AbstractBackgroundThe aim of the current study was to examine the heterogeneity of functional outcomes in first episode psychosis (FEP) patients and related clinical, neurocognitive and sociodemographic factors using a cluster analytic approach.MethodA large sample of FEP patients (N = 209) was functionally reassessed 10 years after the first contact with an early intervention service. Multiple baseline, 3-year and 10-year follow-up variables were explored.ResultsThe cluster analysis emphasized the existence of six independent clusters of functioning: one cluster was normal overall (42.16%), two clusters showed moderate interpersonal (9.63%) or instrumental (12.65%) deficits, two clusters showed more severe interpersonal (12.05%) or interpersonal and instrumental (13.85%) deficits and there was a significantly overall impaired cluster (9.63%). Cluster comparisons showed that several baseline and follow-up factors were differentially involved in functional outcomes.ConclusionsThe current study demonstrated that distinct clusters of functioning in FEP patients can be identified. The fact that a variety of profiles was observed contributes to a better understanding of the nature of the heterogeneity characterizing FEP patients and has clinical implications for developing individualized treatment plans.
