Sensors, Vol. 19, Pages 3693: Predicting Depression, Anxiety, and Stress Levels from Videos Using the Facial Action Coding System

We present the first study in the literature that has aimed to determine Depression Anxiety Stress Scale (DASS) levels by analyzing facial expressions using Facial Action Coding System (FACS) by means of a unique noninvasive architecture on three layers designed to offer high accuracy and fast convergence: in the first layer, Active Appearance Models (AAM) and a set of multiclass Support Vector Machines (SVM) are used for Action Unit (AU) classification; in the second layer, a matrix is built containing the AUs’ intensity levels; and in the third layer, an optimal feedforward neural network (FFNN) analyzes the matrix from the second layer in a pattern recognition task, predicting the DASS levels. We obtained 87.2% accuracy for depression, 77.9% for anxiety, and 90.2% for stress. The average prediction time was 64 s, and the architecture could be used in real time, allowing health practitioners to evaluate the evolution of DASS levels over time. The architecture could discriminate with 93% accuracy between healthy subjects and those affected by Major Depressive Disorder (MDD) or Post-traumatic Stress Disorder (PTSD), and 85% for Generalized Anxiety Disorder (GAD). For the first time in the literature, we determined a set of correlations between DASS, induced emotions, and FACS, which led to an increase in accuracy of 5%. When tested on AVEC 2014 and ANUStressDB, the method offered 5% higher accuracy, sensitivity, and specificity compared to other state-of-the-art met...

Conclusion: Our study suggests there are high prevalence rates for mental health and addiction conditions in patients attending the out-of-hours clinic 18 months after the wildfires, with significant associations between multiple variables and likely PTSD, MDD, and GAD. Further studies are needed to explore the impact of population-based mental health interventions on the long-term mental health effects of the wildfires.

Conclusions: Anxious/preoccupied attachment is associated with an increased risk of multiple anxiety comorbidities in MDD patients. A longitudinal study with a larger sample size is needed to identify the causal relationship of anxious/preoccupied attachment and anxiety comorbidities during the course of MDD.

BACKGROUND: The Contrast Avoidance Model postulates that individuals with generalized anxiety disorder (GAD) fear a sharp spike in negative emotion, and thus, prefer to worry to maintain their negative affect rather than being in a more euthymic state, suc...

Abstract Research suggests that low-income adults accessing employment services have experienced high levels of trauma exposure and associated consequences. Moreover, the health-related effects of trauma undermine employment and employability. A trauma-informed protocol-trauma screening, brief intervention, and referral to treatment or T-SBIRT-was therefore implemented within employment service programs serving low-income urban residents. To assess the feasibility of integrating T-SBIRT within employment services, five domains were explored as follows: suitability, acceptability, client adherence, provider adheren...

This study examined the association between generalized anxiety disorder (GAD), posttraumatic stress disorder (PTSD), SUD, depression, and HIV diagnosis among adults aged 50 and older, and the disparities by age, sex, and race/ethnicity. Data were obtained from Cerner Corporation's Health Facts® database. Multivariable logistic regression models were used to determine the associations between GAD, PTSD, SUD, and depression, and HIV diagnosis. Results were also stratified by age group, sex, and race/ethnicity. Overall, there were positive associations between SUD, depression, GAD, PTSD and HIV; and differences by age, s...

AbstractThe American College of Rheumatology (ACR) 2016 criteria for fibromyalgia (FM) is recommended for use in primary and referral setting. However, neither the ACR 2016 nor its predecessor ACR 2010 criteria have been validated in a referral setting. We hypothesized that the presence of higher comorbidities in the referral care setting may affect the performance of the ACR 2016. All patients referred to a tertiary care hospital with widespread pain for more than 3  months were screened using (1) the ACR 2016 criteria and (2) by a blinded expert physician (using ACR 1990 criteria). Using the ACR 1990 as reference st...

CONCLUSIONS: The prevalence of PTSD in the current study population is relatively high and the fact that a significant number of adolescents were afraid to stay inside a building following the earthquake calls for further investigation and treatments.
