Handheld or head-mounted? An experimental comparison of the potential of augmented reality for animal phobia treatment using smartphone and HoloLens 2

Exposure therapy is an effective treatment for specific phobia that could be further enhanced through Augmented Reality, a novel technology that can facilitate implementation of gradual exposure and promote treatment acceptability. Effective exposure interventions require stimuli evoking high levels of anxiety. Therefore, it is important to ascertain whether animals can induce anxiety in distinct Augmented Reality modalities, such as Head-Mounted Displays and smartphones, which can differ in user experience and technological embodiment. This study compared the anxiety inducing potential and experienced realism of a spider within the HoloLens 2 Augmented Reality headset and an Augmented Reality smartphone application. Sixty-five participants were exposed to a virtual spider in a 5-step Behavioral Approach Task through both the HoloLens 2 head-mounted display and the PHOBOS Augmented Reality smartphone application. Participants reported Subjective Units of Distress at each step and physiological arousal was measured using heart rate and Skin Conductance. Results show that both technological modalities induced self-reported anxiety for spiders in a Behavioral Approach Task task in a non-clinical sample. The Hololens 2 modality was also related to an skin conductance (SC) increase. Perceived realism did not differ between modalities but was associated with increased anxiety in the HoloLens 2 modality. Findings demonstrate that both implemented modalities have potential for enabling Augmented Reality Exposure Therapy, although the role of experienced realism merits additional investigation. Future research should assess the effectiveness of Augmented Reality Exposure Therapy in clinical samples and assess whether new extended reality modalities, such as passthrough virtual reality, could accommodate observed limitations and improve Augmented Reality Exposure Therapy experiences and outcomes

Usage of unguided, guided, and blended care for depression offered in routine clinical care: Lessons learned

Introduction: Internet-delivered psychotherapy is often considered to be a promising way to extend mental healthcare services around the world. Research findings that have emerged over the past two decades have strengthened this claim. However, very little is known about the usage of internet-delivered psychotherapy in real-life circumstances. Methods: The current study explored the real-life usage of depressiehulp.be, a publicly available online platform for depression that offers pure self-help, online guided self-help, and blended treatment for depression in Flanders, Belgium, using data collected from 2656 participants between May 2018 and May 2022. Results: Both duration of engagement with the online platform and number of exercises completed increased with increasing levels of therapist guidance. Findings also showed a particular pattern of engagement for each of the online treatments. Overall, participants completed most exercises during the first days of treatment. However, participants using pure online self-help showed the fastest decrease of engagement over time, with most dropping out after completing a few exercises, and more than half of all participants who enrolled in the self-help programme did not even begin the programme. In both guided and blended treatment, participants tended to show higher levels of engagement with the online platform. In each treatment modality, a relatively small but notable group of participants showed high levels of engagement. There was no relationship between severity of depression and duration of engagement. Conclusions: The current study demonstrates the importance of therapist support in online interventions and offers additional insights into how, and to what extent, online platforms are used. Future research should explore clinical impact and policy implications
