Objective: Long-acting injectable (LAI) antipsychotics improve treatment outcomes in patients with schizophrenia but are often reserved for only the most severely affected or nonadherent. Studies show cultural/racial differences in prescribing. This pilot study examined prescriber-patient interactions and cultural/racial differences in perceptions of LAIs among patients. Methods: A linguist analyzed 120 prescriber-patient conversations representing selected patient cultural/racial subgroups (European American, African American, Latino American; n=40 each) to identify similarities and differences in conceptualization and attitudes toward LAIs. Results: Of 35 LAI-naive patients offered LAIs, 9% (3/35) responded favorably, 46% (16/35) were neutral/passive, and 46% (16/35) had concerns or viewed LAIs as unfavorable. Among LAI-naive patients, favorable or neutral/passive responses were reported for 50% (7/14) of European Americans, 63% (10/16) of African Americans, and 40% (2/5) of Latino Americans. The majority of LAI-naive patients (57% [20/35]) accepted LAI prescriptions, including 53% (17/32) of those who initially were neutral/passive or refused treatment (European American, 42% [5/12]; African American, 53% [8/15]; Latino American, 80% [4/5]). Fifty-seven percent (68/120) of patients expressed treatment goals. Goals of positive/negative symptom control were associated with positive attitudes toward LAIs while patients with goals focused on control of anxiety and insomnia tended to have negative attitudes toward LAIs. Latino-American patients who expressed treatment goals seemed more focused on discomfort control (67% [12/18]); goals of European Americans and African Americans were more equally distributed. Conclusions: Equal numbers of LAI-naive patients had unfavorable/concerned or neutral/passive attitudes toward treatment; relatively few patients responded favorably. The limited sample size precludes cultural/racialspecific conclusions.
