Note: Reported are uncorrected P-values and test statistics of either χ2-tests for categorical variables or Kruskal–Wallis tests for all other variables for healthy controls (HC) or patients with psychotic disorders (PSY), participants without (JTC−) or with (JTC+) jumping-to-conclusion bias (decision after fish), patients with low (D−) or high (D+) current delusions (split half based on median of Psychotic Symptom Rating Scales (PSYRATS)36: Delusion subscale), and patients without (R−) or with (R+) treatment response to Metacognitive Training17 defined as at least 20% decrease in the Positive and Negative Syndrome Scale (PANSS)38 positive factor39 compared to baseline. P: Positive symptoms. N: Negative symptoms. G: General symptoms. E: Excitement. Ds: Distress. Do: Disorganization. D: Delusions. H: Hallucinations. Bold values indicate p-values significant at p<0.05.
