Abstract:
Psychologists in inpatient psychiatric settings sometimes are asked to assess whether patients improve or decline in intellectual functioning. The impetus for this referral question may be a perceived change in psychiatric status, an acute neuropathological event, e.g., a head injury, or a suspicion of an early dementing process. For this study, data from 100 inpatients who completed the WAIS–R on two separate admissions were used to calculate confidence bands for measurement error surrounding test-retest difference scores. The analysis indicated that, if the retest interval is three months or less, significant practice effects must be factored into the interpretation of difference scores. A table for the interpretation of difference scores at different testing intervals is provided.
