Note: THT_PsyNeuro = threat sensitivity assessed using neurophysiological and self-report indicators; DIS_PsyNeuro = weak response inhibition assessed using neurophysiological and self-report indicators; THT_PsyNeuro x DIS_PsyNeuro Product = interaction term, computed as the product of mean-centered scores for THT_PsyNeuro and DIS_PsyNeuro; r = Pearson correlation coefficient (indexing manifest-score associations); β = standardized regression coefficient; R = multiple regression coefficient; Change R² = incremental variance accounted for by including the THT_PsyNeuro x DIS_PsyNeuro interaction term. OCD = Obsessive Compulsive Disorder; GAD = Generalized Anxiety Disorder; PTSD = Posttraumatic Stress Disorder.
