The Use of a Comprehensive Concept of Capability for Wellbeing Assessment: A Best-Fit Framework Synthesis.

Developing an instrument with the capability approach can be challenging, since the capability concept of Sen is ambiguous concerning the burdens that people experience whilst achieving their capabilities. A solution is to develop instruments with a comprehensive concept of capability, such as the concept of 'option-freedom'. This study aims to develop a theoretical framework for instrument development with the concept of option-freedom. A best-fit framework synthesis was conducted with seven qualitative papers by one researcher. Two researchers supported the synthesis by discussing interim results during the synthesis. A priori concepts of option-freedom were used to deductively code against. Themes and subthemes were developed inductively when data did not match a priori themes. Seven paper were identified that fulfilled the eligibility criteria. Four themes emerged from the synthesis. (1) Option Wellbeing represents a range of options that need to be satisfied for individuals to experience wellbeing. (2) Self-Realization represents that there are experiences in an individual's life that have value beyond realizing options. (3) Perceived Access to Options represents the perceived ability of individuals to realize freedoms. (4) Perceived Control represents the experience of having control. Developing an instrument with the proposed framework has two benefits. First, it acknowledges the importance of assessing impediments in realizing capabilities for wellbeing assessment. Secondly, the themes form a broad informational base by including themes related to subjective wellbeing. Future research should study the feasibility of implementing the framework for instrument development.
