Irritability in Children With ADHD and Emotion Dysregulation

The ABC is an instrument developed to assess emotional and behavioral difficulties in individuals with developmental disabilities. However, its irritability subscale (ABC-I) is a proven well-validated and widely used rating inventory for measuring irritability in neurotypical children. This subscale consists of 15 items about irritability, aggression, tantrums, agitation, and unstable mood.

The ARI was created as a dimensional measurement of irritability with both parent-report and self-report form. This questionnaire, assessing for symptoms of irritability in the previous 6 months, is composed of 6 items, and the 7th item on functional impairment is rated on a three-point scale (ranging from 0 for "not true" to 2 for "certainly true"). The reliability and validity of the ARI in typically developed children has been previously reported. The sum of scores of the first six items was used in this present study.

The SAICA was designed for children and adolescents aged 6-18 years, and provided a systematic evaluation of children's and adolescents' adaptive functioning. It assessed social adjustment in four major role areas: school, spare-time activities, peer relations, and home life. The scoring of each item ranges from 1 for positive/not a problem, to 4 for negative/severe problem. The children or adolescents with higher scores had either poorer functioning or more severe problems in the assessed domain.

The SDQ is a questionnaire for assessing the psychological problems and strengths in children, consisting of 25 items categorized as 5 subscales based on factor analyses: emotional symptoms, conduct problems, hyperactivity, peer problems, and prosocial behavior. An impact supplement added to the SDQ provides additional information on the target child's possible difficulties and the burden for others. Previous studies report that the Chinese version of the SDQ is a reliable and valid instrument for clinical studies in Taiwan.

The outcome measures for ERT cover percentage and number correct or incorrect and overall response latencies, which can be looked at either across individual emotions or across all emotions at once.

Outcome measures include the number of problems solved on first choice, mean choices to correct, mean latency (speed of response) to first choice and mean latency to correct. Each of these measures may be calculated for all problems, or for problems with a specified number of moves (one-move to five or six moves).

Outcome measures include errors (selecting boxes that have already been found to be empty and revisiting boxes which have already been found to contain a token) and strategy.
