Inconsistencies in diagnosis and symptoms among bilingual and English-speaking Latinos and Euro-Americans.

Objective: Little information is available about accuracy of diagnoses in clinical care for affective and other major mental disorders experienced by Latino patients. This study addressed two central research questions: Do Latinos have disproportionate rates of clinical diagnoses of major depression based on structured diagnostic interviews? Are diagnostic patterns consistent with patient profiles and medical record information?

Methods: A total of 259 bilingual Latino, monolingual English-speaking Latino, and Euro-American patients aged 18 to 45 years with a history of severe depression or psychotic symptoms were compared across three clinical sites by using structured interviews.

Results: Compared with Euro-Americans, bilingual Latinos had significantly higher rates of major depression and significantly lower levels of mania. No significant differences were found between monolingual English-speaking Latinos and Euro-Americans.

Conclusions: Results suggest that the diagnostic process is affected by an apparent association with cultural-linguistic influences, notably speaking English as a second language.
