Somatizing patients present a history of vague, unexplained medical sy
mptoms. This study compared somatizing patients with pulmonary control
subjects by using the Diagnostic Interview Schedule (DIS-III-R), the
Illness Attitude Scales (IAS), and the Minnesota Multiphasic Personali
ty Inventory (MMPI-2). The groups differed in the number of somatizati
on symptoms reported and in the frequency of somatization disorder dia
gnoses when the screening criteria were used. The somatizing group obt
ained higher scores on the bodily preoccupation and hypochondriacal be
liefs subscales of the IAS; no differences were found on the MMPI-2. T
hese findings indicate that the DSM-III-R somatization screening items
can be useful for detecting somatization when patients present with u
nexplained respiratory complaints.
