Fig. 1. Interaction between distress and viral load for helper T-cell count. Low and high plots represent values 1 standard deviation above or below the mean for both viral load and the distress index. The standardized coefficient for distress at low viral load was ß = -0.28, p < .05.

Fig. 2. Interaction between the distress and viral load for the memory helper T-cell subset count. Low and high plots represent values 1 standard deviation above or below the mean for both viral load and the distress index. The standardized coefficient for distress at low viral load was ß = -0.26, p < .05.

Fig. 3. Interaction between distress and viral load for B-cell count. Low and high plots represent values 1 standard deviation above or below the mean for both viral load and the distress index. The standardized coefficient for distress at low viral load approached significance (ß = -0.30, p = .06) but was significant at 1.5 standard deviations (ß = -0.42, p < .05).
