| The utility, validity, and reliability of a structured play task, coding system, and self-report questionnaires were evaluated to develop the procedures necessary to investigate sibling relations and parental intervention into sibling conflict in families of children with and without ADHD. Preliminary comparisons were also conducted on these dimensions between 7 families with a child with ADHD and 7 families of children without. In each family 1 parent and 2 children (older child aged 8-12 years, younger child aged 4-9 years) participated. An observational car-race task used was found to be developmentally inappropriate for this population. A global coding scheme possessed greater interrater reliability than a micro-analytic scheme. A sibling relations questionnaire with previously reported validation data reliably differentiated groups, while a parental intervention questionnaire without, did not. Parents of children with ADHD reported using parent-centred strategies in response to sibling conflict more often than did parents of children without ADHD. |
