Digital Support for Addiction Recovery

An app for young people, in five languages, developed in PREPARE — a five-year BMBF-funded research project led by DISuP at the Katholische Hochschule NRW.

Sole UX/UI designer in a team of seven. Concept, user flow and interaction design, interface, the multilingual design system across five languages, and the prototype the released app was built on.

01 · Problem and solution

German was the condition for getting help

Evidence-based addiction prevention existed, and it existed in German. Young people who did not read German were left outside it.

BePrepared supports young people through alcohol and cannabis addiction in Arabic, German, English, Farsi and Pashto. It tracks consumption, sets personal goals, teaches relaxation techniques and holds the reference material. Free, anonymous, available anytime.

02 · Process

Designing inside five years of addiction-prevention research

The team was one user researcher, two engineers, two psychologists and an addiction-prevention expert. I was the sole designer. Before design started, the researchers spent about a year on the domain report everything else was built on: where risk happens, what stops people from seeking help, and when a digital intervention can be trusted.

03 · Designing for multilingual adaptation

Five languages, one consistent product

The hard part was not the feature set. The same product had to work in five languages without forking into five products, so the design system had to absorb what each language demanded.

Right to left. Layout, navigation order, directional icons and progress indicators mirror for Arabic. Components were built bidirectionally from the start, not retrofitted, so the Arabic version is not a translated afterthought.

Text length. The same string changes width and height across the five scripts. Every component was sized for the worst case, so the hierarchy holds everywhere.

Tone. Addiction carries different stigma in each group. Language and imagery stay measured, with no metaphors that travel badly or imply judgement. The Arabic version was reviewed with Arabic-speaking colleagues; user testing with the target group ran through the project partners as part of the clinical protocol.

Still available after the funding window closed in 2024.
A 150-participant study
A feasibility study with the target group, surveyed at baseline, 4 weeks, 3 months and 6 months.
Five languages, one product
One design system carried all five, without forking into five products.
04 · What held

It held across the hardest audience to keep

Keeping participants in a multilingual study over six months is materially harder than a general-population sample. The design held across five languages and that timeframe.
