Deception in Children With and Without Severe Conduct Problems

Deception is not only part of daily life for adults, but it is also part of typical development throughout childhood. Research has shown that the ability to deceive improves with age and has been found to be related to the development of cognitive skills such as executive functioning processes, theory of mind, and intelligence. However for some children, lie-telling becomes problematic and atypical. For children with conduct problems, deception is one of the most common presenting symptoms and has been found to be pervasive across childhood and into adolescence. While most studies analyze the lying behaviours of these children based on parent and teacher reports, no studies have yet empirically evaluated the actual deceptive behaviours of children with severe conduct problems. The current study investigated the antisocial and prosocial deception rates and abilities of children with and without severe conduct problems. Additionally, cognitive measures and parental reports of lying and parenting styles were considered in order to determine how such variables may be related to deception. A total of 66 children participated in the current study with half of the sample originating from a community agency for children with behaviour problems and the other half consisting of an age- and gender-matched control sample. Results demonstrated that compared to their typically developing counterparts, children with conduct problems were more likely to behave antisocially by committing antisocial transgressions, and subsequently lying. These children were also less likely to tell prosocial lies. Consistent with previous research, many cognitive measures, such as Executive Functioning (e.g., inhibition) and Theory of Mind (1st and 2nd Order) were found to be related to deception for the typically developing sample, though fewer and different cognitive measures were found to be predictive of deception within the clinical sample. Parent ratings of lie-telling frequency were not predictive of antisocial or prosocial deception, though they were predictive of antisocial lie-telling sophistication. Parenting styles were minimally predictive of deception. Results suggest that the mechanisms used by children with conduct problems during deception differ from a typically developing sample. Limitations as well as implications are discussed.Ph
