|Abstract:||Occupational recovery (i.e., return to work or to school) is a common objective among people with recent-onset psychosis. Many factors may influence occupational recovery process, such as cognitive deficits, which are core symptoms in psychotic disorders. However, the role of cognition among other key predictors of occupational recovery in recent-onset psychosis remains to be documented. In addition, usual treatments in psychotic disorders, such as pharmacological treatments, have limited impact on cognitive deficits. Cognitive remediation can reduce cognitive deficits in psychotic disorders, but few studies have evaluated its effect on occupational recovery and have attempted to personalize the intervention to enhance treatment response in recent-onset psychosis. Therefore, the general objective of this thesis was to evaluate the role of cognition on occupational recovery. To reach this goal, two studies were conducted among people with recent-onset psychosis. The first, a longitudinal study, aimed to evaluate the role played by cognition among other key predictors of occupational recovery and the second, a multiple cases study, aimed to evaluate the effect of personalized cognitive remediation on occupational recovery. In general, the longitudinal study showed that working memory and length of time absent from employment or school explained 48.1% of the variance of occupational recovery. The unique significant contribution of working memory on occupational recovery underlined that considering cognitive functioning is relevant to interventions targeting return to work or to school. The second study including three cases showed that two of them improved their occupational status after the personalized cognitive remediation therapy, as well as cognitive, psychological and/or clinical factors relevant to occupational recovery. The personalization of the cognitive remediation therapy according to individual (e.g., pre-existing cognitive deficits) and contextual (e.g., combined interventions) characteristics appeared to have enhanced treatment response. According to results of both studies, cognitive remediation could be provided as a catalyst of occupational recovery in supported employment and education programs. Indeed, cognitive remediation may improve many factors relevant to occupational recovery, such as those determined in study 1 (i.e., working memory and length of time absent from employment/school). The distinct pathways leading to return to work or to school suggested that mechanisms through which cognitive remediation influence occupational recovery may be heterogeneous, underlying the relevance of personalizing interventions.|
