Adults have similar literacy habits as children, such as reading to gain knowledge or for enjoyment. However, when workplace literacy skills are considered, these practices are not always book related and usually involve informal communication such as collaboration between workers. This study used data from the 2012 Program for the International Assessment of Adult Competencies to examine adults' literacy skills. A total of 39 adult literacy skills were examined to explore patterns among them, effectively reducing them to nine interpretable factors. Each factor focused on an area of literacy skills, such as work-related reading, educating others, and writing. The nine factors that consisted of 37 variables accounted for 59.2% of the total variance in the adults' literacy habits.
