Psychodynamic therapy is one of the four schools of Freud’s psychoanalytic theory. Psychodynamic therapy focuses on how unconscious processes manifest in the patient’s behaviour. The goals are awareness and understanding of the past about current behaviour. In its brief form, the approach allows the patient to examine their symptoms and unresolved conflicts and dysfunctional relationships that come from the past and that manifest themselves in the need to abuse substances. The elements that best characterize it are the formalization of an evaluation process and elaboration of a therapeutic contract on establishing a limit for therapy (which is linked to focusing the intervention on a limited focus). 
These elements could be interpreted as a slight approach to behaviour therapy 3. Expressive Supportive Psychotherapy 7 is a psychodynamic therapy approach tailored to substance abuse. It has been used in heroin-dependent patients, in methadone maintenance and in cocaine-addicted patients in which the relationship between drug use, feelings and behaviours of patients is emphasized.
Brief Family Therapy.
Substance use disorders do not occur in isolation. For many individuals, interactions with a family of origin and their current family triggered a dynamic for substance use. Interactions with family members can aggravate or perpetuate or help resolve the problem. Family therapy suggests that when the client is exposed to signs of substance abuse, he is strongly influenced by the family and the behaviours of the members of his communication. To understand these factors, the therapist considers various structural factors in the family and how they contribute to substance abuse (power hierarchy, roles, communication, etc.). The effectiveness of using this type of therapy has been proven 22. Brief family therapy is an option that can be used:
- When working on a specific problem in the family.
- When the goals are focused on a focus of current interactions.
- When the family can benefit from teaching and communication to better understand the substance use disorder.
Brief Group Therapy.
Group therapy is one of the most widely used modalities in treating drug addiction. It is appropriate because it allows patients to observe the progress of their addictive behaviour through themselves and others, and it provides the opportunity to experience personal and group success in a supportive and hopeful atmosphere. In its brief format, evaluating the patients before being included in the group and checking their expectations regarding the therapy is indicated. The duration is from 6 to 12 sessions of 1-1.5 hours, depending on the goals established in the group. One of the most important issues that group therapy offers to addicted patients is what we call group cohesion, which is the attachment that group members have to each other. (including the therapist). The interpersonal relationships that are established between the members of the group are very important in the treatment of addictions. Most patients who suffer from addiction have problems relating to each other and maintaining egalitarian relationships. The new relationships established in the protective environment of group therapy can help each patient improve their self-care and self-esteem and achieve adequate emotional.…
