A Qualitative Investigation of the Impact of Acne on Health-Related Quality of Life (HRQL): Development of a Conceptual Model

Introduction: The negative impact of acne on aspects of health-related quality of life (HRQL) has been demonstrated in many quantitative studies; however, there has been relatively little qualitative research exploring the impact of acne and the use of topical treatment. The study aimed to explore the impact of moderate-severe acne on HRQL in adolescents and adults with inflammatory and non-inflammatory lesions and to develop a conceptual model to illustrate the impact. In addition, the study aimed to identify the attributes of topical acne treatments that are most important for patients. Methods: Thirty-four adolescents and 16 adults with moderate-severe acne who were currently/recently prescribed topical treatment were recruited in this cross-sectional qualitative study in the UK, Italy, and Germany. In-depth, semi-structured telephone interviews explored patients' experiences of acne and the impact it has on their HRQL, and their experience of topical treatments for acne. Data were analyzed using thematic analysis and a conceptual model was developed. Results: The analysis identified seven main areas of HRQL that are affected by acne: emotional functioning, social functioning, relationships, leisure activities, daily activities, sleep, and school/work. Also common throughout the interviews was the perception and reaction to acne from others, which potentially had an impact on all areas of HRQL. The conceptual model illustrates the impact on HRQL and the links between HRQL domains. For both adolescents and adults, it was most important for acne treatments to be fast-acting, non-irritating, and non-bleaching. Conclusion: The results of this qualitative study demonstrate that moderate-severe acne has an extensive impact on adolescents' and adults' HRQL. The conceptual model illustrates the many areas of HRQL that are affected and draws attention to the importance of effective treatments for acne. The study also highlights topical acne treatment attributes that are most important for patients.
