Abstract

:
This study focuses on the development and evaluation of an AI-based digital therapeutic prototype for adolescent mental health management and disaster response. The system integrates real-time monitoring, AI-driven conversation analysis, personalized psychological treatment programs, and multimodal data analysis. An algorithm was developed to detect gaslighting and verbal abuse using a BERT-based classification model, achieving 85% accuracy in gaslighting detection and 87% accuracy in verbal abuse detection. Additionally, a psychological disaster-recovery support module was included, which demonstrated a 30% improvement in users’ stress reduction rates during simulated disaster scenarios. This study demonstrates that digital therapeutic approaches can significantly contribute to early intervention in adolescent mental health issues. Additionally, these approaches provide effective support during disasters. The developed prototype demonstrates the potential of AI and digital technology to innovate mental health management and disaster response strategies.

1. Introduction

With the advancement of digital technology and the widespread use of smartphones, adolescents’ online activities have increased, leading to the emergence of psychological violence in digital environments, particularly gaslighting and verbal abuse, as new social issues [1]. Gaslighting refers to the psychological manipulation of subtly altering another’s perception of reality to justify one’s wrongful behavior or confuse the victim [2]. It often involves denying or distorting facts, minimizing feelings, and shifting blame. For adolescents, gaslighting can lead to self-doubt, anxiety, depression, and difficulty trusting their own judgment. A study found that 73% of adolescents who experienced gaslighting reported lower self-esteem, and 68% had trouble forming healthy relationships [3].
Meanwhile, supporting the psychological recovery of adolescents in recent natural disasters and social crisis situations has emerged as an important challenge. According to the 2022 Disaster Yearbook, Gyeongsangbuk-do recorded the highest damage from natural disasters among 17 cities and provinces in Korea, with approximately 206.7 billion won [4]. These disaster situations can cause serious psychological trauma to adolescents. Without proper support, such trauma may lead to long-term mental health problems [5]. A longitudinal study of adolescents exposed to natural disasters found that 28% still experienced symptoms of post-traumatic stress disorder (PTSD) 2 years after the event. Additionally, 15% developed new-onset depression within 3 years of the disaster [6]. These findings highlight the need for long-term mental health support for disaster-affected adolescents.
The main objective of this study is to develop a digital therapeutic prototype that can manage adolescents’ psychological health and respond to disaster situations using AI technology. To achieve this, the study aims to design and integrate a real-time psychological-state-monitoring system focusing on gaslighting and verbal abuse detection, a system for providing personalized mental health advice through AI-based conversation analysis, and a disaster response module to support psychological recovery before and after crisis situations, thereby constructing a comprehensive digital therapeutic solution. Furthermore, by evaluating the effectiveness of the developed prototype through pilot service implementation, the study seeks to demonstrate the potential of AI technology to provide timely and effective support in adolescents’ daily psychological challenges and specific disaster situations.
This study aims to explore the possibility of integration with wellness solutions through the design, implementation, and evaluation of an AI-based digital therapeutic prototype. The research begins with a systematic literature review on digital therapeutics, wellness solutions, and AI applications in the field of mental health. It also includes system design and architecture development for an AI-based mental health management and disaster response prototype.
The process of implementing and optimizing core algorithms for real-time monitoring, gaslighting detection, and stress analysis is carried out. Data collection is conducted by deploying pilot services to selected groups of adolescent users, and multifaceted performance evaluation is performed based on technical indicators, clinical outcomes, and user experience. An in-depth analysis of the possibility of integration with existing wellness solutions is also conducted.
This study aims to evaluate the potential of effective support that AI technology can provide in adolescents’ daily psychological challenges and disaster situations. Through a critical analysis of the research results and limitations, along with suggestions for future research directions, the feasibility of realizing a comprehensive digital therapeutic solution is explored. This is expected to provide valuable insights into the effectiveness and applicability of AI-based digital therapeutics in the field of adolescent mental health management and disaster response.

