“…The sum of the scores provides a value between 0 (no involvement) and 30 (maximum impact on the HRQoL of the patient). The questions are easily understood, with an average completion time of 2 min (Loo et al, 2003), and fit onto a single side of A4 paper (30 Â 21 cm). The DLQI measurement properties have been established over the last 10 y ( Lewis and Finlay, 2004).…”

This study's aim was to determine the relationship between Dermatology Life Quality Index (DLQI) scores and a Global Question (GQ) concerning patients' views of the overall impairment of their skin-related quality of life (QoL), and to express this relationship by identifying bands of DLQI scores equivalent to each GQ descriptor. A DLQI questionnaire and the GQ were mailed to 3834 adult general dermatology outpatients. There were 1993 (52%) responses: male 841; female 1152. Mean DLQI score = 4.86 (range 0-30, standard deviation (SD) = 5.83). Mean GQ score = 1.22 (range 0-4, SD = 1.20). The mean, mode, and median of the GQ scores for each DLQI score were used to devise several sets of bands of DLQI scores, and kappa coefficients of agreement calculated. The set proposed for adoption is: DLQI scores 0-1 = no effect on patient's life (GQ = 0, n = 754); DLQI scores 2-5 = small effect on patient's life (GQ = 1, n = 611); DLQI scores 6-10 = moderate effect on patient's life (GQ = 2, n = 327); DLQI scores 11-20 = very large effect on patient's life (GQ = 3, n = 242); DLQI scores 21-30 = extremely large effect on patient's life (GQ = 4, n = 59); kappa coefficient 0.489. Banding of the DLQI will aid the clinical interpretation of an individual's DLQI score and allow DLQI scores to inform clinical decisions.

“…Other general health measures that have been used in comparison with the DLQI are willingness to pay (Lundberg et al, 1999) and total illness burden (Fivenson D et al, 2002). An illustrated version of the DLQI (Loo et al, 2003) has been evaluated, but it was not possible to demonstrate exact equivalence to the text only version.…”

“…This simple, validated and widely used 10-question instrument is scored from a minimum of 0 to a maximum of 30 [5, 6]. The DLQI is easily completed with an average completion time of 2 min [7]. The questionnaire was printed on light blue paper to help increase response rates [8].…”

Objective: To explore whether clinicians used formal quality of life (QoL) information if provided by patients completing the Dermatology Life Quality Index (DLQI) questionnaire and whether the information influenced treatment decision-taking. Methods: The DLQI was completed by adult patients attending a dermatology secondary-care clinic as they arrived at their appointment and given to the clinician. Clinicians recorded whether the DLQI information was used and whether it influenced treatment decision-making. Results: A total of 417 patients attended and 268 questionnaires (64.3%) were completed. The mean DLQI score was 7 (median = 5, range = 0–30). In 64 consultations (28.8%), clinicians used the DLQI information; in 37 of these consultations (57.8%) the DLQI information influenced the clinicians’ treatment decision-making. The mean DLQI score for these 37 consultations was 11.3 (median = 10.0, range = 0–29), indicating a large effect on patients’ QoL. QoL discussion occurred in 85 of 98 consultations observed. The domains of QoL most frequently discussed concerned symptoms (74 consultations) and problems caused by the treatment (24 consultations). Conclusions: Clinicians may use formal QoL information if available in routine clinics. Treatment decisions may be influenced for those with high QoL impairment. Routine systematic assessment of QoL may therefore be of benefit.

Dermatology Life Quality Index: influence of an illustrated version

Abstract: The illustrated version was superior to the text-only version in terms of patient preference and ease of use, but it was not possible to demonstrate exact equivalence between the two versions.
