International study on prevalence of itch: examining the role of itch as a major global public health problem.

BACKGROUND: Very few studies evaluated the global prevalence of pruritus. OBJECTIVE: To assess its prevalence according to age, gender, ethnicity, and geographic regions. METHODS: An international cross-sectional study was conducted in 20 countries from January to April 2023. Participants were asked to complete a questionnaire on sociodemographics, confirm the presence or absence of a skin disease in the last 12 months and the presence or absence of pruritus in the last 7 days. RESULTS: The studied sample included 50552 individuals. The worldwide prevalence of pruritus was 39.8%. The age group ≥65 had the highest prevalence (43.3%). The prevalence was 40.7% among women and 38.9% among men (p<0.001). There was no significant difference between ethnicities (p=0.14). Compared to North America (41.6%), the prevalence of pruritus was significantly lower in Europe (35.9%, p<0.001), Australia (38.4%, p=0.017), East Asia (40.2%, p=0.04), and Latin America (36.5%, p<0.001), and higher in Africa (45,7%, p=0.007). No significant difference was found with the Middle East (40.2%, p=0.36). The prevalence was 40.3% in developed countries and 38.7% in BRICS countries 40.7% (p<10-3). LIMITATIONS: No information about the severity or type (acute, chronic) of pruritus. CONCLUSION: Global prevalence of pruritus revealed age, gender, and geographic region differences, with no ethnic differences.

Impact of Atopic Dermatitis on Adult Women's Lives: A Survey of 1,009 French Women.

Atopic dermatitis (AD) is one of the most common inflammatory diseases, and has a higher prevalence among females in adulthood. The aim of this observational, cross-sectional, survey-based study was to evaluate the impact of AD on the daily lives of adult women patients. A scientific committee composed exclusively of women constructed a specific questionnaire in partnership with the French Eczema Association. Severity of AD was evaluated with the Patient-Oriented Eczema Measure (POEM). A sample of 1,009 adult women (mean age ± standard deviation: 41.8 ± 14.2 years) with AD was identified from a representative sample of the French population (82% response rate 1,230 women surveyed). According to the POEM, 50.64% (n = 511) of subjects were identified as having mild AD, 39.35% (n = 397) moderate AD, and 10.01% (n = 101) severe AD. Overall, 67.7% (n = 682) reported that their eczema involved a visible area (face, neck or hands), and 19.6% (n = 198) a sensual area (breasts/chest, genital area or buttocks). Of the 720 women with menstrual cycles, exacerbations of AD were reported to occur mostly before (50.6%) and during (48.3%) menstruation. A small proportion of women, 7.3% (n = 74), reported being afraid of  becoming pregnant because of their eczema. If AD involvement was in a visible area it had a greater impact on romantic relationships, sexual relationships and occupation. If AD involvement was in a sensual area it had a greater influence on romantic relationships and sexuality. Particular attention should be given to patients with localization of AD on the face, neck or hands, as they have a higher risk of social exclusion. Moreover, these results should encourage health professionals to ask patients with AD about the possible involvement of sensual areas.

Sun exposure and protection habits: Self-reported attitudes, knowledge and behaviours.

BACKGROUND: As exposure to UV radiation is the primary modifiable environmental risk factor associated with skin cancer, it remains the principal focus of most prevention strategies. Numerous sun protection campaigns have been implemented worldwide; however, their impact on the actual incidence and mortality rates of skin cancer seems to be limited. To create successful skin cancer prevention campaigns, it is important to have a comprehensive understanding of individuals' attitudes and behaviours regarding sun protection. The aim of the current study was to determine and report on the prevalence of self-reported attitudes, knowledge and behaviours regarding two of the major sun protection recommendations-avoidance of sun exposure and use of sunscreens-in an international representative sample across five continents. METHODS: This cross-sectional study was conducted in 20 countries using a web-based online survey. FINDINGS: A total of 50,552 individuals, comprising 25,388 men (50.22%) and 25,164 women (49.78%), participated in the survey. Among them, 83.2% reported having been voluntarily exposed to the sun (for sun-basking reasons) at least once in the last 12 months, and 47.96% acknowledged being exposed to the sun between the hours of 10 AM and 4 PM. The primary reason for non-adherence was that these hours were the most convenient times (32.28%). Only 24.05% reported applying sunscreen every 2 h when outdoors. Forgetfulness was the primary reason as provided by 27.79% of participants. Males and older age groups were less likely to adopt sun-protective behaviours around the world. Forgetfulness and the challenges posed by time constraints seem to be the biggest barriers to proper adherence. INTERPRETATION: These findings should prompt the collaboration with health authorities and the manufacturers to enhance adherence by setting reasonable sunscreen prices and creating formulations that make their application less burdensome.

