Characteristics of Blood-Injection-Injury Fears in People Receiving Intravenous Chemotherapy

Blood-Injection-Injury (BII) phobia is associated with distress and avoidance in response to blood, injury, or receiving injections. BII phobia can therefore create problems for those receiving medical procedures such as chemotherapy. The prevalence rate of BII in the general population has been estimated to be less than 5% but as many as 19% of outpatients receiving chemotherapy surveyed by Carey and Harris (Behaviour Change 22:5–90, 2005) reported BII concerns. This study examined the extent and characteristics of BII concerns among outpatients receiving chemotherapy for the first time (n = 124). Almost 17% of the sample had scores on the Mutilation Questionnaire comparable to samples with clinical BII phobia. Those assigned to a high BII concern group based on Mutilation Questionnaire scores reported higher somatic and fainting responses to BII stimuli and elevated disgust sensitivity, compared to groups selected for low BII concerns. Females had significantly higher Mutilation Questionnaire scores than males. Thus, the BII concerns of outpatients receiving chemotherapy appear qualitatively similar to the concerns reported by clinical BII phobia samples and analogue student samples. We suggest that the standard inclusion of a brief, reliable screening measure of BII concerns for outpatients scheduled for chemotherapy, coupled with brief, effective interventions to reduce BII-related distress, may be warranted.
