Hypothesis
The study aimed to test the validity and reliability of the SF-8 with a conflict-affected population in northern Uganda.
Conclusion
The study provides evidence on the reliability and validity of the SF-8 amongst internally displaced persons in northern Uganda.
Supporting Evidence
- The SF-8 showed excellent data quality with only 0.3% of respondents answering less than half of the items.
- Test-retest reliability results showed a good agreement with ICC of 0.61 for PCS and 0.68 for MCS.
- Principal component analysis indicated strong construct validity for the SF-8.
Takeaway
The SF-8 is a quick survey that helps understand how people feel about their health, especially in places affected by conflict.
Methodology
A cross-sectional multi-staged, random cluster survey was conducted with 1206 adults in camps for internally displaced persons.
Limitations
The HTQ and HSCL-25 used for validity tests have not been validated in northern Uganda, and the study did not assess the responsiveness of the instrument over time.
Participant Demographics
60% of respondents were women, mean age was 35 years, and 91% were from the Acholi tribe.