The Ectodermal Dysplasias-Burden of Disease Score: Development and Validation of an Ectodermal Dysplasia Family/Parental Burden Score.

Ectodermal dysplasias are genetic conditions affecting the development and/or homeostasis of 2 or more ectodermal derivatives, including hair, teeth, nails, and certain glands. No tool is available to assess the burden of ectodermal dysplasias and its multidimensional impact on patients and their families. This study developed and validated a familial/parental 19-item burden questionnaire designed specifically for ectodermal dysplasias. Each group of questions was linked to 1 of the following dimensions: (i) Impact of the disease on social life and hobbies; (ii) Future prospects; (iii) Restraint of the disease on outdoor activities; (iv) Financial burden of the disease; (v) Acceptance of the disease. Cronbach's alpha was 0.91 for the entire Ectodermal Dysplasias-Burden of Disease (ED-BD) scale, confirming excellent internal coherence. Intradimensional coherences all demonstrated excellent reliability (α > 0.76). The ED-BD questionnaire was highly correlated with the Short Form-12 and Psychological General Well Being Index validated questionnaires. Cultural and linguistic validation in US English was conducted. Development and validation of the questionnaire was based on data from patients with the 2 main ectodermal dysplasias subtypes. This ED-BD questionnaire represents the first specific assessment tool for evaluating the familial/parental burden of ectodermal dysplasias.

Impact of Atopic Dermatitis on Patients and their Partners.

Atopic dermatitis is a chronic, relapsing and inflammatory skin disease. The impact of atopic dermatitis on the partners living with patients has been poorly investigated. The objective of this study was to evaluate the impact of atopic dermatitis in the daily lives of adult patients and to assess the burden of the disease on their partners. A population-based study was conducted on a representative sample of the general population of French adults aged 18 years of age using stratified, proportional sampling with a replacement design. Data were collected on 1,266 atopic dermatitis patient-partner dyads (mean age of patients 41.6 years, 723 (57.1%) women). The mean age of partners was 41.8 years. Patient burden, measured by the Atopic Dermatitis Burden Scale for Adults (ABS-A) score, was closely related to the objective atopic dermatitis severity: the mean score in the mild group (29.5) was significantly lower than in the moderate (43.9) and severe groups (48.6) (p < 0.0001). Partner burden, measured by the EczemaPartner score, was highly related to atopic dermatitis severity (p < 0.0001). Daytime sleepiness, measured by the Epworth Sleepiness Scale, showed a mean score of 9.24 in patients and 9.01 in their partners, indicating impaired sleep. Atopic dermatitis was found to decrease sexual desire in 39% and 26% of partners and patients respectively.

Use of multiple correspondence analysis to explore associations between caregivers and sun protective habits during summer vacations.

