Figure 1. MCI Status, marital status, and lagged loneliness interact to predict intrusive thoughts. Note. T: momentary assessment; T − 1: previous momentary assessment (i.e., 3–4 hours before T); significant slopes are bolded (neither dashed lines are significant); N’s for each group: MCI and married (29), MCI and not married (72), No MCI and married (77), No MCI and not married (139).
