What this trial studies

This pilot interventional project delivers dialectical behaviour therapy–informed skills training via the internet, with monthly health education as a comparator/support. It enrolls Hong Kong Chinese adults aged 18–64 who smoke daily, report psychological distress on the DASS-21, intend to stop smoking, and have internet access. Outcomes include feasibility and acceptability measures, preliminary effects on smoking abstinence or reduction and on psychological distress and emotional regulation, plus qualitative interviews about participants' experiences. The design emphasizes remote delivery to increase accessibility while recruiting through Hospital Authority sites in Tai Po and Hong Kong.

Who should consider this trial

Good fit: Ideal candidates are Hong Kong Chinese adults aged 18–64 who smoke at least one cigarette daily, have elevated distress on the DASS-21, want to quit, and can use internet-capable devices.

Not a fit: People with psychotic disorders, significant cognitive or communication impairments, those already in other smoking cessation programs, or those without internet access are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the program could provide an accessible online option to help smokers with emotional distress quit or reduce smoking and improve emotional regulation.

How similar studies have performed: Previous DBT-informed and internet-based smoking interventions have shown promise for people with emotional dysregulation, but fully online DBT skills training specifically for smoking cessation is relatively novel and less studied.
