Gen Hosp Psychiatry 2022; 79:135-145. [PMID: 36375342 DOI: 10.1016/j.genhosppsych.2022.09.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Revised: 09/17/2022] [Accepted: 09/19/2022] [Indexed: 11/04/2022]
Abstract
PURPOSE This meta-analysis was to critically evaluate the effects of Internet-based cognitive behavioral therapy (ICBT) on the symptoms of anxiety and depression in cancer patients. METHODS Eight Chinese and English databases (CNKI, Wanfang, VIP, CBM, Cochrane Library, PubMed, Embase, and PsycINFO) were systematically searched from the inception of databases to May 2022 for relevant randomized controlled trials (RCTs). According to the Cochrane Collaboration criteria, two reviewers independently assessed the risk of bias and extract data from included studies. All analyses were performed with Review Manager 5.4. RESULTS Thirteen qualified studies were included in the meta-analysis, twelve of which reported the effect of ICBT on anxiety in 2079 cancer patients; thirteen of the studies reported the effect of ICBT on depression in 2179 patients. The meta-analysis indicated that ICBT was effective in improving anxiety [SMD = -0.37, 95%CI (-0.62, -0.12), P < 0.01, I2 = 86%] and depression [SMD = -0.27, 95%CI (-0.44, -0.09), P < 0.01, I2 = 72%] symptoms in cancer patients, especially those undergoing anti-cancer treatment. Therapist-guided ICBT was more effective than self-directed ICBT. ICBT lasting for ≤12 weeks could relieve anxiety and depressive symptoms of cancer patients. ICBT with number of modules ≥5 had a small effect on anxiety and depression relief while ICBT with number of modules <5 was found to be ineffective. CONCLUSIONS ICBT lasting for ≤12 weeks, especially therapist-directed, helps relieve the anxiety and depressive symptoms of cancer patients. The ideal number of modules for ICBT and its long-term efficacy need to be validated by more studies of higher-quality.

Abstract
INTRODUCTION Many patients with cancer experience severe psychological distress, but as a result of various barriers, few of them receive psycho-oncological support. E-mental health interventions try to overcome some of these barriers and the limitation of healthcare offers, enabling patients with cancer to better cope with psychological distress. In the proposed trial, we aim to assess the efficacy and cost-effectiveness of the manualised e-mental health intervention Make It Training- Mindfulness-Based and Skills-Based Distress Reduction in Oncology. Make It Training is a self-guided and web-based psycho-oncological intervention, which includes elements of cognitive behavioural therapy, mindfulness-based stress reduction and acceptance and commitment therapy. The training supports the patients over a period of 4 months. We expect the Make It Training to be superior to treatment as usual optimised (TAU-O) in terms of reducing distress after completing the intervention (T1, primary endpoint). METHODS AND ANALYSIS The study comprises a multicentre, prospective, randomised controlled confirmatory interventional trial with two parallel arms. The proposed trial incorporates four distinct measurement time points: the baseline assessment before randomisation, a post-treatment assessment and 3 and 6 month follow-up assessments. We will include patients who have received a cancer diagnosis in the past 12 months, are in a curative treatment setting, are 18-65 years old, have given informed consent and experience high perceived psychological distress (Hospital Anxiety and Depression Scale ≥13) for at least 1 week. Patients will be randomised into two groups (Make It vs TAU-O). The aim is to allocate 600 patients with cancer and include 556 into the intention to treat analysis. The primary endpoint, distress, will be analysed using a baseline-adjusted ANCOVA for distress measurement once the intervention (T1) has been completed, with study arm as a binary factor, baseline as continuous measurement and study centre as an additional categorical covariate. ETHICS AND DISSEMINATION The Ethics Committee of the Medical Faculty Essen has approved the study (21-10076-BO). Results will be published in peer-reviewed journals, conference presentations, the project website, and among self-help organisations.

