The aim of the study was to understand the components associated with the types of perfectionism described as adaptive/healthy, maladaptive/unhealthy or non-perfectionism, which could offer positive or negative aspects to improve excellence and welfare, exploring the number and content of the latent perfectionism structure as a multidimensional construct in a sample of High Intellectual Abilities (HIA) students. Links with Positive and Negative perfectionism were also compared across perfectionism latent profiles. A total of n=137 HIA students, mean age 13.77 years (SD=1.99), participated in a survey. The Almost Perfect Scale Revised (APS-R) and Positive and Negative Perfectionism Scale-12 (PNPS-12) were used. Results obtained showed three latent classes (LC): 'Unhealthy' (LC1), 'Healthy' (LC2) and 'No perfectionism' (LC3). LC1 showed high scores on Discrepancy subscales but low in Order and High Standards. LC2 displayed higher scores on High Standards and Order. LC3 displayed lowest scores across all perfectionism facets. Statistically significant differences were found across latent profile in almost all perfectionism features. Different patterns of associations with Positive and Negative perfectionism were obtained across latent profiles. These findings address the latent structure of perfectionisms in HIA students and allow us to delimit, analyze, and understand the tentative latent profiles within the HIA arena.
