The use of a psychological intervention to increase adherence during factor administration in a child with haemophilia.

While factor replacement treatments allow children with haemophilia to lead near normal lives, these treatments can be difficult to administer, especially to younger children. The intervenous infusions required by these treatments can be painful and result in children attempting to avoid treatment by exhibiting a range of inappropriate behaviours. Their children's uncooperative behaviour during prophylaxis was cited by parents as a significant barrier to treatment adherence. This study provides a case illustration of the use of psychological interventions to increase adherence during factor administration. Single-case methodology was used to demonstrate the effectiveness of the psychological interventions including counterconditioning, distraction, and positive differential reinforcement. The intervention resulted in increased adherence across several months of intervention. Psychological interventions can be effectively used by caregivers and care providers to increase adherence in the treatment of haemophilia.
