Cluster Dendrogram of Irritability Factor and Related Scales. Edge probability values (%) are approximate unbiased (au) estimates by multiscale bootstrapping (Shimodaira, 2004). Measures or lusters with a 95% or greater probability of grouping together are supported by the data, indicated by red boxes to reflect maximally inclusive groupings. Irritability=Irritability Factor from bifactor analysis; RPQ=Reactive and Proactive Aggression Questionnaire; DASS = Depression, Anxiety, and Stress Scale; AQ=Aggression Questionnaire.
