogeneous reward contingencies among individuals with eating pathology. Exploratory gender-stratified analyses revealed small differences in emotional correlates but no moderation effects, underscoring similar functional mechanisms across sexes.
CONCLUSIONS: Findings are interpreted within a functional-analytic framework, proposing that disordered eating is maintained by negative reinforcement, reducing aversive private events such as shame, fear, or panic. Clinically, results highlight the need for integrated, context-sensitive interventions that target emotion regulation and avoidance mechanisms across genders.
