Verbal Short-Form FSIQ Estimations for Possible Use With Individuals With Motor and Visual Impairment or in Virtual Environments.

OBJECTIVE:Abbreviated and virtual neuropsychological assessment practices are growing in popularity and viable alternatives to traditional testing methods are needed, especially in the face of global health concerns. This study generated and examined short form (SF) full-scale IQ (FSIQ) estimations, which lend themselves to virtual test administration. METHODS:Archival data were procured from 318 concurrent cognitive evaluations at a university clinic. Twenty-six unique SF combinations, including dyads, triads, tetrads, and pentads, were created from Wechsler Adult Intelligence Scale, 4th edition (WAIS-IV) subtests within verbal comprehension and working memory indices due to these tests' ability to be administered without visual stimuli or psychomotor involvement. RESULTS:Stepwise regression analyses revealed 9 SF combinations (i.e., 1 pentad, 3 tetrads, 2 triads, and 3 dyads) that significantly accounted for unique variance in FSIQ scores and provided good accuracy estimating FSIQ. CONCLUSION:Results suggest the potential viability of verbal WAIS-IV SF FSIQ estimations for clinical use when assessing patients with motor or visual impairments, as well as performing tele-neuropsychological services.
