Background: Internet-based cognitive behavioral therapy (iCBT) is a necessary step toward increasing the accessibility of mental health services. Yet, few iCBT programs have been evaluated for their fidelity to the therapeutic principles of cognitive behavioral therapy (CBT) or usability standards. In addition, many existing iCBT programs do not include treatments targeting both anxiety and depression, which are commonly co-occurring conditions.
Objective: This study aims to evaluate the usability of Tranquility-a novel iCBT program for anxiety-and its fidelity to CBT principles. This study also aims to engage in a co-design process to adapt Tranquility to include treatment elements for depression.
Methods: CBT experts (n=6) and mental health-informed peers (n=6) reviewed the iCBT program Tranquility. CBT experts assessed Tranquility's fidelity to CBT principles and were asked to identify necessary interventions for depression by using 2 simulated client case examples. Mental health-informed peers engaged in 2 co-design focus groups to discuss adaptations to the existing anxiety program and the integration of interventions for depression. Both groups completed web-based surveys assessing the usability of Tranquility and the likelihood that they would recommend the program.
Results: The CBT experts' mean rating of Tranquility's fidelity to CBT principles was 91%, indicating a high fidelity to CBT. Further, 5 out of 6 CBT experts and all mental health-informed peers (all participants: 11/12, 88%) rated Tranquility as satisfactory, indicating that they may recommend Tranquility to others, and they rated its usability highly (mean 76.56, SD 14.07). Mental health-informed peers provided suggestions on how to leverage engagement with Tranquility (eg, adding incentives and notification control).
Conclusions: This preliminary study demonstrated the strong fidelity of Tranquility to CBT and usability standards. The results highlight the importance of involving stakeholders in the co-design process and future opportunities to increase engagement.

Article Synopsis
- The study emphasizes the importance of measuring therapist fidelity in cognitive behavioral therapy for insomnia (CBT-I), focusing on both adherence to treatment and the competence of delivery.
- Researchers developed reliable measures of therapist fidelity specifically for brief CBT-I and conducted a pilot study with veterans to evaluate their impact.
- Results indicated that higher therapist adherence was significantly linked to reduced depression, highlighting the influence of fidelity on treatment outcomes.

Objectives: Although several brief cognitive behavior therapy (CBT)-based treatments for dental fear have proven efficacious, these interventions remain largely unavailable outside of the specialty clinics in which they were developed. Leveraging technology, we sought to increase access to treatment for individuals with dental fear through the development of a mobile application (Dental FearLess).
Materials And Methods: To assess the resonance of our app as an avenue for dental fear treatment, we conducted a study assessing the usability, feasibility, and acceptability of the beta app.

Unlabelled: The rate of exposure to traumatic events is high globally, and post-traumatic stress disorder (PTSD) is one of the most serious consequences. It was reported that approximately 14 million people were affected by earthquakes in Turkey in February 2023. Cognitive Behavioral Therapy (CBT) is a therapeutic approach to treating PTSD and has a proven efficacy.

Decades of research have demonstrated the efficacy of cognitive behavioral therapies (CBTs) for a wide variety of psychiatric diagnoses, resulting in the inclusion of CBT as a first-line evidence-based practice (EBP) in treatment guidelines for mood and anxiety disorders. However, some research suggests that many providers do not implement EBPs as intended. Ongoing quality monitoring is needed to support EBP implementation and sustainability, but "gold standard" fidelity monitoring (e.

Studies have shown a high prevalence of trauma and PTSD among patients with severe mental illness, but relatively few studies have examined the outcomes of PTSD treatment for this patient group. The aim of this case-series was to assess the feasibility of a Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) intervention for PTSD in people with psychosis. The study examined the possibilities and obstacles when treating this population within clinical settings.