2. Theoretical Background

2.1. Definition and Current Status of Digital Therapeutics

Digital therapeutics (DTx) are innovative medical devices that provide evidence-based therapeutic interventions through high-quality software programs aimed at preventing, managing, or treating medical disorders or diseases. They are distinct from general wellness apps or health management tools, requiring rigorous evidence of clinical efficacy and often subject to regulatory oversight [7]. The digital therapeutics market has been experiencing rapid growth, particularly in the fields of mental health management and chronic disease management. According to a report by Grand View Research, the global digital therapeutics market size was valued at $3.4 billion in 2021 and is projected to grow at a compound annual growth rate (CAGR) of 26.1% from 2022 to 2030 [8].
Key characteristics of digital therapeutics include evidence-based interventions, patient-facing software, the ability to collect and analyze patient data, potential for integration with other treatments or interventions, and, in many cases, the requirement for regulatory approval. In the field of mental health, recent developments include AI-based chatbots for depression management, virtual reality exposure therapy for anxiety disorders, and cognitive behavioral therapy (CBT) apps, demonstrating innovative advancements in this area [9].

2.2. Definition and Market Trends in Wellness Solutions

Wellness solutions encompass a wide range of products and services aimed at promoting health and preventing disease, with a focus on personalized healthcare. Unlike digital therapeutics, these are generally not regulated as medical devices and focus on maintaining and improving overall well-being rather than treating specific medical conditions [10]. The global wellness market has shown significant growth due to increased health awareness and the adoption of preventive healthcare approaches. According to a report by the Global Wellness Institute, the market is projected to grow from $4.9 trillion in 2019 to $7.0 trillion by 2025 [11].
Key trends in the wellness solutions market include personalized nutrition and fitness plans, mental health apps and mindfulness programs, sleep optimization technologies, wearable devices for health tracking, and corporate wellness programs. The COVID-19 pandemic particularly accelerated the adoption of digital wellness solutions by dramatically increasing demand for remote health monitoring and mental health support [12]. These trends indicate that wellness solutions play a crucial role in meeting the health management needs of modern society.

2.3. Classification and Comparison of Digital Therapeutics and Wellness Solutions

While digital therapeutics and wellness solutions share the common goal of improving health outcomes, they differ significantly in their approaches and characteristics. Digital therapeutics are designed for the prevention, management, and treatment of specific medical conditions, requiring rigorous regulatory approval processes and clinical trials to demonstrate efficacy [13,14]. In contrast, wellness solutions focus on general health improvement and disease prevention, typically not requiring regulatory approval and relying on more general health benefits [15].
Furthermore, there are differences between the two solutions in terms of data processing and integration with medical systems. Digital therapeutics often include more stringent data security and privacy measures, considering the sensitivity of medical information, and are more likely to be integrated into formal medical service provision and may be prescribed by medical professionals [16,17]. These differences significantly influence the development, application, and evaluation processes of each solution, and understanding them is essential for designing effective digital health management systems (Table 1).
Understanding these distinctions is crucial for developing systems that can effectively bridge the gap between digital therapeutics and wellness solutions, providing a more comprehensive approach to youth mental health management and disaster response.

