Narrative Identity and Its Relationship to Subjective Multidimensional Well-being in First Episode Psychosis

Narrative Identity and Its Relationship to Subjective Multidimensional Well-being in First Episode Psychosis

The transition between adolescence and adulthood (generally defined as ages 18 to 25) is a key developmental window for narrative identity and psychotic disorders. Narrative identity is positively associated with mental health. This study will focus on the acquisition of narrative identity in First Episode Psychosis (FEP) and its impact on multidimensional subjective well-being.

The study authors hypothesize that levels of the various components of narrative identity would be lower in the FEP group than in the "chronic" and control groups, and in the "chronic" group versus control group. Given the paucity contradictory nature of the published literature, no hypotheses have been formulated regarding these correlations and predictions. Instead, this study will remain an exploratory analysis in the different samples.
