The study investigated dimensionality in the Home and Community Social Behaviour Scales (HCSBS) that assess social competence (Peer Relations and Self-Management/Compliance) and antisocial behaviour (Defiant/Disruptive and Antisocial/Aggressive behaviour) in children and adolescents. The four scales comprising 64 items were completed by 551 parents of children aged 2-12 with emerging or present behavioural problems. Exploratory and confirmatory factor analyses were used to investigate the latent factor structure of the scales. The results revealed a meaningful three-factor solution for items within each of the following subscales: Peer Relations, Self-Management/Compliance, Defiant/Disruptive, and Antisocial/Aggressive. However, findings revealed some significant cross-loadings within each of the scales. Implications of the results are discussed.
