The maladaptive nature of Perfectionistic Automatic Thoughts (PAT) increases the importance of evaluating the construct. This study aims to identify different clusters of PAT in undergraduates, and to check possible inter-cluster differences in the dimensions of dispositional empathy and emotional intelligence in a sample of 691 Spanish undergraduates (Mage = 23.1; SD = 5.26). The Perfectionism Cognitions Inventory, the Interpersonal Reactivity Index and the Trait Meta-Mood Scale were used. Three clusters with low (LPAT), moderate (MPAT) and high (HPAT) levels of PAT were identified. Statistically significant differences were observed between these clusters in terms of dispositional empathy and emotional intelligence dimensions. HPAT significantly scored higher than LPAT on Fantasy, Empathic Concern, Personal Discomfort and Perception, as well as in comparison with MPAT on Fantasy, Empathic Concern, Personal Discomfort and Perception. Moreover, MPAT obtained significantly higher scores on Comprehension and Repair than LPAT. Effect sizes for these differences were of a small magnitude, except for the HPAT and LPAT contrasts, whose differences were of a moderate magnitude.
