Easy access to mental health care is something most people in Pakistan are deprived of. With mental health care becoming increasingly expensive and there being only 1 mental health professional for approximately 500,000 people, the domain of mental health care needs a serious reevaluation [1,2]. The inherent elusive nature of diagnosing mental health disorders warrant the need for some kind of automated tool that aids users in their diagnostic journey. Mental health ailments are serious issues faced by people of all ages. These issues can result in varying outcomes. Some cases cause minor hindrances in someone’s day to day life whereas others can result in someone taking their own life. There is no certain explanation as to what someone ends up doing as a result of their deteriorating mental health [3]. This makes mental health disorders a serious issue that needs to be dealt with swiftly. Mental health refers to a state of well-being in which an individual realizes his or her own abilities to cope with the normal stresses of life, work productively and fruitfully, and is able to make useful contributions to his or her society and community [4,5]. This state can be considered as one of the most important factors towards leading a fulfilling life and having an overall positive impact on society in general. On the opposite end of this spectrum, mental health disorders are conditions that can affect your behavior, mood and thinking. They can hinder your ability to carry out mundane everyday tasks and they can be extremely overpowering and can leave the people going through them with feelings of angst, anger and even despair [6,7]. These disorders can have life long impacts on people diagnosed and even worse impacts on some of the people who are not diagnosed. Mental health disorders can manifest at any age which makes them some of the most elusive ailments to diagnose. Developing countries like Pakistan where the majority of the population lives below the poverty line face mental health problems on a scale that is difficult to comprehend. This makes mental health assistance something that is not easily accessible [8,9]. More importantly, the stigma surrounding mental health care in Pakistan makes its access burdensome. These reasons prove how important it is to further explore and analyze mental health issues and concerns in Pakistan. With approximately 918 million people facing mental health problems worldwide, the mental health dilemma has never been greater. Due to the widespread stigma surrounding mental health which leads to the societal rejection of mental health problems in Pakistan, this crucial issue has not been able to gain the traction it should have. This is one of the major reasons why mental health professionals are not available in all parts of Pakistan [10,11]. The implications of this can be estimated from the fact that according to the World Health Organization (WHO) there is one mental health professional for every 500,000 people in Pakistan [12,13]. This is a staggeringly low number since the mental health patients in Pakistan approximate out to be 4% of the entire populus. With such low numbers of mental health professionals, there is a dire need for mental health education among the masses and for there to be some platform people can visit to periodically check in on their mental health. Machine learning plays important role in automating diagnsotic processes of t types like cardiac issues [14] The differetn need for a platform that can accurately classify mental health diseases in people based on their responses to questions asked by mental health professionals cannot be overstated. Mental health disorders are complex and varied, with symptoms that can often overlap or mimic other conditions [15,16,17]. This makes accurate diagnosis and effective treatment a significant challenge for mental health professionals [18,19]. A platform that can systematically evaluate an individual’s responses to a standardized set of questions can help to streamline the diagnostic process and provide more accurate and timely diagnosis [1,20,21,22,23]. Additionally, such a platform can provide valuable insights into patterns and trends in mental health disorders, helping to inform public policy and allocate resources to where they are most needed. Overall, the development of a robust platform for mental health diagnosis has the potential to greatly improve outcomes for mental health patients, and is an important step towards improving mental healthcare globallyc [24,25,26]. However, the platform does not aim to replace the role of mental health professionals or provide medical advice [27,28,29]. It will solely serve as a tool to support mental health professionals and provide guidance and resources for users. Additionally, the platform and its results may be subject to the limitations and challenges, such as data quality, model interpretability, and user acceptance, which will be addressed through appropriate solutions and strategies.

