Objectives

Narrative objectives1

The final objective of this research is to create an application that enables daily visualization of mental health and provides tailored interventions, both digital content and medical care, based on the individual's condition. As a preparatory step, we will identify practical and sustainable indicators for monitoring mental health and develop severity prediction algorithms using these indicators.

Basic objectives2

Others

Basic objectives -Others

Mental health problems in the workplace, from mild to severe, negatively affect individuals and society. Yet, tools that allow daily monitoring, early detection, and timely intervention remain insufficient. Because the invisible state of mental health lacks clear criteria for visualization, there is a pressing need to establish practical and sustainable indicators and to develop severity prediction algorithms that make use of them.

Assessment

Primary outcomes

Mental health problems in the workplace, from mild to severe, negatively affect individuals and society. Yet, tools that allow daily monitoring, early detection, and timely intervention remain insufficient. Because the invisible state of mental health lacks clear criteria for visualization, there is a pressing need to establish practical and sustainable indicators and to develop severity prediction algorithms that make use of them.

Key secondary outcomes

We will examine whether the severity of mental health states, classified as mild, moderate, or severe based on psychological measures related to current and future sleep, anxiety, and depression, can be predicted using machine learning algorithms applied to other simple indicators.
We will evaluate implementation and adherence rates of each application and questionnaire to identify tools that are feasible for daily use.
We will also assess which background factors strongly influence the primary algorithmic outcomes, thereby evaluating which approaches are most effective.
Furthermore, we will investigate whether there are correlations between daily questionnaires, heart rate variability, voice measurements, and weekly follow-up results, as well as their temporal fluctuations.
In addition, we will explore whether combining other indicators can predict both the "current state" and "subsequent changes" in mental health.
