A dimensional analysis of claustrophobia

The present study investigated whether situational and cognitive dimensions of claustrophobia exist. To this end, the Claustrophobia Situations Questionnaire (CSQ) and the Claustrophobia General Cognitions Questionnaire (CGCQ) were developed and exploratory factor analyses were performed on these scales. Two-factor solutions for both the anxiety and the avoidance ratings on the CSQ were obtained, accounting for 40.1% and 34.2% of the variance, respectively. Two subscales were created from the two-factor solution of the anxiety section of the CSQ: (1) Fear of Entrapment and (2) Fear of Physical Confinement. Two subscales were also created from the two-factor solution of the avoidance section of the CSQ: (1) Avoidance of Crowds and (2) Avoidance of Physical Confinement. A three-factor solution was obtained for the CGCQ, accounting for 54.4% of the variance, from which the following three subscales were created: (1) Fear of Loss of Control, (2) Fear of Suffocation, and (3) Fear of Inability to Escape. Cronbach alphas for all subscales ranged from .84 to .94. Exploratory correlational analyses were conducted between the situational and the cognitive dimensions.
