Ma. Burke et al., A PILOT-STUDY OF A STRUCTURED INTERVIEW ADDRESSING SEXUAL FUNCTION INMEN WITH SCHIZOPHRENIA, Biological psychiatry, 35(1), 1994, pp. 32-35
Twenty physically healthy men with schizophrenia responded to a 15-ite
m questionnaire inquiring about their usual and their present (on medi
cations) sexual functioning. Two summary measures of present impairmen
t (the average of items 7-13 that detail the patients' specific compla
ints of impairment, and item 15, the interviewer's global judgment of
impairment) were significantly correlated with each other and with the
differences between usual and present reported frequencies of erectio
n and masturbation. More severe impairment on these summary measures w
as significantly associated with greater biological evidence of dopami
ne blockade (more severe extrapyramidal side effects and higher serum
prolactin levels).
