Tanto en la investigación como en la práctica profesional, la medición precisa de las variables es esencial
para garantizar la exactitud de las conclusiones y la eficacia de las intervenciones. Obtener instrumentos
de medición válidos y confiables es una tarea compleja. La presente GuÃa describe de manera detallada
los procedimientos de construcción y validación de escalas tipo Likert para evaluar variables
psicosociales y de la salud, con las mejores prácticas psicométricas. Está dividida en dos etapas. La
Etapa I inicia con el encuadre del constructo a medir, continúa con la elaboración de los reactivos y su
validación por expertos, y concluye con los pasos para la integración de la escala, su piloteo y su
aplicación. En la Etapa II se presentan las operaciones necesarias para preparar la base de datos y para
efectuar los análisis estadÃsticos requeridos para el cálculo de los Ãndices de confiabilidad y para obtener
las distintas evidencias de validez para la escala; finalmente, se indica cómo elaborar pautas de
interpretación de los puntajes. También se incluyen procedimientos para la valoración, traducción y
adaptación de escalas existentes.
Todos los pasos de la GuÃa son ejemplificados con casos prácticos. Se ofrecen recomendaciones y
recursos útiles y se proporcionan formatos para concentrar los resultados. Además, se detalla el uso de
programas estadÃsticos para la validación de los instrumentos (SPSS, FACTOR y AMOS), en particular,
para realizar análisis factoriales exploratorios y confirmatorios. Aunque el enfoque de la obra es
eminentemente práctico, la GuÃa muestra los fundamentos teóricos contemporáneos que apoyan cada
procedimiento.
Para los investigadores, profesionales y estudiantes que se proponen desarrollar y validar escalas de
manera rigurosa y con alta calidad psicométrica, la GuÃa constituye una herramienta imprescindible, tanto en PsicologÃa, Biomedicina y Neurociencias como en Educación, Mercadotecnia, SociologÃa y Ciencia PolÃtica.
