From Self to Others? Testing Whether Brief Mindfulness Reduces Intergroup Bias through Decentering or Self-Compassion

PsyArXiv September 28, 2026 Gabriela Górska, Paweł Holas preprint

AbstractBrief mindfulness reliably changes how individuals relate to their own internal experiences, but whether these intrapersonal changes generalize to intergroup responding remains unclear. This preregistered experiment (N = 91) examined whether mindfulness-related processes—decentering and compassionate self-responding—were associated with socio-affective responses toward in-group and...

Efficacy and mechanisms of internet-delivered mindfulness-based cognitive therapy for Adjustment Disorder: A randomized controlled trial.

Journal of Anxiety Disorders July 1, 2026 Paweł Holas, Jan Wardęszkiewicz, Malgorzata Grochowska et al.

Adjustment Disorder (AjD) is a common stress-related condition, yet evidence-based interventions remain scarce. Mindfulness-Based Cognitive Therapy (MBCT) targets transdiagnostic mechanisms such as cognitive fusion and low self-compassion, which may be particularly relevant for AjD.

Attentional processes in brief mindfulness meditation and socio-affective responses to in-group and out-group suffering.

Acta Psychologica June 1, 2026 Gabriela Górska, Paweł Holas

Empathy and compassion often arise in response to others' suffering but can be inhibited when the sufferers represent out-groups. Mindfulness meditation may help counter these blocks by reducing distress and fostering compassionate responses. In this study, we tested whether a brief, 10-min mindfulness intervention could enhance empathic and compassionate reactions to in-group and out-group...

The Mediating Role of Mindfulness and Self-Compassion in the Link between Tinnitus Distress and Anxiety.

Audiology & neuro-otology March 12, 2026 Weronika Caban, Paweł Holas, Mikołaj Kuncewicz et al.

Introduction: Tinnitus is the perception of sound in the absence of external stimuli, often experienced as ringing or buzzing. While many individuals habituate to tinnitus, others develop chronic tinnitus (CT), which can severely affect emotional well-being. Psychological mechanisms such as anxiety and maladaptive coping are known contributors to tinnitus distress, yet the protective role of...

Effects of brief mindfulness meditation on compassion and personal distress using the socio-affective video task.

Scientific Reports August 22, 2025 Gabriela Górska, Paweł Holas

Recent findings indicate that meditation may enhance compassion and foster prosocial actions aimed at helping others. In the present preregistered research, we aimed to test hypotheses regarding the positive impact of a single short, guided mindfulness meditation on compassionate and personal distress responses, measured with the Socio-affective Video Task (SoVT), and the possible mechanisms of...

The interplay between self-compassion and mindfulness in the explanation of depression and anxiety in depressed individuals

Archives of Psychiatry and Psychotherapy July 14, 2025 Patryk Roczon, Paweł Holas, Marzena Rusanowska et al.

Previous studies have found that self-compassion and mindfulness are negatively related to depressive and anxiety symptoms. Still, the mechanisms underlying these relationships in major depression and whether such mechanisms differ in healthy people are poorly understood. In the present study, it was examined whether mindfulness and worrying mediated relationships between self-compassion,...

I-mindfulness-based cognitive therapy (i-MBCT) in the treatment of COVID-19 related adjustment disorder. a RCT study with active control group

European Psychiatry April 1, 2021 Paweł Holas

Introduction Adjustment disorder (AD) is described as a maladaptive reaction to an identifiable psychosocial stressor/s that usually emerges within a month after the onset of the stressor. With all uncertainty, fears and disorientation, it’s no surprise that many people have developed an AD linked to the sudden changes brought about by COVID-19, such as threat to life, imposed restrictions, and...

Modification of Attentional Bias to Emotional Faces Following Mindfulness-Based Cognitive Therapy in People with a Current Depression

Mindfulness June 1, 2020 Paweł Holas, Izabela Krejtz, Katarzyna Wisiecka et al.

Abstract Objectives Mindfulness-based cognitive therapy (MBCT) is an evidence-based treatment to prevent relapse in individuals with recurrent major depressive disorder (MDD). It is not clear if MBCT is an effective therapy for current depression, and it is not clear what mechanisms are responsible for the effectiveness of MBCT. Theoretically, MBCT is believed to modify the processing of...

Effects of Brief Mindfulness Meditation on Attention Switching

Mindfulness February 10, 2020 T. Jankowski, Paweł Holas

Attention switching is postulated in many theories as a crucial executive function related to mindfulness. However, the existing literature does not provide convincing support for this claim. Based on the attentional control theory, the presented experiment tested the hypothesis that brief mindfulness training improves attention switching in the presence of anxiety. Seventy-four undergraduates...
