Assessing the Validity of Self-rated Health Across Ethnic Groups: Implications for Health Disparities Research.

OBJECTIVES

This study examines the association between morbidity (i.e., chronic health conditions) and self-rated health (SRH) with the aim of testing the within-group and across-group validity of SRH across nine ethnic groups: non-Latinx White, Mexican, Puerto Rican, Cuban, African American, Afro-Caribbean, Chinese, Filipino, and Vietnamese Americans. In addition, we assess whether acculturation (i.e., nativity, years of US residency, language of interview) and health-related factors (e.g., mental disorder) account for ethnic distinctions in SRH.

DESIGN

Data are from the National Survey of American Life (NSAL) and the National Latino and Asian American Study (NLAAS) (N = 8338). Weighted proportions and means for SRH and chronic conditions are reported. Ordered logistic regression analysis is used to determine ethnic group patterns in SRH.

RESULTS

Despite evidence of within-group validity of SRH for each ethnic group, our results seriously challenge the across-group validity of SRH. For example, Chinese and Vietnamese respondents report lower SRH despite having fewer chronic conditions relative to non-Latinx Whites. Moreover, Mexican Americans report fewer chronic health problems but lower SRH compared to non-Latinx Whites. Acculturation factors (e.g., language of interview) partially explain the Mexican-White difference in SRH. Among Chinese Americans, completing an interview in English is associated with higher SRH relative to those who completed an interview in Chinese.

CONCLUSION

These findings have implications for health disparities research that uses SRH as the dependent measure. Studies that compare the health profiles of diverse ethnic groups should use the SRH measure with caution, as SRH does not align with ethnic patterns of morbidity.
