Mas et. al

• Mas et. al had three aims:

  • The first aim was to see if the BIPI could distinguish between people who had the BII phobia and those who didn't.
  • They also wanted to see if the BII phobia was a one-dimensional phobia or if it was influenced by a range of factors.
  • They also wanted to see if the BIPI was sensitive to changes in people with the phobia.
• 39 participants were used who had been diagnosed BII phobia.
• The control group was matched based on age and gender.
• The participants took the fear questionnaire to measure their agoraphobic fear, social anxiety, and blood-injection-injury phobia.
• Results showed that:

  • The BIPI was very reliable and had good concurrent validity with the score on the FQ.
  • The BIPI was also able to distinguish between people who had the BII phobia and those who didn't.
  • They also found that the BIPI was very sensitive at catching therapeutic improvement. Participants did the BIPI before and after going to therapy and the BIPI noticed a reduction in the phobia severity after the treatment.
