Understanding this bias could help inform interventions to address cognitive distortions in this population.MethodsA total of 234 breast cancer patients were assessed for PTSS using the Impact of Event Scale (IES). Based on their PTSS status, 40 participants were randomly selected from both PTSS-positive and PTSS-negative groups, resulting in 80 participants. All participants completed an ambiguous facial expression judgment task.ResultsThe PTSS group showed significantly higher proportions of “sad” judgments and longer reaction times than the non-PTSS group across all levels of facial expression ambiguity, suggesting increased cognitive load when interpreting ambiguous emotional stimuli.ConclusionBreast cancer patients with PTSS exhibit a marked negative interpretation bias, which may exacerbate cognitive distortions. These findings highlight the importance of addressing interpretation biases in therapeutic interventions for this population.
