    Abstract:
    To understand the development of dental anxiety better and to identify those at increased risk of developing dental anxiety, the Level of Exposure-Dental Experiences Questionnaire (LOE-DEQ) was developed. The aim of the current study was to determine the psychometric properties (i.e. factor structure, reliability, and validity) of the LOE-DEQ and to determine its suitability as an additional screening instrument for dentally anxious patients. Five different samples were used: (i) highly dentally anxious patients (n = 119); (ii) general dental patients (n = 480); (iii) students (n = 186); (iv) psychiatric outpatients (n = 17); and (v) oral surgery patients (n = 34). Results of the factor analysis revealed a four-factor solution. The LOE-DEQ has sufficient internal consistency (Cronbach's alpha values ranging from 0.69 to 0.85) and satisfactory test-retest reliability (intraclass correlation coefficient = 0.78). The results further suggest that this instrument has adequate discriminant, concurrent, and predictive validity. It is concluded that the LOE-DEQ is a useful tool for assessing patients' background in terms of previous exposure to distressing dental events, which is considered a vulnerability factor in the development of dental anxiety.
