Assess each of the adults you are teaching. Many problems can be linked to poor self-control. Some problems may be underlying causes of the control issues, and some may occur as consequences. If you are, for instance, teaching a group of people who have been incarcerated, focus on breaking this pattern. Consult with others who know the adults in a professional way. For instance, some of your clients may also be attending anger-management sessions, so see if you can speak to the leader of those sessions.
Establish an open, trusting environment in the classroom. The adults have some sensitive issues to discuss, so an atmosphere of trust is essential. Teach them about child development and the development of conscience, independent thinking and problem-solving. Discuss some factors that may interrupt this development, such as a role-model leaving, or parental neglect.
Use current affairs and both real and fictitious case studies to promote role-play and discussion. Focus particularly on consequences. Some people have a real problem thinking about the consequences of behavior, or others, as often is the case with drug addicts, choose to push the consequences to the back of their mind.
Confront attitudes and behavior in a constructive and supportive way. You may find that some adults who lack self-control are firmly fixed on blaming someone else for this. Encourage the clients to take responsibility for their actions.
