Official Title: Effectiveness of a Knowledge-based Intervention for Patients With Cutaneous Lupus Erythematosus

Brief Summary: Studies have shown that there are significant differences in severity and outcome of lupus in patients of colored skin compared with Caucasians. There are many factors that lead to this discrepancy: genetics, poverty, education level, as well as behavioral and cultural factors. Cutaneous Lupus Erythematosus (CLE) is a disease of flares and remissions with identifiable triggers. One of the most aggravating triggers in CLE is sun exposure. The investigators hypothesize that there are disparities in knowledge about photoprotection, leading to poorer outcomes in minority ethnic groups. This study aims to assess knowledge of risk factors and triggers, especially sun exposure, and the effects on quality of life of Caucasian and minority populations, by conducting an assessment survey and subsequent teaching intervention on appropriate skin protection techniques including appropriate sun screen application, and use of sun-protective clothing. After three months a survey to evaluate knowledge retention about and the application of the educational intervention will be conducted.

Sponsor: Northwestern University

Current Primary Outcome: Percentage of Subjects Who Correctly Answered a Knowledge Assessment Item Immediately Before and After an Educational Lecture [ Time Frame: immediately before and after an educational lecture ]

In order to evaluate the immediate effect of an educational lecture about cutaneous lupus erythematosus (CLE) and sun protection, subjects completed a written questionnaire to assess knowledge about CLE and sun protection immediately before and after the educational lecture. The percentage of subjects who correctly answered a knowledge assessment item were calculated pre- and post-educational lecture.


Original Primary Outcome: Does an interventional intervention impact immediate post-intervention knowledge [ Time Frame: 0 hours ]

Immediately after the educational intervention delivered by study personnel on Cutaneous lupus and sun exposure, the subject will be asked to complete a questionnaire which will be used to assess the immediate effect of the educational intervention on the subject's knowledge of sun exposure's effects on Cutaneous lupus.


Current Secondary Outcome: Percentage of Subjects Who Correctly Answered a Knowledge or Behavioral Assessment Item Before and 3 Months After an Educational Lecture [ Time Frame: before and 3 months after an educational lecture ]

In order to evaluate the long-term effect of an educational lecture about cutaneous lupus erythematosus (CLE) and sun protection, subjects completed a questionnaire to assess knowledge about CLE and sun protection behaviors immediately before and three months after an educational lecture. The percentage of subjects who correctly answered a knowledge or behavioral assessment item were calculated pre- and three months post-educational lecture.


Original Secondary Outcome: Does an education intervention impact long term knowledge? [ Time Frame: 3 months ]

Three months after the initial visit, the study personnel will call the subject and obtain answers to a subsequent questionnaire.
