Resumen
- español
  El estudio analiza la intención de compra de alimentos modificados genéticamente en consumidores españoles mayores (Generación X y Baby Boomers) mediante el modelo TRA y una muestra de 248 personas. Con PLS-SEM (R²=0,71) se observa que las normas subjetivas influyen positivamente con mayor fuerza, la utilidad percibida también impacta positivamente y el riesgo percibido lo hace negativamente. El valor percibido actúa de forma indirecta a través de la utilidad. Las variables sociodemográficas no resultan significativas. El NCA identifica la utilidad y el valor percibidos como condiciones necesarias para una alta intención de compra.

  This study analyses purchase intention toward genetically modified foods among older Spanish consumers (Generation X and Baby Boomers) using the TRA framework and a sample of 248 respondents. PLS-SEM results (R² = 0.71) show that subjective norms have the strongest positive effect, perceived usefulness also has a positive impact, and perceived risk has a negative effect. Perceived value influences intention indirectly through usefulness, while sociodemographic variables are not significant. NCA findings identify perceived usefulness and perceived value as necessary conditions for achieving high purchase intention.
