Soriano, Emily C.2022-02-082022-02-082021https://udspace.udel.edu/handle/19716/30270This dissertation consists of three papers (one peer-reviewed publication, one under peer review, and one in preparation) that collectively represent important empirical and methodological contributions to the literature. A critical barrier to improving diabetes treatment by involving partners is that we currently lack an understanding of precisely how and under what conditions partners facilitate or impede diabetes management. Knowledge of when partner involvement (including what type) should be encouraged or avoided is essential to address weaknesses in prior approaches and develop more potent, targeted, and long-lasting interventions. To begin addressing these gaps, this dissertation is the first study to examine moderators of the effects of social control on continuously measured glucose in people with type 2 diabetes (PWD). Following a General Introduction (Chapter 1), two empirical papers (Chapters 2 and 3) tests moderation effects at both the between- and within-person level. A methodological paper (Chapter 4) provides a comprehensive guide on the implementation of many of the methods key to these empirical papers. Finally, a general discussion and synthesis is provided in Chapter 5.Continuous glucose monitorDiabetesGlucoseSelf-managementSocial controlSocial supportThesis1295613211https://doi.org/10.58088/dvat-f5922021-09-30en
