Contact dermatitis is a prevalent condition that has a significant impact on quality of life (QoL). Although many generic dermatological QoL instruments exist, none were developed by and for patients with allergic contact dermatitis (ACD).
The aim of the study was to create and validate a reliable QoL instrument specific for the ACD population.
We identified QoL items specific to ACD through a series of qualitative interviews with ACD patients and experts. We created a 17-question survey that queries the patient across the following 3 major domains: symptoms, functioning, and emotions. We used statistical methods to evaluate the reliability and validity of this tool.
Ninety patients with relevant positive results on patch testing completed the novel ACD instrument and the Skindex-29. This instrument exhibited reliability and validity in individuals with ACD and was more sensitive than the generic tool Skindex-29.
This novel instrument is the first tool developed specifically to assess the unique impacts of ACD on QoL. Providers can reliably use this index to assess the specific aspects of the disease most problematic for the ACD patient and use this information to more properly inform counseling and management.
