Se construyó una Escala tipo Likert para medir actitudes hacia las palomas domésticas y se recopilaron evidencias de confiabilidad y validez para respaldar su uso en investigaciones psi-cológicas y educacionales. La validez de la Escala se evaluó mediante Juicio de Expertos y se obtuvieron valores de Coeficiente V de Aiken superiores a 0.8 para todos los ítems. La confiabi-lidad se evaluó mediante el método de consistencia interna, aplicando la Escala a una muestra de estudiantes de Estudios Generales de la Universidad Nacional Mayor de San Marcos, y se obtuvieron valores de Coeficiente Alfa de Cronbach superiores a 0.8 para la Escala total y para las sub escalas cognitiva, afectiva y conativa. Se concluyó que la Escala de 44 ítems es un in-strumento válido y confiable para evaluar actitudes de estudiantes universitarios.
A Likert Scale to measure attitudes towards feral pigeons was developed and evidence regar-ding reliability and validity was gathered to support its use in psychological and educational research. The validity of the Scale was evaluated by means of expert judges, and Aiken’s V Coefficient values higher than 0.8 were obtained. The reliability was evaluated by means of internal consistency method, applying the Scale to a sample of students from “Universidad Nacional Mayor de San Marcos”, and Cronbach’s Alpha Coefficient values higher than 0.8 were obtained for the total scale and the cognitive, affective, and conative sub scales. In conclusion, the 44 item Scale is a valid an reliable instrument to evaluate university student’s attitudes.
