Se indaga sobre la relación que existe entre el bienestar psicológico y la autoeficacia en una muestra de 153 universitarios migrantes de Lima Metropolitana, con una edad promedio de 21,43 años (D.E.= 2.12), de los cuales el 62% fueron mujeres y el 38% varones de universidades privadas de Lima. Se emplearon como instrumento de medida, la escala de bienestar psicológico, adaptada al contexto peruano por Domínguez (2014) y la escala de autoeficacia General empleada por Terry (2008). Los resultados muestran una correlación positiva entre la autoeficacia y las variables de aceptación y control (r = .295, p< .01) y autonomía (r = .411, p< .01). Además, se muestran diferencias estadísticamente significativas al comparar el bienestar psicológico entre quienes tienen y no pareja; mientras que se observan estadísticamente significativas al comparar la autoeficacia en función a tener o no pareja, género y edad. Se concluye que algunas dimensiones del bienestar psicológico se relacionan con la autoeficacia; además se observan diferencias significativas al comparar ambas variables entre otras de tipo sociodemográfico. / The relationship between psychological wellbeing and self-efficacy is investigated in a sample of 153 university migrants from the province to Metropolitan Lima, with an average age of 21.43 years (SD = 2.12), of which 62% were women and 38% men from private universities in Lima. The scale of psychological wellbeing, which is adapted to our environment by Domínguez (2014) and the scale of general self-efficiency used by Terry (2008), was used as a measuring instrument. The results show a positive correlation in relation to self-efficacy and acceptance and control variables (r = .295, p <.01) and autonomy (r = .411, p <.01). In addition, statistically significant differences are shown when comparing psychological well-being between those who have and not a partner; while it is observed statistically to compare when comparing self-efficacy according to having or not having a partner, gender and age. It is concluded that some dimensions of psychological well-being are related to self-efficacy; In addition, different differences are observed when comparing both variables among others of sociodemographic type. / Tesis
