Strengths and difficulties

Strengths and Difficulties Questionnaire - child version (SDQ; Goodman, 1997). It is a 25-item on a three-point Liker scale, from 0 "not true" to 2 "certainly true" where lower scores represent an improvement or lack of problems.

Emotional symptoms

The Child Behavior Checklist for ages 6-18 (CBCL; Achenbach \& Rescorla, 2001) is a parent-report of child emotional and behavioral problems. Each item is rated on a 3-point Likert-style scale ranging from 0 (not true) to 2 (very true or often true). The DSM-derived affective and anxiety scales and the anxious/depressed and withdrawn/depressed syndrome scales, respectively, will be used to assess emotional symptoms.