The use of artificial intelligence in the field of mental health is supported by years of research done by the pioneers of this field. These researches focus on all aspects of mental health disease detection, classification and evaluation. The review of these papers shows the following three major categories that have been thoroughly worked on in this field. In their paper (Chung and Teo, 2022) [2] talk about the different mental health diseases they have studied and understood during their research. They discuss possible detection and classification techniques for schizophrenia, depression, bipolar disorder, and anxiety. They conclude that despite there not being any groundbreaking results in this domain, researchers are steadily able to come closer and closer to attaining a solution for mental health disease detection and classification by getting better results with every iteration. In their book (Artificial Intelligence in Behavioral and Mental Health Care, 2016) [3] the authors discuss all of the different ML/DL models and techniques that can be used for mental health disease detection. Going into detail about technologies like Machine Learning, Artificial Neural Networks, Machine perception and sensing, affective computing and many more, they conclude that machines and comprehensive algorithms are able to gain keen insights and generate better inference on patterns that are too complex for human beings to detect. This supports their finding that comprehensive artificial models and algorithms are better at finding disease markers in human beings because of their innate ability to understand the complex correlations in data. (Graham et al., 2019) [4] have reviewed 28 studies that use Electronic Health Records (EHRs) to classify mental health illnesses. They have concluded that using EHRs from mood rating scales, questionnaires on social media platforms and brain imaging data to classify mental health diseases like depression, schizophrenia or other psychiatric illnesses, and suicide ideation and attempts “revealed high accuracies and provided excellent examples of AI’s potential in mental healthcare”. It should be noted that in all of the 28 studies that were analyzed in this report, there were no clear performance metrics that were broadcasted which shows that the implementation of such artificially intelligent. In their research Luxton, D. D. (Luxton, 2013) [5]. Artificial Intelligence in Psychological Practice: Current and Future Applications and Implications the author discusses at length the emergence and prevalence of AI in every field of work today and its bright future with continued and ongoing investments. They consider this and conclude the undoubtable potential of AI in the field of mental health care. Leaning on the historic importance of the field of psychology and its influence on the development of AI itself from the theory of how neurons learn to the “cognitive revolution” in psychology in the 1960s all were critical concepts to the further realization of AI. This intermingling of fields the author describes as a strong reason for AI to become an equally substantial tool in the field of psychology where it may serve to benefit patients, health care providers, and society by enhancing care, increasing efficiency, and improving access to quality services. Ellen L Lee (Lee et al., 2021) [6] and others describe the current state of AI’s use in health care where it has become increasingly used in radiology and oncology yet remains unexceptionally used or researched for neurobiological health. The research is the product of a study to ascertain and provide an overview of the approaches Artificial Intelligence can take expanding its use into mental health by improving and aiding all areas of diagnosis, prognosis, treatment and clinical/technological challenges. Describing some of the areas where AI can outright bring improvement the research deliberates on the objectivity, an efficiency of identification, personalization and empowerment all advancements the use of AI can bring while also discussing the caution its usage should take considering its ethical implications. In this study by Young Tak Jo and others (Jo et al., 2020) [7], several machine learning models were built using global and nodal network properties to classify individuals as schizophrenia patients or healthy controls. The machine learning algorithms used included Support Vector Machine (SVM), multinomial Naïve Bayes (NB), Random Forest (RF), and gradient boosting. The models were assessed using cross-validation, and the accuracy and area under the curve (AUC) were calculated. The XGBoost model based on nodal degree showed the highest performance, with a 66.3% accuracy and an AUC of 0.656. The models based on global network properties generally outperformed those based on nodal properties. The importance of each region of interest (ROI) was also evaluated, revealing patterns of involved brain regions and a higher contribution from ROIs in the right hemisphere. These findings demonstrate the potential of network analysis and machine learning methods in diagnosing schizophrenia and provide insights into the underlying brain connectivity patterns associated with the disorder. In the study conducted by (Srinivasagopalan et al., 2019) [8], a deep learning approach was employed to diagnose schizophrenic patients using fMRI data. The researchers explored various machine learning and deep learning techniques to achieve accurate classification. Logistic regression, support vector machines (SVM), and random forest models were implemented, with logistic regression achieving an accuracy of 0.8277, SVM achieving 0.7988, and random forest achieving 0.8333. However, the most promising results were obtained using a deep learning architecture consisting of three hidden layers and a dropout rate of 50This model achieved an impressive accuracy of 0.9444, highlighting the potential of deep learning for schizophrenia diagnosis. The study provides valuable insights into the effectiveness of different techniques in the context of mental health diagnosis, laying the foundation for future research and advancements in this field. In a study by Pläschke RN (Plaschke et al., 2017) [9], researchers aimed to address the limitations of previous whole-brain functional connectivity studies which achieved successful classifications of patients and healthy controls but provided limited specificity regarding the affected brain systems. To conduct the analysis, separate support vector machine classifications were performed on functional connectivity data obtained from patients suffering from schizophrenia, PD and older adults and young, healthy