Introduction: Understanding and effectively treating eating disorders requires clarifying the mechanisms that maintain their symptoms. Previous studies have highlighted associations between eating disorder symptoms, emotion dysregulation and sleep quality; however, evidence addressing these three variables jointly remains scarce. Aim and method: This cross-sectional study investigated the mediating role of emotion dysregulation in the relationship between perceived sleep quality and eating disorder symptoms. The sample consisted of patients with eating disorders receiving treatment at specialized regional centers in two Italian cities. The self-report measures included were the Sleep subscale of the SCL-90-R, the DERS (total score and subscales), and the core subscales of the EDI-3. Mediation analyses were conducted using PROCESS Macro (model 4). Results: Sleep quality was significantly correlated with the DERS total score and all its subscales. Global emotion dysregulation - particularly the Non-acceptance dimension - was associated with Body Dissatisfaction and Drive for Thinness, but not with Bulimia. The relationship between sleep quality and the two cognitive eating symptoms was fully mediated by global emotion dysregulation, specifically by the Non-acceptance dimension. The total effect of sleep was significant only for Drive for Thinness. Discussion: Sleep may contribute to the maintenance of cognitive symptoms of eating disorders by exacerbating experiential avoidance, a known maintaining factor of core symptoms. Further research is needed, and sleep-related issues should be systematically addressed in the assessment and treatment of eating disorders.
Introduzione: Per comprendere e trattare efficacemente i disturbi alimentari è fondamentale chiarire i meccanismi che ne mantengono i sintomi. Studi precedenti hanno evidenziato relazioni tra sintomi alimentari, disregolazione emotiva e qualità del sonno, ma le evidenze che le considerano congiuntamente sono ancora scarse. Obiettivo e metodo: Con un disegno trasversale è stato indagato il ruolo di mediazione della regolazione emotiva nella relazione tra qualità del sonno percepita e sintomi alimentari. Il campione è composto da pazienti con disturbi alimentari afferiti ai relativi centri regionali di due città italiane. Sono state utilizzate la sottoscala Sonno della SCL-90-R, la DERS (punteggio totale e sottoscale) e le sottoscale centrali dell’EDI-3. Le analisi di mediazione sono state condotte con la PROCESS Macro (model 4). Risultati: La qualità del sonno è risultata significativamente correlata con il punteggio totale e tutte le sottoscale della DERS. La disregolazione emotiva generale - e in particolare la dimensione Mancanza di accettazione – si è associata con Insoddisfazione corporea e Spinta alla magrezza, ma non con Bulimia. La relazione tra qualità del sonno e i due sintomi alimentari cognitivi è risultata totalmente mediata dalla disregolazione emotiva generale, in particolare dalla dimensione Mancanza di accettazione. L’effetto totale del sonno è stato significativo solo per Spinta alla magrezza. Discussione: Il sonno potrebbe contribuire al mantenimento dei sintomi cognitivi dei disturbi alimentari esacerbando l’evitamento esperienziale, noto fattore di mantenimento dei sintomi. È importante condurre ulteriori studi ed includere sistematicamente l’area del sonno nella valutazione e trattamento di questi disturbi.
