# An Overview of Tools and Technologies for Anxiety and Depression Management Using AI
## 5 Evaluation of AI Tools--Case Studies  
### Quantitative Evaluation  
Multiple studies have been undertaken to determine the effectiveness of apps, virtual therapists, wearable devices, and virtual reality therapies in controlling and reducing symptoms of anxiety and depression. In relation to MoodKit, a 30-day trial including 226 individuals revealed a noteworthy decrease in depression, however, there was no significant impact on anxiety [106]. Separate research, with 159 participants from around 200 nations, discovered that MoodTools has the ability to overcome obstacles associated with conventional psychotherapy. Furthermore, the usage of the software did not result in any decline in their mental well-being [107]. It may be inferred that these applications have the potential to increase access to health and wellness services or activities, hence enhancing users' everyday life.

Figure 6: Trends in Research Focus Areas Over Time. The study conducted by [PERSON] et al. revealed that the Gear S3 Frontier smartwatch, a wearable device, was able to detect subjective data such as mood, physical activity, and sleep. These data were then used to classify individuals into different categories of depression. The study also found a strong correlation between the depression scores reported by the participants and the data collected by the smartwatch [108]. Conversely, 4-week observational research with 55 healthy people found that the BioBase program effectively decreased anxiety and improved their mental well-being. The participants said that they found the application to be user-friendly, with 70% indicating that they would suggest it to a friend. The results indicate that BioBase might be a successful intervention for managing stress and enhancing general well-being, especially for individuals with elevated stress levels. Simultaneously, two studies were performed to assess the efficacy of the \"Spire Health Tag\" in monitoring respiratory rate and its use in managing anxiety, stress, and other related psychological problems. The initial study showcased the efficacy of utilizing the method to monitor and regulate anxiety and stress levels in people suffering from persistent pain [6]. The second trial found that participants had a decrease in both stress and anxiety following the intervention [70]. Positive outcomes have been observed from research conducted on the \"Woebot\" chatbot. A total of 70 individuals who received assistance for symptoms of anxiety and depression took part in the initial survey. The study conducted by [PERSON] et al. found that participants had a noteworthy decrease in symptoms associated with sadness and anxiety [109]. A further study conducted by [PERSON] et al. revealed that Woebot effectively alleviated symptoms of sadness and anxiety among college students over a two-week period of sessions. Younger received a favorable rating from 4517 consumers, who utilized it for a duration of 4 weeks. The app led to a reduction in symptoms of anxiety and sadness within the initial 2 weeks of usage, and these improvements were sustained until the end of the trial. A recent study conducted by [PERSON] and [PERSON] has demonstrated that the chatbot \"Tess\" is highly helpful in reducing feelings of anxiety in subjects [110]. Finally, with relation to virtual mental health therapy, the study examined its efficacy in addressing stress and anxiety. The research had 61 individuals, who saw substantial decreases in anxiety (34%) and stress (32%). The results indicate that utilizing virtual treatment in the metaverse is both possible and secure, and it is linked to quantifiable enhancements in mental health results [80]. In general, the efficacy of online services for mental health treatment has been proven, and there is increasing evidence supporting the effectiveness of mental health treatment and support provided through mobile applications [111].
