Multigroup multilevel structure of the child and parent versions of the Positive and Negative Affect Schedule (PANAS) in adolescents with and without ADHD.

= 139) ADHD. A 3-factor (Positive Affect, Fear, Distress) within and a 2-factor (Positive Affect, Negative Affect) between model was found to be best fitting using both parent and adolescent reports. The model demonstrated configural invariance for the adolescent report and scalar invariance for the parent report. These results support the multidimensionality of negative affect in youth with ADHD, even when assessed via the short-version PANAS-C. In future work, it will be important to consider the implications of more discrete types of negative affect expression (fear and distress) found across time at the individual level for assessment and intervention practice.
