<p> This study is an <i>ex post facto</i> correlational study that analyzed the mediated relationship between <i>everyday adult literacy practices (directions or instructions; letters, memos, or mail; newspapers or magazines; professional journals or publications; books, manuals or reference materials; financial statements; diagrams, maps, or schematics)</i> and <i> literacy scores,</i> using <i>vocabulary scores</i> as the mediator while controlling for <i>educational attainment, current educational practices, age,</i> and <i>number of books at home.</i> This study used the Program of International Assessment of Adult Competency (PIAAC) 2012/2014 public use household dataset which includes data from over 8,000 participants. This dataset contains information about participants’ background, daily lives, and reading practices as well as literacy, numeracy, and informational technology skills. Analyses were completed using the IDB analyzer to complete regression analyses on the final sample which included 1,599 participants who had taken both the literacy and print vocabulary assessment. The Sobel process was used to determine mediation. According to the Sobel test, the <i>vocabulary score</i> mediated the relationship between <i> reading letters, memos, or mail</i> (b = 4.18, SE = 0.23, <i>p</i> < .001) and <i>newspapers or magazines</i> (b = 2.55, SE = 0.29, <i> p</i> < .05) and the <i>combined plausible literacy score.</i> This showed that a portion of the ability to predict adult literacy scores from the frequency of reading letters, memos, or mail and newspapers or magazines could be due to vocabulary proficiency.</p><p>
