Depression remains one of the leading causes of disability worldwide, affecting millions and reducing quality of life for many. A new study from the Chinese University of Hong Kong suggests that self-compassion, the ability to treat oneself with kindness in the face of failure or distress, may play a crucial role in protecting people from depressive symptoms. The research, published in Psychreg Journal of Psychology, highlights that this protective effect is largely explained by the way people regulate their emotions.
The study involved 300 Chinese adults aged between 18 and 70, who completed questionnaires measuring levels of self-compassion, emotion regulation strategies, and depressive symptoms. The researchers investigated two common strategies: expressive suppression, where individuals hide their emotions, and cognitive reappraisal, which involves reframing negative experiences in a more positive light.
Findings showed that people with higher levels of self-compassion reported fewer depressive symptoms, and this was strongly linked to a reduced tendency to suppress their emotions. In contrast, cognitive reappraisal did not appear to explain the connection between self-compassion and depression. This suggests that while reframing negative thoughts can be useful, it is the avoidance of emotional suppression that makes the most difference.
Tsz-Wah Ma, PhD a lecturer from the Chinese University of Hong Kong and lead author of the study, explained the motivation for the research: “Depression remains a leading cause of disability worldwide, yet the mechanisms linking protective factors like self-compassion to depressive symptoms are not fully understood. While prior research consistently highlights the negative association between self-compassion and depression, the specific pathways, particularly the role of emotion regulation strategies, remain underexplored. This study aimed to bridge this gap by investigating whether adaptive cognitive reappraisal and maladaptive expressive suppression emotion regulation strategies mediate this relationship.”
Expressive suppression, the act of concealing feelings, has long been associated with poor mental health outcomes. Although hiding emotions may seem like a way to avoid distress in the short term, over time it can worsen negative emotions and limit positive ones. The study reinforces this, showing that suppression accounted for almost a third of the relationship between low self-compassion and higher depressive symptoms.
According to Ma, the findings provide important clinical insight: “Our findings revealed that expressive suppression, a maladaptive emotion regulation strategy, significantly mediated the link between self-compassion and depressive symptoms. Higher self-compassion was associated with reduced use of expressive suppression, which in turn predicted lower depressive symptoms. Surprisingly, cognitive reappraisal did not emerge as a significant mediator, suggesting that self-compassion’s protective effects may operate more through reducing harmful suppression than through enhancing cognitive reframing. These results underscore the importance of addressing expressive suppression in therapeutic settings, such as through mindfulness-based interventions that encourage emotional acceptance rather than concealment.”
By contrast, self-compassion seems to encourage people to face their emotions rather than avoid them. Approaching difficulties with kindness and recognising them as part of the shared human experience can reduce self-criticism and foster resilience. This makes self-compassion a potentially valuable tool in reducing the risk of depression, particularly for those who habitually suppress how they feel.
While the research strengthens the evidence linking self-compassion with better mental health, it also highlights some limitations. The findings were based on a cross-sectional survey, meaning that while strong associations were found, the study cannot prove cause and effect. It is also possible that depression itself may reduce people’s ability to be self-compassionate, making the relationship a complex one.
Looking ahead, Ma noted the importance of extending this line of inquiry: “Moving forward, we plan to expand this research through longitudinal studies to establish causal relationships and explore how these mechanisms unfold over time. Additionally, we aim to replicate these findings in clinical populations, such as individuals diagnosed with major depressive disorder, to test their applicability in more severe cases. Future research will also investigate other emotion regulation strategies, like acceptance or savouring, to provide a more comprehensive understanding of self-compassion’s role in mental health.”
Despite these limitations, the results add weight to the idea that self-compassion could be incorporated into mental health interventions. Programmes such as mindfulness training and compassion-focused therapy already draw on these principles, and further testing in clinical settings could determine their effectiveness for people with depression.
The findings also suggest that public health strategies promoting emotional openness rather than suppression could help reduce depressive symptoms across communities. Teaching people to relate to themselves with kindness may prove to be a simple yet powerful way to build resilience against one of the most common mental health issues worldwide.
