Figure 2. Predicted Values from the Interaction between Stress Reactivity to the Trier Social Stress Task (TSST) or No-Stress Task and Average Amount of Prescription Opioids Used during Follow-Up.

Figure 2

Note: This figure demonstrates the predicted values from the multiple regression model for the interaction between stress reactivity and randomization to the Trier Social Stress Task (TSST) or to the No-Stress condition with follow-up opioid use. The model outcomes show that individuals randomized to the TSST showed variation in the number of opioid pills they used at 1-month follow-up depending on their changes in stress reactivity. Following the TSST, those with a greater change in stress reactivity (+1 SD Stress Reactivity; yellow line) consumed fewer opioid pills at one month follow up whereas those with less change in stress reactivity (−1 SD Stress Reactivity, green line) used more pills at 1-month follow-up.
