Introduction: Experiencing a first episode of psychosis (FEP) at young age plays an important role in one’s future life, considering its peculiarities. Since a growing emphasis on relationship between childhood adversities (CA) and increasing risk of psychosis is given, we aimed to explore associations between different types of CA and specific psychotic symptoms in FEP patients.

Method: Case histories of 91 FEP patients (ICD-10 F20-29, F30-33) aged 10-17 years, hospitalized for the first time during the years 2009-2015 were surveyed retrospectively. Data about psychotic experiences (Hallucinations, Delusions, Paranoia, Grandiosity and Negative Symptoms), mood symptoms and CA (bullying, sexual, physical and emotional abuse), also other psychosocial risk factors were collected by analyzing findings of the clinical examination and observations, psychological testing results. Correlations were assessed using phi coefficient.

Results: Comorbid psychiatric disorders showed association with sexual abuse (ϕ=0,25; p=0,017). Bullying (ϕ=0,355; p=0,025), physical (ϕ=0,382; p=0,016) and emotional (ϕ=0,339; p=0,032) abuse among girl showed association with paranoia while bullying among boys were associated with Negative Symptoms (ϕ=0,28; p=0,046). Sexual abuse among those who do not consume alcohol were associated with Grandiosity (ϕ=0,303; p=0,018). No differences between family composition, learning abilities, extracurricular activities etc. have been found (p>0,05).

Conclusions: Our findings supplement the evidence of the link between childhood adversities and psychosis while showing specific relations between different childhood adversities and psychotic symptoms. However, any firm conclusions cannot be made considering small size of the sample. Further prospective studies are required to prove specific relations.
