Reliability of the CES-D Scale in different ethnic contexts

Area of Science:

• Psychometrics
• Mental Health Assessment
• Cross-cultural Psychology

Background:

• The Center for Epidemiologic Studies Depression Scale (CES-D) is a widely used 20-item symptom checklist for measuring depressive symptoms.
• Assessing the reliability and validity of psychological instruments across different demographic groups is crucial for equitable mental health research.
• Previous studies have sometimes shown variations in scale performance across ethnic groups, necessitating further investigation.

Purpose of the Study:

• To evaluate the reliability and data quality of the CES-D in a multi-ethnic community sample.
• To compare the performance of the CES-D among Anglos, Blacks, and Mexican Americans.
• To determine if the underlying factor structure of the CES-D is consistent across these ethnic groups.

Main Methods:

• Data were collected from community respondents comprising Anglos (n=254), Blacks (n=270), and Mexican Americans (n=181).
• Reliability was assessed using Cronbach's alpha and Spearman-Brown split-half coefficients.
• Factor analysis was employed to examine the response structure across groups.
• Missing data rates were compared among the ethnic groups.

Main Results:

• Despite a lower survey response rate for Mexican Americans, the quality of data provided was comparable to Anglos and Blacks.
• No significant differences were found among the groups regarding missing data.
• Internal consistency reliability (Cronbach's alpha, split-half) and factor-analytic results demonstrated consistent performance of the CES-D across all three ethnic groups.

Conclusions:

• The Center for Epidemiologic Studies Depression Scale demonstrates reliable and consistent psychometric properties across Anglo, Black, and Mexican American community samples.
• The findings support the use of the CES-D as a valid measure of depressive symptoms in these diverse populations.
• The consistent factor structure suggests cultural equivalence in the interpretation of the scale items.
