Systematic review of cognitive and behavioral strategies used in effective harm reduction interventions for people who use cocaine

OBJECTIVE

The aim of this systematic review is to identify cognitive and behavioral strategies that have been used in effective harm reduction interventions for people who use cocaine.

METHOD

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed, and the search was performed on February 26, 2023 across databases including PsycInfo, PubMed, Scopus, and Web of Science. Studies were included if they (1) report the use of one cognitive or behavioral strategy, (2) have harm reduction as the objective, (3) involve participants who used cocaine as at least one of their substances, (4) be published within the last 10 years, and (5) have a randomized controlled trial design. The Cochrane RoB 2.0 Tool was used to assess risk of bias. The cognitive and behavioral strategies were extracted and organized based on their frequency of use in the studies and their corresponding outcomes.

RESULTS

The final synthesis included k = 10 studies with N = 3,567 participants. Psychoeducation strategies, influence on social norms, personalized feedback, increased self-efficacy and motivational interviewing were the most frequently used promising strategies across studies.

CONCLUSIONS

This review underscores the significance of incorporating cognitive and behavioral strategies within harm reduction interventions, as they represent a promising domain that could enhance the effectiveness of addressing cocaine use.

Psychoeducational and Cognitive Behavioral Treatment Programs: Implementation and Evaluation From 1995 to 2015 in Kraepelin's Former Hospital

OBJECTIVE

Programs that view individuals as capable of taking an active role in managing their illness have gained importance in Europe and the United States. This article describes the implementation and evaluation of group psychoeducational and cognitive behavioral treatment programs at the Department of Psychiatry and Psychotherapy, Ludwig Maximilian University, Munich, Germany, over the past 20 years.

METHODS

Implementing psychoeducational programs was the first step to establish cognitive behavioral psychotherapy and dispel the myth of schizophrenia for patients. Programs are also provided for patients with mood disorders, substance use disorders, or both. These groups include topics such as psychoeducation about the illness, establishing rewarding activities, stress management, cognitive therapy, and relapse prevention.

RESULTS

More than 1000 patients with schizophrenia or mood disorders (380 schizophrenia, 563 major depression, and 110 bipolar) have participated in illness management groups to learn about their illness and its treatment, and to learn skills to manage their illness. Patients have expressed satisfaction with the programs, and research has supported their effectiveness.

CONCLUSIONS

Individuals with severe disorders can benefit from psychoeducational and cognitive treatment programs if the programs are adapted to the level of neuropsychological functioning and compensate for cognitive deficits and emotional overload. These findings suggest that providing information about the illness and coping skills for patients and relatives are important for treatment outcome.
