- Abstract
Objective: Despite the multitude of research surrounding anorexia nervosa (AN) and perfectionism, there is yet to be a thorough investigation comparing perfectionism in those diagnosed with AN and other eating disorders, and other psychiatric diagnoses. The current meta‐analysis aimed to explore these comparisons. Method: Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) guidelines, we identified empirical studies that compared maladaptive and/or adaptive perfectionism scores in those diagnosed with AN and either a non‐clinical comparison group, people diagnosed with a non‐AN ED, or people diagnosed with another psychological disorder (i.e., other DSM diagnoses). In total, we identified 23 studies, comprising 3,561 participants who were all female. Comparison groups extracted from the studies were a non‐clinical group, bulimia nervosa (BN) diagnosis group, and another psychological diagnostic group. Results: When AN maladaptive perfectionism levels were compared against the comparison groups, the results showed that those diagnosed with AN were more perfectionistic compared to the non‐clinical group (g = 1.00), and the other psychiatric diagnosis group (g = 0.41). People diagnosed with AN also had higher levels of adaptive perfectionism levels compared to the non‐clinical group (g = 1.24). Comparisons between those diagnosed with AN and BN were statistically non‐significant for maladaptive perfectionism. Discussion: Although publication bias potentially affected the psychological diagnosis group comparisons, findings suggest that maladaptive perfectionism is a factor associated with both AN and BN.
