Comparative effects of non-pharmacological interventions on anxiety, depression and quality of life in individuals with substance use disorders: A systematic review and network meta-analysis.

Researchers analyzed 117 studies involving over 11,000 people with substance use disorders to compare different non-drug treatments for anxiety, depression, and quality of life. The study, which examined data from 25 countries, looked at how well various interventions worked, including acupuncture, exercise, cognitive behavioral therapy, meditation and mind-body practices, brain stimulation techniques, and relapse prevention programs.

The findings showed that several approaches helped reduce anxiety and depression symptoms in the short term. Acupuncture was among the treatments that showed benefits for both anxiety and depression when compared to control groups receiving usual care or minimal intervention. Other effective options included neuromodulation (brain stimulation), mind-body therapies like meditation and yoga, conventional exercise, and cognitive behavioral therapy. For quality of life improvements, the results were less clear immediately after treatment ended, though some approaches like mind-body therapy showed promise.

When researchers ranked all the treatments, neuromodulation scored highest for anxiety and quality of life, while mind-body therapy ranked best for depression. Acupuncture performed well across multiple outcomes. The study also found that treatment effectiveness varied depending on how long the intervention lasted and the country's development level.

For patients with substance use disorders struggling with anxiety or depression, this research suggests acupuncture may be a helpful complement to standard addiction treatment. However, the study emphasized that short-term effects were measured, and individual responses vary. When considering acupuncture, patients should discuss their specific needs with their treatment team and seek a licensed acupuncturist experienced in addiction recovery support.

This network meta-analysis evaluated non-pharmacological interventions for mental health outcomes in substance use disorder populations across 117 RCTs (n=11,177) from 25 countries. Using random-effects frequentist network meta-analysis examining earliest post-intervention assessments, researchers compared multiple intervention modalities including acupuncture, neuromodulation, mind-body therapies, cognitive behavioral therapy, conventional exercise, and relapse prevention against pooled controls.

Results demonstrated that acupuncture showed favorable estimates for reducing both anxiety and depression symptoms compared to control conditions. Neuromodulation ranked highest via SUCRA analysis for anxiety and quality of life outcomes, while mind-body therapy ranked first for depression. Quality of life improvements at immediate post-intervention timepoints showed imprecise estimates across interventions. Subgroup analyses revealed effect modification by country development level and intervention duration.

Clinical implications: Acupuncture demonstrates evidence as an adjunctive treatment for comorbid anxiety and depression in SUD patients, particularly in integrated care models. Practitioners should consider intervention duration, patient preferences, and local feasibility when implementing non-pharmacological approaches. The evidence supports short-term symptom reduction, though longer-term outcomes require further investigation. Head-to-head comparative data remains limited.
