The effect of a brief mindfulness-based intervention on personal recovery in people with bipolar disorder: a randomized controlled trial (study protocol)

BMC Psychiatry August 22, 2019 Sunny Ho‐Wan Chan, Samson Tse, Ka Fai Chung et al. 8 citations

A protocol for a randomized controlled trial will test whether a brief mindfulness-based intervention (MBI) of four sessions helps adults with bipolar disorder improve personal recovery—encompassing hope, identity, and life meaning—more than a waiting list control. The study hypothesizes that benefits will be mediated by better emotion awareness, emotion regulation, and illness acceptance, and that the stage of bipolar disorder will moderate effects: early-stage participants may gain more in emotion awareness and regulation, while late-stage participants may benefit more in illness acceptance. One hundred fifty-four adults will be recruited from hospitals and community settings, with assessments at baseline, after intervention, and at six-month follow-up, plus a qualitative Photovoice component.

Differential effects of mindfulness and grit on positive mental health outcomes in major depressive and bipolar disorders: A moderation analysis using an ecological momentary assessment approach.

Journal of Affective Disorders July 23, 2025 Joyce Xu Hao Jin, Heidi Ka Ying Lo, Iris Wai Tung Tsui et al. 2 citations

In people with major depressive disorder (MDD) and bipolar disorder (BD), positive psychological traits such as mindfulness and grit interact with negative affect to influence positive mental health. Over two weeks, 29 people with MDD, 29 with BD, and 30 healthy controls reported their negative affect, pleasure attainment, and meaning in life five times daily. Lower negative affect strengthened the link between mindfulness and meaning in life in the MDD group but not in the BD or control group. Higher grit reduced the harmful effect of negative affect on pleasure attainment in the BD group but not in the other groups. These findings highlight complex relationships between positive traits and mental health in mood disorders.
