Objective
To assess differences, by health literacy status and behavioral condition, in participants’ abilities to accurately self-monitor behaviors and recall key behavioral messages using data from a teach-back call.
Design
Cross-sectional.
Setting
Rural, southwestern Virginia.
Participants
Adults (n=301). Majority (81.1%) were female, 31.9% had ≤high school education, 66.1% earned <$25,000 per year, and 32.9% were low health literate.
Intervention
First class session of two community-based behavioral interventions: SIPsmartER (reduce sugar sweetened beverage intake) or MoveMore (increase physical activity).
Main Outcome Measures
Reported accuracy of behavioral diary completion, proportion of behavioral messages recalled during the first round of teach-back, and rounds of teach-back.
Analysis
Descriptive statistics and GLM.
Results
Low health literate participants were significantly less accurate in diary completion (P<.001), recalled fewer behavioral messages correctly (P<.001), and needed more rounds of teach-back (P<.001) than high health literate participants. Compared to SIPsmartER participants, MoveMore participants more accurately completed diaries (P=.001), but recalled a lower proportion of behavioral messages correctly (P<.001) and required more rounds of teach-back
Conclusions and Implications
Health literacy status and behavioral target impact ability to self-monitor and recall key concepts. Researchers should consider using teach-back early in the intervention to assess and reinforce participants’ ability to self-monitor.
