Quality of life and contact dermatitis: a disease-specific questionnaire

Contact dermatitis (CD) is a chronic disease with a significant impact on quality of life (QoL). There have been relatively few reports in the literature on specific QoL outcomes for patients suffering from CD.

To develop a new instrument specifically designed to measure QoL in CD and to investigate which disease features could strongly influence QoL.

Three hundred seventy-two patients affected by CD were administered a 20-item questionnaire, which comprised some questions taken and modified from the Dermatology Life Quality Index and the Skindex 16. Six more items were added. Univariate analysis and a chi-square test were performed.

Females reported lower QoL scores than males. Three aspects (itching, discomfort, and difficulty in daily activities) were strongly associated with a poor QoL; even if patients who experienced difficulty in using their hands at work had a poor QoL, the statistical significance was very low.

A CD-specific questionnaire can be used to understand a priori the impact on psychological behaviour of the patient and can lead to specific choices, such as the appropriate therapy to be used, the evaluation of treatment efficacy, the choice of preventive devices, and the comparison with QoL of other dermatoses.
