What this Trial Is About

Being active is one way to reach better blood sugar control and heart health in type 2 diabetes. The investigators developed a strategy to help people with type 2 diabetes walk more. They track their steps with a step counter and set targets with their doctor through a kind of 'step prescription.' While this strategy helps people increase their physical activity, it can be useful to have support besides the clinic visits. Their partner might be a good person to help. Partners often have similar activity levels. Partners of people with type 2 diabetes are also more likely to develop type 2 diabetes. There are good reasons to work together! However, not all partners communicate in a way that helps them work together effectively. The investigators are going to give a step counter and step prescriptions to a large group of people with type 2 diabetes. The partners will also receive counters and step prescriptions. Half of the couples will be randomized (assigned to a group based on something equivalent to a coin toss) to participate in online or in-person sessions with a counselor. They will work together to figure out how to communicate more kindly and effectively. The investigators will see if the people with these sessions wind up having higher steps and better sugar control than the people who do not. To figure out in which types of couples the strategy works, The investigators will also divide the couples into groups based on the type of marriage that they have (figured out through a questionnaire) and body size. The investigators will see if the counseling strategy helps in both 'high' and 'low' quality relationships and if couples where both partners have extra weight respond differently to the strategy than other couples. During the trial, if The investigators see that the strategy is not working well in one particular group of people, The investigators may recruit fewer in this group and more in the others. The investigators will do this in consultation with specialized statisticians who will look at the data at specific points in time. This is a way of making sure that the investigators are testing the right strategy in the right group, increasing the 'efficiency' and relevance of the study.
