Introduction

Clinical neuropsychologists employ various domains to assess cognitive functions, essential for diagnosing impairments accurately. Ensuring the precision and reliability of cognitive measurement tools is crucial (Rae-Grant & Parsons, 2014). Psychometric properties play a vital role in assessing the suitability of these tools for their intended purposes. Validity, ensuring the tests measure what they aim to, and reliability, guaranteeing consistent and replicable results, are pivotal considerations (Cohen et al., 2022).

Clinical neuropsychologists utilize several assessment batteries to measure cognition, often supplementing them with additional tests to address patient concerns. Commonly employed assessments include the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Neuropsychological Assessment Battery (NAB), and the Halstead-Reitan Neuropsychological Battery (HRNB). These batteries cover various cognitive domains and aid in determining the cognitive status of patients (Rae-Grant & Parsons, 2014).

Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)

The RBANS comprises 12 subtests assessing immediate and delayed memory, visuospatial abilities, language, and attention. It is suitable for individuals aged 12-89 years (Randolph, 2012). Conversely, the NAB consists of 36 tests across six modules, evaluating attention, language, spatial abilities, memory, and executive function in adults aged 18-97 years. Notably, the NAB offers flexibility in administration and includes a screening module to determine further testing needs (Stern & White, 2003).

The HRNB focuses on physical brain function and the impact of brain damage or injury, with ten tests assessing motor function, language, auditory processing, attention, executive function, and visuospatial abilities. Initially developed for individuals aged 14-50 years, revisions have expanded its applicability to individuals up to 85 years old (Rae-Grant & Parsons, 2014).

Technical Review Article Summaries for the RBANS

McKay et al. (2007) investigated the validity of the RBANS in patients with moderate to severe traumatic brain injuries (TBI). They found the battery produced index scores comparable to specific domain tests, indicating its effectiveness as a comprehensive tool. The study, including 57 adults with TBIs, demonstrated strong reliability for the RBANS total scale score (.83), albeit with weaker reliability for language and attention subtests. However, each subtest showed validity comparable to other neuropsychological tests measuring similar domains, affirming the RBANS’ convergent validity.

Gontkovsky et al. (2004) evaluated the psychometrics and reliability of the RBANS in a healthy geriatric sample. With 631 participants aged 64-94, they found high internal consistency (Cronbach’s alpha = .86) and significant correlations between individual test scores and domain index scores. These findings support the RBANS’ reliability and convergent validity in detecting cognitive impairments in older adults.

Technical Review Article Summaries for the NAB

Donders and Levitt (2012) examined the criterion validity of the NAB in individuals with traumatic brain injuries (TBI). Their study, involving 54 TBI patients, demonstrated significantly worse performance compared to healthy counterparts. The NAB showed sensitivity to TBI, validating its effectiveness in assessing cognitive impairments in this population.
