The purpose of this paper is to evaluate the use of node-link mapping (NLM) on the effectiveness of a structured treatment for dual diagnosis for men living in a low-secure environment.
In total, 15 participants were recruited and randomly allocated to one of two conditions. The control group, treatment as usual (TAU) or the treatment group, TAU with NLM. Outcome measures used were: a qualitative evaluation form, The Alcohol and Illegal Drugs Decisional Balance Scale and the Brief Situational Confidence Questionnaire.
Results indicate no statistically significant difference for either group on the pre- and post-treatment outcome measures used. Qualitative data indicated that those using NLM reported the intervention as useful and instructive more often.
The results gained were only a snapshot of the intervention straight after treatment and did not take into account any long-term benefits of therapy such as substance use relapse rates. The outcome measures used may not have been properly understood by all respondents, or reflect practical change. The NLM tool may not have been used as confidently as TAU. The TAU condition needs to be reviewed to improve effectiveness, and NLM to be included to improve the accessibility. A study comparing other outcome tools needs to be completed. Training for staff using NLM may require coaching.
This paper has a high/low originality. It highlights a number of advantages to NLM when comparing this to TAU.
