ABSTRACT
Background:
Attention bias to threat is a fundamental transdiagnostic component and potential vulnerability factor for internalizing psychopathologies. However, the measurement of attentional bias, such as traditional scores from the dot-probe paradigm, evidence poor reliability and do not measure intra-individual variation in attentional bias.Methods:
The present study examined, in three independent samples, the psychometric properties of a novel attentional bias (AB) scoring method of the dot-probe task based on responses to individual trials. For six AB scores derived using the response-based approach, we assessed the internal consistency, test-retest reliability, familial associations, and external validity (using Social Anxiety Disorder, a disorder strongly associated with attentional bias to threatening faces).Results:
Compared to traditional AB scores, response-based scores had generally better internal consistency (range of Cronbach's alphas 0.68-0.92 vs. 0.41-0.71), higher test-retest reliabilities (range of Pearson's correlations 0.26-0.77 vs. -0.05-0.35), and were more strongly related in family members (range of ICCs 0.11-0.27 vs. 0-0.05). Furthermore, three response-based scores added incremental validity beyond traditional scores and gender in the external validators of current and lifetime Social Anxiety Disorder.Conclusions:
Findings indicate that response-based AB scores from the dot-probe task have better psychometric properties than traditional scores.
