56-LB: The Mediating Role of Shared Responsibility in the Relationship of Trait Mindfulness and Diabetes-Related Outcomes

In youth with T1D, mindfulness and parental involvement (i.e., shared responsibility) of diabetes self-management (DSM) behaviors are associated with positive diabetes-related outcomes. This study explored the mediating role of shared responsibility in the relationship of mindfulness with DSM and A1c. A cross-sectional study was conducted among 129 adolescents aged 12-18 years with T1D at a tertiary medical center. Adolescents completed a survey on mindfulness (Child Acceptance & Mindfulness Measure), shared responsibility (Diabetes Family Responsibility Questionnaire-Short) and DSM (Self-care Inventory). A1c was obtained from medical records. The PROCESS SPSS macro by Hayes (v3.5) was used to assess mediation. Unstandardized and standardized path coefficients (β), SE, p-value, and 10,000 bias-corrected bootstraps 95% CI reported. Results: Mindfulness had positive significant association with shared responsibility (a-path=0.974, SE=.045, β=.189, R2=.036, p=.032). Shared responsibility had significant association with DSM (b-path=0.055, SE=.017, β=.275, p=.0015). The direct (c’) and total (c) relationships between mindfulness and DSM were significant (c’=0.198, SE=.087, β=.193, p=.024; c=.251, SE=.088, β=.245, R2=.06, p=.005). The relationship between mindfulness and DSM was partially mediated by shared responsibility (ab=0.053, SE=0.031 bias-corrected bootstrapped 95% CI = [0.0059, 0.0119]). For the second mediational model, neither mindfulness nor shared responsibility was associated with A1c (p>.05). Mindfulness and shared responsibility had positive association with DSM but not A1c. Shared responsibility partially mediated the relationship between mindfulness and DSM, whereby youth with higher levels of trait mindfulness had greater shared responsibility and better DSM. Temporal inferences should be interpreted with caution. Interventions targeting both mindfulness and shared responsibility should be explored. Disclosure H. Abujaradeh: None. P. Viswanathan: None. S.
