Valid and comparable measures are imperative to identify health disparities. This study compares the reliability and validity of self-report measures between English- and Spanish-speaking employees (n=408 for English, 62 for Spanish) in the job stress context. Measured variables included low back pain (LBP) symptoms as well as perceived characteristics of the job and workplace. Measures addressing the nature of social interactions at work (e.g., social support) and well-being (e.g., pain, perceived job stress) had high reliability for both languages. However, measures assessing characteristics of work (e.g., workload) had low reliability for Spanish-speaking employees. Among the measures with acceptable internal consistency (Cronbach alpha >.70), the self-reported LBP symptom score was highly correlated with an objective measure of back functioning obtained from lumber motion monitoring for English-speaking employees but not for Spanish-speakers. Self-report measures of social environment at work are highly correlated with a perceived job stress score for English-speaking employees but not for Spanish-speakers. Recommendations for future survey studies will be discussed.
