The goal of this clinical trial to test whether a remotely delivered behavioral activation-based intervention called "teleABLE" works better than a health education intervention for (1) reducing sitting time and (2) improving health-related quality among adults who were diagnosed with stroke within the past 12 months.

Participants in this study will:

• Complete questionnaires at Weeks 1, 8, and 24
• Wear an activPAL monitor at Weeks 1, 8, and 24
• Participate in the teleABLE intervention (12 sessions) or the health education intervention (6 sessions)
• Complete an interview at Week 24
