项目摘要
Project Summary
Prevention of schizophrenia has primarily focused on adolescents and young adults who are considered to be
at clinical high risk (CHR) for psychosis. These youngsters display subtle clinical symptoms that are similar to
psychosis but not as intense, and therefore considered to still be amenable to early intervention. Initial
prevention efforts used anti-psychotics as the primary preventive agents but these were shown to be largely
ineffective. More recent approaches have focused on the remediation of the cognitive deficits that are readily
apparent and predictive of future illness in CHR adolescents. However, while cognitive remediation has shown
substantial promise for improving cognitive deficits and improving outcomes in patients with schizophrenia, it
has not yet been markedly successful with CHR youth. The proposed study will test an innovative internet-
based remotely-delivered Specific COgnitive REmediation plus Surround (or SCORES) intervention for CHR
adolescents ages 14-20 years old that targets early processing speed deficits as measured at the
neuropsychological level with the processing speed domain from the NIMH-Measurement and Treatment
Research to Improve Cognition in Schizophrenia (MATRICS) consensus cognitive battery. The proposed
SCORES treatment package is grounded in a theoretical framework, supported by findings from our group and
others, where processing speed deficits contribute to poor social functioning, which in turn leads to an
increased risk for psychosis. We specifically selected cognitive remediation because it directly targets a core
cognitive mechanism, processing speed, which is a rate limiting factor to higher order behaviors and clinical
outcome in CHR adolescents. To overcome past difficulties in applying a cognitive remediation treatment to
CHR teenagers, we have developed a platform to support our targeted processing speed training, which
involves reducing the heterogeneity of the CHR study population (including a reduced age range, narrowed
clinical criteria, and targeting individuals with pre-existing processing deficits). In addition, we have adding a
novel support surround component which is expected to increase enjoyment and promote retention. In the
single-arm R61 phase, a 2-year proof of concept study, 30 CHR individuals will receive SCORES for 10
weeks(4hrs per wk/40 hrs total) with a midpoint assessment at 20 hours (5 weeks) to demonstrate target
engagement and identify the optimal dose of SCORES needed to engage the target. In the R33 phase, a 3
year pilot study, we will replicate target engagement in a new and larger sample of 54 CHR individuals
randomized to SCORES (optimized dose)or to a Video GameControl condition to firmly establish the centrality
of processing speed. In addition, the R33 phase will determine if changes in target engagement are associated
with improved social functioning and decreasing attenuated positive symptoms.
项目摘要
精神分裂症的预防主要集中在青少年和年轻人身上,他们被认为是
处于精神病的临床高风险(CHR)。这些年轻人表现出类似于
精神错乱,但没有那么严重,因此被认为仍然可以接受早期干预。首字母
