The chapter "The Dimensions of Perfectionism" by Randy O. Frost, Patricia Marten, Cathleen Lahart, and Robin Rosenblate from Smith College explores the multifaceted nature of perfectionism. Perfectionism is a significant diagnostic criterion for various mental health disorders, yet it lacks a precise definition and has been understudied. The authors developed a multidimensional measure of perfectionism, which identified six major dimensions: excessive concern over making mistakes, high personal standards, perception of high parental expectations, perception of high parental criticism, doubting the quality of one’s actions, and a preference for order and organization. These dimensions were tested in four separate studies, revealing correlations with various psychopathological symptoms and procrastination. The Multidimensional Perfectionism Scale (MPS) showed high correlation with existing measures of perfectionism, while other measures were only moderately correlated. The study suggests that future research should consider the multidimensional nature of perfectionism. The chapter also highlights the distinction between normal and neurotic perfectionists, emphasizing that the critical evaluation tendencies associated with perfectionism, rather than the setting of high standards, are more closely linked to psychological problems.The chapter "The Dimensions of Perfectionism" by Randy O.
