This study extends research into insight by examining its relationship to a
variety of demographic, clinical, neurocognitive, and psychosocial variabl
es among a broad diagnostic sample of 211 adults with serious mental illnes
s. Participants completed a full battery of instruments measuring these var
iables. Results support a relationship between ratings of poor insight and
a psychotic (vs. mood) diagnosis, increased psychiatric symptoms, poorer so
cial skills, and negative medication attitudes. Minorities and those with a
substance abuse diagnosis were also more Likely to be rated as having poor
insight. No relationship was found between level of insight and age, gende
r, education level, neurocognitive deficits, hospitalization history, size
of one's social network, or quality of life measures. Results are discussed
in the context of improving the measurement and assessment of insight, con
ceptualizing interventions aimed at addressing level of insight, and improv
ing outcomes for patients with severe and persistent mental illness. Findin
gs also support a need for continued investigation of how mental illness is
understood, experienced, and expressed across diverse groups of people Liv
ing with mental illness.
