Means, SDs, and Observed Pearson Correlations Among all Self-Reported Variables Hypothesized to Correlate With the API in FAP Participants at Baseline
| API | CSI | PBQ | FDI | CDI | |
|---|---|---|---|---|---|
| Somatic symptoms (CSI) | 0.46 | ||||
| Pain threat (PBQ) | 0.56 | 0.52 | |||
| Functioning (FDI) | 0.36 | 0.60 | 0.44 | ||
| Negative affect (CDI) | 0.29 | 0.52 | 0.45 | 0.52 | |
| Mean SD | 1.93 0.87 | 0.67 0.42 | 1.92 0.71 | 0.75 0.66 | 0.70 0.53 |
Note. API = Abdominal Pain Index; CSI = Children’s Somatization Inventory; PBQ = Pain Beliefs Questionnaire; FDI = Functional Disability Inventory; CDI = Children’s Depression Inventory. All correlations were significant at p < .001.
