espanolResumen La ausencia de instrumentos validos para medir variables relacionadas con las conductas saludables en Mexico, nos lleva al objetivo de adaptar y validar al idioma espanol hablado en Mexico la escala Grit y el cuestionario de autorregulacion del tratamiento (TSRQ) de la dieta, y explorar la relacion entre el Grit y la motivacion hacia la alimentacion saludable como evidencia de validez. 353 adultos del estado de Nuevo Leon respondieron a la escala Grit adaptada al espanol conformada por 12 items distribuidos en dos factores (consistencia del interes y perseverancia del esfuerzo) y al TSRQ adaptada al espanol compuesto por 15 items en tres factores (motivacion autonoma, motivacion controlada y no motivacion). Los resultados mostraron indices de ajuste aceptables para la version larga y corta de la escala Grit confirmando su estructura bifactorial. Ademas, se encontraron indices de ajuste aceptables para el TSRQ de la dieta indicando la presencia de tres factores latentes. Se observaron relaciones significativas y positivas entre el Grit y la motivacion autonoma, y de manera negativa con la motivacion controlada y no motivacion. Los analisis realizados indican que los instrumentos administrados son herramientas validas y confiables para ser utilizadas en Mexico. EnglishAbstract The lack of valid tools to measure variables related to healthy behaviors in Mexico has led the authors to adapt and validate the Grit Scale and the Treatment Self-Regulation Questionnaire (TSRQ) for diet into Mexican Spanish, and explore the relationship between grit and types of motivation towards healthy eating as evidence of validity. The Grit Scale and the TSRQ in Spanish were put to 353 adults from the state of Nuevo Leon, Mexico. The Grit Scale was composed of 12 items distributed into two factors (consistency of interest and perseverance of effort), and the TSRQ for diet was composed of 15 items distributed into three factors (autonomous motivation, controlled motivation, and amotivation). Results showed acceptable fit indices for the long and short versions of the Grit Scale, confirming its two-factor structure. In addition, acceptable fit indices were found for the TSRQ for diet, indicating the presence of three latent factors. Significant and positive relationships were found between grit and autonomous motivation, and negative relationships with controlled and amotivation. The analyses carried out indicated that the instruments administrated are valid and reliable tools for use in Mexico.
