Introduction

Non-psychotic axis I diagnoses are highly prevalent in at-risk mental state (ARMS) and first episode psychosis (FEP) patients, the most common being affective and anxiety disorders. Few studies have examined differences between ARMS and FEP patients or gender effects regarding such diagnoses.

Objective

To examine current and lifetime comorbidities in ARMS and FEP patients. Furthermore, to examine gender differences, and differences between patients with (ARMS-T) and without later transition to psychosis (ARMS-NT).

Methods

This study was part of the Früherkennung von Psychosen (FePsy) study. Current and lifetime axis I comorbidities were assessed using the Structured Clinical Interview for DSM-IV (SCID-I).

Results

One hundred and thirty-two ARMS and 98 FEP patients were included. Current comorbidities were present in 53.1% of FEP and 64.4% of ARMS patients, the most common being affective, anxiety and substance use disorders. Current affective disorders were significantly more common in ARMS than FEP. Lifetime comorbidities were diagnosed in 58.2% of FEP and 69.7% of ARMS patients, with significantly more affective and anxiety disorders in ARMS than FEP. Male FEP patients had more current and lifetime substance use disorders (across all substances) compared to female FEP. No differences emerged between ARMS-T and ARMS-NT.

Conclusions

As expected ARMS patients have many comorbidities, while clearly diagnosed FEP have less comorbidities. There were few gender differences in axis I comorbidities. Moreover, no differences between ARMS-T and NT emerged, suggesting that axis I comorbidities do not improve prediction of transition. Nevertheless, the high comorbidity prevalence is relevant for global functioning and clinical treatment.
