Summary
The EQ-Health and Well-being (EQ-HWB)-9 instrument effectively measured quality-of-life improvements in a Brazilian vulnerable population after a 6-month social intervention, demonstrating its responsiveness for health outcome monitoring.
Area of Science:
- Health Services Research
- Quality of Life Measurement
- Social Intervention Outcomes
Background:
- The EQ Health and Well-being (EQ-HWB) instrument assesses quality of life in health and social care.
- Evaluating the responsiveness of its short version, EQ-HWB-9, is crucial for vulnerable populations.
Purpose of the Study:
- To evaluate the responsiveness of the EQ-HWB-9 instrument.
- To assess its utility in a Brazilian vulnerable population undergoing a social intervention.
Main Methods:
- A pre- and postcohort design evaluated a 6-month multidimensional social intervention.
- Data from 98 participants were collected using electronic questionnaires (EQ-HWB-9, EQ-5D-5L, Perceived Change Scale).
- Responsiveness was analyzed using statistical tests and subgroup analyses.
Main Results:
- EQ-HWB-9 successfully differentiated between groups with varying health statuses and perceived changes.
- Significant improvements were noted from baseline to follow-up for EQ-HWB-9 and EQ-5D-5L (P < .001).
Conclusions:
- The EQ-HWB-9 demonstrated responsiveness to change over 6 months in a Brazilian vulnerable population.
- The findings suggest EQ-HWB-9 is useful for monitoring outcomes in multidimensional social programs.
