The Legacy of Mental Distress Following Physical Illness in Childhood: Findings From the Australian Temperament Project

Abstract

Abstract Objective Childhood physical illnesses have been associated with heightened risk for mental health problems in adolescence and young adulthood; however, little is known about the natural history of this relationship. Here, we examine the nature of mental health adjustment to illness from diagnosis in childhood into adolescence and young adult life. Methods Data were drawn from a large population-based cohort. Parents reported whether their child had a physical illness at 5–6 and 7–8 years and whether they believed their child was so sick it was thought they might die. Depression and anxiety symptoms were reported by parents (for children 7–10 years) and self-reports (11–28 years). Results A total of 1,001 (56%) parents reported their child had a physical illness. Of these parents, 143 (8%) believed their child might die. Findings indicated there was some evidence of higher levels of depressive and anxious symptoms across late childhood and into early adolescence for those reporting a physical illness in childhood. A similar pattern was observed for those who were so sick it was thought they might die, although symptoms were elevated to a greater extent. Conclusion Although physical illness in middle childhood is associated with higher levels of depressive and anxious symptoms, by early adolescence, these differences diminish, indicating a process of adaptation that persists into young adulthood. This suggests a potentially sensitive period of adjustment to illness for some, especially for children who it was feared might die. Additional psychosocial assessment and support may be warranted across the “acute” illness period.