BACKGROUND: Childhood exposure to ultraviolet radiation (UVR) plays an important role in the development of keratinocyte carcinomas and melanomas. Therefore, sun protective measures ought to be implemented during early childhood. Young children are largely dependent upon adult care providers in order to achieve proper sun protection. OBJECTIVES: To develop effective photoprotection in children, it is necessary to understand caregivers' attitudes and knowledge about UVR exposure. This study aimed to explore the variables associated with sun protective behaviour in parents and grandparents during summer vacations. METHODS: A multinational, cross-sectional study was conducted using a web-based online survey with a representative sample of parents and grandparents of children aged ≤ 12 years, who cared for their children/grandchildren for at least 2 weeks during the summer of 2021, in five countries (France, Germany, Spain, Italy and the USA). Multiple correspondence analysis (MCA) was used to explore in an unbiased way the possible relationships among all the variables and to identify specific profiles. RESULTS: A total of 6190 adult participants responded to the questionnaire: 5104 parents (average age 42.0 years, 54.3% women) and 1086 grandparents (average age 64.2 years, 55.5% women). MCA allowed discrimination of two groups of respondents based on their answers: a profile with 'unprotected sun exposure habits' vs. those with 'protective sun exposure habits'. Parents fell in closer proximity to the 'unprotected sun exposure habits', and 'sunburn reported in youngest child'. Grandparents adopted more cautious behaviours than parents. Nevertheless, grandparents fell in proximity to 'having exposed the grandchild to the sun between 11 h and 17.00 h', 'not using an umbrella' and 'not using sunglasses'. CONCLUSIONS: Although grandparents appear to adopt more cautious behaviours than parents, many gaps in proper sun protection behaviour were observed in both groups of caregivers.

The impact of visible scars on well-being and quality of life: An international epidemiological survey in adults.

INTRODUCTION: Scars are visible marks from various causes, including surgery, skin injury, burning or dermatological disease, and may impact the quality of life. OBJECTIVE: To assess the impact of scars on quality of life (QoL). MATERIAL AND METHODS: Data about sociodemography, presence, origin, and symptoms of scars were collected using an Internet survey between April and May 2020. Overall, 11,100 individuals answered the survey. In total, 48.5% of the responders had at least one scar of less than 1 year of age. Scars were mainly reported on the abdomen and face. Globally, 28.9% of subjects with recent scars reported pain, 23.7% reported burning, 35.0% reported itching, and 44.1% reported redness. Subjects were most frequently bothered by the visibility of their scars and the presence of marks. Incidences were significantly higher than for those with older scars. The average DLQI score was 7.44; it decreased to 2.90 after 1 year. Subjects with scars aged less than 3 months had their QoL more frequently impacted (33.9%) than those with scars aged 12 months or more (10.2%). In subjects reporting skin discomfort, clinical symptoms significantly impacted body movement, choice of clothes, leisure activities, and sexual life more than in those reporting no skin discomfort. Moreover, subjects felt significantly more impacted in their daily lives due to their skin discomfort. When feeling bothered by the visibility of their scars, significantly more subjects were also impacted in their body movement, choice of clothes, leisure activities, and sexual life than those subjects who did not feel bothered. Moreover, significantly more subjects felt embarrassed. CONCLUSION: Scars significantly impact the subjects' quality of life. This impact is even more important when caused by recent and visible scars, with a lower DLQI score in subjects with more aged than in those with recent scars.

Burden of caregivers and out-of-pocket expenditures related to epidermolysis bullosa in France.

INTRODUCTION AND OBJECTIVES: Inherited epidermolysis bullosa (EB) is a heterogeneous group of genodermatoses characterized by localized or generalized skin and/or mucosal fragility. The objective of this work was to evaluate in France the burden of disease and out-of-pocket (OOP) expenditures for families with a child affected by EB. MATERIAL AND METHODS: A digital questionnaire was built and distributed to parents of children with EB in partnership with the patients' association DEBRA France. The questionnaire collected clinical and socioeconomic characteristics including the estimated amount of money caregivers had to pay out of their own pockets. The burden of caregivers was assessed using the validated Epidermolysis Bullosa Burden of Disease (EB-BoD) tool. Linear univariate regression models were conducted to search for factors associated with higher burden and higher OOP. RESULTS: Between October and December 2021, 77 parents answered the questionnaire. The responder was the child's mother in 77% (n = 59) of cases. Parents represented 40 girls and 37 boys with a mean age of 7.5 years and with different EB types and disease severity. The mean BE-BOD score was 63.9 ± 20.2. The mean score observed in children with severe EB was 69.0 ± 21 versus 59.0 ± 18.6 for moderate/mild. Similarly, the mean BE-BOD scores observed in parents performing daily wound care were 67.9 ± 19.6. All parents (100%) reported OOP expenses. The mean annual OOP cost was 4129€ ± 4321€. Linear regression demonstrated that for each one-point increase in the EB-BoD score, OOP expense increases by 91.1 euros (35.1-147) p = 0.002. CONCLUSION: EB places a considerable burden on families' daily lives. This burden is closely associated with OOP expenditures to manage EB which were on average 20 times higher compared with the French population.

