The perception of life quality impairment in melasma is influenced by low scholarly, low family income, single marital status and greater clinical severity.

BACKGROUNDMelasma has a major impact on quality of life. MELASQoL is the only validated specific psychometric instrument to evaluate melasma QoL.OBJECTIVETo develop and validate a multidimensional questionnaire for evaluating quality of life related to facial melasma.METHODSCross-sectional study performed in 2 institutions (public and private) from Brazil. Two focus groups were carried out: 5 board-certified dermatologists and 10 melasma patients, indicating the dimensions and significant units of melasma QoL. The preliminary questionnaire with 49 itens was applied to 154 facial melasma patients. Item reduction was performed by Rasch analysis. Parallel evaluations of clinical (MASI), demographic, and QoL aspects (MELASQoL, DLQI) were performed. The dimensional structure was assessed by confirmatory factor analysis. Temporal stability was tested in a subgroup of 42 individuals within 7-14 days.RESULTSThe mean (SD) age of the 154 interviewed subjects was 39±8 years, and 87% were females. The median (p25-p75) DLQI and MELASQoL were: 2 (1-6) and 30 (17-44). HRQ-Melasma consisted of 19 items distributed in 4 dimensions: Physical/Appearance, Social/Professional, Psychological, and Treatment. Cronbach’s alpha for HRQ-Melasma was 0.96, and >0.74 for each dimension. There was high correlation between HRQ-Melasma and DLQI and MELASQoL (rho=0.80 and 0.83), but modest with MASI (rho=0.35). Dimensional structure of HRQ-Melasma was stated by confirmatory factor analysis coefficients. Test-retest analysis disclosed an intraclass correlation coefficient of 0.91 (p<0.01).STUDY LIMITATIONSSingle-center study.CONCLUSIONSA specific instrument to evaluate QoL in melasma with multidimensional characteristics was developed and validated, with appropriate psychometric performance.

Objective To identify the prevalence and factors associated with depression and anxiety in patients with psoriasis. Background Psoriasis is a chronic, non‐contagious, autoimmune inflammatory skin disease associated with psychological comorbidities. Design A cross‐sectional study conducted between March 2017–December 2018 in a dermatology infirmary and outpatient clinic of a public hospital in the inner State of São Paulo (Brazil). Methods We used questionnaires with sociodemographic data and clinical history, the HADS (Hospital Anxiety and Depression Scale), DLQI‐BRA (Dermatology Life Quality Index) and PASI (Psoriasis Area Severity Index). The correlations between variables were explored using multivariate techniques. STROBE checklist was applied as the reporting guideline for this study (File S1). Results A total of 281 participants were included, of which the majority were female 146 (52%), with a mean age of 52.1 years (SD: 13.8), elementary school 154 (55%), married/cohabiting 209 (74%) and with low income 201 (72%). The median (p25–p75) time with the disease was 14 years (7–23). Regarding the quality of life, 31% of respondents reported being little affected by the disease. The prevalence of depression was 19% and that of anxiety was 36%. The multivariate analysis showed that the variables that influenced the anxiety and depression scores were as follows: DLQI‐BRA, income, female sex, illness length and age. For the multiple correspondence analysis, the highest levels of anxiety and depression referred to women, middle age, lower income and low PASI. Conclusion The prevalence of anxiety and depression symptoms was low. Female sex, income, age, illness length and quality of life were associated with anxiety and depression scores in patients with psoriasis. Relevance to clinical practice Due to the scarcity of studies in the field of nursing with psoriasis patients, we believe these findings contribute to the reorganisation of the care provided, allowing nurses to timely identify mood disorders such as anxiety and depression and adopt the necessary measures to a service and/or specialised referral.

Background: Psoriasis is a multifactorial inflammatory disease prevalent in dermatology. We aimed to understand the perceptions of patients living with psoriasis in relation to their quality of life and to identify aspects to improve it. Methods: This is qualitative research carried out in a dermatology outpatient clinic of the São Paulo State University (UNESP) medical school, Botucatu, Brazil, with 81 psoriasis patients. The interviews were transcribed and analysed using the Discourse of the Collective Subject method (DCS). Results: Quality of life was linked to well-being, happiness, leisure, good food and financial stability. However, disease symptoms, social and clothing restrictions, impairment of professional activities and the absence of a cure, negatively influenced their perceptions. Suggestions for improvements included an increase of public awareness, stress reduction, disease acceptance and multidisciplinary care. Conclusion: The meanings of quality of life revealed by the participants are subjective, multidimensional, linked to moments experienced by them and to the health-disease process. Public health policies promoting reduction in social stigma and stress as well as multidisciplinary approaches towards care can contribute to improvements of QoL in psoriasis.

In view of the lack of studies involving family members' comfort and needs, we believe that these results can guide nursing proposals focused on the family members, in line with the associations found among different variables that influenced the results.

The aim of this study was to analyze scientific production concerning the validation and cultural adaptation of quality of life evaluation instruments for patients with melasma and to offer a critical reflection on these methods. A literature review was performed based on a search of the Web of Science, Bireme, PubMed, Elsevier Scopus, and Google Scholar databases. All published articles from indexed periodicals in these electronic databases up to December 2015 were included. Eight articles were identified, of which only one (12.5%) referred to the development and validation of a specific instrument for evaluation of the quality of life of melasma patients. An additional six articles (75%) referred to transcultural adjustment and validation of the same instrument in other languages, and another (12.5%) article reported the development of a generic instrument for evaluation of quality of life in patients with pigment disorders. This review revealed only one specific instrument developed and validated in different cultures. Despite being widely used, this instrument did not follow the classic construction steps for psychometric instruments, which paves the way for future studies to develop novel instruments.
