To determine whether computerized stimulus delivery and an adaptive mean span scoring metric improve the precision, reliability, and validity of digit span assessments.
Conducted two experiments administering randomized auditory digits with adaptive list-length adjustment based on participant performance.
Developed a novel mean span metric and compared its variance, reliability, and construct validity against traditional digit span scoring methods across forward and backward span conditions.
The mean span metric produced lower variance, superior test-retest reliability, and stronger correlations with other neuropsychological test measures than traditional digit span metrics.
Adaptive scoring increased the sensitivity of forward versus backward span comparisons and enabled normative performance benchmarking with subdigit precision across age and education levels.
