BACKGROUND: Although aggravating effects of rumination on dysfunctional cognitions and endocrine stress responses have been proposed, experimental studies testing these assumptions are lacking.

• Self-focused rumination links stressful events to depressive and anxiety symptoms in older adults with depressive symptoms: path and network analyses (2026) · doi

  Whilst previous work has examined the pathways from external stressors to psychiatric symptoms70 and the role of rumination as a central symptom between mental health domains71, a major strength of the present study was the use of a large community sample of older adults to examine the role of rumination in relation to different types of external events and two common internalising symptoms in a single network model. The use of two complementary methodological approaches, alongside the consistent findings across the sensitivity analyses, provided further evidence supporting self-focused rumination as a robust bridging factor between external factors and internalising symptoms. This observation has important clinical implications. Emerging evidence suggests that, by targeting rumination as an underlying process, both mindfulness- based cognitive therapy72 and metacognitive training73 are effective in reducing depressive symptoms among older adults. WhWhile rumination-focused cognitive-behavioural therapy has been shown to be effective in reducing rumination and improving mental health outcomes among young and middle- aged adults 9,74, whether it could also be adapted to target older adults remains to be further investigated. Future work may continue to build on these findings to examine the efficacy of rumination-focused interventions for older adults with heightened mood symptoms. Separately, a recent study has demonstrated the efficacy of a personalised depression prevention programme in reducing the experience of dependent stressors75, which may be a plausible approach to weakening the stressor–depression loop and reducing depressive symptoms. While independent stressors may not be entirely preventable, supporting people in developing more adaptive cognitive, behavioural, or emotional approaches in the face of stressful life events beyond engaging in rumination or worry could be helpful. Aside from these strengths, the present findings should be interpreted in light of several limitations and considerations. First, as in other studies on mental health services (ref), the sample presented to the JoyAge service was predominantly female, which might have been due to lower help-seeking intention and lower preference for emotional disclosure commonly reported in males74. While our exploratory analyses revealed no clear differences between genders in depressive symptoms, self- focused rumination, and the number of SLEs experienced, as well as in their network structures, female participants in our sample presented more severe generalised anxiety symptoms. Further, older men have consistently shown leading rates of suicide deaths 78. As such, the extent to which the present findings can be generalised to a larger male population needs to be further investigated. Replicating the present research questions in other populations with more balanced gender ratios may inform more targeted intervention strategies in future servic

• Trauma‐related rumination mediates the effect of naturally occurring depressive symptoms but not momentary low mood on trauma intrusions (2014) · doi

  Future research is warranted to better understand the role of rumination in the depression–intrusion relationship, which may shed light on the clinical applicability of rumination‐targeted intervention for PTSD and comorbid depression.

• Rumination, anxiety sensitivity, and negative reinforcement drinking (2010) · doi

  Conclusions: Rumination, conceptualized as a maladaptive coping response for emotional regulation, warrants further study in relation to NRD and in developing treatment interventions for high anxiety, at-risk drinkers.

• The effect of mindfulness training on rumination and intrusions after analogue trauma (2019) · doi

  Future research should examine whether trauma‐related rumination constitutes a process of change using more intensive training of mindfulness‐based interventions for post‐traumatic stress disorder.

  Moreover, it highlights the role of rumination as a significant moderator in the relationship between over-adaptation and subjective well-being, suggesting avenues for further investigation into individual psychological coping mechanisms.
