Condensation and validation of a 4-item index of the Acne-QoL

Abstract

The Acne-Q(4) is accurately reflective of the parent instrument and may facilitate the psychometric evaluation of the impact of facial acne on patients in routine clinical practice by its practicality.

Acne severity grading: Determining essential clinical components and features using a Delphi consensus

“…Such patientcentric measures are routinely included as a complement to clinician-based global acne severity assessments in clinical trials. [20][21][22][23][24][25] Future researchers may wish to evaluate whether clinicians who do not conduct research would find the inclusion of patient experiences useful for an ideal acne severity scale.…”

Divergence of Demographic Factors Associated with Clinical Severity Compared with Quality of Life Impact in Acne

“…1 In our modeling of Acne-QoL determinants, the rank order of factors was clinical severity, duration of acne, gender, and age. Previous studies have shown that the correlation of clinical grading and QoL measures has been either weak or none, depending on whether the QoL instruments used were specific 1,3,7,11 or more general, respectively. [12][13][14] Our findings concur with the concept that these two measures are complementary but dissimilar.…”

“…The relevant questions relate to dissatisfaction with appearance, feeling upset, concern about meeting new people, and concern about scarring. 11 In addition to providing a patient-centered perspective, disparate QoL scores may assist clinicians in identifying patients at risk of psychiatric disturbances, such as depression or body dysmorphic disorder. Subsequent management of such patients will then appropriately require prioritization to focus therapy primarily on acne, the psychiatric disorder, or both concurrently.…”

“…The Acne-QoL total score is the sum of all 19 items and represents the overall acne-related QoL based on the 4 domains. 11 Sociodemographic factors considered to be potentially relevant for this analysis included age, gender, and duration of acne. Correlations of IGA and Acne-QoL scores with these factors were evaluated by nonparametric techniques (Mann-Whitney U test for two groups and the Kruskal-Wallis test for three or more groups) for IGA scores, whereas tests for comparison of mean total AcneQoL scores (ranging from 19 to 133) among different groups were based on tests appropriate for continuous variables.…”

Acne Smart Club: An Educational Program for Patients with Acne

“…Acne is a disease that can have negative consequences on the patients' psyche, which can cause depression and loss of self-esteem with important effects on their social life [11,12,13,14,15]. Since acne is a chronic disease, it typically requires prolonged treatment.…”
