Development and initial validation of an open-access online Behavioral Avoidance Test (BAT) for spider fear

Area of Science:

• Psychology
• Clinical Psychology
• Behavioral Science

Background:

• The behavioral avoidance test (BAT) is crucial for assessing fear by measuring avoidance behaviors.
• Variations in BAT protocols hinder result comparability and require extensive researcher preparation.
• An open-access online version, vBATon, was developed to address these limitations.

Purpose of the Study:

• To validate the efficacy of the online behavioral avoidance test (vBATon) in measuring avoidance behavior, anxiety, and disgust.
• To compare the vBATon's performance against a real-life BAT (rl-BAT).
• To assess the validity of vBATon by correlating its results with rl-BAT and self-report measures of spider fear.

Main Methods:

• Spider-fearful and nonfearful individuals (N=62) completed both a rl-BAT and vBATon within a week.
• Equivalence tests were used to compare vBATon and rl-BAT outcomes.
• Correlations were analyzed between vBATon, rl-BAT, and established spider fear questionnaires.

Main Results:

• Both rl-BAT and vBATon successfully differentiated between spider-fearful and nonfearful individuals.
• Equivalence tests confirmed vBATon's comparable performance to rl-BAT in capturing avoidance, anxiety, and disgust.
• vBATon showed moderate to high correlations with rl-BAT and self-report spider fear measures.

Conclusions:

• vBATon provides initial evidence of validity as a standardized, efficient, and user-friendly tool for measuring spider fear.
• The online test is a viable alternative to traditional rl-BATs for both research and clinical applications.
• vBATon facilitates more accessible and comparable assessments of phobic avoidance behaviors.
