This study examined the relationships between adaptive and maladaptive perfectionism, anxious and avoidant adult attachment styles, depression, hopelessness, and life satisfaction among a sample of 180 undergraduate students. Maladaptive perfectionism mediated the relationship between both forms of adult attachment and depression, hopelessness, and life satisfaction. Adaptive perfectionism mediated the relationship between avoidant adult attachment and hopelessness and life satisfaction. Implications for counselors and future research directions are discussed.
