Area of Science:

• Psychology
• Sociology

Background:

• Positive Health (PH) is crucial for measuring adaptation to challenges.
• Existing PH measures lack contextual factors.
• A Context-specific Positive Health (CPH) instrument aligned with the Capability Approach (CA) is needed.

Purpose of the Study:

• Develop and validate a Context-specific Positive Health (CPH) measurement instrument.
• Align the CPH instrument with the Capability Approach (CA).
• Incorporate contextual factors and resilience into PH measurement.

Main Methods:

• Developed and validated the CPH questionnaire (CPHQ) in two stages: preparation and validation.
• Used focus groups and expert consultations in the preparation phase.
• Tested factorial and concurrent validity in a representative sample (N=1002) using Factor Analysis and Multivariate Regression Analysis.

Main Results:

• The CPHQ demonstrated adequate factorial and concurrent validity.
• The questionnaire includes an assessment of resilience, a key component of PH.
• The final CPHQ comprises 11 dimensions, including relaxation, autonomy, social support, and health literacy.

Conclusions:

• The developed CPHQ is a theoretically embedded and validated measurement tool for Positive Health.
• The CPHQ addresses the ability to adapt, health inequality, and contextual factors.
• The instrument facilitates the development of understandable measurement items for PH.