Patient Unique Stigmatization Holistic tool in dermatology (PUSH-D): Development and validation of a dermatology-specific stigmatization assessment tool.

BACKGROUND: The skin plays an important role in establishing interpersonal relationships, and thus visible skin disorders, which have a significant impact on physical appearance, influence other people's behaviours and attitudes. OBJECTIVE: To develop and validate a dermatologic-specific questionnaire to evaluate stigmatization in individuals with visible skin conditions. METHODS: Items were generated by a verbatim report based on qualitative interviews with patients with various dermatologic conditions. Subsequently, a study was implemented for psychometric analysis. A dermatology-specific stigmatization questionnaire (PUSH-D) was refined via item reduction according to inter-question correlations, consensus among experts and exploratory factor analysis. Internal consistency was determined by calculating Cronbach's α. Concurrent validity was determined by calculating the correlation between PUSH-D and the Dermatology Life Quality Index (DLQI) and the Rosenberg Self-Esteem Scale (RSES). RESULTS: From a primary list of 22 items, PUSH-D was reduced to a 17-item questionnaire, covering two pertinent dimensions based on the exploratory factor analysis. Construct validity was demonstrated, and PUSH-D showed good internal consistency (Cronbach's α = 0.9). PUSH-D correlated strongly with the DLQI 0.72 (p < 0.001) and moderately with the RSES 0.49 (p < 0.001). CONCLUSION: PUSH-D allows a comprehensive view of the degree of stigmatization in visible skin disorders, as well as the comparability of stigmatization levels across various skin conditions.

Quality of life and stigmatization in people with skin diseases in Europe: A large survey from the 'burden of skin diseases' EADV project.

BACKGROUND: Several large studies on the burden of skin diseases have been performed in patients recruited in hospitals or clinical centres, thus missing people with skin diseases who do not undergo a clinical consultation. OBJECTIVES: To evaluate the burden of the most common dermatological diseases in adult patients across Europe, in terms of quality of life, work life, and stigmatization. METHODS: Population-based survey on a representative sample of the European general population aged 18 years or older. Participants who declared to have had one or more skin problem or disease during the previous 12 months completed the Dermatology Life Quality Index questionnaire, and answered questions regarding the impact of their skin disease on daily and work life, anxiety/depression, and stigmatization. RESULTS: The study population included 19,915 individuals, 44.7% of whom were men. Quality of life was particularly impaired in people with hidradenitis suppurativa (HS), and sexually transmitted diseases. About a half of participants with acne, alopecia, or chronic urticaria, and about 40% of those with atopic dermatitis (AD), skin cancers, or psoriasis reported a modest to extremely large effect of the disease on their quality of life. Overall, 88.1% of participants considered their skin disease as embarrassing in personal life and 83% in work life. About half of the respondents reported sleeping difficulty, feeling tired, and impact of the disease on taking care of themselves. Concerning stigmatization, 14.5% felt to have been rejected by others because of the skin disease, and 19.2% to have been looked at with disgust. Anxiety and depression were frequently reported by patients with all the diseases. CONCLUSIONS: Skin diseases may heavily affect patients' daily and work life, and cause feelings of stigmatization. An early intervention is needed to avoid consequences on the patients' life course.

Public perception of dermatologists in Europe: Results from a population-based survey.

