Purpose: Recent studies demonstrated that the embodiment disorder represents a core feature of eating disorders (EDs). The aim of this study was to evaluate the role of its variation as a possible mediator of the efficacy of enhanced cognitive behavioural therapy (CBT-E) on classic ED symptomatology, including body uneasiness. Methods: 73 patients with anorexia nervosa and 68 with bulimia nervosa were treated with a multidisciplinary approach including CBT-E. Psychometric questionnaires were administered at baseline (T0) and after one (T1) and 2 years (T2) to evaluate general and ED-specific psychopathology, body uneasiness and the embodiment disorder. Data regarding diagnostic crossover and remission were also collected. Results: Longitudinal analysis showed an improvement of all psychopathological dimensions at T1, which remained stable at T2 (p < 0.05). Remission rate at T2 was 44.7%, and diagnostic crossover occurred in 17.0% of patients. Higher levels of embodiment disorder predicted increased diagnostic instability (OR: 1.80 [1.01–3.20], p = 0.045). The amelioration of the embodiment disorder mediated the decrease in both ED-specific psychopathology (indirect effect: 0.67 [0.46–0.92]) and body uneasiness (indirect effect: 0.43 [0.28–0.59]). Conclusion: For the first time, these findings highlighted the role of the embodiment disorder as a maintaining factor of ED symptomatology, supporting the importance of integrating CBT-E with a phenomenological model of EDs. Level of evidence: Level IV, longitudinal observational study (case series).

Abstract

Purpose: Recent studies demonstrated that the embodiment disorder represents a core feature of eating disorders (EDs). The aim of this study was to evaluate the role of its variation as a possible mediator of the efficacy of enhanced cognitive behavioural therapy (CBT-E) on classic ED symptomatology, including body uneasiness. Methods: 73 patients with anorexia nervosa and 68 with bulimia nervosa were treated with a multidisciplinary approach including CBT-E. Psychometric questionnaires were administered at baseline (T0) and after one (T1) and 2 years (T2) to evaluate general and ED-specific psychopathology, body uneasiness and the embodiment disorder. Data regarding diagnostic crossover and remission were also collected. Results: Longitudinal analysis showed an improvement of all psychopathological dimensions at T1, which remained stable at T2 (p < 0.05). Remission rate at T2 was 44.7%, and diagnostic crossover occurred in 17.0% of patients. Higher levels of embodiment disorder predicted increased diagnostic instability (OR: 1.80 [1.01–3.20], p = 0.045). The amelioration of the embodiment disorder mediated the decrease in both ED-specific psychopathology (indirect effect: 0.67 [0.46–0.92]) and body uneasiness (indirect effect: 0.43 [0.28–0.59]). Conclusion: For the first time, these findings highlighted the role of the embodiment disorder as a maintaining factor of ED symptomatology, supporting the importance of integrating CBT-E with a phenomenological model of EDs. Level of evidence: Level IV, longitudinal observational study (case series).
