Do they see dead people? Cultural factors and sensitivity in screening for schizophrenia spectrum disorders

ABSTRACT

Objective. Schizophrenia spectrum disorders (SSDs), are diagnosed more frequently among African-Americans (AAs) than Caucasians. It has been suggested that cultural differences in symptom presentation and endorsement (including reporting spiritual/religious experiences) may influence this disparity. The current study investigated the relationship between endorsement of spiritual auditory and visual hallucinations and subsequent diagnosis of SSD among AA patients.

Design. Participants (N = 471 AAs) completed the Mini International Neuropsychiatric Interview-Plus (MINI-Plus) Screening Interview as part of their intake to a HIV outpatient clinic. Endorsement of auditory or visual (A/V) hallucinations was explored with the MINI-Plus Psychotic Disorder Module and questions regarding the content of the unusual experience.

Results. Logistic regression indicated that endorsement of A/V hallucinations significantly predicted a SSD (OR = 41.6, 95% CI 13.7-126.0, p < .001). However, when hallucinations were spiritual in nature, odds of an SSD fell dramatically (OR = 0.22, 95% CI 0.07-0.64, p < .001).

Conclusions. The current study indicates that not all visual and auditory hallucinations are symptomatic of a psychotic disorder in AA patients. Many of these experiences may be related to spirituality. Clinicians assessing AA patients need to query content of, meaning attributed to, and distress associated with A/V unusual experiences.
