Quick answer
CBT (Cognitive Behavioral Therapy) is the leading therapy for both anxiety and depression, and can be tailored to treat them together — combining thought-challenging, behavioral activation for depression, and exposure for anxiety. Other approaches like ACT and behavioral activation also help both. CBT has the strongest evidence.
CBT: effective for both
CBT is the therapy with the strongest evidence for both anxiety and depression, which makes it ideal when the two co-occur. It works by helping you understand and change the patterns maintaining both conditions — the negative, distorted thinking (anxious 'what ifs' and depressive hopelessness) and the unhelpful behaviors (anxious avoidance and depressive withdrawal). A skilled CBT therapist can address both together within one coherent treatment, targeting the anxious and depressive elements as they arise. This flexibility and dual effectiveness is why CBT is typically the first-line therapy for co-occurring anxiety and depression.
How it addresses both
CBT for combined anxiety and depression weaves together techniques for each. For the depression side: behavioral activation — gradually re-engaging with rewarding, meaningful activities to counter the withdrawal and loss of pleasure — plus challenging hopeless, self-critical thinking. For the anxiety side: exposure (gradually facing feared situations rather than avoiding them) and challenging catastrophic, threat-focused thinking. Both share work on unhelpful thinking patterns and on re-engaging with life. Because the two conditions feed each other, addressing them together — rather than one at a time — often works better, and CBT is well-suited to this integrated approach.
Other helpful approaches
While CBT leads, other evidence-based therapies also help both anxiety and depression. Behavioral activation (a core component of CBT, sometimes used on its own) is effective for both. Acceptance and Commitment Therapy (ACT) — which focuses on accepting difficult feelings while acting on your values — helps both conditions. Mindfulness-based approaches can support both, particularly for preventing relapse. Interpersonal therapy helps depression and can ease associated anxiety. When choosing, look for a therapist experienced with both anxiety and depression who uses evidence-based methods (ask about CBT specifically). A note of care: if you have thoughts of harming yourself, please reach out for support right away. Therapy genuinely helps co-occurring anxiety and depression — finding the right therapist is a valuable step toward recovery.
