<unk>  is the fear of being closed into a small space. It is typically classified as an anxiety disorder and often results in a rather severe panic attack. It is also confused sometimes with Cleithrophobia (the fear of being trapped). Diagnosis of<unk>  usually transpires from a consultation about other anxiety-related conditions. Certain criteria have to be met to be diagnosed with specific phobias. This criteria includes: * an interminable obstructive or excessive fear caused by the existence or anticipation of a specific situation * anxiety response when stimulus is exhibited; can result in panic attacks in adults or, for children, an outburst, clinging, crying, etc. * acknowledgment by adult patients that their fear stems from the anticipated threat or danger * engaging in procedures to evade dreaded object or situation, or proneness to face the situation but with discomfort or anxiety * the person's evasion of the object or situation impedes with everyday life and relationships * the phobia is continuous, usually for 6 months or longer * symptoms cannot be ascribed to other underlying mental conditions, such as obsessive-compulsive disorder (OCD) or post-traumatic stress disorder (PTSD) Scale This method was developed in 1979 by interpreting the files of patients diagnosed with<unk>  and by reading various scientific articles about the diagnosis of the disorder. Once an initial scale was developed, it was tested and sharpened by several experts in the field. Today, it consists of 20 questions that determine anxiety levels and desire to avoid certain situations. Several studies have proved this scale to be effective in<unk>  diagnosis. Questionnaire This method was developed by Rachman and Taylor, two experts in the field, in 1993. This method is effective in distinguishing symptoms stemming from fear of suffocation. In 2001, it was modified from 36 to 24 items by another group of field experts. This study has also been proven very effective by various studies.
