The ABC
Items are scored in five subscales: Irritability, Lethargy/Social Withdrawal, Stereotypic Behavior, Hyperactivity/Non-compliance, and Inappropriate speech. Internal consistency was reported as good by Karabekiroglu and Aman [50] (Cronbach’s alphas from 0.68 to 0.90) and by Kaat, Lecavalier and Aman [66] (alphas from.77 to.94). Inter-rater reliability (between similar raters) and test-retest reliability were not assessed. Brinkley et al. [64] and Kaat, Lecavalier and Aman [66] demonstrated that the ABC had good structural validity; the latter very large study (n = 1893) found that 90% of items matched the standard ABC factor structure, though the model fit was ‘marginal’ (Root Mean Square Error of Approximation (RMSEA) was .086). Sigafoos et al. [73] also showed that the ABC had good structural validity with five factors, though due to the small sample size (n = 32), the Sigafoos paper was judged to be of poor methodological quality. Karabekiroglu and Aman [50] showed that the ABC distinguished between clinical subgroups. Kaat, Lecavalier and Aman [66] found, as expected, that irritability and hyperactivity decreased with age. Kaat, Lecavalier and Aman [66] and Karabekiroglu and Aman [50] found predicted significant correlations with related constructs measured by the Child Behaviour Checklist and the Autism Behaviour Checklist, and Kuhlthau et al. [67] with a measure of child quality of life, the Child Health and Illness Profile—Child Edition.
