This study examined the clinical correlates of lack of insight in bipo
lar disorder. In 28 acutely manic patients interviewed upon hospitaliz
ation and/or discharge, mean scores on the Insight and Treatment Attit
udes Questionnaire (ITAQ) improved only slightly, from 12.0 on admissi
on to 15.5 on discharge (p = .08), despite marked improvement in other
psychiatric symptoms. A reciprocal relationship was found between hig
her ITAQ scores and involuntary hospitalization (r = -.38). Like schiz
ophrenia, bipolar disorder appears to be a condition in which poor ins
ight is a prominent characteristic.
