Objective: The pressure is on to reduce the cost of clinical supplies in neuropsychology practice settings with decreasing medical insurance reimbursement rates and increasing need to demonstrate financial viability. The open source, no cost, Hopkins Adult Reading Test generates estimates of both Verbal (HART-VIQ) and Full Scale (HART-FSIQ) intelligence quotients. The Wide Range Achievement Test – Fourth Edition (WRAT) Word Reading test offers a standard score that similarly is used as an estimation of premorbid intellectual abilities but currently costs $2.14 per form (plus tax and shipping). We wished to determine if a score similar to the actual WRAT Word Reading score could be acquired without the cost of over $2 per patient. Method: We used stepwise multiple regression analyses to predict WRAT Word Reading score with archival data of 441 outpatients who had been seen either in a community hospital or a small private practice setting. Predictors of AGE (M = 69.2), EDUCATION (M = 12.9), and HART scores were used with the criterion being WRAT (M = 96.7). Results: The HART-VIQ model (1.2*HART-VIQ + .08*AGE - 35.7) offered a significant equation predicting WRAT performance (R2 = 0.69), as did the HART-FSIQ model (1.2*HART-FSIQ + 0.10*AGE - 41.0; R2 = 0.67). Neither model included EDUCATION in the prediction models, suggesting that HART scores already take into account education levels when predicting WRAT scores. Conclusion: These equations seem reasonable to use in a setting when low cost options are required to estimate premorbid functioning.