controls. The researchers utilized 12 task-based, meta-analytically defined networks and employed a nested 10-fold cross-validation scheme with 25 replications. The findings of this study indicate that the pattern-classification approach employed captured associations between clinical and developmental conditions and functional network integrity with a higher level of specificity compared to previous whole-brain analyses. The results for all the networks for Schizophrenia with control range from about 0.61 to 0.79 AUC. SCZ patients could be distinguished above chance from matched HCs based on RSFC in the Rew network with an accuracy of 68%. In a study by Anamika Ahmed and others (Ahmed et al., 2019) [10], researchers focused on the detection of depression, major depressive disorder and anxiety. It has been reported that over 50% of the total population in middle and high-income countries experience at least one of the aforementioned mental illnesses in their lifetime. Researchers proposed a model combining a standard psychological assessment with ML algorithms to diagnose the severity levels of the disorders. The model employed five different types of algorithms, Convolutional Neural Network, Support Vector Machine, Linear Discriminant Analysis, K Nearest Neighbour Classifier and Linear Regression. The algorithms were applied to two different datasets, one for anxiety and one for depression. The study aimed to compare the performance of the five algorithms against the respective datasets using various measurement metrics as evaluation criteria. The results demonstrated that in the proposed model, it was CNN algorithm that yielded the highest accuracy of 96% for anxiety and 96.8% for depression. In the study by Daniel Leightley and others (Leightley et al., 2018) [11], researchers focused on the mental health of soldiers and its impact on their operational effectiveness, health and overall well-being. With the prevalence of traumatic events experienced during military service, the development of PTSD is not uncommon. Although many studies have utilized probabilistic and regression modeling to estimate its likelihood, the increasing complexity and large quantities of data collected call for more sophisticated modeling methods. Therefore, the researchers for this study turned to ML classifiers as a means to generate advanced statistical models that can uncover patterns and behaviors within complex datasets. It has to be noted that the application of ML in PTSD detection has been limited thus far. The single study had utilized supervised ML for prediction, demonstrating the model’s capability to accurately detect probable PTSD in a Danish military cohort, but the study only used one ML technique and a small number of data points. To address the limitations, the dataset for this study consisted for 13,690 subjects and over 22 variables were used for testing. The classifiers used for this study include Support Vector Machines, Random Forests, Artificial Neural Networks and Bagging. The accuracies achieved for all the classifiers were 0.91, 0.97, 0.89 and 0.95 respectively. In another study done by Wanqing Xie and other researchers (Xie et al., 2022) [12], the prevalence of depression and anxiety has been highlighted. The current methods of using Self-Reported Anxiety Scale and Self-Reported Depression Scales are said to have limitations as they provide limited information and may not align with clinical diagnosis. To address this, a new approach is proposed by the researchers to extract features from facial expressions and movements captured in videos recorded while individuals complete the scales. The findings are combined with multimodal data with scale information, and a framework is developed to enhance the accuracy and reliability of the diagnostic process. A model with two branches is constructed, one for each scale. The branches utilize a Convolutional Neural Network to extract the features and a Long Short-Term Memory network is employed to further embed the expressions and capture connections between subsequent frames. The scale scores are transformed into one-hot format and fed into their respective branches, further enhancing the extraction of multimodal data information. The embeddings from both the branches are fused at the end to generate inference results for depression. Three different classification methods were used in this research to generate a classification model, SVM, Naive Bayes and AdaBoost. While SAS and SDS have the accuracy of 83.78% on their own, the model the researchers tested with reached the accuracy of 94.67%. The study done by Jina Kim and others (Kim et al., 2020) [13] presents a novel approach to identify mental illness through analyzing user-generated content on social media platforms. The authors recognized the potential of social media as a valuable source of information for mental health assessment and developed a deep learning model to automatically detect signs of mental illness. By leveraging a large dataset of user posts and associated mental health labels, the researchers trained their deep learning model using recurrent neural networks (RNNs) and attention mechanisms to capture the sequential and contextual information in the text. The findings showcased promising results, demonstrating the model’s ability to accurately detect mental illness with an impressive accuracy of 82of mental health assessment, highlighting the potential of utilizing social media data and deep learning techniques for early detection and intervention of mental health conditions in a scalable and non-intrusive manner. In this paper by Góngora Alonso S and others (Góngora et al., 2022) [14] the researchers aimed to assess the effectiveness of various machine learning algorithms in predicting hospitalization among patients with schizophrenia. They collected a comprehensive dataset comprising demographic information, clinical assessments, and historical records of hospitalized patients. The researchers implemented and compared different algorithms, including logistic regression, decision trees, random forests, support vector machines, and gradient boosting machines. The results of their study indicated that random forest and gradient boosting machines exhibited superior predictive performance, achieving an accuracy of 85% and 83% respectively, in identifying patients at risk of hospitalization. This research provides valuable insights into the potential of machine learning algorithms to aid in the early identification and intervention for individuals with schizophrenia, thereby facilitating more targeted and timely treatment strategies to reduce hospitalization rates.

