“…Participants responded to six Likert-type items completing the stem "My partner … " (1 = strongly disagree, 7= strongly agree), such as "interferes with the things I need to do each day" and "makes it harder for me to schedule my activities." Although the means of the relational uncertainty variables were relatively low, they are consistent with previous research on relational uncertainty (e.g., Boucher, 2015;Knobloch, 2007Knobloch, , 2008Steuber & Solomon, 2012). Furthermore, given that our focus in the present analysis was on the change in these variables rather than on the absolute levels of the variables, the variance that is relevant for the present analysis is the variance in the change scores, not the variance in the levels of the relational uncertainty variables.…”
