Panic Disorder 307
is approximately 28, with posttreatment scores dropping to 19 (e.g., D. M. Clark et al.,
1994).
Body Sensations Questionnaire
The Body Sensations Questionnaire (BSQ) is a 17-item questionnaire also developed by
Chambless et al. (1984) to assess intensity of fear associated with physical symptoms of
arousal (Antony, 2001a). The BSQ and ACQ are normally administered together and
both have been used extensively in the research literature. Individuals with agoraphobia
or panic disorder score significantly higher on the BSQ (Chambless & Gracely, 1989)
with panic disorder samples (M = 46.3; SD = 8.7) scoring significantly higher than
healthy (M = 28.4, SD = 6.5) controls (e.g., Kroeze & van den Hout, 2000b). The BSQ
also is sensitive to treatment effects, with posttreatment scores dropping within the
normal range (i.e., D. M. Clark et al., 1994). The clinician will find the ACQ useful for
assessing exaggerated threat appraisals of physical symptoms and the BSQ useful for
assessing fear of panic- relevant bodily sensations. A copy of both measures can be found
in Antony (2001a, Appendix B).
Mobility Inventory for Agoraphobia
The Mobility Inventory for Agoraphobia (MI) is a self- report questionnaire that assesses
the severity of agoraphobic avoidance, frequency of panic attacks, and size of safety
zone (Chambless, Caputo, Jasin, Gracely, & Williams, 1985). The first section of the
questionnaire lists 26 situations often avoided in agoraphobia and individuals rate the
extent of avoidance of each situation on a 5-point scale (1 = “never avoid”; 5 = “always
avoid”) when accompanied and when alone. They then circle the five situations that
cause the greatest amount of concern or impairment. The most recent version of the MI
also instructs individuals to indicate the frequency of panic attacks in the past 7 days as
well as in the past 3 weeks, and to rate the severity of their panic attacks on a 1 (“very
mild”) to 5 (“extremely severe”) scale (see Antony, 2001b). The modified MI added
a fourth section in which individuals report on the location and size of their safety
zone. Most research on the MI has focused on the first section of the questionnaire in
which two summed scores are calculated, an Avoidance Accompanied and an Avoid-
ance Alone score.
Individuals with agoraphobia score significantly higher on the MI Avoidance Alone
and Avoidance Accompanied subscales than do those with other anxiety disorders and
nonclinical controls (Chambless et al., 1985; Craske et al., 1986) and the factorial struc-
ture of the MI showed high stability over a 5-year period (Rodriguez, Pagano, & Keller,
2007). For the clinician the MI yields valuable information on the nature and extent of
agoraphobic avoidance often associated with panic disorder. The original MI was repro-
duced in an appendix of Chambless et al. (1985) and the modified MI can be found in
Antony (2001b, Appendix B).
Albany Panic and Phobia Questionnaire
The Albany Panic and Phobia Questionnaire (APPQ) is a 27-item questionnaire that
assesses level of fear (0–8 scale) associated with physical and social activities that pro-
