The Blood-Injection Symptom Scale (BISS): assessing a structure of phobic symptoms elicited by blood and injections.

Abstract

Assessments for blood-injury-injection phobia measure feared stimuli and overt behaviours, but they have not systematically addressed the symptoms of fear and faintness. The Blood-Injection Symptom Scale (BISS) was developed to overcome this omission. An exploratory factor analysis grouped symptoms triggered by blood and injections into three internally consistent factors (faintness, anxiety and tension). A confirmatory factor analysis replicated the factor structure in a new sample. To test the construct validity of the BISS, an attempt was made to reproduce Ost's (1992, Journal of Abnormal Psychology, 101, 68-74) finding that fear was stronger among people with concerns about injections, while faintness was stronger among people with concerns about blood. A community sample of 80 individuals with concerns (i.e. fear or fainting) about blood or injections completed the BISS. Controlling faintness, individuals with concerns about injections reported more fear than people with concerns about blood. In contrast, controlling for fear, the latter reported more symptoms of faintness. These data suggest that the BISS generates stable and internally consistent subscales useful in the measurement of symptoms elicited by blood and injections.
