Efficacy of Personalizing Cognitive Remediation for Schizophrenia by Targeting Impairments in Early Auditory Processing

Brief summary (registry, in English)

The primary aim of this study is to provide confirmation that Cognitive Remediation (CR) for schizophrenia, when personalized based on pre-treatment assessment of early auditory processing ability, facilitates improved cognitive and functional outcomes. Additional aims of this study address the mechanisms of treatment effect. The study uses a repeated-measures randomized trial design. Enrollment will be by invitation, open to individuals receiving services at select community behavioral health facilities where CR is offered. Clients who are eligible for the service, who agree to participate in research and who meet inclusion/exclusion criteria will be assessed on outcome measures and categorized via performance on the Tone Matching (TM) test, as EAP impaired (EAP-) or EAP intact (EAP+). Subsequently, EAP- and EAP+ subgroups will be randomized to either (1) Brain Basics (BB; n = 100), an EAP-enhanced CR approach or (2) Brain Training (BT; n = 100), a routine CR approach. Participants will be invited to participate in a second pre-treatment assessment to measure electrophysiologic responses to auditory stimuli. All participants will be scheduled to repeat outcome measure assessments after treatment and after a follow-up period. The EAP- group receiving BB will be invited to repeat electrophysiological paradigms post-treatment to investigate mechanisms of change related to the CR intervention. Verbal learning will be the primary outcome with functional capacity the secondary outcome. EEG is exploratory and will examine neurophysiologic markers of need for and response to EAP training.
