Creating a Computerized Instrument for the Assessment of Blood-Injury-Injection Phobia.

Area of Science:

• Psychology
• Clinical Psychology
• Behavioral Science

Background:

• Blood-injury-injection phobia (BII) is a specific phobia that can be debilitating.
• Traditional assessment methods for BII phobia can be time-consuming and subjective.
• Digital media, such as images and videos, can elicit anxiety responses relevant to phobia assessment.

Purpose of the Study:

• To introduce and evaluate a new computerized instrument, the Multimedia Behavioral Avoidance Test (MBAT), for assessing BII phobia.
• To compare the MBAT's effectiveness with existing pencil-and-paper questionnaires.
• To assess the reliability and validity of the MBAT in a clinical population.

Main Methods:

• The MBAT utilized 30 original images and 30 videos related to blood, injury, and injections presented via computer.
• Subjective anxiety responses and time latency were recorded for each participant.
• The MBAT's results were compared with standard BII phobia questionnaires, and heart rate was measured using a pulsioximeter.

Main Results:

• The MBAT demonstrated high internal consistency for both image and video components (α = .98).
• The instrument showed high concurrent validity (r = .78 to .85) when compared to established anxiety scales.
• The MBAT successfully identified 12 participants with potential BII phobia.

Conclusions:

• The MBAT is a reliable and valid tool for assessing BII phobia.
• It offers a more objective, efficient, and user-friendly alternative to traditional assessment methods.
• The MBAT can aid in planning subsequent exposure therapy using digital stimuli.