BACKGROUND: The public perception of dermatology has been poorly investigated in Europe. OBJECTIVE: To determine the general public's perception of dermatologists in Europe. METHODS: This multinational, cross-sectional study was conducted within the framework of the EADV population-based survey on the 'Burden of skin diseases in Europe'. Data were collected using a web-based online survey on a representative sample of the general populations aged 18 years or more of 27 European countries. Proportional quota sampling with replacement design was used for each country. RESULTS: A total of 44,689 adult participants responded to the questionnaire, of whom 18,004 visited a dermatologist in the preceding 3 years. The dermatologist was the second most often visited specialist among all medical specialties, with 69.7%, 72.1%, 42.1% and 78.1% of participants in Western Europe (WE), Eastern Europe (EE), Northern Europe (NE) and Southern Europe (SE), respectively, having consulted a dermatologist over the past 24 months. Most participants across all regions agreed that the dermatologist was the first healthcare provider for chronic skin diseases (61.9% in WE, 69.8% in EE, 45.7% in NE and 60.4% in SE) and for skin cancers (65.5% in WE, 67.6% in EE, 42.4% in NE and 63.0% in SE). The five most common reasons for visiting a dermatologist among all participants were: naevi check-up or skin cancer screening (20.2%), chronic skin diseases (16.5%), acute skin diseases (12.4%), cosmetic advice or procedure (10.2%), hyperpigmentation or congenital lesions (9.1%) and hair or nail disorder (7.7%). Most participants (84.6% in WE, 82.5% in EE, 78.3% in NE and 82.8% in SE) were very swatisfied/somewhat satisfied with the service provided. CONCLUSION: Our study findings underscore the central role of dermatologists in skin health and highlights them as valued and trusted care providers across Europe. Understanding the perceived position of the dermatologist is the first step in improving health policy development and implementation. Notably, access to a dermatologist was lowest in NE, probably reflecting differences in healthcare organizational structures or possibly cultural differences in healthcare seeking behaviour.

The journey of patients with skin diseases from the first consultation to the diagnosis in a representative sample of the European general population from the EADV burden of skin diseases study.

BACKGROUND: The journey of patients with skin diseases through healthcare has been scarcely investigated. OBJECTIVE: To analyse the journey of people with skin diseases in the different healthcare environment in Europe. METHODS: This multinational, cross-sectional, European study was conducted on a representative sample of the adult general population of 27 European countries. The prevalence of the most frequent skin diseases was determined. Information was collected on the patient journey from the first medical consultation to the diagnosis, and the reasons for not consulting a healthcare professional. RESULTS: On a total of 44,689 individuals, 30.3% reported to have consulted a dermatologist during the previous 2 years. Participants consulted mainly for mole control or skin cancer screening (22.3%), followed by chronic skin diseases (16.2%). The diagnoses of acne, atopic dermatitis, psoriasis and rosacea were made most frequently by a dermatologist, while fungal skin infections were diagnosed more often by a general practitioner (GP), and sexually transmitted diseases (STD) by other specialists. The diagnosis was not always definitive at the first consultation, in particular for STD. The percentage of people who did not consult a healthcare professional for their skin disease was particularly high for acne (36.4%), alopecia (44.7%) and fungal infection (30.0%). Moreover, 17.7% of respondents with psoriasis did not consult. A high percentage of participants with alopecia thought that the disease was not worrying, while patients with psoriasis often answered that they were able to manage the disease since they had already consulted a doctor. Many patients with acne (41.1%) and fungal infection (48.2%) thought that they were able to handle the disease by themselves. CONCLUSION: The analysis of the self-reported medical journey of patients with common skin diseases may allow to understand the unmet needs of patients, thus improving outcomes and reducing expenses.

Pruritus, Pain, and Depression Associated with the Most Common Skin Diseases: Data from the French Study "Objectifs Peau".

