Resumen
En una muestra de 227 adolescentes, esta investigación estudió, primero, la utilidad predictiva incremental de la similaridad al prototipo, una vez controladas las variables de la teoría de la conducta planificada (TCP) y, segundo, la contribución predictiva diferencial de los dos componentes del control conductual percibido: expectativa de autoeficacia y anticipación de dificultades. Los resultados evidenciaron que: 1) la intención y consumo de tabaco fueron predichos por las variables TCP (salvo norma subjetiva). 2) La similaridad al prototipo mejoró significativamente la predicción de intención y conducta. 3) Ambos componentes del control percibido predijeron la intención, pero sólo autoeficacia predijo la conducta. Globalmente considerados, estos resultados: son consistentes con la investigación realizada desde la TCP; muestran el incremento en capacidad predictiva aportado por la percepción de similaridad al prototipo; evidencian la contribución diferencial de autoeficacia y anticipación de dificultades a la predicción de la intención y conducta.
