The role of attentional biases in the context of cancer: A systematic review and meta-analysis
A partir d'une revue systématique de la littérature (18 articles), cette méta-analyse évalue la présence de biais d'attention chez des patients ayant survécu à un cancer et l'association entre ces troubles et une détresse psychique
Objective : Little is known about the role of attentional processes in the context of cancer. This systematic review aimed to (1) synthesize the literature on attentional biases in cancer survivors; and (2) assess if these biases are associated with indicators of psychological distress. Method : Studies were identified through a systematic search in PsycINFO, Medline, Scopus, CINAHL, Web of Science and Embase databases. We included studies that examined attentional biases using an accepted experimental paradigm (Dot‐probe or Stroop) in cancer survivors. Results : Of 4105 papers identified, 18 met inclusion criteria. Cancer survivors had a greater attentional bias towards salient stimuli (cancer/negative stimuli) as compared to controls (Hedge's g= 0.82). Survivors who were more distressed had greater attentional biases (Hedge's g= 0.27). It was unclear whether the nature of stimuli was important in driving these effects (e.g. cancer‐specific versus negative). Conclusion : These results demonstrate that cancer survivors have an attentional bias towards cancer‐related (typically words) or negative stimuli (typically facial expressions), and that bias is greater for those with higher levels of distress.
