Behavioral activation (BA) works by interrupting the depression cycle of withdrawal and reduced reinforcement (Martell, Dimidjian, & Herman-Dunn, 2010). Most BA worksheets are session-by-session: the client schedules activities for the coming week. This 30-day version takes a habit-formation approach, designed for clients in the maintenance phase or working independently. It pairs three specific daily activities — one for movement, one for connection, one for mastery — and tracks them across 30 days, building automaticity through repetition rather than relying on motivation. Research on habit formation (Lally et al., 2010) suggests behaviors become automatic over an average of 66 days, but meaningful momentum typically appears within 21-30 days of consistent practice.

Choose three small activities you will commit to daily for 30 days: one MOVEMENT (walk, stretch, dance), one CONNECTION (text a friend, call family, sit with a pet), one MASTERY (one chore, one creative act, one task you have been avoiding). Pick activities small enough to do on your worst day. Each day, note whether you did each one (Y/N), how it felt (1-5), and one observation. Do not skip days even when you feel fine — the point is the rhythm.
