One of the greatest challenges facing a society with a large number of orphans is to ensure that these children become well-adjusted and valuable members of society. However, there are a number of obstacles to achieving this outcome. Firstly, the psychological impact of parental and educator/role model illness and death on children should not be underestimated. There is good evidence to suggest that traditional mechanisms and strategies are coping well, but there is growing concern about the resilience of these systems. In addition there are reports that children cared for by extended family members or fostered out, are stigmatised and discriminated against - for example, they receive less food than other children and are given more chores. Other studies have found that children raised without sound role models are more likely to engage in delinquent behaviour with repercussions for society at large.