After training the models, we obtained the following accuracy results: 74% for Random Forest, 76% for SVM, and approximately 76% for our deep neural network (prone to overfitting). These accuracy scores represent the models’ performance on the given dataset, indicating the percentage of correctly predicted outcomes. The SVM model achieved the highest accuracy at 76%, followed closely by deep neural networks with an accuracy score of 76%. However, the Random Forest Algorithm exhibited a slightly lower accuracy of around 74%.

This implemented deep learning models in this work are: LSTM, RNN and CNN. And there are four activation functions used on each model to test its output. And the LSTM out performs rest of the models and gave 100% accuracy with all the activation functions. And the second best accuracy is of CNN with 98.8%. Whereas the epochs are 10, batch size is 32 for all the models and activation functions. And mostly the dropout is 0% in all models with all activation functions tested. Accuracy plots are shown in the Figure 10

This reseach aimed at accurately diagnose mental health disorders based on the responses a user provides. The research’s main objective is to streamline the diagnostic process for mental health professionals and users and improve the accuracy and timeliness of diagnoses. The proposed solution addresses the problem statement by providing a platform that enables both mental health professionals and users to diagnose mental health illnesses more efficiently and accurately. The platform is user-friendly and can be accessed by both doctors and patients, making it accessible to a wide range of users. The AI model in the backend underwent comprehensive evaluation for accuracy score, F1 score, specificity, and sensitivity, revealing consistent performance across all metrics with a score of 73predictions on unseen data. While this score may be considered relatively modest, it serves as a solid foundation for future improvements. The evaluation results provide valuable insights into the model’s strengths and areas that require enhancement. By analyzing the factors contributing to the current performance and addressing them, the model can be iteratively refined and optimized to achieve higher accuracy and better overall predictions in the future In conclusion, It provides a solution that addresses the problem of the diagnostic process in mental health. The platform has been tested and proven to be effective, accurate, and user-friendly. With the Mental Health Classification, mental health professionals can now diagnose patients more efficiently and accurately, leading to improved mental health outcomes for patients.

The field of AI-based applications and solutions has a promising future, with recent examples demonstrating the real-world impact of AI. This potential is particularly evident in the diagnosis of mental health diseases, as discussed earlier in this paper. However, there are several steps that must be taken to further develop and improve the project. The first of these steps involves beta testing the web application at the local mental hospital Mental Health Institute, where real-world patients will participate and compare the AI’s predictions to their actual diagnosis. Additionally, testing with mental health professionals will be crucial to assess the effectiveness of the platform as an aiding tool and ensure that it accurately predicts mental health disorders while remaining consistent with their own conclusions about their patients. These two tests are a primary concern to assess the viability and effectiveness of the project. Another essential aspect of this project is enabling the application to take in negative feedback and improve its training and accuracy. This feedback loop will be vital to improving the overall performance of the platform and ensuring its reliability. Lastly, to improve the accuracy, scope, and depth of our model’s predictions, we must continue to expand and refine the dataset produced by this research. By doing so, we can further unlock the potential of this project and showcase its true capabilities. In conclusion, the current stage of this project, including its dataset, AI, and showcasing application, represents only the beginning of its potential. Through ongoing development and refinement, this project has the potential to make a significant impact on the diagnosis and treatment of mental health diseases.
