The association of illness uncertainty to parent and youth adjustment in juvenile rheumatic diseases: effect of youth age.

Objective: : This study sought to examine the differential effect of youth age on the association between parental uncertainty and both parent distress and youth depressive symptoms within the context of juvenile rheumatic disease.

Methods: : The sample comprised 51 youth aged 9 to 17 years diagnosed with a juvenile rheumatic disease and their parents. Youth completed a measure of depressive symptoms (i.e., Children's Depression Inventory); parents completed measures of illness uncertainty (i.e., Parental Perceptions of Uncertainty Scale) and parental distress (i.e., Brief Symptom Inventory).

Results: : Parental uncertainty demonstrated a significant main effect on both parent distress and youth depressive symptoms. However, these main effects were qualified by significant parental uncertainty × youth age interactions. Parental uncertainty was significantly related to parent distress for both younger and older youth but was only significantly related to youth depressive symptoms in the sample of older youth.

Conclusions: : Parental uncertainty due to illness seems to be more predictive of both parent and youth distress with increasing youth age. These findings indicate that the impact of parental illness uncertainty on adjustment outcomes is pronounced as children transition into developmental periods of increasing autonomy and independence.
