Group CBT Effects on Hostile Attribution Bias in Adolescents with ASD Traits

Hidehiro Umehara's study data includes pre- and post-intervention psychological indices for 15 adolescents and young adults with autism spectrum disorder traits who completed an 8-session group cognitive behavioral therapy program. The dataset, last updated in April 2026, contains change rates for hostile attribution bias, social functioning, and subjective quality of life. It is a 33.5 KB DOCX file shared under a CC-BY-4.0 license.

Use Cases

• Analyze the correlation between changes in hostile attribution bias and subjective quality of life based on the reported Spearman correlation.
• Evaluate the effect size of group CBT on social communication and interaction based on the Social Responsiveness Scale (SRS-2) scores.
• Study the discordant pattern between cognitive bias reduction and well-being improvement mentioned in the exploratory individual-level analysis.

Strengths

• Includes effect size calculations (e.g., ES = 0.698 for hostile attribution bias) and p-values for pre-post changes.
• Data is linked to a registered clinical trial (UMIN000030140), providing traceability.
• Psychological indices are measured with standardized tools like the Ambiguous Intentions Hostility Questionnaire and SRS-2.

Limitations

• The dataset is very small at 33.5 KB, indicating limited scope and sample size (n=15 completers).
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for statistical modeling.
