“…8 Five studies [9][10][11][12][13] analysed the dimensionality of the CADI through factor analysis. Four of these reported the CADI to have two factors [9][10][11]13 (two of which identified the same two factors) 9,13 and one study reported the CADI to have one factor (Table S1; see Supporting Information). 12 The two studies 9,13 reported that the first dimension comprised three items addressing emotional wellbeing and the second dimension comprised the two items addressing the social impact of acne.…”

The Cardiff Acne Disability Index (CADI) is a questionnaire designed to measure the quality of life of teenagers and young adults with acne. It has been used clinically and within therapeutic research globally. This review aims to appraise all published data regarding the clinical and research experience of the CADI, its psychometric properties and validation, from its publication in 1992 until September 2020, in a single reference source. A literature search was conducted using MEDLINE via Ovid, PubMed, EBSCOhost, Web of Science and Scopus. All full articles in the English language were included. A total of 96 clinical studies were identified and analysed. The CADI has been used in 44 different countries, including four multinational studies, and has validated translations in 25 languages. Overall, 29 therapeutic interventions have used the CADI, demonstrating its responsiveness to change. The reliability of the CADI has been assessed in 14 studies through test-retest and internal consistency studies. In total, 57 studies have demonstrated aspects of its validity through correlation to other measures, and five studies have investigated the dimensionality of the CADI. There is evidence of high internal consistency, test-retest reliability, responsiveness to change and significant correlation with other objective measures. The minimal clinically important difference and validated score meaning bands have not yet been reported. This information is needed to improve the interpretability of CADI scores for clinical use and in research. The authors of the CADI have also rephrased Question 2 of the measure to ensure inclusivity.What is already known about this topic?• Acne significantly impacts quality of life in patients.• There are several skin-specific and acne-specific instruments used in day-to-day practice and research.• The validation and other measurement properties of the Cardiff Acne Disability Index (CADI) have not been easily accessible.What does this study add?• The CADI has been extensively used and is a reliable and valid tool.• There is a need to develop validated CADI score bands and calculate the minimal clinically important difference.• The CADI authors have rephrased Question 2 to ensure that the wording is inclusive.• There is inconsistent reporting of CADI data and a need for guidelines when reporting and publishing quality-of-life data.

“…Age, gender, occupation, concominant diseases of the patients and their duration, localization and symptoms of acne vulgaris were recorded. Clinical assessment of acne was evaluated by the Global Acne Grading System (GAGS) [7]. In this scoring system, a coefficient (the forehead, the right cheek and the left cheek as 2, the nose and the chin as 1, the chest and the upper back as 3) for each area is taken into consideration by dividing the face, the chest and upper back into six parts, considering the width of the region and the density and distribution of the pilosebaceous units in that area.…”

“…After evaluating each area separately, multiplying the score obtained by the most severe lesion type in that area and multiplying the coefficient of that region, and determining a score for each area, the sum of the scores of the six regions and the GAGS scores were calculated. Total score ranges from 0 to 44, acne severity is determined according to GAGS score (0 for none, 1-18 points for mild, 19-30 for moderate, 31-38 for severe,> 39 for very severe) [7].…”

Aim: Acne vulgaris is one of the most common diseases that affects quality of life. While the Dermatology Life Quality Index (DLQI) is the most frequently used life quality index for dermatologic disorders, the Cardiff Acne Disability Index (CADI) is an acne-spesific quality of life scale. The aim of this study was to determine which scale should be more appropriate and practical to evaluate the quality of life in acne patients and to compare the differences between two scales. Methods: Acne scores of 273 patients who were admitted to the dermatology outpatient clinic between December 2015 and November 2016 were determined by the Global Acne Grading System (GAGS) (range 0 to 44). The DLQI (range 0 to 30) and CADI scores (range 0 to 20) were calculated to evaluate the effect of patients' quality of life. Results: The mean GAGS score of the patients was 20.3, and the mean of CADI score was 6.1, while the mean of DLQI was 6.0. There was a significant positive correlation between total GAGS score and CADI and DLQI (r=0.639, p<0.001). When the relationship between the distribution of acne lesions and quality of life scales was evaluated; CADI score was significantly higher in the forehead localization group than in the non-forehead localization group (p=0.012), and the CADI and DLQI scores were higher in the upper back group than the group without back localization (p=0.001and p= 0.017 respectively). Conclusion: In our study, it was observed that the DLQI and CADI scales were not superior to each other in evaluating the quality of life in patients with acne. Besides, we think that the effect of quality of life on facial acne cases can be determined more clearly with CADI scale.
