The Auditory Processing Abilities Test (APAT) is a nationally standardized, norm-referenced auditory processing battery for use with children ages 5;0 through 12;11. Use the APAT to: identify children who are at risk or who may be experiencing Auditory Processing Disorder (APD); determine a child's specific strengths and weaknesses among a number of auditory processing skills; document a child's improvement in auditory processing skill abilities as a result of therapeutic interventions. The authors developed the APAT using a model based on a hierarchy of auditory processing skills that are basic to listening and processing spoken language. These skills range from sensation to memory to cohesion.
Primarily designed for use by speech-language pathologists, other professionals such as learning disabilities specialists, psychologists, and resource specialists will find the APAT easy to administer and score.
The APAT is comprised of 10 subtests that quantify a child's performance in various areas of auditory processing:
The APAT provides composite index scores, individual subtest scores, a Global Index reflecting overall auditory processing efficiency, a Linguistic Processing Index, and an Auditory Memory Index. Optional analyses allow further examination of Linguistic Processing tasks (yielding indices for discrimination, sequencing, and cohesion) and Memory tasks (yielding indices for immediate recall, delayed recall, sequential recall, and cued recall).
Reliability and Validity
Internal consistency measures are relatively high: across all ages, Cronbach's Coefficient Alpha for subtest items ranges from 0.70 to 0.89; Spearman-Brown Correlations range from 0.75 to 0.93. Subtest SEMs are relatively low, ranging from 0.79 to 1.51 across all ages. Criterion-related validity coefficients are moderately high; the correlation between subtest scores from APAT Phonemic Awareness and LAC-II is 0.54, while the correlation between percentile ranking of APAT Total and LAC Total is 0.53. Because the LAC provides only composite scores that assess a number of skills and APAT individual subtest scores reflect discrete skills, correlations are lower than if one were comparing two discrete sets of similar skills.
Administration and Scoring
Administered individually, the APAT can be completed and scored in less than 45 minutes. It yields scaled scores and percentile ranks for subtests and standard scores and percentile ranks for the composites. Age equivalents are available for all areas assessed.
