BACKGROUND Patient-reported quality of life is strongly affected by some dermatologic conditions. We developed a Japanese version of the Dermatology Life Quality Index (DLQI-J) and used psychometric methods to examine its validity and reliability. METHODS The Japanese version of the DLQI was created from the original (English) version, using a standard method. The DLQI-J was then completed by...

Study population The study population comprised a hypothetical cohort of patients with moderate-to-severe psoriasis. Three sub-groups of patients were considered on the basis of disease severity, as represented by two scores, the Psoriasis Area and Severity Index (PASI) and the Dermatology Life Quality Index (DLQI). The three sub-groups were PASI and DLQI greater than 10, PASI and DLQI greater ...

INTRODUCTION The effect of dermatological disease on patients' quality of life is a minimally addressed issue in Sri Lanka. One reason is the unavailability of a standardised measuring tool. This study was done to produce and validate a Sinhala version of the Dermatology Life Quality Index (DLQI), which is an internationally accepted quality of life measuring instrument. METHODS The English v...

Monitoring of biological treatment efficacy for psoriasis is based on clinical evaluation and patient's quality of life. However, long-term correlation between Psoriasis Area and Severity Index (PASI) and Dermatology Life Quality Index (DLQI) in real life has not been studied in patients treated with ustekinumab. All patients with psoriasis treated with ustekinumab at our department were includ...

OBJECTIVE The aim of this study was to assess the quality of life (QOL) of patients with psoriasis in Japan using Dermatology Life Quality Index (DLQI). Furthermore, we had evaluated the correlation between DLQI and clinical severity of psoriasis. METHODS The Japanese version of DLQI was used to assess the QOL of patients. Psoriasis area and severity index (PASI) and Itch visual analogue scal...

INTRODUCTION The Psoriasis Area Severity Index (PASI) is the most widely used scale for assessing the severity of psoriasis and for therapeutic decision making. On the basis of the PASI score, patients have been stratified into 2 groups: mild disease and moderate-to-severe disease. OBJECTIVE To draft a proposal for the definition and characterization of moderate psoriasis based on PASI and De...

BACKGROUND Chronic spontaneous/idiopathic urticaria (CSU/CIU) has substantial detrimental effects on health-related quality of life (HRQoL) with an effect comparable to or worse than many other skin diseases. OBJECTIVE To assess the effect of omalizumab on CSU patients' HRQoL, measured by the Dermatology Life Quality Index (DLQI) in three phase III studies ASTERIA I, ASTERIA II and GLACIAL. ...

BACKGROUND The Dermatology Life Quality Index (DLQI) is the most widely used measure of health-related quality of life (HRQoL) associated with skin disease. Recently, the psychometric properties of the DLQI have caused some controversy because the instrument appears not to meet the requirements of modern test theory. The purpose of this study was to assess whether these psychometric issues also...

INTRODUCTION In medical terms, alopecia is considered a relatively mild dermatological condition that nevertheless is a serious condition, but it causes major depression in many sufferers. Alopecia areata (AA) and androgenetic alopecia (AGA) are the main types of hair loss. This study assessed the quality of life (QoL) of Chinese patients with AA and AGA using the Dermatology Life Quality Index...

Subjective-symptom tools used in dermatology have rarely been experimentally tested for cognitive "focus" and "framing" biases. We investigated the effects of affective biases on the Dermatology Life Quality Index (DLQI), the Global Health Question and visual analogue scores. Two experiments tested the response to affect-eliciting words and film. We demonstrated no significant difference in med...
