Krug I, Dang AB, Hughes EK. There is nothing as inconsistent as the OSFED diagnostic criteria. Trends Mol Med 2024; 30:403-415.

Abstract
Atypical anorexia nervosa (AAN), purging disorder (PD), night eating syndrome (NES), and subthreshold bulimia nervosa and binge-eating disorder (Sub-BN/BED) are the five categories that comprise the 'Other Specified Feeding or Eating Disorder' (OSFED) category in the Diagnostic and Statistical Manual for Mental Disorders (DSM-5). In this review, we examine problems with the diagnostic criteria that are currently proposed for the five OSFED types. We conclude that the existing diagnostic criteria for OSFED are deficient and fall short of accurately describing the complexity and individuality of those with these eating disorders (EDs). Therefore, to enhance the quality of life of people with OSFED, diagnostic criteria for the condition should be applied uniformly in clinical and research settings.

Horvath SA, Keel PK, Forney KJ. Examining negative urgency as a predictor of eating disorder maintenance in purging syndromes. J Clin Psychol 2024. [PMID: 38554059 DOI: 10.1002/jclp.23683] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Revised: 12/21/2023] [Accepted: 03/20/2024] [Indexed: 04/01/2024]
Abstract
OBJECTIVES Negative urgency is associated with short-term maintenance of binge eating and purging in unselected samples. The current study used an eating disorder sample to test the hypothesis that negative urgency maintains bulimia nervosa (BN) and purging disorder (PD) at long-term follow-up. It was also hypothesized that baseline differences in negative urgency between BN and PD would remain at follow-up. METHODS Secondary analyses were conducted on a sample of women who engaged in recurrent self-induced vomiting (n = 68; 52.9% BN; 47.1% PD). Women completed diagnostic interviews and questionnaires at baseline and at a mean (SD) of 5.95 (1.58) years follow-up (range = 2.51-9.62; retention rate = 75%). RESULTS Negative urgency did not predict eating disorder diagnostic status, recovery status, or global eating pathology at follow-up (p's = .06-.83). There were no significant differences in negative urgency across women with BN and PD at follow-up (p = .16). However, post hoc analyses indicated that negative urgency was not stable across time (ICC = .102). Increases in negative urgency from baseline to follow-up were associated with greater global eating pathology at follow-up (p = .002). CONCLUSION Results suggest negative urgency does not predict long-term eating disorder maintenance. Negative urgency may not be a stable personality trait but rather an indicator of overall poor emotion regulation. Future research should confirm that changes in negative urgency predict chronic eating pathology over long durations of follow-up in women who have increasing negative urgency across time.

[PMID: 37887447 PMCID: PMC10603863 DOI: 10.3390/bs13100797] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/17/2023] [Accepted: 09/20/2023] [Indexed: 10/28/2023] Open
Abstract
(1) Background: Bariatric surgery (BS) is highly effective for treating severe obesity in the long term. However, studies investigating predictors and personality profiles linked to BS success yield inconsistent results due to varying methodologies and limited research. This paper aims to identify personality profiles associated with BS success. (2) Method: The study involved 67 patients undergoing bariatric surgery, evaluated through clinical and personality measures. Weight loss was monitored at 6, 12, and 24 months post-surgery. Hierarchical case cluster analysis and iterative k-means cluster analysis identified distinct groups based on excess body mass index loss (%EBL) at these intervals. ANOVA was employed to compare personality profiles between groups. (3) Results: Average weight loss after 24 months was 67.2%. Two success profiles emerged: 46.5% showed very good success, achieving 90% EBL in 24 months, while 55% in the second cluster had less than 40% EBL throughout follow-up. The successful profile correlated with greater self-efficacy and improved emotional adjustment. (4) Conclusions: Successful BS outcomes were linked to personality traits promoting sustained weight loss post-surgery.

Krug I, Giles SE, Granero R, Agüera Z, Sánchez I, Sánchez-Gonzalez J, Jimenez-Murcia S, Fernandez-Aranda F. Where does purging disorder lie on the symptomatologic and personality continuum when compared to other eating disorder subtypes? Implications for the DSM. EUROPEAN EATING DISORDERS REVIEW 2021; 30:36-49. [PMID: 34825434 DOI: 10.1002/erv.2872] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2021] [Revised: 09/07/2021] [Accepted: 10/26/2021] [Indexed: 12/28/2022]
Abstract
OBJECTIVES To assess the clinical significance and distinctiveness of purging disorder (PD) from other eating disorder (ED) diagnoses. METHOD Participants included 3127 women consecutively admitted to an ED treatment centre (246 PD, 465 anorexia nervosa restrictive [AN-R], 327 AN-binge purging [AN-BP], 1436 bulimia nervosa [BN], 360 binge eating disorder [BED], 177 atypical AN and 116 unspecified feeding or eating disorder [UFED]) who were diagnosed according to DSM-5 criteria. Additionally, 822 control participants were recruited from the community. All participants completed measures assessing ED symptoms (EDI-2), general psychopathology (SCL-90-R) and personality (TCI-R). RESULTS Patients with PD, when compared to controls, scored significantly higher on the EDI-2 and SCL-90-R, and most TCI-R dimensions. Most of the significant differences between PD and the other ED diagnoses emerged between PD and AN-R, followed by Atypical-AN, UFED, AN-BP and BED, with patients with PD typically reporting higher scores on the EDI-2 and SCL-90-R subscales. Significant differences between PD and BN were also present, but to a lesser extent. The findings for personality varied amongst the different ED diagnoses. CONCLUSIONS PD is a clinically significant disorder, which seems to be more similar to BN than it is to AN and the other ED subtypes.
