Approche psychologique de la qualité de vie de patients atteints de métastases cérébrales : temps, émotion et cognition.

Abstract : Little is known about the psychological determinants of quality of life in brain metastases patients treated with neurosurgical techniques, in particular the contribution of cognitive and emotional functioning. Authors encourage the consideration of temporality in order to better understand the concept of quality of life. Zimbardo and his collaborators developed a psychological time theory that links quality of life and depression, called the "time perspective". The thesis aims to confirm the predictive role of cognitive functioning in the quality of life of patients treated surgically for metastatic cerebral tumors and to better understand the relationships between time perspective, depression and quality of life. A first study compared the sociocognitive profile in inter-subjects (patients versus controls) and in intra-subjects (before neurosurgical treatment versus after), and explored determinants of quality of life (ie, cognitive functioning, depressive symptomatology and time perspective). The main results are that patients have a global cognitive dysfunction that negatively impairs their functional autonomy and that a depressive symptomatology, even minimal, is an important predictor of their overall quality of life. Patients are more oriented towards the "present-fatalistic " than the controls, and the "past" dimensions of their time perspective are related to their quality of life, notably through their influence on the emotional state. A second study examined the relationship between the "past-negative" dimension of the time perspective in particular, depression and quality of life in a group of patients. The results suggest that the depressive symptomatology of patients mediate the effects of the "past negative" dimension on their quality of life. A third study explored, through a case study, the dynamics of the time perspective profile, depressive symptomatology, "uncertainty towards the future" and quality of life during medical follow-up. The main result of this study is that the dynamics of the two "present" dimensions evolve jointly with the future uncertainty. The thesis encourages the implementation of interventional studies to evaluate the effectiveness of psychological interventions centered on the time perspective in brain metastases patients.
