Assessing social competence and antisocial behaviors in children: item response theory analysis of the home and community social behavior scales

BACKGROUND: The Home and Community Social Behavior Scales (HCSBS) is a rating scale that assesses social competence and antisocial behavior among children and youths between ages 5–18. The present study aimed to investigate the psychometric properties of the HCSBS by applying item response theory (IRT). METHODS: The HCSBS was completed by parents of 551 Norwegian children refereed to three independent interventions towards problem behaviors. Data used in this study was collected before the interventions started. IRT was carried out in R version 4.0.0 to investigate HCSBS items, subscales and main scales. RESULTS: The results showed that the two-dimensional IRT models for social competence and antisocial behavior were the most appropriate. The measurement precision of the scales was high for a large range of the latent spectrum, and estimated reliabilities were satisfactory. Model evaluations indicated that the overall model fit for the scales were acceptable, but some misfit existed with respect to specific item pairs. CONCLUSION: The results indicate that the HCSBS is a reliable measurement instrument although there is still a potential for improvement by revising some of the items.
