Interrogating Consequential Validity Evidence in NAPLEX Studies Involving the Use of Demographic Variables

Objective: to review the purpose, methods, and discussion of student demographics related to North American Pharmacist Licensure Examination (NAPLEX) performance; demographic characteristics, significant findings, and related text were extracted from each reviewed article as evidence of consequential validity. Findings: Nine articles met the inclusion criteria. Prior degree attainment (n = 8, 88.9%), age (n = 6, 66.7%), race/ethnicity (n = 6, 66.7%), and sex (n = 5, 55.6%) were the most common demographic variables included. One study found that prior degree attainment was negatively related to NAPLEX performance and no studies using this variable discussed their findings. Three studies found significant relationships between age and NAPLEX performance, attributing differences to older students for "unique psychosocial challenges and competing responsibilities" "greater maturity" and being more "professional." Measures of race/ethnicity differed in every study, with 3 reporting significant findings and 2 discussing their findings. Studies referenced literature suggesting that "minority groups" tended to score lower on standardized examinations while others referenced literature that suggests "standardized testing may not be predictive of the performance of minority students." Sex was not related to NAPLEX performance nor was it discussed in any studies. Summary: Consequential validity evidence is a critical yet underreported aspect of NAPLEX evaluation in pharmacy education. How demographic variables are selected, utilized, and discussed warrants further exploration and consideration by educators, scholars, and practitioners as these decisions can have important sociocultural and political implications.
