The present study examined the relationship between marital conflict, parenting conflict and emotional and behavioural problems in children aged 2 to 16 years. Additionally the psychometric properties of the Parent Problem Checklist (PPC; Dadds & Powell, 1991) were examined in sample of 200 parents sharing the role of parenting. The purpose of the present study was threefold: (1) to gain a measure of parenting conflict and children’s behavioural and emotional problems in a non-clinic referred community sample, (2) to examine the individual contribution of conflict specific to child-rearing to the prediction of child problems, and (3) to further validate the psychometric properties and examine the factor structure of the Parent Problem Checklist (PPC; Dadds & Powell, 1991). Findings support the hypothesis that parenting conflict influences children’s outcomes more than either general marital conflict or marital satisfaction. Analyses of the PPC show evidence of strong reliability and validity for the measure and factor analysis provided support for a two-factor structure. Implications for clinical practice and understanding the role of parenting conflict in the development of child difficulty are discussed.
