The authors of (Madububambachu et al., 2024)
study carry out a systematic analysis of machine
learning techniques applied in the diagnosis of men-
tal health disorders, with an emphasis on univer-
sity students. The study includes 30 papers pub-
lished between 2011 and 2024 that explore Convo-
lutional Neural Networks, Support Vector Machine,
Random Forest and deep neural networks algorithms
for diagnosing conditions such as depression, anxiety,
PTSD, ADHD and schizophrenia. The study applies a
PRISMA methodology to collect and analyze relevant
articles. Inclusion criteria were based on keywords
such as ”deep learning” and ”predict mental health,”
searching for relevant papers in recognized databases,
including IEEE Xplore and ScienceDirect. The ana-
lyzed data comes from various sources, such as fMRI
images, EEG signals, text data from social media and
medical surveys.
The study stands out for obtaining satisfactory
performances. The CNN and Random Forest mod-
els performed highly, with up to 99% accuracy, in di-
agnosing depression and anxiety. Social media text
and EEG analysis have proven to be effective tools
for prediction. The application of CNN and RF algo-
rithms on GPS and EEG data achieved an accuracy of
80%-99%, depending on the specifics of the dataset,
and the SVM algorithm demonstrated high efficiency
in detecting brain structural changes through imaging
data, reaching AUC (Area under the ROC Curve) of
up to 0.93.
The authors conclude the paper (Madububam-
bachu et al., 2024) that although machine learning
models show promise for diagnosing mental disor-
ders, there are important limitations, such as lim-
ited access to large datasets and the interpretability of
complex models such as neural networks. The study
suggests that standardization and the use of more di-
verse and longitudinal data sets could improve the
accuracy of diagnoses and the ease of implementing
these models in clinical practice.
The article (Rahman and Kohli, 2024) explores
the mental health issues facing international students,
using machine learning techniques to analyze the de-
mographic, cultural and psychosocial factors that in-
fluence this category. The main aim was to create
a predictive model based on machine learning that
could identify the risk of depression among interna-
tional students in the UK. This approach is motivated
by increasing cases of depression and anxiety among
international students, often associated with academic
stress, financial difficulties, culture shock and other
adjustment problems.
The research was based on two unique data sets,
the first obtained through a survey applied to a group
of 87 international students between February and
March 2023 used for the training part of the model,
and the second used for testing contains data from
201 international students and was used to train and
test depression prediction models. The second set
is known as A Dataset of Students’ Mental Health
and Help-Seeking Behaviors in a Multicultural En-
vironment. In the study (Rahman and Kohli, 2024),
four machine learning algorithms were used: Logis-
tic Regression, Decision Tree, Random Forest and K-
Nearest Neighbors. The performance evaluation of
each model was done by accuracy, sensitivity, speci-
ficity, precision, and AU-ROC curve metrics.
The results obtained emphasize the importance
of specific demographic and psychosocial factors in
the prediction of depression. The main contribu-
tors to international students’ mental health problems
were found to include financial difficulties, academic
stress, homesickness, isolation, and culture shock.
Specifically, students in the 21-25 and 26-30 age cat-
egories, women and singles are more prone to depres-
sion and anxiety. The results also show that students
who have little social support or feel excluded from
the community have a higher risk of mental health
problems. In terms of algorithm efficiency, the Ran-
dom Forest model had the highest accuracy of 80%,
demonstrating a better ability to identify depressed
students. It had a high specificity in correctly iden-
tifying cases without depression, but a lower sensitiv-
ity in identifying positive cases, suggesting a stronger
performance in confirming mental well-being than in
detecting the risk of depression. Although the results
obtained in (Rahman and Kohli, 2024) are very good,
a major limitation of the study is the relatively small
size of the samples, both of the primary and secondary
sets.
A paper aiming to detect and predict mental health
disorders among students by applying various ma-
chine learning techniques is (Sahu and Debbarma,
2022). The authors tested the performance of the al-
gorithms: Logistic regression, decision trees, random
forest, closest neighbors k, and neural network to pre-
dict the risk of mental disorders among young peo-
ple. In the study a data set with 5,840 records was
used. To evaluate the models the authors used the
confusion matrix and calculated the accuracy, preci-
sion, sensitivity and AUC-ROC. The Neural Network
model demonstrated the highest accuracy of 99.03%,
being the best performer in predicting the risk of men-
tal disorders in students. The random forest and K-
nearest neighbor algorithms also scored highly, sug-
gesting their effectiveness in mental health assess-
