ObjectiveThis retrospective chart review examined a mediation model of parent and family functioning, childhood depression, and functional disability in youth with chronic headaches. Specifically, we evaluated whether depression mediates the relations between protective parenting and functional disability and between family functioning and functional disability.BackgroundChildren and adolescents with chronic and recurrent headache report elevated symptoms of depression. Children with chronic pain conditions, including chronic headaches, have also been found to originate from families with greater conflict, poorer cohesion, and lower organizational structure, and impaired family functioning is associated with greater disability in youth with chronic pain.MethodsThree hundred and eighty-two patients ages 5-17 years who underwent a multidisciplinary evaluation at a tertiary pediatric headache clinic were included in this study. Participants completed a pain intensity rating, the Children's Depression Inventory, and the Functional Disability Inventory. A parent completed the Family Relationship Index and the Adult Responses to Children's Symptoms questionnaires. Structural equation modeling was used to examine a mediation model and several alternative models.ResultsMediation was not supported, but an alternative model with both direct and indirect pathways provided excellent fit to the data: χ2(1) = 0.745, P = .39; comparative fit index = 1.00, root mean square error of approximation = 0.00 (CI: 0.00-0.17). Family functioning (β = -0.19, P < .01) and protective parenting (β = 0.17, P < .01) were associated with depression, but not disability. Depression was linked to disability (β = 0.24, P < .01). There was an indirect pathway from family functioning to depression to disability (β = -0.05, P < .05).ConclusionsFamily context is an important variable to consider in youth with chronic headaches and disability. While many studies have identified family functioning and depressive symptoms as separately linked to functional impairment, to our knowledge, we are the first to demonstrate depression as an intermediary variable between family dysfunction and disability within the pediatric headache population.© 2015 American Headache Society.
