Digital Therapeutics for Social Cognitive Function in Schizophrenia Spectrum Disorder

Condition(s) studied

Investigational drug(s) / intervention(s)

Digital therapeutic (AffectUs): A smartphone-based digital therapeutic application (AffectUs) that provides structured social cognition training focused on emotion processing and social cue perception. Participants use the application five times per week for approximately 10-15 minutes per session over a 10-week period (total 50 sessions). The program is self-guided and delivered through a smartphone application.

Psychoeducational materials: Structured psychoeducational materials providing information about schizophrenia, medication adherence, stress management, and daily self-management. Participants receive one psychoeducational module per week over a 10-week period. The content is informational and does not include social cognition training components.

Study summary

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.

Eligibility

Primary outcome measure(s)

• Change in Emotion Recognition Performance — Baseline and Week 10 (end of treatment)
  hange from baseline to Week 10 in performance on the Korean Facial Emotion Identification Test (K-FEIT) and Korean Facial Emotion Differentiation Test (K-FEDT). Performance is measured as the proportion of correct responses across all items, ranging from 0 to 1. Higher scores indicate greater accuracy and better emotion recognition performance.
• Change in Social Cue Perception Performance — Baseline and Week 10 (end of treatment)
  Change from baseline to Week 10 in performance on a video-based social cue perception task assessing the ability to interpret social situations and contextual social cues. The total score ranges from 0 to 40, with higher scores indicating better social cue perception performance.
