Internet-delivered CBT is feasible and acceptable for treating childhood anxiety at home via videoconferencing, with a pilot study showing high treatment retention and satisfaction. Telehealth interventions, particularly telehealth-to-home, are effective for depression and anxiety, improving quality of life, with recommendations for more research on video platforms, provider adoption, and legislative reforms. Cognitive Behavioral Therapy (CBT) is effective for childhood anxiety disorders through homework that generalizes skills, although motivation issues can impact efficacy. For treating anxiety in older adults or rural populations, CBT can provide significant symptom relief when delivered to the home, supplementing existing protocols. Home-based exercise significantly reduces anxiety and depression symptoms, improving functional capacity and quality of life, especially among chronic illness patients, elderly populations, and lung cancer survivors. Regular exercise can be an effective part of care for reducing anxiety, with high-intensity exercises having a more pronounced effect. Mindfulness-based therapies and complementary self-help treatments like massage, music therapy, and relaxation show potential, though further rigorous testing is required. Internet-based cognitive-behavioral therapy and bibliotherapy offer effective alternatives to face-to-face therapies, aiding those unable or unwilling to access conventional treatment options. Self-help interventions for anxiety disorders show promise, with studies indicating Internet-delivered CBT and bibliotherapy can provide significant symptom relief and long-term improvement, offering viable alternatives suitable for stepped care models.