BACKGROUND: The prevalence and impact of pruritus, pain, and other sensory symptoms in skin diseases are poorly known. OBJECTIVE: To assess the frequency of these symptoms with dermatoses and their association with depression using data from the "Objectifs Peau" survey. METHODS: A representative sample of 20,012 French individuals was created using the usual quota method. RESULTS: When patients suffered from both pruritus and skin pain, they had a higher relative risk of psychological suffering (2.9) than those who suffered only from pruritus (1.4) or skin pain (1.2). Pruritus was reported in 48.55% of patients with acne, 43.24% with mycoses, 44.35% with warts, and 36.51% with rosacea. For skin pain, the results were 11.22%, 27.59%, and 16.13% for atopic dermatitis, acne, and warts, respectively. Other unpleasant sensations, such as tingling or burning, were also frequently reported. CONCLUSION: Pruritus, pain, or other sensory symptoms were found to be common not only in classic pruritic skin diseases but also in acne, rosacea, or warts. The association of pruritus and pain dramatically increased psychological suffering. These symptoms must be systematically searched for in patients, especially since new therapeutic possibilities are emerging for the symptomatic treatment of pruritus.

Sleep Disorders and Psoriasis: An Update.

Psoriasis alters patients' quality of life. Among the disorders associated with psoriasis, sleep disorders are common, although they are not directly assessed by most quality-of-life scores. Thus, the specific evaluation of sleep disorders using dedicated scores is necessary, especially because such disorders alter patients;' physical and psychological health. The relationship between psoriasis and sleep disorders has been shown in numerous studies, but has not yet been fully elucidated. The aim of this study was to update knowledge of sleep disorders in patients with psoriasis, through a review of the scientific literature since 1980. This work covers several topics of interest, such as sleep assessment methods, the prevalence of sleep disorders in patients with psoriasis, factors predictive of sleep disorders in patients with psoriasis, the impact of sleep disorders on comorbidities and quality of life, pathogenic mechanisms, obstructive sleep apnoea and restless leg syndromes, and the impact of biotherapy treatments on sleep disorders in patients with psoriasis.

Patient Perception of the Diagnosis Announcement and its Impact on Quality of Life of Patients with Primary Melanoma or Basal Cell Carcinoma.

An improved understanding of the impact of skin cancer on patients' daily life may optimize disease management. This questionnaire survey of adult patients in real-world settings aimed to assess patient perception of the diagnosis announcement, and the impact of the diagnosis on the patients' professional and personal life. Data from 355 patients with melanoma and 320 patients with basal cell carcinoma (BCC) were analysed. Melanoma significantly impacted the couple, and sexual relationships, as well as family and social life, and reduced the patient's libido more significantly than did BCC (all p < 0.05). Melanoma and BCC significantly impacted the patients' professional and personal lives. The word "cancer" used for a BCC announcement has a high anxiety-producing meaning for the patient. The announcement of each skin cancer should be made during a dedicated consultation, with more time devoted to the patient and with specific empathy, in order to improve reassurance of the patient.

Cross-cultural assessment of the impact of eczema in six countries with different lifestyles.

Atopic dermatitis or eczema is a common skin disease in children but also in adults; in Europe alone, it affects more than 23 million adults. At the time of internationalization of studies, it seems important to know that the impact of eczema is different according to lifestyle. It seems that the use of two patient-reported outcomes, one specific, the other not, to measure the impact of eczema is relevant and should be recommended.

Evaluation of factors associated with sexual dysfunction in psoriasis in a cohort of 1409 patients.

We report on the sexual disorders common in patients with psoriasis, and examine the underlying reasons, including the use of psoriasis treatments that can result in sexual difficulties.

Prevalence of radiotherapy, chemotherapy and access to supportive care in cancer in Brazil, China, France, Russia and the USA.

