Average Reactivity Change Scores by Stress Condition (N = 31)
| TSST (n = 16) | No-Stress (n = 15) | |
|---|---|---|
| Laboratory Task | Mean (SD) | |
| Stress condition (TSST/No-Stress) | ||
| Stress* | 4.31 (3.14) | −0.60 (1.68) |
| Craving* | 2.13 (3.01) | −0.27 (1.03) |
| DHEA* | 109.30 (102.94) | 23.81 (67.84) |
| Cortisol* | 0.15 (0.25) | −0.03 (0.08) |
| TSST/No-stress condition plus Opioid Cue Paradigm | ||
| Stress | 2.44 (3.90) | 1.93 (1.94) |
| Craving | 3.38 (2.28) | 3.33 (1.88) |
| DHEA | 119.88 (150.21) | 96.45 (99.28) |
| Cortisol | 0.07 (0.13) | 0.06 (0.15) |
| Opioid Cue Paradigm | ||
| Stress* | −1.88 (2.78) | 2.53 (2.20) |
| Craving* | 1.25 (1.98) | 3.60 (1.76) |
| DHEA | 10.39 (133.80) | 72.64 (100.43) |
| Cortisol* | −0.08 (0.22) | 0.09 (0.14) |
Note: Mean changes scores included in the survival analysis by group assignment to the Trier Social Stress Task (TSST) or the No-Stress condition. For example, the first row shows the average change score for individuals following the stress condition (either randomization to the TSST or No-Stress task). Participants who were randomized to the TSST showed an average change score of M=4.31 (SD = 3.14), suggesting increases in stress following the TSST. Oneway ANOVAs tested for group differences.
