Test-retest reliability and practice effects across measures of attention in college-aged adults

Seventy-three undergraduate psychology students (86.5% female; <i>M</i> age = 19.6) completed a two-session battery approximately two weeks apart, including the Paced Auditory Serial Addition Test (PASAT), Auditory Consonant Trigrams (ACT), Digit Span (Forward, Backward, Sequencing, and Total Score), and Conners’ Continuous Performance Test-3 (CPT-3).

Reliability was excellent for PASAT (<i>r</i> = .86), ACT (<i>r</i> = .78), Digit Span Total (<i>r</i> = .82), and CPT-Commissions (<i>r</i> = .77). Reliability was good for Digit Span Forward (<i>r</i> = .72), Digit Span Backward (<i>r</i> = .71), CPT d′ (<i>r</i> = .67), CPT-Omissions (<i>r</i> = .60), CPT HRT (<i>r</i> = .72), and CPT ISI (<i>r</i> = .68). Fair reliability was observed for Digit Span Sequencing (<i>r</i> = .53), CPT-Perseverations (<i>r</i> = .46), and CPT HRT SD (<i>r</i> = .59).