3. Design of the AI-Based Adolescent Mental Health Management and Disaster Response System

3.1. Overall System Architecture

The proposed AI-based adolescent mental health management and disaster response system integrates several core components to provide a comprehensive solution. The architecture of this system is designed to ensure real-time monitoring, accurate analysis, and timely intervention. The system includes a data collection module that gathers various types of data from users’ smartphones and wearable devices, as well as an AI analysis engine that utilizes advanced machine-learning algorithms to process the collected data and detect patterns and potential risk factors.
A key component of the AI analysis engine is the BERT-based context encoder. This encoder leverages the power of Bidirectional Encoder Representations from Transformers (BERT) to capture deep contextual information from user-generated text data. By processing text bidirectionally, the BERT model can understand the nuances and context of language use, which is crucial for accurately detecting issues like gaslighting or verbal abuse.
Furthermore, the system incorporates Google’s multilingual BERT model to ensure effective language processing across diverse linguistic backgrounds. This integration allows the system to provide support for adolescents from various cultural and linguistic contexts, enhancing its global applicability and inclusivity.
Additionally, a real-time monitoring dashboard provides a visual representation of the user’s current psychological state and overall well-being, while an intervention module generates personalized recommendations and interventions based on AI analysis results. In crisis situations, a disaster response unit is activated to provide specialized support and guidance, and a secure data repository ensures the privacy and security of sensitive user data. An intuitive and engaging user interface that allows users to interact with the system and access resources is also a crucial component of this system.
This system operates as a continuous feedback loop, constantly updating analyses and recommendations based on new data inputs and user interactions. This enables effective management of adolescents’ psychological well-being and allows for rapid and appropriate responses in disaster situations. This integrated and innovative approach well demonstrates how AI technology can revolutionize mental health management and disaster response strategies.
The algorithm presented outlines a comprehensive AI-based system for managing adolescent mental health and responding to disasters (Algorithm 1). This innovative approach integrates multiple data sources and advanced AI techniques to provide personalized mental health support and timely disaster response.

3.2. Real-Time Psychological State Monitoring and Gaslighting Detection Algorithm

The real-time psychological state monitoring and gaslighting detection algorithm developed in this study is a core component of the AI-based adolescent mental health management system. This algorithm utilizes natural language processing (NLP) technologies and machine-learning models to analyze users’ digital communications and identify potential signs of psychological distress or manipulation. In particular, it uses a fine-tuned BERT (Bidirectional Encoder Representations from Transformers) model to classify text and determine the presence of gaslighting or verbal abuse.
The algorithm’s process consists of data collection, preprocessing, feature extraction, BERT-based classification, sentiment analysis, risk assessment, and alert generation. Through this process, the system can monitor the user’s psychological state in real-time and generate alerts for immediate intervention when necessary. Performance evaluation of the gaslighting detection algorithm resulted in 85% accuracy, 82% precision, 87% recall, and an F1 score of 0.84. This suggests that the algorithm demonstrates high performance in identifying potential gaslighting cases and maintains a good balance between precision and recall (Table 2).
These results demonstrate that the algorithm performs well in identifying potential gaslighting cases and maintains a balanced trade-off between precision and recall.

3.3. AI Algorithms and Data Analysis Techniques

The system employs a variety of AI algorithms and data analysis techniques to provide accurate and timely mental health support. The key components of this AI-driven approach are detailed below:

3.3.1. Natural Language Processing (NLP) for Text Analysis

In this study, advanced natural language processing (NLP) techniques are employed to analyze users’ textual data. The NLP pipeline consists of stages including text preprocessing, feature extraction, sentiment analysis, and topic modeling. The text preprocessing stage involves tokenization using the NLTK library, lowercasing and special character removal, and stopword removal and lemmatization. In the feature extraction stage, TF–IDF vectorization and word embedding using a pre-trained GloVe model are performed. For sentiment analysis, a fine-tuned BERT model is used to classify sentiments and output positive, negative, or neutral sentiments along with confidence scores. Lastly, in the topic-modeling stage, Latent Dirichlet Allocation (LDA) is employed to identify prevalent topics in user communications and track changes in interests or concerns over time. This comprehensive NLP approach contributes to a more accurate analysis and understanding of users’ psychological states.
For data fusion, this study adopted a late fusion approach using a random forest classifier. In this method, each modality is processed individually and then combined at the decision level, applying a weighted voting mechanism based on the reliability of each modality. Additionally, to personalize the system, transfer learning techniques were introduced to adapt the global model to individual users, and a continuous learning approach was implemented to update the model based on user feedback and new data. Table 3 shows, these multi-modal fusion and personalization techniques enable a more accurate and contextualized understanding of the user’s mental state.

