Summary: Researchers recruited 10 pregnant adult women who smoked at least weekly via charities, clinics, web forums, and community websites, to evaluate usability of SmokeFree Baby. Participants used the full app for about 30 minutes and described their thoughts to researchers. Participants appreciated the app’s aesthetic appeal, blue theme color, intuitive navigation, and interactive intervention components, both online and offline (e.g. helpline phone numbers). Participants appreciated that intervention content featured information relevant to tobacco-use during pregnancy while focusing on the ultimate objective: child protection. Participants highlighted features that allowed them to document progress (e.g. video diary) and receive professional advice (e.g. videos from smoking cessation advisors). Participants found the app’s featured ex-smoker relatable, but recommended researchers include multiple pregnant ex-smokers, to expose users to diverse perspectives and life experiences. Visual presentation of smoke-free days and social support features (e.g. a loved one’s voice memo) motivated participants to remain abstinent, while display of monetary savings from abstinence received mixed feedback. Some participants felt the content for coping with cravings and diversion would be impractical at times of temptation and insufficient for sustained abstinence. Participants felt a larger font size, a more varied (or customizable) color palette, and highlighting useful intervention components would improve design. Participants also suggested frequent intervention content updates, more concise content segments, and user-tailored intervention content to promote engagement.
Take Away: Participant feedback about the design, navigation, and content of SmokeFree Baby was positive overall, but included suggestions for accessibility and user engagement improvements.
