A computer-based avatar task designed to assess behavioral inhibition extends to behavioral avoidance but not...

Area of Science:

• Psychology
• Clinical Psychology
• Psychometrics

Background:

• Avoidance is a core symptom in PTSD, anxiety, and depression, manifesting behaviorally and cognitively.
• Traditional self-report measures of avoidance are prone to response biases.
• The avatar task offers an objective assessment of behavioral inhibition (BI), a tendency to avoid novelty.

Purpose of the Study:

• To evaluate the avatar task's ability to measure cognitive and behavioral avoidance.
• To determine if the avatar task aligns with the Cognitive-Behavioral Avoidance Scale (CBAS).
• To investigate the avatar task's specificity for social versus non-social avoidance.

Main Methods:

• Participants completed the avatar task, the Harm Avoidance (HA) scale of the Tridimensional Personality Questionnaire (TPQ), and the CBAS.
• Correlational analyses examined relationships between avatar task scores and CBAS subscales (behavioral social, behavioral non-social, cognitive social, cognitive non-social).
• Median splits of avatar scores were used to compare behavioral and cognitive avoidance differences.

Main Results:

• Avatar task scores positively correlated with overall behavioral avoidance (CBAS total, BS, BN) but not cognitive avoidance (CS, CN).
• Social behavioral avoidance (BS) showed a stronger association with avatar task performance than non-social behavioral avoidance (BN).
• Avatar task performance differentiated behavioral avoidance but not cognitive avoidance.

Conclusions:

• The avatar task effectively measures behavioral avoidance, especially in social contexts.
• Findings support the avatar task as an objective tool for assessing behavioral avoidance relevant to PTSD and anxiety disorders.
• Future research could adapt the avatar task to objectively measure cognitive avoidance.
