Abstract: First episode psychosis (FEP) is the first manifestation of some of the mean mental disorders; Mainly schizophrenia, and Bipolar disorder. Though longitudinal studies of FEP have focused mainly at symptom remission, currently there is a growing interest in functional outcome Likewise' the relation between symptom remission and functional recovery in matter of current debate. Despite the fact of its pragmatic nature, functional assessment is not standardised, and different studies use different measures. On the other hand, longitudinal studies involve a handful of different methodologies, mainly derived from clustering methods, or an extension of mixed model theory. This study explores different longitudinal latent growth models for the modelling of both functional and symptomatic outcomes for a sample of 335 FEP cases followed for a period of two years. The functional outcomes were measured by the Functioning Assessment Short Test (FAST) and symptoms outcome as scored by the positive, negative and general PANSS scale. The results showed heterogeneous trajectories for both functional and symptom outcomes. There was an appreciable association between poor symptoms remission and impoverished functional recovery, specially within negative symptoms. Furthermore the study depicts a strong relation between some socio demographic characteristics, such as the educational levels, and some beeline variables such as the premorbid adjustment scale, IQ and days of untreated psychosis to both poor functional and negative symptoms outcomes. Moreover, more severe symptoms onset, especially in regards to negative and depressive symptoms, was related to both poor functional and symptomatic outcomes. Baseline functional assessment per the WHODAS, geopte and GAF scale also proves to be strongly related to both functional and symptomatic outcomes.
