Supplementary Material for a Pilot RCT on Rumination-Focused CBT for Early Psychosis

A figshare-hosted document provides supplementary material for a pilot randomized clinical trial evaluating group rumination-focused cognitive behavioral therapy (RFCBT) for negative symptoms in early psychosis. The trial included 58 young adults with schizophrenia spectrum disorders, assessing feasibility and outcomes using scales like the Brief Negative Symptom Scale (BNSS) and Perseverative Thinking Questionnaire (PTQ). The author is listed as 'figshare admin karger', and the material was last updated on April 30, 2026.

Use Cases

• Analyzing clinical trial feasibility metrics based on the reported 82.14% session completion rate.
• Comparing treatment effect sizes between groups based on reported between-group differences (Δ) and Cohen's d values for scales like BNSS, PTQ, and RRS.
• Studying the relationship between repetitive negative thinking and negative symptoms in psychosis based on the trial's conceptual framework and measured outcomes.

Strengths

• Provides specific numerical results from a clinical trial, including between-group differences (e.g., BNSS Δ −5.90) and effect sizes (e.g., d=0.72).
• Includes a clear methodological description of a randomized trial with 58 participants analyzed intention-to-treat.
• Released under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (77.5 KB), indicating limited scope, likely containing only supplementary textual material rather than raw trial data.
