Salivary Cortisol Levels and Depressive Symptomatology in Consumers and Nonconsumers of Self-Help Books: A Pilot Study

Figure 1

Repeated-measures of (a) diurnal cortisol and (b) reactive cortisol as a functioning of groups based on preference for problem-focused or growth-oriented self-help books. These graphs are used strictly to represent the mean (standard error bars) cortisol concentrations and to show the magnitude of the cortisol response to the TSST in each of the groups tested. As such, they have no relation to the statistical model employed that otherwise used the composite measure of area under the curve for cortisol levels (basal, reactive, and CAR).