3.3.2. Time Series Analysis for Trend Detection

In this study, time series analysis techniques were applied to identify long-term trends and patterns in users’ mental health. The following methodologies were adopted:
  • Data Preprocessing:
    -
    Resampling techniques were applied to convert irregularly spaced data into uniform time series.
    -
    Multiple imputation methods were used to handle missing values.
  • Trend Analysis:
    -
    Moving average smoothing techniques were applied to reduce noise in the data.
    -
    Exponential smoothing was used for short-term predictions.
    -
    An ARIMA (AutoRegressive Integrated Moving Average) model was implemented for complex time series data analysis.
  • Change Point Detection:
    -
    The PELT (Pruned Exact Linear Time) algorithm was applied to identify significant changes in users’ mental health trajectories.
  • Periodicity Anaysis:
    -
    Fourier analysis was performed to detect periodic patterns in mood and behavior.
    -
    This provided useful information for identifying potential triggers or rhythms in mental health fluctuations.

3.3.3. Reinforcement Learning for Adaptive Interventions

In this study, a system was developed that utilizes reinforcement learning to optimize intervention strategies over time. This system was implemented through a problem formulation that defines the user’s current mental health state, recent activities, and time of day as the state, various intervention types (e.g., CBT exercises, mindfulness activities, social support suggestions) as actions, and mood score improvements and app engagement as rewards. For the algorithm, a Deep Q-Network (DQN) was adopted to effectively handle large state–action spaces, along with experience replay for improved sample efficiency and a decreasing ε-greedy exploration strategy.
The model architecture consisted of an input layer with 64 units, two fully connected hidden layers (128 and 64 units) using ReLU activation functions, and an output layer producing Q-values for each possible action. In the training process, initial training was conducted on simulation data based on clinical guidelines, followed by continuous updates to the model based on actual user interactions and outcomes. To ensure safety, the action space was restricted to clinically approved interventions, and a human-in-the-loop system was implemented to monitor and override AI decisions when necessary. This approach enables safe and effective AI-driven interventions in adolescent mental health management.

3.3.4. Personalized Profile Module

To enhance the system’s ability to provide tailored support, a personalized profile module was implemented. This module utilizes machine-learning techniques to create and continuously update individual user profiles based on their interactions, preferences, and behavioral patterns. Key features include collaborative filtering to identify similar users and recommend interventions that have been effective for peers, dynamic preference learning to adapt to changes in user interests and needs over time, and contextual bandits for personalized content recommendation, balancing exploration of new interventions with exploitation of known effective strategies. This comprehensive approach ensures that the system can provide highly personalized and adaptive support to each user, continuously improving its recommendations based on individual and collective user data.
To capture a more comprehensive understanding of users’ emotional states, two additional modules were integrated into the system. The first is a voice emotion recognition module, which enhances the system’s ability to analyze emotional cues in speech. This module extracts acoustic features such as pitch, energy, and spectral characteristics from the user’s voice. It then utilizes a deep neural network, trained on labeled emotional speech datasets, to classify emotions into categories including happiness, sadness, anger, fear, and neutral. The module provides real-time emotion probability scores during voice interactions, offering a dynamic assessment of the user’s emotional state through their speech patterns. The second module is a facial expression analysis module, which complements the voice analysis by examining visual cues. This module employs advanced computer vision techniques for face detection and landmark localization. It uses a convolutional neural network to extract facial features and classify facial expressions into basic emotion categories. The facial expression analysis is integrated with the voice emotion recognition module, enabling multimodal emotion analysis. This combined approach allows for a more nuanced and accurate assessment of the user’s emotional state by considering both auditory and visual emotional cues simultaneously.
By integrating these advanced AI algorithms and data analysis techniques, our system can provide highly personalized, adaptive, and effective mental health support to adolescents. The combination of NLP, multi-modal analysis, time series prediction, and reinforcement learning enables a comprehensive understanding of the user’s mental state and the ability to provide timely and appropriate interventions. The system’s effectiveness was evident in several key areas. The NLP module exhibited high accuracy in sentiment analysis, while the time series analysis successfully identified long-term trends in users’ mental health. The reinforcement-learning component showed promising results in optimizing intervention strategies, and the personalized profile module significantly improved user engagement. Additionally, the non-verbal signal analysis modules enhanced the system’s ability to detect subtle emotional cues, contributing to a more holistic assessment of users’ mental states.

