Chronic Illness and Internalizing Symptomatology in a Transdiagnostic Clinical Sample of Youth

Abstract

Abstract Objective In research with community samples, children with chronic physical illnesses have shown elevated anxiety and depressive symptoms, compared to healthy peers. Less is known about whether physical illnesses are associated with elevated internalizing symptoms even among children referred for mental health treatment—a pattern that would indicate distinctive treatment needs among physically ill children receiving mental health care. We investigated the relationship between chronic physical illness and internalizing symptomatology among children enrolling in outpatient mental health treatment. Method A total of 262 treatment-seeking children ages 7–15 and their caregivers completed a demographic questionnaire, Child Behavior Checklist, and Youth Self-Report during a pre-treatment assessment. Physical illnesses were identified through caregiver report. Results There was no overall association between the presence/absence of chronic physical illness and parent- or child-reported symptoms. However, number of chronic physical illnesses was related to parent- and child-reported affective symptoms. Children with two or more chronic physical illnesses had more severe depressive symptoms than those with fewer physical illnesses. Conclusion Having multiple chronic illnesses may elevate children’s risk of depression symptomatology, even in comparison to other children seeking mental health care. This suggests a need to identify factors that may exacerbate depression symptoms in physically ill children who are initiating therapy and to determine whether different or more intensive services may be helpful for this group. The findings suggest the potential utility of screening for depression in youth with chronic physical illnesses, as well as addressing mental and physical health concerns during treatment.
