RESUMEN
Background: The COVID-19 pandemic has resulted in many individuals experiencing increased symptoms of anxiety. We predict that this increase may be underpinned by pandemic-related worry (PRW), characterised by repetitive negative thinking about pandemic-specific outcomes; and that this relationship is mediated through reduced attentional capacity required to regulate negative affect. Methods: We developed a novel scale to measure the contents of PRW in an initial sample of 255 participants, and explored its relationship with cognitive functioning and negative affect in a sample of 382 UK-based university students, whilst controlling for recalled pre-pandemic trait anxiety. Results: A five-factor model of PRW was identified, with factors reflecting worry about decline in quality of life (QoL) and probability of infection correlating with attention and memory-related errors. Importantly, attention-related errors partially mediated the positive relationship between PRW and negative affect, even when controlling for pre-pandemic trait anxiety. Conclusion: PRW's relationship with negative affect was partially mediated through attentional function, consistent with models of anxiety and attentional control. In UK-based students PRW may be predominantly focused on the decline in QoL; therefore, interventions targeting worry about the decline in QoL caused by COVID-19 are especially important in this population in the wake of the pandemic.

RESUMEN
Worry, a stream of negative thoughts about the future, is maintained by poor attentional control, and the tendency to attend to negative information (attention bias) and interpret ambiguity negatively (interpretation bias). Memories that integrate negative interpretations (interpretation-memory) may also contribute to worry, but this remains unexplored. We aimed to investigate how these cognitive processes are associated with worry and anxiety cross-sectionally (Phase 1), and then explore which cognitive processes from Phase 1 would predict worry and anxiety during times of high stress, namely prior to examinations (Phase 2), and after the initial onset of the COVID-19 pandemic (Phase 3). Worry, anxiety, and cognitive processes were assessed in an undergraduate sample (N = 64). We found that whilst greater benign interpretation bias and benign interpretation-memory bias were associated with lower levels of concurrent worry and anxiety, only interpretation bias explained unique variance in worry and anxiety. No cognitive predictor significantly explained unique variance in prospective worry and anxiety prior to examinations. In relation to anxiety and worry during the stress of the COVID-19 pandemic, both benign attention bias and benign interpretation-memory bias predicted decreased worry; only benign attention bias predicted decreased anxiety. Findings suggest that cognitive processes can predict changes in worry and anxiety during future stressful contexts.

Worry and rumination are forms of repetitive negative thinking (RNT) that are maintained by negative interpretations and a predominance of abstract, verbal thinking. Hence, facilitating more positive interpretations and imagery-based thinking in combination may reduce RNT. Study 1 administered interpretation training with and without enhanced imagery, and an active control condition (designed not to change interpretations), in individuals with high levels of RNT (worry and/or rumination). Combining interpretation training with sustained imagery resulted in the highest levels of positive interpretation bias using an offline test of interpretation bias (when individuals have time to reflect). Study 2 investigated whether imagery-enhanced interpretation training influences online interpretations when ambiguous information is first encountered, indexed by reaction times and amplitude of the N400 event-related potential, as well as enhances offline positive interpretations in high worriers. It also examined whether imagery-enhanced interpretation training reduces negative thought intrusions associated with worry. Both online (reaction time) and offline interpretations were more positive following imagery-enhanced interpretation training, and negative thoughts were reduced, compared to the active control. However, no differences emerged on neurophysiological markers during the online task. Hence, brief interpretation training encompassing sustained imagery modifies online and offline interpretations, but further training may be required to impact upon neurophysiological measures.

The tendency to interpret ambiguous information in a consistent (e.g., negative) manner (interpretation bias) may maintain worry. This study explored whether high and low worriers generate different interpretations and examined at which stages of information processing these interpretations can occur. Participants completed interpretation assessment tasks yielding behavioural and N400 event-related potential indices, which index whether a given interpretation was generated. High worriers lacked the benign interpretation bias found in low worriers. This was evident for early "online" interpretations (reflected in reaction times to relatedness judgments and lexical decisions, as well as at a neurophysiological level, N400, for lexical decisions only), to later "offline" interpretations (observed at a behavioural level on the scenario task and recognition task) when participants had time for reflection. Results suggest that a benign interpretation bias may be a protective factor for low worriers, and that these interpretations remain active across online and offline stages of processing.
