Trait worry is a hallmark feature of anxiety and depression, interfering with attentional control and impairing cognitive performance. Previous research has shown the adaptive dual n-back training is effective in improving attentional control and reducing emotional vulnerability, but not for everyone. The current randomised controlled trial explored the role of baseline emotional vulnerability and perceived cognitive impact in training-related cognitive and emotional improvements in 60 high worriers randomly assigned to 10 sessions of the adaptive dual n-back training or non-adaptive 1-back training. Pre-training, post-training and one-month follow-up measures of cognitive performance were assessed using an emotional Flanker task, a cued task-switching task, and the MaRs-IB task. Self-report questionnaires assessed worry, anxiety, depression, somatisation, and self-efficacy, as well as participants’ perceived cognitive impact of the training. Participants with higher levels of baseline emotional vulnerability presented the largest improvements in non-verbal reasoning and emotional vulnerability one month after the training, as well as the greatest perceived cognitive impact. Perceived cognitive impact was predicted by working memory improvement on the adaptive n-back training at high baseline levels of anxiety. These results suggest that the adaptive n-back training presents the greatest emotional and cognitive benefits for individuals experiencing severe levels of emotional vulnerability.

Rumination is an established transdiagnostic factor in mental illness, but there remains a significant gap in understanding the subjective experiences of those affected by it. This study explored the lived experiences of depressive rumination in early adulthood, a population notably susceptible to its effects. We interviewed 20 participants aged between 18 and 35 years using a semistructured approach and generated five distinct but interconnected themes using reflective thematic analysis. The first theme delved into recurrent narratives of past traumas and unresolved pain, with participants unable to move on from their past. The second theme illustrated how participants, due to real or perceived pressure, often equated their self-worth with their ability to meet expectations, leading to a distorted self-view and diminished self-esteem. The third theme captured the relentless pursuit of mental peace, with tranquility remaining ever elusive despite the frequent use of distraction. The fourth theme highlighted the profound isolation stemming from internalized mental health stigma, with participants grappling with fears of being perceived as burdensome and facing rejection from their close ones. Finally, the fifth theme underscored the far-reaching and interconnected repercussions of rumination on mental, emotional, and physical health and individuals’ ability to achieve their life goals. These findings emphasize the intertwined nature of psychological, physiological, and social risk factors for the development and maintenance of rumination, advocating for a holistic treatment approach to rumination and paving the way for more timely, tailored care.
