This paper indicates the necessity for clinicians, especially Anglo-American clinicians, who provide services to individuals from the Puerto Rican population, to be conscious of their possible prejudice toward them; they should also be aware of the negative attitude which frequently occurs on the part of the patient. It is crucial that clinicians be sensitized to the culturally-based attitudes and beliefs prevalent among Puerto Ricans and to their healthy, as well as pathological, dispositions. Finally, when it is necessary to interview the patient in English, the clinician must be aware of the effects of the language on the content of the verbal productions of the patient and should evaluate any cues carefully before deeming them indicators of psychopathology.
