Researchers in the 1970s created a “model of change” to help people stop harmful behaviors. Today, the model is useful for preventing habits from worsening.

What stage of change is a person in if they start to think seriously about planning to make a long term change in the near future?

When the transtheoretical model (TTM) was developed in the 1970s and early 1980s by researchers James O. Prochaska and Carlo DiClemente, it was revolutionary in its explanation of how behavioral change can take root and how it’s maintained over time.

TTM became popular in substance use disorder treatment.

But research from the early 2000s questioned whether TTM was helpful in this way, because of the difficulty in pinpointing a person’s readiness to change.

Another criticism was that TTM excluded people who succeeded in quitting an addiction cold turkey. Yet another criticism noted that TTM may oversimplify substance use disorder and recovery.

Recent research indicates that TTM may be best suited for people who need to take preventive action to better their health, rather than rewiring entrenched behaviors.

Here’s how.

The TTM gauges a person’s readiness to change and the likelihood they will continue that change forward.

There are six stages of change in this framework. It begins with no desire to change and ends with maintaining new behavior and the completion of treatment.

There’s evidence that TTM works by changing behaviors preemptively in people at risk of developing chronic diseases and before negative thought patterns can contribute to the development of mental health issues.

The stages of change may be most effective by defining what each level means to you, how your experience fits into a stage, and whether you can preemptively adopt a behavior change.

I need to change my behavior. How can TTM help?

To make a long-term behavioral change using TTM, first identify your present stage. A therapist or psychologist may be best able to help identify which stage you’re in:

  1. precontemplation
  2. contemplation
  3. preparation
  4. action
  5. maintenance
  6. termination

Once you’ve done that, you can speak with a professional who specializes in the type of change you want to make.

You can learn about behavior-changing programs and which one will assist you in your particular path, and you might be motivated to commit to following it.

Like G.I. Joe says, “Knowing is half the battle.” TTM helps you know where you are, and what stages you can look forward to next.
