A meta‐analysis of neurofeedback for treating substance use disorders

Abstract

AbstractA meta‐analysis was conducted to assess the efficacy of neurofeedback (NFB) in the treatment of individuals with substance use disorder (SUD) in between‐group studies. This study reports findings from the first exhaustive search of the literature on the topic and included articles selected from a total of 58 databases/repositories. Studies were evaluated using Hedge's g as the effect size measure and were assessed for risk of bias using funnel plot, Fail‐Safe N, and Trim and Fill analysis. Ten studies, containing 30 effect sizes were evaluated to determine the overall efficacy of NFB for decreasing symptoms of SUD (N = 397), yielding a mean effect size of g = –1.49 (CI 95 = –1.95, –1.03; PI 95 = –4.37 to 1.39). This meta‐analysis provides strong evidence for the efficacy of NFB in treating SUD while also highlighting the value of wholistic client care in SUD treatment.
