In a 6-month follow-up of 817 UHR patients, Nelson et al. found that the probability of transition differed significantly across the three UHR intake groups, rising in the order Trait-only < Attenuated Psychotic Symptoms (APS) < Brief Limited Intermittent Psychotic Symptoms (BLIPS) (p = 0.024). Thus, distinct UHR criteria confer different levels of risk for progression to psychosis [Nelson, 2011, PMID: 21074975].
