A Randomized Study of Values Affirmation to Promote Interest in Diabetes Prevention Among Women With a History of Gestational Diabetes.

objectiveThe objective of this study was to test whether 2 interventions promote interest in diabetes prevention among women with a history of gestational diabetes mellitus, who face high lifetime risk for diabetes. RESEARCH DESIGN AND

methodsWe designed an email outreach message promoting an existing preventive lifestyle program. The message incorporated values affirmation, a theory-based intervention that can improve openness to health information but typically relies on a writing exercise less practical in health care settings. In a 3-arm randomized study, 237 women with elevated body mass index and a history of gestational diabetes mellitus were randomized to read an outreach message containing either no affirmation (control) or 1 of 2 affirmations, streamlined to remove the typical writing exercise: either a values affirmation prompting reflection on any personal value, or a parenting affirmation prompting reflection on caregiving-related values. Outcomes included demonstrating interest in the lifestyle program (seeking information about it or intending to join) and seeking publicly-available health information about diabetes prevention.

resultsCompared with control, participants randomized to the values affirmation more frequently demonstrated interest in the lifestyle program (59.0% vs. 74.4%; adjusted relative risk: 1.31; 95% confidence interval: 1.04-1.66) and sought information about diabetes prevention (59.0% vs. 73.4%; adjusted relative risk: 1.22; 95% confidence interval: 0.97-1.54). The parenting affirmation yielded no significant differences in either outcome.

conclusionsA streamlined values affirmation, designed for feasibility in a health care setting, can promote interest in diabetes prevention among women at high risk. Research is needed to evaluate its effects on diabetes prevention program enrollment and clinical outcomes.
