Web-Based Mindfulness-Based Interventions for Well-being: Randomized Comparative Effectiveness Trial.

Area of Science:

• Psychology
• Clinical Psychology
• Behavioral Science

Background:

• Mindfulness practice enhances well-being by focusing on the present without judgment.
• The optimal duration and intensity of mindfulness training for well-being improvement remain unclear.

Purpose of the Study:

• To compare the efficacy of an 8-session web-based Mindfulness-Based Cognitive Therapy (MBCT) program against a brief 3-session mindfulness intervention in improving overall well-being.
• To investigate if baseline participant characteristics moderate treatment effects.

Main Methods:

• 4411 participants were randomized to either standard 8-session MBCT or brief 3-session mindfulness training.
• Well-being was assessed using the World Health Organization-Five Well-Being Index over a 20-week period.
• Moderators of treatment effect were explored based on participant characteristics.

Main Results:

• Both MBCT and brief mindfulness interventions significantly increased well-being.
• No significant difference in well-being improvement was found between the 8-session MBCT and the 3-session intervention.
• Younger participants and those with higher session completion rates showed greater well-being improvements, particularly in the MBCT group.

Conclusions:

• Standard MBCT and brief mindfulness interventions are effective in improving well-being.
• Shorter mindfulness programs can provide substantial benefits to a general population with diverse medical conditions.
• MBCT may be more beneficial for younger individuals and those highly adherent to treatment.