3.4. Disaster Response Module and Stress Management Solution

The disaster response module is designed to provide users with appropriate support and guidance in crisis situations. This module automatically detects whether users are in disaster-affected areas by utilizing user location data and external APIs, and integrates with the system’s core functions to provide specialized interventions tailored to disaster scenarios.
To enhance the accuracy and reliability of risk assessment, a multi-layered model has been implemented, incorporating various data sources and analytical techniques. This comprehensive approach includes geospatial analysis utilizing real-time location data and disaster information APIs, behavioral analysis examining changes in user patterns, sentiment analysis of user communications and self-reported data, and historical data analysis considering past responses to similar situations. By integrating these diverse analytical methods, the model provides a more nuanced and comprehensive understanding of the user’s risk level, allowing for more targeted and effective interventions. This multi-faceted approach enables a holistic assessment of immediate physical risks, stress indicators, emotional states, coping capacities, and potential outcomes, ultimately leading to more precise risk evaluation and tailored support strategies.
To ensure the highest level of care and accuracy, especially in high-risk situations, an expert oversight system has been implemented. This system incorporates real-time monitoring using AI algorithms to continuously analyze user data and flag potentially critical situations. Flagged cases are immediately added to a priority queue for human expert review. For high-risk cases, any AI-suggested interventions must be approved by a qualified mental health professional before being sent to the user. In cases of imminent danger, the system can immediately alert local emergency services while simultaneously notifying on-call mental health professionals. This human-in-the-loop approach combines the scalability and speed of AI with the nuanced judgment of human experts, ensuring that users receive appropriate and timely care, especially in critical situations.
To enable users to easily find necessary resources in disaster situations, the module includes features for locating nearby shelters, medical facilities, and other essential resources. Additionally, it supports communication in emergency situations, allowing users to easily contact emergency contacts and provide updates on their safety status. These features help users reduce psychological burden and cope safely in crisis situations through immediate and practical support.
The stress management solution in this module includes continuous monitoring that tracks stress indicators through physiological data and self-reported measurements. Using machine learning models to predict stress levels and identify potential stressors, it provides effective support for each user through adaptive interventions that offer personalized stress-reduction techniques. Furthermore, it provides progress-tracking functionality that allows users to monitor their stress levels over time and observe the impact of various interventions. The effectiveness of this system was demonstrated in a simulation study with a group of adolescent participants, where users of the module showed a 30% improvement in stress reduction compared to the control group.
The integration of our digital therapeutic device and wellness solution enables a data-driven approach that utilizes multi-modal analysis for more accurate and comprehensive health assessments. This integrated solution employs multi-modal data collection to gather data from various sources, including psychological assessments, wellness app usage patterns, wearable device sensors, and user-reported information. It then applies advanced analytics using sophisticated AI algorithms to process and analyze multi-modal data, identifying correlations and patterns that may not be apparent from a single data source. Based on this, it performs holistic health profiling to generate a comprehensive health profile that considers mental, physical, and social well-being factors. Through personalized intervention design, it develops tailored intervention strategies that address both mental health issues and general wellness goals. Additionally, it employs continuous optimization using machine-learning techniques to continuously improve and optimize the effectiveness of interventions based on user responses and outcomes (Table 4).
