For example, in the case of panic disorder and agoraphobia, scales measure the frequency of panic attack symptoms, the severity of agoraphobic avoidance, and the extent to which the client is fearful of panic-related sensations (a hallmark feature of panic disorder).
The MI is a 29-item self-report instrument measuring the severity of behavioral avoidance [ 28, 29].
The Mobility Inventory for agoraphobia is a self-report instrument for measuring the severity of agoraphobic avoidance.
The Fear Questionnaire-agoraphobia subscale is a self-report instrument for measuring the severity of agoraphobic avoidance of five typical situations for agoraphobia.
The scale consists of five questions about frequency of anxiety, severity of anxiety, avoidance, interference with tasks and interference of social relationships.
Using a 5-point Likert scale from 1 (not at all) to 5 (extremely), responders rated the severity of intrusion, avoidance, and hyperarousal symptoms during the past 30 days.
Duration and severity of illness, avoidance of medication and desire to engage in a form of self-help, were cited as factors that motivated participants to complete the course.
Agoraphobic symptoms will be assessed with the Mobility Inventory (MI) [ 32], which is a 26-item self-report questionnaire that was designed to assess the severity of the avoidance of common agoraphobic situations.
Moreover, Nishimura et al. [ 8] investigated a potential relation between the frequency of panic attacks/agoraphobic avoidance and PFC activation during a cognitive task, indeed finding an association between altered activation patterns in the left inferior prefrontal cortex and panic attacks as well as between the anterior part of the right PFC and the severity of agoraphobic avoidance.
This instrument measures severity of fear and avoidance of phobic stimuli.
Finally the 15-item self-report version of the Fear Questionnaire (FQ) was used to measure severity of fear and avoidance [ 24].
