The questionnaire on self-reported adherence to medications provided preliminary findings on some of the variables that are associated with or ‘predict’ non-adherence. These variables are important because they suggest ways that individuals who may have difficulties with adherence could be identified. The intent of studies finding such “predictors” is not to characterize persons who might not be prescribed medication but rather, to identify persons who may need additional assistance and to provide information that could be used to maximize the effectiveness of the assistance.

The survey identified two predictors of non-adherence. The first of these was the frequency of alcohol intake, with a higher frequency associated with skipped doses. The average number of drinks per month among those who did not report skipping medication was 9, whereas the average number of drinks per month among those who reported skipping medication was 17. The second variable significantly associated with non adherence was “working outside the home for pay’ ” Specifically, 59% of the adherent survey respondents worked outside the home, the prevalence of working outside the home was significantly higher, at 85%, among those who are non-adherent. This latter variable is consistent with the data indicating that among the reasons for missing medications is being away from home and busy with other daily activities.
