Parenting Stress in Families of Children with Attention-Deficit/Hyperactivity Disorder: The Impact of ADHD Subtype and Oppositional Defiant Disorder Comorbidity

In this chapter, we present the results of a study designed to investigate: (a) the family relations of children with attention-deficit hyperactivity disorder (ADHD), (b) the sources of stress parents in families of children with this disorder experience and (c) the possible modulating role that ADHD subtype and comorbid oppositional defiant disorder (ODD) have on parenting stress level. One hundred and sixty seven families, divided into two groups, an ADHD group (N=114) and a control group (N=53), participated in the study. Parents of both groups completed a Semi-Structured Interview that gathered information on socio-demographics, family structure and the presence of oppositional behaviour symptoms, as well as the Parenting Stress Index Questionnaire (Abidin, 1990) to evaluate parent stress. The results showed that the relations of children with ADHD with their parents and siblings were significantly more tense than those of children without this disorder with their families. Parenting stress was higher in parents with ADHD children than in parents of non-ADHD children in most scales relating to parent personal variables, with even more sharp differences in measures of parenting stress that are triggered by the child's behaviour. Finally, our results evidenced how the ADHD subtype and ODD comorbidity influence the level of stress in parents. The results of the study suggest that interventions focused only on the behaviour of ADHD children are not likely to improve the developmental course of the disorder in the long run.
