The Mediation Effects of Self-Efficacy on the Relationship Between Diabetes-Related Content Exposure and Self-Management Among Older Diabetics: A Cross-Sectional Study
Abstract
AIMS
To map the diabetes-related content exposure of older adults with Type 2 diabetes mellitus, and explore the association between the exposure and self-management and the mediation effects of self-efficacy.
DESIGN
Cross-sectional study.
METHODS
This study was conducted among 257 eligible older adults with Type 2 diabetes mellitus from five communities in China. Diabetes self-management and self-efficacy were measured with standardised assessment tools. The variable of diabetes-related content exposure was generated by the collection of all content exposure and the transformation of Q-methodology. Descriptive statistics and the relative mediation effect model were used to do the analyses.
RESULTS
Among the participants, 61.1% had hyperbeneficial content exposure, 13.6% had hypobeneficial content exposure, 24.9% had irrelevant content exposure, and 0.4% had harmful content exposure. Compared with those with irrelevant content exposure, older adults with hyperbeneficial content exposure exhibited higher self-management scores (β = 0.448, 95% CI = 0.174-0.721); in the mediation model, the relative direct effect of hyperbeneficial content exposure on self-management remained significant (β = 0.377, 95% CI = 0.104-0.650), and self-efficacy significantly mediated this relationship (β = 0.071, 95% CI = 0.011-0.154). The relative mediation effect accounted for 15.8% of the relative total effect. Conversely, no significant effect of hypobeneficial content exposure on…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause. Reported size: 257 participants or records.
