Objectives: Cognitive flexibility and psychological distress, such as depression and anxiety, have been implicated in the aetiology of Anorexia Nervosa (AN). Despite the known associations between eating disorder (ED) symptoms, depression, anxiety, and cognitive flexibility, the specific pathways that connect these constructs are unclear. We therefore used network analysis to examine the relationship between these symptoms in an AN sample. Methods: One hundred and ninety‐three treatment‐seeking individuals diagnosed with AN (95.6% female, M = 26.89 [SD = 9.45] years old) completed self‐report measures assessing depression, anxiety, cognitive flexibility, and ED symptoms. To determine each symptom's influence in the network, we calculated the expected influence. Results: The two relationships with the greatest edges were those between (1) weight/shape concerns and eating/dietary restraint and (2) weight/shape concerns and psychological distress (a measure that combined depression and anxiety). Cognitive flexibility was not connected to weight/shape concerns but had negative partial associations with eating concerns/dietary restraint and psychological distress. There was also a slight, non‐zero connection between eating concerns/dietary restraint and psychological distress. Conclusions: The findings underscore the importance of weight/shape, eating/dietary concerns, and psychological distress in the AN network and suggest that addressing cognitive flexibility may be a useful target for eating concerns/dietary restraint and psychological distress. Future studies assessing the longitudinal course of psychopathology within the AN network structure may help in identifying whether specific symptoms function as risk factors or maintaining factors for this co‐occurrence.

Disturbances in eating behaviours and differences in personality characteristics, such as perfectionism, cognitive flexibility, and obsessive-compulsive behaviours, are commonly reported in individuals with eating disorders (ED) and can influence the development and maintenance of EDs. The presence of these characteristics in ED professionals may also have an influence on their patients. The aim of this study was to gain a better understanding of the presence of these behaviours and characteristics in ED clinicians/researchers (EDCR). This study examined whether these constructs differed amongst 83 EDCR and 47 general mental health clinicians/researchers (MHCR), who completed an online survey, measuring eating disorder symptomology, orthorexia nervosa, perfectionism, cognitive flexibility, and obsessive-compulsive traits. Significantly less dietary restraint, eating concerns and orthorexia nervosa behaviours, but significantly poorer ability to seek out alternative solutions (i.e. a component of cognitive flexibility) were found in the EDCR group compared with the MHCR group. Moderation analysis found no effect of ED history on the relationship between eating behaviours and group. These results suggest that working in the ED field may be a protective factor against developing certain disordered eating behaviours. However, poorer cognitive flexibility may adversely impact EDCRs, and should be considered when carrying out their clinical and/or research duties. [ABSTRACT FROM AUTHOR]

Introduction: Cognitive inflexibility, clinical perfectionism, and eating disorder (ED)-specific rumination are common characteristics reported in anorexia nervosa (AN) and may contribute to the maintenance of the illness. It is suggested that clinical perfectionism and rumination may mediate the relationship between cognitive flexibility and AN pathology; however, research to date has not investigated all these factors together. The aim of the current study was to explore the relationships between these factors and how they may relate to ED symptoms in AN. Methods: Participants included 15 women with a current diagnosis of AN, 12 women who had a past diagnosis of AN and were currently weight-restored, and 15 healthy controls (HCs). Results: The results revealed that participants with both acute and weight-restored AN self-reported poorer cognitive flexibility than HCs, but the groups did not differ in performance on objective assessments of cognitive flexibility. Participants with AN also reported significantly greater clinical perfectionism and ED-specific rumination than HC. A parallel mediation analysis found that ED-specific rumination mediated the relationship between subjective cognitive flexibility and ED symptoms. Further, subjective cognitive flexibility directly influenced ED symptoms. However, the mediation model was not significant for objective cognitive flexibility. Conclusion: The findings of this study have implications for potential treatment barriers and factors which might contribute to the risk of relapse. [ABSTRACT FROM AUTHOR]

Objective: Anorexia nervosa (AN) is a serious eating disorder associated with several cognitive difficulties including poor cognitive flexibility (i.e. difficulties in effectively adapting to changes in the environment and/or changing task demands). AN research has primarily assessed cognitive flexibility using neurocognitive tests, and little is known about the differences or similarities between self-report and neurocognitive assessments of cognitive flexibility. This study investigated the relationship between self-report and neurocognitive assessments of cognitive flexibility in people with no history of an eating disorder (n = 207) and people with a self-reported lifetime diagnosis of AN (n = 19). Methods: Participants completed self-report and neurocognitive assessments of cognitive flexibility through an online study. Results: No significant correlations were found between self-report and neurocognitive assessments of cognitive flexibility for either group of the sample, suggesting that these assessments may evaluate different aspects of cognitive flexibility. Further, negative mood and self-reported eating disorder symptoms were found to significantly relate to self-reported cognitive flexibility, but were not associated with performance on neurocognitive tests of cognitive flexibility. Conclusions: To provide a comprehensive understanding of perceived and objective cognitive flexibility in AN, future research and clinical assessments should include both self-report and neurocognitive assessments.

