Despite the large scientific debate concerning potentially stigmatizing effects of informing an individual about being in an at-risk mental state (ARMS) for psychosis, studies investigating this topic are rare and quantitative assessment of this kind of stigmatization does not exist so far.

This study presents first results regarding potentially helpful or stigmatizing effects of being informed about an ARMS assessed with a newly developed quantitative self-rating (FePsy-Stigma questionnaire).

Forty ARMS patients participating in the prospective Basel Early Detection of Psychosis (FePsy) study as well as patients clinically assessed in the early detection service of the Psychiatric Services of Solothurn, completed the FePsy-Stigma questionnaire during their follow-up assessments at least six months after they had been informed about their increased risk of developing psychosis. The questionnaire was constructed based on a previous qualitative study and on adapted versions of formerly used instruments for assessing stigma in mental health (Internalized Stigma of Mental Illness Scale, Personal Beliefs and Experiences Questionnaire).

Stigmatization appeared to be low overall except for social withdrawal due to suspected stigma. Stigma resistance, stereotype awareness and expected discrimination scored considerably higher than actually experienced discrimination, alienation and stereotype endorsement.

The results suggest that early detection services help individuals cope with symptoms and build certain resilience toward potential stigmatization, rather than enhancing or causing the latter. In line with previous studies, our results indicate that there is a considerable difference between expected and actually experienced discrimination as well as between stereotype awareness and stereotype endorsement.
