Understanding Teach-Back and Teach-To-Goal Strategies Embedded in Support Calls for a Health Literacy-Sensitive Childhood Obesity Treatment Trial

Abstract

BACKGROUND: Low caregiver health literacy (HL) is related to increased obesity risk for their children. Teach-Back and Teach-to-Goal (TB/TTG) are strategies that may improve comprehension of key concepts for people who have low HL but have yet to be examined in the context of childhood obesity treatment. OBJECTIVE: This study evaluated TB/TTG strategies integrated within support calls delivered to caregivers as part of a 3-month childhood obesity intervention. METHODS: Ninety-four caregivers (60% Black, 42% high school education or less, 53% with income ≤$29,999, and 34% low HL) with overweight/obese children age 8 to 12 years enrolled in a childhood obesity intervention. Caregiver HL was assessed at baseline using the Newest Vital Sign and caregivers were dichotomized to low and adequate HL groups for analyses. Caregivers received 6 bi-weekly support calls that alternated with in-person, family sessions. Call completion rates, comprehension of key content (correct responses on TB/TTG questions), and satisfaction with support calls were evaluated. Qualitative information on call satisfaction was gathered at the 3-month time point. KEY RESULTS: Average completion rate across all calls was 62% with a mean call time of 26 minutes (no significant difference between HL groups). Caregivers had an average score of 0.90 out of 1 when evaluating overall call comprehension by scoring TB/TTG performance. Content comprehension in calls 1, 3, and 4 was significantly higher among caregivers with adequate HL relative to low HL (p
