Mm. Antony et al., ILLNESS INTRUSIVENESS IN INDIVIDUALS WITH PANIC DISORDER, OBSESSIVE-COMPULSIVE DISORDER, OR SOCIAL PHOBIA, The Journal of nervous and mental disease, 186(5), 1998, pp. 311-315
To measure the extent to which anxiety disorders interfere with variou
s domains of functioning, the Illness Intrusiveness Ratings Scale (IIR
S) was completed by individuals with a DSM-IV principal diagnosis of p
anic disorder (PD; N = 35), obsessive-compulsive disorder (OCD; N = 51
), or social phobia (SP; N = 49). Although the three groups did not di
ffer on total IIRS scores, group differences did emerge for particular
domains of functioning. Patients with OCD reported significantly more
interference with respect to passive recreation (e.g., reading) than
did SP patients and with respect to religious expression compared with
both PD and SP patients. Patients with SP reported more impairment wi
th respect to social relationships and self-expression/self-improvemen
t, compared with the other two groups. When compared with populations
with a variety of other chronic illnesses, patients in the present stu
dy reported much higher levels of illness intrusiveness. The implicati
ons of these findings and future directions for research are discussed
.
