Trans-theoretical Model for Change

From Prochaska et al., 1994, 2002, 2014) — the Transtheoretical Model proposes that behavior change occurs in five sequential stages: (1) precontemplation (not planning to change within the next 6 months), (2) contemplation (ambivalent or thinking about change), (3) preparation (taking steps towards changing), (4) action (attempting the change), and (5) maintenance (having been able to sustain behavior change for more than 6 months and working to prevent relapse). Furthermore, 10 “processes of change” are considered important in facilitating movement between different stages, and 2 additional variables influence that process: decisional balance (evaluating the pros and cons of changing) and self-efficacy. (see L. Laranjo, in Participatory Health Through Social Media, 2016).
