Response tendencies, ethnicity, and depression scores

Area of Science:

• Epidemiology
• Psychiatry
• Sociology

Background:

• The Center for Epidemiologic Studies Depression (CES-D) scale is a widely used measure for assessing depressive symptoms.
• Previous research has not fully explored the impact of response tendencies on depression prevalence estimates across diverse ethnic groups.

Purpose of the Study:

• To investigate whether response tendencies introduce bias in depression prevalence estimates.
• To examine the influence of response tendencies on the association between CES-D symptom scores and demographic variables in different ethnic groups.

Main Methods:

• A sample of white, black, and Mexican-American individuals in Alameda County, California, were administered the CES-D scale in 1978.
• Statistical analyses were conducted to assess the correlation between response tendencies, CES-D scores, and demographic factors, stratified by ethnicity.

Main Results:

• Response tendencies showed differential correlations with CES-D symptom scores across ethnic groups.
• Despite these differences, the magnitude of bias introduced by response tendencies was insufficient to alter most observed associations between symptom scores and demographic variables.

Conclusions:

• Response tendencies appear to have a limited impact on the validity of depression prevalence estimates and demographic associations in this sample.
• Further methodological research is recommended to refine the conceptualization and measurement of depression and related constructs.
