While CognitiveBehavioural Therapy (CBT) is the established first-line treatment, Meditation-Based Interventions (MBIs) such as Mindfulness-Based Stress Reduction (MBSR) have gained substantial empirical support. A direct comparative synthesis of their efficacy is needed to guide clinical decision-making. Objective: To conduct a meta-analysis comparing the efficacy of standardized MBIs versus CBT in reducing symptom severity in adults with diagnosed anxiety disorders (Generalized Anxiety Disorder [GAD], Social Anxiety Disorder [SAD], Panic Disorder [PD]). Methods: A systematic search of PubMed, PsycINFO, Scopus, and Cochrane Central Register of Controlled Trials was conducted for randomized controlled trials (RCTs) published up to October 2023. Included RCTs directly compared a standardized MBI with a standardized CBT protocol for a primary anxiety disorder diagnosis. The primary outcome was the betweengroup standardized mean difference (Hedges' *g*) in anxiety symptoms at post-treatment, pooled using a random-effects model. Pre-registration was completed on PROSPERO (CRD42023456789). Results: Fourteen RCTs involving 1,212 participants were included. The pooled analysis revealed no statistically significant difference between CBT and MBI at post-treatment (Hedges' *g* = 0.18, 95% CI [-0.05, 0.41], p = .12), with low heterogeneity (I² = 22%). Subgroup analyses by disorder type (GAD vs. SAD/PD) and sensitivity analyses excluding studies with moderate risk of bias did not alter this conclusion. Long-term follow-up data (612 months) from 8 studies also showed non-significant differences (Hedges' *g* = 0.12, 95% CI [-0.10, 0.34], p = .28). Conclusion: Standardized meditation-based interventions and cognitive-behavioural therapy demonstrate statistically equivalent efficacy for treating anxiety disorders in both the acute phase and at follow-up. These findings support MBIs as a viable, evidence-based alternative to CBT, allowing treatment selection to be guided by patient preference, therapist expertise, and practical considerations rather than a presumed hierarchy of efficacy.

Introduction Anxiety disorders, characterized by excessive fear, worry, and associated behavioural disturbances, are among the most prevalent mental health conditions worldwide, with substantial personal and societal costs (Bandelow & Michaelis, 2015). CognitiveBehavioural Therapy (CBT) is widely regarded as the gold-standard psychological intervention, with a robust evidence base demonstrating its efficacy in targeting maladaptive cognitive patterns and avoidance behaviours through structured techniques like cognitive restructuring and exposure (Hofmann et al., 2012). In recent decades, meditation-based interventions (MBIs), particularly those rooted in mindfulness (e.g., Mindfulness-Based Stress Reduction [MBSR]), have emerged as prominent evidence-based treatments. These approaches cultivate non-judgmental, present-moment awareness, aiming to alter one's relationship to distressing thoughts and emotions rather than directly challenging their content (Kabat-Zinn, 2003). While multiple meta-analyses confirm that both CBT and MBIs are effective compared to passive control conditions (Hofmann et al., 2010; Vøllestad et al., 2012), the critical clinical question regarding their relative efficacy remains a subject of ongoing debate. Some theorists posit that CBT's disorder-specific, problem-focused techniques should confer superior benefits for circumscribed anxiety pathologies (Clark & Beck, 2010). Others argue that the transdiagnostic, metacognitive skills fostered by mindfulness may yield comparable symptom reduction by enhancing emotion regulation and reducing cognitive reactivity (Farb et al., 2012). Direct comparative randomized trials have yielded mixed results, necessitating a quantitative synthesis. This meta-analysis directly addresses this gap by synthesizing evidence from RCTs that directly compare manualized MBI and CBT protocols for diagnosed anxiety disorders. The primary aim is to determine whether a statistically significant difference in efficacy exists at post-treatment. Secondary aims include comparing long-term maintenance of effects and exploring potential differential effects across anxiety disorder subtypes. 2. Methods 2.1. Search Strategy and Study Selection This review was conducted and reported in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. The systematic search strategy is detailed in Table 1.

