    Introducci贸n: La creaci贸n de instrumentos de medici贸n son aportes significativos para la medici贸n y el avance de la investigaci贸n cient铆fica. Objetivo: Dise帽ar y validar una Escala de Maltrato al Asesorado de Tesis (EMAT) en una muestra de tesistas peruanos. M茅todos: Estudio de dise帽o instrumental donde se dise帽贸 y se valid贸 una escala de 20 铆tems distribuidos en 3 factores (asesor, jurado y administrativos). Tuvo la participaci贸n de 274 tesistas(61,7% mujeres). Para analizar la evidencia de validez basada en el contenido se utiliz贸 el coeficiente V de Aiken, para la validez de constructo se recurri贸 al an谩lisis factorial confirmatorio y la confiabilidad fue estudiada a trav茅s del coeficiente omega. Resultados: Se obtuvieron propiedades psicom茅tricas adecuadas. Los 20 铆tems de la EMAT recibieron una evaluaci贸n favorable a trav茅s del juicio de expertos, el an谩lisis factorial confirmatorio apoya la estructura interna de 3 factores, reportando 铆ndices de bondad de ajuste satisfactorios, adem谩s, la correlaci贸n entre los factores fue significativa (p < 0,05) y la confiabilidad aceptable. Conclusi贸n: La EMAT es v谩lida y confiable para medir el maltrato hacia el asesorado de tesis.Introduction: The creation of measurement instruments are significant contributions to themeasurement and advancement of scientific research.Objective: To design and validate a Thesis Advisor Abuse Scale (EMAT) in a sample of Peruvianthesis students.Methods: Instrumental design study where a scale of 20 items distributed in 3 factors (advisor,jury and administrative) was designed and validated.

Objective To design and validate a Thesis Advisor Abuse Scale (EMAT) in a sample of Peruvian thesis students. Methods Instrumental design study where a scale of 20 items distributed in 3 factors (advisor, jury and administrative) was designed and validated. It had the participation of 274 thesis students (61.7% women). The Aiken V coefficient was used to analyze the evidence of content-based validity, the confirmatory factor analysis was used for construct validity, and reliability was studied through the Omega coefficient. Results Adequate psychometric properties were obtained. The 20 items of the EMAT received a favorable evaluation through expert judgment, the confirmatory factor analysis supports the internal structure of 3 factors, reporting satisfactory goodness-of-fit 铆ndices, in addition, the correlation between factors was significant (P<.05) and the reliability acceptable. Conclusion The EMAT is valid and reliable for measuring mistreatment of the thesis advisor
