Depressive symptoms influence the individual’s psychological functioning. Among the related changes, the fluctuations of cognitive and affective states constitute essential information in understanding the functioning of depressed patients. Methods taking into account the specificities of temporal processes now allow the follow-up of affects and cognitions. However, only few works investigated the depressive state and the effects of a therapeutic intervention considering its evolution over time. Relying on the Ecological Momentary Assessment (Stone & Shiffman, 2008), this research aims to complete the current knowledge of the temporal evolution of cognitive and affective dimensions in depression (study 1) and to assess the effect of a physical activity program on this evolution (study 2). Study 1 compares the temporal evolution’s features of depressed mood, anxiety, brooding and self-esteem between depressed individuals (n = 14) and control ones (n = 26). Results demonstrate a specific evolution of these psychological dimensions in depression, independently of their levels, implying that the related information remains unconsidered through the usual assessments of depression. Study 2 highlights an antidepressant effect of a threemonth physical activity program in depressed patients (n= 10) and its influence on the temporal evolution and the functioning of cognitive and affective states related to depression. This work opens new windows in analyzing temporal processes involved in the depressive symptomatology and suggests interpretative leads regarding the psychological dynamics in Major Depressive Disorder.