OBJECTIVES: The objective of this study is to assess the prevalence of treatment with radiotherapy and/or chemotherapy in the general adult population of five countries (Brazil, China, France, Russia and the USA) and to evaluate the use of different Supportive Care in Cancer (SCC) services. METHODS: A total of 11,100 individuals representing the general population over 18 years of age were recruited from the five countries via a rigorous quota sampling method. RESULTS: There are between 4.1% and 8.78% of respondents reported having undergone medical cancer treatment. Among these subpopulations, the use of at least one SCC was reported by 63% to 86% of respondents. The most commonly used SCC was psychological counselling in France, dietary counselling in Brazil and China, participating in a focus group in the USA and using alternative medicine in Russia. Alternative medicines were chosen by 50% to 61% of patients in every country. CONCLUSION: This study provides information on the prevalence of patients treated by chemotherapy and/or radiotherapy in representative populations from five countries. Among them, SCC was widely used. However, these uses varied both in proportion and choice, given the cultural differences in patients' and families' health beliefs and values, differences among organisations, in available resources and in ethics and policies among countries.

Association of Sensitive Eyes with Sensitive Skin: A Worldwide Study of 10,743 Subjects.

INTRODUCTION: Sensitive eyes are commonly reported by patients, but there are very few epidemiological studies on this disorder. The aim of this study was the evaluation of the self-reported frequency of sensitive eyes and the association with sensitive skin. METHODS: A survey was performed on a representative sample of the population aged more than 18 years in five different countries (Brazil, China, France, Russia, and the USA). All participants answered a questionnaire on sociodemographic characteristics; skin phototype; eye color; tobacco consumption; exposure to sunlight, air pollution, or having pets; and sleep disorders. The presence of sensitive eyes, eyelids, or skin and their triggering factors were assessed with specific questions. RESULTS: A total of 10,743 individuals (5,285 men and 5,458 women) were included in the study. Among them, 48.2% reported having sensitive skin and 46.0% reported having sensitive eyes. Sensitive eyes were more frequently reported by women (46.5%) than men (39.4%) in all countries, with the exception of China. The presence of sensitive eyes was more frequent if skin was very sensitive. More than half of subjects with sensitive eyes declared that their triggering factors were exposure to sunlight, dust, touch pad screens, or computer screens or dry air. They were more exposed to pollution and tobacco. Their phototype (including eye color) was lighter. DISCUSSION/CONCLUSION: This large study shows that self-declared sensitive eyes are very frequent and commonly associated with sensitive skin. Triggering factors of sensitive eyes are more specific.

Creation of a tool to evaluate supportive care.

RATIONAL: The absence of a specific tool to evaluate the impact of supportive care in general and socioesthetics (SE) in particular is undoubtedly at the origin of the lack of published research based on scientific standards. OBJECTIVE: We developed a supportive-care, patient-reported outcome questionnaire using the multistep methods, following COSMIN recommendations. METHODS: The Patient Centricity Questionnaire (PCQ) was developed using the standardized methodology for designing patient-reported outcome (PRO) questionnaires according to the following steps: elaboration of the questionnaire, measurement properties of the questionnaire, internal and external validation, test-retest validation and translation, cross-cultural adaptation, and cognitive debriefing. A multidisciplinary work group was designed including professionals, such as physicians, public health experts, sociologists, supportive-care experts, and socioestheticians. RESULTS: Our questionnaire includes 11 items. It is scored by adding each Visual Analogue Scale [VAS], making it range from 0 to 110, with a higher benefit when the score is higher. The Cronbach's α coefficient is 0.88 for the entire questionnaire. As the questionnaire is a reflection of the patient's feelings, it is quite natural that the name "Patient Centricity Questionnaire" (PCQ) was retained and validated by the Scientific Committee. The PCQ correlated negatively and moderately with the Perceived Stress Scale [PSS], positively and moderately with the mental dimension of the Short Form-12, and poorly with the Well Beng 12 [WB12], the physical dimension of the SF-12, and the satisfaction VAS. CONCLUSION: Constructed according to the recommendations, the PCQ meets the prerequisite for this type of questionnaire. Its short format and simplicity of use allow it to be used by a large number of people. The PCQ is a simple, reliable, easy-to-use, and validated tool for research teams, making it possible for randomized studies to prove the impact of supportive care in general and SE in particular, on the patient's quality of life.
