Behavioural Problems and Competences in 4-year-olds: Dimensions and Relationships
The study explored the dimensionality of parental ratings of positive and negative aspects of behaviour in a sample of 4-year-olds (n = 377). The children were described using the Preschool Behaviour Questionnaire (PBQ) with items added to include ego strength/effectance and social competence. Factor analytic results showed a 2-factor structure in the PBQ behaviour problem area: factor 1 describing externalised conduct behaviour problems; and factor 2 encompassing the internalised anxious-fearful problems. Factor analysis of both positive and negative behavioural aspects yielded a 3-factor structure with externalised problem behaviours as the first factor, a second broad social inhibition factor, and an ego strength/effectance factor. Correlations showed a low positive relationship between the two problem areas; a stronger relationship was found between the positive aspects, peer competence, and ego strength/effectance. There was a weak significant negative correlation between peer competence behaviours and outgoing conduct problems. Peer competence was more strongly negatively related to anxiousfearful behaviour problems. Conceptual and methodological aspects were discussed and the results were related to the inhibition-disinhibition construct in temperament research.
