[PMID: 36650575 PMCID: PMC9847028 DOI: 10.1186/s40337-022-00728-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 12/25/2022] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND The prevention and treatment of eating disorders relies on an extensive body of research that includes various foci and methodologies. This scoping review identified relevant studies of eating disorders, body image, and disordered eating with New Zealand samples; charted the methodologies, sample characteristics, and findings reported; and identified several gaps that should be addressed by further research. METHODS Using scoping review methodology, two databases were searched for studies examining eating disorders, disordered eating, or body image with New Zealand samples. Snowball methods were further used to identify additional relevant articles that did not appear in initial searches. Two independent reviewers screened the titles and abstracts of 473 records. Full text assessment of the remaining 251 records resulted in 148 peer-reviewed articles being identified as eligible for the final review. A search of institutional databases yielded 106 Masters and Doctoral theses for assessment, with a total of 47 theses being identified as eligible for the final review. The included studies were classified by methodology, and the extracted information included the study foci, data collected, sample size, demographic information, and key findings. RESULTS The eligible studies examined a variety of eating disorder categories including binge-eating disorder, bulimia nervosa, and anorexia nervosa, in addition to disordered eating behaviours and body image in nonclinical or community samples. Methodologies included treatment trials, secondary analysis of existing datasets, non-treatment experimental interventions, cross-sectional observation, case-control studies, qualitative and mixed-methods studies, and case studies or series. Across all of the studies, questionnaire and interview data were most commonly utilised. A wide range of sample sizes were evident, and studies often reported all-female or mostly-female participants, with minimal inclusion of males and gender minorities. There was also an underrepresentation of minority ethnicities in many studies, highlighting the need for future research to increase diversity within samples. CONCLUSION This study provides a comprehensive and detailed overview of research into eating disorders and body image in New Zealand, while highlighting important considerations for both local and international research.

[PMID: 36064606 PMCID: PMC9442924 DOI: 10.1186/s40337-022-00654-2] [Citation(s) in RCA: 55] [Impact Index Per Article: 27.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 08/15/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Eating disorders (EDs) are potentially severe, complex, and life-threatening illnesses. The mortality rate of EDs is significantly elevated compared to other psychiatric conditions, primarily due to medical complications and suicide. The current rapid review aimed to summarise the literature and identify gaps in knowledge relating to any psychiatric and medical comorbidities of eating disorders. METHODS This paper forms part of a rapid review) series scoping the evidence base for the field of EDs, conducted to inform the Australian National Eating Disorders Research and Translation Strategy 2021-2031, funded and released by the Australian Government. ScienceDirect, PubMed and Ovid/Medline were searched for English-language studies focused on the psychiatric and medical comorbidities of EDs, published between 2009 and 2021. High-level evidence such as meta-analyses, large population studies and Randomised Control Trials were prioritised. RESULTS A total of 202 studies were included in this review, with 58% pertaining to psychiatric comorbidities and 42% to medical comorbidities. For EDs in general, the most prevalent psychiatric comorbidities were anxiety (up to 62%), mood (up to 54%) and substance use and post-traumatic stress disorders (similar comorbidity rates up to 27%). The review also noted associations between specific EDs and non-suicidal self-injury, personality disorders, and neurodevelopmental disorders. EDs were complicated by medical comorbidities across the neuroendocrine, skeletal, nutritional, gastrointestinal, dental, and reproductive systems. Medical comorbidities can precede, occur alongside or emerge as a complication of the ED. CONCLUSIONS This review provides a thorough overview of the comorbid psychiatric and medical conditions co-occurring with EDs. High psychiatric and medical comorbidity rates were observed in people with EDs, with comorbidities contributing to increased ED symptom severity, maintenance of some ED behaviours, and poorer functioning as well as treatment outcomes. Early identification and management of psychiatric and medical comorbidities in people with an ED may improve response to treatment and overall outcomes.

Fumagalli G, Margola D. Is personality the key in cognitive-behavioural therapy for eating disorders? A review. Clin Psychol Psychother 2021; 29:164-177.

Abstract
The efficacy of individual cognitive-behavioural therapy (CBT) for eating disorders can be assessed by investigating the potential predictors, mediators and moderators of treatment. The present review focused on personality since its crucial role has been emphasized both by research and practice. Sixteen studies were collected, and data were extracted through a highly operationalized coding system. Overall, personality disorders were the most investigated construct; however, their influence was somewhat contradictory. A more cogent result occurred for borderline personality disorder (BPD) when considered as a moderator (not a predictor nor a mediator). Patients with a more disturbed borderline personality benefited to a greater extent from treatments including booster modules on affects, interpersonal relationships and mood intolerance, rather than symptoms exclusively. Nine additional personality dimensions, beyond BPD, were investigated sparsely, and results regarding them were barely indicative in this review. However, some of these dimensions (e.g., affective lability and stimulus-seeking behaviours) could be traced back to BPD, thereby strengthening evidence of the role of borderline disorder as a moderator. Although research on the relationship between personality and eating disorders needs to be increased and methodologically improved, personality, taken as a whole, emerged as a promising variable for enhancing the efficacy of CBT.

Abstract
Many treatments for eating disorders (ED) have demonstrated success. However, not all patients respond the same to interventions nor achieve full recovery, and obvious candidates like ED diagnosis and symptoms have generally failed to explain this variability. The current study investigated the predictive utility of personality for outcome in ED treatment. One hundred and thirty adult patients with bulimia nervosa or eating disorder not otherwise specified enrolled in an intensive multimodal treatment for 16 weeks. Personality was assessed with the NEO Personality Inventory Revised (NEO PI-R). Outcome was defined as recovered versus still ill and also as symptom score at termination with the Eating Disorder Inventory-2 (EDI-2). Personality significantly predicted both recovery (70% of patients) and symptom improvement. Patients who recovered reported significantly higher levels of Extraversion at baseline than the still ill, and Assertiveness emerged as the personality trait best predicting variance in outcome. This study indicates that personality might hold promise as predictor of recovery after treatment for ED. Future research might investigate if adding interventions to address personality features improves outcome for ED patients.

Abstract
There is growing evidence supporting a multifactorial etiology that includes genetic, neurochemical, and physiological components for eating disorders above and beyond the more conventional theories based on psychological and sociocultural factors. Ghrelin is one of the key gut signals associated with appetite, and the only known circulating hormone that triggers a positive energy balance by stimulating food intake. This review summarizes recent findings and several conflicting reports on ghrelin in eating disorders. Understanding these findings and inconsistencies may help in developing new methods to prevent and treat patients with these disorders.

Abstract
AIMS The aim of this study was to investigate the effects of temperament on quality of life and social adaptation in depressive patients with mood disorder. METHODS Forty-six consecutive depressive outpatients were investigated by using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version, the Munich Personality Test, the World Health Organization Quality of Life 26 (WHO QOL 26), and the Social Adaptation Self-evaluation Scale (SASS). The unpaired t-test, Pearson's r and multiple regression analysis were used to assess three variables (age, the number of temperaments and/or personality types, and Hamilton Depression Rating Scale scores) as independent variables with the scores of WHO QOL 26 and SASS as the dependent variables. RESULTS The number of temperaments and/or personalities and Hamilton Depression Rating Scale scores were significantly and negatively associated with WHO QOL 26 scores while only the number of temperaments and/or personalities was significantly and negatively associated with SASS scores. CONCLUSIONS The findings suggest that the combination of temperaments and/or personality types assessed with the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version and the Munich Personality Test may worsen both quality of life and social adaptation and that some temperaments and/or personality types in combination may be subclinical manifestations of mood disorders.
