2.4. Measures of life stress and residual depression

To assess any residual depressive symptomatology and ongoing stress appraisal, participants were administered the BDI-II again at the EEG session, along with the PSS (Cohen et al., 1983). The PSS is a 14-item measure of the degree to which life situations during the past month are perceived as uncontrollable (e.g., “In the last month, how often have you been upset because of something that happened unexpectedly?”). Responses range from 0 (never) to 4 (very often) and higher scores indicate greater perceived life stress.
