Digital Therapeutics for Social Cognitive Function in Schizophrenia Spectrum Disorder

19 août 2026 mis à jour par: Jung-Seok Choi, Samsung Medical Center

A Prospective, Randomized Parallel, Single Institution, Researcher-led Clinical Trial on the Effect of Improving Social Cognitive Function by Using Digital Therapy Devices in Patients With Schizophrenia Spectrum Disorder

The purpose of this study is to evaluate the safety and preliminary effectiveness of a smartphone-based digital therapeutic application (AffectUs) for improving social cognition, particularly emotion processing and social cue perception, in individuals with schizophrenia spectrum disorders.

In this randomized controlled trial, participants will be assigned either to use AffectUs for 10 weeks in addition to treatment as usual or to receive psychoeducational materials and treatment as usual. Participants will complete assessments at baseline, week 5, week 10, and week 15 to evaluate social cognition, clinical outcomes, and safety.

Description détaillée

Social cognition refers to the mental processes involved in perceiving, interpreting, and reasoning about others' emotions, intentions, and behaviors. Patients with schizophrenia spectrum disorders consistently exhibit deficits in social cognition, which are associated with impaired social functioning and psychosocial outcomes and remain an important treatment target despite pharmacological management.

Although psychosocial interventions targeting social cognition have demonstrated beneficial effects, their implementation is often limited by the need for prolonged, therapist-led, in-person treatment. Recent studies suggest that digital interventions may improve accessibility while producing meaningful improvements in core social cognitive domains, particularly emotion processing and social cue perception.

Based on this evidence, AffectUs was developed as a smartphone-based digital therapeutic application that provides brief, repeated, remote training in emotion processing and social cue perception for individuals with schizophrenia spectrum disorders. This exploratory study evaluates the safety and preliminary effectiveness of AffectUs and aims to provide foundational evidence for future confirmatory clinical trials of digital therapeutics for schizophrenia spectrum disorders.
