El objetivo de este estudio es analizar las propiedades psicométricas de los cuestionarios Mental Toughness Index (MTI) y Sports Mental Toughness Questionnaire (SMTQ), para su adaptación y empleo en el ámbito del deporte mexicano. El MTI consta de ocho ítems y constituye una medida unidimensional de la fortaleza mental. El SMTQ está compuesto de 14 ítems, con tres factores (confianza, constancia y control). La muestra estuvo compuesta por 375 deportistas de diferentes disciplinas. Los resultados indican unas apropiadas características del MTI y su estructura unidimensional, con una fiabilidad de =.81, cargas factoriales adecuadas, índices de bondad y ajuste satisfactorios, y validez convergente. El SMTQ obtiene peores resultados, con =.69 para la escala total, y baja fiabilidad de constancia y control. Los índices de ajuste no son óptimos, y existen correlaciones bajas entre escalas y problemas de validez discriminante.
The objective of this study was to analyze the psychometric properties of the Mental Toughness Index (MTI) and Sports Mental Toughness Questionnaire (SMTQ), for their adaptation and use in the field of Mexican sport. The MTI consists of eight items and constitutes a one-dimensional measure of mental toughness. The SMTQ is composed of 14 items, with three factors (confidence, constancy, and control). The sample was composed of 375 athletes from different sports. The results indicated appropriate characteristics of MTI and its one-dimensional structure, with a reliability of =.81, adequate factor loads, satisfactory goodness and fit indices, and convergent validity. The SMTQ presented inferior results, with =.69 for total scale, and low reliability of constancy and control. Fit indices were not optimal, and there were low correlations between scales and discriminant validity problems.
