Prospective memory (PM) is the accurate execution of an intention in the future. PM may be negatively impacted by negative affect, but the underlying mechanisms remain unclear. Rumination may increase the frequency of task-irrelevant thoughts, which deplete attentional capacity and reduce performance. To date, no studies have examined state and trait rumination on an online measure of PM. The present study examined the effects of state and trait rumination on an event-based, focal PM task embedded within a one-back task over multiple sessions. 95 non-depressed adults (18-53 years) completed measures of state/trait rumination, mood, and PM on at least two occasions. Using multi-level modelling, we found that a derived measure of trait rumination, but not an established trait rumination survey, nor negative mood, predicted poorer PM accuracy. These novel findings demonstrate that trait rumination may partially underlie the association between negative affect & PM in a non-clinical sample, and highlight the potential of online methods to study PM.

Individual Rumination in Adult Cancer Care: A Concept Analysis.
Semin Oncol Nurs
January 2025
School of Nursing, Midwifery and Health Systems, University College Dublin (UCD), Dublin, Ireland.
Objective: To conceptualize rumination in adult cancer care.
Methods: Walker and Avant's concept analysis method was used to examine rumination in adults with cancer. A systematic search was conducted across psychology, nursing, medicine, and public health disciplines in PsycINFO, PubMed, Web of Science, CINAHL, and Scopus databases from their inception to April 2024.

Existing research on callous-unemotional (CU) traits and conduct problems primarily focuses on the concurrent or unidirectional associations between these constructs (i.e., from CU traits to CP), with less attention given to their dynamic interplay during middle childhood.

Clin Gerontol
November 2024
Department of Dementia Research and Care Science, University for Continuing Education, Krems, Austria.
Objectives: Mindfulness-based interventions (MBIs) for persons with dementia (PwD) have yielded mixed results, possibly attributable to the fact that little is known about the validity and reliability of trait mindfulness self-report measures in PwD. This narrative review sought to identify studies involving self-reported trait mindfulness and other clinical measures that may hold information on the convergent validity and reliability of these measures in PwD.
Methods: Scientific databases were searched for studies involving PwD and mindfulness assessments.
Worry and rumination elicit similar neural representations: neuroimaging evidence for repetitive negative thinking.
Cogn Affect Behav Neurosci
November 2024
Department of Psychology, University of Miami, PO Box 248185, Coral Gables, FL, 33124, USA.
Repetitive negative thinking (RNT) captures shared cognitive and emotional features of content-specific cognition, including future-focused worry and past-focused rumination. The degree to which these distinct but related processes recruit overlapping neural structures is undetermined, because most neuroscientific studies only examine worry or rumination in isolation. To address this, we developed a paradigm to elicit idiographic worries and ruminations during an fMRI scan in 39 young adults with a range of trait RNT scores.
