Classification Accuracy of Sequentially Administered WAIS-IV Short Forms

Abstract Objective The Boston Naming Test (BNT) has several short forms do not include the noose item. These short forms have been mainly examined in dementia populations. This study compared BNT short forms with standard administration (BNT-S) in physical medicine and rehabilitation patients. Method Participants (N = 480) completed the BNT in an outpatient evaluation. The sample was 34% female and 91% white with average age and education of 46 (SD = 15) and 14 (SD = 3) years, respectively. Diagnoses included traumatic brain injury (62%), mixed neurologic conditions (21%), and stroke (17%). Five 15-item short forms were calculated: Consortium to Establish a Registry for Alzheimer’s Disease (CERAD-15); Lansing; and Mack 1, 2, and 4 (Mack-15.1, −15.2). Three 30-item short forms were calculated: Mack A, Saxon A, and BNT odd items. Short forms and BNT-S were compared with Spearman correlations. Cronbach’s alpha was calculated for all forms. Impaired BNT scores were determined using norm-referenced scores (T < 36). Area under the curve (AUC) values were compared across short forms with impaired BNT as criterion. Results BNT-S showed strong correlations with 30-item (rho = .92–.93) and 15-item short forms (rho = .80–.87) except for CERAD-15 (rho = .69). Internal consistency was acceptable for 15-item (alpha = .72–.80) and 30-item short forms (alpha = .85–.86). BNT was impaired in 17% of participants. AUC values were not significantly different in 15-item (AUC = .83–.89) and 30-item (AUC = .91–.92) groups. CERAD-15 (.83), Mack-15.1 (.87), and Mack-15.2 (.87) AUC values were significantly lower than 30-item short form AUC values. Conclusion BNT 30-item and 15-item short forms showed outstanding and excellent classification accuracy, respectively. BNT short forms warrant further study in rehabilitation settings.

Future Work

The Worry Domains Questionnaire was proposed as a measure of both pathological and nonpathological worry, and assesses the frequency of worrying about five different domains: relationships, lack of confidence, aimless future, work, and financial. The present study analyzed the factor structure of the long and short forms of the WDQ (WDQ and WDQ-SF, respectively) through confirmatory factor analysis in a sample of 262 students (M age = 21.8; SD = 2.6; 86.3% females). While the goodness-of-fit indices did not provide support for the WDQ, good fit indices were found for the WDQ-SF. Furthermore, no source of misspecification was identified, thus, supporting the factorial validity of the WDQ-SF scale. Significant positive correlations between the WDQ-SF and its subscales with worry (PSWQ), anxiety (STAI-T), and depression (BDI) were found. The internal consistency was good for the total scale and for the subscales. This work provides support for the use of the WDQ-SF, and potential uses for research and clinical purposes are discussed.
