Design outcomes

Primary

Measure	Time frame
1. Social anxiety symptoms (reported by children) are measured using the Social Anxiety Scale for Children – Revised and the the social phobia subscale of the SCARED-NL-71 at baseline (pre-training), 3 (post-training) and 10 weeks (follow up) 2. Social anxiety symptoms (reported by one of the parents and the teacher) are measured using the Social Anxiety Scale for Children – Revised and the social phobia subscale of the SCARED-NL-71 at baseline, 3 and 10 weeks 3. Interpretation bias is measured with the Ambiguous Scenarios Task (AST) and the Interpretation Recognition Task (IREC-T) at baseline, 3 and 10 weeks	—

Secondary

Measure	Time frame
1. State anxiety during the training as measured with a state anxiety list at baseline, 3 and 10 weeks 2. Interference and attention bias as measured with the original STROOP and an Emotional STROOP tests at baseline, 3 and 10 weeks 3. Total level of anxiety is measured with the SCARED 41 questionnaire at baseline, 3 and 10 weeks 4.Aggression is measured with the Reactive-Proactive aggression scale (RPQ) at baseline, 3 and 10 weeks 5. Attention control is measured with the Attention Control Scale (ACS) at baseline, 3 and 10 weeks 6. Motivation to partake in the training and to change social anxiety symptoms are measured using interview questions at baseline, 3 and 10 weeks	—
