The Big Five and subjective wellbeing: The mediating role of optimism

Cristina Serrano, Yolanda Andreu, and Sergio Murgui

Universidad de Valencia

Background: Previous literature has shown that personality is one of the most important predictors of Subjective Wellbeing. However, the mechanisms through which basic personality dispositions contribute to wellbeing have scarcely been explored. Therefore, in this study we examined the mediating role of Optimism in the relationship between the Big Five personality model (both factors and facets) and Subjective Wellbeing. Additionally, we assessed whether the results varied by sex. Method: A sample of 611 Spanish adolescents completed self-report measures of BFQ, LOT-R, and SHS. We conducted structural equation modeling to test the proposed mediating models. Results: Optimism completely mediated the relationship between Extraversion and Emotional Stability factors and Subjective Wellbeing. Likewise, Optimism mediated the relationship between the personality facets Politeness, Perseverance, Emotion control, Impulse control, and Dynamism and Subjective Wellbeing. The findings were invariant by sex. Conclusions: These results provide help in identifying the possible mechanisms through which basic dispositions of personality contribute to wellbeing. These findings can be used to develop interventions that target the promotion of greater Subjective Wellbeing through Optimism, and thereby improve adolescents’ adjustment.

Los Cinco Grandes factores de personalidad y el bienestar subjetivo: el papel mediador del optimismo. Antecedentes: los resultados de la investigación previa han mostrado que uno de los principales predictores del bienestar subjetivo es la personalidad. Sin embargo, los mecanismos a través de los cuales ésta contribuye al bienestar subjetivo permanecen prácticamente inexplorados. Por ello, el presente estudio examinó el papel mediador de optimismo en la relación entre el modelo de los Cinco Grandes (factores y facetas) y el bienestar subjetivo. Además, exploró la invarianza por sexo de los resultados. Método: seiscientos once adolescentes españoles completaron los auto-informes BFQ, LOT-R y SHS. Se realizaron modelos de ecuaciones estructurales para explorar los modelos de mediación propuestos. Resultados: optimismo medió totalmente la relación entre estabilidad emocional y extraversión y bienestar subjetivo. Además, también medió la relación entre las facetas de cordialidad, perseverancia, control de emociones, control de impulsos y dinamismo y bienestar subjetivo. Estos resultados fueron invariantes a través del sexo. Conclusiones: estos resultados permiten identificar mecanismos a través de los cuales la personalidad contribuye al bienestar y pueden ser utilizados para el diseño y desarrollo de intervenciones dirigidas a promover un mayor bienestar a través del optimismo, mejorando así el ajuste del adolescente.
