Transtheoretical Model of Change
The Transtheoretical Model of Change (TTM), also known as the Stages of
Change Model, is a behavioural change theory that explains how individuals
modify behaviours over time through a series of identifiable stages. Developed
by psychologists James Prochaska and Carlo DiClemente during the early 1980s,
the model proposes that change is a gradual process rather than a single event.
Individuals may move forwards and backwards through different stages before
achieving lasting behavioural change. Within social work, the Transtheoretical
Model helps practitioners assess a person's readiness for change and tailor
interventions to match their current stage, promoting person-centred,
motivational and strengths-based practice (Prochaska & DiClemente, 1983).
The Transtheoretical Model was originally developed through research into
smoking cessation after Prochaska and DiClemente observed that successful
behaviour change rarely occurred immediately. They found that individuals
progressed through predictable stages of readiness before making sustainable
changes. The model has since been widely applied to substance misuse, mental
health, physical health, domestic abuse, offending behaviour, safeguarding,
weight management and many other areas of behavioural change. Its flexibility
has made it one of the most influential behaviour change models used across
healthcare, psychology and social work (Prochaska & Velicer, 1997).
A central feature of the model is its six stages of change.
The first stage is Precontemplation, where the individual does not recognise that
a problem exists or has no intention of changing their behaviour. They may deny
concerns, minimise risks or feel resistant to intervention. At this stage,
practitioners focus on raising awareness, building trust and providing information
without applying excessive pressure.
The second stage is Contemplation, where the individual begins recognising that
change may be necessary but remains uncertain or ambivalent. They often
weigh the advantages and disadvantages of changing while struggling with
conflicting emotions. Practitioners support individuals by exploring motivation,
identifying barriers and encouraging reflection.
The third stage is Preparation, during which the individual intends to take action
and begins planning for change. This may involve setting goals, seeking support,
gathering information or developing practical strategies. Social workers