Abstract
BACKGROUND Over the past 15 years, there has been substantial growth in web-based psychological interventions. We summarize evidence regarding the efficacy of web-based self-directed psychological interventions on depressive, anxiety and distress symptoms in people living with a chronic health condition. METHOD We searched Medline, PsycINFO, CINAHL, EMBASE databases and Cochrane Database from 1990 to 1 May 2019. English language papers of randomized controlled trials (usual care or waitlist control) of web-based psychological interventions with a primary or secondary aim to reduce anxiety, depression or distress in adults with a chronic health condition were eligible. Results were assessed using narrative synthases and random-effects meta-analyses. RESULTS In total 70 eligible studies across 17 health conditions [most commonly: cancer (k = 20), chronic pain (k = 9), arthritis (k = 6) and multiple sclerosis (k = 5), diabetes (k = 4), fibromyalgia (k = 4)] were identified. Interventions were based on CBT principles in 46 (66%) studies and 42 (60%) included a facilitator. When combining all chronic health conditions, web-based interventions were more efficacious than control conditions in reducing symptoms of depression g = 0.30 (95% CI 0.22-0.39), anxiety g = 0.19 (95% CI 0.12-0.27), and distress g = 0.36 (95% CI 0.23-0.49). CONCLUSION Evidence regarding effectiveness for specific chronic health conditions was inconsistent. While self-guided online psychological interventions may help to reduce symptoms of anxiety, depression and distress in people with chronic health conditions in general, it is unclear if these interventions are effective for specific health conditions. More high-quality evidence is needed before definite conclusions can be made.

Abstract
INTRODUCTION Cancer-affected patients experience high distress due to various burdens. One way to expand psycho-oncological support is through digital interventions. This protocol describes the development and structure of a web-based psycho-oncological intervention, the Make It Training optimized. This intervention is currently evaluated in the Reduct trial, a multicenter randomized controlled trial. METHODS The Make It Training optimized was developed in six steps: A patient need and demand assessment, development and acceptability analysis of a prototype, the formation of a patient advisory council, the revision of the training, implementation into a web app, and the development of a motivation and evaluation plan. RESULTS Through a process of establishing cancer-affected patients' needs, prototype testing, and patient involvement, the Make It Training optimized was developed by a multidisciplinary team and implemented in a web app. It consists of 16 interactive self-guided modules which can be completed within 16 weeks. DISCUSSION Intervention protocols can increase transparency and increase the likelihood of developing effective web-based interventions. This protocol describes the process and results of developing a patient-oriented intervention. Future research should focus on the further personalization of web-based psycho-oncological interventions and the potential benefits of combining multiple psychotherapeutic approaches.

Abstract
INTRODUCTION Although a high percentage of patients with cancer experience severe psychological distress, few of them receive psycho-oncological care, largely due to barriers on the side of patients and healthcare providers that pose great challenges to delivering such care. In response, low-threshold, self-guided eHealth interventions can enable patients with cancer to deal independently and effectively with disease-related challenges and distress. Mindfulness and Skills-Based Distress Reduction in Oncology Training, nicknamed Make It Training, is one such innovative, self-guided eHealth intervention. In our study, we propose to assess different characteristics of such patients in order to define target populations for Make It Training, evaluate the intervention in terms of its usability, feasibility and sustainability and gather longitudinal data concerning the intervention's efficacy. METHODS AND ANALYSIS Self-guided and web-based Make It Training consists of eight 30 min modules involving the use of techniques of mindfulness therapy, cognitive-behavioural therapy and acceptance and commitment therapy to be completed in a 4-month period. In our observational study, adult patients with cancer who possess adequate German language skills and provide their informed consent will be recruited at Essen, Erlangen and Tübingen University Hospitals at outpatient oncological institutions and via online channels. Patients will undergo a baseline online assessment (T0), an assessment directly after completing the intervention (T1) and assessments 3 and 6 months later (T2 and T3, respectively). With the results of those assessments, we will perform descriptive analyses of their sociodemographic and medical data, compare means and conduct regression analyses. ETHICS AND DISSEMINATION The Ethics Committees of the University Hospitals Essen, Erlangen and Tübingen have approved the study (19-8643-BO, 27_19 B, 293/2018BO1). Results will be published in peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER DRKS00017119.