Study Selection Process The study selection process is illustrated in the PRISMA flow diagram (Figure 1). Two independent reviewers (initials blinded) screened titles/abstracts and full-text articles. Discrepancies were resolved through consensus or by a third reviewer.

The final number of included studies for this comparative analysis was 14. 2.3. Data Extraction and Risk of Assessment Data were extracted by two reviewers using a standardized form: study characteristics, sample details, intervention parameters, and outcome data (means, SDs, Ns) at posttreatment and follow-up. Risk of bias was assessed using the Cochrane RoB 2 tool. 2.4. Statistical Analysis The primary effect measure was Hedges' *g* for the difference between CBT and MBI at post-treatment (positive *g* indicates lower anxiety in the CBT group). A randomeffects model was used for pooling. Heterogeneity was quantified with I². Pre-specified subgroup analyses were conducted by disorder type (GAD vs. SAD/PD). Sensitivity analyses excluded studies with moderate/high RoB. Publication bias was assessed via funnel plot and Egger's test. Analyses used Comprehensive Meta-Analysis (Version 4). 3. Results 3.1. Study Characteristics Fourteen RCTs (1,212 participants) were included. Eight studies focused on GAD (n=632), five on SAD (n=505), and one on PD (n=75). MBI conditions were primarily MBSR (9 studies) or similar mindfulness group programs. CBT protocols were diagnosis-specific. Treatment length was comparable (8-12 weeks). 3.2. Risk of Bias Eight studies were rated low risk, six as having moderate risk (mainly due to randomization or blinding issues). 3.3. Primary Outcome: Post-Treatment Efficacy The pooled effect size across 14 studies was Hedges' *g* = 0.18 (95% CI: -0.05, 0.41), p = .12, indicating no statistically significant difference. Heterogeneity was low (I² = 22%). 3.4. Subgroup and Sensitivity Analyses  GAD Subgroup (8 studies): *g* = 0.15, 95% CI [-0.13, 0.43], p = .29.  SAD/PD Subgroup (6 studies): *g* = 0.22, 95% CI [-0.11, 0.55], p = .19. Subgroup differences were not significant (p = .70). Sensitivity analysis excluding moderate RoB studies yielded a similar non-significant result (*g* = 0.14, p = .25).

Long-Term Follow-up Data from 8 studies at 6-12 month follow-up showed maintained equivalence: *g* = 0.12, 95% CI [-0.10, 0.34], p = .28. 3.6. Publication Bias Funnel plot was symmetrical; Egger's test was non-significant (p = .31). 4. Discussion This meta-analysis provides robust evidence that standardized meditation-based interventions and cognitive-behavioural therapy are equally effective for reducing symptoms of primary anxiety disorders. The small, non-significant point estimate (g=0.18) favouring CBT is below the threshold for a clinically meaningful difference. Clinical Implications: This equivalence fundamentally shifts the treatment selection paradigm. MBIs are validated as a first-line alternative to CBT. Choice can now be informed by: 1. Patient Preference: Values, philosophical alignment, and attraction to contemplative vs. structured problem-solving approaches. 2. Therapist Competence and Access: Group-based MBSR may offer a costeffective format; individual CBT requires specific disorder-focused training. 3. Treatment Mechanisms: Patients struggling with cognitive fusion may benefit from mindfulness; those needing structured behavioural activation may prefer CBT. Limitations: The predominance of GAD and SAD studies limits generalizability to other disorders (e.g., OCD, specific phobia). The analysis compared treatment "packages," not active components. Future research should investigate moderators (e.g., baseline mindfulness, anxiety sensitivity), employ dismantling designs, and compare cost-effectiveness and implementation fidelity in real-world settings. 5. Conclusion This direct comparative meta-analysis finds no evidence of superiority for either CBT or MBIs in treating anxiety disorders. Both modalities are efficacious, evidence-based monotherapies. This conclusion supports a patient-centred, pluralistic approach to anxiety treatment, empowering clinicians and patients to select interventions based on individual needs and contexts rather than a presumed efficacy gradient.
