Why would the reasons for attrition rates be different for children and for adults?
What will be an ideal response?
Attrition by children is more likely to be associated with family dynamics (e.g., the family moves, the parent(s) grow tired of participation), with children being less able to control family events. On the other hand, attrition in adults might be due to more active choices not to participate; for older participants, death may be a significant source of attrition.
