“…However, these studies investigated multidimensional perfectionism that encapsulates broader perfectionism concepts, including adaptive and external motivations, rather than clinical perfectionism that focuses on the dysfunctional, intrinsically motivated concept of perfectionism. Consistent with current results, Yung and Tabri found clinical perfectionism was directly and indirectly associated with ON symptoms via defining oneself with an inflated focus on health [ 41 ]. Yung and Tabri’s results evaluating clinical perfectionism outside of the boundaries of eating, weight, and appearance suggest perfectionism may extend to multiple domains in an individual’s life, presenting as a vulnerability to becoming obsessed and fixated in various manifestations.…”

“…However, few studies have investigated the relationship between clinical perfectionism and ON. Yet, Yung and Tabri found a positive indirect relationship between clinical perfectionism and ON symptoms in participants demonstrating erroneous beliefs about eating safely and effectively [ 41 ]. Further, Pollack and Forbush found that perfectionism combined with neuroticism moderated the relationship between OC symptoms and body dissatisfaction [ 20 ].…”

Purpose Orthorexia nervosa (ON), a proposed disorder describing an obsessive focus on “healthy” eating, is characterised as having overlapping symptoms with obsessive–compulsive disorder. However, ON/obsessive–compulsive (OC) symptom relationships are inconsistently reported. The current study aimed to investigate if the contribution of OC symptoms and beliefs explain variability in ON symptoms and determine if perfectionism, a transdiagnostic factor, moderates the ON/OC symptom relationship. Methods The study comprised 190 participants (Mage = 28.63, SDage = 9.88; 80% female) recruited via an undergraduate research programme, social media, advocacy organisations, and a participant registry. Participants completed an online questionnaire assessing ON, OC, and perfectionism symptoms. Results A linear regression analysis found OC symptoms and beliefs explained 22.9% variability in ON symptoms (p < 0.001, f2 = 0.38) and perfectionism moderated the ON/OC symptom relationship, where higher levels of perfectionism with higher levels of OC symptoms was associated with higher levels of ON symptoms, explaining 2.2% variability (p = .01, f2 = 0.03). Conclusion OC symptoms appear more common in ON than previous studies indicate. However, the interaction between perfectionism and OC symptoms may drive obsessions in ON. Findings help refine our current understanding of ON phenomenology with implications for ON treatment development. Future research should further explore perfectionism in ON phenomenology. Level of evidence: Level V (Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees).

“…Participants were contacted via email every 2 hours between 9 am and 7 pm for 14 days to complete the 4‐item appearance focused self‐concept scale (Bossom & Tabri, 2022; Yung & Tabri, 2022), among other measures not examined herein (see OSF for these measures). The four appearance focused self‐concept items were drawn from the Beliefs About Appearance Scale (Spangler & Stice, 2001), which we adapted for use in experience sampling.…”

“…As well, areas of life that are perceived to be more important than others in the self‐concept have a significant influence on self‐definition and thus the evaluation of self‐worth. Critically, people may develop mental and physical health problems when they place overriding importance on a single area of life in their self‐concept (Tabri et al, 2017; Veale, 2002; Yung & Tabri, 2022). In the Transdiagnostic Cognitive‐Behavioral Theory of Eating Disorders (Fairburn, 2008; Fairburn, Cooper, et al, 2003), the extent to which people overvalue the importance of body shape/weight for self‐definition and self‐worth is considered the ‘core psychopathology’ that maintains disordered eating in anorexia nervosa and bulimia nervosa.…”

ObjectiveAppearance focused self‐concept (i.e., overvaluing the importance of appearance for self‐definition and self‐worth) is theorized to predict dietary restraint and binge eating in the short‐term (e.g., daily life). Yet, no research has examined whether appearance focused self‐concept increases within‐persons during a day and if such increases are linked to greater dietary restraint and binge eating for that day. We addressed this gap in knowledge.MethodSixty‐three female university students completed four items from the Beliefs About Appearance Scale as a measure of appearance focused self‐concept six times per day (9 am, 11 am, 1 pm, 3 pm, 5 pm, and 7 pm) for 14 days. Daily at 9 pm, they completed measures of dietary restraint and binge eating for that day.ResultsAnalyzing data from 555 days, latent growth curve analyses revealed a small‐to‐moderate linear increase in appearance focused self‐concept from 9 am to 3 pm that plateaued from 3 to 7 pm. A more rapid linear increase in appearance focused self‐concept from 9 am to 3 pm was associated with greater binge‐eating frequency during that day, but not with dietary restraint. The findings were observed when adjusting for between‐day appearance focused self‐concept at 9 am, which was positively associated with dietary restraint and binge‐eating frequency.DiscussionFindings are discussed in relation to research on appearance focused self‐concept as a risk factor for disordered eating. Findings are also discussed in relation to how sociocultural factors may increase appearance focused self‐concept over time. Future research should delve into the within‐day dynamic interplay between appearance focused self‐concept and disordered eating.Public significanceOur study revealed a noteworthy increase in the importance women attach to their appearance over the course of a day, correlating with increased binge eating during that day. Additionally, heightened appearance importance at the onset of a day was associated with more dietary restraint and binge eating during that day. These findings suggest a shorter timescale for the connection between appearance importance and disordered eating than previously understood.

“…For instance, in their study Yung and Tabri also found an indirect positive association between perfectionism and ON symptoms. Their study suggests that an explanation of this association might be linked to the fact that when an individual is aiming to eat in a healthy manner, perfectionism, in such cases, might emphasize ON symptoms indirectly by favoring a health-focused self-concept [61]. And hence "perfect healthy food" and perfectionist behaviors are rhyming ideations and the presence of one could increase the risk of the coexistence of the other.…”

The indirect role of orthorexia nervosa and eating attitudes in the association between perfectionism and muscle dysmorphic disorder in Lebanese male University students – results of a pilot study

Background The literature highly concentrates on disorders related to body image among women but only minimally when it comes to the male population; hence, in order to provide general practitioners, and primary care physicians in general, and psychiatrists in particular, with additional information concerning muscle dysmorphia among male university students in Lebanon, this study seemed essential, and was therefore conducted to (1) identify the prevalence of MDD, and (2) evaluate the indirect effect of eating attitudes in general and orthorexia nervosa in particular, in the association between perfectionism and muscle dysmorphic disorder (MDD) among a sample of male university students. Methods In this cross-sectional study conducted between September 2021 and May 2022, 396 male university students from multiple universities in Lebanon filled the online Arabic questionnaire. Results The results showed that 26 (6.6%) of the participants had MDD. Orthorexia nervosa and eating attitudes mediated the association between perfectionism and MDD; higher perfectionism was significantly associated with higher ON and more inappropriate eating; higher ON and more inappropriate eating were significantly associated with higher MDD, whereas perfectionism had a significant total direct effect on MDD. The high prevalence of MDD among male university students in Lebanon implies further investigation on the national level in the country. Conclusion Awareness campaigns among the university students could be adopted at the national level to increase the level of knowledge on the concepts of obsessive self-destructive perfectionism, orthorexia nervosa and muscle dysmorphia.
