ious). In somatic symptom disorder, the empha sis is on maladaptive thoughts, feelings,
and behavior (e.g., an individual with angina  who worries constantly that she will have a
heart attack, takes her blood pressure multiple  times per day, and restricts her activities).
Illness anxiety disorder. Illness anxiety disorder is charac terized by high illness anxiety
that is distressing and/or disruptive to daily life with minimal somatic symptoms. The fo-
cus of clinical concern is the individual’s wo rry about having a disease; in most cases, no
serious disease is present. In psychological factors affecting other medical conditions, anx-
iety may be a relevant psychological factor affecting a medical condition, but the clinical
concern is the adverse effects on the medical condition.
