BANERJEE Nilosmita., CHEN Zhang., CLARK Luke., NOËL Xavier. Behavioural expressions of loss-chasing in gambling: A systematic scoping review NEUROSCI BIOBEHAV REV 152(1) XXX-XXX, 2023. - Loss-chasing, the tendency to continue and/or intensify gambling following losses, is a key clinical symptom in gambling disorder and a central feature endorsed by at-risk problem gamblers. Despite its centrality, loss-chasing has been often operationalised across distinct behavioural expressions. The current systematic scoping review aimed to map the heterogeneous operationalisations of loss-chasing in the literature. The reviewed studies defined loss-chasing either between-sessions (n = 39) or within-sessions (n = 38), as a long-recognised distinction. For both categories, further behavioural expressions could be distinguished. Between-session loss-chasing was captured by endorsing an item 'returning another day/time to recoup losses', or behaviourally as the interval between successive sessions, or as increasing stakes in the next session. Within-session loss-chasing was defined as continuing and/or intensifying gambling either by increased risk-taking, stake size, or speed of play. Additionally, much heterogeneity was observed in the gambling contexts examined, the exact definition of loss, and the potential delineation of win-chasing. Open questions and future directions are discussed. Overall, this paper serves as a first step towards more conceptual clarity of loss-chasing.
