Aim: Following the introduction of an access and waiting time standard for Early Intervention in Psychosis (EIP) services, the identification and treatment of people experiencing an At-Risk Mental State (ARMS) for psychosis has become a national priority. However, there is a dearth of literature concerning what is offered to and accepted by ARMS service users within routine services. Methods: This descriptive evaluation reports upon the assessment and treatment of people with an at-risk mental state identified during the first year of a routine service operating in line with the EIP standard. The paper details referral sources, referral to treatment times, socio-demographic characteristics, ARMS subgroups and the interventions accepted by these service users. Results: A total of 138 ARMS cases were identified over the evaluation period, with 73% (n=101) aged between 18-34 years and 86% (n=118) meeting attenuated psychotic symptoms criteria. The majority (64%) of service users engaged in multiple interventions; 54% (n=75) accepted psychoeducation and coping skills enhancement work, 42% (n=58) participated in a sleep programme, 33% (n=45) undertook coping with voices and visions work and 28% (n=39) engaged in individual psychological therapy. Conclusion: The findings indicate that the majority of ARMS service users presenting to the EIP service were aged 18-34 and experienced attenuated psychotic symptoms. A range of NICE and CBT informed interventions as well as individual psychological therapies appear to be acceptable to ARMS service users and many engaged in multiple interventions offered.
