Assessing coping has been a controversial subject and to this day, there is no consensus about its dimensionality. A short version for adolescents and college students of Moos' Coping Responses Inventory-Youth Form is presented. Psychometric analyses performed with 1,160 Argentinean students included: a) descriptive statistics, b) confirmatory factor analysis, and c) internal consistency. Three models (1-factor, 2-factor and 4-factor) were compared in two randomized samples, and by a bootstrap procedure carried out in 500 different samples. Nested models with progressive restrictions were also established successively in samples split by sex and age. Results indicated a better fit of the 4-factor model as well as its stability across different groups.
