Abstract
The "pressure of the trainer" subscale of Multidimensional Inventory or Perfectionism in Sport, measures the tendency of athletes to perceive their coaches as sources of pressure to obtain a certain level of performance. The purpose of this study was to translate into Spanish spoken in Mexico eight items, and examine its psychometric properties (factorial validity, reliability, criterion validity). Participated 106 athletes of both sexes with a mean age of 12.5 years (SD=1.72). The results confirmed the unifactorial structure, where six of the eight items were valid for measuring the latent factor. The reliability of the subscale was adequate, and evidence was found from its relationship with other variables, since the coach's pressure was positively related to the fear of failure. In conclusion, this adaptation is valid and reliable after the elimination of two items, and can be used in research within the Mexican sports context.
