Mindfulness-Based Integrative Programme: The effectiveness, acceptability, and predictors of responses to a novel low-dose mindfulness-based intervention.

Mindfulness-Based Interventions (MBIs) have shown promising results in improving mental health in the general population. However, traditional MBIs require substantial time and effort due to the high dose of mindfulness practice, which makes them inaccessible to many individuals. This study aimed to (1) test the effectiveness of a novel low-dose MBI-Mindfulness-Based Integrative Programme (MBIP)-delivered synchronously online, on mental health symptom severity, emotion regulation, and trait mindfulness in the general population; (2) test the acceptability of this intervention; and (3) identify baseline characteristics that may predict changes in emotion regulation. A non-randomised controlled trial design was used to compare pre- to post-intervention change scores in trait mindfulness (FFMQ), mental health symptom severity (SCL-90-R GSI), and emotion dysregulation (DERS) between a self-selected and self-paid experimental group (n = 116) and a passive control group (n = 115). The experimental group showed significant increases in trait mindfulness and reductions in mental health symptom severity and emotion dysregulation, with effect sizes ranging from small to large, which is comparable to traditional in-person MBIs. Baseline trait mindfulness and mental health symptom severity significantly predicted intervention outcomes, with greater improvements in emotion regulation among participants with lower baseline scores. Participants demonstrated high levels of engagement and reported high satisfaction with the intervention. These findings support the acceptability and effectiveness of a novel low-dose, synchronous online MBI for the general population.
