Relationships between the National Adult Reading Test and memory.

Abstract

The aims of this study were to investigate the relationships between performance on the National Adult Reading Test (NART) and retrospective, concurrent, and prospective memory functioning, as well as between the NART and change in memory functioning over time. NART administered in 2005 was used as a predictor for memory functioning in 2001, 2005, and 2008, and change in memory functioning from 2001 to 2008. Outcome measures were Logical Memory II, Letter-Number Sequencing, and Spatial Span from the Wechsler Memory Scale. Participants were 319 healthy women aged 40-79 years at baseline (2001). Significant correlations were found between the number of errors on the NART and memory measures in 2001, 2005, and 2008; Logical Memory II (r = -.41, -.38, -.39, respectively), Letter-Number Sequencing (r = -.38, -.35, -.36, respectively) and Spatial Span (r = -.23, -.22, -.19, respectively; all p values < .001). NART significantly added to predictions of all three measures of memory, after controlling for age, level of education and socioeconomic status. NART also significantly added to predictions of change in Logical Memory II and Letter-Number Sequencing over a 7-year period. The results indicate that the NART is correlated with episodic and working memory, and that the NART added to predictions of change in verbal episodic and working memory. Although the relationships are only moderate at best, the NART may be used in conjunction with demographic information and clinical reasoning to estimate premorbid memory functioning.
