Risk of suicidality across depressive symptom profiles at different levels of optimism

Note: Results of the logistic regression analysis, converted into probabilities, were used to evaluate the buffering effect of optimism in the association between depressive symptom profile and risk of suicidality. Figure 3a shows that risk of suicidality of the Moderate to Severe depression profile decreased as the level of optimism increased, whereas the suicidality risk of the Mild and Low depression profiles did not change much as the level of optimism increased. Figure 3b shows that differences in the suicidality risk between the Moderate to Severe and Low depression profiles decreased (i.e., a stronger buffering effect) as the level of optimism increased, whereas risk differences between the Mild and Low depression profiles did not change much as the level of optimism increased.
