Abstract Background: Treatment-resistant depression (TRD) represents a significant clinical challenge, associated with severe disability and high societal costs. Cognitive Behavioral Therapy (CBT) is a first-line psychotherapy, but its specific efficacy in TRD populations warrants detailed synthesis.
Objective: This review aims to systematically evaluate the evidence for CBT as a monotherapy and augmentation strategy for TRD, examining its mechanisms, efficacy across delivery formats, predictors of response, and implementation challenges.
Methods: A narrative review was conducted of randomized controlled trials, meta-analyses, and key observational studies published between 2000 and 2025. Literature was identified from PubMed, PsycINFO, and Cochrane Library databases and analyzed thematically.
Results: Robust evidence supports CBT as an effective intervention for TRD. As an augmentation to pharmacotherapy, CBT significantly improves symptom reduction and remission rates compared to medication management alone. Specialized protocols, such as the Cognitive Behavioral Analysis System of Psychotherapy (CBASP), show particular promise for chronic presentations. Proposed mechanisms include the modification of persistent negative cognitive schemas and increased behavioral activation. Modest evidence suggests factors like cognitive flexibility and specific neuroimaging profiles may predict favorable outcomes.
Conclusion: CBT is a validated and essential component of the TRD treatment arsenal. It addresses residual cognitive-behavioral symptoms often untouched by pharmacotherapy and provides durable, relapse-protective benefits. Future research must prioritize standardized TRD definitions, biomarker-driven personalization, and the optimization of scalable delivery models to improve accessibility and integration into stepped-care algorithms.

Abstract Backgrounds: Anxiety disorders represent a major global public health challenge due to their high prevalence, significant disability burden, and substantial economic costs. Cognitive Behavioral Therapy (CBT) has emerged as the most extensively researched and empirically supported psychological intervention for these conditions. This comprehensive review synthesizes contemporary evidence on the efficacy, core therapeutic components, evolving applications, and implementation challenges of CBT across the anxiety disorder spectrum.
Methods: We conducted a narrative review of the scientific literature from January 2000 to March 2025, focusing on high-quality meta-analyses, systematic reviews, randomized controlled trials (RCTs), and key theoretical papers. Database searches included PubMed, PsycINFO, and Cochrane Library using controlled vocabulary and keywords related to CBT, specific anxiety disorders, therapeutic mechanisms, and treatment outcomes.
Results: Substantial evidence confirms CBT's superior efficacy compared to waitlist controls and psychological placebos, with large effect sizes (Hedges g typically >0.80) and sustained benefits. Disorder-specific protocols demonstrate strong efficacy, while transdiagnostic approaches offer comparable outcomes with improved efficiency for comorbid presentations. Core techniques—particularly exposure based on inhibitory learning principles—show robust effects, though dropout rates (15-25%) and partial response remain significant challenges. Technology-enhanced delivery methods (internet-based CBT, virtual reality) demonstrate effectiveness with improved accessibility.
Conclusion: While CBT maintains its status as first-line psychotherapy for anxiety disorders, important gaps exist between efficacy in controlled trials and effectiveness in routine care. Future directions should prioritize personalized treatment algorithms, mechanism-targeted interventions, cultural adaptations, and implementation strategies that improve real-world delivery. Integration with biological interventions and process-based approaches represent promising avenues for enhancing outcomes for non-responders.

Abstract Objective

This review aims to consolidate current knowledge on the effectiveness of CBT and related therapeutic approaches for addressing anxiety and depression in people with advanced cancer.

Methods

A narrative review method was adopted to integrate findings from various sources, including systematic reviews, randomized trials, pilot studies, and research protocols, all examining CBT, mindfulness-based practices, and other forms of psychotherapy within advanced cancer populations.

Results

Findings suggest that CBT and similar interventions can provide meaningful relief from anxiety and depressive symptoms, though the degree of benefit varies. Mindfulness-based approaches appear particularly helpful in promoting a sense of existential well-being and supporting caregivers. Some structured CBT programs have not demonstrated consistent benefits across all patient groups, with improvements often observed in specific subpopulations. Overall, broader psychotherapeutic approaches indicate the potential for moderate symptom reduction, but evidence remains limited. Newer approaches, such as behavioural activation, are currently under study and may offer alternative options.

Conclusion

Psychological therapies, including CBT, show important but variable effects in managing anxiety and depression in individuals with advanced cancer. Interventions that are tailored to individual patient characteristics, levels of distress, and situational needs may be more effective. Continued research through well-designed, focused trials is essential to better understand how these therapies can be optimized in this population.
