      Abstract

      Background:Vitiligo is an important skin disease that can alter individual self-image and thus have major impact on the quality of life.Aims:The objective of this study was to translate and to test the reliability and validity of the 10-item Dermatology Life Quality Index (DLQI) questionnaire in Tunisian vitiliginous patients.Methods:Using a standard “forward-backward” translation procedure, the English language version of the questionnaire was translated into Persian (the Iranian official language) by two bilinguals. Seventy patients with vitiligo attending the Department of Dermatology, Regional Hospital, Medenine, Tunisia, were enrolled in this study. The reliability and internal consistency of the questionnaire were assessed by Cronbach's α coefficient and Spearman's correlation, respectively. Validity was performed using convergent validity.Results:In all, 70 people entered into the study. The mean age of respondents was 28.3 (SD=11.09) years. Scores on the DLQI ranged from 0 to 24 (mean ± SD, 7.05 ± 5.13). Reliability analysis showed satisfactory result (Cronbach's α coefficient=0.77). There were no statistically significant differences between daily activity (DA) and personal relationship (PR) scale mean scores in generalized versus focal-segmental involvement in sufferers (P = 0.056, P = 0.053, respectively). There were also strong differences between the mean scores of the PR scale with the involvement of covered only and covered/uncovered areas (P = 0.016) that was statistically significant in the second group.Conclusions:The study findings showed that the Tunisian version of the DLQI questionnaire has a good structural characteristic and is a reliable and valid instrument that can be used for measuring the effects of vitiligo on quality of life.

      Dermatology Life Quality Index (DLQI)--a simple practical measure for routine clinical use.

       Korsa Khan,  A. Finlay (1994)
      A simple practical questionnaire technique for routine clinical use, the Dermatology Life Quality Index (DLQI) is described. One hundred and twenty patients with different skin diseases were asked about the impact of their disease and its treatment on their lives; a questionnaire, the DLQI, was developed based on their answers. The DLQI was then completed by 200 consecutive new patients attending a dermatology clinic. This study confirmed that atopic eczema, psoriasis and generalized pruritus have a greater impact on quality of life than acne, basal cell carcinomas and viral warts. The DLQI was also completed by 100 healthy volunteers; their mean score was very low (1.6%, s.d. 3.5) compared with the mean score for the dermatology patients (24.2%, s.d. 20.9). The reliability of the DLQI was examined in 53 patients using a 1 week test-retest method and reliability was found to be high (gamma s = 0.99).

        Translating health status questionnaires and evaluating their quality: the IQOLA Project approach. International Quality of Life Assessment.

        This article describes the methods adopted by the International Quality of Life Assessment (IQOLA) project to translate the SF-36 Health Survey. Translation methods included the production of forward and backward translations, use of difficulty and quality ratings, pilot testing, and cross-cultural comparison of the translation work. Experience to date suggests that the SF-36 can be adapted for use in other countries with relatively minor changes to the content of the form, providing support for the use of these translations in multinational clinical trials and other studies. The most difficult items to translate were physical functioning items, which used examples of activities and distances that are not common outside of the United States; items that used colloquial expressions such as pep or blue; and the social functioning items. Quality ratings were uniformly high across countries. While the IQOLA approach to translation and validation was developed for use with the SF-36, it is applicable to other translation efforts.

          The relationship between stress and the onset and exacerbation of psoriasis and other skin conditions.

          The role of stressful life events in the progress of various skin conditions was studied retrospectively in patients who presented with either psoriasis (where there is some agreement about the importance of stress), urticaria, acne, alopecia and non-atopic eczema (where there is some uncertainty regarding the role of stress), or malignant melanoma, fungal infection, basal cell carcinoma and melanocytic naevi (where stress is considered less relevant). When patients in the three groups were matched for age, those with psoriasis were more likely to report that the experience of stress pre-dated the onset and exacerbations of their condition than patients with other skin diseases. For the psoriasis patients the most common types of life events were family upsets (such as bereavements), and work or school demands, but chronic difficulties were also common. There was no relationship between the severity of stress and time to onset or exacerbations. The results support the notion that stress is more likely to be associated with the onset of psoriasis than other conditions, but also that there may be considerable individual variation in the ability to cope, suggesting that psychological interventions may be helpful for particular patients.
