Validating a mobile eye tracking measure of integrated attention bias and interpretation bias in youth.

INTRODUCTION: This study sought to validate a real-world speech task designed to assess attention and interpretation bias in an integrated and ecologically valid manner.
METHODS: Thirty adolescent girls gave a speech in front of an emotionally ambiguous judge and a positive judge while wearing mobile eye tracking glasses to assess how long they looked at each judge (i.e., attention bias). They also reported their interpretations of the ambiguous judge and distress associated with the task (i.e., interpretation bias).
RESULTS: These task-based measures correlated with self-report of interpretation bias and mother-report of attentional control, demonstrating convergent validity. They did not correlate with frustration or high intensity pleasure, indicating discriminant validity. Task-based measures of interpretation bias also showed predictive and incremental validity in relation to child distress during the speech. DISCUSSION: This proof-of-concept study demonstrates the initial validity of a novel task designed to assess attention and interpretation bias as they manifest in real-world social interactions.
