ABSTRACT

Background:

Acne is a common skin condition that is most prevalent in young people. It can have substantial impact on quality of life, which can be minimised with appropriate use of topical treatments. Nonadherence to topical treatments for acne is common often leading to treatment failure.

Objective:

The objective of this study was to develop a web-based behavioural intervention to support self-management of acne and to assess the feasibility of recruitment, retention and engagement with the intervention.

Methods:

The intervention was developed iteratively using LifeGuide software and following the Person-Based Approach (PBA) to intervention development. The target behaviour was ‘Appropriate use of topical treatments’ and barriers and facilitators identified from the qualitative research and evidence from the wider literature were used to identify techniques to improve and promote their use. Young people with acne aged 14-25 years who had received treatment for acne within the last 6 months were invited to participate through mail-out from primary care practices in the South of England in a parallel unblinded randomised trial. Participants were automatically randomised using a computer-generated algorithm to: (1) usual care, or (2) usual care plus access to web-based intervention. Usage data was collected and a series of questionnaires including the primary outcome measure for skin specific quality of life (Skindex-16) were collected at baseline, 4-weeks and 6-weeks follow-up.

Results:

A total of 1193 participants were invited and 53 young people with acne were randomised to usual care (n=27) or usual care plus intervention (n=26). The response rate for the primary outcome measure (Skindex-16) was 87% at 4-weeks, 6-weeks or both time points. The estimate of mean scores between groups (with 95% confidence) using linear regression showed a trend in the direction of benefit for the web-based intervention group in the primary outcome measure (Skindex-16), and secondary measures (Patient Health Questionnaire 4 and the Problematic Experiences of Therapy Scale). Intervention usage data showed a high uptake of the core module in the usual care plus web-based intervention group with 23 of 26 (88%) completing the module. Uptake of the optional modules were low with less than half visiting each (Myth-busting quiz: 27%; Living with spots or acne: 42%; Oral antibiotics: 19%; What are spots or acne: 27%; Other treatments: 27%; Talking to your GP: 12%).

Conclusions:

This study demonstrated the feasibility of delivering a trial of a web-based intervention to support self-management for young people with acne. Additional work is needed prior to a full definitive trial including enhancing engagement with the intervention, recruitment and follow-up rates.
