Abstract: Abstract Research on Quality of Life (QOL) encompasses a variety of dimensions, with some studies examining the factors that influence QOL and others focusing on methods to enhance it. One of the challenges in this field is understanding how to improve QOL across different economic contexts. Within this spectrum, capability stands out as a key determinant of QOL. The substantial correlation between capability and QOL has been established by numerous previous studies. This research primarily explores aspects related to capability. The goals of this study were manifold. First, we aimed to investigate the link between poverty and various capability variables. Second, we intended to assess the relationship between capability and QOL. The third objective was to introduce grit as a mediator in the capability-QOL relationship. Lastly, we explored the comparison between two classes within the overall model. The Structural Equation Modeling (SEM) analysis indicated that capability variables do have an impact on QOL in the baseline model. However, when comparing models, the one representing individuals under the poverty line showed no significant relationship between capability and QOL. The introduction of a mediation variable led to the identification of a fully mediated model in the context of poverty within this study. The distinctive contribution of this research is highlighted by the mediation findings between the two models, underscoring the nuanced interplay between capability, grit, and QOL in the backdrop of economic challenges.
