Note. CDI=Children’s Depression Inventory; MASC =Multidimensional Anxiety Scale for Children; ALEQ=Adolescent Life Events Questionnaire combined parent and child report; ALEQ scores were computed by averaging the number of parent and child reported life events in the previous 3 months and ranged from 1.50 to 31. Negative Bias combined sad and angry attention bias scores and Positive Bias score included happy attention bias scores.
