Enhancing readiness-to-change substance abuse in persons with schizophrenia. A four-session motivation-based intervention.

The authors wrote a four-session class for adults who have both schizophrenia and drug or alcohol problems.

Each class mixes two ideas: the Transtheoretical "stages of change" model and harm-reduction tips.

The paper only describes the lessons. It gives no data on whether people actually cut their use.

There are no numbers, graphs, or test results. The paper is simply a lesson plan.

We do not know if the module helps clients move toward sobriety.

Dallery et al. (2021) extends this idea into the real world. They swapped the in-person talks for a smartphone app that pays smokers for clean breath tests. Their tech version hit 89 % abstinence, showing motivation plus money works.

Hatton et al. (2005) used a similar short-group format. Five sessions of role-play cut unsafe sex among HIV-positive adults who also used substances. The pattern says brief groups can change risky behavior when you add skills practice.

Sauer-Zavala et al. (2019) reminds us that fixed order may not fit everyone. They re-ordered CBT modules to match client strengths and saw faster early gains. You could borrow that idea and let the motivation lesson come later if the client is not yet ready.

You now have a ready-made four-lesson script for dual-diagnosis clients, but you will need to add measurement. Track stage of change with a quick ruler before and after the block. If you want stronger impact, pair the lessons with a reward system like Dallery’s app or add role-play skills as C et al. did. Finally, stay flexible: if a client already scores high on readiness, skip ahead to coping skills instead of sticking to the fixed order.
