La decisión de emigrar es compleja y tiene importantes consecuencias. Quienes emigran suelen ser los más educados y menos satisfechos con su situación en su país de origen, pero se desconocen sus estilos decisionales, si experimentan pesar al decidir y cómo eso se asocia con su bienestar y salud. Esto es analizado en 261 migrantes sudamericanos adultos, de ambos sexos, residentes en Talca (Chile), elegidos por disponibilidad, quienes respondieron instrumentos para medir estilos decisionales, pesar, bienestar y salud. Se observa una fuerte tendencia a la maximización, alto pesar, alto bienestar, y una autoevaluación de salud muy favorable. Se registran asociaciones positivas significativas de maximización con pesar (.374, p = .01), con bienestar (.161, p = .009) y con tres dominios de la calidad de vida relacionada con la salud (.174, p = .005; .169, p = .006; .212, p = .001). Se discuten los resultados y se sugieren nuevos estudios. [The decision to emigrate is complex and has important consequences. Those who emigrate are usually the most educated and least satisfied with their situation in their country of origin. However, their decision-making styles, whether they experience regret when deciding, and how is this associated with their well-being and health, are unknown. This is analyzed in 261 adult South American migrants, mostly Venezuelans, of both sexes, residing in Talca(Chile), chosen by availability, who answered instruments to measure decisional styles, regret, well-being, and health. A strong tendency to maximization, high regret, high well-being and a very favorable health self-evaluation are observed. There are also significant, positive associations of maximization with regret (.374, p = .01), with well-being (.161, p = .009)and with three domains of health-related quality of life(.174, p = .005; .169, p = .006; .212, p = .001). The results are discussed, and new studies are suggested].
