Associations with ERP measures among patients
| Variable | Association with ERN | Association with Pe | ||
|---|---|---|---|---|
| Correlation (r) | Adjusted (β) | Correlation (r) | Adjusted (β) | |
| Symptoms—Total Scores | ||||
| Negative | −.22* | −.27* | −.21† | .08 |
| Psychotic | −.13 | −.03 | −.15 | −.07 |
| Disorganized | −.09 | −.10 | −.10 | .00 |
| Real World Functioning | ||||
| Rehospitalizations, Years 0–4 | −.23* | −.25* | .08 | .14 |
| Rehospitalizations, Years 4–10 | −.03 | −.02 | −.12 | −.02 |
| Unemployed | −.34** | −.34** | −.20† | −.04 |
| Socially Impaired | −.07 | −.03 | −.16 | .13 |
| Neuroticism | .27** | .26* | −.11 | −.11 |
| Post-Error Slowing | −.10 | −.05 | −.11 | −.08 |
Note: Adjusted values include diagnosis (SZ vs. OP), age, gender, ethnicity, antipsychotic medication status, premorbid IQ, and socioeconomic status as additional predictors. ERN amplitude was converted to a positive number, such that positive regression coefficients indicate a direct association and negative coefficients indicate an inverse association. Post-error slowing is the reaction time difference between correct trials following errors and the average of all correct trials.
