Jumping to Conclusions Style along the Continuum of XXXX : Delusion-Prone Individuals Are Not Hastier in Decision Making than Healthy Individuals.

@entity1 @entity8143
UNASSIGNED: Literature comparing 'jumping to conclusions' (JTC) between @entity1 and healthy controls has demonstrated the importance of the reasoning bias in the development of delusions. When groups that vary along the entire delusional continuum are included, the relationship between JTC and delusionality is less clear. This study compared JTC and delusional dimensions between 28 @entity1 with delusions, 35 delusion-prone individuals and 32 non-delusion-prone individuals. Delusion proneness was defined by an established threshold based on the Peters et al. @entity8143 Inventory. Two versions of the beads task (85:15 and 60:40) were used to measure JTC. As hypothesized, @entity1 manifested hastier data gathering than the two non-clinical groups on both beads tasks. However, delusion-prone individuals did not manifest a hastier decision making style than non-delusion prone individuals. Instead, non-delusion-prone @entity1 showed more JTC bias than delusion-prone individuals on the easier beads task. There was no evidence for a dose-response relationship between JTC and delusional dimensions, with correlations between JTC and PDI scores found in the non-delusion-prone group only. The present finding confirms the link between an extreme JTC bias and the presence of clinical delusions, and argues against a linear relationship between JTC and delusionality along the symptomatic continuum.
