Diagnostic Discrimination of BOKE STARS, a Bimodal Continuous Performance Test, for Attention-Deficit/Hyperactivity...

Area of Science:

• Neurodevelopmental disorders
• Pediatric psychiatry
• Diagnostic tools

Background:

• Attention-deficit/hyperactivity disorder (ADHD) affects 6.3% of Chinese children, with low diagnosis rates due to limited culturally adapted tools.
• Existing continuous performance tests lack unimodal validity for ADHD diagnosis.

Purpose of the Study:

• To evaluate the diagnostic discrimination of BOKE STARS (Sustained Task and Attention Response Screening), a culturally adapted bimodal continuous performance test.
• To distinguish children with ADHD from typically developing children in a Chinese clinical setting.

Main Methods:

• A prospective, case-control study involved 100 children (50 with ADHD, 50 controls) aged 6-12 years.
• BOKE STARS assessment on a tablet and parent-completed SNAP-IV rating scales were used.
• Receiver operating characteristic (ROC) curve analysis assessed diagnostic discrimination.

Main Results:

• Children with ADHD performed significantly worse on BOKE STARS indices compared to controls.
• The total score (AUC 0.962) and reaction time variability (RTV) (AUC 0.919) showed the strongest diagnostic discrimination.
• Modest correlations were found between BOKE STARS indices and SNAP-IV symptom severity.

Conclusions:

• BOKE STARS demonstrates promising preliminary diagnostic discrimination for ADHD in Chinese children.
• Further external validation in diverse populations is needed before widespread clinical use.
• BOKE STARS may serve as an adjunctive tool alongside clinical interviews and rating scales.
