Maladaptive perfectionism is a common factor in many disorders and is correlated with some personality dysfunctions. Less clear is how dimensions, such as concern over mistakes, doubts about actions, and parental criticism, are linked to overall suffering. Additionally, correlations between perfectionism and personality disorders are poorly explored in clinical samples. In this study we compared a treatment seeking individuals (n=93) and a community sample (n=100) on dimensions of maladaptive perfectionism, personality disorders, symptoms, and interpersonal problems. Results in both samples revealed maladaptive perfectionism was strongly associated with general suffering, interpersonal problems, and a broad range of personality disordered traits. Excessive concern over one's errors, and to some extent doubts about actions, predicted unique additional variance beyond the presence of personality pathology in explaining symptoms and interpersonal problems.

Poor awareness of one's own emotions and theory of mind appears to be a feature of many adult psychiatric conditions. In this study, we explored whether alexithymia and poor understanding of irony, both elements of the metacognitive system, were impaired in a clinical sample (n = 20) when compared to a non-clinical group (n = 35). We expected that both elements were impaired in the clinical group and explored whether they were correlated with personality disorder traits, global symptomatology, depression and anxiety. Finally, we sought to investigate whether alexithymia and difficulties in irony comprehension were related to each other. Results partially supported our hypotheses. Both emotional awareness and irony comprehension were impaired in the clinical vs. non-clinical sample. Alexithymia was related to personality disorder
