Aims: We aim to examine the relationship between child behavioural problems and several parental factors, particularly parental behaviours as reported by both mothers and fathers in a sample of preschool children in Sweden. Methods: Participants were mothers and fathers of 504 3- to 5-year-olds that were recruited through preschools. They completed a set of questionnaires including the Eyberg Child Behavior Inventory, Parenting Sense of Competence Scale, Parenting Scale, Parent Problem Checklist, Dyadic Adjustment Scale and Depression Anxiety Stress Scale. Results: Correlational analyses showed that parent-reported child behaviour problems were positively associated with ineffective parenting practices and interparental conflicts and negatively related to parental competence. Regression analyses showed that, for both mothers and fathers, higher levels of parental over-reactivity and interparental conflict over child-rearing issues and lower levels of parental satisfaction were the most salient factors in predicting their reports of disruptive child behaviour. Conclusions: This study revealed that Swedish parents’ perceptions of their parenting is related to their ratings of child behaviour problems which therefore implies that parent training programs can be useful in addressing behavioural problems in Swedish children.