Objective: Anorexia nervosa (AN) is associated with clinical characteristics including eating disorder symptomatology, negative mood states, perfectionism and cognitive inflexibility. Whether these characteristics differ across illness stages, and are also present in first-degree relatives, demonstrating heritability, is unclear. The aim of this research was to compare current AN (c-AN), weight-restored AN (wr-AN), sisters of individuals with AN (AN-sis) and healthy controls (HC) on these measures. Method: Eighty participants (n = 20/group) completed the study. Results: Eating disorder symptomatology was similar among c-AN and wr-AN groups, whereas the AN-sis did not differ from either wr-AN or HC. Anxiety was significantly higher in c-AN, wr-AN and AN-sis groups, relative to HC. Increased perfectionism was identified in the c-AN and wr-AN groups compared to AN-sis and HC on the 'concern over mistakes', 'personal standards' and 'doubt and actions' subscales of the Multidimensional Perfectionism Scale. Group differences were not apparent on cognitive flexibility. Conclusions: These findings suggest that anxiety may be a risk factor or linked to genetic susceptibility for AN, as well as specific aspects of perfectionism that relate to self-imposed standards.

Impaired cognitive flexibility has been suggested as a risk factor for the development of anorexia nervosa (AN). The current study aimed to 1) investigate cognitive flexibility in people at various levels of risk of AN; and 2) compare people with a history of AN to people at different levels of risk of AN in cognitive flexibility. The sample comprised of 262 community participants (79% female) and 36 participants with a lifetime diagnosis of AN (97.2% female) aged between 18 and 64 years old. Participants completed self-report (the Depression Anxiety Stress Scale short-form version, the Eating Disorders Examination-Questionnaire, the Neuroticism Scale, and the Cognitive Flexibility Inventory) and neurocognitive (the Trail Making Test and the Wisconsin Card Sorting Test) assessments online to evaluate eating disorder symptoms, depression, neuroticism, and cognitive flexibility. Using a cluster analysis, participants were allocated into low-, medium-, and high-risk of AN groups (n = 88, 128, 46, and 36 respectively). Although high-risk participants self-reported significantly poorer cognitive flexibility than the other risk groups, performance on the neurocognitive tasks was similar across groups. Further, participants with lifetime AN reported significantly poorer cognitive flexibility than the low-risk group. People at high-risk of AN may perceive themselves to have poorer cognitive flexibility compared to those at a lower risk of AN. These results have implications for early identification of people at high-risk of AN. • High-risk participants self-report poorer cognitive flexibility than low-risk participants. • Participants with lifetime AN self-report poor cognitive flexibility. • No significant group differences in neurocognitive tests of cognitive flexibility.

Poor cognitive flexibility and perfectionism are common features in anorexia nervosa (AN). The current study aimed to investigate cognitive flexibility and clinical perfectionism as potential predictors of AN. Twenty women with a current diagnosis of AN (M age = 28.25, SD = 7.62) and 170 community participants with no lifetime history of an eating disorder (M age = 29.23, SD = 9.88) took part in an online cross-sectional study that included self-report questionnaires of cognitive flexibility and clinical perfectionism. It was found that compared to the community sample, women with AN self-reported significantly poorer cognitive flexibility and significantly greater clinical perfectionism. In a regression model, clinical perfectionism (but not self-reported cognitive flexibility) significantly predicted group membership. The specificity and sensitivity of the model were high. These preliminary findings indicate that clinical perfectionism may represent a key feature of AN and may accurately discriminate between participants with and without AN, though more research is required.

Difficulties in cognitive flexibility–the ability to adapt effectively to changes in the environment and/or changing task demands–have been reported in anorexia nervosa (AN). However, findings are inconsistent across studies and it remains unclear which specific aspects of cognitive flexibility patients with AN may struggle with. This systematic review aimed to synthesise existing research on cognitive flexibility in AN and clarify differences between patients with acute AN, patients who are weight-restored and patients who are fully recovered from AN. Electronic databases were searched through to January 2020. 3,310 papers were screened and 70 papers were included in the final review. Although adults with acute AN performed worse in perceptual flexibility tasks and self-report measures compared to HCs, they did not exhibit deficits across all domains of cognitive flexibility. Adolescents with acute AN did not differ to HCs in performance on neurocognitive tasks despite self-reporting poorer cognitive flexibility. Overall, significant differences in cognitive flexibility between acute and recovered participants was not evident, though, the findings are limited by a modest number of studies. Recovered participants performed poorer than HCs in some neurocognitive measures, however, results were inconsistent across studies. These results have implications for the assessment of cognitive flexibility in AN and targeted treatment approaches. • Adults with acute anorexia nervosa perform worse than HCs in perceptual cognitive flexibility. • Adults and adolescents with acute anorexia nervosa perform differently in cognitive flexibility. • Specific cognitive flexibility deficits in AN, not global impairments. • Recovered anorexia nervosa participants perform similarly to acute participants.

The Wisconsin Card Sorting Test (WCST) is a popular neurocognitive task used to assess cognitive flexibility, and aspects of executive functioning more broadly, in research and clinical practice. Despite its widespread use and the development of an updated WCST manual in 1993, confusion remains in the literature about how to score the WCST, and importantly, how to interpret the outcome variables as indicators of cognitive flexibility. This critical review provides an overview of the changes in the WCST, how existing scoring methods of the task differ, the key terminology and how these relate to the assessment of cognitive flexibility, and issues with the use of the WCST across the literature. In particular, this review focuses on the confusion between the terms ‘perseverative responses’ and ‘perseverative errors’ and the inconsistent scoring of these variables. To our knowledge, this critical review is the first of its kind to focus on the inherent issues surrounding the WCST when used as an assessment of cognitive flexibility. We provide recommendations to overcome these and other issues when using the WCST in future research and clinical practice. Refereed/Peer-reviewed
