摘要

Few studies have examined effects of intrinsic motivation (IM) on adaptive behaviors among adolescents with type 1 diabetes (T1D), although greater IM has been associated with less diabetes-related family conflict (FC) and increased regimen adherence. Greater FC has also been associated with disordered eating behaviors (DEBs). We examined the moderating role of IM between FC and DEBs in a culturally diverse sample of youth with T1D. 226 adolescents (Mage = 15.03, 59.3% female, 65.8% Hispanic, 19.0% Black, MA1c = 8.19%, 74.30% eligible for subsidized health insurance) completed pre-visit screening measures assessing IM, FC, and DEBs. Gender, race, ethnicity, A1c, BMI, and insurance status were obtained from medical records and treated as covariates. Black youth had higher rates of DEBs (p < .01) and A1c levels (p < .001) than White youth. Significant correlations were observed across study variables. Accounting for covariates, IM moderated the relationship between FC and DEBs, whereby the effect of FC on DEBs emerged strongest at low IM (p < .001). As IM levels increased, the effect of FC on DEBs decreased, making the relationship between FC and DEBs non-significant. Greater IM for diabetes management attenuates the association between FC and DEBs. Promoting IM may decrease FC and DEBs in youth with T1D.
